Thank you to 3oh6 and fefox for a good explanation. I guess to that certain motherboards would utilize ram much better then others. I don't plan to do OCing right away once I build my system (first time build) but it'll be good to start piecing together what my computer may have the capability of doing. The system to be in question is this.
Asus P5Q-pro ATX LGA775 P45 DDR2 2PCI-E16 Crossfire 3PCI-E1 2PCI SATA2 sound
GBLAN eSATA motherboard
Intel Core 2 Quad Q9550 LGA775 2.83GHz Yorkfield 1333FSB 12MB
G.Skill 8500 F2-8500CL5D 4GBI PC2-8500 4GB 2x2GB DDR2-1066 CL 5-5-5-15 240pin dual channel (thanks btw for explaining all that meant)
Western Digital WD1001FALS Caviar Black 1TB SATA2 7200RPM 4.2MS 32MB 3.5in Dual Processor Hard Drive OEM
XFX Radeon HD 4890 1GB 850MHz 1GB 3.9GHz GDDR5 PCI-E 2XDVI HDTV Video Card
LG GH22LS30 Black 22X SATA Lightscribe DVDRW OEM
all in a nice
Coolermaster cm 690 case, powered by a corsair 750W PS with a couple 120mm 3pin case fans to keep it cool, an extra heatsink may be in the works too.
I know this all doesn't pertain to RAM but does the choice I made match the system reletively well?
