Mate, check your ACTUAL voltages, not what you set it to?
Sorry just trying to be clear.
Maybe the bios is giving a different "actual" vcore. I'm sorry feel well bad now recommending you change your bios (504 is definately a known dud though)

Some interesting BIOS settings there, will try those when i get home, especially the GTL settings, i wanted to set these, but info is low on them, but GTL makes a huge difference with the CPU apparently.
Thinking some of the 'Auto' settings are changing about cuasing the higher temps.
Yeh, my CPU is down to copper pretty much at edges, must've been very concave, has a real polish to it now, spent a long time using just 1200 grit. The heatsink i didn't touch, was pre-lapped (it seemed) with a smooth polish to it, but yeh, some are designed wierd to fit concave CPU's or vice versa. I put the thermal grease evenly on both surfaces, so if when i remove it, it's moist in the middle, but around outer CPU seems to be set, that's clearly a seating issue. The CPU is lapped about as good as it gets, must be the fan.
Hernaldo: Nah, that's my actual voltages too, 1.4625, i dropped it from 1.475 last night, still booted and ran prime. Heat doesn't drop, i can keep dropping voltage, before couldn't get below 1.4875. Well wierd. Passed Small FFT's last night but the same core failed again on worker thread 2 (round off checking, maybe not a big issue?).
Tempted to buy a new HSF, but shelled out £60 for mine and my dad's ones. Ultra 120/tuniq probably best, but they look so cheap and crap (i'm funny like that).

Actually, i wonder if my temps are reading wrong, i hit 71C on small FFT's, the heat from the CPU fan wasn't even warm, but i've taken it off 4 times now and re-applied the paste,the screw head's are becoming frayed eek!. I'm going to see if it goes up when i bump up the FSB, because it behaves compeltely different to what it did a week ago, makes more heat, uses less voltage, one core doesn't like FFT's lol.
Tempted to just give this to my dad and see if he'll go halfs with me for a nehalem or something, or gimme £60 for the chip (it's lapped, impossible to sell).

managed to pick up a secondhand Q6600 G0 from Olly here on the forums, given it a good shake out on P95 over night.
click me for a really big results piccie
settled on 3690 so far, but it's getting a tad toasty so i might well change rads & switch to a PA120.3 before i go any further.

My heatsink isn't flat i don't think, but my CPU is lapped and now is...whoops. I really can't be arsed to reseat it a 5th time, i'm running out of thermal grease lol! Also i dunno how long those screws will last, the screwdriver is slipping now.
That VID is amazing. i've found a guy with even higher than mine now, 1.35v! Though he managed 3.6ghz. Very odd, really think my BIOS needs sorting.
Strange how your voltage alters depending on load,etc. Mine stays the same regalrdless, doesn't budge.

They look naff though and are stupidly big! Hmm, heard the Noctua are good. Basically money isn't an object cos i'm a bit miffed with the heat thing. The CPU i've lapped twice with 1200 grit, for couple of hours, it's perfect, though haven't gone quite into the copper, just slightly at edges.
I just can't figure out why my temps are 4-5C higher, got the temp logs to show it. I reckon the fan isn't seated tight enough. The metal bracket was near impossible to screw in before, now it bends in like elastic. I'll check the temps when i get home. If they are ~ 37 idle, i'll take that. 39C/40C, i'm beating crap into the heatsink with a hammer.
Sod it, i heard those Apex watercooling systems are good, i'll just research that, though sounds complex.

How does the Thermalright Ultra look naff and the Noctua not
they look near identical 
If money is no object you really shouldn’t be considering air cooling!
Didn't say the noctua looked any better 
Anyway, may not have to, if i mess about with the voltages i've seen in other BIO's, which at the moment are set on auto, might solve my problem. I'm guessing swapping BIOS's around could lead to those auto settings going haywire, a few degrees temp rise for no reason and my required voltage dropping a few notches must mean somethings changed in BIOS.
I'm looking at water cooling, seems a waste on my chip though lol. Seen kits like the coolermaster aquagate for like £60. But the Zalman Reserator looks nice @ £140. The amount this PC is tallying up, i coulda got an alienware haha, because @ £860, it's still only mid-range this.

The zalman reserator is only for quiet running not good cooling and the coolermaster aquagate is just plain rubbish!!
Im really loosing track of what you are going on about in this thread, but this is for sure..
As far as mb voltages are concerned only vcore and possibly vdimm need to be changed NO other voltages need to be messed with.
The P5K Premium will happily run a quad to 480FSB with nothing other than the cpu voltage adjusted. Many people on here that run this board can vouch for this, me included!
Dude I will say it again, to progress you overclock any further you simply need to up the vcore, if temps don’t allow that you need to look for a better cooling solution.
It’s as simple as that
I can understand that your struggling a bit, but you must stop running around in circles and reading to deep into minute fluctuation in temp and the like.

The point is mine will never ever get that no matter what parts i buy, cos Sc** shafted me, so it's down to tweaking things in order to boost it.
I wanna mess with the other voltages because my BIOS is playing up, sometimes it won't save and exit, just freezes. It's changed something, it's dropped the voltage i need for OC considerably but to contradict that is upping my temps by a huge amount at the same time. Thats why im running around in circles when my temps go up by 20C at will without me doing a thing.

Yip.. have to agree with Hesky... main point is your vcore isn't high enough.. just put 1.525/1.55 through it and see where you can get, unless you put full load on the cores, it shouldnt be too hot.
On your BIOS: Try reflashing to the same bios.. it's possible something went wrong with the first flash? - have seen a few comments from people having to flash more than once to get a result.

True i guess, voltage (unlike last week) seems to have no bearing on my temps anymore, could probably whack 1.6v and see no change, it's that wierd. I'll see how much it can take. It's been so wierd i haven't pushed it because of the temps, before i was going on 1.5125v, now i need like 1.4625 for the same clocks,.... it's the same OC profile.
Yeh, i've gone from my original BIOS to 504, then 404, then back to 504. Think it's save to say it's gone wrong along the way lol. will try it when i get home.
Got my MSI P35 Neo2-FR Intel P35 board last week and was able to get my Q6600 finally past 3ghz.
Got it running at 3.6ghz but it crapped out on me after an hour or so, have it running at 3.3ghz now which is what i was after and temps dont seem that bad 45ish idle and 50-53 after a session of gaming.

Assuming you're using a stock cooler, because that idle temp shouldn't be.
I'm (after a few people here will tell you) struggling with temps since my BIOS starting being a nob, but i'm still at 39C idle @ 3.4ghz, which is hotter than most.
Gaming doesn't count, mine runs crysis in the 40's. Most modern games barely use the CPU, infact Crysis uses hardly any, like 5%. Under a stress test your temps will be a lot higher, though really, people saying about Prime95, i get a core always failing on it, but you will NEVER, EVER, EVER have your CPU under that much stress in real-life, the fact it fails on little round-up tests, when in real-life the CPU corrects itself on this makes it a ridiculous test, but proves the CPU to be totally stable. I might stick with OCCT in future.
Well I managed to get 3.8 stable on small ffts last night for about an hour and a quarter (when I turned it off), but the temps were pretty high. It hit 77 on cores 0 and 1 at times, but settled around 73. I had to put vcore up to 1.45 to hit this clock, from 1.35 on 3.6. Funny thing was that at 9x422, it bluescreened after about 35mins, but at 8x475 it lasted over an hour.
With these temps, I'm thinking that either I need to let the as5 settle in more, or or I've got a cpu and/or heatsink that are not flat! I was definitely expecting it to stay cooler with the vcore at 1.45! Well I'll see how it goes at 3.8 over the next few days, and if the temps don't drop I may get a lapping kit. I'm thinking that if I'm stable at 3.8 and 1.45, I may be able to hit 4.0 if I can get the temps under control. Maybe 3.8 will be my limit on air, and I've always been too chicken to go for watercooling.
