you are not ocing the Memory clock ?
...BIOS#1 is stock...even with no extra voltage via MSI AB, it will clock to about 1140MHz, but with MSI AB (and its 1.3v override) it will get to about 1220 & oc'ed memory (still stock voltage on the memory) of up to 1680
...BIOS#2 is 'custom', taking basically any voltage I want to give it for the GPU (within reason), though I have that at 1.35v which is not a problem with the heavy water cooling...yielding about 1240 to 1250 MHz, depending on app...memory as above at up to 1680
