Hi
Im looking to upgrade my pc memory by adding a stick of 1024 to the exsisting 512mb thats in there already.

Ive looked at the motherboard spec that came with the machine and for memory it says 3 DDR Dimm slots DDR1, DDR2, DDR3 pc1600 (ddr200) /pc2100(ddr266) max 3gb
Pc2700 (ddr333) for 2 ddr dim slots max 2gb, pc3200 (ddr400) for 1 ddr dim slot, max 1gb.

Not sure what speed the 512mb ddr is running at.

Thanks as always for your help.

Usually there is a sticker on the module that tells you. Have you looked at the RAM module?

You need to match the speed of the existing memory. If you buy faster, more expensive RAM and stick it in there, it isn't going to do you any good because the computer will clock it down to the slowest stick. If you by slower memory, you will only slow your system down.

Hi
Just checked in bios to see what it is and at what speed and it is 512mb/166mhz (DDR333) IN SLOT 3

Can you post the make/model of your motherboard?

This is the motherboard thats in the pc also the cpu is a athlon xp 2800+

3 x DDR DIMMs, DDR400/333/266
DDR 266 Max. 3GB
DDR 333 Max. 2GB
DDR 400 Max. 1GB

This means your motherboard can handle either DDR400/333/266. But the higher speed you choose, the small amount of RAM it can actually handle.

Look at the RAM already in your computer and post here what it says on the sticker.

When i looked it didnt say what it was thats why i went into bios and posted above what it said in there, also would i get away with high density or would i have to opt for low density to be safe
