I recently bought a new computer and built it myself.

Motherboard: GIGABYTE GA-EP45-DS3R LGA 775 Intel P45 ATX Intel Motherboard
http://www.newegg.com/Product/Prod [...] 6813128344
RAM: OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory
http://www.newegg.com/Product/Prod [...] 6820227289

It won't run dual channel. I flashed to the most recent BIOS and a few other things but it keeps saying single channel. The RAM is in slot 3 and 4 (since 1 and 2 wasnt running dual). The slot colors are different. Computer is showing ram using 33% just for runnning Vista =/

Here's some screenshots of CPU-Z

You need to install the ram in 'same color' slots for Dual Channel capabilities.

Okay, done. But Vista is still running at 1.2 gigs of ram. Is that normal? And if you look at my CPU-Z is there room to improve the performance of my ram?

Yes. Depending on what programs you have running in the background.
Vista will use around 700 meg to well over 1 gig by itself, depending also on what it is doing in the background.
