MSI 6600 Unable to alter MemMHz in HiveOS

[Aradial]

I have a mixed rig of 6 cards mining Raven that I recently put 2 MSI Mech 2X 6600 cards into. When I try to alter the Memory clock in HiveOS, it doesn’t change. Hive shows that I have configured it, but when I connect to the shell, its still running at the stock settings.

I can alter the Core clock and the power settings which change correctly, but the memory just wont budge. Anyone else having similar issues with 6600 cards? Any suggestions would be appreciated.

6600 is capped at 950 for memory for now.

Thanks for that, got an extra 1.2 MH out of each card.
