Hello, I have this motherboard in the following configuration:
Athlon 64 3500+
2GB (4x512mb sticks) Kingston HyperX DDR PC3200 RAM
250GB Seagate 7200rpm SATA HDD
ATi Radeon X1600 Pro 256mb PCI-e x16
A while back, I wanted to remove the CPU but encountered some difficulty as the thermal compound had stuck the heatsink firmly to the CPU, and I ended up pulling the CPU out of the socket still attached to the heatsink as I removed it. I then tried heating the CPU and heatsink with a hairdryer to soften the compound so it could be separated. This worked, but when I put the CPU back in the system, it would not boot but just made a long 'beep' every 3 seconds or so, so I assumed the CPU was damaged and bought a new Socket 939 chip (Opteron 185).
When this arrived, I installed it but it would stil not boot and made the same beeping noise. As the CPU was brand new, I knew this wasn't the problem so I removed all the RAM chips apart from a single 512mb stick in the first RAM slot and reset the BIOS, and it booted into Windows perfectly.
I then added another 512mb stick in slot 2, and again it worked fine, recognising 1GB of RAM in Dual Channel mode. However, It will not recognise anything in the other two slots. When I put the other 2 512MB sticks in, it either hangs at POST or makes the same beeping noise with nothing on the screen.
I have tested all 4 of the RAM sticks on their own in the first slot, and they all work fine. Is my motherboard faulty, or does the Opteron not like the RAM?
Thanks.
