I also tried setting the power limit to +50% (at first in CCC, then in MSI AB), even tried setting fan speed manual to 100% just for the sake of it.
Sadly it doesn't seem to want to go to the proper minimum of 9xx MHz so I can raise my FPS above the current 17 FPS -_-'
Any tips, ideas or help would be much apreciated , I have searched this thread in which I saw someone else have the same issue but didn't find a solution to it.
Ah I had this problem earlier.
MSI afterburner in Unofficial mode doesn't work, all it does is set a maximum clockspeed but the clocks will throttle down when the core is loaded (granted the game/benchmark will still run at a steady 900ish mhz)
TriXX doesn't work because it only sets the maximum clock, it doesn't force 3D only clocks.
ULPS Disable didn't work for me, I don't think it solves your problem thought it doesn't really hurt to try.
There are only 2 foolproof ways I found around this though each has its compromises.
1. Custom Radeon Pro profiles. You can use force maximum 3D clocks on an individual game basis when you create profiles. The main advantage of this is that you still retain full idle and video clocks while still getting full boost. The biggest drawback to this method is you can't force 3d clocks AND do voltage assisted overclocking at the same time, since Radeon Pro uses the Overdrive engine (which doesn't support overvoltage), any overclock you perform after the game is launched will override Radeon Pro's settings.
2. Flash the ASUS 290X PT1T BIOS. This works like a charm, its actually a 290X bios but I was able to flash it on to my Sapphire Tri X 290 card with no issues. The beauty of this BIOS is it sets 1000mhz as the minimum state of the GPU at all times (i.e. PowerPlay has been disabled). You can then use a specially modded ASUS GPU TWEAK (which was borderline impossible to locate) to do your overclocking and overvoltage. The card typically boosts to your overclocked speeds 95% of the time and will do it for most games. Why the PT1T version? this one has VDROOP but it also apparently has some funky coding to prevent pre-boot blackscreens if your motherboard is picky about mismatched device IDs.
The biggest disadvantage to this method is that your GPU runs at 1000mhz all the time, no 2d or video clocks are present. I'm running this configuration on air at the moment with no issues so I can't imagine you having problems since your card is watercooled.
