Whats the record?

Hi there peeps, been looking at some overclocked computers - 5.0GHZ +, but can anyone tell me the world record for overclocking, is it somthing crazy like 7.0GHZ
thanks

Didn't AMD break the 8Ghz barrier late last year?

Damm, thats awesome!

That was my initial thought when I saw these, but there is a slight dampener...

From what i understand to get to these speeds, they have to disable every core except one... AND then disable all the extraneous CPU functions... So it may be an incredible speed, but it isnt a very usable computer

To be fair, these extreme speed runs are generally cooled using liquid nitrogen so even if the chips were fully usable, keeping them cool for any length of time would be highly impractical and/or VERY expensive.

Hit the speed for a superpi run and a cpuz screenshot and validation that's about it.

Mostly under ln2 with ht and cores disabled usually running a single stick of memory.

.iirc it was a celeron of some form that held the record for quite some time with ~7-8ghz.

its still ranked no. 4, 8.3ghz

as said above already. no way can these be used day to day, but still kind of interesting just from speed point of view

Thats the one!!

Probably due to some of those early dual core chips have quite a low stock FSB and high stock multiplier, iirc the Pentium D 805 I had (still have, its somewhere!) came with a 20x multiplier, was quite straight forward to get to 4ghz

wow, so whats the record for overclocking with just normal water, also, if you are running high MHZ at around 60.C will this last along time?

pgi947 · 27 Oct 2012 at 14:32

Should be fine provided you aren't having to use a silly high voltage to get to said speed.

With SB, a decent clocker, you'd easily manage 5-5.3ghz 24/7 while staying under 1.5v. With a 2600K I could manage 5.1ghz at around 1.46v, temps peaking around 50-55c under normal load, high 60's under synthetic stress.

thanks, so for example:
i5 2500k = 5.0GHZ
