P67A-UD4-B3 (rev1.1 printed on board)
i7-2600k
OCZ Reaper 4GB DDR3-1600 (PC3-12800) CL7 (Mfr part # OCZ3RPR1600ULV4)
OCZ 120GB AGIL 3 SATA3 SSD (Mfr part # AGT3-25SAT3-120)
Thermaltake TR2 RX750W PSU (Mfr part # TRX-750M)
Zotac GTX570 1280MB (Mfr part # ZT-50201-10P)
Installed Windows 7 64bit, had the random (only at idle?) freeze issue running stock. No event logs were apparently generated as the system would just freeze. I made sure I had the latest drivers etc, and flashed to the latest bios (official release 3 I think, though 4 is out now).
Anyway I noticed with cpu-z that the ram was running 7-7-7 and at 1066mhz. I went into the bios and manually configured it to run at 1600mhz and 7-8-8 still at 1.5v like it's supposed to run. I haven't had any freezes since, and it's been several days of various benchmarks, gaming sessions, and idle periods.
Just thought I'd share, my issue appears to be fixed.

Hi and welcome to the Gigabyte Forum.
Thanks for sharing that bit of info with the forum as I expect there are others in a similar situation. Badly configured memory can indeed cause the type of symptoms that you complained of. ;)

Hello, I have been having very similar freeze problem while I play my game, which forces me to reboot everytime.
I am interesting in how you know what your RAM timing is supposed to be (you said it was supposed to run at 7-8-8, but I googled your memory stick, it says 7-7-7-24)? I have CPU-Z and will be able to find out what it is running at, but I don't know what it is supposed to be running at.
I have the same motherboard as yours, and I have i5-2500k.
Thank you very much.

Hi
Well if you go on the memory manufacturer's website you can find the particular specifications for your memory. It will also probably have it stamped on the modules themselves.

Understood, thank you.

While trawling the Corsair forums looking for clues as to why I was getting memory errors, I noticed fairly often that many motherboards don't set the memory's Command Rate timing correctly.
It was quite common to see Command Rate being set to 1T when the memory's specs were 2T. Further reading confirmed that a too aggressive Command Rate was a common cause of memory errors or system instability, and resolved by manually setting it correctly.
IIRC, Command Rate is not specified in the SPD, so the BIOS has to guess the setting.

Correct again!
