Hi, why the hash rate fluctuations? haven heavy or v8 on 4gb.... most fluctuate much..... on 2x 570 and one 560, the hash rate fluctuates on them as if its linked..... Multi hash not really much influential, however that 0.33b5 is Really fast..... samsung 8gb rx 470, haven, 1130 h/s etc. But some other GPUs are very low rate although they have good timings multi hash 944x2 , 8 work size on heavy 8 gb works but some doesnt like it..... dropping to 960+896 or even 896X2 doesn't fix much

I have up to date windows, fresh reset, 18.6.1 drivers..... more than enough virtual memory but only 4gb of ram. windows up to date. slots are 1.1 pcie tried going 2.0 yesterday , didnt notice much difference.

last i used was one of thos 0.31 copies that were slow in mining start, used to steadliy on hynix 8gb give 1090 h/s with 944 multi hash X2
