FUCK XUBUNTU!

That is all....

Well if I spend another day or two beating my head against a wall with it I'm gonna try Manjaro again.

naw I know you can't really talk about Vega. I take it you sold all the optimizations to some farm with the stipulation that you can't tell anyone else about it? Man I bet they are getting like 70Mh per card.

Anyway what I did was this:


Then it would boot with ROCm kernel 4.11, but wouldn't hash. Said something about needing DRM 3.x.x and I had v2.5. Thought that was because the 270 was still on the radeon driver (even though I was only trying to mine on the 570 which was using the amdgpu driver according to lspci -v). That's when I ended up breaking the install messing with it (I think blacklisting the radeon driver broke it). It would still run with the default 4.10 kernel and it would hash, but without the dag fix (only 24 MH/s when it should have been getting 29+).

Anyhow I'll try it again. I may have fucked myself trying to install the amdgpu-pro driver so maybe I'll skip that part this time. Thanks for the infos!

But, like...I just wanna get hashing on Polaris with the dag fix. Nothing fancy. Even if it's 1MH/s below Windows without completely breaking the install I would be happy.

Well lay some skills on me bro! 

Well I don't want to pay for it either.  Isn't EthOS like $30? I'm sure I could find a torrent or something but then I probably wouldn't trust it. What do you recommend?

A large part of the reason for doing this though is just to learn linux, so I kinda wanna stick to a normal distro (either Manjaro, Debian, or Xubuntu) and also use it for gaming/browsing/email/video, etc.

Ahh good to know. That makes it easier to compare then.

I remembered I asked you earlier about how to set up Linux and you said any use any recent kernel and amdgpu drivers and not amdgpu-pro, but you need the OpenCL runtime. Is that is still true now that there is a DAG fix? Is 4.10 a recent enough kernel? How do you get the OpenCL runtime? I read a comment somewhere that you are supposed to install the amdgpu-pro drivers with the '--compute' flag. Is that correct?

I really wanna get Linux setup and running so I can move all my rigs over, but unless I can get it hashing on par with Windows it's not worth it. I managed to get it running with amdgpu drivers but I was getting pre-DAG-fix hash rates, and ended up breaking my install trying to mess with it. I think that had something to do with blacklisting the radeon driver though (the primary GPU in the system is an R9 270).

Also are there any publicly available tools to monitor voltage/clocks/temps/fanspeeds, etc? lmsensors doesn't find anything and conky and grkrellm don't seem to be able to see voltages.

Actually he and greatauror were talking about a specific samsung IC. Although he is no doubt also using a custom kernel whereas everyone else is posting their hashrate reported by claymore in win, so his increases don't necessarily all come from optimized timings.

Like I say I have a few Elpidas and none of mine will even do more than 2020. The lowest 2 only do 1960/1970.

Try the ubermix straps. 1900 seems awfully low for samsung.

Out of 9 500-series cards, 5 of mine have that. You could say I went for cheap ones, but I bought them all no earlier than late June, so none of them were that cheap

When you say beta blockchain drivers do you mean amdgpu-pro 17.40? I'm trying to figure out which kernel/firmware combo you need to run on linux with the dag fix but I keep breaking my install lol :p

Some of the posters are obvious trolls. Anyone else I'm not sure why they're surprised. It seemed pretty likely by late June that the coin was going to have to retest at least the 30k level if not the 20k level. Almost all the alts are having a hard time right now, but after the bitcoin 2mb fork I'm sure we'll see a recovery. Look at this as a buying opportunity.

The diff depends on the pool, and even the socket. Even then if the dev fee uses the same pool and socket, but it's a variable difficulty socket, then the difficulty can be set lower when it makes the new connection and probably won't even settle in to your normal difficulty by the time the dev fee mining is over.

That's why you should look at the amount of time spent dev fee mining, rather than purely the number of shares. Number of shares doesn't mean anything if you don't know the difficulty of each.

It's probably connecting do a different pool with lower difficulty shares for the dev fee. Check your logs.

That's actually not great. Power usage could be much lower. For example I have a 4-card rig that pulls ~580W from the wall (with a bronze PSU so would prob be more like 550W with a gold). The rig pulls 80W @ idle so each card pulls about 125W under load. Stable for over 530 hours w/ over 29MH/s per card. If this were a 6-card rig it should only be pulling between 780W (gold PSU) to 830W (bronze PSU).

EDIT: Ahh nvm...just noticed he is dual mining DCR. Different story.

It's somewhat hard times for miners right now.

Since the boom that happened over the summer there are a lot more GPUs driving up the difficulty lately. Add to that a bit of a downtrend in the alt market because of bitcoin forks, and you have the current situation.

Still, I don't think it's as bad as it was in 2015. The way to get profit is to hodl and look for undervalued projects. After the fork to 2MB blocks alts will probably recover.

Sepaking of....how is that beta test going?

Can't say I'm familiar with that. My rigs run for weeks until I reboot them or unless they crashed because of something I screwed up, like having voltage too low/clocks too high, or not having the power cables connected properly, etc.

This is why you throw away those shitty SATA > Molex connectors and use the Molex cables that come with the PSU. It's not the wire gauge, it's the extra/crappy connectors. In open air you should be able to run 150W or more through the 12V wires even with 18 gauge. That should be enough to power 3 risers off of one Molex chain, and definitely safe for powering 2.

Alternatively there are newer risers that just take SATA. Haven't tried them but they'd probably work OK since, again, you don't need to use any janky adapters.

EDIT: Ok technical specs put it at 132W (11A * 12V) for 18 gauge...but still most cards shouldn't draw more than 45W through the slot (though technically they can draw up to 75W). Also there is some margin built into the ratings, so in open air with decent ambients and air flow, 3 cards per chain should be fine; and again, 2 is definitely OK (as long as you are not adding extra/faulty connection points into the circuit with crappy adapters, because that's where most of the resistance will be and can cause arcing).

That said, I remember reading about early 480 (and maybe 470?) cards drawing stupid amounts of power through the slot...so I would be careful with those.
