I noticed that any 1.5V 1600mhz DDR3 CL9 ram I put into the Saber-meow-kitty if set to _AUTO_ will run @ 1.48V. I have come to the conclusion that using a manual setting of 1.51500V will keep it at 1.5000~1.1510 > I think this is acceptable, if anyone disagrees please let me know because that is how I have it set and would hate to *blow it*, although when doing extreme OC I did push a dual stick of Mushkin Enhanced Blackline (997069) PC3-12800 9-9-9-24 1.5V close to 1.8V, I *thought* they were fried, but it turns out that Saberkitty simply does not like these sticks, as I ran them in another computer overnight using memtest86 and there were zero errors. And I really do miss that ram as I got them on sale They are one step down from the top shelf Mushkin Redline and I was getting FANTASTIC scores with them on my old GA970a-ud3 with a FX-6100 and I ran them in a 8-8-8-24 timing configuration without a hitch. I miss that build *tear*. In the Saberkitty ram list, Mushkin is hardly mentioned, maybe they will be supported one day, I can't wait, for now I had to purchase a set of BallisticX ram DIMM, which are on par with the Mushkins, but you just can't beat that Mushkin flavor of mmmmm *tear* and yeah, I am stuck with 9-9-9-24. If anyone knows of set of 2x8 Mushkin Redline that will work with the Sabertooth 990FX R2.0 I would LOVE to know.
