****OFFICIAL I7 980x HEX CORE OVERCLOCKING THREAD****

Got my 980X yesterday...

980x.JPG


4160MHz stable with NO other bios settings but upping the FSB to 160. This is with HT on aswell. Nothing but FSB changed.
Easiest OC i've ever had.


I'm waiting for new RAM for my Gigabyte UD7 mobo as it dont want to boot. So this OC is on the Asus P6T Deluxe.
I can get 4320MHz stable with extra voltage. And over 4.4GHz with HT off. Hopefully the UD7 will go higher...

Swiftech GTZ CPU block and triple radiator water cooling.

These things happen. Can you share the vcore, qpi voltage and approximate temperature it died at?

It seems a bit odd that the top end of the vid range is coincident with the absolute maximum vcore for intel's 32 nm chips, there was about 0.2V between them for 45nm bloomfield. Also strange that the vid range is unchanged by the the move to 32nm for that matter.
 
not really sure, was pushing for a 4.6ghz clock on a simple water loop
nothing too extreme

temps were in the region of high 70s low 80s using around 1.4 on the qpi for a 2100mhz+ memory overclock.

the chips VID was 1.1v. it needed 1.3v for 4.2ghz

the overclock i was going for was achievable [but intended for benchmarking]. nevertheless, it appears that 1.4 is too much. either that or our ES was quite a fragile example. :confused:

i still maintain that they clock in between C0 and D0 chips

sort of sharing attributes from each revision, hard to explain really.

for instance, they run cool like a D0 but need a little more tickling with the vcore like a C0

best way i can describe it is that it is like clocking an i7 965 C0 chip

i have clocked 3 GTs now

Sorry to hear the news, but my guess is that you killed the memory controller on chip with the 1.4 QPI. I must admit that my gut feeling is that this particular chip was as you say a bit fragile, but by the same token it worrys me as I would have thought they would have been a bit more robust than that. Think I will deffo hold out on a purchase to see how others get on with clocking these - hope this is not the start of a trend.

:p it was an early engineering sample so it was a little different to a retail example.

Actually, I would think that's just as satisfying in it's own way, knowing you pushed it to it's limit. :)

I'm still not convinced by these benchmarks. Unless application threads are created to use all those cores then I don't see this as anything over than a workstation/server chip which makes me wonder where this sits in the market place?

Thanks road-runner your a star :)

WOW! 6ghz on a chip. How on earth did they manage to get it stable at almost 1.9 volts? Surely that would kill the thing.

I do wonder how it didn't fry at 1.89 volts. Mind you he's probably got the chip at some ridiculous sub-zero temperature with the cascade cooling.
