? about DDR2 ram do u need 2x512mb or can u just have a 1x1024mb?

Answer 1

As a few people mentioned the issue is dual channel mode. If you have 2 512 sticks, you can run in dual channel mode, but with only 1 1GB stick you can't. Dual channel effectively doubles the memory's bandwidth, hence it is an extremely good idea to run in dual channel mode.

Answer 2

You can mix them too. Say you bought a 1GB stick and had a 512 MB stick, just use them both and have 1.5 GB of ram!

Note: they can vary in speed and will only work at the lowest sticks speed. Not a big deal as having 1.5 GB running at a slightly lower speed is better than having 1 GB running at a slightly higher speed.

Note 2- DDR and DDR2 are NOT interchangeable as the notch in the edge contact is offset a couple Milimeters from each other and the wrong one will not go in the slot.

Answer 3

You can have either setup, but two matched sticks running in dual channel mode will have better performance than one stick with the same size as the two smaller ones combined.

Answer 4

You can just have 1x1024.

Unless you want to run it in Dual-Channel mode which will help performance. In that case, you would need 2 sticks to run dual channel.

What I would do is buy the 1024 stick now, and buy another later on and THEN run them in dual channel.

Answer 5

DDR2 ram is just a type of ram. The second edition of regular DDR.

The amount of ram you have is upto you.

If you can afford getting simply 1024 mb (1GB) ram straight - go with that.

Answer 6

Hi. I think either will work, but I think the 1Gig stick can be faster.

depends on your machine. get the memory from www.buymemory.com
