Hey guys some REALLY good news for samsung ULV owners, i just got a new test BIOS, which I will see if I can post. I can do 2600mhz T1 cas 10 1.7v. 32M stable. Shoudl be new BIOS with the fix out for UP5 and UD5H. Just finished UD5H testing and all seems decent, UP5 testing now in affect. This solution will apply to users with 2-4 sticks, as we already know you can do 2600mhz with a single stick.
