Hi, My desktop has 3 slots for DDR 2 type of RAM, but is ok if I install 3 RAM sticks of different size, speed and make? Is it possible to have a 1 GB RAM in the 1st slot, 2 GB in the 2nd and 3 GB in the 3rd? Thanks

installing different types of RAM is a bad idea. capacities should not hurt much. it is usually best to have the same brand and model RAM though.

you dont get 3GB RAM. its always in powers of 2. Also, DDR2 is dual channel so best to install in 2 slots. Get 2 * 4GB RAM and that would give you the best performance.Also remember that dual channel slots are usually alternate ones, so you should install in slot 1 and 3. check your motherboard manual though.

Id say 2*4GB. Gives you more head room for later upgrades and puts lesser strain on the chipset on the motherboard which will have to get data from lesser units.This is for DDR2. DDR3 is tri channel so 2*2*2GB will be good.

oh ok. so if i have ddr3 i would get one more chip. if not, i would get 2 more :D

i do think i have ddr3. this desktop was updated last year with a pretty decent motherboard.

ok i have:


Physical Memory : 4096MB (2 x 2048 DDR3-SDRAM)

i have survived well with 4GB RAM, i guess i can get a minor upgrade now and see if I would be able to saturate 6GB RAM!

----------

errm. 4*2GB meant 4 units of 2GB RAM or 2 units of 4GB RAM? :confused:

How much is the average ram usage these days ? @admin, do you saturate your 4GB ram anytime ? I remember long time back during the 128MB ram days, the harddisk used to kick in after the ram getting filled.
