The RAM I took out was 2 sticks (dual channel) of 256MB Corsair XMS PC3200 DDRAM for a total of 512MB. The RAM I just put in is 2 sticks of 512 XMS Corsair PC3200 for a total of a gig of RAM. My first question is, would it be wasteful to put my 2 sticks of 256MB RAM back in? I have heard that for the most effectiveness it's better just to have 2 sticks in at once.

My other question is about setting the RAM settings. I'm not an expert on the subject so I'm extremely hesitant to change any timings, etc because I don't want to mess anything up. Stability's probably my biggest concern. However, are there any tweaks I can put in with minimal to no risk of something going wrong?

Thanks for any help...
 
I've heard that this is not true on P4's chipsets, but ill tell neway.


On my Lanparty AMD Nforce II Board, I can run dual channel with 2-4 stiucks with little to no performance loss.

Asi said im not even sure if its possible to run dual channel with more than w sticks on a P4 system, and if you can i dont know if it will be slower,

Sorry ic an't be of muych help,

Also, You would probably get a better performance boost from running 1.5gb single channel of RAM than 1gb in Dual CHannel


Also, W/o using that specific RAM, i dont know wut timings are best.
 
Here is your answer:
Here

DDR400 (1:1) Performance DIMM Configuration Single-Channel or Dual-Channel
1 4 DS Dual Channel
2 2 DS or 4 SS Dual Channel
3 2 SS Dual Channel
4 4 SS/DS Mixed Matched Pairs Dual Channel
5 Any DS Single Channel
6 Any SS Single Channel

Bad formatting is not my fault.
4 dual sided sticks is fastest, then 2 dual sided sticks (2x512) OR 4xSingle sides (4x256MB) etc.

You can run mixed matched pairs of DIMMs. That is, two of one type and size and two of another type and size, but the performance can be significantly lowered. In our tests of mixed pairs, performance decreased 22% to 25% compared to four matched double-sided DIMMs.

I went from 2 sticks to 4 sticks on my P4 system, and there was no perfomance loss, although they are all the same ram. (4x256MB Kingmax pc3500)
 
Dell box with p4 2.26 533 FSB two sticks of kingston 256 MB PC2700 and 2 sticks of 128 PC3200 for a total of 768MB. Memory bench marks are as good as another Dell box with only 2 sticks of 256 pc2700 ram.
