Timing Bios mod for AMD cards is nothing new for increasing performance on Ethereum mining. Lately also available for RX 5700 graphic cards. Most simples is just applying 1500mhz straps down bellow, which increases performance by roughly 10-15%. But there is more to that, i was playing with the rom files. And figured out that editing Dram 12 timing also increases performance for mining ETH.

Mining is basically competition whoever can do most efficient. And you want to rigs run as efficient as you can.

So the steps are following to increase another 1-2 mh/s on top of your 1500mhz strap bios mod.

1.By default 1500mhz and down bellow DramTiming12 is set to 2850 and on some cards 2945.

You need to edit this to at least 6000 in (1550mhz,1750mhz,1800mhz,1875mhz,2000mhz). Some gpus timing starts from 1500mhz it really doesnt matter which bios you have. I tried both of these and seems like it is working just fine.

I have tested this on Asus Strix RX5700XT and also Gigabyte RX5700XT

What i have noticed your cvlt and mvdd also has to be low as possible , my cvdd was set to 760.

Im sure there is more to it and we can increase more performance by adjusting these timing. This process is very time consuming, and im sure people will find how to adjust more of this to increase mining speed.

Selling my 2060 for something better.

Posted: 04 Oct 2020 05:32 AM PDT

Hi, just started mining few days ago with my RTX 2060, and after reading a lot and measuring the hashing speed I realized that will be better to buy or another GPU or change mine. I managed to sell mine and now I have few options: 1. Buy a 5700XT an if possible another one later as they are around 300 eur and they perform well. 2. Buy couple or three 1660 super/ti. Nvidia is my preference as I'm also a password cracker and they perform well and cooler under long periods of hashing, but it's not a must. 3. Wait a few days and buy if possible a 3070. 4. Go and buy a 2080ti.

Any suggestions? I know that I'm not gonna make money from mining, just wanna compensate a bit the spending on hardware and support cryptocurrency.

Thanks for the opinion .

GPU0 not appearing

Posted: 04 Oct 2020 05:17 AM PDT

I have 5 gpus AMD rx470 4gb connected through extenders to motherboard which I used to mine until for Ethereum was enough 4gb card. Then when that was not possible any more, I set up nicehash and it started mining beam with lolminer, but gpu0 showed very small hash, like 1-2 Mh/s. GPU0 was providing sometimes up to 20% poorer performance for eth mining, but after restart of the claymore it was back up again. It had fake HDMI to RGB converter to simulate monitor.

So now I thought, I should use integrated gpu and successfully set it up in motherboard bios to have integrated gpu as main gpu, and from then on, miner is not recognizing GPU0 and is starting without it.

I did ddu to remove all drivers, trying to set up one by one gpu and doing ddu before adding new gpu back, but I always end up seeing in device manager 1 integrated gpu and other gpus except gpu0. I tried to install new AMD drivers with just gpu0 connected through extender but driver software is not being able to find any gpus to install the driver for.

I thought that maybe extender died for gpu0, I took working one from a friend, and still the same.

Now I want to fresh install windows 10 pro because this is driving me crazy. So I am asking, do you know what is going on here? When I decide to formad hdd and put fresh new windows, should I do it with integrated gpu in mb bios or with pcie gpu in mb bios? When should I connect the gpu0 and all other gpus? Whould I connect gpu0 and then install driver, or connect all gpus and then install driver?

Linux mining without AMDGPU-PRO driver

Posted: 04 Oct 2020 01:02 AM PDT

Hi guys.

I'm wondering if it's possible to mine ETH on Linux with AMD cards and without the closed source AMDGPU-PRO driver. I tried some months ago without success, but maybe something is changed.

Thanks in advance for the answers.
