Hello all,
I got a used Asus Rampage Extreme-based system (socket 775, Intel X48 chipset) that came along with two G.Skill 4Gb F3-10666CL9-4GBRL sticks.
I have installed Windows 7 64-bit on the system but have not overclocked anything. BIOS settings are currently all at auto. Now I've been experiencing system freezes for certain applications (Firefox mainly) so coupled with the fact the rampage's user guide does not include the G.Skill in the QVL, nor does it seem to support 4Gb sticks (although they both seem to work), I am checking the possibility of RAM problems. So, I got some questions:
1) Does this motherboard support these 4Gb sticks, or not?
2) If yes, any idea if they should be installed in specific RAM Banks? Manual states in page 2-14 that DIMM_A2 and DIMM_B2 should be used if 2 sticks are to be installed, for dual-channel operation. The system I bought had these ram sticks installed in DIMM_A1 and DIMM_B1. Have left them that way, since I'm a newbie here...
3) Anything I could tune not for overclocking but for stability for these sticks / mobo combination?
Of course (2) and (3) above should be answered only if the answer to (1) is positive.
4) Anything I could try to check RAM? Would memcheck at Windows 7 boot provide any info with regard to possible ram issues?
Some more info: I have not encountered any blue screens or other issues. My freezes affect only the current application (firefox, zoombrowser ex etc) and not the rest of the desktop. Finally, some output from cpu-z if it helps:
Any info will be appreciated. My turf is mainly software, so I am at a loss here...
