i use 11.1 claymore version and my gpus are r9 390x as i read in 11.1 description i must get about 365
what's the problem?

6th GPU will not work, only 5 RX on windows 7.

maybe different brands get different results

I have 6 asus strix 390 oc in one rig and had to play with core oc while reducing voltage to get near that value

Not every card is the same, I fine tune each card with different oc and voltage because some won't produce more h/s past certain setting so there's no need to keep stressing the card, some get there with only 1120-1130 others only with 1150 core clock.

drivers also have influence and you need to check wich is best for your rig

Version 11.1
592 h/s

optiminer 1.4.0 card  5 - r9 390 -1755 h/s 

Ok.optiminer ~ 1770 h/s

my 390 are ~365 H/s and my 290x are ~340 H/s in optiminer, stock bios and overclocked.

Anybody could share rates on 290 Ref (390 bios moded)?

  holy-lee-crap

Had a lot going on over the holidays and being sick.....just had a chance to grab 11.1.
went from high 280's (intensity on the 6 version is like 4 on each card) to 660~670 steady!
running 1 - R9 270x 2GB and 2 - R9 270x 4GB and a HD7850 2 GB. The HD 7850 2 GB runs the video on the host computer as well.
Used to slow the vid down on that card but not now. Oh , and the 11.1 runs them at 6 Intensity.

btw - all stock clocks,win 7 - 64, 8gb ram, 15.12 drivers.
Not changing a thing, copied bat file from 6 to 11.1 and just let it ride on flypool.
This is amazing.

As always Claymore ....you rock!
