Hi, I currently have a pretty ancient computer, its a HP multi media, exact version -> HP-COMPAQ Media Center PC m7100n series. Anyways its pre made, didnt do much except place a 9800gt 512mb card in there for gaming purposes ofc. However for example i can play crysis/crysis warhead but on lowest graphics, its rediculous on how i have a 9 series nvidia card and i can only play on low, i mean i can go a lil higher on graphics but it slows down and is extremely unbareable to play in. Anyways im guessing maybe my ram is the issue, or my GPU or CPU. I currently have 1gig ram, 2x512 DDR2 ofcoarse, and i have 2 sticks 128 each hitting 256 together, wich i found these from my older pc. Now adding these 2 cud hit my ram around 1.3 wich is better than 1 ofcoarse. My question is will these 2 sticks work? They are... Kingston valueRAM KVR8TEX16-8/128-IS. Im not too sure if they will adapt and work with my pc right now, my sticks i have in my pc right now are just thin green chips, while these other 2 older sticks are the same but with a little silver peice attached to it. My pc does have 4 slots, 2 used from the 2x512, leaving 2 more for these 2 guys i have... So would they work on my pc? Thanks in advance.
