s18000rpm

Recommended Posts

I want to upgrade my system RAM with a 2GB module, right now I have 1GB (2x512MB) RAM.

 

Details:

Present RAM: Corsair 1GB TWIN2X1024A-6400 running fine @800MHz in dual channel mode.

 

the upgrade option i have is -

2GB CM2X2048-6400C5

[link]

 

Other models are not available here. :mad:

 

My question - Will the C5 model work with the present memory module?

 

My PC Details:

Intel Core2Duo e4500 @2.2GHz, 800FSB,

Intel DG965WH m/b

1GB RAM 2x512MB @ 800MHz

80GB Hitachi HDD

Windows 7 Ultimate 32bit.

 

I get a lot of "Low Memory" warnings nowadays.

(check attachment)

 

m/b supports 4GB max in 800MHz mode, above 4GB will run at 667 or 533MHz mode.

none are "supposed to work" with what you have but some might. mixing ram is not supported or suggested. your OS will only support up to 3.25 gig btw.

if you really want 4 gig i suggest getting a 2x2 kit compatible with your board. the memory finder link is on your left.

good luck!

i dont want 4GB RAM, I just want Windows 7 & my apps. to run better :D

 

I'm buying a 2GB RAM, as i'm very satisfied with Corsair, I thought of using the existing RAM modules with new one.

 

timings & voltage - 5-5-5-15 at 1.9V (512MB) & 5-5-5-18 for 2GB

Anyways, I shouldnt even try mixing them right?

 

Then i'll sell this & buy 2GB module only :D

 

Which kit should i go for?

 

Value Select or same XMS2?

 

I'm also getting a MSI GTX 460 768MB graphics card. Which RAM compliments a powerful gfx. card?

if you use 3 sticks you will lose the performance of dual channel mode. really your best option is a 4 gig kit. the difference between a value select kit and an xms kit is only 20 bucks. use the memory finder link on the left to see a list of compatible supported ram.

a 2x2 kit is like 129.00US roughly and your system will benefit much better for even the 3,25 gig that will be available with your 32 bit operating system.

i personally dont see any super gains from just 1 2gig module over a 2x2 in DC mode.

 

just my .02
