Propably you forgot enable compute mode in AMD control panel.

Still i advice you to stay where you are if your system is stable!

Hi Guys

I'm wondering if you can help me with this.

my rig keeps rebooting shortly after the miner starts on this and I cant figure out why.

I'm using 4 x vegas
1200w PSU
latest blockchain drivers
32gb virtual mem
8gb ram

I've got the fans set manually it wattman to 3000rpm min
I've disabled all other over underclocking and am just trying to run this as a baseline test before I start playing with the other settings

The miner starts up, runs for a few seconds and then the rig just resets and wattman resets everything.

The rig works brilliantly on cryptonote but I fancied giving some eth dual mining a try for a while.

Anything that would normally cause this type of behaviour?

@oblione

4x vegas dual mining with no undervolt? That could be using more than 1200W. Check your consumption because you could be hitting the limits of your PSU.

@syncis

Not sure about cutting down on instances, but for the disk make sure you turn off the recycle bin, and if you're feeling adventurous you could turn off restore points. Each one uses 10% of the drive IIRC. Also the Claymore logs can add up after a while.

Do you get a high percentage of invalid shares? The OC is not stable, GPU does not perform calculations properly. Do the fine tuning. I would recommend 1100-1150 MHz @ 900mV for core, 2000-2100 MHz @ 875-925 mV for VRAM and -ethi 16, -dcri 27.

1. Just a speculation: the DAG of the previously mined coin is not unloaded from VRAM and when generating new DAG for newly-switched coin, the GPU runs out of memory, i.e. you mine ETH, the DAG is ~2.18GB, later the pool switches your task to ETC, with a ~2.25GB DAG. 2.18+2.25>4 GB, out of memory error, OpenCL crashes, 0 hashrate on all GPUs. That might be a Linux-sensitive issue, haven't met it on Windows.
Since you are mining on MPH, you are switching between 4 coins: ETH, ETC, EXP and Musicoin. Is all the hassle worthy the extra 5-10% you get over mining a single chain? Factor in all the time your rigs are not effectively mining.
BTW, I would mine only ETH or ETC. Screw Expanse and Musicoin, first is scammy, later is laggard.

It is bad. You would be better off with Equihash coins - Zcash or ZenCash through EBWF or DSTM, mining on an exchange address with autosell option. Now Nicehash-Equihash looks more profitable in the short term than Zcash or ZenCash mining because there are many buyers for Equihash (BTC Gold), but that will fade away in a couple weeks.
I'd take ZenCash, as payouts would be more frequent, every day. Bittrex has autosell option, it sells the coins that get into your wallet for BTC. Or you can just hold your coins, waiting for a convenient exit price.
Don't forget about Power Limit, set it at 75-90%.

Hi guys,

I'm mining with MSI P106 x6.
However, 2 of my cards are not able to run at the fan speed that i've set in AF, which is 65% fan speed.

It appear to be 65% for the first 5 minutes when the miner first launched, then it turn to 0%, sooner it turn to 100% fan speed for 1 of the fan.

My concern is will running 100% fan speed on my GPU kill the card faster ?

As it generates more noise and consume more electricity, can someone share how can i fix this ?

Back then, when i was mining zcash with EWBF miner, i don't have this problem.

I've attempted to reseat all the risers. It appears to b fine for 2-3 hours. after that it went back to normal for the same GPU.

Someone please help. Thanks all.

Looks like drivers reset because OC too high.  Dial back the OC.

Hey guys,

Running a 6X480's 4G Nitro + Crimson Drivers, H81 BTC Pro, 8gb ram Win 10 Claymore V10.1 Virtual mem 32gb. Oc through Afterburner 2k 1150 (been stable for well over a month)

Have two rigs running with the same settings and they have been golden for the last 4 weeks. Around 28.5 MH while dual mining Lbry in Nicehash Pool. Then yesterday my second rig crashed and had to be manually reset (couldn't log on team viewer).

But for some reason now I can't run my rig for more than 5 minutes without it getting a hard crash... I've tried running V10 but that also seems to be crashing now. Not really sure what could or might have changed to be causing it to crash now.

Any ideas as to what could have happened? What can I check or change?

Following settings for start.bat
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setX GPU_SINGLE_ALLOC_PERCENT 100

.exe etc....
-allpools 1 -estale 0 -esm 3 -ftime 10 -cvddc 980 -dcri 42 -ttdcr 79 -ttli 81 -tstop 85


Edit: Is there a new blockchain driver? AMD settings are saying I should update to 17.11.1 from 17.30. What is the Enable compute options under global settings? I'm not seeing that as an option anywhere
