I'll try to keep it short (which I always have trouble doing).
I'm building a gaming PC for my father and am not sure what kind of memory I should get. The PC's build can be found at the bottom of this post.
Here's the motherboard I chose - ASUS M4A78 Plus AM3/AM2+/AM2 AMD 770 ATX AMD Motherboard - Retail
Technical memory-related specs:
Number of Memory Slots 4Χ240pin
Memory Standard DDR2 1066*/800/667
* Due to AMD CPU limitation, DDR2 1066 is supported by AM2+/AM3 CPU for one DIMM per channel only.
Maximum Memory Supported 16GB
Channel Supported Dual Channel
So here's my dilemma. The CPU's integrated memory controller only supports one DIMM of 1066 per channel. What should I get? This machine is probably going to run Vista, or if possible be an XP/Vista dual-boot setup. I don't know too much about Vista, but I know it is a memory hog. I'm guessing I should get around 6 to 8gb of memory, but am not sure. How much memory should I have for gaming with Vista?
I was looking at this memory - G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Retail
If I bought 8GB of this memory, would all of the memory slow to 800, or would half of it be 1066? My assumption would be the former, in which case I'm not sure if I should get 4GB 1066 or have 8GB of 800. Unfortunately, I do not see any 4GB modules of 1066 RAM to do 2 x 4GB, although I have not thoroughly searched yet.
Is the increased bandwidth even worth it, or will it not make a difference for my build? No point in going crazy if the bandwidth isn't going to be used,
Thanks in advance, and if you need any more info, please ask!
