I use Prime95 Small FFT's for testing CPU stability. 6 Hours is plenty. I use Blend for system/mem stability and I use Large FFT's for FSB/Chipset stability. You should not worry about Large FFT's since your running lower than 450MHz FSB speeds. Also, I use memtest for Windows for mem.

Oh... ok I thought I was doing the right thing by using ibt... damn...

I've got Prime95 here but I was planing to use it in the end... I guess I'll start now. In this case are you saying that I should leave it running for 6 hours every time I increase the FSB? lol that will take a while...

Can you tell me when I should use Blend? I use memtest too phew biggrin.gif

Finished with 3.2Ghz but now I am not sure if I should be so confident knowing that ibt is rubish...

Found the Static tRead Value and Static tRead Phase Adjust. I've put both on 10.

I'll try to run @ 3.2Ghz again but this time with Prime95. I'm just not sure for how long...

IBT is rubish in my opinion.

Really, you can run Prime95 small FFT's for 15 - 20 minutes at a time to get an indication. Then up CPU speed/Voltage and try again. And when you feel you've found your limit, then you can run it for 6 hours +.

Really, Blend should be ran first at a lower CPU multi and your final target FSB. the FSB/mem speed you wish to get stable at your max clock. This way, you'll leave out your CPU as a problem. You will only test system stability and mem stability. Then if stable, up the CPU multi again, if it fails you will know for certain it is the CPU, and that you'll need more V-core

Leave Phase adjust at Auto. Static tRead is the only one you should set to manual

It didn't boot. It went past memory check then it restarted.

I am going back to 3.2Ghz and I'll make sure it's running well before I continue...

Also, by leaving IBT you can do a higher overclock. As I've said, IBT is heating CPU's to totally unrealistic and insane levels, but are really no good for detecting errors.

Prime 95 small FFT's often run 10C lower max temp VS IBT, so you overclocking headroom will increase. If you're Prime95 stable (Small FFT's and Blend, and especially Blend) then you're 100% stable for everything else. This has been pretty much proven the last 10 years, or God knows how long Prime95 has been out, used for stability testing

425FSB should be absolutely no problem in that board. So I'm guessing it's your mem.


Edit:

If so, and you cannot down the mem speed, or if loosening timings don't work, then you can go for 378FSB x9

Cool, I am running right now on small FFT. I'll do Blend next.

This will sound very silly but I just have to go to Options, Torture Test and select the Small FFT or Blend right?

I just want to make sure I am doing the right this as it seems to be much lighter on the system.

That is correct Make sure you have Prime95 for 4 CPU cores It will show 4 threads.

Finished testing after 40 minutes (20 small FFT and 20 Blend).

During the Small FFT there was one error on core (worker) #2. It said: "FATAL ERROR: Rounding was 0.5, expected less than 0.4."

Blend went fine all the way...

Running small FFT again for 15 mins.
