Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v10.0 (Windows/Linux)

I dont understand the bios modding. What am I to be changing on my Polaris cards I am only get roughly 20mh/s out of them on ETH.

When i load the bios following instructions, they say change timing, the timings are all kinds of crazy hex numbers.

I also get an error about my bois being too small

You cannot use GPU-Z to save the BIOS as it only saves half of modern bioses. You must use ati flash to save the bios. You are copying the memory straps from either 1500 (hynix, micron and elpida) or 1750 (samsung) and pasting it to all memory straps higher than it, such as 1650, 1700, etc up to 2000 or higher. This makes the memory run with tighter memory settings so hashes more. But it can also make the card unstable and/or crash.

How do I tell memory brand... also I am using ATI flash to pull them. They appear to already read as 2000 as thier default memory speed?

When you start GPU-Z, it reports the memory brand. Also use the following article for BIOS flashing as it tells you the correct Polaris BIOS editor version to use in order to get rid of the craxy hex numbers you're seeing:

Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.

I find 2050 is a good number for Hynix, I have had some success at 2100 but not long term stable.
Also for Hybix copy memory straps from 1500 into all the higher number ie 1625 1750 2000 etx.
I switch away from etherium for now as all my rigs use windows 7 and I am not keen on full reinstalls just cause of the half job AMD did on their block chain drivers.
So I am mining anoher Ethash coin along with LBRY
Getting 28.6 ethash and 74 LBRY on 570's Hynix
29.7 ethash and 79 LBRY on 580's Hynix
13.2 ethash and 32 LBRY on 550's Micron ( can only get to 1950-2000 stable)
