Interesting...care to share your full command line?
 I tried exp too, and can'd do better than around 12.5
on exp or eth (have similar numbers for both), however I can
 reach dcr 360 with almost no drop on eth/exp performance
with -dcri 60 in command line

Edit: my mistake assuming everyone uses ETH for speed testing, but
at least I learned something new...EXP actually seems good option
for people with slow rigs mining to exchange wallets with big cap
on ethereum (0.5 on Poloniex, for example)

Epoch #22? When was that, 2 years ago?

You could still do it...if only your card would be 4GB version

...or maybe wait just a bit longer to score a hit

Because he didn't know its slow?

I only tried claymore, which is not optimized for Baffin yet, maybe some other miner performs better, though


Edit: I tried again because meantime I changed BIOS, this is better result, but still nothing
to write home about:

Using Claymore 12.5, old 7850/1GB card is twice as fast

With 15.12 drivers?

Did anyone tested different drivers for R9 cards? My vanilla unmodded R9 380 mines 20.5MH/s ETH + 330MH/s SIA with latest 17.6.2, but
I'd gladly revert to 15.12 if I'll mine more

I bought 4 from same vendor at once, and got 2 micron and 2 hynix...and no way to find out
as they're phisically the same

I think you can use it whenever, but you HAVE to use it for drivers to recognize cards once bios is modded

SRBpolaris editor seems easiest one to use:

https://bitcointalk.org/index.php?topic=1882656.0

For other RX cards people usually claim Hynix to be the best memory,
but for my cards Micron seems to be a bit better (but maybe it could
be its down to my lack of experience with bios modding, too )

Keep in mind that theres 2 versions of that card...one with Hynix memory
and another one with Micron

Its an AMD card...as usual, don't be surprised if it get 50% better result
after few driver iterations

There is also Gigabyte RX 560 card with hynix memory, this is bios for it:

Funny part is, it has strap for 2250, but you can't OC it that high
through Wattman

I wonder which version is better, one with micron, or hynix memory

Sshot or it didn't happen

Pity...good luck with next one 

New version coming soon?

Impatient RX 560 user here (hope that announced RX 460 ASM support
means it will work for RX 560 too)

Thats pretty solid hashrate, did you modify bios/overclock your cards?

I have another problem, claymore 9.5 doesn't recognize card as AMD one, so -asm mode
is not on by default...and I can't force -asm 1 nor -asm 2...maybe idea for version 9.6
