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

[Seiferoth]

Hi guys!

I've come across a weird issue. I have MSI H270 PC mate MB, R270x card, Windows 10, no overclocking. And I updated MB BIOS yesterday. Since that I'm getting "ZecMiner64.exe has stopped working" right after start. Log contains only (even with debug option on):

12:02:19:594   b80   ZEC: 1 pool is specified
12:02:19:595   b80   Main ZCash pool is eu1-zcash.flypool.org:3333

I've used AMD uninstall utility and reinstalled recommended 15.12 driver - no luck.
Can someone help me to overcome this issue? Thank you.

A couple of things: Post your config so we can check if it's OK, it could be something simple. Run Claymore in a DOS box this will let you see all reported errors and can point you in the right direction to fix the problem.

I have had errors like "ZecMiner64.exe has stopped working" and the only way I could fix it was to reinstall Windows 10

I have an R9 270x 4MB card and it runs Claymore's Zcash miner OK, here is the configuration I used:

Code:

setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

@Claymore, when do you think we'll see a new version? Its been almost a year since your last update. It would also be nice to have the lower dev fee that you promised. Thanks for all of your hard work, its much appreciated.

Ok I'm ready to burn my computer.  Someone please help me.  I have a R280X that runs Cryptonite at 485h/s and according to the charts should run Equihash around 290 h/s.  I'm running claymore 12.6 on Slushpool and when the miner starts it does 275h/s.  It then begins to throttle down in steps down to 145 h/s and sometimes lower.  I recently watch it go as low as 40 h/s before climbing back up to 145 h/s.
Does anybody know why the rates are so low, and also the -i and -il commands do nothing to the hashrate.
I'm running the "blockchain" drivers but had the same problem when running AMD 15.2.
Any ideas?
Bob

Which GPU is this exactly?

Most likely your fans are dead or dying and your GPU is throttling.

Then why does it run full guns 485 h/s when mining cryptonite ?  no problem there...only problem is equihash and claymore 12.6

What Is the make and model of your 280x ?

Try using the older 15.12 drivers and set clock to 1050/1500 or so.

I have a few 7970 (280X), I run them at 950 mV, 900/1250MHz, quite stable.

I am also running a few 7970 aka 280x, @1050/1400 1110-1150mV (depends on the specific card) and making with a modded BIOS ~300+ Sol per card. If the -i setting does nothing, then something is wrong on your side, mine 280x' run stable with i 4.

I run -i 4 or 5, quite good. little incorrect shares.

Those clocks seem tame for 7950/7970/280x. The reference 7950s I have that aren't dying on me run 1475m/1225e and hash 315 s/s (according to Claymore's) stable. I was 290-300 sol/s before Adaseb hooked me up with newer bios timings ... I hadn't updated the bios since I undervolted for litecoin. I've also got them juiced up pretty good these days at 1.2v because my energy costs permit it, but they can run 305 sols right at 1.01 volt if i recall.

I don't even try to find out what errors like that mean these days. I just reflash a clean install (I use SMOS for Tahitis) and flip it back online. Fixes the "problem" 9 times out of 10, especially with Tahiti cards.

I spent way way too much time trying to get Tahitis to work right in Linux, Win 10, Win 7 and fglrx, catalyst 15.12, blockchain driver, AMD-GPU (yeah, I didn't get the memo), etc. It was a pain in the ass on every OS and always fragile if I got it working. I use SMOS because it's plug and play for my 7950s. YMMV, but I would suggest you at least make an installable image of your drive as soon as you get the drivers running in any OS.

@Claymore, when do you think we'll see a new version? Its been almost a year since your last update. It would also be nice to have the lower dev fee that you promised. Thanks for all of your hard work, its much appreciated.

The ZEC hash rate is already very fast. not much to improve.

"Already very fast" compared to what? Do you mean it is already very efficient, or is there some other technical standard you're using? I think that may sound rude, but I would really like to know.

Not much to improve? You can't be serious. How about lowering the dev fee as promised over 5 months ago? That was on November 18th 2017 to be exact. Perhaps adding support for newer AMD drivers? Also, you say that this miner is very efficient, in comparison to what? There are really only two AMD ZCash GPU miners, Claymore's and Optiminer. Claymore's does win that race by a slim margin, but neither miner has seen an update in quite sometime. There's things to improve and I'd like to see some sort of development being performed for that dev fee I'm paying. Sure I could stop paying the dev fee, but I like supporting Claymore's work. Maybe I'm just asking for to much.

Anyone know what this is?

04:03:21:942    aa9c2700        OC v5, Reset control for GPU 0, close miner right now if you want to use default control from Catalyst

I've got Tahiti cards and this keeps popping up at the beginning of my logs and not sure what this is. Anyone?

Someone has info about R9 270 (no x)?
Now i have about 170h/s in 940 core and 1400 mem. GPUs moded only in cover, because i dont know how to change timings (elpida and hynix).

As far as I know, and I have Googled hard, there is no programme (such as Polaris Bios Editor) to modify the memory straps on an R9 270 ('x' or 'no x').
I did modify the memory timings an R9 270x using a hex editor but it made no noticable difference to the hashrate.

If you want to try and hex edit your GPU BIOS this here is the link on how to do it..

Really wish the miner would be updated to work with Nvidia cards, EWBF and DSTM are nice but this miner on my AMD cards seems to perform more consistently.

[bluudz]

Hello. I'm trying to run the miner to mine ZenCash on Linux Mint 18.3. When I start the miner I'm getting ''No AMD OPENCLGPUs found, exit''. Do I miss some parameter in the command to detect the card or missing the correct driver? I think I only have the stock drivers which came with Linux in default. GPU I'm using is Radeon R9 380. Also what should be the expected hashrate if anyone knows?

Thank you for any help

[pr3fix]

I believe this is not a priority for him. As far as I can see, there was not update for a long time. Ethereum miner is important to him, he is constantly updated.

Yes, it would be really nice after so long to release a new miner, if possible without dev fee or reduced. I don't think it can get any faster, maybe very little, or if he write a completely new code - algorithm.

In any case, Claymore is a good coder and miner.

I second that, Claymore is a great coder and miner. This miner is definitely not a priority for him and he's made that known. That being said, its been a very long time since an update and he promised that reduced dev fee almost 6 months ago now. I wouldn't mind paying the full dev fee as it stands today if he would make more consistent updates, even if that was just to support newer AMD drivers. I'd love it if he rewrote the miner even more efficiently, but I think that's a long-shot at this point. @Claymore, can you give us any idea when we might see some love my friend? Its been a long time since we've heard from you. Thanks again for your hard work!

vegas hashrates ??

I got about 420-440 sols per card (Vega 56) and about 680W (3 cards). Tried some solo mining BTCP for 3 days but no results 

[ivomm]

It's too bad zcash team is corrupted and don't want to fork to make Zcash asic resistant.  New asic miners are 10 times more efficient than a gpu rig with the same price. They are already accesible by some and soon will be available for sales.

The developer Zooko is a paid by Ver/Wu shill. He deleted Peter Todd's Asic resistance code. Peter Todd is a famous Bitcoin Core developer, and as we know Ver is in open war with them. We all know that the money in zcahs team came exclusively by Ver, so no doubt what is going on.


Here are links of Todd's twits:

If the ZEC is not changed with the PoW to be more ASIC resistant, it will be used less in the futrue.
