Topic: Genesis Mining Presents: SGMiner-GM - now with Zawawa's GG! [Updated 17/01/2017] - page 13. (Read 140433 times)

HWinfo shows errors which were corrected as well as those that were not.
Dagger-Hashimoto is the most tolerant for these kind of errors (probably due to memory READ intensive operations) Samsung memory is the most stable in this regard...
this is how two UV 470 refs (hynix and samsung) look after 10hours of operations both doing dual ETH@28+& DCR@320+

Basically for ETH mem error is not an issue.
For XMR it's a different story, yet I'm getting rejects even when mem errors are at 0...

Nope, installed 16.11.4 this morning, and it was pretty stable for the whole day, but just a few minutes ago got 100% fan with one of my rx 480/4 nitro cards. There might be some correlation between the driver version and how often this 100% fan thing happens, but it's not just the driver. I still think it's card(s) being not 100% stable. I'm running HWiNFO now in the background, looking for "GPU memory errors". Had to actually drop my memclocks quite significantly before those errors stopped occurring. I thought I was 100% stable at 2150 memclock (1750 strap timings, Samsung chips) for most of the cards, had absolutely zero issues with other miners, but I never checked that counter in HWiNFO before. This sgminer-gm problem made me look for solutions and I've just discovered this HWiNFO thing only today, so not sure yet how it works and whether it's normal to have some errors or there shouldn't be any at all.

new 17.2.1 amd

No, that's not the issue. It's a bug with sgminer and some driver versions. I say the bug is with sgminer because claymore doesn't have issues with the fans.

I'm over 24h without fan issues now, problem solved. Use 16.11.4 or 16.11.5. Hopefully the sgminer bug can get sorted, I'd like to use the latest drivers on my gaming rig.

Best setings for RX 480 --rawintesity - w - g?

Yeah, I also thought my 2nd rig with 3x rx 480 was stable with no issues, left it for the night, and after I returned back to it today — had 0-100% fan issue with one card. That's after ~12 hours of running. The fan doesn't actually spin 100% all the time, it goes to 100% for a minute or so, and then drops to 0% (stops completely), then a minute or so later - back to 100% again.

It might be that the card is simply not stable and that's how sgminer-gm crashes? The card that was having 100% fan issues today had the "DEAD" status in sgminer. So I dropped the clocks a bit and testing it again. I'm getting higher cryptonight hashrate with this sgminer than with any other miner, so it could be just stressing the cards more than other miners and thus the clocks/voltages that are stable with other miners might not be stable with sgminer. When a card crashes - we get this 100% fan issue. That's my new working theory anyway.

Have you tried with 16.11.4/5? I'm closing in on 9 hours now without issue. Will report back after 24h.

Yes, undervolted.  Running them at 1250MHz @ 975mV before vdroop.

@Prelude
Well. I hope you solved the issue for yourself with driver reinstall.
If I recall correctly sometimes SGM XMR managed to work for a day or so without 100% ... 6+ hours for sure.
Do you run it undervolted? (Becasue I do - ETH@850mv, ZEC@910mv and XMR @910-925)

Removed 17.1.2 this morning with DDU, tried installing 16.11.4 a few times but it would crash half way through driver installation. Gave up on that, and installed 16.11.5 after another DDU cleanup. I'm going to preemptively say the issue is solved. SGMiner has been running for 7+ hours and the fans are behaving as they should. With 17.x.x they'd go max RPM within about 2 hours, then eventually the fan on one of the GPUs would actually turn its self off. That caused the GPU to overheat, reach thermal limit and turn off the rig to protect its self. For the past 2 weeks I've been trying to figure out why it would turn off, and figured the PSU was to blame. I ended up figuring out the aforementioned problem by leaving VNC connected to it on another rig.


Rig that wasn't having fan issues:

4x Reference RX480 + 2x Reference style Sapphire RX470, all 6 with modded BIOS.
Win 10 Pro X64 / 16.11.4 driver
Mining XMR with SGMiner 5.5.5-gm

Stable for weeks on end

Rig with fan issues:
4x Reference RX480 with modded BIOS.
Win 10 Pro X64 / 17.1.1 and 17.1.2 driver, both same issue
Mining XMR with SGMiner 5.5.5-gm

Would mine for 2 hours or so before 1 or more GPUs' fans went full throttle. Eventually one of the fans would turn off completely, causing over temp protection to kick in and power down rig. Claymore would work perfectly for as long as I let it, no fan issues.



 

Do you have any rigs that have no RX 470 cards in them? There might be a problem with (some?) RX 470 cards not working properly either by themselves or with RX 480 cards in the same rig. That's just an idea, of course, I'm still trying to figure out this thing myself and those "theories" of mine are a long shot  , but still might be worth checking out. My "rx 480 only" rig seems to work fine so far, I'll run it with sgminer from now on and see whether it's stable for more than just a few hours.

Well... All my rigs are fine with claymore (in fact I NEVER had 100% fan with claymore xmr) and ALL sgminer forks have this problem for me.
Some of my rigs are mixed amd generations, some are mixed rx470 & 480, and some are exclusively 470. (REFs, Nitros and a few Asuses)

At this point I have no clue as to what exactly causes this, but dual win/linux seems now as a valid option

for me its happening with all XMR miners on win, as i mentioned before, Claymore , SG , less on Wolf0 but still happens. And thos are Sapphire Nitros+ 480 , all from same series 11260-01-20G , identical.

Not necessarily a driver issue. I've had this problem (100% fan) only with this sgminer. The same rig has been mining for 2+ weeks now pretty much non-stop with Wolf's miner and not a single problem with that one. Also tried Claymore for a few days and also never had this problem with it. The only 2 theories I've got at the moment are:

1 - 100% fan happens with sgminer-gm only on mixed cards rigs. I've had this problem in a rig that has two rx 480 and one rx 470. Right now testing another rig which has only 3x rx 480 and no other cards - so far it's stable with no fan weirdness, but hasn't been running long enough yet to draw any conclusions. Then again, just a few posts earlier someone posted a screenshot of a mixed rig. But the problem could be with mixing rx 470 and rx 480 specifically within one rig. Anyone here runs them mixed with this sgminer and cryptonote?

2. Might be related to some specific cards. The rig I've had this problem on has an Asus RX 470 Strix, maybe something's about this card that sgminer-gm doesn't like. RX 480 Nitro cards seem to work fine.

its definitely amd win driver issue with RX cards, its same issues with Claymore , Wolf0 , SG while mining XMR, because of that when im in XMR mood , im using ubuntu, no issues under nix`es.

I'm speculating a bit here but this 100% fan issue seems to be a bug in amd win drivers:
It's likely a thing between CryptoNote algo implementation and drivers for RX400, as I know someone who has the same issue in Claymore's Cryptonote miner!

EDIT: which is really weird and hard to imagine

 

@Prelude
What's more interesting is why it doesn't happened on your other rig. Can you please describe the setup?
What's so special about it...Are we talking XMR? are those rx400? what OS is that? Are cards modded? how about voltage?

well... 17 is a no go for me anyways, since it enforces bios signature check...
and this:

I've got the same issue on my gaming rig running the newer 17.1.2 driver. Another rig I have is running 16.11.4 and doesn't have the fan issue. Going to try downgrading to 16.11.4 later to see if the issue is solved.

For me the problem is persistent on Win10 on several platforms: 4,5 and 6 cards on Asrock MBs (h81 btc r2.0, anniversary and B150) mostly 470 REFs, but also 480REFs.
Apparently it also happens on non-REFs (Asus) rx480 and rx470.
All cards run UV and bios modded.
Non-Polaris cards are not affected.

Any advice is appreciated.

EDIT: it can run for hours before it will jump to 100% for no apparent reason. Also various forks are affected (wolf's xmr, zawawa's GG, nicehash, etc...)
Again, it happens ONLY on CryptoNote...

P.S. ohh and I do run stable setups:

i use a 480 and 260x,they both work just fine as u can see
