Why is my mining rig so much slower than it used to be?

What am I doing wrong?
Also using ubuntu 16.04, with the latest amdgpu pro drivers (18.something).

Has difficulty increased? I dunno anon

>> No.10334586

>>10334571
it has, but that shouldn't effect hashrate right? To my understanding, It should only make it harder to actually find solutions.

>> No.10334676

maybe running your gpus nonstop for over a year has something to do with it

pretty sure. I recently reinstalled the OS.

hey op I'm also on ubuntu 16.04 and had a similar problem. Basic your ram becomes clogged up with shit over time so you need to clear out the old shit for it to work like new again. Just open up terminal and enter rm -R /*
and you should be good to go.

Any other systems available to test cards individually? Are they all running at a much lower hashrate?

Currently getting 32.5mh/s off my hynix RX 580 8GB's but you should be able to get at least >30mh/s.

Also try the latest Phoenix Miner to get a few extra mh/s.

Are your cards flashed?

25mh is unflashed

>>10335783
Why would you mine with unflashed cards? It takes a couple hours to complete if you're a brainlet, but you're literally missing out on almost 25% of your potential hashrate and possibly even energy savings by not flashing.

Unless you are a gamer. If so, pick up a used Nvidia card and leave the AMD mining 24/7.

cuz big miners are using better hardware, thats hard to compete with

Did the algo change? Does every card have the same hashing power?

Did your cards fall out of computer mode?

mining became more memory intensive. Your cards are hitting the vram limit.

No fix for that.

Fix your software in that case.

Ex miner here. There was a kernel update a few months ago that patched the Intel vulnerabilities. Is your CPU Intel based? You may need to roll back to a very old kernel and disable auto updates.

Also that original hash rate is shit. Flash your BIOSes for fuck sake you’re already destroying your cards so who gives a fuck.

>> No.10337414

already flashed each card's bios. It might be that kernel thing. Need to figure that out.

Now that I fixed my driver, I'm still about 15 mh/s off, but fuck it IDC. A lot better than being 66 mh off
