Asrock Z77 Extreme4 & Extreme6. Report issues, overclocks, and related stuff here!

I just build my i5-3570k last week on an Extreme6 motherboard, I'm very happy with it! I am using BIOS 1.94 and modded it with a newer Asmedia, Intel SATA ROM, and even though I don't use it, Broadcom ROM.

How about this though... it did surprise me a little regarding memory. I am running Gskill 2x8gb DDR3-2400 RAM (F3-2400C10D-16GTX) at 10-12-12-31-1N, I was very surprised that it has been perfectly stable at 1N, even after stress testing, memtest etc. I am also running a refresh period of 14500, instead of 9380. The rest of the settings are on auto. I think this would have to do with the newer BIOS, because on the original bios I don't think the system liked it too much! When I first turned on the computer (very first time), I had to press the clr CMOS switch at the back for it to boot (which put the memory back to DDR3-1333). I already premodded the bios so that was the first thing I did after I made sure the system would boot again after turning off. This had nothing to do with the RAM settings, because as I said, it was stock at that stage!

As I am running 2xCoolermaster Excalibur fans for the CPU:
Speed (R.P.M.) 600 - 2000 RPM ± 10%
Air Flow (CFM) 26.4 - 85.6 CFM ± 10%
Air pressure (mmH2O) 0.75 - 3.53 mmH2O

I modded the AXTU config files (what is the difference between the z77e6.xml file and z77e6TB4.xml file? mine uses z77e6TB4.xml) to adjust the fan profiles, with these cpu fans it makes no difference to the cooling between around level 5 and level 9 apart from noise, so I scaled the new settings so level 9 to basically what level 5-6 was, although it doesn't seem to make any difference... lol. Any way to limit the max CPU fan speed?

EDIT: Using Speedfan now (you have to set it up properly for CPU fan control), seems to have much better CPU fan control options.
