51 x multi! That's the highest multi that these Sandy Bridge board go up to? 99?

Max multiplier is 57 I believe. Who'se going to be the 1st to risk 6GHz? (Joking, dont!)

Well done mate, what is the max that you can pass 3d vantage?

Will be running some more 3d benchmarks later today.
Why Vantage?
I installed 3dmark2006 as I like it and know where i am with it.
I also installed 3DMark2011 - is that comparable to Vantage, or should I do vantage as well?

q6600 · 13 Jan 2011 at 13:36

3d vantage is very stressfull for cpu. you can do pifast or super pi with 5.1 but i think you can pass 3dvantage with 4.6

Looking good Simon.

Are you running with HT enabled for your Prime/IBT tests?

scubes · 13 Jan 2011 at 13:40

i hope it lasts for you at that speed is it 24/7? nice overclock...

Yep - Nothing is disabled

Do the sandy bridge motherboards do 16x 16x?

Nope, their 8x, 8x at the moment. You see minimal difference between the two setups anyway.

DBT85 · 13 Jan 2011 at 15:55

since its only a super pi I can join

However i'll b going back to 1.35v and 4.5ghz for the time being. 1.42v wouldn't get me to 5.0 and even thats too high for my liking. This was literally a 1 minute bump up test and back down.

5.0ghz @ 1.45v

subbytna · 13 Jan 2011 at 15:56

isn't 1.45 a bit high on the voltage side? What can these chips do in terms of safe volts?

1.35 ish is around what people think you should be sticking to for long term.

Nope. LGA2011 for that I believe.

Though I'd bet you'd hardly see the difference between 16x 16x and 8x 8x anyways

Sandy Bridge chipsets are the first intel chipsets with PCIe 2.0 apparently. So 8x8 should be perfectly fine. Though you can get some P67 boards with 16x16 as they have the Nvidia nf200 chip onboard to add more lanes.

The other major (and welcome) change is the move to PCIe 2.0 lanes running at 5GT/s. Currently, Intel chipsets support PCIe 2.0 but they only run at 2.5GT/s, which limits them to a maximum of 250MB/s per direction per lane.

WoW very nice 5.1GHz, my i7920 4.2GHz superPi about 10.659s yours at 5.0GHz just under 3 seconds faster 7.862s but watch out for the volts your putting trough.

SimonMaltby · 13 Jan 2011 at 17:22

Think I might be getting a little carried away now....

How gutting to be so close to a sub 7s time :eek:

SimonMaltby · 13 Jan 2011 at 17:32

And here is a bit of 5GHz fairly stable.

Muel · 13 Jan 2011 at 17:54

I thought the max these chips would take was 1.38v? You guys are playing with fire there! That'd be like me pumping 1.6v through my 965BE.

shadow_boxer · 13 Jan 2011 at 17:57

Dah, I want in this club...

This is what I thought aswell. Some of these voltages are going above 1.40v lol.

EniGmA1981 · 13 Jan 2011 at 18:02

5.3??? Wowser lol

Quick question, is high voltage dangerous refardless of temperature increase? that is, will just the voltage frazzle the chip regardless of cooling? Even if it was theoretically running loaded at 20*c?
