Need help upgrading ram

[hyg71886]

I have vista x32 ultimate and it is great. However when i run crysis, my ram ramps up to 91% and it hick ups. My question is, if I go to 2 more gigs of ram then I know windows wont show all of it but what part of the ram is being used for the system? I mean is the portion for my 8800gts (g92) veing taken out?

Also, are these to rams the same? This is the one in my rig that pcwizard shows

and this is the one i wanna buy from newegg,
http://www.newegg.com/Product/Produc...82E16820148210

are those the same? and can I get a 2gb stick or should i get 1gb?

All you need is DDR2-800. Do not aquire the DDR2-1066 that you have picked out because it will not be utilized at its rated speed.


And it will benefit you more to grab two additional modules so your board can continue to utilize the dual channel feature.

doesnt the ram i put in have to match the ones i have? I already have that pair in, its rated at 1066 but i run it at 800. Also will 5121mb be takin out for my vid card?

With a 32 bit OS, you will show anywhere from 2.75 to 3.5 gb ram in Windows when you physically have 4gb. Don't worry about it. Windows will use what it can. Yes, an exact match is always best.

ya thats what i did i expressed ordered the one with link. Can't wait
