Howdy all,

I get my new PC Parts next week including:

CPU - Intel CORE 2 Duo - E6600
MoBo - ASUS nForce590 Intel Edition
GPU - MSI 8800GTX
PSU - Tagan EASYCon XL 700W (Modular)
RAM - Corsair XMS2 DDR2-800 / PC2-6400 (4-4-4-12)
:trumpet: Happy about that, except for the cost - which is outer-worldly :inlove:

My question is, I have Corsair ValueSelect 2GB (2 x 1GB Dual Channel) PC-4200 DDR2-533, which runs dual channel on my current system. I intend on having the XMS2 running dual channel in my new system - will the Value select running dual channel in the spare slots slow down the system overall (being a slower set of ram) or will there be some improvements? :flowers:

Anyone esle got the 8800GTX? If so, what is your impression?

Cheers :thumbsup:

When two different speeds of RAM are conbined it will alway underclock to the slower module.

Recommendation:
Get the NForce680i
Also, if you're going to keep your RAM now, buy the cheapest kind that can go with that speed. Little bit smarter.

Sorry 680i is outside my budget! I'm looking at an extra $AU250 or so. And before you say anything, I can't purchase from newegg.com!!! :thumbsup:

I'm definitely getting the better RAM (DDR2-800 - 4-4-4-12)...

So DC3, you are saying that even though they are on different "Dual Channels", they will both slow to the slowest RAM on all four slots? If so, that sucks, but 2GB RAM is enough (when is enough enough though!?). Oh well, I guess I can sell them on eBay! Get back SOME of my money back at least....

Yeah, the modules also have to be the same in all specs in order to be run in dual channel.

As for when is enough enough, there are bechmark strudies with single core CPUs that show 1GB of RAM to be adiquate for normal applications. But if you're using programs like photoshop you will appreciate having 2GB. You can have too much RAM, Windows XP home will only support 4GB.

I'd still keep the other RAM.
4gigs DDR2-533 > 2gigs DDR2-800

No way - someone back me up on this!

2GB of XMS2 DDR2-800 PC2-6400 4-4-4-12 is better than 4GB at
DDR2-553 poor quality. By using the lower speed, I would be creating a bottle neck in my system, and overall performance would drop. 2GB is enough to run BF2, 2142, FEAR etc - the programs themselves only utilise around 1GB to run (and 300MB for background processes), then the graphics is processed by the Video card....

Well, that's correct. Since you only need a certain amount of memory to control all your programs.
My bad.

Just making sure I've got the right idea!
