I'm currently using the ASUS P5E 0702 BIOS, but have flashed my mobo to the Rampage BIOS from before but switched back because I was getting too many BSOD's and driver conflicts. With that BIOS I reached 445x8, but it wasn't prime stable, but I got a couple of runs of 3dMark06 and PCMark 05 out of it though. With the 0603 P5E BIOS, I reached 440x8. The thing that i recognized, was that the Rampage BIOS has less Vdroop than the plain vanilla P5E BIOS. Anyway, that seems off-topic now, cuz i wanna stick to my current BIOS without getting those BSOD's again and corrupting my Window's installation again.

For 24/7 use, I have my CPU running at 400x8. But yesterday I was bored and decided to start testing my mobo/cpu threshold again. This time I wanted to find a stable setting, and did not want to do suicide runs of benchmarks lol. I set my FSB to 425x8. My BIOS settings are as follows:

VCORE Voltage: 1.39375
CPU PLL Voltage: 2.02 (I still have no idea what the hell this is)
FSB Termination Voltage: 1.50 (Can't go more than this with stock BIOS)
DRAM Voltage: 2.20
North Bridge Voltage: 1.71 (Can't go more than 1.75 with stock BIOS)
South Bridge Voltage: 1.175
Loadline Calibration: Enabled
CPU GTL Reference: 0.63x (Can't use .67x with stock BIOS)
North Bridge GTL Reference: 0.67x
SB 1.5V Voltage: 1.75 V

And all the options like spread spectrum and C1E and Speedstep are disabled. This yielded me stable settings, but I think I probably went overboard with the voltages. Here's a screenshot of my testing yesterday. Anyone care to chime in? My specs are listed in my profile. Any input will be aprreciated.

BTW here are my current 24/7 Settings (for 400x8) because they are not updated in my sig.

CORE Voltage: 1.3125
CPU PLL Voltage: 1.68
FSB Termination Voltage: 1.38
DRAM Voltage: 2.10
North Bridge Voltage: 1.43
South Bridge Voltage: Auto
Loadline Calibration: Enabled
CPU GTL Reference: Auto
North Bridge GTL Reference: Auto
SB 1.5V Voltage: Auto

These settings are perfectly stable. Compared to what i recently entered I think you know why I'm concerned I might have went overboard :twitch: :confused:

Come on, I know there are other Yorkfield overclockers out there. :(

I haven't really pushed mine too far. I usually stick to the same 400x2

For now, my 24/7 settings are sufficient, but I'm just prepping for som of the newer titles like Clear Sky and Far Cry 2 to come out because I use a 24" monitor

That's pretty much the same conclusion I came to. I am currently only running a 19" but my double deuce just got delivered today!

tRas@12 ram 1:1

I notice your ram is 1:1 and your tRas is at 12. Is the ram set 1:1 always? If so then your ram probably can't take higher clocks with tRas at 12; try setting tRas to 15[ 5-5-5-15] so your ram can take higher clocks if its set 1:1.

EDIT:

BTW When I first got my q9450 I had to have my actual cpu voltage at about 1.36-1.38v just to be stable at 3.6Ghz, but over time that decreased to about 1.328v as it is now. I also found a FSB wall at 450Mhz which as far as I read happens to a lot of people :( Also I read around the net and there is a question as to how high a vtt voltage will fry these chips. [vtt==FSB terminatin voltage I think] After reading that others had to pump in lots of vtt and vNorthbridge to get a higher clock I decided to try a higher vtt, and I found I could go as high as 475Mhz FSB. While stress testing I was reading around the net about vtt, and what I found scared me so much that I changed vtt back to stock and going back to being perfectly safe at 450Mhz FSB. If you apply to much vtt then overtime the chip will die :cry: Funny enough though I think that short stint with to much vtt actually helped my chip break in so that I could lower the voltages afterwards :roll:

Your North Bridge is WAY too high, back that thing down to 1.5. CPU PLL voltage is supposed to quiet the frequencies or something, I keep mine at 1.8 for my Wolfdale.
