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

[rospotrebpozor]

Hi all

I am having problems with one of my rigs and need some help. I am not new to mining, nor to this thread (just never needed to post before), but I certainly won't pretend to be an expert either. The rig I have an issue with (runs 3 x Sapphire Nitro+ 480 and 1 x 470) has been running well for about 7 months or so. It was running on V12.5 without any issue, however it crashed the other day and hasn't worked correctly since. The machine runs fine, Claymores V12.5 and V12.6 are both acting the same, when I start mining it recognises all the cards etc but then it mainly lists incorrect data, line after line. Please see the screenshot.
Is someone able to point me to the route of the problem?

Thank you

identify gpu3 and test it separately.

What hashrate are you getting with the 460 cards?

519 h/s

Not possible with single 460 cards.

This thread is huge so my issue might already have a solution. I configured this version for my HD 5700 1GB. I know it's old and not that powerful, but it's what I have for now. When I start it, everything looks good until the starts actually attempting to mine,  I am getting an error message saying GPU #0 returned incorrect data: random 6 characters in all red. Tried rebooting, clean uninstall of drivers, reinstall latest AMD drivers, tried 15.12 drivers (weren't compatible with my video card) still not working.  Anyone else see this and/or have a fix?

not sure if anyone replied to you yet, but I've not had any luck with getting 5000 series cards to work with zec, keccak and cryptonight are all I've had working, but claymores cryptonight miner was a bit buggy and he doesn't maintain it anymore for some reason, Keccak was going about break even earning on my 5670.

is block chain driver good for this miner or old crimson drivers??

You can use any driver with this miner... The latest 12.6 version works with the new API of "amd blockchain beta" driver, however there may be some issues with voltages and stuff... so if you have older polaris cards you may opt for something like 16.11.4 with no bios sig check and watttool fully working

That is right. I use the old drivers such as 15.12 or 16.9.2 for ZEC mining.

Difference is not noticed. On my RX480 310-315 h/s

I will use the old drivers. At least I can control the voltage etc.

Yes, I'm just saying that the hashrate did not change when using the blockchain-driver.
OverdriveNTool work with last AMD drivers.

hi guys.

sry i'm a newbie to this.
have tried to get the "Claymore's ZCash AMD GPU Miner v12.6" running on my win10 machine just for testing with following options:


GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

ZecMiner64.exe -zpool ssl://eu1-zcash.flypool.org:3443 -zwal waaletIDY.test -zpsw x -i 3

but it only says unknown options and unspezified pool.

can you please give me a hint.

i'm having a geforce 920M if it helps to resolve the issue.

thanks

Mining on a laptop is not recommended.

hi

i'm a newbie to this.


just started mining and have newbie question

when i was mining ethereum (same set, same gpu's, same everything) i was getting 26 Mh/s

now i'm mining zcash (same set, same gpu's, same everything) i'm getting 600 H/s

can some one explain it

thanks

https://whattomine.com check this. Different coins/algorithms different hash rates.

What driver to use for GTX 1060 6GB?

Thank you!

Why I'm getting this error everytime?

08:01:58:852    2b30    Cannot get Overdrive capabilities for adapter 0 (error -8)

My GPU is AMD R9 M370X. Optiminer Zcash works fine.

I'm using this variable:

GPU_MAX_ALLOC_PERCENT = 100;
GPU_FORCE_64BIT_PTR =1
GPU_MAX_HEAP_SIZE=100
GPU_USE_SYNC_OBJECTS=1
GPU_SINGLE_ALLOC_PERCENT=100

Does this miner shows rarely output hashrate? How can I decrease recheck delay? Or did it show rarely because of this error?

Why 16.12.2 as recommended driver version, since that is one of the "doesn't support BIOS modded version" drivers?

 I'd recommend 16.9.2 for RX 4xx series, don't have anything more recent to test on - though the 16.10.1 and 16.9.1 versions also worked well on the RX 4xx, 16.9.2 seems to offer better support for older cards and matches the hashrate almost identically to 15.12 on R9 3xx and older GCN cards (though it's more of a memory and resource hog than 15.12)

 For Nvidia other than the 1080ti TitanXp and perhaps the TitanX, 373.06 seems to be the "go to" driver.
 The 1080ti and second-gen Pascal version of the Titan need something newer, 378.something as I recall.

That is right. My HD 7970 and R9 390 cards work well with 16.9.2.

[QuintLeo]

Some of my testing on 16.9.2 a few months back included one each HD 7750, HD 7870, R9 280x and I think R9 290, as well as a couple of RX 470 cards.

 Given the bloatware status of the entire Relive series, 16.9.2 is my go-to version for RX series cards (which unfortunately I'm pretty sure means I can't use RX 5xx series cards and Vega is Right Out).

this miner really rocks. claymore you are the god of mining
