RAM support in Intel D975XBX2 motherboard

Hi. Well my question is: i have a d975xbx2 Intel motherboard with an Intel core 2 quad Q6600 processor and RAM DDR2 553 Corsair. And i wish to upgrade my Rams memories. But i doesn't have idea if my PC supports PC2 (PC2 is the same as DDR2?) And my question: The Kingston HyperX - Memory - 2 GB ( 2 x 1 GB ) - DIMM 240-pin - DDR II - 800 MHz / PC2-6400 - 1.95 V - unbuffered - non-ECC works in my PC?

Sorry if i didn't explain me well, the English isn't my natal lenguage.

Thanks you for all your answers.

That particular Kingston set wouldn't be your best choice. Your MB specs are 1.8 to 1.9 v for memory. The Kingston website has a good search function, just input d975bx2 (from the pick list) and you'll get a whole page of model #s. The bx2 can also use ecc memory, but it will cost more...

Hi again. I am specially interested in this RAM http://www.amazon.com/Kingston-KVR [...] 856&sr=8-1

Then, it will work in my computer?

Thanks you again.

It will work, but it is only a single module. This model no. most matches your original request. KVR800D2N5K2/2G (Kingston's matched pair kit model no.'s always end with K2)

And yes, for all practical purposes pc2 = ddr2.
