The advanced chipset features page is hidden. You have to press CTRL+F1 to open up this menu from the CMOS setup mainpage. Over this page, you can set the DRAM timing as AUTO or MANUAL. In Manual mode, you can set the ram timings. In our case, we ran our Corsair XMS3200 at two different settings.

1) CAS 2. 2-2-5 and
 2) CAS 2.5 3-3-6
