When using Orthos, I was only running the small FFTs test.

Also, i'm have some inconsistencies regarding temps. CoreTemp, Asus Probe 2 and SpeedFan record pretty low temps of around 26/27C for the CPU and about 31-33C for the cores but Intels Thermal Analysis Tool records the cores as anything between 35C and 45C. Which one should I regard as more accurate?

Finally, I decided to start from scratch with the clock settings and have been using Clunk's P5K addon as a marker. I'm currently at a FSB of 380MHz and the only other settings I have changed is pcie to 100, enabled dampner, set ram timings to 4-4-4-12 and dram voltage to 2.1v which are the details printed on the modules. I've also disabled spread spectrum and the settings in CPU configuration. I'm gonna test things then try take it up in incriments of 5 on the FSB then start to raise the vcore, pll, nb, sb voltages if need be.

Thanks for the continued help.


Now that you mention it, I had to run orthos as admin (right click shortcut, run as admin) to get it to work - but that was with my dual core CPUs. With a Quad you want to use Prime 25.6 is the latest one. Make sure you ram is running at 800 at those timings. The ram is spec'd for DDR2800 @ 4-4-4-12 so with your overclock you memory might be well OC'd and 4-4-4-12 might not work. So make sure which ever divider your memory is at (and ram speed) is not too far OC'd.


With a quad dont use Orthos or Intel TAT - use Realtemp for temperatures and Prime 25.6.
