Seing as the memory controller is in the CPU now, will the CPU temperature increase if you feed the memory chips higher voltage? Like say the difference between having 1.50V and 1.65V memory.

These are my specs:
Gigabyte GA-P55A-UD4 Socket 1156 P55 (Rev 1.0)
Intel Core i7-860 2.8GHz 8MB (x12 memory multiplier cap)
Corsair XMS 4GB (2x2GB) DDR3 1600MHz CL9, 1.65v
Nvidia Geforce GTX 580 1536MB (reference)

...but I'm running the memory at standard SPD 1333Mhz CL9 1.5v. Because of all the weird things that happen when the XMP profile is used. I detailed that in nother post called 'XMP is messing with me! It even rhymes!'

I'm not much into the overclocking stuff anymore, but I do have a fair grip on how it's accomplished. I pretty much just got into the whole bag with BCLK and memory multiplier caps in the CPUs, etc.

Thanks for confirming the temp thing though.

Yeah that's what I figured too. I've been considering buying some Kingston HyperX 1333MHz CL7 chips, though they do require 1.65v I believe.

My CPU temp 20-25C idle and 40-45 at max stress across the four cores. That's with a Zalman CNPS Flex heatsink and low-RPM Akasa Apache (4pin) fan.

When I enable my XMP profile, which sets my memory to run at 1600MHz and use 1.65v, the CPU idle temp goes up to about 30-35C. But, the CPU is also running with a x22 multiplier then (normal is x21) and it never throttles down to save power. So, I can't really tell how much the extra 0.15v impact the temp seing as most of the extra heat must be caused by the extra high 2.93GHz clock. My CPU normally (with standard SPD memory settings) only runs at 2.93GHz when all four cores are being stressed and Turbo Boost kicks in.

I'd be lying if I said I haven't thought of it. But nah, I worry too much about the warranty. I just get these awesome coolers to kill the noise. Ever since the Intel Celeron days, when I overclocked my 566MHz CPU to 1241Mhz, using the vacuumcleaner as a CPU-fan, I've hated noise! hehe

Gotta say I'm extremely happy with the noiselevel atm. The GTX 580 is extremely quiet, and it only ever reaches 75C at max stress during 3DMark 11. I hear these cards usually hit 81-83C. The cool hard steel case from Chieftec might be helping on the overall temp though. It weighs a ton and a half, but it's always cold to the touch.

That's a nice clock for the i5-760. I've heard good things about that Hyper 212 Plus cooler actually. What's the core temp with that clock?

I don't have an SSD yet, but I got one coming in the mail with my SandyBridge upgrades. Can't wait to see how fast normal windows operation gets.

I got my computer hooked up to a 24" LCD monitor and a 40" LED TV. Gotta say I enjoy playing Street Fighter IV on the big screen with a Xbox 360 Controller in hand. It's like having an Xbox 360 on steroids. :) 

My 3DMark 11 score (Performance): P5834

It jumped up a bit higher than that with the XMP profile enabled, but I didn't keep that score.

Not bad.
