I have an ASUS P5QC MB and one of my old Cosair DDR2 sticks recently failed on me, so I decided to get new memory sticks. Since my motherboard is capable of accepting both DDR2 (4 slots, 16 GB max) and DDR3 memory (2 slots, 8 GB max), I decided to buy some Kingston DDR3-1333 8GB memory.
After replacing the sticks, I tried turning on my computer, only to find a blank screen, but everything else still running (fans running, HDD ok, etc). I ran a few tests both with the hardware and BIOS and listed the results below:
- Booted computer with one stick of DDR2: Normal boot
- Booted computer with one stick DDR3: computer running, but no monitor
- Cleared CMOS and booted with DDR3 RAM: same issue
- Cleared CMOS and booted with DDR2 stick: Normal boot
- Removed all RAM and turned on computer: computer running, but no monitor
It was with the last test that I realized that I did not have a system warning speaker plugged in...but from what I have tested, my impression is that my MB is not recognizing the DDR3 RAM, despite having slots for it. Givent his, my question is whether I should just return the DDR3 RAM and just buy some DDR2 or if there is a way to get my computer running with the Kingston memory.
Thank you in advance.
PS: I am unsure if this matter too much, but my CPU is intel core 2 quad.
