Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[h311m4n]

Very small difference in hashrate with -i 4, I get maybe 5-10 hashes more per rig. Almostno change in wattage though.

[doktor83]

Can someone point me in the direction to mod the bios on the following for low power consumption or at least better than stock bios mining:

I have rigs with the following :

Powercolor red devil 1330mhx RX 480 8GB
Sapphire nitro rx 470 4gb
sapphire nitro rx 480 4 gb
sapphire nitro rx 480 8 gb

All will use powered risers 1x - 16x if that matters.


These are all about to get installed into rigs for minining and I want to set it right up at the start.

This version 6.0 is more stable than the previous.. like eth miner.. the hashrate don't fluctuate so much.. with the previous version the number go from 120 to 135 H/s (sometimes 140) .. this version the number go from 153 to 155 H/s... very stable..

Great job!!

i also noticed this, cpu % is also same.. Wonder what's the difference

~ 114 per card on R9 280x
~ 113 per card on 7970

Got about the same on stock 7970, while one with modded bios gives 137+ sol/s, peaking at almost 150sol/s

How are your speeds with "-i 3" vs "-i 4" ?

same

148H/s on reference RX480 is OK?

[doktor83]

yes

~ 115 per card on R9 290x
~ 114 per card on R9 280x
~ 113 per card on 7970
~ 154 per card RX 480

All stock settings

Thanks!

Seems odd. I get 125 sol/s on 290 (not 290x) with 5.0 stock

Great job..but still favor stronger CPYs ...have 15 sols more per card where quad core is then where dual core is

[safonov]

116h/s r9 280x norm?

[Cryptozillah]

280x ~125.5 ( -i 4)
470 4GB ~145 ( -i 4)
480 8GB ~150 ( -i 4)

470s almost kicking their big brothers asses.

Great update !

280x 120 sols... stock

"Great job..but still favor stronger CPYs ...have 15 sols more per card where quad core is then where dual core is"

Interesting.. I can't find any difference between G1840 Celeron and i3-4160 CPU (absolutely identical rigs with 6*RX470).

[CoolnQuiet]

will there be any more versions, or how much close are we to the max limit can be utilized by GPUs?  

[adaseb]

There is a difference between a cheap Sempron and i3 with the 470's. About 10 Sol/s difference per GPU.

ZEC - Total Speed: 653.924 H/s, Total Shares: 459, Rejected: 1, Time: 00:57
ZEC: GPU0 128.636 H/s, GPU1 129.055 H/s, GPU2 126.077 H/s, GPU3 127.874 H/s, GPU4 142.282 H/s

all r9 280x with -i 2

-i 3 or 4 did not make a difference

Doesn't look like these Pitcairns and Tahiti are going back to mining ETH anytime soon.

i want to buy some gpu for mining Zcash. . what is best ROI for mining this coin  ? AMD rx 480 or 470?
