2 GB Single Channel vs 3 GB Dual-Channel Asymmetric

[djdelarosa25]

One stick is a 2 GB Kingston DDR2-800 PC2-6400. I purchased another stick of DDR2 of the same brand, but different speed (PC2-5300 DDR2-667) and capacity (1GB)

 

Which would yield better performance, sticking with the 2 GB one, or adding the other one? I can confirm that the system boots up with the other stick added.

 

Also, 32-bit or 64-bit OS for this?

It will hurt the performance, but depending on what you are doing it probably wont be noticable. I'm trying to upload my DDR2 benchmark results now, but Imgur is crapping the bad again.

It will hurt the performance

Adding the 1 GB will?

Adding the 1 GB will?

It will drop the speed down to 667Mhz from 800Mhz, but with most of the older memory controllers(and even some modern day ones) the more RAM you add the slower it gets(more latency, slower speeds). I'm still trying to upload my test results, I'm thinking about abandoning Imgur...

Ok, I just uploaded the results directly to the forum. 

 

Here is 2x 2GB 800Mhz memory:

2x 2GB 667Mhz memory:

3x 2GB 667Mhz memory:

and 4x 667Mhz memory:

 

If the program(s) you use aren't memory intensive then you won't notice much of a difference, but in the case of GTA V I saw a 10-15 FPS increase since my GPU had to use the system RAM as cache so much.
