Core i7 975 XE Breaks 5 GHz Barrier, With Air Cooling

Intel's newest high-end processor, the Core i7 975 Extreme Edition is gearing up for launch later this year, on course of which, it already passed a milestone. Xtreme Systems Forums member PcCI2iminal scored one with overclocking a Core i7 975 XE D0 stepping chip past the 5 GHz mark, 5015 MHz to be precise using only air cooling for the processor, with an ambient temperature of 20 °C as claimed by the overclocker. Its cooling was care of a Thermalright Ultra Extreme 120. Its partners in crime were Biostar TPower X58 motherboard, and Corsair Dominator DDR3-1866 memory. At that speed, the setup made it through a CPU-Z validation. PcCI2iminal was further able to put the chip through SuperPi 1M at a speed of 4750 MHz, where its crunch time was measured 8.672 seconds. For more pictures and screenshots, head over to the thread at Xtreme Systems.

It's an engineering sample, so most likely it is very good silicon.

Don't you guys remember the first c2d overclocking results? They were phenomenal just like this (not 5ghz phenomenal, just phenomenal.)

Although this makes my panties wet, I still think the reality is most people won't see that kind of overclock. Still though, dayumn

Ehhh I've just got my 920 D0 and it's hitting 4.2GHz @ 1.28V so I wouldn't be surprised.

Why do these people take such rediculous pictures I mean for god sake stand back and get a decent picture capturing the monitor and setup.

It's a trade off. The C0 would operate sometimes with low qpi (which usually yielded higher OC), or high qpi (which wouldn't OC so high but had low temps). The D0 on the other hand seems to use excessively low VCore to overclock but requires higher QPI making the temperatures not that much lower than the C0. I can run a 4.0GHz @ 1.218V. I've seen System Viper get a great OC with his. So far D0s seem like a win. It's worth while to wait for one.

FX81 will be out shortly which is rumored to default to 4ghz on 6 cores so who knows but this is going to be a very interesting battle

AMD does not have a desktop 6-core CPU in its roadmaps for at least the next two years.

I've always thought of you as an AMD fanboy:eek: and this just confirms it:shadedshu :p

So when exactly is "shortly"?

so these "special" chips, they just hand picked ones? So, if correct, this meant there could be other chips out there that are just as good, no?

road maps don't list any FX series of chips either. Yet the boards list phenom FX on them funny no?

ES chips are already out as of 2 weeks ago. and i have been trying to tone down my AMD undertones hell i even played with a P4 on my last DICE bench :p

i did salute the owner on XS when it happened its a great feat. the new intel designs allowing the run hotter and clock higher :D

While that's awesome and all it would be better if that chip didn't cost around $1000. That's a crap load of money for an unlocked multiplier.

Phenom FX is an idea that neither exists, nor doesn't. It was thrown out of the roadmaps when AMD realised that they could never sell Phenom for anything over $300, and that DSDC in the form we saw in Athlon64 FX 7x was a terrible, inefficient design. There is, however, no Phenom II FX that we hear of, nor do motherboard vendors "accidentally" list/print the name in their packages, BIOS, or manuals.

i will do my best to get you some benchmarks

Yeah, my PHII hits 4 G @1.55 V.

My friends PH II 940 hits 4.3 same setup, and at 1.5 V, and ive seen one hit 4.6 on pretty much the same, suicide @ 4.8 on air @ PHII, so, when every one is hitting 4.2 on theese, THEN im impressed, dont say this is a awesome feat, just that i want more proof before im blown away by the 975 XE

Of what, a random Deneb ES with its name string / vendor ID messed with?

only if you can add 2 extra cores with a string change. why are you arguing so much with this? i have been talking to several different sources and they all have pushed this idea on me and a certain user on this forum were i got some hook ups gave me a SS or two already.

And Intel is due out with 8 core cpus. It's all irrelevant to the topic tho.

Ok, bring them up. I'm sure they're Istanbul ES benchmarks that have no traces of "Phenom" in the name anywhere. You cannot use an ES to prove the Phenom FX point since the CPU vendor string can be manipulated.

Even then, the objective behind Istanbul is parallelism, not that a numerically high count of cores makes it better in the client platform. Again, there is no 6-core client CPU from AMD, in the foreseeable future.
