i7 920+P6T DLX @ 4.2Ghz On-Air

Impressive memory access on that PCM05, looks like Core i7 might actually show an improvement in my favorite benchmark

[SAE]

Ok, so the chips aren't overclock locked?

The non-XE are multiplier locked, not overclock locked... you cannot set higher mem multiplier than 8, for example. Indeed, this hinders ocing somehow.

I was thinking all mem related multipliers should be fully unlocked, at least I remember Intel claiming this before launch?!

[Chri$ch]

memory multiplier must be unlocked (retail), otherwise this would be impossible

@ 4.0Ghz - 4.2Ghz Vcore 1.45V - 1.52V CPU Idle ~45c & run Pi 32mb 8 thread full load @ 80c - 98c.
Sometime I see temp @ 100c check for coretemp 0.99.3

Much appreciated mate. very nice results so far.

[moose517]

wow thats some real impressive results, i was initially considering the extreme chip but with all these results i'm seeing of the cheap ones made me reconsider, its not like i'm a huge serious overclocker but i think the 920 will serve my purposes just fine. I watercool and have considered a TEC for CPU so i think that will be a wicked setup

[zlojack]

Wow...very impressive stuff.

Maybe I won't skip Nehalem, after all.

All memory multipliers are available on i7-920 and i7-940, but only with newer bios revisions on most motherboards. ASUS P6T and Rampage II Extreme have them locked on earliest bios revisions.

I wonder if 3GB is enough for vista x64.

[SAE]

I got the info concering locked mem multipliers from saaya. I was also hoping for them being unlocked... would be sweet.

[saaya]

they are definately locked on some ES cpus, if they are unlocked on retail chips thats great news!

[emoners]

is that the new TRUE for the i7 socket?

[Razzz]

Really nice cpu you got there. Keep the work up.

Your ram runs fine @ 800mhz @1.6V? the specs says 1.9V just like your original test setup. Why did you drop it?

That not original spec on it, if original it'll run 1600C7-7-7-18, 1.9V but this him drop timing to 8-8-8-24 also it don't need much voltage

[XS Janus]

Hmmm.... and I thought getting to 3.6GHz will be the usual 920's speed!
Glad I was wrong!

[M3 CSL]

Very nice.

[coo-coo-clocker]

I'm gonna pick up one of these 920s!!
Now, which mobo... that's gonna be the thing?!?

ma bad, didn't notice that :p I'm surprised though the system ran fine on 1.9V without damaging anything. Is it safe and stable for long use?

[zlojack]

So what's the highest clock for 24/7 stability on this so far?

ah... sorry for wrong understood

So what's the highest clock for 24/7 stability on this so far?

I think about 3.8g will good for 24/7 stability

[panuza]

WoW cool....

[WaterFlex]

Nice chip.

P6T Deluxe 0804 Bios

1. Improve Memory compatibility
2. Revised QPI/DRAM Core Voltage setting in CPU Level Up
3. Support new CPUs.

Now THAT I knew was coming. I knew it, I knew it, I knew it. I've benn busting a gut trying to keep quiet about that becasue i didn't have any source, but I knew BIOS tweaks would have to come. They always do.

This is outstanding! These people are really working to give us good OC'ing features, and it's obvious they've worked very hard on it.

Guys if you work with this stuff PM me. I want to thank you personally. I've been waiting a long long time for this new technology, and this is gonna be so much fun. You've put the fun back into system building and OC'ing again for me. I've been out of the loop for a long time, and I'm so anxious to get my hands on this stuff I can't stand it.

I want the 17th to be yesterday so my stuff would already be on the way!

[sundancerx]

nice, 5ghz to play superpi
