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

[golden0707]

Hi ALL!

So, having 4*R9 280X with 8 Gb RAM and 32 Gb Virtual mem. CM 12.0 runs only with -i 2 stable. With -i 3 or -i 4 after ~1 hr. one card hows 0 hash and miner restarts . With default -i ( -i 6) miner writes low virtual mem. and lower intensity to 5 and i get same situation as with -i 3 , -i 4. Only way to run it stable is -i 2 option ? My hash rate lower by ~10-15 hashes per card with this intensity. Anyone in this situation ?

pwpwpw,thesaltonsea and me ownmind. We all in one boat. Claymore or someone, can you explain this situation? Please, take a look at problem.

I got 4 rigs with 290/290x, 3 of them on win10 - cant run under -i 8 (always drops to 5) and one rig with 290 with win7 runs fine eith -i 8.

Set environment variables:

GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

modded rx 470 -285 h/s (80W in Afterburner), modded rx480 - 305 h/s (86W in Afterburner), modded HD7950 - 245 h/s (around 110w I think). Very nice results Claymore, you made equihash most profitable algo at nicehash again.

would you pls post your settings?

rx470 4gb: one has 1256 mhz and other has 1260 mhz stock clocks, mem clock is 1750 mhz. Voltage is 985 mV.
rx480 8gb: core clock is 1266 mhz stock and mem clock is 2000 mhz. Voltage is 961 mV.
hd7950 3gb: core clock is 900 mhz, mem clock is 1250 mhz all stock. Voltage is 956 mV.

Thanks alot. but one thing i dont get i was searching and searching and then i gaved up.
In Afterburner the Core Voltage (mV) is set to 0. what do i change there? i can change from -100 to +100.

BR

You change mVolts. If your card is running on 1120 mV and you change it to -100 then you get 1020 mV. But I couldn't lower it more so I changed it in gpu's bios to 985 mV

you watch energy consumption not there
Energy consumption jumps from 80 to 120 (for example)
You watch the maximum value
1200/1940 Vcore - 950 mv

You are probablly right. I will measure it at the wall then.

Hi. yes its same for everyone with 280x .... And i have other problem only one of the 280x is hashing normally, the others are with 30+ sols less ...

[theoulis]

very nice job with V12.
but now 280x with the 3GB can accept only -i5. 290 with 4GB can accept -i6. gpu mem starts to be a bottleneck!

What kind of CPU you have ?

do u have a link for the mod pls.

Thank you.

is it save to change it to -100? sry for the noob question but i have no clue of undervolting and what will happen if i undervolt to much.

[Redhotdog]

Constantly getting "GPU #1 returned incorrect data!" on v12.0
v11.1 works fine.
Virtual memory size = 16Gb

SET GPU_FORCE_64BIT_PTR 1
SET GPU_MAX_HEAP_SIZE 100
SET GPU_USE_SYNC_OBJECTS 1
SET GPU_MAX_ALLOC_PERCENT 100
SET GPU_SINGLE_ALLOC_PERCENT 100

are set

UPD. In my case they are set via SETX but I think it doesn't matter.

depends of the card, some will hang.Some may work @ -100 even.

[AzzAz]

This:
GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100
must be entered this way:
SET GPU_FORCE_64BIT_PTR=1
SET GPU_MAX_HEAP_SIZE=100
SET GPU_USE_SYNC_OBJECTS=1
SET GPU_MAX_ALLOC_PERCENT=100
SET GPU_SINGLE_ALLOC_PERCENT=100

@Claymore: can it be put into readme this way? For newcomers.

ok if it only will hang its ok. i thought it will burn something maybe.

4x 280x, tried to run -i 0 all cards still fail, looked at v11.1 had settings at i 6,6,4,5, now I'm trying 5,5,0,1 with asm 1,1,0,1 so  the 3rd card is completely turned down, doing 210H/s (way worse than V11), the rest do, 290 290 270, this is barely faster but somehow one card simply dies with this new miner and another can only go with low setting, using 40GB virtual memory, 4GB system ram, tried the cpu with and without OC, no difference, wiped and reinstalled drivers no difference, meanwhile v11.1 flawless so it's not a physical loose plug or something.

Same here as well. Gpu 1 incorrect data. 7970. Finally pulled the card and put in a 390x. All is well. Funny was that after running v12. That 7970 does same now on v11.1. Think it wiped out my card.  Def some bugs in the new release. Save yourself some headaches and move to v11.1 if you can't get stability. At least it will run more than a few hours.  Also same rig when it would drop to 0 hash on a different random card before replacing 7970 it would start getting socket errors. Then pc was no longer accessible via team viewer. Had to manually reboot Computer. Great effort claymore. I am getting over 400 sols on 390x. Those seem to have no issues running v12.

Also rolled back to 11.1
My rig consists of 3 RX470 and one R9 390 (the above mentioned GPU 1). Tried to increase voltage. Nothing helped.

[fr4nkthetank]

for the incorrect data thingy, I had the same problem with 280x but at i -2 it seems to be good.  One card is good at -3.  So lower i it should work.

I have a 6 x Fury rig that also started behaving real odd. I keep getting 'GPU 3' crashing for no reason. Driver reinstall, and stock settings have not helped.

[PandaPanda!]

My farm is a mess with v12.0 - i'm moving back to v11.1 until claymore sorts out all the issues with crashing GPUs etc.
