Just to share what I've been observing with the "power spikes" and HWINFO64. Spikes seem to occur every 5-6 polling intervals (time = 100ms)

V9 (Intensity 8 ):

Fury Nitro:



I have the R9 Nano. The GPU will have flucuate between 0% to 100% power all the time, and then it crashes.

My Nano rigs got the greatest boost from v9 but some of them went as high at 350H/s then died.... died as in gone from device manager -- so hard reboot and reduced the intensity to 4. Some Nanos wre still coping at i=6

I think the "maximal" that Claymore uses the i=7 and i=8 to give that 1% additional boost -- maybe causing the spikes. I can only imagine he may be exploring deeper into the power architecture to get that extra boost.

i=6 is safe zone for me and I will set this as the gold standard for v9, else i=4 then i=0 -- last resort v8.

v8 is , IMHO, the most stable version of all. Well to be fair, v9 is labeled BETA....  Grin
