My first impression is that IB overclock and temps seem okay for daily type useage. Booted into windows at 45x and then decided to test 46x which was a common 24/7 "crunching" overclock for me with SB cpus. Vcore set to 1.35v in BIOS with vdroop enabled (my combo droops to ~1.25v load) also running on die graphics with a voltage bump at 1.3v... all other voltages at default and dram at 1.5v. Cooling is under water via XSPC RX240 on an open air bench. Ambient temp is ~21.5C.
Okay some initial results on the 3770k on my MIVE BIOS 3208 (with a Venomous-X cooler). Ambient temps in my office at 24C +/- 1-2C
Maximum temperatures after 2 hours of blend at stock was 58C
I turned off the PC after that and decided to go for 4.5ghz (45x100) tried at 1.2 and it wouldn't get into Windows, went to 1.25 and it booted right up. Ran through Prime95 for an hour and maxed out on the hottest core @ 83C.
I have now rebooted and turned off HT (basically turning it into a glorified 3570k) and am watching the temps. It looks to be hitting a max around 73-74C.
So overall not bad, I haven't had a chance to do any real benching with it yet. I think I will be waiting until I can take it cold and maybe even until I have a Z77 board.
A few issues that I have run into:
The MIVE does not appear to like working with the CPU and my RAM (2x2GB Gskill DDR3-2200 CAS7 - in sig). I can't get the PC to boot consistently at DDR3-2000 [gives what I assume is an IMC error]. It will boot OK at DDR-1866, but that isn't what I spent $150 on 6 months ago, and it worked just fine with my 2600k. I have another set of 2x4GB DDR3-1600 sticks, but wanted to try my benching ones first.
Here's hoping for another BIOS updating that may fix the RAM issue otherwise I am waiting for the Maximus V Formula to come out.
One other issue was when my OS would boot both of my monitors would go into power save mode. I had to reboot multiple times to have them have a chance at booting properly. I then went into safe mode and uninstalled them and tried reinstalling in Windows. Upon the next reboot the same issue happened. So far the only solution I have had is to let M$/Windows install them itself instead of the ones I downloaded directly from nVidia (apparently Win7x64 installs the 290.** drivers) - haven't had the sleep mode issue since doing this.
Those are some good temps on water.
