Sadly I had 2x1GB (2GB In total) DDR2 667 MHZ RAM sticks.
Apparently they have stopped functioning. So I bought a new MUSHKIN 2GB 800MHZ DDR2 Dual Channel RAM.

I tried playing APB Reloaded, had some lag with the memory, noticed it uses over 1.5GB in task manager, I was like wth, searched on google on why its using so much memory, and it looks like the game engine itself is an abomination.

Anyways, Desoldering/Re-Soldering is a good idea? Maybe give them to an expert to fix? Or Just throw them to trash can?
