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

[forato]

to be honest i am disappointed the given specs 450sol for Nanos are no way near (between 395-410) i think voor Nano the speed is about the same as 11.1, Optiminer is quicker (atleast for Nanos)

Claymore made The same speed as optiminer.. I think he still can get more speed.

Good Work Claymore

Indeed speed is increased
Out of 6 RX 480's I am now getting 1860-1880 H/s
That is 310-315 H/s per GPU

The power consumption though is still High
Measured from the wall i get 1150 Watts

In comparison with Optiminer i get
1840 H/s That is an average of 305-307 H/s per GPU
But measured from the wall i get 940 Watts

So for the people that pay their electricity Opti ( In Linux) is still a better deal

PS. I am about to check Claymore in Linux also to see if i get better consumption

moded cards? what settings oc?

[nokapol]

Yeah I did not concentrate on tonga cards.
I can reach 430H/s on stock 390X. Or I can try to add Pascal coin to dual miner, or improve CryptoNight miner. Need to select.

Choose, please, CryptoNight miner

Yes custom rom

-powlim -7
-cclock 1350
-mclock 2000
-cvddc 1110
-mvddc 1000
-i 5

[issie81]

"-powlim 50" option + drivers 15.12 or 16.3.2 is the solution.

yeah but doing powlim 50 makes my VGA 16c hotter.. 61c vs 77c (still going up)
stressing the videocard that much for not even 10% is way to much

[fronder59]

miner work about 4 hours and stop mining because miner can't connect to DevFee port.
my pool is coinmine.pl and ssl port doesn't work, only stratum port. 

Tahiti cards give me 320-325 H/s

[daviez777]

card  : 3    290x

claymore 11.1    320    320   320

claymore  12.0    360    360    180 

Why ?

same problem here...but with 7990...

Try to reduce your -i,
I had this problem at first and solve it with reducing -i 8 to -i 7 with Furys.

Temps/power is lower but speed is about the same as optimizer. So for those that pay for power, it is a nice improvement. in my case that is

[kinsik]

For mixed rigs Fury + RX4xx you won't be able to get full speed from Fury because latest good drivers for Fury is 16.3.2 and they don't support Polaris. 16.6.2 and higher support Polaris but they cannot provide full speed for Fury.

Thanx for response Claymore. Will try to use 16.10.1 as suggested by nd see the results
Still it is not clear why ASM option does not work for Fury under 17.1.1 and shows 0 sols?

[Etherion]

ASM does not work for R9 Fury with any intensity on 17.1.1 driver. Is this expected?

For the Fury's i would return to 16.3.2 drivers

This is not possible as it does not support RX series and i have a mixed rig.
Still is there anyone that uses different drivers or have mixed rig either?

Bad idea to mix 14nm cards with 28nm cards.

[rpg]

@claymore

You should make the -li 1 default. It does have a major impact on temperature and I guess power usage with no meaningful decrease on hashrate. In fact Tahiti and Hawaii have no hashrate decrease at all. Ellesmere shows a decrease of 4 or 5 hashes.

Running 470-s, 290-s and 1070-s in the same rig, no problem at all.

Wow what a nice bunch of idiots around here, asking for a pascal dual miner. You will kill the coin before you can make some profit, and the power consumption and heat would kill the cards faster than the ETH dual miner does. Dual miners squeezes the card in such way, that they last 10 months at least. I had to stop using the dual miner functions because the heat screwed 3 of my cards.

No pascal dual miner, it would be great to improve the Cryptonight miner. And if you want to release a pascal miner, do it only to improve the pascal mining process, not for dual mining. Don't kill a promising coin right now.

That's right, dual mining requires increased amount of electricity energy and generates tremendous heat. Fans work much faster and reduces their life rapidly.

lol that the dumbest thing i have heard if u killed your cards next time dont run them blazin hot or buy better designed card = better components

Pretty sure he is making stuff up.

Dual mining uses like 40-50 Watts more on a 280X. So it uses 250 Watts instead of 200 Watt solo mining ETH.

Back in Scrypt LiteCoin days, each 280X used 350 Watts and we were all fine.

On the newer RX cards, I think dual mining uses even less power.

 I have a miner 6 x SAPPHIRE RX480 RX480 NITRO OC + (default clock is 1342  for the GPU). Miner consumes 975 W (for ZCash) with a speed of 1200 MHz GPU. If I use default clock then consumes 1255 - 1325 W. Add dual mining and sees how much to consumes. I am this is measured with an instrument "energy meter". This is total consumption from the wall with power supply Antec High Current Pro Platinum 1300. One thing is watch consumes energy with GPU software and the other thing is to measure actual consumption from the outlet (or as some say - from the wall). Also, at the same rig, using the SG Miner for Pascal, electricity consumption even in 1575 W. Imagine then the consumption of dual mining ZCash + Pascal. People, take the instrument in his hands, and then you can talk. However, you use modded BIOS, but I do not.

I dont know about it. Tried -li 1 and it does really improve temps while keeping the hashrate the same, but now pool shows much less that before...

Did you experience significantly lower temperature and/or lower power consumption? I never used low intensity mode and can't test my rigs now with "-li 1" parameter.

[Claymore]

I can confirm bug with wrong hashrate if you use "-li" or "-ttli" options. These options add delays after every GPU round, so GPU is free for some time and therefore it becomes cool. But v12 measures GPU round time not including these delays so you see same hashrate. I will fix it in next update. This bug was added during porting miner to Linux, I don't remember exact version number.

I have been experimenting with all the -i switches to lower down intensity/heat without too much impact on hash, and I got the same results like the above.

-li 1 gives me more less same hash but temps are down (not great as great as XMR mining, but good enough temps reduction).

My Nanos and 390s are doing very well with v12 on Linux.

I left the RX480 mining on ETH to compensate the drop in ZEC profitability.

It will be great if we can have an update on your XMR / Cryptonight miner.

XMR profitability is better than ZEC, and slightly lower than ETH.

Afternote: the hash does gets lower over time -- so -li will impact hash as per expected.

[IOTUSA]

For me v12 is slover than optiminer. 4x r9 270x 740 on claymore while 780 on optiminer.

Ver 12 is far more heavily tied to ASM and running ASM correct drivers than earlier versions.

[cryptowhat]

My fury dropped to about 200 hash on -i 8, 300 hash-i 7, and increased to 420 hash from ~400 on -i 6.

I was hitting 400~ on 11.1 on -i 8.

Thanks for the work clay

This is on win7 15.12

hmmmmm Actual submitted shares 100 hash. Went back to 11.1.
