My Zotac reference 750 Tis perform better than my ASUS 6-pin models...Made me a sad panda...since the ASUS models were $10 more expensive. The ASUS MEM CLK's wouldn't OC worth a ****. The Zotac MEM CLK is much more flexible...just my experience.
BTW, Windows 8.1 x64 was causing my scalability issues...now getting 1740 kH/s on 6 750 Tis on the USB 3.0 x1 riser cable assemblies.
Is there a CLI for MSI AB? I need to automate my tuned over clocks for each card individually. I have all of the information in a spreadsheet, but still have to spend 1-2 mins manually setting and applying everything.
