Good too see. How about some temps there chief?

Yikes. Very nice OC.
I think 4.2GHz for every day computing on water sounds doable.

The 130 watts limit does not seem to be troublesome :D

Very nice results...

Just wondering about the Vdimm. I was reading that > 1.6 Vdimm will result in CPU Damage due to the on die memory controller. Has this been debunked? I've got some 1600C7 (2 X 2048) @ 1.9v. If i7 does not have this limitation then I will wait for it, but if the limitation is applicable, then I will just stick with Core2 for now.

Great job dude :up:

Welcome to Xtremesystems m8 :welcome:

I7 looking good even the 920 looks like it worth the trouble :)

thanks for the results !!

Welcome, nice tests, thanks for sharing :up:

HAHAH thats one EVIL 920 :D

Great CPU it seems. :up:
Very detailed testing, too. Keep up the good work, mate.

Great job mate. What is max stable frequency ?

Nice results, looks like the 920 clocks rather well.:D

nice man
does your multi drop to 20x when running 8xinstances of SuperPi or maybe 3DMARK06?

Cool man keep pushing.....nice work on turbo V mode...

you get more performance than a QX9770 (USD1400) with a USD 300 CPU this is really amazing.

So there is no over clock lock? Awesome.
Cause i was just reading a Toms hardware article that says "all standard models are equipped with an overclocking lock."

Yes. the multiple Drop to 20 when running multi-thread. ;)

very nice testing! thank you for sharing, 32M is so nice with these i7

nice scores! but why do you disables CrossFire when you put two cards to your system ?

I test in CF Mode but GPU-Z 0.2.8 check disable CF. :(

For PCMark05 I test VGA single card mode. :)

@ 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 :eek: check for coretemp 0.99.3 :eek:

Ok, so the chips aren't overclock locked?

are you sure?
I think you 05 score is to low for CF enabled

5300+kb/sec winrar:shocked::shocked:
thats a hell of bandwith :eek:

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

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

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

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

Much appreciated mate. very nice results so far.

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

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.

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

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

is that the new TRUE for the i7 socket?

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 ;)

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

Very nice.

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?

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 :)

WoW cool....

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! :yepp: 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! :yepp:

nice, 5ghz to play superpi:)

i cannot see the option for turbo mode in the bios, so turbo is 21x multi right??? or is there more to it, and where in the P6T bios is it, using 0804, currently sitting at 3.2ghz @ 1.1v

to use turbo on p6t, just stick the multiplier to auto.

I wish I could give you some hands on experience but my Core i7 920 has just left Toledo. The next best thing I can do is tell you that I will be looking in the Ai Tweaker menu for this ...

Intel Turbo Mode Tech [Enabled]

That option should enable or disable the Turbo Mode according to the manual.

From one review this is how they achieved 3.8GHz.

Ai Tweaker
Ai Overclock Tuner: Normal
CPU Ratio Setting: Auto
Intel SpeedStep Tech: Disabled
BCLK Frequency: 190
DRAM Frequency: DDR3-1523MHz
CPU Voltage: 1.35V
DRAM Bus Voltage: 1.66V

They did this with the Turbo modes off. I'd like to see what happens when it's enabled. I'll have to wait until Wednesday to find out.

With auto its still at 20 :shrug:

You have to disable CPU TM also, located in the Advanced CPU section.

nice m8, batch?
