As I mentioned earlier, the OCZ DDR3-2000 SLI memory is designed for the 790i SLI platform. Well, there are two models of nForce 790i chipsets, the 790i SLI, and the 790i SLI Ultra. My test motherboard is one of the very few boards built with the 790i non-Ultra chipset. The Striker II NSE is designed to operate memory at DDR3-1600, but with some help from the techs as Asus, I have successfully run it at DDR3-1818. I've actually had it up to DDR3-1866, but it runs a little buggy at that speed.
As most DDR3 memory, the OCZ SLI defaults at DDR3-1333 to allow a rig incapable of booting at higher speeds to be able to start. Default timings are 8-8-8-24, and default voltage is the DDR3 standard of 1.5v.
The SPD chart shows settings only at DDR3-1186 and DDR3-1333, both at 1.5v. I was a little surprised that the EPP settings weren't there, but they may show up only when the memory is used on an nForce 790i Ultra board.
The memory was recognized by the BIOS as being SLI enabled memory, but was disabled by default since I'm not running the rig in SLI.
After flashing with the latest BIOS, and a few hours of experimenting, I found that my motherboard maxed out at a stable DDR3-1833. That is pretty much what I expected it to do, but there is always some wishful thinking. Special settings were: P1 Enabled, P2 Enabled, NB voltage 1.6v. I would not recommend taking the NB voltage over 1.5v without water cooling. The Asus Striker II Extreme 790i Ultra board generally requires bumping the NB to 1.5v to get to DDR3-2000, and I would imagine most other 790i Ultra boards do too.
