not at all, even without spreaders

Even at 1.85v with SuperPI 32M running they never get hotter than 28-30C (ambient of about 17-18C) according to my IR Thermometer...

Ordered some heatspreaders, just in case. I am currently testing on my new board.

Crashed during Prime with 1.65v @ 2400MHz 11-11-11-28

Bumped timings to 12-12-12-31 and testing again. I was also getting occasional BSOD with x101, x124, xFC

I decided to increase my CPU voltage offset to +.030, I went up two clicks on IMC .0935, and VTT up to 1.055

CPU runs a lot hotter during stress testing, but I'll never utilize that much processing power so I think I'm safe. Temps will probably hit 90 on the CPU. In a tough spot. I want to keep the CPU OC @ 4.5Ghz, so basically I may have to sacrifice RAM speed/heat by decreasing voltages on some of the CPU options. Any input would be great!

Super PI completed 32M in 7m 22.748s

Now prime crashed one worker, but I'm not sure if it's CPU or RAM. I added voltage to the CPU offset to try and figure it out.

Dropped vCore and bumped IMC and VTT, now running Prime and already doubled previous run time. I hope I can squeeze out better timings.

I'm going to try dropping to 1T from 2T next, and if that's a go, then I'm going to start dropping timings.

Got some heat spreaders in yesterday- better safe than sorry- and cranked it up to 1.65v. BIOS voltages had to go way up due to random stability issues Vtt@1.1 and IMC@1.095 (Gigabyte Z77 board).

Timings are 10-11-11-26 2T (with 4 sticks it will not do 1T) and it's been working fine. Unfortunately, voltages and crappy CPU make it too hot to stress test as my ambient is about 80 degrees F. I have tried to run Memtest+ but the memory reading by Memtest shows it is being downclocked during the test. I have never seen that before with Memtest. For now, I'm leaving the overclock, but I may later have to drop the CPU down to 4.4Ghz from 4.5Ghz to see if I can get better temperatures by dropping vCore.

If anyone could offer suggestions on tweaks for some of the other RAM settings I would appreciate it. All of the more advanced memory settings are on AUTO.
