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

[Acguy]

Another great update thanks!

[KrokoTill]

Thanks claymore...
320 sols on 290x stock and
290 sols on 290 stock 

Try 1100 core and 1125 mem on your 290s.. I'm getting 320ish each

290 - 1050/1250 - 320
280 - 1000/1500 - 195

How did you get it?
I have a xfx r9 290 = 295 h / s

With bios mod

[adaseb]

Reference r9 290 stilt bios @ 1000/1450 = 305 H/s

I can probably run this at 1150/1450 and get 330-340H/S however wife is already complaining about the noise.


Anyone got any Pitcairn improvements? Too lazy to test. 280x/470 seem to be the same

What does "GPU1 hangs in OpenCL call" mean?

What does "GPU1 hangs in OpenCL call" mean?

Possibly faulty PCI riser, Try replacing GPU1's riser and it might go away.

Check your overclocking. Does it happen on stock rom?

[pilotbtc1]

you are the best Claymore! no acceleration and no firmware provide 5 -1 576 h / a. 390X 290x 390 390 390

Everything is stock, I will try with a different riser.  What is actually going wrong though?  Not enough power or signals getting crossed or what?

Try to swap your card on a other slot

Same problems i have but only with one, exactly one, card. Miner named it GPU#3. Changed a couple risers and whatever but always the same card.
So, card needs more vGPU power. Try to rise vGPU and PowerLimit only for that card. That is the settings helped me.
Don't know the resons but that card have good ASIC around 85%...
I have 10x msi rx 470 8GB cards (~2270sol/s) and plane to change them for gtx 1060 3GB versions (for ZCash). Cooler and less power hungry with good statistics for ZCash mining...
Enjoy

I picked the riser up and put it in another slot and it has been running for about 15 minutes now at full speed without any issues.  Why on earth would the the specific slot make a difference?

EDIT: as soon as I said that I got, "GPU #0 returned incorrect data! d07f5ff9" and it is now running at 0 hashes per second and is getting the same GPU hangs message. Blah
At least when it restarted itself this time the GPU actually came back on as mining.

THANKS Claymore!

9.3 is about %1 slower on RX 480 and RX 470

BUT it is much more stable!

No hangouts

It works almost 14-15 hours without problem.

9.2 and 9.1 was not stable for me.

Hmm, it seems 390X can reach 400H/s though it requires some additional efforts, Polaris cards can get some speedup too.

 Is it possible to improve Fiji hasrate as well? They do an avarage 360 now. Thank you very much

Honestly im thinking we have got all what we need for rx series. Just bkz of 256 bit band. Any empruvement is only cards with 386 bit ram band.

[QuintLeo]

Hi can anyone help me i have a psu on 700w and 2x rx 470 xfx 4gig & 1x rx 480 nitro 8gig and i dosen't get it to work when i start the miner my computer hangs and i have to restart it a fast easy guide to undervolt cards or something pls!

 Check the PS +12VDC rails - if it's not a single-rail design you might be overloading one of the rails.
 If it IS a single-rail design it still might be marginal for the +12VDC draw.

 Not all "700w" power supplies are built equally.

performance of 390x=rx480. But rx480:240H/s, 390x:400H/s. why? people understand?

The R9 390 has more memory bandwidth and more computing cores.

I agree with that. The R9 390 has 512 memory bit, so it is faster.
