Your system has four RAM slots, so if you are currently using 2x512-MB sticks, you can add two more. See this Crucial recommended memory upgrade for your 4600 ($64 a piece, very good price).

Thanks for the fast reply. I will do that.

thanks again for you help and input.

Have a great day.

Since your Corsair RAM is PC2700, you'll want to match this, so get the Crucial DDR PC2700 • CL=2.5 • UNBUFFERED • NON-ECC • DDR333. Check the CL of your Corsair and make sure it's also 2.5, then you'll be all set.

I wish i went with crucial the first time. Yes i have two 512 chips but the brand is corsair if i get crucial to fill the other banks, will they work with the corsair? It has to be matching pairs btw. That's what i'm not sure about if using two differant brands will work or be compatiable.

thanks for your imput

oops i just checked my corsair, it is a ddr 400 pc 3200 so do i get the same if i want crucial?

thanks

Yes, get the DDR400 (same as PC3200). About the same price.
