If you don't mind that would be interesting. I've been out of the loop on cpus for a while and just starting to learn about the I7s

I have noticed that one core is running 4 or 5 degrees lower than the others, not sure why I may have to remove the HS and redo the paste again. Tehn try upping a bit more
That's what I'm running. I still haven't installed my True, but on stock with a makeshift duct and an additional 92MM fan (at the top of the duct), it sits ~ 75c fully loaded. Maybe 80 depending on the heat, but well within limits.

Yep its normal I guess if I was not expecting it, it would look strange but thatís what they all do. Also I I put my rear and top fans to medium or full speed in my Antec the temps drop by about 4 degrees. But I only speed them up when gaming as I like a quiet PC when not.

What does "upping the speed without touching the voltage" include?
I am thinking of trying this first.

What kind of temps are you guys getting on the mch (uncore stuff)?

I'm not so sure this new GTZ block is making perfect contact with the cpu, because I'm getting 60C on that, but 40C on all the cores of my new D0@4Ghz.

Just finished installing my new Noctua HS and quickly testined 3.5ghz.

Anyone got a quick guide for overclocking? It's quite different from Core2.

Magus I used http://images.tweaktown.com/imageban...2.12_(ENG).pdf

as the settings on our UD3R's are the same as the higher range Gigabyte X58 boards. I have not tried mine to 4 yet running atm at 3.8 now after running at 3.6 for a few days but going to try 4 shortly

Think I need to reseat my HS. I got my CPU to 3.8 and occt failed after 10m due to hitting 90C. I'm idling at 45C at stock which I thought was too high according to tests I saw.

Hmm have you tried it without HT? My 920 reports ridiculous temps with HT on(even with watercooling). Some of the 920s apparently suffer from bad temp sensors.

I have HT disabled. I hope my temp sensor isn't bad (I do have an ES Model).

Have you used the gigabyte utility? how did you like it?

I have heard the Gigabyte utility is flakey and bad to use. I would stick to overclocking via the bios only.
