SOS nvidia 650M GT 2GB GDDR5 strange problem


Recommended Posts

Hi all,

I have a problem with my HP envy dv6 i7 3630QM, nvidia GT 650m 2 GB GDDR5 after using nvidia inspector I think.

These pictures were taken without any gaming. As you can see, Intel HD has some peaks up to 1350MHz when the default clock is at 650MHz (card broken?)

This laptop has Optimus tech and it used to work properly but now, the nvidia card is "always working". I tried to -forcepstate:0,16 but nothing change. Sometimes the nvidia card broke and I need to restart the pc.

I've formatted my pc and stills the same. Actually nvidia inspector seems to be bugged because my default memory clock is 1000MHz and the program shows 2000MHz

I didnt try any overvalue with inspector before this happens.

Any idea guys? Thanks in advance.

Sorry for my english, I tried to do my best without a translator.

I'm sorry to posting here but i also have a strange problem, but can't open a new thread. Please move this comment to the proper place! THANKS :)

Hello!

I've bought a budget Lenovo Y500 (i7 3630qm, gt 650m sli, 16gb) 2nd hand for mobile gaming. I'm pretty satisfied with it but have strange low texture "bugs" in special games like TW: Rome 2, Fallout 4, etc...

Tried to change like driver version, tricking with nvidia inspector, ingame settings etc...Installed GPU-Z to realize that the 2 VGA-s running on 2 different vBios versions:

- 1st card: 80.07.27.00.33

-2nd 80.07.27.00.3A

Bit of surfing found official Lenovo vBios update. Which i installed without issues. Restart, than the 1st one changing to 80.07.27.00.3a but no sli. After few minutes this 3a version "changing" back to the original (.33). Actualy i dont care the numbers but i would like to use my rigs full "potential" with decent textures... Strange, i have no idea.

Also wondered unlocking bios to solve the previous problem but i dont have permission to download from techinferno forum (lack of comments/posts).

Could you help/advise/explain about low qual. texture problem, possible solution for vBios changing please?

Thanks in advance,

ps: feel free to ask for explain/screenshots/extra infos. sorry for bad the english

Re# REalized that Texture and version problems are 2 different things. Lets skip the texture thingy for a future task.

After flashing vbios, my 1st VGA EEPROM is out of reach. GPU-Z see normally both cards, but the 1st's EEPROM cant be readed modified, nor nvflash --protectoff command doesnt work. Actualy i cant do nothing with it. Right now im trying to fLASH my BIOS, but already using 2.04 unmodded... Somewhere i read something about flashing bios also change the 1st GPU's firmware. If it's not working i'm all out of ideas....

Advice?

Thanks

RE#2 I hope it will help you if you have the same issue. [sOLVED]

- Backflash BIOS to 2.02

- Flash to 2.04

- Flash 2nd VGA to the same like 1st

- Full Clear Nvidia drivers

- Clean install all drivers

- Problem solved, 2nd VGA ready to OC, 1st still stucked on factory parameters but SLi working finally.
