Suggestion to buy 4GB RAM

[Kirt]

I have Gigabyte X38-DS4 and I am running Vista 64 bit. I am planning to buy 4 GB of RAM.

My question is: does it make sense to buy 4 x 1024 or should I go for 2 x 2048? In the first case, what I have to do is add 2 barrettes; whereas in the second case, I need to change my RAM.

Is there any difference?

Everything depends on your current timings. 2GB RAM are struggling to hold down timings, sometimes flying. And hence suffers from the loss of performance.

I'm 5-5-5-15 in 570Mhz (1140 instead of 1066) in Crucial BallistiX. If I take a kit 2 x 1024 with the same characteristics, could I keep the current perf then?

And as it does me to invest in a kit 2 x 1024, so is it a positive choice in all aspects (price and PERF).

It seems to me that it will be more difficult to achieve a good frequency ram with 4 x 1 GB rather than 2 x 2 GB.

I do not think you would have lost a lot of perf in 4 x 1GB and your portfolio would have preferred (even at the sight of the price of DDR2).
Example, I'm 4 x 1GB, CAS5 at 555 MHz, and stable under MemTest not really pushed to peak
