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

[Gasotard]

This is kinda misleading.  ZCASH DEVS and backers receive 20 % of coins.  20.  %.  Of coins.  For the first 4 years.


Sure after 4 years it goes down to 10% overall apparently !  But for what we are concerned with, the first 4 years, they get 20%.

That is right. They might stop developing the ZCash after 4 years as they will not be paid by the coinbase.

it seems to me not so much profitable.


Zcash 24 our 380 h/s = $15.45

ETH 24 our  350 mh/s = $26.39

ETHC 24 our 350 mh/s = $24.03

if for cards 470 480 380x 390x do not get to 100 h / s to not see well card

Damn Semprons, should of got some FX instead during the Litecoin boom

I feel your pain :/

Athlon x4 also has very bad performance on this algo......
Not sure why this happens, but I believe it is due to the poor optimization for old AMD CPU architecture.

I'm curious, what are the unmodified values for GPU_FORCE_64BIT_PTR, GPU_MAX_HEAP_SIZE, GPU_USE_SYNC_OBJECTS, GPU_MAX_ALLOC_PERCENT, GPU_SINGLE_ALLOC_PERCENT or is there a way to reset them to values before setx command? I ask this because I'm currently mining with my daily pc that i play games etc. Would any of these commands affect gaming etc. negatively?

I guess they are documented in the AMD SDK and by default they are not defined. Unless you know defaults may be better to remove those variables from the global environment (see advanced system properties, I believe, they can be found and deleted there if were set at least once).

I can't say about affecting games, but for few known to me systems setting GPU_FORCE_64BIT_PTR=0 resulted in Calymore's ETH dual miner crash with RX470 cards. So I used all them but removed after that. On some other systems setting this showed me 3GB of VRAM for 380X and RX470 card instead of real 4GB.

So in short, yes, I would remove all of them and use in the form of set (not setx) only those that really affect mining performance (by testing on a particular system).

Your equihash rate is way too low. If done right it should be double of what ethash rates are.

I don't know why everyone is getting their panties so wadded up about this. ETH developers had close to 72 million coins already pre-mined when mining first started, so that represents nearly 84% of the almost 86 million coins available today. ZEC developers and investors will not get their full reward for 4 years, whereas I don't hear anyone concerned about other coin developers running off. Their investment will only grow as they continue to develop it.

To me this is one of the more fair launches I have seen in that they don't get insta-reward but have skin in the game as well. The first 4 years is what usually makes or breaks a coin anyway, so I see that as a pretty reasonable timeline.

v2.1 with -i 2 has given me a nice boost on R9s and 480xs

[Beachguy]

Just switched my 4 gPU rig to Claymore's V1.

MSI 7850 Twin Frozer 2 GB handles vid duties (intensity 15)
MSI R9 270X 4 GB
MSI R9 270X 4 GB
ASUS R9 270X 2 GB  

AMD driver 15.12 setup per claymore's guide. nothing fancy or over clocked.
Total runs stock and cool. pulls 123~125 sols.
Have owned a long time and mined ethereum with Claymore from day one.

Mining flypool.....Claymore rocks, didn't consider any other miner until he brought his out.

That is about right. For my AMD R9 390, it can do 30MH/s. For the ZEC, it can do 60 slol/s or 30H/s. 1H/s = 2 Sol/s.

it gave me 52+ on reference RX480
great

[forzendiablo]

280x gets 49-50 sols on -i 2 with 15.12 drivers

Only found info about GPU_MAX_HEAP_SIZE. I think it's 50 normally according to AMD SDK but it doesn't matter, your proposed method makes more sense. I found environment variables in advanced system settings and will make changes according to this info. thanks again for information!

Nearly correct. But strange, all my AMD R9 390 do 64 H/s each!  

Everything that counts are solutions/s, and meanwhile this number is mostly called H/s. (not like the original zcash miner which used the term H/s for I/s - which produce NEARLY the double number of solutions)

Claymore's miner also shows H/s for sol/s.

60 on a r9 390 (not x ?)  mine does 56-57  what clock you run at?

in total i do 410mh on ether and 860 on zcash (r9 270 has very good speed, close to 380's)

[crazyearner]

using defualt 0 or 1 works fine -i2 kills my cards and lags my system out even tho i2 runs for a good few hours still getting same speeds as -i 1 or setting at 0 default

Setting GPU_FORCE_64BIT_PTR=0 allows access to 32-bit address space of memory ~3.8 GB, while GPU_FORCE_64BIT_PTR=1 allows access to 64-bit of address space. So yes in order to utilize all of your GPU memory your should leave this set to one.

I think the main benefit to setting this to 0 for mining was that it cuts the required number of clock cycles needed to access the memory in half, thus improving (in theory) mining speed. Since most algorithms will fit within 3.8 GB of memory, for dedicated mining rigs it is set to 0. For gaming rigs or dual purpose (mining/gaming) with more than 4 GB of GPU memory, leave it on 1. I think the performance gains are minimal if noticeable at all.

52-55 on reference RX480 with moded bios, 90 minutes running stable so far, let's see what will happen overnight.

[adaseb]

It pretty much doesn't matter which GPU you have, they are all the same speeds.

My RX470 is 45Sols and my $20 Radeon 7850 is 30 Sol/s

[Bare]

Hey guys!

anyone has (Sapphire) FURY (X)?
I wonder what hash speeds you get with fury, possibly non X version!

thank you guys very much!

you mean it doesn't matter what bios I use right?
