Ivy Bridge 7 GHz Rips Through Pi

Intel Core i7-3770K is turning out to be a monstrous overclocker, when assisted with extreme cooling such as liquid-nitrogen. One such test-bed, was overclocked close to the 7 GHz mark, and put through Super Pi (1M and 32M), and PiFast. At 6961.6 MHz, the chip ripped through Super Pi 1M, in 5.187 seconds. The same chip, clocked at 6650.1 MHz, crunched Super Pi 32M, in 5 minutes, 2.843 seconds.

In PiFast, with a clock speed of 6805.1 MHz, the chip hammered out a total computation time of 10.56 s. NordicHardware compiled a comparison table using HWBot and its own data, to reflect how much faster a ~7 GHz Core i7-3770K is, at Pi. The rest of the known test-bed consisted of ASUS ROG Maximus V Gene Z77 motherboard, and 4 GB (2x 2 GB) of dual-channel DDR3 memory, clocked at around 2652 MHz, with timings of 7-11-7-28-1T.

cpu-z only shows what you have enabled or disabled, so you can disable HT on a 3770K , but CPUz fully supports Ivy bridge, even has the correct stepping revision.

this is very nice indeed. I wonder if we will ever see another 7ghz CPU, as this is E0, no one is using E1 for extreme, and it seems E1 has better air OC, and those nice 5ghz with lower volts are done on E1, E has those terrible air/water, so it has higher leakage and thus performs like this. I wouldn't like it if only E0 ES did well, because then you can't compete with retails.

For those who are interested in what's really important witch is a stable 247 overclock
you might be disappointed.
That is disappointing, but we are talking about engineering samples. The real deal will be interesting.

I bumped into a lot of ESs that overclock great, above the average ability of a shelf product

Depends on how each steeping does i guess.

Bad overclocking, no reduction in consumption, a stupid smokescreen of benchmarks and a tiny performance gain. Thats even less then expected.

Not really unlike what they did with BD to get the world record these guys did it for stability! No at all a smokescreen!

That BD overclock was stable, that is why they recorded it on record. We are talking about none realistic scenarios with LN.

firstly well done, nice oc

Whats going on with that graph and its info though, no stock 3770K on it and why does a i7980x still hold the world record? with 6.042 Ghz and a slower time too, and i take it thats a world record for an all cores on OC , as AMD got 8.something out of an Fx with 1 core running?

and another thing why has performance not improved very much , nigh on 11% improvement over a 980X with 30 extra clocks and a generation swap and shrink ,between the two?? sounding a bit BD this increase

Can you attach the power consumption graphic also please? ;)
Can't be any worse than AMD silicon, that's just unpossible. . .

No it was not! They also used LN not air. No test were done at the 8+GHz at all! Show me some that were done! At least they ran a test on this one at the speed they got. Also they ran ONE CORE on the BD not all of them!

I'd rather have a chip that starts at 8 and can be overclocked to 11 than one that starts at 5 and can be overclocked to 9.

Again, you are always the first one to mention Bulldozer in an Intel thread.

Anyone know of a OpenCL Pi program?

And again, you are the first to hack his face off for it. Chill the f*** out man. It's just trickson, didn't you learn too ignore people that irritate you? He irritates me sometimes, i just ignore him.

I agree, if you (dent1 & trickson) have nothing better to do but troll, maybe your should take a break and calm down. There will always be that Intel/AMD/nVidia fanboy and the best you can do is ignore it if it annoys you, however considering how this is a IVB thread, I'm wondering why people are talking about BD to begin with.

I think sticking with the topic at hand might help. :D

This to me is a true overclock worthy of a world record! I mean all 4 cores and stable too! This is supper cool to see. And I love the thread title too!

Whilst its a good overclock, I see no evidence its stable. If your definition of stable is booting up Windows and running Pi only to have the system lock up and blue screen 10mins later. This clock its more likely a suicide run, unless the article says otherwise.

Regardless Ivy Bridge is looking impressive. When I find more leisure time I'm going to be upgrading to Ivy.

I would agree, As this is not a conventional cooling solution nor a 24/7 over clock it is still impressive. I would argue there was some stability as the chip was over clocked on all 4 cores and ran pi at both 1M and 32M granted on a suicide run but never the less it still was stable enough to RUN the tests! That in and of it's self deserves a :toast: If nothing else.

Obsolete CPU

by: trickson
Man that is so incredible! Way to go Intel! Say what you will this was a great run for the chip!
your hardware is obsolete, Tom ! time to get new stuff !!! : )
