That would be an awesome feature and maybe extend the life of the z9 mini for a bit. I've been eagerly awaiting another release, I hope to see one in the future.

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!

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.

@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.

I'm having some trouble with Claymore ZCash miner on my six Sapphire Nitro+ RX570 8GB Rig, which is running on Hive OS. I continue to receive the message GPU0 returned incorrect data! I am receiving the same message periodically for all the GPUs on this rig. I have tried lowering my intensity to 1 and I am running the cards at stock settings on the original bios. I am running on amdgpu-pro 17.40-492261 driver. I have also already tried replacing all of my riser cards twice. Can anyone offer anymore suggestions of things to try? I don't seem to have this issue when using Optiminer, so I'm not sure what's going on. Thanks for the help!

That’s what I’m saying! Nothing like promising to lower dev fee in your next release after folks complained and then making them wait several months for you to deliver on that promise. Might I also add while happily taking the same amount of crypto from them this entire time. What’s his incentive to give us this update? I’ve posted several times here asking for updates or about potential changes in the next release and I can’t get a reply. I’m beginning to lose hope that it’s gonna happen. He completed the Dual Miner and XMR changes he said had to be done several weeks ago now, but we have not received any updates here.

It’s card dependent, which was the conclusion I came too. You can’t say either way, it truly depends on the card. With the R9 380X  it’s not true that increasing core clock increases hashrate, but it may very well be true for other cards depending on how they are built and/or configured. My initial thought was that the RAM clock was the primary driver for hashrate, but as you and others have indicated, this is not always the case.

Yeah MSI Afterburner isn't bad, but it depends on what AMD drivers your using and what graphics card. It doesn't always work right and I find that using Wattman actually is a lot easier and effective.

I was really hoping I could get 280h/s out of my 380X's using the settings you shared for your 280x, however, they lower my hash rate to about 209h/s per card. For me, setting my GPU clock to 900mhz and my RAM clock to 1625mhz produces the best result on the 380x in terms of performance/efficiency at 220h/s. Sure I can overclock my GPU to bring them up to 228h/s if I increase the ram to 1640mhz and uses an 1100mhz gpu clock as you suggested, but it uses so much more power I'm worse off. Just increasing the GPU to 1100 from 900 does nothing for me. I truly think this maybe a card dependent question.

@Claymore, my offer still stands, how much ZEC will it take to get you to make some improvements for the R9 380X (Tonga) in your next release?

That doesn't make a whole lot of sense to me given that Equihash is a memory hard algorithm. Its possible that increasing the gpu clock might help some, but that's not what's doing the majority of the processing so it should not produce a significant change in hashrate. I'm not sure what your doing, perhaps this depends on the type of card your dealing with, however, the above is my experience with the R9 380X.

Typically with Equihash, overclocking the ram will produce an increased hashrate.

As others have stated, the RX550 is not very good graphics card for mining. However, it should be capable of much more than 28 h/s. My guess is that Claymore did not code in support for the "Lexa" chip in version 12.6. You may have to try another miner if he doesn't plan to add support for it in his future releases. Also, just to make sure nothing is wrong on your end, please verify that you have the correct drivers installed. You can refer to the first post of this thread for a list of the best drivers to use.

I agree, the 380X performs much better with Ethereum, I’m getting between 140-150mhs on my six 380X rig. This is also what makes me think Claymore maybe able to tweak it a little more for ZEC, hence why I’m willing to compensate him for his time. I also agree with patience, if your not mining right now, it’s not the time to try and buy hardware and going with inferior hardware does mean no resale value.

While I don’t disagree with you that the 380X and 560 are not the newest or greatest cards for ZEC mining, you have to remember not everyone has the resources to go out and buy 580’s, 1080’s (if you can find them) or the next greatest card to be released. Not everyone has a warehouse full of miners. As I say all the time, don’t forget the budget hobbyist miner, that’s how all this crypto currency stuff got started. One guy with an idea and zero resources. My point, the little guys are the ones who innovate, even on old or junk hardware. These rich guys are just after profits, they don’t care about the technology or privacy. I’m also offering to send Claymore a ZEC donation if there’s anything he can do for the 380X, while others are here whining about his fee and actively searching for ways to thwart it.

Lame, I understand the frustration with the 2% fee, but no one should be trying to beat it. I’m sure Claymore has put hundreds of hours into developing this miner, it’s only fair that he receives compensation for his hard work. This is likely just a creative way to get greedy people and newbs to download a virus as someone else already mentioned. That being said, I have a couple questions:

@Claymore, how’s that new version coming along? It’s been about 5 weeks since your last post and I see that new versions of the XMR and Dual Miner have already been released.

@Claymore how much ZEC would be required to bribe you into making some improvements for Tonga chips, specifically the R9 380x in this release? Being a budget miner with a six R9 380x rig I need to squeeze as many hashes as I can out of it as it consumes a very power hungry 1000 watts. Is there anyway to increase the hashrate on these to be greater than 225 h/s?

I’ve been running 18.1.1 for about a day now with Claymore 12.6 and I have not seen any differences in speed or stability. The only major thing I’ve noticed is that my cpu temps and fans speeds are displaying  again. They did not work right with the 17.2 drivers.

There's nothing wrong with AMD cards. I have a mining rig with 6 Radeon R9 380X 4GB and it runs just fine at 940 watts. nVidia cards such as the 1060 are definitely more power efficient, but they are also newer cards and cost more money to get started with. Chances are the problem was with drivers, I've always found AMDs drivers to be difficult to work and god help you if you try to run under Ubuntu. I was never able to get my rig running correctly in Linux. I also used windows 10 professional without any issues, nice and stable on Claymore 12.6 with the Crimson ReLive Edition Beta Driver Version 17.30.1029.

@Claymore how’s the new version coming along? What kinds of improvements and changes should we expect with the next release? When do you think the next version will be ready for release? Thanks for all your hard work it’s very much appreciated!

@halker2010 - Just wondering how are you getting 280 - 340 Sol/s with the R9 380X? What driver are you using? What are your overclocking settings and what custom BIOS if any are you running? I have three of these cards and I have only been able to get 235 sol/s from each by overclocking. If your using a custom BIOS can you please email it to me? It would be very much appreciated. I haven’t been able to find one for these cards and I would love an additional 45 to 105 sol/s from each of these. Thanks in advanced for the help.

Thanks Claymore! Any improvements for Tonga cards are always appreciated. On my 380X 4GB OCed at 1080/1550 I'm able to consistently keep 210 h/s using -i 6 and its been stable for several hours now. Based upon your comment, it sounds like some of us need to start considering upgrading to new hardware or mining another cryptocurrency if we'd like to keep using Tonga cards. If I decide to building another mining rig for zcash, what cards do you find the best? Is there a particular one you'd recommend?
