IM currently using CORSAIR XMS2 1GB (2 x 512MB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory .
My Biostar 550 mobo has 4 ram slots, and I thought I would have a 2 x 1gb module of the same ram type as above to give me a total of 3 gb ram.. But, Corsair says NO NO... They say I should NOT mix the different sized modules, even though the ram is the same kind... They say I should ONLY add 1 more of what I have above, giving me a max total of 2 gb.. If I want more than 2 gb memory, Id have to buy 2 2x1 gb modules.. NO mixing. I thought as long as I stayed with the same ram type, speed, etc, Id be fine.. Im very surprised.. Does everybody agree that, if you have one of your two ram channels filled, you can only populate the second ddr2 channel with exactly whats in channel 1, not just in terms of ram type and mfg, but in terms of Quantity too??
Edit*** Since I wrote this, Ive learned that Corsair seems to Always give out this advice, but the truth seems to be that on the newer 64 bit boards with DDR2 ram channels, while it IS best to use the same type of ram in both channels, its NOT necessary to stay with the same module Size. ie, it should be fine to mix a 1gb ddr2 module in channel 1, and a 2gb ddr2 module in channel 2, so long as the ram type, speed, timings, and mfg are the same for each channel.
