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

[Rutdam]

my hashrate has dropped from 165h/s to 150h/s

i switched from minergate pool to flypool
i was getting 165h/s on minergate pool, but when i switched to flypool, i started having 150h/s
i switched back to minergate pool and still same 150h/s

what could  be the problem?

If you restart the computer, is that still 150H/s?

yes... same.

You may need to lower your overclock on that particular GPU and/or raise the voltage (if you undervolted it) to fix the invalid shares issue. Try reverting it to stock settings for testing first of all.

All gpu´s are in stock clocks and not undervolted.

With win7 everything was working 100%

Hmm, if you're at all stock settings then you're using ~250 watt per GPU? You might not have sufficient power if that's the case since 7 x 250 is 1750 watts just for GPUs...

Hey, good point, havent even think about that, have to learn how to undervolt those

You could use MSI Afterburner to reduce the mv on the core clock as well as reducing the power limit. Unfortunately you can't undervolt the memory with that program so I am using AMD's Wattman for all my tweaking right now, but that doesn't work with R9 280 series as far as I know. Perhaps wattool would work, but I'm not sure. Afterburner will help allot even without being able to undervolt the memory.

Hi, Thanks for this, Measured the power usage today and it was 1650w, So could it still be power problem? Rejected shares are coming very suddenly, 5h mining and 0 rejected but sometimes after 30min mining there can be 2-3 of them, Mining on Claymore´s dual miner there is no that problem, rock solid after 24h mining

Something else worth of try?

Hi, I got 5 RX570 but Claymore one recognizes 4.
The AMD Radeon control centers also shows 5.
I use this driver: non-whql-win7-64bit-radeon-software-crimson-relive-17.5.1-may4.exe

Any hints?


Sorry, was my fault, it 570... can't claymore handle the 570's?

Check Device Manager in Windows. If the 5th card is disabled, you need to mod the drivers to use more than 4 cards on Windows 7.

Looks like it's an issue with incompatible RX 5xx drivers with more than 4 cards. You need to patch them with older drivers:

I think the driver reset, so i had to increase the clock and got back 165

my fear is that, i don't want my GPU to fry, as i have increase the clocking through the driver to:
temperature: 68c
Fan speed:    70

my hashes increased from 150 - 168
is this normal? or my card at high risk of frying?

At 68 degree, your gpu will be fine.

Guys my SAPPHIRE 280x 3GB is only using 5 intensity and mining at 290H/s, is this normal? shouldn't it be running at 6 intensity? i tried forcing it but says not enough memory
anyone else have the same gpu? do u guys get the same thing?

-i 5 is max for 280x, but I have modified timings on my sapphire with elpida memory at it doing 330h/s now, but it's sometime unstable because of huge undervolte. But since Claymore v12.4 have great whatchdog, I don't care about unstable work of cards, miner just restart cards in case of crash.
If u don't care about electricity, I think sapphire 280x could have even better results after card acceleration.

Mine is Elpida memory too, electricity is cheap where i live. can you explain how you did all of that or give a link if possible please?

What is your percentage of rejected shares on average? I get approximately 1 in 200, or 0.5% with Rx 470s. I consider that to be extremely stable myself.

Something that could cause rejected shares, esp. ones that seem to be inconsistently grouped together is a flaky internet connection, wifi in particular.

You need to reduce the intensity to 6 or lower.

Already tried that, I changed it to 4. For some reason when I start the miner it still says the intensity is 6. Guess I'll really try putting it into a different slot like br2459 said and see what happens. Thanks guys!

Change the PCIE to generation 1 in the motherboard BIOS. Reinstall the driver 15.12.

For anyone having this problem this really solved it! Went to my "rig" today and did what RastMan said to do, worked like a charm. Not only can I lower my intensity bellow 6 now. I can also run the latest miner, which gave me a boost of about 40H/s. Thanks for the help!

You can search for the 280x mod in the forum.

Hi all

Can anyone help me with 480 nitro+. After I change my bios on mod and restart my PC, my rig dosen't work?
Do I have to reinstall my drivers or something?

I am assuming you are in Windows 10 so yes the windows need to "see" your new GPU's bios mod
They will start going black screen and appearing in a loop trying to cope with the change.
Do a reboot after that and if the cards are not recognized as they should you have to do a DDU and reinstall the drivers

I give it a 70% chance that you will need to reinstall drivers 

I did DDU an reinstalled my drivers and  still have the same problem. Driver menager shows me an issue with this card

Since you are using a custom BIOS the driver you use will either have to be older than 16.12.1 (AMD started BIOS signature checks in this version and newer). If you are windows 10 there is a workaround to doing this using the newer drivers. I use 16.12.1 for my ETH rig since my R9 380 runs better on that driver than older ones. You can find the guide here: https://www.techpowerup.com/228536/amd-bios-signature-check-re-enabled-with-relive-locks-out-polaris-bios-modders.

You will need to have physical access to your rig to do this it requires you to boot into "Safe Mode"

Also I would like to know the results of your BIOS mod since I have 2 of those cards running ZEC currently unmodified.

Never did such thing and don't want to damage my rig. Would I have the same problem, if I had windows 7?

Is this "acceptable"?

[joe50]

i think no reward for rejected shares and i think its depends on the pool.
some pool has high rejected shares while some just little or no rejected but main cause is bad network i guess.

[tixi54]

My hashrate drops quite a bit after an hour using 12.4 and windows 10 64bit. When I switch back to version 12.3, the hashrate is slightly lower than 12.4, but stays constant. Any solutions for 12.4 miner?
