I have a little question. There iş a laptop with 820m GPU. The graphics are disorted in games. There is no problem with onboard intel graphics. When I run GPU memtest, the test fails. The Ram on the board is H5TC4G63AFR and There are four of them. The problem is I cant provide them. Instead of this Ram model if I use eight H5TQ2G63DFR, Will there be a problem? Or can I use another Ram model? Any help appreciated.

Re: lenovo g710 gpu ram problem
The VBIOS must have the profiles for the new VRAM configuration, and you must change the VRAM strapping resistors to select the correct profile. Better put the same VRAM as originally on the board. You can try first to reball the VRAM instead of replacing it if you can't find it. In any case it could be a dead GPU as well.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

Recently, I have started to encounter a problem with Lenovo E15 Gen 2 models not opening. When you try to open the device, it gives a warning sound and does not display an image, when you apply light pressure on the keyboard, the image appears and works for a while, when you turn it off and on, the same thing happens again. Bios was tried, RAM slots were cleaned and soldered to the legs, the problem still persists. There seems to be a problem with the onboard processors, but since Lenovos glue the processor firmly from the sides, the paths are very damaged when removing it. Has anyone encountered... -
Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise.... -

Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.
I used Lenovo's SmartBeep decoder and it returned error 0284:"TCG-compliant functionality-related error (possibly BIOS code validation failure)"
I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...06-16-2025, 12:06 PM -
Hello, I have a problem with this computer.
After connecting the power supply, the keyboard lights up and the touch bar works, you can click on it and it even illuminates the keyboard. When the fan is turned on, it turns on and off. the processor heats up. I have tried different bios but with no success, the same signs. It doesn't charge the battery either. when starting, it takes 20v and about 0.650a, after some time it drops to 0.350a and 5.2w. Has anyone solved the problem with this model?
Will it be a RAM or CPU problem?
below is the computer details
