I recently upgraded the memory in an MSI-6547 socket 478 from 256 megs of PC2100 to 2 Gigs of Kingston PC2700, CAS Latency 2.5, 2.5v. The motherboard can take a total of 3 gigs but was not designed for dual channel. The memory installed fine and the system immediately recognized it. Here is where I could use some insight. The BIOS shows the voltage at 2.6v but CPU-Z shows both sticks at 2.5v which they are designed for. Also, CPU-Z shows stick 1 at frequency 133MHz but the second stick at 166MHz. The CAS for stick 1 is 2-3-3-6-11 and the second stick at 2.5-3-3-7-11 I don't know why there are descrepencies. Anything I need to be concerned with? This isn't my system so I want to make sure it will be done right.
