I ordered more RAM for the PC, lately when I'm doing stuff like copying, converting video, extracting, downloading... together, my memory usage goes up to almost 100% and the PC almost freezes. I checked today and I saw that the RAM dropped a lot in price. I go now 2x4GB Corsair for 50€. It's the Corsair XMS3 DDR3-1333 CL9 (9-9-9-24). My 2x2GB RAM I bought with the system were almost 150€.

Perhaps I can even fit the new ones next to the others, and keeping also the old ones, remember there was the problem with one RAM slot being blocked by the CPU cooler, making RAM with bigger heatsinks not fit. This new RAM doesn't have a big heatsink, so perhaps it will fit.
