5GHz+

I did 4.6Ghz on i7 920 d0 once (only for 10 minutes) before revert back to 4.0Ghz because of temperature is crazy too high and had to use more vcore voltages on the 4.6Ghz overclock.
 
i975 @ 5.262ghz 1M Pi run:



E8600 @ 5.4ghz 32M Pi run:



Those clocks were only stable enough for pi runs.

The E8600 clock below is fully 24/7 stable @ 5.1ghz:



This clock for the i975 is the highest stable 24/7 clock i have got so far @ 4.7ghz. Still working on getting it to 5ghz ;)

nope, only been to 3.5 and my mobo wouldn't let it go any further because it couldn't post past those clocks :P

that was on an e6750, which I am sort of disapointed with, I know people that gone 4GHz and beyond with them
 
Nice clocks kitfit!! What setup/cooling were you running to achieve those? Seem great clocks for the voltages!

Best I got my E8500 too was 4.7GHz I think, but best stable was 4.6. Needed quite a hike in voltage to achieve that so ran 4.4 most of the time :)
 
24/7 5ghz overclocks should be possible in the new year with the i9 processors but not easy with the current lineup.

The complete setup for the E8600 is in the link in my sig.

The i975 was done on a Classified E760 with G-Skill Perfect Storm ram.
All clocks are under phase cooling.
 
Something like an Atom, but with a proper FSB and multi, would be a great overclocker. If, of course, the frequency was all you cared about.
 
Got my 920 8345B260 to 4.881 on water at 10 degC

More tweaking may get me higher.....;)
 
Those clocks are extremely impressive kitfit!!!

4.7GHz 24/7 is nuts!

My highest OC so far with my rig has been 4.7GHz, although this was only a CPUZ validation, I never did any stress testing, my highest stable o/c is 4.4GHz..

This stupid UD5 is the only thing that's holding me back tbh, it is near impossible to get anything more than 222 Bclk when overclocking via the BIOS, I had to use SetFSB to push it beyond this when I did 4.7GHz..

Are these on air cooler or water custom build setup ? These are very good temperature of no more than 75C with 8 hyper-threading enabled davyboy!
 
Been to 4.5ghz with my little 920 D0. Temps were getting a little high even though voltage wasn't excessive. Using a corsair H50 with HT on. That was using my reaper ram and failed all stress testing - so I gave up. I found a little later that one stick is duff so i've swapped it out for some spare gold 1333 and been back to 4.4. Once friday is done with I should have some time to see where I can go, 5ghz into windows from cpu-z validation will be nice although I doubt I'll dare load it for long using the H50.....
 
I'm pretty sure the Bloodrage has the 222Bclk limit as well capriboy, which means unless you have a 950, or 975EE you're not going to hit 5GHz anytime soon.

You can hardmod the board though to allow higher Bclk, but the size of the resistors you need to move on the board are extremely small, so unless you are good with a soldering iron, I wouldn't advise performing the mod.

Here's a link to the hardmod I'm referring to..

Foxconn Bloodrage PCIe and Bclk mod

Cheers mate, your right about the bclk limit - already got the link in me favourites ;)

I won't solder surface mount resistors with an iron but I still have some friends inthe trade with hot air re-work stations who could do this with there eyes closed. I'll prob go back for 4.4 odd until my reaper comes back from rma as I don't think this gold will keep up.

Iirc my 4.5 was 215 x 21 although long term I'd prefer turbo off.
 
Not done it with my own kit yet... but given a hand on some LN2 clocks.

I'm pretty confident my Q9550 will get there or very close on a better board when its had its time... despite the high VID its atleast windows bootable as far as my current board can run its FSB - I've had it well over 4.5gig just boot stable.
