Hi,
I'm experiencing serious troubles with an Asrock P55 pro and 8GB (4x2GB) RAM (2x F3-12800CL7D-4GBRM).
If I install only 2x2GB (in the white slots), using default bios settings, the system starts and works fine ( no memory problems detected with MEMTEST+ 4.0 ). According to CPU-z, memory settings ( auto-configured, NO OC ) are 533Mhz 7-7-7-20. Probably something better can be achived (even if I know this RAM model IS NOT in the motherboard QVL).
Even (a lot) worse if I try to install 4x2GB: the system CAN'T BOOT, even if I clear CMOS (reset BIOS to default)!
Is there any known issue using Asrock p55 pro and 8GB (4x2GB) F3-12800CL7D-4GBRM ?
Are there some "good" BIOS settings that let the system boot with 8GB (even with lower frequency) ?
Do you think this is a compatibility issue or there is a problem in the RAM modules (or in the motherboard) ?
Thanks in advance for your answer!
P.S. More system details:
Bios version 2.0
CPU Intel i5 750
Power supply LC-Power Ozeanos metatron lc8650 650W
ATI Radeon 4770
Windows 7 pro 64
