lost radeon VII hashrate when we hit dag 379
amd driver 20.3.1
something peculier has just happened.
this may help vega and radeon vii owners
i updated my radeonvii rig to latest windows 10 called 20H2
then went back into updates and did the 20h2 optional update thingy.
it takes a few minutes and two reboots required
started miner - got 80 mhash per card - the expected reduced rate.
waited three hours and -
just now the rig stopped itself.
i restarted it and phoenix saying "unknown opencl version" but ive got my missing hashes back.
windows has updated something to do with opencl and the hashes are back. 83mhash per card
hmm
cant say i undertstand this at all.
 am getting shares - seems to be ok - no problems

i didnt update opencl - windows did itself.

dag 380 due in two hours wonder what will happen then?
