Well, it may be all isn't well for me either. Whist the clocks appear to hold initially, like when running heaven for 45/50 mins earlier, but then when gaming, on the overlay the clocks are normal, i.e: just shy of 1800 with 99% utilisation. When I stop and check the log, wattman then starts reporting some really odd readings, like spikes of 4000mhz core and 1400 on the hbm. Jumps all over the place. Doesn't affect gaming performance but does the same thing if I run heaven again. Doesn't cause any issue when running heaven. Just odd readings on the log.
All very odd. And annoying!
On the plus side, I had 1901mhz with 1101mv running for ages
