I have RX460 2GB x4 GPU, mobo GA-880G-UD3H, windows 10 pr3.
I DL latest drivers.

vars are set,
-i 2,2,2,2 -tt 60.

miner is not showing GPU temp and FAN SPEED.
It shows them only for GPU0.
Sometimes it does show them.

Sometimes it shows all zero or GPU0 temp=0 fanspeed=0,
later shows actual values (for ex. 50C / 40%).


Sometimes it hungs,
Sometimes it can work for hours with high hashrate (for these GPUs 530 h/s all together).

Switched to onboard hd4250, - no changes.
Plugging in hdmi to vga converter with no display attached - no changes.

What I did wrong?
What is workaround for this?

I solved some freezing, after reading FAQ.

It seems that this happens only with RDP connection.
When I use teamviewer everything is ok.
But TW is bad solution for some reason.
There should be some regestry tweaks to make it work with RDP.

It is definitely problem of insufficient coding.
Miner can not do it's work correctly.
It can not wake up and initialise GPUs properly, with usage of proper system functions.
There'is no doubt that OpenCL MUST work with monitor-less stations, for batch processing video render and so on.
There must be some OS API to wake and init gpu correctly in RDP session regardless of display connected or not.

hi guys.

sry i'm a newbie to this.
have tried to get the "Claymore's ZCash AMD GPU Miner v12.6" running on my win10 machine just for testing with following options:


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

ZecMiner64.exe -zpool ssl://eu1-zcash.flypool.org:3443 -zwal waaletIDY.test -zpsw x -i 3

but it only says unknown options and unspezified pool.

can you please give me a hint.

i'm having a geforce 920M if it helps to resolve the issue.

thanks

setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

ZecMiner64.exe -zpool ssl://eu1-zcash.flypool.org:3443 -zwal YOURWALLETID.RIGNAME -zpsw x -i 3

That is the right speed. However, power consumption is quite a lot.

You need to gain more activity. You can read more about activity and member groups in the sticky in this subforum, but basically you get a max of 14 activity points every two week period.
