I have a question about the operation of my rig and one about mining on flypool if anyone can shed some light on them it would be appreciated!

I am mining with two cards a Sapphire r9 390x 8G and a Sapphire r9 Fury 4G (I like Sapphire cards), using 15.12 drivers, and the "updated" Claymore 12.2 (Thank you Mr. Claymore)!

1. What I notice is that in watching Zcash manager that the hash rate of the cards varies by 10% or so. the r9 fury from 408-449 (running at -I 7), and the r9 390x from 804-845 (running at -i8). I've played around with the intensity settings and these produce the best "average" hashrate in my rig. Is the variance due to mining difficulty? Is this normal?

2. When looking at Flypool's payout statistics, I notice that some blocks are "missed." It will say payout "to block" 74157. the next entry will say payout "from block" 74159. There are usually 2 and sometimes three blocks missing during each payout. Anyone know why?

Any thoughts or help is appreciated!

Thanks in advance.

Just a question cause I feel like drop kicking this miner sometimes I can't seem to get the rates others say I've tried all sorts of drivers win 10 and 7 I've tried different -i settings with benching at different clocks my 290 is at 310 or so my 390 I'm only getting 390 and 255 on my 280 so the first is how are you getting 804-845 because I have 15.12 drivers and updated 12.2

Does any you have any suggestions for me win7 15.12 drivers updated 12.2 390 hash 390 -i 8, 290 hash 310 -6, 280 hash 254 -i 5 all stock clocks I tried different drivers and -i I also tried over clocking which doesn't seem to help and -powlim 20 also when I try -i 8 on my 290 all cards go half speed I don't no why could the riser be causing this thank you for any help
