HELP!! Windows 7 problem - System Check

Hey Guys ! LOOK!



I SUCCEEDED !!!!! WOOOOOOOT


I put in Quotes, what i ve found and what i ve got to do to get it :S
in hopes, that one day , it will help another person :)

Thanks to the xXlAinXx's reply and your discussion,I think I've found how to solve
the problem and it works on my X38 system with GTX550Ti.Now follow me(Based on XP
system).

1. Download the latest driver and extract it.

2. Enter into the "Display.Driver" folder and find the file named "nv4_disp"
(For XP,it is the "nv4_disp".For Win7 ,it is the "nv_disp" )

3.Find the line "[nv_commonBase_addreg]" (For Win7,there are"
[nv_commonBase_addreg__01]" and "[nv_commonBase_addreg__02]")and add
the lines that xXlAinXx mentioned at the end of it.For example,before we tweak it,
the line is:

[nv_commonBase_addreg]
HKR,,Acceleration.Level,%REG_DWORD%,0
HKR,,DevSwitchSuppressMask,%REG_DWORD%,7
HKR,,InstalledDisplayDrivers,%REG_MULTI_SZ%,"nv4_disp"
HKR,,MultiFunctionSupported,%REG_DWORD%,1
HKR,,UseBestResolution,%REG_DWORD%,1


After we tweak it,the line is:

[nv_commonBase_addreg]
HKR,,Acceleration.Level,%REG_DWORD%,0
HKR,,DevSwitchSuppressMask,%REG_DWORD%,7
HKR,,InstalledDisplayDrivers,%REG_MULTI_SZ%,"nv4_disp"
HKR,,MultiFunctionSupported,%REG_DWORD%,1
HKR,,UseBestResolution,%REG_DWORD%,1
HKR,,VarBusLinkWidth,%REG_DWORD%,0x000
HKR,,RmForceEnableGen2,%REG_DWORD%,0x001
HKR,,RMNoGen2,%REG_DWORD%,0x000
HKR,,RmDisableGen2LinkRetraining,%REG_DWORD%,0x000
HKR,,RmForceEnablePcieGenSwitching,%REG_DWORD%,0x000
HKR,,RmOverrideSupportChipsetAspm,%REG_DWORD%,0x000
HKR,,RMDisableGpuASPMFlags,%REG_DWORD%,0x000

4.Save it and exit.

Then reinstall the modified driver.Choose the Custom(Advance) option and then next,
choose the Perform a clean installation option and then next,choose continue when
display the warning.After that reboot your computer.

OK.Now your video card is forced to work on PCIe2.0 mode.You can use the GPU-Z or
CUDA-Z to check the video card's working situation.In my system,the GPU-Z shows
the card working on PCIe 2.0 X16 @ X16 2.0 mode,and the CUDA-Z shows the memory
copy "Host Pinned to Device","Device to Host Pinned" are about 5000 MB/S.So it is
really working on PCIe 2.0 mode.

At last,thanks to xXlAinXx again.

Well, got the same 'problem', with an ASUS P5E, X9650 CPU and GTX480 GPU, running in PCIe 16x ver. 1.1, although it runs ATI cards f.i. 5870 in PCIe 16x
ver. 2.0 . Has to be the X38 chipset.
