Haswell Overclock Thread

It's the EK DCP 4.0.

As far as I know, it's not the loop.
Last time I threw a GPU under water, it topped out at like 60c, and that was with 1.4v going through it :p
 
Haswells seem to be incredibly leaky at high voltages. If the chip is at 1.4v then such high temperatures seem realistic even under water. I doubt it's the loop. Remember, if the TIM is poorly applied under the lid then that will limit the cooling you can achieve with water.

Sounds like you got really unlucky Martini... if you can show that the chip is not stable at stock then perhaps you can justify returning it? These chips seem so variable...

Dog chip as expected.
4.6GHZ @ 1.4v at ~90c.

That's under my water too, so pretty ludicrous.

:eek::eek::eek:

Holy ****

Using the same radiator with half the fans and a EK Supremacy I can run my 3820 at the same speed but 30c lower. Obviously the Haswell will be faster due to its IPC improvement but I don't think +30c for a little IPC boost and no HT is a good trade, I would wager I could get my chip to 5GHz and still be running cooler.

Might just DSR it.
Really wish I'd just kept my 2500k :p

I don't generally advocate sending stuff back based on lack of overclocking performance (never done it myself). But in your case I would probably consider it as well... That's a pretty damn poor showing for a CPU!
 
Yeah, I'd never usually DSR something for this reason, I once had a 2500K that struggled 4.5GHZ, I got rid of it, but it wasn't a DSR.

But in this case? Just feels like I've wasted money, it's horrifically poor.

Not just that but the fact it's unstable at stock! I wouldn't hesitate sending this one back but I probably wouldn't do it if it was just a duff clocker.
 
But can you dsr a used item?

When you use the cpu, it will leave dents on the sides where the latch holds the cpu down which will show it has been used. Won't the retailers have issue with this? As they cannot sell as new no longer?

It'd get sold as a B-Grade.

Or, if as in this case it is actually faulty, it might go back to Intel.



Regarding DSR, most retailers say that they will not accept returns once the packaging has been opened. However (as I understand it), you are able to use the product to test it, so long as it can be returned in an "as new" state (?). If you write to them stating that you are returning the product under the UK distance selling regulations, there shouldn't be a problem.

... Of course this is why buying multiple CPUs and returning all but the best clocker is such a scummy thing to - the retailer (who is operating on very tight margins for computer hardware anyway) will make a loss on the product, selling it as "B-grade" or "pre-used". This being said, the variability of Haswell does make such a thing tempting! Now if only I didn't have these pasky morals... :p

Send it back.

That performance goes "above and beyond" just being a below average chip. As you said, if you keep the chip you have effectively wasted your money coming from a 5Ghz 2700k. You'll probably be running it at 4.2Ghz 24/7.

If I were you I would send it back, quoting DSR, and requesting a refund. However I would also give them a note saying that it does not appear to be 100% stable under stock conditions. In that way they can choose to test it and send it back to Intel if they want. If it's not clear whether it's stable under water, chances are it will fall over under stock air.

I think I would be happy at 4.4ghz, or even 4.2.. coming from an 930 i7 @ 3.8ghz there's plenty of improvements for me (not least a real sata3 controller)

I'm more concerned about the temps - and ultimately the noise produced by cooling it... what sort of overclocks and temps are people experiencing with air coolers?
I was sorely tempted to go for air.. but I'm not so keen now and may get a hydro 90/110i.
 
4.4Ghz stable at reasonable temps on air would be fine for me as well. But 4.4Ghz at 90C on water? That's another story.
