So I'm 24/7 stable with my e6600 at 390fsb x 9 = 3.51ghz. I am wondering if i could push it a bit further or would it be unsafe?<br />
<br />
vCore: 1.5125v in the bios, but other programs report 1.47, so i think my mobo undervolts<br />
vMCH: 1.65v<br />
vDIMM: 2.0v <- that's my highest rated voltage<br />
vFSB: 1.40v<br />
PCI-E: 100mhz<br />
PCI: 33.33mhz<br />
Timing: 5-5-5-15 <- lower timings results in unstable system.<br />
<br />
TAT idle temps: 47C-49C<br />
TAT load temps: 58C-60C<br />
ambient temp: ~24C<br />
<br />
Cooling: Tower112 w/74cfm thermaltake fan pushing, rear 120mm exhaust 3 cm from the HS pulling.

I heard from someone that it wouldn't be safe to go over 1.5v vCore with my cpu, is that true? I mean, my temps are still good, and the ambient temps are only going to drop in the upcoming months.

As a fellow E6600 owner, are you noticing a major speed increase with your overclocks? May be a silly question, but I've got mine up to 3ghz and am not really seeing THAT much of a speed difference. I may try out your settings and see how it goes for me. <br />
<br />
Also with Asus mobo, what do the PCI-E numbers mean in the BIOS? I notice you can adjust them but I have no idea what they do.

I actually do see a bit of a increase in certain areas such as openning programs and just raw processing power, of course your benchmarks get higher too. But for most of the day to day operations they are already so fast even major increases in speed are hardly noticable.<br><br>
the pci-e numbers the frequency of your pci-e channel i suppose, i'm not quite sure what it does but it locking them at 100 and 33.33 increases stability.<br><br>
but does anyone else have any opinions on whether i should push this further?

Just OC'd my system to your specs and I'm running nice and stable at about the same temps as you. Have you run 3DMark05 at all? Curious as what your score was.

i get 4000ish in 3dmark06, never ran 05, i would expect you to score much higher with that x1900 cf set up

C2D's have pretty high heat tolerances....but for longevity purposes, I'd keep it at or under 60C. I'd stop where you are.

I just updated from 1405 to 1407, so i'm redoing my oc from scratch, i'll see how far i could go with this one

</div>If you don't lock them down, then everytime you raise the FSB, you raise the bus speed on those as well......and those buses are not as hardy as the FSB. Also, too high speeds on them can fry out any cards in them, and possibly the bus itself. <br />
<br />
As to your voltage question, that would be highly subjective. What is <b>safe</b>? Someone told you that over 1.5 was not safe, but by whos definition and what standards? The max rated voltage according to Intel is approx 1.32.....obviously their definition of safe differs.<br />
<br />
To properly answer your question regarding voltages, one must know not only your cooling (which you told us, high end aftermarket air) and also your expectations and needs for the CPU. If you don't care if the CPU lasts over a year, there are different levels of "safe" than for the person who wants the CPU to last for 3 years, or even 5 years. I would say right now you are in the 1-2 year range at that voltage with those temperatures (with TAT, if it was PC Probe measured temps the CPU would be taking heavy damage). That's a very rough estimate of course, there are no gauruntees. Personally, I would not exceed 1.4v on air unless I was ok with the possibility of needing a new cpu inside of 16 months.

and i will take heed to your two cents. so in other words i should stay where i am if i plan to upgrade every 12-18 months then? bummer, would have like to go to 3.6ghz.
