It looks like only people with R9 290/390/280x remained on ZEC All others moved back to ETH
All others moved back to ETH Whats wrong with dwarfpool?
I am getting error message after every 1 hour saying "Cannot find job for 10 minutes there is something wrong in the Pool"
Any one getting same error?
Also lots of rejected shares

as well for me...
Well, now what is the Best pool for ZEC?

If you're in Europe change the dwarf server to the RU one - for me, after 10h, rejects there are at 0,15%
- updating catalyst to the latest version
dont bother trying the latest 16.12.x (relive) driver it drops hashes by 5-10% according to posts.
stick with 16.10.x, 16.11.x or so (i have 16.11.15, goes fine with my rx 470).
if your rig has only older 3x0, 2x0, 7xx0 cards best just to stay with 15.12. my 380/390 rig runs 15.12.

It seems there is a patch for the Tahiti Memory Timings which seems to increase the speed. Now, this is all a bit technical for me and I don't really know what it does exactly, but the results look promising. This only works for the Tahiti cards though (HD7950), like mine.

if youre uncomfortable flashing cards, be aware you can brick them fairly easily.
got any old cards to experiment on?
btw flashing cards seems to benefit eth mining more than zec. also a flash that may help one coin may crash with another. so if you will switch coins often it can be a double edged sword.
I'm running on 15.12 atm, which is OK. So I won't change my version. I do not have an old card to experiment on. But I won't flash the cards because I have a dual boot system where I mine XMR, ETH and previously ZEC in Linux. If I flash them, I might not be able to mine anything else anymore. Also, I have never flashed a GPU before...
EDIT: I got my catalyst version wrong...

The majority of cards I have had actually DIE have been HIS AMD cards.
The issue hasn't been the chipset - the issue is the CHEAP SLEEVE BEARING FANS they use on most of their cards.
so you would not recommend to buy a HIS HD7990 gpu? Is this brand possible to undervolt? (not like gigabite, where you have a limited chance to undervolt if even possible...)
thx for your reply
If it's one of their blower-style IceQ cards, should be good - they used a high quality Ball Bearing design on those.
I don't know if their higher end cards used ball-bearing fans at any point - if they DID upgrade to using high quality fans should be OK.

16.9.1/16.9.2 also seem to work fine for mining, though I'd recommend 16.10.1 for WQHL compatability + ability to used modded BIOS on RX series.
Pre-terrascale stuff you have to go with 16.9.2 "legacy" for it to work at all IME (15.7.1 does NOT work, 0 hashrate issue), otherwise 15.12 remains the "goto" version for pre-RX series cards IMO.
Hello friends,
I have 5X Sapphire nitro rx480 4gb on win 8 , the latest driver 16.12.2 , no overclock no bios mod.
When start ,all cards run at 200 h/s but after 5 min slowdown to 180-190 h/s.
I try few combinations 1395/2195 , 1306/1900 but no result.The people report 240-250 h/s for those cards.
Can you help me please with proper settings and driver version.
Thank you very much !

I will release new version in 1-2 days. Not all cards will get speedup, but at least Hawaii and Polaris will.
Will you gives us a heads up on the Polaris power consumption increase (if any)?

I did some tweaks on both of my Tahiti (HD7950) cards and I get around 200H/s per card. Makes 400H/s in total. I'm pretty happy with these results.
Thanks Claymore for this great program. Keep up the good work!

I did some overclocking to make sure both cards would yield the same results in Catalyst 15.11. I increased the GPU and memory clock of one of the cards. As you can see this gives me 200H/s per card.

I've been thinking of trying two more things to increase the H/s:
- updating catalyst to the latest version

Forget Polaris, Tahiti is king! Polaris is more efficient.

i get this speed from clocking 1050/1500 and running intensity 6.. no secret. have had use a bit more voltage in bios since last claymore version though.
Dear Claymore, I know you're very busy, but I would just like to draw your attention to my post on the Cryptonote Thread. THX.
also how i connect at spool with 2% fees and not 2.5??
?Quote
Pool supports Claymore SSL/TLS mining. All previous ports are compatible. Just add "ssl://" before the hostname at commandline
fuji core
doe not speed up?
ALSO ANY STABLE ATI DRIVERS expect ati 15.12 and 16.9.2???

Maybe some of you know, is it possible to use Claymore's manager to manage mixed Zcash, Eth/Etc & Cryptonote miners?
You can do that.
