Well, I got my Conroe today and after a fair few hours of tinkering I got it stable at 3520mhz. I'm sure with a bit more playing around and a bit more knowledge I can get this chip a lot higher.<br />
<br />
Heres a screenie of Prime and temps. I'm very happy with the temps so far.<br />
<br />
I've got 1.35v selected in the bios (shows up as 1.304v in cpuz for some reason?), 2.25v on the ram (too much maybe?) and all the other voltage options increased by one notch.<br />
<br />
Can anyone tell me what a safe maximum voltage is for this chip?<br />
<br />
Ta<br />

"safe" maximum voltage would be stock. Anything above that is risky. There's no way to know how much your particular chip will take, and no way to know how much damage any extra voltage is doing. That's part of the risk with overclocking, unfortunately. If the chips could consistently run at a higher voltage and clock rate, they'd come that way from the factory <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /><br />
<br />
A lot of people will likely post that +/- 10% or 20% is 'safe' and while it's true that most people can do this without a problem, it's important to realize that no matter what, if you increase your voltage, you always run a risk of damage to chip.

While I agree with you to a point, the base voltage set by many boards is above the max recommended voltage by intel. In the C2D area its max is what 1.3 according to the box?? but the chip is designed to run at much lower then this like .850+ and in some case's defailt voltage on some boards will be set higher then 1.3.<br><br><div style="margin:20px;margin-top:5px;">

Not realy, as they would much rather sell a lower clocked chip for a set price first then bring out faster chips later as they have always done, I mean they dont manufacture each and every chip differant as that would cost to much, they simply make a slower chip out of the same thing they make the faster chips with, they just disable the extra multi/multi's. Maybe Ive got it all wrong but thats how I look at it.

A lot of companies warranty their ram at voltages set higher than stock.<br><br>
OCZ for example warranties their DDR1 ram up to 2.9v while stock is 2.7.<br><br>
Overvolting can cause damage obviously, but if a company will warranty something to a certain voltage, they must deem this voltage marginally safe.

</div>Indeed - but Intel doesn't (at least, not that I'm aware of). <br />
<br />
So in the case of processors, my point is that anything above what the manufacturer sets can't be definitively labeled as "safe". Again, I'm not saying people shouldn't do it - obviously most of us here run them over stock voltage, most of whom do so to no ill effect - I'm just saying that anything above what the manufacturer warrants is inherently risky.

Hiya Joe <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />, nice OC already there<img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" /> . Dontcha love how fast it is?<img src="/images/smilies/tongue.gif" border="0" alt="" title="Stick Out Tongue" class="inlineimg" /> 2.25v is fine for that ram, I run mine at that with no problems. Alot of serious OC'ers run them higher than that too. Run them lower than that if you can though, lower volts is always better if it can be done. Same for the cpu. I'll probably tinker with bringing down my vdimm shortly too, I think they can do my oc with less. <br />
<br />
As far as cpu vcore, much of that depends on your temps of course, always keep them in check. Maximum level for air is about 1.5v, and like tankguys said there's always a small risk when you OC, more volts more risk. But if your temps are OK, you <u>can</u> go to 1.5v. Me and many many others have actually even run them higher than that. <br />
<br />
IMO, I like to keep an everyday OC on my 6600 to about 1.45. I have no problem with that kind of volts and I'm not worried about it really at all. You'll always get different opinions, some people are just more worried about that extemely small chance something might go wrong. I say go for it!! See what you can max out at with 1.45-1.5, then see if you can run your desired everyday OC (whatever you feel is stable, under your max) with less volts. My <img src="/images/smilies/2cents.gif" border="0" alt="" title="2cents" class="inlineimg" /> on the matter anyway. Or you can do the more conventional way, and inch your way up with speed and vcore, whatever you want. <br />
<br />
Mine can go over 3.6ghz with 1.5vcore. At 3.5ghz though I need quite a bit less vcore, so I run it at 3.5ghz 24/7.

Thanks Roscoe<br />
<br />
Just what I needed, someone with a similiar setup to give me a straight answer <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /> <br />
<br />
I got mine stable now at 3.6 Ghz using 1.425v, 2.25v ram and all the other voltage tweaks up a notch.<br />
<br />
FSB is 450, ram 1:1 4-4-4-12-6-30-10-10-10-10 900mhz. Max temp so far is about 52c (TAT) which is safe as far as I'm concerned<br />
<br />
I'm sure with a bit more tweaking I can bring some of the voltages down, just like you said<br />
<br />
thanks for the info

Prime stable for a while now, not over an hour but this feels pretty stable (able to browse internet whilst priming)<br />
<br />
This chip has a lot more to give <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /> <br />

Nice JoE! You got a pretty good chip there man. If you really wanna know if it's stable though, run the TAT stress on it for awhile. I thought I was stable, cause dual prime along with dual folding, didn't fail even after over 24hrs. But once I started the TAT test I found I wasn't. It would go for awhile, then rig would reboot. It seems like a great stress test to see if you're stable, it stresses the cpu harder than any program (or combo of many progs) I can throw at it. I can be dual core folding + dual prime + internet + movie encode + couple other things, and TAT still stresses the cpu harder and gives higher temps. Even though both cores are at 100%, I guess TAT manages to stress it even more to the limit.<br />
<br />
One thing about that though, while it will <u>really</u> tell you if you're rig is stable, honestly you won't ever (and can't it seems?) stress it that hard anyway. I'm strict on my stability, so I do it anyway, just so I know the cpu can be utterly slammed and not fail. Keep it up man! <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

Cheers Roscoe<br />
<br />
I was thinking about using TAT to test stability........I'll do that now for a few hours.<br />
<br />
How reliable are the temps from TAT? I'm guessing they must be pretty close to spot on<br />
<br />
Ouch! I just tried the TAT test and within a minute the temps were 60c, thats 10c higher than under dual primes. I would have run it for longer but that test seems extreme!

The temps from TAT are <span style="text-decoration:underline;">very</span> reliable, the actual core temp, not measured off the hsf like many progs do. Max limit I still see different opinions. Seems like alot of people say to keep it under 60C if possible. Some people run them higher than that. I think thermal spec from intel says like 80-85C is <span style="text-decoration:underline;">maximum</span> for core temp, and will probably start to throttle and/or crash at these temps, plus it's not too healthy for the cpu. Just because a cpu throttles though, doesn't mean it's going to die, they're pretty tough, not saying it's good for it though.<br><br>
Again though, TAT itself will run it hotter than anything. Mine goes over 60 when doing TAT, otherwise I can't get it to break 50-55 no matter what I throw at it.

Interesting results. I just got an E6600 Week 28 B chip in the other day. I'll be able to run some tests and post results by around Wednesday of next week.

Same here. Dual folding with both cores at 100%, my core temps in TAT are about 49C and 47C, respectively. But when I start up TAT, it can shoot up to slightly over 60C. I really don't think it's anything to worry about short term, to stress test. Other people get the same thing. I've seen quite a few people state that TAT stress test goes well over 70C and even up to 80 or more, for them. But no matter what else they do, their temps are fine. I'm not sure at what point they actually start to throttle though. Personally I wouldn't like them to get over 65 doing the TAT, but that's me, they can take more than that.

Nice OCing Joeking <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile"><br><br>
i wish i could OC mine more but temps are restricting me <img alt="" class="inlineimg" src="/images/smilies/frown.gif" style="border:0px solid;" title="Frown"><br><br>
when will we see 3dmark scoreS?
