I just wanted to share my OC results for both 8800 gt and 9600 gt systems that I have. I built the 9600gt system

for my Friend, and wanted to compare my 8800gt system with the new

9600gt System. Both machines are of Similar configuration except for

the GPU. Here are the results:


System Profile:
Q6600 at 3.4ghz
P5K Deluxe Mobo


8800gt System (Quad-Fusion)
3DMark06: 14541


XFX 8800gt
Stock: 640/1600/900
Max Stable OC: 730/1825/1050
Accelero S1 Rev.2 w/ 120mm fan
Temp>> Idle:38c Load: 47c


9600gt System (Magnus-Machine)
3DMark06: 13312


XFX 9600gt
Stock: 650/1600/900
Max Stable OC: 821/2105/1050
Thermalright HR-03 GT w/ 92mm Fan
Temp>> Idle:33c Load: 46c


8800gt System (Quad-Fusion)  3DMark06: 14541


9600gt System (Magnus-Machine) 3DMark06: 13312

  Only Configuration Differences between the two systems were:
8800gt powered by Rosewill Xtreme 750w, CPU cooled by Zalman 9700NT, Antec 900 Case
9600gt powered by PC Power & Cooling Silencer 610W, CPU cooled by Thermalright Ultra-120 eXtreme with Scythe 110cfm fan, Raidmax Smilodon Case

Just curious...what is your Super Pi 1M time?


 I got 17.237s for Super Pi 1M... i guess it is good enough for Q6600 @ 3000 MHZ

Finally found the

solution !!!

I ran Super Pi 32M under stock settings, however it

failed.  This lead me to think that it

was rather a OS/Program issue than a stable overclock issue.  So I started searching for Vista Super Pi


The windows vista

services that affect Super Pi are,

1) Windows Audio

Service (this for sure)

2) Themes

3) Aeroglass


By turning these off, I was able to run and complete Super

Pi v1.5 32M test.

1) To turn off  Windows  Audio  Service

 ( start> run> services.msc, find

Windows Audio on the list , double click and stop it ) Turning off

"Windows  Audio  Endpoint  Builder" is not necessary unless you

encounter problem.

2) To turn off Themes

 ( start> run> services.msc, find

Themes on the list , double click and stop it ) this will also make you turn

off tune up theme extension.

3) Aeroglass

automatically turns off  by turning

of themes. (you can check it by right clicking on

desktop>Personalize>Window Color and Appearance>Color Scheme )


Another way to

disable Audio service:

To disable sound just for SuperPI and then quickly turn it

on. Create two .bat files on the desktop


net stop "AudioSrv"



net start "AudioSrv"


I found that it is not necessary to run the program as an

administrator or Windows XP SP2 Compatibility mode. But I tried both ways, it


I also found a Super PI 

front-end called Hyper PI

The author claims it is pure Super PI 1.5 MOD XS and it is

customized for multi-core CPU's: " Run multiple instances of SPI (one

for each processor) and configure the priority of the process easily (without

Task Manager). Take a snapshot of all instances at anytime with only one click!"

I personally wasn't able to download it becasue of some server problem.

So I now

declare that my Overclock is stable !!!

Also to note:
Round off was selected on Prime95...& I ran the small ffts test
But priority was set to 1.. From another forum i got the suggestion to set the priority to "10"
Should I run again with Worker thread priority 10 ???

I have an overclocked Q6600 (3.0ghz, 9x333) on Asus P5k deluxe (0603)

It ran stable on Prime95 v25.5 (4 threads 100% load, small fft for more than 12hours)

But fails just one instance (approx 25 % load) of Super Pi v1.5 32M test

It completed 16K, 32K, 64K, 128K, 256K, 512K, 1M, 2M, 4M

16K: completed in 00.179s

4M: completed in 1m 37.124s

8M: failed after 3m 19.413s Loop 21

16M: failed 5m 41.531s Loop17

32M: failed in 6m 18.938s Loop9

All of them one instance runs, and also times vary slightly for different runs..

Memory: 4 x 1 gb Crucial Ballistix Tracer 800mhz (4-4-4-12) FSB>DRAM, 5:6 (333:400)

Os: Vista Ulimate 32bit (3.3gb Ram)

PSU : Rosewell 750W

Load: 56c, Idle: 38c (Zalman 9700NT)

Vcore: Bios: 1.3125v

Vcore Idle: 1.2480v

Vcore Load: 1.2320v

Is my system stable since it passes Prime95 (4Threads 100%) ?

Why is it failing just one instance of Super Pi v1.5 @ 25%load ???
