Whats wrong here? - Page 2

post #11 of 25
Raising the PCI-E freq has a good affect on boosting performance for the GPU. I am not sure if this is due to a boost in bandwidth to the gpu or the bandwidth of the SB mobo link.. but either way it works to our advantage.

I have found that on most mobo's i have had, going much beyond ~114mhz with the PCI-E freq has little positive effects.. sometimes actually deteriorating your score's some. I run ~105-110mhz for 24/7 use and ~110-114mhz for benching. Raising the speed will require a touch more SBv to stabilize as well.

*Also use a qwk bench like AM3 to test the affects of raising/lowering the PCI-E freq.

where do i get AM3?

bah.. nevermind. It wont run on a 64bit OS anyhow.. didnt see that before


If you have Crysis you can D/L the Crysis Benchmark tool. Its very qwk and very configurable.

I do have the benchmark tool - is it acurate though? I mean I ran it two times and results varied by about an average of 5FPS

Hmm. Cant comment on the accuracy of it.. I guess its 3d mark or bust if the results vary by that much.


Raising the pci-e freq 5mhz for me netted a 400point increase .. it also allowed me to run over 730mhz core clock for the gpu, stable..though not by much.

oh wow okay that might explain why i get artifacting at 630 core

are there any risks of incresing the pci e frequency? the cooling on my mobo is pretty terrible.

I think its the background applications killing your scores..

Try doing a msconfig and getting rid of all those startup programs.

Also try something like this http://www.blackviper.com/WinVista/servicecfg.htm

(Don't forget about defrag, running ccleaner atleast once a week, etc.)
29 processes?!
wow, I have 84 right now with only a few background apps going 0_0
(yeah I disabled most of the useless startup stuff already)

There are risks involved in upping the PCI-E freq, YES.

If you go to high with out raising the SBv, most of the time, you will not be able to load Windows off of a sata HDD. Other than that, permanent damage can occur from very high PCI-E clocks.. [ie- 117+mhz] I would only go that high for testing purposes.. not for gaming or reliable 24/7 use.

are you OC'ing with the shader clock linked? If so unlink it.. the GTS has a higher shader clock than the GT does.. You should be able to raise your GPu core clock to at least 700mhz on stock volts. *Have you locked the gpu fan at 100% yet?

I increased my PCI lane clocks but get this:

Its reading in BIOS as PCIex3, windows is only showing me lane 3 is filled... my card is in the top slot, labeled lane 1! What gives?


I have my GPU fan locked at 85% for now - i can hear it if it goes above 88%. temps are at a mild 70*C under full load

how do i unlink it? im using NVIDIA CONTROL panel to OC right now.. and ATI Tool to test

I read somewhere Riva Tuner does not work in vista 64
