RX 570 performance reality check.

[aceinc]

I am new, and have begun mining with an RX570 8gb. Everything I read says I should get 20+ MH/s. However when I look at what NiceHash says I am getting it shows ~12 MH/s. When I look at the actual mining screen it seems to show ~8.7 MH/s.

Since I am new, I do not know whether I am comparing apples & oranges, or actually have an issue. If the latter, I would like to correct it.

Here is a screen print from the miner. It is my assumption the "Hashrate" box with 8.671 M would translate to 8.671 MH/s. Is this correct?

Is this a reasonable speed for this card?

Should I change my settings?

I am using MSI Afterburner.

One other question, when I monitor the vram usage of the GPU, it appears to only be using 34%. I would expect it to be using more. Any idea why this is the case?

Here are the current settings as reported by TechPowerUp.

Have you flashed a mining Bios or set the GPU to "compute"?

How to enable Compute Mode?

1. Download the latest GPU drivers from AMD.
2. Right-click the desktop and select "Radeon Settings". Radeon Settings main window.
3. The driver window shows up. Click the gear icon in the top right. ...
4. Head to the "Graphics" tab and scroll down to the "Advanced" section. ...
5. Select Compute Mode in the GPU workload drop-down.

I had already done all of that.

In fiddling about, I forced NiceHash to re-benchmark everything, and Kawpow ended up benchmarking badly. NiceHash is now using one of the Daggerhashimoto algo's and I am getting over 26 MH/s.

I did get a blue screen of death "Video TDR failure," however I resolved that by reducing the memory clock to 1950. I am in the process of bumping that back up and I am currently at 2100 with no ill effects.

For some reason NiceHash had Kawpow with a very high benchmark, but in production it was not producing. Now it is using NBMiner Daggerhashimoto, and doing a bit better than the Benchmark predicted.

If there are other tweaks to increase it above ~26.75 MH/s please provide them.

Here is the new NiceHash Benchmark;
