One quick question, someone who knows about RAM.

[pengwynman]

my question on RAM:

Is it possible to mix RAM modules that have different timing?
For example, i currently have these: http://www.newegg.com/Product/Produc...82E16820211066
but i also want to get these (rebate *drools*): http://www.newegg.com/Product/Produc...82E16820227198

existing modules: timing is 5-5-5-18, 1.8volts, CAS latency is 5.
new modules: timing is 4-4-4-15. 2.1volts, CAS latency is 4.

will having 4 gigs total, two of the old and two of the new, cause any conflicts or instabilities? they're both 800MHz DDR2s.

you MIGHT be able to make them work ok with the slower timings and higher voltage :P i wouldn't risk it, just get 4 (or 8) GB of the same thing, ddr2 is way cheap right now

To see if your computer is running 32-bit or 64-bit Windows, do the following:

1. Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.
2. Under System, you can view the system type.

Corsair is calling PC2 6400 because it is DDR2 memory. I figured this out by the way they named the DDR PC 3200 memory.

I believe most (if not all) of the 6400 rated memory is DDR2 so this should not be a problem with your motherboard.

i realized stating CAS latency is redundant. anyway.. thanks for the info. i'll have a look at other offers. yes prices are dropping but i'd like it to drop just a little more! lol

They will all run at the CAS5 speed but ram is very tricky that set up might work in 10 computers in a row and then not work in the 11th. Also differnt voltages is bad news for sure.

you get the rebate when you buy the motherboard and the memory together. if this is what you are doing than buy 2 sets of the SLI memory.

the timing should not cause any noticable performance loss. both memory cards will work in a normal 800 mhz motherboard but only the sli memory will work properly in an SLI motherboard. if you don't have SLI than don't buy it.
