You should look into COSS.

As I said above, one of the possible changing variables (everything else is fixed by deepfreeze) was the cards temperature. Raising the card fan speed didn't solve the issue. They all sit at about ~55ºc (hbm 65ºc).  


The drop is about 300 h/s on each of the 4 cards. It appears to happen simultaneously on all cards.

I am using a software called DeepFreeze on two 4xvega56 mining rigs to freeze any changes in my working virgin windows/vega installation.   



The freeze state boots with a fresh windows installation, no updates whatsoever,  with the  23aug blockchain drivers manually installed by device manager, and no regedit mods.  A virgin installation.  It always boots in this state.



After booting, I have scripts that apply the regedit powerplay mods, reboots the drivers using CRU.exe, uses devcon.exe to disable/enable the cards a few times in a row, and finally applies a custom overdriventool.exe profile , followed by xmr-stack-amd.exe. I never had a hashrate drop in one week of running, tested across many reboots.  Always static performance.  until now....   



One of the rigs, after running perfectly for one week without hashrate drops, its now beginning to drop the hashrate after a few hours.  Again, windows installation is frozen to the same state as one week ago. No updates, no driver changes.   This hashrate drop purely caused by another variable affecting the cards.  The other twin rig, has no problems whatsoever.

I have tried without success to:
- Decrease core/mem speed
- Increase Fan RPM by a lot


My latest try was to increase the voltages, which were already on the high side (0.980v).



If someone has a clue as to why 4 perfectly running vegas started to hashrate drop in a frozen windows installation, please share!

Hey mike

How are you dealing with the hashrate drop those card have?  are you running a batch do reset the cards?

One mistake on my post. You need to set setx behind the parameters like this:

setx GPU_MAX_ALLOC_PERCENT 100
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

Open poloniex, click your xmr deposit wallet, copy the wallet address.

In the file epools.txt add at the bottom:

In the file Config.txt, delete everything in there. Must be empty for now.

On your start.bat, add this:


Now run the start.bat

thats it.


Everytime you need to add extra pools, add them to the epools.txt
Everytime you need to add arguments (set temperatures, voltages etc) add them to the config.txt

what arguments to make Cast work on rx570's ?

I'm seeing 800h/s on average using claymore 1080gpu/1950mem @825mv  ~60w (gpu-z)

On the 290's I'm seeing 780h/s 1000/1100 89w (gpu-z) on average but with high spikes to 120w

I'm testing this miner and its using more power than xmr-stack for only ~50h/s more.    Anyone else noticed the same?

What kind of traffic? Ethereum has been handling ~twice the transactions of bitcoin for weeks now. Maybe you meant dollar volume?

Interesting. I have the same cards.  How much ETH Mh/s do you get?   Mine do 28.8 Mh/s @ 1080/1950  837mv  (gpu-z 70ish watts).   

Hello guys

ETH veteran here, but wanting some feedback of these cards on XMR

Could you share your hashrates and wattages for XMR?


thanks!

did you toggle the compute switch in the driver options?

how do myetherwallets stand with this new update?  anything on our side that we have to do?

pretty good if undervolting is your scene.  Also, quiet despite the size!  you can get from 27.5 to 30mh/s depending on the voltage you want to run at.

@claymore

Every version since 9.4  won't allow me to connect via stratum




9.4 works fine.  Exactly the same batch file.   Did something change?

on one rig, this driver restored the full hashrate (25 -> 27.8 ). On the second rig, it restored much less (25 -> 26.8 ).

One has windows 10, the other windows 10 creators edition.

Edit: nevermind. Claymore miner cannot set nor read clocks/fans/voltages for this driver.  Clocks were lower.

Power to hash ratio is more important right now.  I'm staying with the old driver until this driver works and undervolts as expected.

Describe the hacks, and how each one of them relates do Ethereum. Then explain how third party apps/websites getting hacked are synonymous with the Ethereum blockchain getting hacked.


I understand people have personal investments and the underlying motives of such statements are clear as day, but this fact should not lower the common reasoning capability of a community down to the point you are lowering it. 

With that being said, the ITX are also awesome.
