Upgrading DDR ram on an 939 platform.


Recommended Posts

Hello all!

I have pair of 512MB mixed RAM running in dual-channel configuration on my computer now, and feel that it might be worht an upgrade.

The only problem is that I can't decide if I should settle for 2 GB RAM total in DC or if I should go for 3 GB RAM total, if I buy a 1024 MB module now and another one later during summer or so.

What I am unsure about is if I can run dual-channel on the two 512 MB module and single channel for the 1024 module at the same time, or if I must have 4x512 MB modules to run Dual-channel.

Any opinions or pro's con's would be helpful. I am not buying any extreme DDR.

My options are as follows:

Target config:

512 + 512 + 1024 and later add an 1024 more..

or

512 + 512 + 512 + 512, where I can but the last pair soon.

512 + 512 = Dual Chanel

512 + 512 + 1024 = Single Chanel

512 + 512 + 512 + 512 = Dual Chanel

512 + 512 + 1024 + 1024 = Should be Dual Chanel but not recommended as what I have heard.

2 GBs should be enough for today system, my recommendation is to just get 2GB and when you will upgrade your full PC, then go with 4GB.

Aha. I see. Thanks for the answer.

Well ,the I think I'll get to purchasing either two 512 or one really good 512 MB module for now... must check the prices.
