    GTX 980m iMac support

    I recently got a 2010 27" iMac for free! Some further research concluded that the MXM slot in the iMac has been proven to work with a GTX 880m, including Mac OS! I used to play with a 7970 ghz edition, but ended up selling it for some more projects. I've been lagging along on a 5870 2gb and thought that with my switch to the free iMac, I might as well update my gpu. Heres the problem I was faced with: the 880m is a little underpowered on stock clocks. So, after even more research I discovered that the 980m was around the same as a 7970 performance wise. I ended up grabbing a deal on an 880m for only 160$, but I did want to share my findings with you guys. *WARNING* ONLY 2009, 2010, AND 2011 IMACS HAVE THE MXM SLOT!!!! IF YOU ARE USING A 2012+ YOU CANNOT UPGRADE YOUR GPU So the 980m used to work all the way up to mac os sierra. It's now high sierra, but the fix is still pretty simple. What you will need: -thermal pads -copper ram heatsinks/ one of the specialized backplates that cools MXM memory modules. -Your graphics card -YOU NEED an imac 2011 gpu heatsink -GOOD thermal paste (Preferably liquid metal if youre comfortable with that) -IMAC 2010 power supply *As far as i know the power supply's between these 3 imac's are interchangeable, but the largest one is the 2010 variant, at the 310 watts, and the others are much lower. *Just from tdp we know that the 980m is 115w and the cpu's on these guys are most commonly 95w, thats allready 200 with out hdd, all the other components etc. -nvidia web drivers READ THE FOLLOWING DIRECTIONS CAREFULLY Step 1: You must have all your mac os/ windows partitions set up with bootcamp, and MAKE SURE it boots into Mac OS and wont boot into anything else when you start it up AFTER the upgrade. *Remember nvidia web drivers must be installed before you upgrae Step 2: dremel/ cnc/ remove a couple parts of the VRM section of the imac 2011 heatsink, (You want your card IN HAND so you are able to make sure it fits correctly. step 3: Assemble the gpu assembly step 4: Re assemble the imac, with the new gpu. *This is where is gets slightly harder* step 5: You want to reset your iMac's System Management Controller, otherwise known as SMC. *DO NOT FLASH NVRAM OR PRAM, or you will have to redo the whole process, after you put your old gpu in to fix all the bootcamp problems and such *You can do this by plugging the power cord into your imac, waiting 30 seconds and NOT turning it on, unplug your power cord, wait 30 seconds, then plug it back in. Wait another 30 seconds, then turn it on. (But not before reading the following to be prepared:) step 6: You need to force Mac OS to work with an unsupported card. this is a pretty simple process if you are comfortable with terminal. * I couldn't have found this without this page: https://www.ifixit.com/Story/18646/Successful_iMac_Upgrade_to_GTX_880M " To make a non-apple provided Nvidia graphics card work in macOS Sierra you need to do the following… Start the computer in safe mode by holding shift. Get your BoardID by running this command in terminal echo "<result>$(ioreg -rd1 -c IOPlatformExpertDevice | awk -F'["|"]' '/board-id/{print $4}')</result>" Open the AppleGraphicsControl Kext using this command sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist Use the arrow keys to go down until you see <key>ConfigMap</key> followed by a bunch of keys and strings. LOOK FOR YOUR BOARD ID… IF IT IS LISTED: Change the string to <string>none</string> IF IT IS NOT LISTED: Add it in the same format as the ones listed. Save the file by pressing Ctrl+O, then enter. Exit by pressing Ctrl+X Rebuild the kernel cache using the following two commands: sudo kextcache -system-prelinked-kernel AND sudo kextcache -system-caches Have Fun! Theoretically this should work, and I would love for somebody to try as I got an 880m instead. Just keep in mind this is all from research and has not been proven to work. Be sure to research this subject before you try it.
  2. I decided to buy a 980M for my R2. I have gone down the rabbit hole in these forums (Here and notebook review) but most of it appears to be from 2012-2016. I am not planning on overclocking, and for now am replacing the 2x 675m sli (Alienware Tech support fried one of my 675M's with a thermal pad on the GPU, yes a thermal pad instead of paste, see photo.) with a single 980M solution. I have finally managed to get this site to send a confirmation email, then turns out I wait a week download the unlocked A11 BIOS. Do I even still need it? I will pay if I need it for sure to get it faster. What I'm getting at, is this still a thing? I have read that Nvidia added support for the R2 in their driver, so no modded driver is needed. Did alienware add support for maxwell with the A12 BIOS? I can't find a difinitive answer. Sorry, I have read so much about this the past week, but haven't come up with a cut and dry yes or no.
  3. I've read a lot of conflicting posts about thermal pads for the CPU and GPU on the Alienware m15x. There are a lot of pictures out there detailing all of the different sized thermal pads that you need. In my experience, 1.5mm pads are perfect for everything on the Dell 980m and the 920xm. I was using 0.5mm pads at the time that I replaced both, so having the exact sizes was important. I think that I might have actually fried my 5850m in part due to not having thick enough thermal pads. I discovered that they had had not been making contact with the heatsink at all. I tried following the guide on techinferno and noticed that my gpu was actually bending (a lot) and certain areas weren't even making contact at all. I tried different layering of thermal pads through trial and error, looking for imprints of vrms and such. 1.5mm on everything worked the best. Some people are putting thermal pads on things that the manufacturers don't even put them on. I can't say what thicknesses are needed for these, but it will be more than 1.5mm. Anyway, I hope that this helps someone. I was using Arctic brand 0.5 thermal pads and stacking them in my testing. I have 1.5mm pads on the way now.

    m15x 980m Upgrade

    Hey all, decided to get a cheap m15x and managed to get an msi gtx 980m along with it. I've ordered two fans I'm planning on trying to mod in, one being a 13 cfm dell m6700 fan and the other a 11cfm m4700 fan to try and help with the heat. I currently have a 210 or 240 watt? power adapter and a 920xm installed so I'm planning on undervolting the gpu. Is it best to do this inside afterburner or is better to do try and mod the vbios? Also will I have to flash the dell vbios onto my card to get it working with my system or will I just have to modify the .INF file?
  5. I have installed my 980M on myR2, Got the 8 Beeps, I thought with the A12 BIOS and Windows 10 it should have worked. Oh well, going to tear it back down and put the 675M's back in. Ijust got promoted and am downloading the A11 unlocked BIOS . So, Next teardown I am going to be completely ready. I just want to get this in and see if I can get it working before my return window passes. I have posted a few places here, and on Notebook Review on several threads about this stuff, and have received one response. Is this site still active? Do I need a modified driver still, all that stuff looks really old, 2013-2016 type stuff. I need to know about 2018. I have read that Nvidia added support for the maxwell in m18x r2. Am I wrong? Can someone offer advice? I have read that this thing should have been plug and play with windows 10 on Eurocom, Do I just need their driver? PLEASE HELP!!! Thank You!!!
  6. Hey all, just got my m17xr4 and put my 980m from my m15x (old) in it. I was able to score much higher graphics score in firestrike even though it is a much older machine. I made a custom vbios for the m15x to get rid of any throttling, and am in the process of making on for the m17xr4 but I'm wondering if there is anything else I have missed to deal with the throttling. any help would be appreciated
  7. Good time, everyone. Got an AW M18x R1 with 580M SLI, 330W PSU, 100W heatsink and A05 svl7 unlocked BIOS. Is it possible to upgrade the GPUs to a single 980M with Optimus? Got a very good deal on 980M, don't know if it will work. P.S. Searched lots of sites including this, but didn't find the exact answer. Would appreciate any help, thanks in advance.
  8. Hi I'm new in this forum, but I'm reading and learning a lot from your experiences. (thank you) I bought a used asus ROG G750JY, which had problems with its nvidia (error 43), freeze, and blank screen. I tried changing the system (win10 --> win8 --> win8.1 --> win10), the drivers, and finally the vbios. I do not know what kind of action the previous owner did on notebook, but at the moment it seems that the video card has 4 gigs and not 8. I tried to update with many versions of nvflash, both from windows and dos, but without success. Then I saved the current bios and changed the values through maxwell bios tweaker. I do not know if the default values were correct for the card, so I ran a cpu and ram downclock. flashing the bios in this way, the board is recognized and started without any problems. Now, how can I proceed to solve the problem entirely? I tried to flash 8 gig BIOS ASUS but I get "gpu mismatch" errors. Thank you very much
  9. Hello, Recently, my Radeon R9 M290X stopped working (everything indicates it's broken). So, I was thinking about buying a Geforce 980m but everything I read about installing a 980m in an Alienware (GPU upgrade) mentioned about having to install modified drivers and turning off the driver signature enforcement. My question is: why do we have to install modified drivers? Is there a way to install drivers directly from the official nVidia website? Modifying the BIOS and inserting UEFI drivers, or modifying the vBIOS? in order to use the official drivers? Thanks in advance, I await a response.
  10. Hello, dudes! I've successfully upgrade my laptop to 980M and install the newest driver. But when I played games like PUBG or Watchdog2, the GPU core clock is not stable at 1000+Mhz due to PerfCap Reason: Pwr. It makes my game experience very badAnyone could help me, thank you all!

    Alienware M17X R3 UEFI

    Hi guys. As with the title, is there any way to get a m17x r3 to use UEFI or is this just a pipe dream? I read over the internet that this requires Dell company itself to refactor the BIOS and release it to the public. Well if that's the case many believe it would be easier to land a man on Mars then to get Dell's help on this issue. Does the hardware itself plays a roll in updating to UEFI ? Well if the motherboard itself doesn't support UEFI and its more of a hardware limitation rather than a software, please let me know and I'll let this dream go, once and for all. Well if not, does anyone else knows of any other way to get a m17x r3 to UEFI-capable ? Imagine fast-booting into win10 and more importantly, a chance to get a 980M working in a m17x r3. (from my understanding 880M is as far as the m17x r3 can go as the 980M requires UEFI-capabilities) I know my laptop is approaching 7 years old and by now most m17xr3 are phrased out but i still believe there are some owners out there still kicking about with their madly modded-out r3s (like me). Thanks for the read
  12. Hi there. I've been noticing performance drops on some games associated with low GPU usage. The games run fine at 60 fps + for the most part and the gpu usage is above 80%. But in some areas the fps drops dramatically to mid 30fps and the gpu usage drops to 30-40% too. Even on Borderlands Pre-sequel, where the game usually runs at 120-90 fps, sometimes drops to 40-35 fps (with physx on low setting wich i think is the same as OFF). My CPU usage never hit 99% or near that on that sections so i hope it isn't the CPU bootlecking. And it isn't Temperature Throttle, because the temps are about 70º on those moments (my gpu only gets really hot when its usage get's above de 90%). Other thing i noticed was that with the latest nvidia drivers that i got to work (376.33), when i turned physx to higger settings, the performance got a drop but it didn't show any physx effects anywhere on the game. Another thing that doesn't work is the Nvidia Gamestream because it always gives error trying to connect from another device. Performance wise, it looks like i'm getting the same performance as my girfriends clevo P651SE that has an 970m, and on that laptop, i can connect to nvidia gamestream using the same method that fails on my laptop. Could the reason be the new drivers? It is getting more dificult to install new drivers on this model and i can see that some functionalities are starting to fail. By the way, i don't overclock any of my components. My System Specs are : - Clevo P150EM with PremaBios V2 and PremaVbios V2 Flashed - nvidia 980M - I7-3820QM - 16gb of RAM - Windows 7 64Bits - 180W powersupply with 1 year of use ( I bought a new one from a CLEVO P651SE because it was smaller than my stock one, and my original was starting to fail, just outputting 130W from the 180W, making my internal display dimm the Light when i pushed my 980m just a little bit more) Thanks in advance

    Clevo P150SM Upgrade. What to do!?

    Hi, I have a Clevo P150SM (Not SM-A, just SM) with a GTX 770m, bought over 2 years ago. I wanted to upgrade to a GTX 9xxm series, a GTX 970m or even a 980m to max it out. However I have 2 issues. I don't know if I have to do something on the BIOS for the 9xxm series card to work, I hear a lot that I have to modify the BIOS but it's not clear so I would really appreciate if someone knowledgeable adresses this for me. The 2nd issue, is more to do about the 980m only. My Clevo P150SM has a 180W power brick, I don't intend to overclock anything, be it CPU or GPU and I'll play at 1600x900 with mostly high/some ultra settings(no AA or MSAA) with V-Sync ON. I'm sure a 180W brick can handle a 970m + a 47W processor (i7-4910mq) but I'm no so sure about the 980m, which is the one I have my sights on, so is a 180W brick safe or is it recomended to get a 200W+ power brick? And if so, where can I get one that's capable of connecting to the P150SM(with the Barrel Round Plug Tip).
  14. Hi everyone! I have aw17 (4900mq, 330W psu) upgraded to 980m 4G (1617 dev. id, g-sync). Gpu-z sensors monitoring informs about downclock to 937MHz under full gpu Driver ver. 372.70 (self modded inf). Stock bios. WIn10. Any way to fix this?
  15. Hi guys, I was trying to install GTX 980M from MSI laptop in my Alienware, but i still can't install driver for this GPU. Can you help me ? Please look at the Hardware ID and give me a tip what should i do to install it. Thanks Hardware ID of GTX980M is PCI\VEN_10DE&DEV_1617&SUBSYS_05AA1028 ( This is in device manager ). What should i do to make it working, or how should i edit nvdmi.inf to make it working ???
  16. Dear Respected Members, I want your advice please: Upgrading my Clevo P570WM from GTX 880m SLI to GTX 980m SLI (=$2000) or the new GTX 1070/1080 if applicable? I need to verify if it will support one or 2 of them in SLI?? or Get a new Clevo P870 or Eurocom Sky 9XE Unlocked with the 980m's SLI (=$3500)? and then I have to sell my old Beast and if your advice is to go for the new system, what is the best choice?: 1- GTX 980m SLI 2- GTX 980 Desktop 3- Just wait for the GTX 980 Desktop SLI? 4- GTX 1070/1080 if applicable 5- Something else Best Regards.
  17. It seems NVIDIA is getting to ready to release two new mobile Maxwell GPUs in Q2 2016, the GTX 970MX and GTX 980MX. With the company already dominating the high end notebook market and 14nm/16nm next generation GPUs on their way like Polaris, the timing of this release seems a little odd. Both GPUs will be positioned as slightly more powerful than their existing GTX 970M and GTX 980M counterparts with increased CUDA cores, texture units, and clock speed while retaining the same TDP. In addition to the aforementioned, the 970MX has 56 ROPs vs 48 in the 970M while the 980M and 980MX have the same 64 ROPs. WCCFTech created a table which shows the differences between the new GPUs and existing ones: Model GeForce GTX 980 Laptop Version GeForce GTX 980MX GeForce GTX 980M GeForce GTX 970MX GeForce GTX 970M GeForce GTX 965M GeForce GTX 960M Architecture Maxwell Maxwell Maxwell Maxwell Maxwell Maxwell Maxwell GPU GM204 GM204 GM204 GM204 GM204 GM204 GM107 CUDA cores 2048 1664 1536 1408 1280 1024 640 Texture Units 128 104 96 88 80 64 40 Raster Devices 64 64 64 56 48 32 16 Clock Speed 1218 MHz 1048 MHz 1038 MHz 941 MHz 924 MHz 950 MHz 1097 MHz Memory Bus 256-bit 256-bit 256-bit 192-bit 192-bit 128-bit 128-bit Amount of memory 8 GB GDDR5 8/4 GB GDDR5 8/4 GB GDDR5 3/6 GB GDDR5 3/6 GB GDDR5 4 GB GDDR5 4 GB GDDR5 Memory Frequency 7008 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz Memory Bandwidth 224 GB/s 160 GB / s 160 GB / s 120 GB / s 120 GB / s 80 GB/s 80 GB/s TDP ~150W 125W 125W 100W 100W 90W 75W Table Source: WCCFTech There's no word on what the price will be for these new cards or what notebooks will feature them but if I had to guess, I'd say the usual suspects like Alienware, Clevo, MSI and Asus will be among the first to have these ready.

  19. Not sure where to post this so I just added it to general. I just upgraded my M17X R4 120Hz from 675m to a 980m and I'm having a problem I hope someone here can help me with. To start: It was installed correctly and successfully on Windows 10 (I wanted to start somewhere more certain). Everything worked fine and everything read fine (as far as the graphics card goes). After I was sure everything was working properly, I reverted to Windows 7. As I read, with the current unlocked BIOS A11 (posted on this site) it's capable of running 9xxM series in windows 7. When I installed 7 on this laptop soon after buying it (reformatted old HDD, moved to bay 1, inserted 500GB SSD in bay 0 and installed 7 OS on it) I installed selecting the UEFI option and the drive is in GPT. As mentioned, I have Unlocked A11 BIOS (thank you to the maker on this site!). Anyway, once I reverted to 7 it started to boot up and said it needed to run startup repair. I allowed it and it froze once the bar filled at the bottom. Upon restarting I tried once more.. same thing. I tried to "start normally" and it starts boot looping. I then changed "Load Legacy Option Rom" from disable to enable. This causes the 8 beep post issue immediately upon power on. This problem doesn't exist when this option is disabled. I then utilized the HDMI trick (I made a separate post for this the other day. Connect HDMI out to any screen and it will cause post on the laptop screen [but not on the external device]. Can then immediately disconnect once post has occured and works fine with no error or beeps). This let it boot up and I'm able to get to the desktop and everything works fine. Can even run screen at 120Hz. I ran diagnostics on the card, checked drivers.. everything is reading correctly. This is workable, but far from an ideal solution as I need to have a cable and some kind of HDMI screen available just to boot up every time. I have two option here and I'm hoping someone can provide a little guidance one way or the other. I can either fix the boot looping issue on "Legacy Rom - disabled" (it hangs on classpnp.sys when I try safe mode if that information helps at all). OR, I need to find a way for it to post when "Legacy Rom - enable" without connecting to an HDMI device (just plugging in the cable doesn't work. It has to be connected to something on the other end). For the first, I have tried start up repair and tried repairing using my WIN 7 disc but it doesn't actually pull up the menu. It just shows the windows loading screen and then freezes after a while. For the second I have tried changing different video options in hopes it will post on boot without connecting to an external or tried to find a way to keep the HDMI port active without something being in it. I can make no progress with either of these as I'm unaware exactly what exaclty the selections change. I currently have it set to PEG. Also, I have tried bios reset through removing all power sources and the 2032 CMOS and holding power button 30 seconds. Didn't help. Any help or guidance would be greatly appreciated. Feel free to ask any questions you have that could assist in ascertaining the source of the problem in either instance. As a last resort, I could go back to 10, but I would really rather not. The R4 (in Dell's words) isn't being tested for compatibility. Many features don't seem to work, and overall I just much prefer 7.
  20. Hey guys, I know I've seen many forums covering this topic (including this one) but I just recently installed the 980m in my M17x R4 with the 120Hz screen. I found an interesting trick that helped tremendously. Just wanted to share in case it may benefit someone else. I won't include all of the steps to the process as those are thoroughly covered elsewhere. Okay, so you have the card (980m) installed but it doesn't recognize it yet (no drivers / need to change bios settings etc.) meaning that you immediately get the 8 beep error on startup. A lot of forums say you need to reinsert your old graphics card to access menus, then switch it back to 980m. I've found that through using the HDMI out and connecting to another screen, it will actually stop the 8 beeps and you regain post. It will post only on your laptop, not the screen connected through HDMI. I believe this is due to the 120Hz not being supported when connected to an external screen, it makes it function as a 60Hz and seems to resolve the 8 beep posting issue making it possible to change your settings and even install the (modified) drivers on the desktop. I hope this helps to ease someone else's process in the future.
  21. Specs: 4900MQ, 16Gb, 980m SLI. I recently upgraded my GPU from 780m SLI to 980m SLI. I am facing performance issues. I had very low passmark 43xx, I mainly play dota 2 and with my 780m sli, i used to get around 120FPS on medium settings. With the new 980m sli i am getting anywhere from 80fps to 30fps on highest settings. And FPS is not stable at all. If i even drop the settings to medium or low I still get the same fps. I got the latest drivers for everything and made sure that SLI is turned on. I am missing anything? Any help would be appreciated.
  22. So I didn't like that the memory on my 980m only clocked to 6.4 GHz after raising the voltage to 1.48V from 1.35V, and wanted my memory to run even faster. I knew someone with a spare 970, so we made a deal where I buy the card, and if it still worked after I switched all the memory chips, he'd buy it back (for reduced amount if it could no longer do 7GHz, but at least 6GHz). Long story short, he bought the card back and I got faster memory. MSI 970 4GB Lightning original memory: Samsung K4G41325FC-HC28 (7GHz rating, 8GHz max overclock) MSI 980m 4GB original memory: Hynix H5GQ4H24MFR-T2C (6 GHz rating, 6.4GHz max overclock) Both cards are GM204 chips. The 980m has one less CUDA core block enabled than the 970, but it has the full 256-bit memory interface and L2 cache with no 3.5GB issues, while the 970 is 224-bit with 1/8th of the L2 cache disabled. Both cards are 4GB with 8 memory chips. I highly suspected this memory swap would work because video cards read literally nothing from a memory chip. There is no asking for what the chip is or even the capacity. They write data to it and hope they can read it back. Memory manufacturer information read by programs like GPU-z isn't even read from the memory. It's set by an on-board resistor. I also had changed multiple memory chips in the past, so was fairly confident I could physically do the job. I started with just one chip switched from both cards. This meant both cards were running a mix of memory from different manufacturers and of different speed ratings, but same internal DRAM array configuration. Both cards worked. Here is a picture of the 980m with one chip switched over: Now how did the cards react? The 980m behaved no differently. No change in max overclock. The 970 though... I expected it to be slower... but... 970 with 1 Hynix chip, 7 Samsung (originally 8 Samsung) 7GHz = Artifacts like a crashed NES even at desktop 6GHz = Artifacts like a crashed NES even at desktop 5GHz = Artifacts like a crashed NES even at desktop 2GHz = Fully Stable, 2d and 3d I didn't try 3GHz or 4GHz, but yeah, HUGE clock decrease. I shrugged though and kept switching all the memory figuring that as long as it worked at any speed, I could figure out the issue later. With switching more chips through 7/8 switched there was no change in max memory clocks. What was really fun was when I had 7/8 chips done. My GDDR5 stencil got stuck and ripped 3 pads off the final Samsung chip. Needless to say there was a very long swearing spree. Looking up the datasheet I found that 2 pads were GND, and a 3rd was some active low reset. Hoping that the reset was unused, I checked the 970's side of the pad and found it was hardwired to GND. This meant the signal was unused. I also got a solder ball on a sliver of one of the GND pads that was left, so I was effectively only missing a single GND connection. I put the mangled 8th chip in the 980m and it worked. Net gain after all of this... 25 MHz max overclock. Something was obviously missing. I figured I would switch the memory manufacturer resistor, hoping that would do something. I saw that Clyde found this resistor on a k5000m, and switching it to the Hynix value from Samsung had no effect for him. He found that for Hynix on the k5000m the value was 35k Ohms, and for Samsung 45k Ohms. I searched the ENTIRE card and never found a single 35k Ohm resistor. Meanwhile the 970 also worked with all 8 chips swapped, at a paltry 2.1 GHz. Then I got lucky. Someone with a Clevo 980m killed his card when trying to change resistor values to raise his memory voltage. His card had Samsung memory. He sent his card to me to fix, and after doing so I spent hours comparing every single resistor on our boards looking for a variation. Outside of VRM resistors there was just a single difference: On his card (his is shown here) the boxed resistor was 20k Ohms. On mine it was 15k Ohms. I scraped my resistor with a straight edge razor (I could not find a single unused 20k resistor on any of my dead boards) raising it to 19.2k, hoping it was close enough. And it was! Prior to this I also raised the memory voltage a little more from 1.48V to 1.53V. My max stable clocks prior to the ID resistor change were 6552 MHz. They are now 6930 MHz. 378 Mhz improvement. Here's a 3dm11 run at 7.5 GHz (not stable, but still ran) http://www.3dmark.com/3dm11/10673982 Now what about the poor 2GHz 970? I found its memory ID resistor too: Memory improved from 2.1 GHz to 6.264 GHz. Surprisingly the memory was slower than it was on the 980m. I expected the 970's vBIOS to have looser timings built in to run the memory faster. As for why the memory was over 100MHz slower than the 980m, 980m actually has better memory cooling than the 970. With the core at 61C I read the 970's backside memory at 86C with an IR thermometer. The Meanwhile the 980m has active cooling on all memory chips, so they will be cooler than the core. In addition, the 980m's memory traces are slightly shorter, which may also help. The 980m at 6.93 GHz is still slower than the 8 GHz that the 970 was capable of with the same memory. I'm not sure why this is. Maybe memory timings are still an issue. Maybe since MSI never released a Hynix version of the 970 meant leftover timings for an older card like a 680 were run, instead of looser timings that should have been used (I know in system BIOS tons of old, unused code get pushed on generation after generation). I don't know, just guessing. Talking to someone who knows how this stuff works would be great. I still want 8 GHz. Some more pics. Here's one with the 970 about to get its 3rd and 4th Hynix chips: Here's my 980m with all memory switched to Samsung. Sorry for the blurriness: So in summary: 1. It is possible to mix Samsung and Hynix memory, or switch entirely from one manufacturer to another, with some limitations. 2. There is a resistor on the pcb that is responsible for telling the GPU what memory manufacturer is connected to it. This affects memory timings, and maybe termination. It has a large impact on memory speed, especially for Hynix memory. This resistor value can be changed to another manufacturer. It is not guaranteed that the vBIOS will contain the other manufacturer's timings. If it does they may not be 100% correct for your replacement memory. 3. If you take a card meant for Hynix memory, you can mix Samsung memory of the same size if it is a faster memory. If the memory is the same speed, the penalty for running Samsung with Hynix timings may hurt memory clocks. 4. If you take a card meant for Samsung memory, you cannot mix any Hynix memory without MAJOR clock speed reductions without also changing the memory manufacturer resistor. It is not guaranteed that the vBIOS will contain the other manufacturer's timings, or if it does 100% proper timings for your specific memory. 5. For Kepler cards the Samsung resistor value is 45k, and for Hynix 35k. For Maxwell cards the Samsung resistor value is 20k, and Hynix 15k. Next up is changing the hardware ID to be a 980 notebook. Clyde also found HWID to have an impact on the number of CUDA core blocks enabled. In about a month I can get a hold of a 970m that someone is willing to let me measure the resistor values on. It has the same pcb as the 980m. Does Nvidia still laser cut the GPU core package? We will find out.

  23. Can the new Alienware 13" be fitted with a GTX 980M and 4980HQ?
  24. Hi all, I had pretty good success with my GPU upgrade a few months back, although at the same time I realised my battery was on it's last legs. I bought a replacement that I had to send back as it was faulty, but now I have got a working one and it's running very close to the edge in terms of power draw. If I run any heavy GPU benchmarks, or even max out the CPU for any length of time on battery it will just power off in an instant. It's doing this both on Windows and Linux (the latter with the nvidia card completely disabled). I'm running Prema's Mods for both Bios and vBios. Is this something that other people have experienced? Shouldn't the power consumption be scaled back when running on battery just for this reason? Perhaps this is something the prema BIOS turns on/off, but I can't seem to find any other references to this. Any ideas how to manage this? Thanks in advance, Pete
  25. Hi all I just bought two clevo mxm GTX980M for my alienware 18 r3, after install on my laptop and install driver, I found that there is no sli option in driver setting. After I review these two gpus in gpu-z, I found one 980M pci id is 1617, the other one is 13D7. I think this may be the reason that sli cannot be enabled. Anyone knows what should I do to make the sli option work? the 1617 one is from P770 ZM-G with g-sync build in.
