***The Official Core i7 Overclocking Thread***

RE: UD5, F4R (F4J EXT) is a bit slower (but solid) in the ram department than the F4K, but that one has worked for some as well. But it is worth trying the ones I mention. They changed something for the worse in the later betas and official F4, F5A. It would have to be something very special for me to move on from F4J.
 
Is it just me or are the Gigabyte boards generally not as good at OCing? The highest i've seen on here with one of these baords is fornowagains OC and he has a 940, but i still get higher with my 920 on a P6T.
If it was me i'd sell/return the board and get another! I've often found that (ignoring cooling) half the time the board is holding the OC back, not the CPU.

Highest I could get with the P6T was 4ghz - it flat out refused to boot at anything higher.

The UD5 got 4.2 and I suspect would also go higher were it not for temp problems.

Its only the bios needing more work with certain DDR3 speeds which is holding it back right now. GB are struggling with this as they have yet to find the sweet spot.

It can go higher, just don't care to put more than 1.4v through it. Mines not a great chip, needs quite a big vcore increase for 4.2.

With the boards, if anything its the other way round, Gigabyte has a slight edge, most of that will be down to the bios. With the chips IMC the board is far less important than it used to be, now they're all about power regulation, bios and features. You'll see the cheap vanilla boards going just as high soon enough. Keep an eye on the newer boards with digital PWM, see if they get higher baseclocks.

F5c is much better for me. I can now get into Vista with 4050Ghz & very good temps.

However, still not stable and also after reverting back to the default settings after it BSODed cannot now get back into Vista with the same 4050Ghz OC as before which is a little strange.

Hi fornowagain,

I thought you were using bios F5A on yours and found it to be good, at least I thought that is what I read from your posts on xtremesystems forum.

Or do you reckon F4J to be the best ? I am currently using F5A seems ok but I have the double boot issue with it from cold - any ideas?

No mate, I've tried them all except for the latest F5C. Always end up back on the F4J, has the lowest vcore demands for some reason. Not much you can do with the double start, all the F4/5 do it on mine.

Cheers thanks for the confirmation - will try to get F4J.

F5c still not stable. I can sit at 4ghz for a while then it just BSODs with no warning. Going to wait it out until GB get a more stable release for ocing. Stock speeds are fine with F5c rock solid stable but as soon as you put a lot of load on it crashes.
 
Sorry to jump in folks, as you may or may not have scene i'm putting together my i7 build over the weekend.

Will be using the UD4P and i7920 coupled with some CorsairXMS3, DDR3 PC3-10666 3x2gb, I'm just curious as to which Gigabyte BIOS people are recommending at the min? Also is there any major difference in product code/batch number on the i7's? I see on intel's website there is a BXC80601920 and a BX80601920.

Fornowagain, any chance you could send me f4j for the UD5? I have looked through the Bios thread and cannot find it. Email in trust.

Cheers,

Avoid F5D

Just had my first your bios has recovered from a checksum error message and is attempting to restore to an earlier version with F5d!! Its gone back to F2.

Think that is the last time I try the betas for now:eek:
