Привет. Помогите, мне грустно.
Существует clevo p150em, недавно обновленный с 7970 до 8970 м (от 150 см)
Bios, R.2.0 / 1.02.17EC v3b / 1.02.11EC.
Когда он был установлен 7970 м, в BIOS на линии gpu это было 7970 м. После установки 8970m, NVIDIA пишет вместо 8970m.
Драйверы на 8970m не установлены, либо синий экран, либо ноутбук замерзает. Windows 10 1713.
Я пробовал разные версии драйверов, все равно. Что вы посоветуете?
8970m vbios VER015.041.000.000.044964 BR44964.009 it s DELL?
ps. when I bought 7970m for a place of 670m. At 7970m there was also a problem with the drivers, but I somehow skipped it.
Hello forum, i have a problem.
I own a P370EM it had a 7970m but its not working anymore. I bought a GTX 770M to replace it. But after changing the cards, after POSTing the screen goes white even though the pc boots into windows normally. What may be the issue?

Hi, I have a Clevo P170EM with an AMD 7970M. Last year I tried to change the vBIOS of my 7970M, a friend of my tried to change it because he wanted to ''overlock'' the card. He said no worries I said okay do it, then later on he returned my laptop and bricked both my card and the normal BIOS. I had to repair the laptop trough a repair company in the city. They only could repair the BIOS by doing another BIOS on it. They said to try everything with the card but my laptop wouldn't accept it. The problem: After the Windows 10 installation I installed all the drivers from the manufacters site (http://www.eurocom.com/ec/drivers(226)ec). Including the SSD driver, then I FIRST installed and fully updated the Intel HD Graphics. After that I installed the AMD videocard drivers (crimsons edition), the weird part is, AMD autodetect sees my card and so does Windows. Then the driver ask me to restart my laptop, after restarting the Windows logo appears then the screen goes black with a blinking cursor left upper screen. I believe it has someting to do with the vBIOS of the card and I also believe that the card is not bricked but just wrong BIOS. I asked the manufacter and they say that the card may be bricked, when I ask for the BIOS they would not provide it for free (bastards). I asked for both the motherboard and AMD card BIOS, they said I have to pay for it. Question: Can someone provide information and files for the right vBIOS? I mean the vBIOS that is standard. Greetz, Jamie P.s I have some pictures and screenshot of Windows and the BIOS detecting the graphic card, the weird thing is both OS and BIOS detect the card but when I install the drivers it goes black P.s.s I already tried everything AMD support provided so I have no use for comments like ''Try unistall with DDU'' or try with second monitor etc. As you can see I've disabled the card because when I enable, Windows freezes and screen goes black.
I have a big problem-> I need to undervolt my GPU (MSI 7970M@DELL_BIOS).
I am using this vBIOS: https://www.techpowerup.com/vgabios/132831/dell-hd7970m-2048-120629
Stock VDDC on this GPU is 1.050V and when I changing this one to 0.975 in VBE7 it is ok-> I can save it and flash it. Computer succesfully restarts but when I check modded settings the VDDC is still on 1.050V
I checked if the VBE7 seriously saving the VDDC to vBIOS but it is ok. I have no idead what i need to UV this card (i know it's possible...)
Everything is changing (GPU, MEM MHz) but VDDC can't change.
Please help me ;-)
I've got 2 graphics cards - 7970M's. I believe one card is Revision 1.1 and the other one is Revision 1.2 because it has double row of capacitors as described here: http://forum.notebookreview.com/threads/amd-hd-7970m-revision-through-software.788469/
Laptop is XMG P702 Pro (P170EM). I bought it with 7970M (Rev 1.2) from a guy who said he played a game and laptop just went BSOD. Since then, the card doesn't work properly. Win 8 was installed, I removed it and installed Windows 7 so it's easier to boot in Safe Mode.
Things I have tried so far:
- with XMG BIOS (version 1.02.17)
1) BIOS recognizes the GPU - 7970M
2) Safe Mode works, I see the GPU, if drivers installed it is 7970M, if not, then Standard VGA Graphics Adapter, I can run DDU no problem
3) Windows detects the GPU under Display Adapters as Standard VGA Graphics Adapter
4) I have tried different AMD drivers, some of them install the drivers with no problems in Windows and the GPU shows as 7970M with no warnings or such, some show black screen during installation. Clevo 7970M.zip (believe driver is 22.214.171.124) package from Clevo website installs normally and during Windows loading screen, I see the mouse and after few seconds I see the black screen with top left underscore blinking. I also hear the Windows welcome sound. (Tested with Teamviewer autostart from my PC, I see the desktop, but it's like Minecraft, whenever I drag mouse around, it creates some blocks)
- with latest PREMA BIOS (version 1.02.17PM v2)
1) After installing Clevo 7970M.zip driver, laptop boots to Windows and 7970M shows Code 43 in Device Manager.
2) Safe Mode works, DDU too, 7970M shows up when drivers installed, Standard VGA Graphics Adapter when not installed.
Now with the second 7970M... Revision 1.1.
1) doesn't pass POST screen with old BIOS
2) doesn't pass POST screen with PREMA BIOS (I press F2 and it shows as selected, but just hangs on it at that moment)
3) laptop starts beeping and shutdowns
Note: 7970M has been tested in Alienware 17 R1, BIOS shows 7970M, Windows show 7970M, drivers installed, all good.
Question: does Rev. 1.1 work in P170EM? If so, could it be wrong VBIOS?
P.S. After checking out physically 7970M Rev. 1.2, I found everything to be messy around the double row of capacitors, especially one bridge so I decided to remove it and make everything clean, but later I found in the first link I posted, there should actually be a bridge? Acted too fast, stupid... (I have quality soldering station, hot air station and microscope). I didn't examine the GPU at first, I tried all the methods above, didn't work, then I proceeded with desoldering the bridge and trying again the GPU. Didn't work either. I can resolder the bridge if necessary?
I can give you pictures from the GPU's, VBIOS or anything else that you might think could be useful.
If it turns out 7970M Rev. 1.1 needs another VBIOS, I was thinking of getting EEPROM Programmer, desoldering the GPU BIOS chip and flashing new (compatible) one to it. Ideas?
P.S. #2 if anyone could drop a hint on what to physically check on the 7970M Rev. 1.2, that would be great. I googled the black screen problem and could it be that voltage regulator is blown? I don't mind resoldering another one.
