G.Skill F3-1866C10D-16GAB (Ares 2x8GB DDR3 1866)
ASRock Z87 Extreme4 with UEFI 2.30
Intel i7 4770K at stock speed
Cooler Master 212 EVO (CPU temps around 30C idle)
XFX XXX Edition P1-650X-CAG9 650W Power Supply
EVGA nVidia GTX 560Ti
Memory in slots 2 & 4 per manual recommendations (link - page 20)
I'm having issues with system stability in both Windows 8 and Linux Mint 15. Several hard lockups with display active, several hard lockups while system has sat idle and display off (but system not in sleep mode), and one Windows 8 BSOD-like screen.
I have tried profiles XMP1, XMP2, and auto (1333) while leaving the CPU speed on auto. The system eventually locks up regardless of the profile (or auto) used.
EDIT
I was finally able to flash the beta UEFI 2.21B (had to disconnect all SATA drives before ASRock's instant flash worked). Although version number is lower, it was built after 2.30 - verified by file date and website. Considering the system stability issues at even 1333, the RAM may not be at fault here. I will continue testing with this newer UEFI as well as ensuring AC power to the system is stable.
