What program is the most reliable for testing stability in Overclocking?

Title pretty much says it all, i was just wondering what program I should be using to test if i get stable overclocks.
Thanks

 

What kind of overclock?

If you're overclocking the CPU and have 4GB or more RAM, then 5/20 runs of IntelBurntest work very well as it also tests the RAM- handy for SetPLL'ers. If you don't have 4GB RAM, IBT won't be very stressful so use Prime95 instead. It will lag the system. I said 5/20 runs because 20 runs with each increase is not practical because it takes too long- just do 5 and increase until you crash. Then back down and use 20 to confirm.

If you're overclocking the GPU, you can use OCCT, it has an artifact scanner so you can set and forget while testing. ATiTool is old school and is less stressful then OCCT with an artifact scanner. Use it if you're afraid of OCCT's heavy stress.
3DMark isn't a very good stability test though- that is why you have so many edge of stability, extremely high clock scores being submitted and shown off.

 

Thanks for the reply
I was looking at cpu and gpu overclocks... should of made that more clear.
with regards to SetPLL, does changing the timings of the ram increase the chance to overclock the system higher? my current m11x r2 i7 is stable at 166 so i might give it a go and was wondering if this would help the chances of getting a higher overclock.

 

It helps if you are limited by the RAM. Some i7s are limited by voltage or BCLK and just can't go any further with an SPD mod though. Try SetPLL anyway.

 

ok so after using MSI Afterburner, ive got my core clock to 560 and its still stable. Im just using OCCT to run for 10 mins every 10 MHz i increase it by, and i just did a 30 minute run at 560. temperature peaks at 55, then fans kick and average temp is about 49.
I havnt increased the memory clock, and ive only increased the shader clock to allow for higher core clocks. should i be increasing them all together? or just one at a time?
Should i be running the tests for longer? and is there anyway to disable the monitoring period?
sorry for all the questions :|

 

OK so im assuming im doing something wrong here, my core clock is now at 585 and its "stable". I am testing with OCCT for 10 minutes and the temperature is below 50 and its not crashing. Is it normal to have a core clock this high?
This is an R2 btw.

 

I just remembered: You need to right click OCCT and select the nVidia graphics option in the "Run with Graphics Processor" menu. Whitelisting OCCT doesn't seem to work so it will run with the Intel GMA. You will know if it's running on the 335M by observing the frame the test runs at: If it's 45-60FPS, then it's running on the 335M. OCCT might not be running on the 335M at all.

You can increase shader clock and core separately. Keep them linked if you can't be bothered to find the absolute limit. They're usually very close to each other anyway. You should run the test for as long as possible. 4hrs is plenty.

You can't disable the monitoring period.

585mhz is a good overclock for a 335M but see above.

Can you use GPUZ to monitor the clockspeed during a load? It's inside the sensors tab. It should stay at the desired clockspeed. If it crashes however, it will stay at low power 3D clocks, 405, 810 324 core, shader memory until the next reboot. This is important as it indicates unstable clockspeeds and higher overclocks won't apply, meaning a lot of time can be wasted for an unstable overclock.

Sorry about the OCCT mess, I haven't overclocked my GPU in a while.

 

oh... yeah i knew something was wrong, i was getting an average 5 fps
ive right clicked it and done what you said, now its time to overclock!
thanks for the help
( i cant rep u anymore :| )

 

Ok so now I have a new problem :\
With my current clocks I am completely stable in OCCT, however, about 20 seconds into 3dmark 06, the driver crashes. Given that OCCT is a more stressful test, how does that work?
