Hi everyone! I wanted to install new ram on my MSI955X Platinum Mobo. The existing ram is 3GB. The mobo has 4 slots (dimm1, dimm2 and dimm4) and can be ugraded up to 8gb. I bought a 2GB DDR2 667 mhz but when I installed the ram, it doesnt detect the new memory. I thought it has modules configuration so I inserted another 1GB to fully utilized the slot but the problem is still there (dunno what i am doin' wrong). My total ram are as follows 2GB, 2GB, 1Gb and another 1GB. Please help.
