ok so I've edited the CFG and still 600 is the max I can hit no matter the number of times I have tried going up/down, open/close.
Does this require a reboot to enforce the below?
[ATIADLHAL]
UnofficialOverclockingEULA =
UnofficialOverclockingMode = 1
AccessibilityCheckingPeriod = 0
Try this:
[ATIADLHAL]
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1
AccessibilityCheckingPeriod = 0
Or try ati tray tools, seems to work better for me. But with ATT I need to set default clocks every time before changing gpu/core clocks.
