I'm in modding mood :D

We (me and a friend of mine, G73JW owner) just put a 6970m in the G73JW to see whether it works. The system POSTed and loaded Windows, but unfortunately the screen stayed blank :(

Some background infromation about this whole story... When I exchanged the CPU of this machine a couple of weeks ago I decided to take a look at the GPU as well, as the system was already disassembled. (Note, it's a real pain to take apart this machine... totally unlike the AW systems... you have to tear it down completely, take out the mobo and then turn it around to get access to GPU/CPU...)

Anyway, the GPU has nothing to do with an MXM-card... except for the connector which seems to be the same (at least physically, I have no idea whether it's the same electronically)... but see yourself:

attachment.php?attachmentid=636&d=1304782784

attachment.php?attachmentid=635&d=1304782782

As you can see, the connector is physically identical, but the die is positioned differently than on a standard card... As the G73JH has the GPU at the MXM-conform place we got a heatink of the JH model. After some cutting and grinding it did fit the 6970m. The problem was that you can't fix the card with screws since the holes of the G73JW 460m are at totally different places... but that's nothing a little bit duct tape cant fix :D The important thing is that the heatsink can be screwed on very well.

But well, like I said, it didn't work... a couple of hours work for nothing. So we had to disassemble the system one more time to put the 460m back, lol.

I knew the chance of the 6970m working was small... but since the G73JH (5870m) can run with a MSI 5870m as well, I thought it's worth a try.

Maybe it's only an issue with a hardware ID, I have no idea... like I said, POST was fine, system booted, but screen stayed black.

If anyone of you have an idea to get it working, let me know!

There are two more pictures as attachment which show the 6970m on the mobo and in the system, if you're interested... just as "proof" :D

Love it Svl7, nice job working on modding... not sure what made the pc just display a black screen. Did you guys try vga mode and taking out all video drivers, seems like if you got windows to boot there's a chance. You obviously have the will, so there's probably a way.

Yeah, uninstalled all drivers in advance.. and I even tried to get the picture on an external screen (just for the case that I messed up with the display connector...). Too bad it didn't work. I'm not sure whether it's usual that windows boots when the GPU doesn't get recognized by the system...

Did you try to boot in safe mode? or the screen remains black there as well?

Hmm, actually no, didn't think of this... but there wasn't even a boot logo showing up, not a single pixel :D I guess it wouldn't make a difference. But next time I run into similar problems I'll give it a try.

Yeah if you can't boot into safe mode means that the BIOS is not recognizing the card. If VBIOS was the problem then you should be able to at least boot into safe mode but under normal mode you shouldn't be able to install drivers

It wouldn't have POSTed if it was a bios problem. Seems to be driver related if the Windows logo looked fine and not distorted. Safe mode might be worth trying. Also, try removing the cmos battery and clearing it to reset the system when putting the 6970M in it.

Yeah, POST, but black screen, not a single pixel... no boot logo, nothing.

weird, I would at least expect it to show Windows' boot logo since it POSTed... later on it should either crash or the screen go blank

Hmm, I'm not sure, maybe Windows was set to "no GUI boot"... but I don't think so since there wasn't even the Asus logo showing up.

So, since I had no more ideas so far to get the 470m working, I put the 6970m back and made sure every cable was plugged in correctly, especially the display connector.

Still the same symptoms, no picture at all, not even the Asus logo. Pretty crazy... with the 470m I can go to the BIOS, boot DOS from a USB drive and use nvflash etc... it just doesn't boot Windows. But with the 6970m I don't have a picture at all, but it seems to boot Windows, it's driving me crazy!!!

Yep, definitely, tested it in the M15x (only goes to 2d clocks for whatever reason, but that's another story) but it works.

You could try Win reinstall with 6970M in. Come on, I know you want it. :D

So, right now even the 470M doesn't work?

So you said the 6970M in a M15x will stay at 2D clocks and won't go to 3D... Maybe it detects no gpu usage etc and doesn't scale itself up due to that. Can you flash the vbios with RBE and set the 2D clocks to the 3D speeds? So the card runs 3D speeds all the time no matter what? Or are you limited to 2D voltage.

No sorry, the 470m works only with 2d clocks in the M15x, but the card is definitely in working order (that the card runs only in 2d mode in the M15x is a known issue). The 6970m works still perfectly in the M15x :D

I'll try to get the 470m working in the M15x as well, but it has been tried already by Inap and didn't work so far.

But it's weird that I have a picture with the 470m in the G73 and with the 6970m not even the boot screen shows up.

Yeah this is very weird if a gtx 260 can work in a G50V-T then i don't know why it can't work with a G73JW stupid Asus always trying to make things complicated. Put that 6970 in that M15x i agree with unreal you know you want all that power!!! Too bad the GTX 470 doesn't work with our machines that well it would of been a great benchmark card to compare to the 6970.

Well, the 6970m seems to work in the JH, but there are still some problems...

I only tested it in the JW, and unfortunately I wasn't successful. Maybe it would work when flashing the JH BIOS on the JW, but that's too crazy, lol.

Well you can always get a spare one to be just in case. How many machines do you own? You sound just like me lol. But aren't you flashing the VBIOS after you extract it from gpuz? You should try what your suggesting just take your time with it if your take determined though. What problems are there for 6970 in the JH? I would love to try that but i really am not good with opening machines usually it ends up either going to the depot, or a tech comes out and fixes it lolz.

I only own an Alienware M15x, hahaha. All the stuff I tried with the JW was on the machine of a friend of mine, who was kind enough to let me rip apart his precious system, lol :D I was talking about the system BIOS, not the vbios. The JH and JW have similar mobos, so the JW may work with the JH BIOS, but that's a crazy idea. I only thought about it because the 6970m seems to work in the JH, but not in the JW, even though they are almost identical hardware.wise.

But I can't just flash the JH BIOS on the JW, it's not my system and I don't want to brick it. :)

Some guy at NBR finally tried to put the 6970m in his JH and it works, but it won't go to 3d clocks without manipulating the clocks and the performance seems to be less than it should be.

Disassembling the G73 is not really easy, especially when you do it for the first couple of times. You'll need to disconnect all cables from the mobo, remove an incredible amount of screws, (about 4 different types, no counting the special GPU screws) and take out the mobo from the system to get access to the GPU. The heatsink needs some modding, otherwise it won't fit on the 6970m.

- A lot of work, and nothing I'd recommend doing withouth ESD protection and a steady hand. It's easy to mess up with all those fragile cables, but if you're working concentrated it's totally possible to exchange the GPU, but it's really time-consuming.

Sorry for not answering man my father died, he was in a lot of pain been somewhat of a difficult time. Yeah man the G73JH is a real pain to change the parts even to put a SSD in the drive bay sucks you gotta reverse the caddy it's so stupid and they always give cappy seagate for drives not like Scorpio black WD drives best hard drives not hating seagate either but man thank god i bought me some new external cause that Segate 1TB Go Flex was going to die on me good thing i got it fixed though and i know i digress. Before in the past the G50 series was so much easier to work on they want to make it so hard to replace everything and you gotta have a steady hand because some of those cables can really mess up the machine that's how happened when my friend was pasting mine didn't go so well which resulted in a 2 month wait to fix it. Happy at least the new G743D has a higher illumance, black levels and brightness over all, and contrast the G73 has horrible brightness but great black levels but whatever. Well hopefully with the new G74 you can try it out i wish they went back too ATI those cheap bastards looked like the G73JH was really the best bang for your buck. What's new with you? Got any games to reconmend? I really got bored with gaming for the summer lol. And also it's only good to buy one of these Asus from people in good conditon cause it's just not worth it to buy something that is manufactured so cheaply and not to mention the warranty lol.

My condolences to you as well, @freedomofthedarkendheart .

The G74 got the card soldered on to the mobo, you won't belive it... but it's true, a 560m directly on the mobo... only Asus can do such things.

There's not much time for gaming atm, I should be learning for the exams, haven't tried any new games recently.

      Was wondering if the 3 pipe heatsink i have for my 6970m that died, would work on a 6990m if i upgraded?
       
      trying to figure out so i can order. Speedy responses are much appreciated
    • By svl7
      AMDs professional mobile GPUs (FirePro M Series) use the same hardware as their gaming equivalent (Mobility Radeon HD Series)
       
      The difference lies in the VBIOS and in the specialized driver. This allows to simply change a 6970m into a FirePro M8900 by simply flashing the appropriate VBIOS and installing the corresponding driver:
      (UPDATE: This also works with the 6990m, see the update at the end of the post)

      The advantage of the FirePro card lies in the better CAD and DCC performance, optimized OpenGL support, OpenCL features and AMD Eyefinity technology.
       
      In short: The card gets optimized for professional applications instead of games. A 6970m is very well capable of CAD work and a M8900 can still play games, but their performance is optimized for other tasks, and this can make quite a difference. A game uses a GPU differently than CAD software. For example you don't need a high frame rate when designing something with CAD software, but it's crucial that the rendering of your work is accurate and detailed.
       
      So if you have a 6970m and need to use professional software once in a while you might want to give this a try. I haven't installed any CAD software on my system at the moment, but the driver seems to work properly, haven't seen any issues so far.The procedure doesn't take long, you only need to flash the VBIOS, uninstall your gaming driver and install the professional one.
       
      You can use the M8900 driver of the Dell Precision M6600 workstation, you'll find it at the Dell drivers page. Maybe you find a more recent driver on the AMD homepage.
      Here are some screenshots of the Catalyst Pro Control Center, you'll probably notice some features which aren't available with the Radeon HD cards:

       
      I've done this with my Sapphire 6970m, it'll definitely work with the Dell 6970m as well and it's save to assume that this is true for the Clevo/Eurocom version too.
      Since there are some changes in hardware IDs you'll need to force the flash.
       
      NOTE:
      This should work just as well when your system has a FirePro M8900 and you want to optimize the gaming performance - simply flash the 6970m VBIOS and install the regular driver and you're done.
      The Dell 6970m VBIOS can be found in this post.
       
      Also a big thanks to @Star Forge for providing the VBIOS of the FirePro M8900!!
       
      Here's a 3dMark Vantage run with after applying the soft mod to the 6970m, everything at stock, also in the CPCC. Not too bad imo, same pretty much the same as the stock run I did when I got the 6970m in April.
      Would be interesting to see some gaming comparisions... but I haven't installed any games atm.

       
      EDIT: For M17x r3 users: You need to modify the driver, otherwise it won't install here the instruction, a big thanks goes to @devillucifer for investigating this problem and finding a solution.
      When I come around to do so I'll post a link to a modified driver so you don't have to modify them yourself.
       
      Detailed guide for flashing the VBIOS:
       
       
      UPDATE:
      This also works with the 6990m. Note that the M8900 VBIOS has the same clock speeds as the 6970m, so the 6990m is actually underclocked with this VBIOS. You can easily overclock it with software or modify the clocks of the VBIOS before flashing, so that you're back at 6990m speeds. But even at standard clocks the 6990m performs better than the M8900 or 6970m, the card has 120 additional shaders which will bring a little performance boost as you can see in the screenshot below, I about 1000 points more on the GPU score compared to the 6970m flashed with the M8900 VBIOS (at the same clocks).

      IMPORTANT: The 6970m is not officially supported by Dell. Upgrading to this card may void your warranty. The 6970m is a powerful card, it will draw more power and produce more heat. This card can significantly improve the performance of your system, however, the long-term effects of running this card in a M15x are currently unknown, but it works great so far.
       
      Cards that are known to work:
       
      The card Dell uses in the M17x R3: This has only been tested for a short while so far, but it seems to work perfectly fine. Credits go to Rogue-OP and iloveb00bs, the first guys who tried to put a 6970m in a M15x.  
      -DP/HDMI works, confirmed by Strigae, fan control works
      It seems you need to install the M17x R3 drivers first before you can get the official AMD drivers. I guess installing for example the modded 11.4 will work as well.

      Dell Part nr. is: V9XKH.Good luck when ordering one from Dell, depending on where you live and what kind of rep you get on the phone they might not want to sell you the card as it isn’t officially available for your system. Call again in this case, or if you know someone with a M17x R3 let him order the card for you.
       
      6970m from MXM-upgrade.com: Works great, but no fan control. The fans are constantly at a high speed, but not completely at full full speed. For now you’ll need to manually control the fans with HWinfo32.  
      -DP/HDMI works. Sound through HDMI works when you install the Dell 6970m vbios and the M17x R3 HDMI audio driver. Here are the instructions for this. Card can now be ordered for the M15x from mxm-upgrade.
       
      Clevo (and resellers) 6970m: The card from Clevo and resellers (Eurocom etc.) works as well, but  make sure you get a version of the card which has holes for the back plate! Some of these cards have the screw holes for mounting the heatsink soldered on which makes it impossible to use the Dell backplate, and since Clevo uses slightly smaller screws than Dell you can’t simply put your heatsink on such a card. Contact your dealer in advance to make sure you get a card which doesn’t have the screw holes soldered to the PCB, otherwise you’ll have to remove it (which is difficult) or use some smaller screws on the heatsink.  
      For all these cards the heatsink of the M15x fits perfectly. No modification needed.
      Cards from other vendors / manufacturers may work as well. If you got a different 6970m running in your M15x let me know and I’ll upgrade the list.
       
      Things to do before swapping the cards:
       
      Download the drivers. This modded 11.5 should work, click on “MobilityMod Windows 7/Vista” in the linked thread. Also get GPU-Z for monitoring your video card and verifying it, Trixx, for under- and overclocking and in case you haven’t got a Dell card also HWinfo32 (I recommend getting it anyway since it is a great system monitoring tool) Make sure you have thermal paste, maybe some new thermal pads as well as something to clean the heatsink (e.g. isoproply alcohol) and some cloths around.  I also highly recommend using a grounded ESD-mat and a wristband. Know what you’re doing. You need to partially disassemble your machine to get to the GPU. Prepare yourself thoroughly, check out my little guide. In case you need more information, there’s also the M15x service manual, as well as the teardown video. It can be helpful to write down all the steps in advance when you’re doing this for the first time.  
      The upgrading procedure:
      Then (after reassembling your system), boot, install the drivers and reboot. Make sure the fans are running. Open GPU-Z and verify your card and the clocks. It should look more or less like this. Default 3D clocks are 680/900MHz (core/memory) and 150/100MHz when idling. Make sure PowerPlay is enabled in the Catalyst Control Center. Also make sure Stealth Mode is deactivated.

      Check your temperatures. Idle temps should be 40-50°C, but this also depends on your ambient temperature . While gaming or doing something similar GPU-intense the system will run significantly hotter, 70-80°C, maybe a bit higher.
       
      Note: By lifting the back of your system a bit (for example with a book) you can improve the airflow in the system. This can really help lowering the temps.
       
      The back plate problem:
      The retention bracket of the 6970m has a different size than the regular M15x cards (260m, 5850m etc.)When your card doesn’t come with this x-plate you need to take the one you have on your old GPU, but this one won’t fit properly. Nevertheless it works, even if it covers some resistors on the back of the card. Make sure you’re not shorting anything. Usually the back plate has an insulating black plastic pad on it, this will work. However, if your x-plate doesn’t have this pad on it, you must cover it with some thin, insulating tape.

      Here you can see the problem, in the first picture I marked the are which gets covered by the backplate and in the second picture the highlighted area shows where the plate should be.


       
      The space beneath the card becomes pretty tight, but it works. My advice is contacting your dealer before buying the card and asking whether he can provide the correct x-plate. (In case he tells you that you should use the one from your old card tell him it has a different size.)
       
      Power consumption:
      The power draw of the card is probably about 75-100W. I run this card together with an i7 920xm in my M15x and it works fine. Nevertheless you need to be careful, as the PSU of the M15x is only rated 150W. When doing some 3dM11 runs with both GPU and CPU overclocked I measured about 160-170W current draw from my system during the combined test. You really need to be careful when running this card, especially when you have an extreme processor (920/940xm). Pushing both GPU and CPU can (and will) bring the PSU to its limits (and above).
      Some numbers about the power draw when playing games, everything on stocks:
      Black Ops Zombies (everything on max): ~ 130-140W
      Portal 2 (everything on max): ~110-125W
      Medal of Honor (everything on max) ~140-150W
      Crysis 2 (set to “Hardcore) ~ 140-150W
      The device I use for measuring the power draw has an accuracy of about ± 10W.
       
      Fan control: In case you have a card which makes your fans running at a high speed all the time you will need to use HWinfo32 to automatically (or if you prefer, manually) control the fan speed.
      It’s possible to create a fan control look-up table and let HWinfo32 automatically control the fan speed by temperature.

      1. Click on the fan symbol2. Click on “Custom Auto” 3. Choose the temperature sensor diode which you want to use as reference.4. Set the desired speeds/temperatures according to your needs.
      Do this for both GPU and CPU, ignore GPU2 fan. I recommend using the hottest GPU diode (usually MemIO).A big thanks to Mumak, the developer of this fantastic tool. Here you can find the official Alienware fan control thread in case you find a bug or need to know more.
      Warning: Adjusting the fan speed can be dangerous!! Always keep an eye on your temps and never forget to adjust the values before doing something CPU or GPU intense (in case you control them manually)
       
      Possible problems and solutions:
      Unable to install drivers. Solution: Try a different driver. Also contact your vendor, maybe he knows a specific one that works. Idle clocks are 250/900 instead of 100/150. Solution: Check your display settings and make sure only your internal notebook monitor is selected. 250/900 are the idle clocks when you’re connected to an external monitor (or when your display settings are got messed up, probably driver related) The GPU temps are crazy high! Solution: Repaste. You probably did a bad job with the thermal paste. Also make sure your system is dust-free and that the heatsink sits properly and is making contact (also check the pads where the memory modules touch the heatsink). While idling the GPU clocks change from 2d to 3d clocks and back all couple of seconds. Solution: This behaviour can be caused by the M17x r3 6970m driver (A00). Get the latest AMD driver and you should be fine. If you have this problem with a different driver try another driver version.

      Hello.
      I know this could be quite old , but I'm trying to install a GTX660M 2GB GDRR5 in my ASUS ROG G73JW , hope to be able to make it work.
      The reference chart is this:
      80.07.39.00.0F
      I got to ride with the heatsink and modified G73JH laptop starts but gives an error of VBIOS , must understand that flash the VBIOS new graphics card .
      Has anyone tried to put a GTX660M 2GB in this notebook ?
      Can this be done ?
      I read all the post 2012 on changing GTX660M GTX460M to 1GB, but I wonder if you can put a 2GB and if there is modified for her VBIOS .
      Greetings and thanks.

      Hi.
      I have been stupid enough to flash my MXM card with a bios with the wrong ID.
      I'm not sure why this happened as i modified a allready working 6990M bios and only turned down the core clock from 715 to 680. Somehow doing this changed the ID and I now have ATIFlash stating "no adapter found".
      I've read a article made by a user on this forum by the username svl7 - Recovering a notebook GPU from a bad flash
      Hopefyllu this user is still active as I would really want to know what programmer he used, and where he got it.
      Or let me buy a working chip with the M8900 680/900 Hynix bios on it.
      Also read some post about shorting Pin 1 to 8 to bypass the flashchip, but that did not work. May be this is just for desktop cards.
      Really hope @svl7 sees this or maybe someone who knows him can relay this message.
      In advanced, thanks!
      Best regards
      Liquidqtip, the dude running on Intel HD3000 because of stupidity...
