I just bought a new mining rig and i have some problems.
GPU 0 is running at a lower hashrate then the other 5.
I would like to overclock the cards, i'm getting 270 h/s, i don't know if its possible to get 300 out of them?
Do i need to change the BIOS or just my config?
I'm using Catalyst 16.2 as recommend by claymore zcash miner, windows 10.
Any help is appreciated.
Thanks

Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

The Claymore readme hasn't been updated in a LONG time. You should use the AMD blockchain drivers. Those are the drivers optimized for Polaris cards. Since AMD changed the API starting with the Relive drivers v17.7.2, you also need to use Afterburner v4.4.0 beta 16 or higher. I have four Powercolor Red Dragon RX 570 4GB cards and with the Claymore ZEC miner I get ~318 H/s with a 1325 MHz Core, 1975 MHz Memory overclock, -96 mV undervolt and -15% Power limit in Afterburner. https://www.guru3d.com/files-details/msi-afterburner-beta-download.html |

Okay awesome. Will try it out.
Did you mod your BIOS. Or is this only for ETH mining done ?

For ZEC mining it shouldn't matter much if the Bios is modded or not. My Red Dragon Bios is modded with the PBE v1.62 'one click timing patch' from jaschaknack. https://github.com/jaschaknack/PolarisBiosEditor |

Ow okay, do it need to run the patch, i saw a video saying it won't work without, on the 570's.
Do i need to mod every card?

Okay, thank you i'll try it out and see what happens with my hashrate.

use commandline atiflash, but you can't flash all at once. the help is good enough to find all that's needed yourself. |

But don't have an increase in hashrate. How come in the video the guy is lowering his ccore clock, and you are highering it. When i use 1325mhz, my pc screen blacks out, when i use 1300 i'm getting a lower hashrate. How do i unlock my voltage core, on Afterburner Which intensity are u using ? So far i'm not getting over 275 h/s. And GPU 0 is still hashing at a lower rate then other cards... |

For mining Zcash the amount of Ram is not important as long as you have at least 4GB of RAM DDR3, but 8 GB is the recommended amount.
What memory has this GPU-0 of yours ? Check it with GPU-Z program, if it is Hynix it doesn't care if you overclock it or not through Afterburner it will not show you higher hashrate. That's a known problem with Hynix memory.
If it doesn't recognize, your 6th GPU, you can try DDU, direct display driver uninstaller, then restart and reinstall the drivers. It should recognize it now. (it may not recognize all cards directly, some may show, as VGA Basic Adapters, click on them and Update driver until all are recognized)
Also tell me what motherboard do you have, some motherboards do not support overclocking all the cards.

OK, so you have the best motherboard available to date for mining in my opinion and I have seen this board supports overclocking.
To check for 6th card, do the DDU thing I told you earlier.
After that check with GPU-Z each card what kind of memory have, if the one offering a lower hashrate have a Hynix memory then there is not much you can do through Afterburner utility, memory and clock will go up but result will be same hashrate from such card.
Keep in mind that you need to have all Windows updates which are a lot since you have done a fresh install. They impact a lot the performance of Windows 10 especially in mining.
Also last thing maybe the riser, try replacing the riser of the last GPU, the one who gives you lower hashrate but highly unlikely if this card happens to have Hynix memory.

I solved the problem. I changes the virtual memory from 16 to 24 GB's.
Now all my cards run @ around ~ 270-280 h/s.
I would like to get 300 out of them.
But i don't get any higher rates out of them with highering/lowering cclock. Highering memoryclock.
Etc...
Do i need to change settings in BIOS. Or do something else?
