HD 7990 is getting around 400 h/s

Sorry getting around 570 h/s

Having a HD8990 with no customization (stock bios/stock settings) sitting on 600 h/s

Hi! I can't setup zcash mining in ethOS 1.2.3.
I have 13 rx580, but miner detect rx480, and when I start it tempreture go too high. How can I fix it?
Set -i 1, no result

[johiro]

What Vega cards are similar to R9 390?

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

True. Which cards are best energy-saver? What do you think of Vega cards?

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

You have to create a bat file with the following:

Code:

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

Just replace YOURWALLETID with your Zcash Wallet ID. And change RIGNAME for anything you want something like rig1.

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?

======later======

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.

Are you using driver 16.12.2?
For 4xx cards (Polaris) Crimson 16.12.2 is recommended.

For 4xx cards (Polaris) Crimson 16.12.2 is recommended.

I'm using latest driver.
for 5 hours so far working well.
Except for temp/fan RDP malfunctioning.

Is there any speed up in the latest driver?

Miner shows the same speed.
I'm new to mining, and for now I care about stable functioning.
I can not tell precise data.

Don't use RDP, it resides on too higher level to work with GPU properly.
I recommend to use RealVNC

claymore do you think you can add R9 FURY +mixed GPUs to allow zcash mining with a driver newer than 16.3.2 the 16.3.2 is just too bad doesnt allow undervolting doesnt performs well in games at all, the lack of control on this driver sucks. if you could add support for at leats 16.8.1 or 16.8.2 or Blockchain driver it would be the ebst thing you havent  supported for Fiji since you added it to the miner

top speeds for polaris reached around ver 11 or so...

16.10.4 is better for 4xx as it doesn't require bios signature patch and also one of the few versions that have no issues with accidental 100% fan on various miners(weird, but true) running Cryptonight kernels...

What hashrate are you getting with the 460 cards?

[YIz]

The hashrate has dropped a bit on the latest version using Fiji chips. Is it normal or should I consider switching over to Vega?

Hi all

I am having problems with one of my rigs and need some help. I am not new to mining, nor to this thread (just never needed to post before), but I certainly won't pretend to be an expert either. The rig I have an issue with (runs 3 x Sapphire Nitro+ 480 and 1 x 470) has been running well for about 7 months or so. It was running on V12.5 without any issue, however it crashed the other day and hasn't worked correctly since. The machine runs fine, Claymores V12.5 and V12.6 are both acting the same, when I start mining it recognises all the cards etc but then it mainly lists incorrect data, line after line. Please see the screenshot.
Is someone able to point me to the route of the problem?

Thank you
