Wondering if I could get some help/advice. My current computer hardware is AMD Sempron 64 AM2 3000+, Kingston DDR2 667 1GB RAM and my motherboard is a MSI K9VGM-V AM2 A10 DDR2 PCIE.

The specs on my motherboard states memory standard of DDR2 800, max of 2GB dual channel.

Now I want to upgrade my RAM to the max my mother board can handle which is 2GB. Currently I have a Kingston DDR2 667 1GB RAM. Would you suggest just purchasing another DDR2 667 1GB RAM and add that to my PC (so I would have DDR2 667 2 GB (2 X 1GB) and if so do I have to purchase the same make or could I go with another make Crucial etc (of course I will get DDR2 667 1GB RAM).


Do you recommend just purchasing a new one which would be DDR2 800 2GB RAM (2 X 1GB).

Do you think the speed is worth a full upgrade or just the addition of the DDR2 667 1GB RAM which would give me DDR2 667 2 GB (2 X 1GB) would be good enough.

My computer is a HTPC so basically the use of this computer is to play movies which are compressed Blue Rays typically 720 not much game play done and just regular downloading and converting file formats and word programs

Thanks in advance any advice would be appreciated

Just add one 1GB module so you have 2GB and can use dual-channel (128-bit) interface.

Also, you don't need DDR2/666, you may just buy a DDR2/800 module also as it will downscale to 666MHz. Its the BIOS that decides what speed the memory decides on, the memory itself can only advise about its recommended settings inside what is known the SPD. The BIOS can and will override these settings depending on configuration.

Do take note that the latencies of your new memory module do not exceed those of your current module. It'll work but the slowest part in the chain dictates the overall speed. If you would add DDR2/533, both would run at 533MHz. Same goes for the latencies (CL4/CL5, etc).

for me id go with 2 X 1 go ddr2/800 because its cheap but not much different in speed improvement.

Basically depends if you plan also on changing comp soon and what budget you gave

whats the difference between 1 go of ddr2/800 and ddr2/667??

+ 1 sub mesa for dual channel: computer will work faster
