Title: ETH hashrate decrease after modded bios Post by: Fr0st975 on June 28, 2018, 02:00:45 PM Hi guys,
I tried to mod bios a RX 580 card with "One click timing patch" from Polaris Bios. Everything went well, So after modded the card and apply the Pixel clock patcher I rebooted and Start mining. As you can see on the screenshot the first hashrate was at 31.5 Mh/s but it decrease quickly when I get new jobs. https://ibb.co/ngsuZo https://ibb.co/bHxBEo Did I forget something? Before modded bios My hashrate was at 27.1 stable. I'm using Claymore 11.8 (ETH only) with beta blockchain drivers and MSI Afterburner for OC. Thanks for your help Fr0st975 Title: Re: ETH hashrate decrease after modded bios Post by: jmigdlc99 on June 28, 2018, 02:06:31 PM That is weird. By any chance did you turn on two instances of the miner?
Also looking at your screenshot it seems like you have dual mining turned on? It says DCRI is set to 12. Usually its now a better option to focus on mining ETH alone instead of trying to dual mine some other shitcoin along with it.

Thanks for your help Fr0st975 Try to Disable ULPS and make sure GPU workload on Compute mode Title: Re: ETH hashrate decrease after modded bios Post by: Fr0st975 on June 28, 2018, 03:37:08 PM That is weird.

"dcri Decred/Siacoin/Lbry/Pascal intensity, or Ethereum fine-tuning value in ETH-only ASM mode. If you did not specify "-dcri" option in ETH-only ASM mode, miner will detect best -dcri values automatically, you can also press "z" key to do it."

Thanks for your help Fr0st975 Try to Disable ULPS and make sure GPU workload on Compute mode Thank you I'll look at this later, however there is no "GPU workload" option with Blockchain drivers, I guess it's already working in compute mode Title: Re: ETH hashrate decrease after modded bios Post by: abhiseshakana on June 28, 2018, 04:51:20 PM Thank you I'll look at this later, however there is no "GPU workload" option with Blockchain drivers, I guess it's already working in compute mode sorry, didn't see that you already used blockchain driver. I had the same issue with my HIS RX 580 three months ago, and all I did is use DDU and re-install GPU driver, disable UPLS with sapphire trixx and re-flash the bios rom on silent mode, with atiflash using command prompt and use the command "atiflash -unlockrom 0" before flashing the bios rom. My issue has been resolved, but i don't know which exactly methods that solve the problem Title: Re: ETH hashrate decrease after modded bios Post by: tg88 on June 29, 2018, 12:33:16 AM Try this one:
-oldkernels (AMD cards only) specify "-oldkernels 1" to use old-style GPU kernels from v10, they can be more stable for hard OC and custom BIOSes. If not, reinstall the driver.

Your card are Samsung Memory? 4gb or 8gb?
Title: Re: ETH hashrate decrease after modded bios Post by: Mamasita22 on June 29, 2018, 04:09:17 AM Too much overclocking defo. Different modbois timings can hold different frequences. So because you use 1click, try for first round values of memory oc like 2100 or 2050 until hashrate stop decreasing. And start setting oc without adjusting powerlimit, undervolting and core clock. Your previous non-biosmodded overclock doesn't fit

Title: Re: ETH hashrate decrease after modded bios Post by: Fr0st975 on July 16, 2018, 04:21:05 PM Hello all,
Good news, my hashrate is arround 31.5 Mh/s per card (stable) after following your advices. My total Hashrate is improved by 14,5 Mh/s. ETH: GPU0 31.482 Mh/s, GPU 1 31.550 Mh/s, GPU2 31.551 Mh/s Now I need to work on the undervolting I'm at 110w per card maybe I can do better. Thanks a lot.

Fr0st975 You can undervolt using OverdriveNTool or using commands -cvddc for core voltage and -mvddc for memory voltage in Claymore miner or PhoenixMiner. Here you have good tutorial how to undervolt using OverdriveNTool https://mining.help/ (https://mining.help/) |
