Your Asus P5N-D 750i and Q6600 Overclocks

Anyone got this combo and what are they getting on their Q6600 overclocks? Just intertested as I max out at 3.2ghz 100 Stable (400x8), however can run benchmarks at 3.42ghz (380x9), and can boot into windows at 3.6ghz and run Super-Pi, however, it's not bench stable. So, I have the following:

Q6600 Vid is 1.325v

Q6600 @ 3.2ghz (1600FSB 400x8) 100% Stable Prime95 and OTTCV2.0
CPU Voltage = 1.53125v In BIOS (CPUZ = 1.488v, 1.456v VDROOP)
HT Voltage = 1.48v
NB Voltage = 1.50v
SB Voltage = 1.52v

Q6600 @ 3.42ghz (1520FSB 380x9) Benchmark Stable
CPU Voltage = 1.58125v In BIOS (CPUZ = 1.536v, 1.5025v VDROOP)
HT Voltage = 1.52v
NB Voltage = 1.54v
SB Voltage = 1.52v

Q6600 @ 3.6ghz (1600FSB 400x9) Windows Stable, Super-PI Stable ONLY
CPU Voltage = 1.58125v In BIOS (CPUZ = 1.536v, 1.5025v VDROOP)
HT Voltage = 1.52v
NB Voltage = 1.54v
SB Voltage = 1.52v

I'd love to know what you lot are getting on this board and you overclocks...

They seem to be very few and far between on these forums.

And that's crazy vcore for 3.2ghz and 3.42ghz.

Yeah just thought I'd give it a go as the only other forum I use is Futuremark and that's so quiet these days.

Think the mad CPU voltage is because of the high vid of 1.325v... but yeah, the voltage for 3.42ghz is just benching as that's way too high even for me... 24/7 and I use it as a folding machine at night so I need 100% reliable...

Pretty annoyed really as I know that this CPU will go 3.6ghz even 3.8ghz I';ve had windows boot up at, but just think this board is crap at clocking... plus with all the ram as well... it's taking me 2.1v on the ram to make sure it's stable, if I leave the ram at 1.8v, then the CPU voerclock becomes flaky for some reason... odd...

The memory is probably specced at 2.1v anyway (if it's the Quad Channel Platinum XTC 8gb kit). You may need 2.15v for running 4 sticks.

Hi,have Q6600 running (vid 1.225) @3.6 on this board 8 hours prime stable,(only 2 gig if memory though) with vcore at 1.42 in bios giving 1.37 nominal which drops to 1.32 under load.NB/SB/HT voltages are 1.46/1.54/1.46,memory voltage set at 2.1.Think there`s more in this chip but the board isn`t up to it as speedfan reports a lovely drop in 3.3v reading as the vcore is increased (assuming I haven`t got the wrong end of the stick and the psu`s struggling): :rolleyes:

Cheers for posting fella... much appreciated. Well, looks like I just have a crap chip then... removed my 4gb RAM leaving just 4GB (2x2gb) chips in, and clocked to 3.6ghz, nope, BSOD once and BSOD in windows unless I put ludicrous voltage through it, so it must just be down to the chip, looks like you have a nice one there fella!
