Just installed a brand new Sapphire R9 390x Nitro. Install went flawlessly, cleaned out all drivers beforehand and downloaded the new Crimson 16.1.1 drivers and installed. Benchmarks run alright, Firestrike 1080p gets around 13100 or so at stock clocks of 1080/1500. However, I've noticed some WEIRD issues with the clocks and gpu volts dropping in MSI Afterburner and GPU-Z, so I investigated further. While running MSI Kombustor, it looks like the VRM1 temps are reaching 88*C after just a few minutes of testing. Core clocks are barely hitting 65*C under full load, and VRM2 never passes 62*C. But 88*C VRM1 on stock volts, stock power level, stock everything else?? Is this normal?? Can anyone else with an R9 390X run Kombustor or OCCT and let me know your stock VRM1 temps? Do you see any voltage drops (like say from 1.039 stock volts to around .998-1.011)??

If it matters, I'm currently running a Rosewill 750w 80+ bronze single rail, both PCIE 8 pin connectors, which should be way more than is needed for a single GPU and one OC'd I7 2600k. GPU-Z shows the card is pulling around 372w in max under Kombustor, and only 290w-310w out max at stock volts and clocks. If I push the power limit up to +35%, the core clock seems to stabilize, but the VRM1 temps rise even faster! What the heck? Is this card bunk at Sapphire's stock OC? doh.gif
