I was thinking the same thing. I'm going to re-seat the cooler onto the CPU and hopefully get a more even heat spread. But I also heard that having a ~5c difference between the cores is normal on this chip? I'll report back once I get a chance to re-seat.

Nope. I've played with three 920's so far and all of them had uneven core temps like we're seeing here. I wouldn't worry.

So excited to start to 4.0+ghz benching
Awesome! Yeah, benching can be a lot of fun. Keep us posted with your results.

72 hours in and the thing is running like a champ! Though now im going to turn up the heat and instead of doing progressive encoding (which has gaps of idle activity for a couple hours every few hundred files) im going to ramp this thing up with a video queue of over 1500 files, lets have this thing encoding litterally 24/7 for the next couple days and see how it goes (man the encoding power of these processors are awesome, ive already blown through 2600 video files at 2 bitrates in just 5 days LOL). Back in 2008 I had 4 dual opteron servers encoding simultaneously for 3 months straight just to encode 1800 videos at 5 bitrates. So yeah, you could say I'm really impressed. i7 = the encoder's essential proc.

i heard oc ruins the stability/quality of the encoding. is this true?

Depends on how stable your overclock is. I am doing renderings on mine and they are great. But I've had two crashes so far so I'm going to try the suggested settings above for 4.2. When in doubt, I go higher.

Not in my case, the files look perfect, they sound perfect, and most importantly for my application -- they stream perfectly from our web server. There is no issues at all with the encodes, but I do believe the poster above me is correct, it is dependant on how stable the overclock is (thats why I don't wish to go higher than 4.0 with the i7 920 [D0 Stepping], it is simply not necessary for the amount of encoding performance I can get out of that clock). The encodes I'm doing are for work, so it is absolutely vital that they are the equivalent of the type of encodes to be had from a non overclocked system (if overclocking would corrupt my encodes, I would simply bite the bullet and buy a faster processor with speeds close to 4.0ghz, or encode from a non overclocked processor - maybe buy a 3rd i7 encoding workstation to offset the loss in time LOL).

Yeah, it's funny to see what people's idea of "stable" is when they stress test their CPU's. I just took a gander over at the i7 920 Batch Guide Thread and saw people claiming 4.2ghz @ 1.20v, yet the stress test they ran on it was, in my opinion, pretty pathetic. IBT - Standard - 10 passes? Come on.. Oh well, to each their own I suppose.

Actually, because of you (fallen again), I started using a higher stress testing level because of your feedback regarding the longevity of the stress you're putting onto the CPU. I'm glad that you were able to test out my OC settings, so that I can make sure people like you who do encoding or even folding can actually max out their processors 24/7 and get a truly stable OC. The voltages may show a tad higher than some other people on here, but, you know you're getting a good stable OC at the lowest possible voltages, or at least, that's the goal.

/rant

Hehe, anyways I'm happy to continue providing these OC settings. I'm working on some lower OC's now (3.8GHz) for those of you who don't want to go as high as the 4.0GHz mark. I'll also follow that up with a 3.6GHz OC next.

Okay, I've done some more testing with this motherboard. For those who want to run their i7 920 D0's @ 3.80GHz at the lowest stable voltages, here are my BIOS settings.

NOTE: These settings were stable for me and should be for you as well. However, not all i7's are created equal, so YMMV. That said, these settings were tested against LinX - / Problem size: 25854 / Memory to use: 5120 / Times to run: 20. If you guys see some additional tweaks or changes to make this even better, please share.

==================================================
!!! UPDATE !!! - Users running Intel i7 930 Chips
==================================================

Follow the guides above and substitute with these settings below.

**************************************
Running 3.80GHz w/o HyperThreading (Stable)
**************************************

Code:
CPU Voltage............................[unavailable]
QPI/DRAM Core Voltage..................[unavailable]
**************************************
Running 3.80GHz w/ HyperThreading (Stable)
**************************************

Code:
CPU Voltage............................[1.18125]
QPI/DRAM Core Voltage..................[1.22500]
NOTE: If these settings aren't stable for you, they should at least get you a good baseline to go by. You may need to slightly increase your "CPU Voltage" and/or "QPI/DRAM Core Voltage" one bump at a time from this point to get something stable for your specific chip.

Has anyone used the onboard RAID controller (Intel ICH10R chipset) yet? Just curious to hear from anyone's experience using it so far. I'm planning to run a RAID5 array with it soon, using 3x 1TB drives.
