AMD Athlon II x4 640 Processor 3.00GHz
I did some checking during my first post and noticed those "for AMD only" 4 GB DDR2 modules are a lot cheaper than the others.lucky for you yours is an AMD-based one (AM2+ mobo) so you can go with the "cheap" way: Buy the AMD-only 4GB DDR2 RAM sticks
In fact I realized their existence two years ago when I was planning to upgrade my old Core 2 Duo rig (now having Xeon E5450, Gigabyte G41 chipset mobo with 2 DDR2 RAM slots) to 8GB RAM, did some research and concluded these AMD-only modules were true to their words. That means I'd have to buy the expensive ones which were priced as if they were made of gold, hell 4GB DDR2 SO-DIMM modules are cheaperI did some checking during my first post and noticed those "for AMD only" 4 GB DDR2 modules are a lot cheaper than the others.
