A8n-sli prem Bios settings needed.

Your board supports DDR 400 RAM, which is what you have.

The memory should be installed in the blue slots, A1 and B1. This means one slot is empty between the modules.

This board and BIOS has an interesting feature I've not seen before - you can set POST/BIOS messages to play sounds or your own voice to tell you what's happening or when errors occur. I guess this didn't catch on!

Your BIOS does have some RAM timing/latency changes available. But you may not need to do any of this. The AUTO setting in place may be doing just fine. Here's what I recommend.

Get the program CPUz from www.cpuid.com Run it and click on the Memory and SPD tabs. In the Memory section, look at the numbers for latency and compare them to the 3-3-3-8 that Corsair secifies. If that's what's shown, you have nothing to do. The numbers listed in the SPD tab should show you the same info under the listing for 200MHz - that's doubled to 400 by DDR RAM. The SPD is the info on the RAM modules that tells your BIOS how to set the memory. So if the SPD matches the Memory tab settings, you're in good shape.

If the results of CPUz show the correct timings, you're all done. If not, post here and we'll explain further. And let us know if your computer ever talks to you!
