I just finished building my Sabertooth Z77 and i7-3770K system using F3-12800CL7Q-16GBZM (4x4GB). It booted up fine with the latest 1206 BIOS and is running Memtest86+ V4.20 well. It automatically started by using the JEDEC settings of DDR3-1337 9-9-9-24.
Following some advice on this forum (unfortunately the search function on this forum doesn't work for me in either Firefox or IE8) I used the Ai Tweaker in the UEFI BIOS to auto-tune the OC parameters. After numerous automated attempts (very cool) it finally arrived at the XMP type timings of CAS 7-8-8-24, but the voltage stayed at 1.5V and the speed increased only slightly to DDR3-1360. Memory bandwidth increased only slightly from 17207 MB/s to 17499 MB/s.
It's not clear to me that the memory subsystem is really in XMP mode (I don't immediately see "XMP" in the BIOS).
I see in the latest QVL that ASUS runs most of your low latency sticks at 1.6V, but I don't see my set with the "ZM" suffix in there.
Do you have a recommendation as to how to get better memory performance without causing heat, stability, or short part lifetime problems? Thanks.
