NVIDIA GeForce 840M Overclock - Page 2

It gives me an error, so we have to stick with the GPU-Z version. The CMD output:

NVIDIA Firmware Update Utility (Version 5.236)
Simplified Version For OEM Only

Adapter: GeForce 840M (10DE,1341,1025,0867) H:--:NRM S:00,B:03,PCI,D:00,F:00

The display may go *BLANK* on and off for up to 10 seconds during access to the EEPROM depending on your display adapter and output device.

Identifying EEPROM...
Command complete with error, Error code = 0003
Command id:0002 Command: NV_UCODE_CMD_COMMAND_EID failed
Command Status:NV_UCODE_CMD_STS_NONE
Error: NV_UCODE_ERR_CODE_CMD_EID_RD_ERROR
EEPROM ID process failed.

ERROR: Error: Display adapter's EEPROM ID process failed

Hi, do you want a backup? is it?

A backup, and i think it's better to do the modify to your GPU's stock BIOS. Every chip is different, i want to do it for my owen chip. But i have a baseline what will work.

Make a backup first... type nvflash --protectoff and save you bios with gpuz

Ok, i will try it, but only tomorrow. Now i don't have more time for it. Thank you for the help, i will continue it tomorrow.

Make your overclock with msiafterburner or other software, the problem was saving your bios? ok... see you later

With that GPU you need more memory overclocking than you do GPU since that is your largest bottleneck (pending game of course)

Yes, I know, but at the moment my 1185MHz is a little bit unstable. This is why do i want to mod the BIOS abd manage the clocks/voltages vetter

You might inquire at Tech inferno as they are generally much more informed about molding laptop bios's

I'm overclocking it with MSI Afterburner, but only the Core clokcs and Memory clocks are unlocked, the Core is locked in a *** way, 135MHz is the limit. But if I'm playing cs.GO, the Core usage goes up to 99%, and I think I could make a more effective OC like 1350MHz instead of this 1259MHz. And when I try to disable the read block on the card with nvflash, it gives me an error too. But I have an idea. I've installed Ubuntu 14.04 for a reason. And now, I've found a Linux version of NVFLASH. Maybe try that?

*EDIT*
Someone on TechPowerUp found that it isn't working because the BIOS isn't in the card itself, it's in the system BIOS. This is what he said:
"Update:
Figured out why nvflash doesn't work - the VBIOS isn't in the card itself! It is in the main system BIOS. So I got the latest Lenovo BIOS update, extrated the ROM file, pushed it through the PhoenixTool to extract all the segments, found the Nvidia BIOS among all the chaff, added it to libvirt so it gets sideloaded into OVMF via romfile option, aaaaand - it still doesn't work. Initial analysis indicates the reason its not working is that the 860M VBIOS is not quite a standard UEFI BIOS. Normally I would expect to see a 1536 byte header on it, which this appears to not have - but crypto signatures are there as one would expect from the UEFI BIOS. I wonder if PhoenixTool stripped out the header and saved it in a separate file...

Just to make things even more interesting, there are actually 3(!) Nvidia BIOS-es in the system BIOS. It is very easy to deduce, however, which one is the correct one - fire up a Windows LiveCD and download and run GPU-Z. Note the BIOS version number - of the three BIOSes extracted only one will have a matching version number.

Which leaves just one question - whatever happened to the UEFI header for the VBIOS..."
