I used bios P11 for testing. I know they added support for 4gb dimms, but didn't know if 8gb dimms would work. I couldn't find anyone who has used more than 4gb on the net. I had some 8gb sticks to play with and figured id give them a shot. It worked to my surprise. Im in the process of upgrading my X58 setup. I just got a vanilla 6 core 980 and wanted to beef up my ram too.

I use my PC as a workstation for Adobe CS and Corel and 6gb is just not enough. I have hit my limit many times before. I like to have all my programs running across 3 1200p dells, and have about 20 tabbed websites running.

Didnt have a lot of time to play with them though, timings are a bit week on 8gb sticks. My sticks are 3x8 1600mhz 9-9-9-24 1.5v PNY.

Still trying to decide if i should use the 24gb kit or use a 12gb kit at better timings. Someone will trade me for 3x4 Dom GT's 2000mz 9-10-9-27.

I will take some screens when I get a chance to play around more.
