Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[TheMiningDwarf]

I don't know if it works with MOD bios. I don't mess around with that - maybe someone else knows. It works just fine with RX480's. Here's a picture of Claymore 11.1 linux on Ubuntu 16.04 LTS using 6 RX480's:
>img clipped<

did you ever tried Optiminer on Ubuntu 16.04? People get 280-290 H/s on RX480 AFTER fees, not before (what you are posting).
Small difference, but still.

I get 305 per RX480 with optiminer
I have 18 RX480, do the maths, its a huge difference.

ok, so I can give optiminer a try. It says on the github page to use linux driver 16.40.5. I can't find that. I can find 16.40, and 16.50, but not 16.40.5. What's the linux driver version to use?

linux 16.04
driver i used the lastest one on their site
same for apk

Can you guys share in which pool how much zec you get for what speed?

I get 0.33 zec/day in dwarfpool with 6200 s/s. Which I think is very low.

With the same speed in coinmine.pl I get 0.52 zec/day.

0.53 - 0.61 flypool with 6800

Hi,
I need your help.
I have 2x 280X cards and I was using the v8.0 miner (because that's what the pool I'm using directed me at).
Everything was working fine, until I upgraded to the newest amd driver 2 weeks ago. After that the miner would get stuck in a loop at random times, telling me that there was an issue with the gpu.
I've downloaded v11.1 and tried that, but the problem got worse. The miner will get stuck immediately after startup.
I downgraded my driver to 15.12 hoping that would fix the problem. It works more or less now. I can only use my primary card, in the upper most pci-e slot.
For diagnostics I took that one out and started the miner with the other card in the second slot. I immediately got an error message, telling me that no opencl gpu was found.
Is there a way to get my second card running again? (It will neither work with the v8.0 version that was just running fine before the driver update)

Do you think these spikes can be the reason why my rig freezes? I will describe my problem a little.

I have a 7970, a 280x and two fury nitros. During the last couple of weeks I have been trying to run my system stable with no luck. Freezes can happen at any time after starting to mine. Sometimes minutes, sometimes hours.

Rig specs: Asrock 970 extreme4. Sempron 145. 8GB ram. EVGA 1300 G2. Sapphire 7970 ghz edition, sapphire 280x vapor-x, 3x sapphire fury nitro OC. Tahiti cards undervolted on bios, fiji cards on msi afterburner. No OC on furys. Win 10. 12.6.3. CM 11.1.

First I changed all risers to v6 ones.

Next I upgraded the processor to athlon x2 because I noticed that I was getting less hashes when MSI afterburner was on and I thought the system would be more stable.

After a couple of days more I changed the mobo to asrock h81 pro btc with celeron 1840.

Still no luck.

I thought that the power was insufficient so I added a corsair rx1000 linked with an add2psu device.

No luck, freezes persist.

Changed EVGA to corsair hx1200i. This psu is powering mobo, raisers and tahiti cards.

Nothing changed.

I stopped undervolting. Still same freezes.

One fury died the day before yesterday. No fans, not detected in win 10, not detected on ubuntu, mobo not booting when the card is alone.

I changed risers again to the furys.

I used separate cables for each riser.

I powered the offending fury card with one cable for each connector. Still the same.

I tried catalyst 15.12. Same effect.

Sometimes I see 511 degrees in the fury card on CM log prior to freeze, sometimes it just stops hashing without any error and the watchdog doesn't restart the miner, sometimes all 4 cards go to 0.000 hashing without any error, sometimes after gpu reported incorrect temperature 511°C.

I'm already out of ideas.

Any hint, anyone?

Edit: typo

I have the exact same issue as you describe.

2 x 7990 & 2 x 7950
Enermax 1500w Maxrevo
Celeron cpu
Asrock Z97 Extreme 4

The worst part is it cuts out randomly, sometimes it can be 10mins and others 12hours.

When I have seen the cut outs it happens exactly the same as if the PSU cuts from being over loaded.

I had also observed the power spikes in GPUZ and it normally happens when a share is accepted.

I had guessed that it might cut out, say, in the rare instance that 5 or 6+ shares are found simultaneously which causes a huge spike cutting the PSU which would explain why it cuts after an arbitrary amount of time.

I have no watt meter, however, I assume my cards are running the PSU near to the limit but but I can't check.

I have never really got to the bottom of the problem, however, it seems running Afterburner -20 power limit core at 1050mv leaves my system stable indefinitely.

i have this problem before... first i found 1 sata power to powering the riser is burning on psu socket... and i think its happen because i use 1 sata wire cable to power 3 rx 480 riser, So i make a change to 1 sata cable to power 2 riser and the problem solved... so check your sata cable power to riser and check every riser if have sign of burn socket

[QuintLeo]

guys can we use both of nvidia and amd cards in one rig?
for example 1 r9 390x and 3 gtx 1070

 You can - it tends to be a bit less stable than a non-mixed rig though.

 I've got a couple rigs that ran a pair of 1070 with something AMD (usually a HD7750 or HD7850) for a while, one of them is still set up that way.

 You'll have to run something else on the 1070s though - Nicehash or whatever - since Claymore's ZEC miner is AMD specific.

@malandante

looks like you swapped everything out but the actual cards.. and maybe the memory on the mobos? run memtest86+ for a few hours. use the bootable iso on a cd or usb stick, no OS.

set the pcie gen to 2 or 1 in the mobo bios, that seems to keep cards on risers happier.

no bios mods on the videocards? basically everything is stock?

Yes everything stock except undervolt on tahiti cards. Anyway I tried with and without either of them (I always need to have a tahiti b/c my monitor is an old vga one). The ram sticks and the second mobo are brand new so I didn't think about memtesting. I'll check about gen 2 or 1 in mobo bios. Thanks!

I thought these spikes pretty much disappeared by version 10.x-11? Can someone confirm?

I'm seeing these spikes on my furys reaching up to 318w according to hwinfo64

Question for all...

I have an issue I've never had before.  I have 12 rigs running, half msi 480 x 6cards and half R9 Furys x 5cards.   Two of my Fury rigs have some type of oily liquid leaking.  It's coming from one of the cards on each rig. Ever since I switched to 11.1 and started messing with the intensity did I notice the leaking.  I pulled the cards and am going to RMA them, was just wondering if anyone else has had this happen to them.  The temps of the cards aren't even close to the max rated so I'm not sure what the cause is.  The ambient temp in the room has been the same since I started mining 2ish months ago, fans blowing on all rigs.  

[KrokoTill]

Yes I'm working on new version with speedup for all cards. Need a few more days though.

Can you estimate how much will power usage increase?

I thought one cable is insufficient for one card with power spikes. For some reason it could be that the psu is unable to deliver the necessary power if the 12v line is weak. I mean, it could be that from the six or eight pcie connectors on the psu, some can deliver less current?

When I wrote my post, I had started to try with two cables on one card and I thought it crashed because I was at work and the pool made me thought the miner crashed. But my wife checked it and it was still running. I'll post if that is the solution.

If it still fails, I'll boot on linux and test more.

I had a similar issue with a bad batch of MSI 280x fans a few years back.

Apparently the fan hub/bearing includes a gel lubricant, which when run at high speed over an extended span can become liquefied and be forced out of the fans.
I had several rigs with every card partially coated in a very thin layer of the stuff, one even had a slow-motion drip suspended from the bottom edge of the PCB.
Thankfully I'm told the gel is non-conductive, and I only noticed the issues when the fans began to seize up.

MSI should RMA them no sweat, there's just no guarantee they'll send more Furys. My most recent RMA of R9 290s was replaced with 6GB GTX 1060s

could be flux.  I wouldnt worry too much if it hashes correctly.  Send an email to the manufacturer and ask.  Or as the above poster said, gel.

Hey, its probably coming form the cooling fan bearing. A couple of years ago I had a couple of sapphire reference 7950's. they were on dual slots over under in a tower. The top one (which always runs hottest) dripped that smudgy fluid (grease or flux) out and down onto the 2nd card below it and shorted out the pcb circuit board due to where it was leaking out from above. After that card died, I looked at the one above and noticed a thin film of that horrid grease in and around the blower housing and fan itself. Long story short, they blamed me for spilling water or some liquid substance on it and would not honor the warranty. But they finally did come back after I had to become an Azzhole with them about it and gave me a new sapphire dual fan card for a discounted price,,, (which I still mine with to this day  ) and was the best they could do he said. However it was there crappy designed fans that were leaking.

I also do computer repair for a living..... it was the fan bearing grease of sorts.

hi guys what is the best driver version for r9 390x on windows 7 64?

[MinermanNC]

hi guys what is the best driver version for r9 390x on windows 7 64?

I have been using the latest drivers with no issues.... some may argue others are better.... but for me its the latest.

On my r9 390 I am getting 315 hashes at stock settings.

Edit: Something peculiar is going on tho... maybe some massive farm joined the network....

ok, flypool just hit a block!!

Hashing has nothing to do with it.

There is an overhead of z transactions that seem to delay t transactions.  After 35 minutes block found, and then another, but i still have transactions with 0 confirmations...


Yes, in 50537 came my money,  118851 B, big block!

ya you may be right on that, I just checked Poli and I have 3 pending deposits all from different time points and sitting a 1 confirmation!

something fishy here. crap I hope there is not an issue or bug! or broken chain, I have a lot to sell yet

EDIT: just got another deposit and all are confirming now  4 in all, weird
