Max Safe Voltage for an E6300?

[WintersFury]

Hey guys,

I'm cranking up the clocks on a friends computer as well they have no interest in hardware or tweaking and just want to play the games and all.

So well since it's not mine, I don't want to cook the thing or run it at anything overly risky. It's got a TR Ultra 120 on it and is currently doing 2.8GHz at 1.27v or so. But I want to try and get 3.0+ out of it since it seems like it shouldn't be too much of a problem but want to know where to stop the volts.

Thanks!

I wouldnt go over 1.4 for 24/7 use!!

Nice, that gives me a pretty good bit of voltage to work with. I was figuring 1.35ish and I think I'll keep it around there or less just to be safe.

Anyone else, yay or nay to 1.35/1.4?

its a 65nm processor.. you can go over 1.4v.. i think the max is around 1.5-1.6v something along those lines..

1.45 on water or 1.4 on air if u want it to live; had mine deep into the 3ghz on water for gaming when they came out

Holy... Wow... For a stock 1.25v cpu (At least that's what I'm seeing on the net though I think this thing ran over 1.25v stock) that's a pretty big bump from stock.

I'm thinking the 1.35/1.4v will be the best as I don't know how often it'll be cleaned once it leaves here and I don't want to risk cooking it too much.

Its all about 45nm vs 65nm, the E6300 being 65nm is fine up to 1.5v, I ran my E2180 for some times at that voltage. 45nm on the other hand should be kept around 1.4v. So long as you stay under that you will be fine, just keep an eye on temps!

It is generally safe to take the CPU up to 0.5V below the absolute maximum voltage spec. That would be 1.55V for 65nm Core 2 CPUs, so it is safe to go up to 1.5V.

i still think intels rating on its c2q 45nm processors is wrong.. take a look at AMD's 45nm rated max voltage is between 1.5-1.55.. Intel i7 rated max voltage is 1.5v and i havent seen to many people talking about c2q 45nm processors between 1.40-1.50v dying.. which makes me think that the actual max voltage for the c2q 45nm is 1.5v..

I know people who run 65nm WAY past 1.55v also, but I sure am not going to. Best of luck if you do though.

AMD's 45nm process is completely different, as is the design of their CPUs compared to the Core 2 architecture. Similarly, the i7 architecture is also vastly different from the Core architecture. The maximum voltage does not depend only on the process size but also on the specific transistor design, the layout of the CPU, the method of manufacturing, the materials involved, etc. Intel would not set the specifications they do without good reason.

I ran my E6400 at 400 FSB with 1.5V (watercooled) for years without problems.

Intel absolute max voltage per data sheet for the 6300 is 1.55 V. Assuming the boards CPU voltage regulation circuit also meets Intel specs for overshoot of 50mV that leaves a "save" max value of 1.5 volts - if you want to believe Intel. Me personally, I stop at 1.45 and ran one for 2 years at that and the CPU is still running almost 24x7 at 1.375 at a lower OC. But less is better and if you can get your friend a decent OC with lower - do it.

Dont forget to look at tweaking his video card a bit if possible.

yeah i know.. but how many c2q 45nm cores have you seen die between 1.4 and 1.50v? ive yet to hear of any but then again i wouldnt say i was actually searching very hard for that information..

I don't recall any that died, but I have certainly seen chips that have been damaged or experienced degradation due to excessively high voltage. Again, there's a reason Intel sets their spec the way they do.
