  1. Hi everyone. I have had a bit of search around but I have not found anything yet pertaining to my issue. I have an Alienware 17 R1 (Late 2013 model). It originally came with an i7 4900, a GTX780m, 120hz 3D panel with intel graphics disabled. I have just got a Dell GTX980m 8GB (BIOS 84.04.2F.00.79 - Device ID 10DE 13D7-1028 05AE) and put it in and it works fine getting into windows and running 2D. However, when I run any decent 3D the graphics constantly hits power limiter and downclocks to around 800mhz. This is confirmed to be power limit in gpuz perfcap reason and this happens regardless of temperature. Running a Unigine benchmark has actually showed the card's performance to be just lower than the 780m I replaced. Using HWiNFO64 I have found that the GPU is being limited to 80 watts. It briefly goes up to over 100 watts but drops to 80. Power Supply is 240 watt This laptop always runs off mains power and the battery only lasts a few seconds regardless of apparent charge. I should also mention that I have tried, Setting nvidia control panel power management mode to prefer maximum performance. Disabling Battery Boost in nvidia geforce experience Setting windows power options to high performance I have even installed a fresh windows 10 on a different hard drive and have observed the same result. Has anyone else done this upgrade and had no issues, are there any known fixes, is this card faulty or just not going to work correctly. Thanks

    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.
  3. Hi, I installed a new GTX 980M in a M17X R4 but there's no way to get PEG mode working. First I tried to follow instructions from Lee James Wood (who sold me the card), using the stock A12 BIOS but it didn't work. He stated I shouldn't stay on Windows 10 x64 with Optimus mode because it'll cause issues and probably damage my new GTX card because of erroneous temperature readings, so I have to try harder. I tried with an unlocked A11 BIOS and then following J95's instructions: ...but it didn't go. In a different way. By the time I power on the notebook after reinserting the card back, I obtain a black screen and beeps. I tried the procedure step by step, first by setting in the BIOS the mode to PEG and disabling the integrated graphic card. then I tried by setting the mode to PEG and setting the integrated GFX to auto instead of disabling it. No way: always black screen and beeps. Actually the video cards are in SG mode, and nVidia Optimus seems to work right. I'm not enough into video card tech to judge but mr Wood, who's much more expert than I am, told me that using SG mode the dedicated card signal and management go through the integrated GFX; because of this there's the risk the dedicated card isn't correctly managed, especially regarding temperature readings. Nothing wrong except slower performances. Has anyone a piece of advice for me? Has anyone with a similar hardware configuration managed to use PEG mode? And How? It seems there's no other thread regarding this matter, and that I'm not the only one with this problem. Thanks in advance!

    MSI GT70-0ND GTX675m swap to GTX980m

    Hello guys hoping you can help me out here. I recently picked up a gigabyte p35x v3 cf2 with a gtx980m i also have a msi gt70-0nd with a gtx675m. Unfortunately the msi's video card burnt out about a year ago but it is a much better machine for me. It stays much cooler and has a better screen/touchpad/keyboard. The p35x also gets way to hot and the motherboard has already died on me once, i believe the thermal solution in the gigabyte just cant handle gaming even with a cooling pad. During gaming i would see 95*+ on the cpu and the whole wrist pad gets very hot. My gt70 would only see 80*+ during heavy gaming and i don't need to carry around a cooling pad with it. Anyway i want to swap the videocard over from the p35x to the gt70, has anyone done this with success? I believe i could just flash the vbios with the MSI version avaliable from tech-powerUP. I am wondering about the heatsink, i work as a designer at a business with several CNC-vertical mills so i could fab something up just wondering if anyone has attempted this as it seems every gtx675 out there has burned itself out by now.
