DFI NF4 BIOS Memory Guide

Recommended Posts

I'm not 100% sure if this is the right topic, but I have a question. I have this mobo, and I used to run on 1GB of memory (2x512, OCZ extreme series, 2-2-2-5). I just decided to buy another GB (2x512) of patriot ram(2-3-2-5). I set Command Rate to 2T, and increased the voltage to 2.8V(thats OCZ voltage, patriot runs at 2.6V). Now when i go to Control Pannel -> System it tells me that I have 1GB of ram. When I open everest it still tells me that i have 1GB, but it shows 4 sticks of 512. It's kind of weird, is it because some AMDs aren't really compatible with 4x512 setup or is it something else?
