Maximum Vcore?

post #1 of 8
Thread Starter 
For an E8400? I was reading a magazine today where they were telling people to put 1.55v through it in order to achieve a 4.0ghz overclock. However, for a 45nm chip, isn't this dangerous?

What are the possibly effects of running this vcore 24/7?

Killing it most likely in a matter of DAYS. The max vcore for these 45nm is 1.3625v as specified by Intel. Of coarse some people decide to go on to 1.45v but thats all on their own decision and theres a high chance the CPU will have a short life. Those 45nm's needing 1.55v for 4Ghz are ES (engineering samples) which are the very first processors to come off the assembly line for testing purposes, so far 99% of the time production CPUs (as Intel calls them) which are the ones we buy on the net or retail stores, overclock much much better as Intel as incorporated fixes in them before mass producing them to sell to public. Reviews said my E7200 needed 1.52v for 4Ghz and all it needs is 1.392v.

I have read a ton of arguements that say 1.3625v and also others that state 1.45v, now I know that you shouldn't exceed 1.45v. I personally have run my E8400s around 1.39v-1.41v for more than a month without any issues. Personally though if you can't afford to replace/rma it don't go past 1.3625.

EDIT: There are many threads about this posted, you should go do a search you will find plenty of discussions on it.

I think 1.36 is the limit. I would read this thread for lulz. People were frying their chips putting 1.45 vcore into them. http://www.overclock.net/intel-cpus/...d-out-yay.html Paul sums it up nicely too http://www.overclock.net/intel-cpus/...ml#post3379638

Well, they have a readers question area, so I will write to them quoting some of this information. The magazine in question is Custom PC. This is what they said:

"...more importantly, the E8200 overclocks like a loon. We easily pushed it up to 4.08ghz using a 1.55v vcore and an FSB of 510mhz (2.04ghz effective)..."

EDIT: It was actually a E8200, does this make a difference?

Only in that the E8200 has a lower multiplier.

They are gonna fry it with 1.55 vcore.

I'd be nervous putting 1.55v into my Q6600 nevermind a 45nm..
