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

[Blamsud]

For anyone with Radeon 7950 / 7970 / 280X who wants more juice out of ZEC mining you can adjust your timings.

Mine went from 43 Sol/s --->  52 Sol/s. Running at 1100 / 1575

THIS IS ONLY FOR HYNIX MEMORY H5GQ2H24MFR . I will post Elpida and Samsung memory types later.

Thanks for sharing . Plz share info for Elpida memory 280xs as it appier. Ive got some of them.

I've modded some Elpida 280x before but I can't find them. If you search this forum, a few months ago someone made some optimized bioses for 380x and he posted the memory straps for the Elpida's. They are somewhere there.

my 280x hynix memory is H5GQ2H24AFR

how to identify memory code?  i have 3 sapphire 280x toxic with hynix memory

You can go to the GPUZ and select the card. The memory type is displayed in the middle of the panel.

Not going to Happen

Has anybody noticed if this miner needs more PCIe bandwidth like the genoil miner did?

We're still not sure the PCIe bandwidth is a limiting factor, though it did appear to be a possibility with Genoil's miner. Genoil's miner was very CPU hungry too though. My Celeron and Pentium chips would be at 40% CPU load with Genoil miner, with Claymore miner they're in low single digits CPU usage. But certainly claymore's miner is much quicker for me on my 6 and 7 card rigs.

I'm getting almost twice the hashrate with my 7x 290x rig.

Oh I am sure the bandwidth was a factor. I had a 4x 480 with Athlon II X2 using PCIe 1x extenders.
26-29 Sol/s

Putting the cards into the x16 slots with no other changes
30-35 Sol/s

Claymore
41-43 Sol/s

Yes, I noticed the same. But only with Genoil miner it seems and probably something to do with the much higher CPU usage. So I'm not sure it's a limiting factor anymore.

Looks like right now if you have any RX 470/480

ETC PROFITABILITY = ZEC PROFITABILITY


Still more profitable to mine ZEC on 280x however.

Going by Nicehash and Whattomine data

ETH miners are already fully optimized, ZEC miners are at the early development stage.  

I still hope to get a lot more ZEC from my 480.

Pity ZEC price is plummeting...  

Yeah, now if everyone would stop using claymore's super fast and stable miner maybe the price won't dump so much  

A 480 does better..

Still doing good

Could anyone tell me how to mod bios for 290x and Fury x? I'm a beginner for modding bios. Thanks so much!!!

Firstly, big thanks to Claymore for getting this great miner out to everyone!  I know you mentioned that you still expect you can get better rates down the road but I think I am not alone in appreciation for you publishing this version now so we can mine more efficiently than other options currently available!

I have only read about half of this thread so sorry if I am repeating anything here but I did have a few observations and questions that I wanted to post.

- I have 4 MSI RX 470 4GB (strap 1500 mod, overclocked, undervolted) averaging between 40-42 Sols/s each using your miner. This is a vast improvement over the 13 I was getting using nicehash the last few days, so really appreciate the extra sols!

- I noticed that the power draw for this miner is much lower than your ETH Dual Miner.  Even just solo mining ETH my rig was using ~625W at the wall, while your ZEC miner is only using between 400-450W!  This of course increased the profit margin over ETH mining even more, which is great, but I have a question about the power consumption.  Is it just that mining this coin is inherently less power-consuming than ETH?  Or, does the much lower power draw mean that there is still a lot more headroom to work towards increasing Sols/s even more?

- Finally, after running your ZEC miner stably for about an hour this morning, I launched nicehash miner to use only its CPU ZEC mining function. Unfortunately, almost right at launch, it cut the Sols/s rate in your miner by about 25% on each GPU.  Then after about 5 minutes, it crashed my system. Then crashed again after reboot, so I haven't tried it again.  This seems a bit weird to me since I have used other CPU/memory intensive programs like Claymore Crytponote CPU to mine XMR and plotting & optimizing BurstCoin plots on HDDs and neither affected your ETH GPU miner.

Normally, I wouldn't even bother about CPU but this rig has an i7-6800k that was pulling 23 S/s, which equates to more than half of a GPU, so I hate to waste it idly.  Anyone here been able to CPU mine ZEC with NH and GPU with Claymore successfully?

Did you set your nicehash miner using -t 6 ? (6 = 6 threads)

Nope... thanks, I will give that a try and see what happens.  Out of curiosity, how exactly would you do that?  I know how to make that kind of change like in a .bat file (such as exists in Claymore's work) but I only see EXE and DLL files in the NHM directory.

i have those and works fine. I tried to mark them on paint but that fucked up the resolution (no idea why). i hope u can see them the txt and bat file.

Thanks very much! I can see it fine when zooming in. So... I checked that directory and I do not have that .bat file in it.  Did you just created that yourself and use that to launch nheqminer in a command window (meaning that you not not use the GUI)?  Or, do you create that .bat file, then launch the NHM GUI exe and that will pick up this new command?  Thanks again, I am still learning this stuff

U launch it thru the bat file. (Which u make it by urself)

Do you know of any CPU miners for ZEC that is better / faster than Nicehash's implemention on Linux?

Very nice!

[FlexiN]

I got only 240H/s with 6 Saphirre REF RX 480 8 GB, ~40 H/s per GPU with stock settings...

If someone with the same setup like me can share the settings for reach 50 h/s, i really appreciate

Thank you guys

Claymore:

Mining with nicehas get rejected shares from time to time. Only viable solution is to restart often (every hour or so). Another thing according to nicehash the miner does not use "extranonce.subscribe" which hinders performance.

Thank you for such a great miner , keep the great work

Would be great to support extranonce.subscribe, provides a more stable connection and less stale when fast switching on the NH side.

Thanks ! I found some links , but now they are all 404. But Ill search more. Thanks for the tip man, it a good idea to sqeeze a little more from 280xs

We are not switching right??

apparently it is not adversely effecting performance

   Hey Claymore
 Fix this rejects  after DEVFEE mining stop.
