Hello guys.

Im getting

GPU #1 got incorrect share. If you see this warning often, make sure you did not overclock it too much!

just one of 5, all with the same settings, the same model. Dont get why, any ideas?

the command prompt closed on me by it self... what does that mean?

I have the exact same problem and nobody seems to have any clue. I even asked Claymore and he said it could be either hardware issue or riser but I changed my riser and hardware is only 6 months old. I bought it brand new. Such a big community and no help is appalling Sad

"apalling" huh? It's very difficult for anyone to help you without A LOT more information. It could be any one of 50 different things causing the problem. Look in the last log file.

Crypto currency enthusiast and miner since 2015. Mined approx 200 ETH during 2016 and 2017 and sold it at approximately $US40 each. Then I watched it reach $1000+ each. If anyone bothers to read this stuff pay attention to this: HODL HODL HODL HODL HODL HODL

I started mining with 1 AMD 7950 and 1 R9-280X. Then I gradually built my AMD operation into 12 R9-290s. Awesome ETH hash but ridiculous power consumption and heat. Over the last year I defected to the Nvidia team. I now use GTX 1070s. They were expensive to buy (probably a bargain now) but awesome hash rate vs. power consumption. blah blah blah blah

Anyone using this miner with 290s or 390s on 15.12 drivers? I tried it with 16.9.2 but still get 31MH per card...no different than when I used Genoil's miner like a year ago. Weren't there some efficiency improvements from recoding using GCN assembler?

i found no difference on my 390 with 15.12 or 16.11.x drivers.

31 mhs @ 1100/1500 sapphire nitro

I have the same results.

I was running 290s and 390s in Windows 7 64 with 15.12 drivers using Claymore, until I tried sgminer-gm in EthOS (which is basically a custom Ubuntu Linux).

I get a higher hash-rate with sgminer-gm, using slightly less power and no fee.

I can also mine ETC,ZEC, ZCL or XMR with EthOS but obviously ETH is much more profitable right now. I have had it for many months and I switched to Windows/Claymore for a while but Windows just seems to always have problems. I switched back to Linux for stability.

All my 290s and 1 390 are at  slightly above 31mh/s except for one which has elpida RAM which is doing 30. The 290s are at core 1100 mem 1125, the 390 is at core 1120 mem 1500 and it often does 32mh/s.

If you aren't dual mining and you can use Linux I think sgminer-gm is a no-brainer.

I still haven't tried linux yet, but I think I am about to soon, because I just bought all the rest of the parts I need to build a new rig. I am going to try linux on this rig and it will be dedicated to mining/folding and the new one will be my normal day-to-day stuff/gaming rig.

Hello...
I running Eth + Decred -dcri 48 on 2 rx480 nitro+
Eth=58 mh/s
Decred=1350 mh/s
But there is one problem: too many "DCR: Share relected"
I tried to decrease -dcri to 40, then 35, 30....
And it does not help me...
Eth decreases to 55 mh/s & Decred to 750 mh/s,

Why this happens?
Eth should increase or how?

I'm on Nicehash and have the same problem, all of DCR gets rejected.

Same thing here. On one of my rigs I get the "GPU #1 got incorrect share" intermittently, it also sends correct shares from this GPU.

I've tried restoring the card to stock BIOS and running with no o/c at all, changing the riser and even switching the card out for a different one of the same model (Sapphire RX470 4GB Ref) same thing, GPU#1 gives the overclocked warning every now and again. It must be a software issue.

I did everything I could think of formatted pc, DDU driver, different versions of driver, riser change, HDD change, PCI slot change. NOTHING fixes this problem. I am using MSI rx 480 8gb. ASIC value is at 70% and above.

Question for the experienced manipulator of GPU card parameters.  I want to retain my ETH mining rate on my Sapphire rx 470 8g cards but lower the power.  I have played with the voltages on the memory and GPU and figured out where they run stable.  My question is around the GPU clock and memory clock settings.  I have the GPU set at 1150 based on some posts I read, but am I trying to get it as low as possible to reduce power?  My memory is set at 2050 and should I being trying to raise that up as much as possible?  Won't that elevate my power consumption?  I have a Mod'd bios on my cards to reduce overall power use.  But I am wanting to more fully understand the objective around changing the clock speeds.  Any insight would be appreciated.

You have probably already checked this, but make sure your miner name you gave your miner is exactly the same as what you have in your mining pool.  I had a couple that I had mistyped the name and I had the same problem until I figured it out.  Also, keep hitting the "reset pool" key until it starts mining right.  It needs to get the framework just right, and resetting it has helped me in the past.  It may take 4 or 10 times, but it will usually finally get it worked out.

Any idea on how to fix this keeps on happening on 480 cards

WATCHDOG: GPU 1 hangs in OpenCL call, exit
WATCHDOG: GPU 1 hangs in OpenCL call, exit
Restarting OK, exit... crashes and have to restart system as claymore wont exit or close

This happened when I was dual mining. I ended up having to restore the BIOS on a couple of cards back to the original. They couldn't handle the extra stress from dual mining with the modified BIOS.

Have had this happen alot.  The best fix is to simply increase the voltage on the GPU by 10 mV at a time until it stops.  If you are confident you drivers are good, and it only happens on one card out of a set, it means you are undervolted for the application.  Not all cards are equal, and I have had a number of new cards struggle with this and I have had a number of 480s with this problem, and I can get rid of the OpenCl every time with a simple increase in the power.

crazyearner do you have a reboot.bat in the Claymore folder? Inside the .bat should be:
Code:

Try to Run your cards at factory settings, that means flashing back stock BIOS, and reverting to stock clocks. If the cards are stable, theres your problem. its usually high overclocks or tooo tight timings in the BIOS mod.
If that doesent work, replace the card, then replace the riser. If neither of those work, switch around the risers on the PCIe slots to see if a particular PCIe slot is causing the failure, which could mean a faulty PCIe slot on the motherboard.
Also, change your attitude, if you whine about the community being unhelpful, its a self fulfilling prophecy. Your EXACT problem has been encountered and reported by no less than a 100 people here, and NOTHING that I or anyone else will share now has not been said before ... if only every new poster could bother to spend the time needed to look for solutions already posted.

Question for the experienced manipulator of GPU card parameters.  I want to retain my ETH mining rate on my Sapphire rx 470 8g cards but lower the power.  I have played with the voltages on the memory and GPU and figured out where they run stable.  My question is around the GPU clock and memory clock settings.  I have the GPU set at 1150 based on some posts I read, but am I trying to get it as low as possible to reduce power?  My memory is set at 2050 and should I being trying to raise that up as much as possible?  Won't that elevate my power consumption?  I have a Mod'd bios on my cards to reduce overall power use.  But I am wanting to more fully understand the objective around changing the clock speeds.  Any insight would be appreciated.

Seems like you already have found stable voltages for Core and Memory. I am assuming this was at stock clocks? I am also assuming you ahve modded your bios memory timings already. I recommend having core and memory both set at the lowest volts that you can get your memory to work on (because they will each use the higher of the two anyways).
Then you reduced core and increased memory, are those stable at the voltages you figured out earlier? Did the power draw now go up or down?
The next step would be to introduce a voltage offset for the core in a tool like watttool Because you increased Memory clocks you can not reduce the volts to it, infact you may need to increase them if higher memory clocks arent stable. Then because you lowered core, do not change the core volts but put in an offset, lets say -50mv (directly changing core volts to below memory volts will make no difference) and see if that is stable. Repeat with a lower value till you hit the lowest stable setting.
Remember, with every change in clocks the volts needed for it to be stable would also change so its a hit and try to find the perfect balance.

I recommend having core and memory at same volts (because they will each use the higher of the two anyways).

Umm....you sure about that? That is weird as fuck if it's true. Haven't used Polaris myself but any other card they are two separate voltages. For Hawaii...mem voltage above 1.05V can be dangerous and yet is probably too low for the core under load even at stock clocks. Meanwhile the core can easily do 1.25V and not harm anything.

@Swiped

I recommend you try the overclock.net forums for answers. There are lots of helpful and knowledgeable people there that will gladly supply accurate info.

http://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460/0_100
http://www.overclock.net/t/1605802/official-radeon-rx480-470-460-owners-club/0_100

If you have found the lowest stable voltages for the clocks you want and you're already running modded mem timings, then there's probably not a whole lot you can do except downclocking either the core (if you are bottlenecked by memory performance) or memory (if you are bottlenecked by the card's compute performance). If you can downclock one of those parameters without significantly lowering your hashrate then you can probably find a lower stable voltage for your new lower clocks and thus save power.

So i installed Boysies v2 rom for red devils 8gb.

But now there is no way to keep it hashing, every setting that i try results in my screen going off...

Has anybody got a solution for this? or maybe can share the setting that they are using for this rom, please.

Changed the wording above to make it clearer. What I meant was, the lowest stable clocks that you found for memory should be applied to the core as well, and to from there to undervolt the core you will need to introduce an offset as directly changing mvs below that wont work.
Also, Polaris is an efficient architecture so it uses much lower core values than Hawaai/Tahiti so stock clocks are stable at 1000mv on almost every chip, while memory if pushed to 1900+ will need the full 1000mv that it defaults to, so in most cases the higher mvs are on the memory not the core. Unfortunately the higher mvs that you key in for memory are also used by the core (ignoring what you specified it to run at) unless you introduce an offset.

Unfortunately the higher mvs that you key in for memory are also used by the core (ignoring what you specified it to run at) unless you introduce an offset.


I think you missed the point. I know Polaris is more efficient. I was just using Hawaii as an example to illustrate that there is VDDC, and there is VDDCI or AUX voltage, which are two different things. It is dangerous to set VDDCI higher than 1050mV or so, whereas the core (VDDC) can be safely higher....so to say to just set them equal because it will use the higher of the two means if he is already running at, say, 1150mV+ on the core, and then he sets his AUX voltage to 1150mV also, he can fry his card.

Also, it seems like you are saying that neither AUX nor VDDC can be set at a value lower than 1000mV. That may be the case for AUX, but I'm pretty sure it's possible to set VDDC to whatever you want in DPM 7, as long as you lower the other DPM states to a value the same or even lower. If DPM 6 is set to 1000 and you try to set DPM 7 to 950, sure, it probably won't take...but as long as you lower DPM 6, 5, etc. to 950 or less as well it should work.

EDIT: I should add that AUX/VDDCI is not actually the memory voltage, but rather the memory controller voltage, which is actually on the die itself. AFAIK the memory voltage is about 1.5V and is not configurable even with a BIOS edit. You would have to do a hard mod to change that which is a bit extreme and would require some serious knowledge. The effects of changing AUX voltage are small compared to a change in VDDC so even if you could get it working below 1000mV it wouldn't save you much power in comparison to lowering the core. I'm pretty sure the 480 hash rate is bottlenecked by its memory performance anyway, so it would be best to try and get the core voltage down because even if you had to downclock the core a bit, it shouldn't affect the hash rate too much compared to downclocking the memory.

Hi all,

Can you suggest what is best for mine eth.

siacoin, DCR, pascal  Huh

I try DCR but I finally switched on only eth, large increase in consumption and a small profit, perhaps siacoin is better?

I have 9x 470 low power bios

Hello

I will have a question about the virtual memory,

I wanted to put a 2nd hard disk of 32go on my astrock btc h81. To make a raid0. To have a 64GB hard drive.

To increase virtual memory.

But asrcok btc h81 is not compatible raid.

I can choose the hard drive for virtual memory?

Eg choose 16go from my hard drive 2.?

go to the moon !!
