Amazing Temperature 66C at 4GHz !

DavyBoy, I'm reasonably sure youre temperature limited more than anything else. But as I can't see anywhere that you've posted your load temperatures. it's hard to say for certain.




Into the lower speed bundles ? I doubt theres many out there that wont hit 3.8




Vid does not indicate overclocking potential, it never has done. A low vid tends to correlate with clocking high, but it's in no sense a cause and effect relationship

@john, it could be that I am temp limited, but there is no denying it that this chip is a bad sample..

I was told that the chips that don't make the grade for 4GHz bundles get used in the pre built systems like the Titan Goliath that is clocked to 3.4GHz...

Like you said John, there wouldn't be many D0's that couldn't do 3.8GHz..

Though with the earlier batches, from what I have seen on various forums most of those chips would run happily at 4GHz and beyond..

@Gaidin, like John stated, just because a chip has a low VID, that doesn't mean that it will be a great clocker.. you also have to take things like the IMC into account with i7's, if a chip has a poor IMC then it isn't likely to clock very well...

The thing that is bothering me the most, is the fact that I sent back a chip that could boot into windows @ 4.4GHz on air, and I have been given a chip back that struggles to boot into Windows @ 4GHz..

The last one would do 4GHz without breaking a sweat, and the temps were acceptable even under my old Zalman..

This replacement has higher temps when it is clocked lower, is using less Vcore and QPI voltage, and has a TRUE cooling it... I thought it was the base of my TRUE that might be causing high temps, so I installed my other one only to get the exact same temps, so I fitted the Zalman to see if that made any difference, and the temps were even higher!!!

I recon once I got my last chip under water, I could have gotten a stable o/c @ 4.2 to 4.4GHz quite easily, also, with that chip I was able to tighten my RAM timings to 8-7-7-21-1T, but this one can't even run stable with 8-8-8-24-1T, I have to use the stock timings for it to be stable, I can't even use 1T command rate, because it BSOD's as soon as I start priming...

I hope OcUK start selling chips that are guaranteed to clock to 4GHz/4.2GHz at some point like they used to with the Q6600's, I would definitely be willing to spend a little bit extra cash to get a decent clocking chip, and I am sure there would be plenty of other people willing to do the same as well..
 
Issue with memory I believe, related to a heatsink clip.

I think ocuk are on very thin ice here, there is no reason why they should be unable to return the processor you rma'd. If they've put it in a new machine, for someone who paid for new components, they should get a slap and are probably liable for civil action if the guy who ended up with your chip ever finds out. That's very shady indeed.

I suggest logging a formal complaint, the management should be rather more competant.

edited to look less hostile towards the beloved ocuk
