Thread Starter 
how I found this stable setting..hmmm? (no, it was not an accident) As sad as this sounds I came to this the hard way, time and testing;

I recently updated my BIOS to the newest P6X58D Premium BIOS and found an engineering copy of the Marvell controller firmware, got a new video card, installed a 6 Gs/s SSD. (my "mv91xx.sys" blue screens have completely disappeared btw). FF a little, and I noticed a slight drop in my usual GFlop values after putting in the SSD so I needed to tweak some things.

So I started 1.32500v QPI and went down in .00625 increments to 1.25000v QPI, and this is where it gets sad;

I ran IBT 2.5 on High, 11 passes throwing out the lowest and averaging the reamianing 10 GFlop scores, keeping an eye on the numbers. each setting was tested twice in this fashion. (yes, ALL of them) I scribbled these numbers in my pocket-sized notepad. AFter writing it all down 2 particular QPI values had a litlle bit higher GFlop average than the others, 1 other had the highest average GFlops, but both IBT runs showed noteworthy lows with the noteworthy highs that also appeared in both of the 10 GFlop scores IBT runs.

All IBT (and LinX) tests were done exactly the same; fresh reboot, open CoreTemp, Open CPU-Z, open IBT set on High, 11 passes, wait for CPU to throttle down then click start. I use IBT because you can do 11 passes and get GFlop scores pretty fast (relatively speakinng). IBT is also used in the official GFlop thread here, so I like to test with it for that reason also

This particular setting in the OP was the 2nd highest overall score average, but also had the tightest GFlop score spread in the 20 IBT passes. I thought this would be the best setting to validate my results using LinX with a fresh reboot. I fully expected that all this would amount to not much, but when the LinX numbers also came back as tight as I ever remember seeing I thought it was worth noting.

Anyway, as you can seee, here is the c omplete 20 pass, completed run, it's interesting to note pass 11 was when I took the screenshot, and pass 14 my monitor hibernated, so I moved my mouse and clicked a couple times. I thought I crashed originally.



Mentat training can be useful sometimes.

If i turn ht off with my OC my gaming fps goes up 3= 10fps depending on the game.

It is also very simple to turn it back on if you need it...
Better Ram and Better Mobos huh? God I love how delusional you are Hokie.

Run maxxmem for us. I need a taste of your memory superiority

Very nice OC, with great temps! Would you mind PM'ing the BIOS settings you used? As I'd like to try it out.

Can you do a 25000 problem to see what you get as well?

A couple nights ago I was tweaking, and got this with HT on, but now I'd like to start playing with HT off and see what kinda results I can get.

I've done 4.2 with HT on, but the temps are in the mid to high 80's, and I haven't played around and tweaked it enough, I wanted to get a stable 4.1 first.
