What the max safe voltage for E8200/E8400/E8500 cpu's

[pastymuncher]

crank the suckers up, its a cheap cpu - enjoy the speed.
its warranted and will probably last forever (as long as you need it)

so long as its properly cooled...............

however some ppl will always get a duff one that blows.

i have a e8200 at 3.92ghz - 1.45v.

£115 is a lot of money to some people. Advising people to "crank the suckers up" is irresponsible. These things do not like voltage. If it fails due to excessive voltage you will not get it replaced under warranty.

beat me to it . But on another front nobody paid attention the the old 65nm chips when overclockig. I Put 1.8v through my q6600 and it still works fine,

Just out of interest Pasty - had you modded your mobo to reduce vDroop/drop? Has anyone else here suffered degradation?

 

[Jumping]

if you want a stable - no problem trouble free pc (for the most part), dont overclock anything!

freedom of choice.......................

if you want to overclock - get the best cooler you can, and crank it up big styleeeeee

Even people with Liquid Nitrogen cooling takes care and dont just CRANK it up. I seriously hope that no one new to overclocking listens to your advice.

Do the e8XX cpu's OC to around 4GHz with the stock cooler?

So if you put any of that through you're processor its still covered by warrenty???

EDIT: ffallic I wouldn't recomend the stock cooler, its pretty small and useless, it idles high if I remember correctly. Better off buying a tuniq tower (£35) or an artic cooling freezer 7 pro (£18)

Was merely curious

I will never again own anything as cumbersome asw a tuniq, but probably would get something like the ACF7.

Just that I saw an OEM e8400 for a good price, and very nearly snapped it up.

Then I realised, I am only going to get to really use it for two weeks before being without it a month, and by that point, prices would have come down.

I'd say 1.4 is the maximum safe

The maximum VID is set per chip at the factory. And the VID is not the vcore, if you are worried about maximums go by the values printed on the box as above. Only thing is, how are they going to tell you've killed it with a little too much vcore?

Specs say the absolute maximum voltage that it can survive with possible degradation is 1.45v and then only for transient spikes.

So exactly what kind of bad advice have been giving in this thread? It doesn't matter if the OP didn't say he/she was new to overclocking or not the fact is that any one reading your "advice" could risk killing their CPU's unnecessarly. Any kind of overclocking can kill your CPU but a sure fire way of killing your CPU is to CRANK the power up without thinking what you are doing.

 

[Jumping]

To bad there was no lines to read between...and I wasn't the only one who thought your advice was careless and shouldn't have been posted.

But there is no point in trying to convince you any way so take and have a good weekend.

I have now but had'nt then. The vdroop is abysmal on my board, 1.4v in the bios gives you 1.34 under load. Did the vdroop pencil mod and got it up to 1.392v. It was getting silly when you have to increase voltage in the bios to 1.55v to get 1.48 actual (E6600). There was a big thing about degredation/deaths over at XS. One bloke had two Wolfdales die at 1.45v.

I've had my E8400 running 4.5GHz at 1.525V since I got it (about 8-10 weeks). It is water cooled and don't see real core temperatures over 50C. There is no real evidence of electron migration damage to E8x00 series CPUs, but there is no doubt several users have had very strange experiences with CPUs losing overclocks and then, in some cases, not even holding stock speeds.

I'm fully aware of the risks of running my CPU at higher than stock voltages, but for me it's worth it for the experience, if nothing else.

Until we know for sure, I think it's very wise for most users to err on the side of caution and stick to 1.4V in BIOS until better evidence comes along to prove once and for all what the 'safe' limit actually is. It's also possibly worth pointing out that many motherboards have an automatic over-voltage feature that should be taken into consideration when working with voltages. These features are often called voltage stabilization or anti-Vdroop functions and they can add as much as 0.1V to the CPU voltage. If you think you're running 1.4V and you have the anti-Vdroop switched on, you could really be running 1.5V.

My E8400 has been sitting pretty and rock solid for over 2 months now at 4Ghz and 1.29v. With all this talk of degradation I'm glad I seem to have one which does 4Ghz at relatively low voltage.

Got another E8400 in the media PC downstairs but that one's never been run at anything other than stock so I don't know what its potential is.

Thats a damn fine cpu you have there.
