I found this suggestion from a guy named wiskeywiskey on another board, he adds a registry value for each gpu.. found where to add the values, but I couldn't figure out how to add the key.  Apparently, this solves the painfully slow time between switching from graphics mode to compute mode if you're not using blockchain drivers.  I'm wondering if this could help the crashing problem?


Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e968-e325-11ce-bfc1-08002be10318}\0000] "KMD_EnableInternalLargePage"=dword:00000002
And for 0001, 0002, etc.

thanks whiskeyx2 (recent w10 april update... and my 2nd gpu would not go back to 31 mh/s... added (new entry) the kmd setting + restart... and i m good to go)

I have a very similar problem.  I had (2) seven card rigs running fairly stable for 3 or 4 months.  Monday morning 5/21 I got notification from ethermine that one of my rigs was off line, looking at the stats the other was only working at half capacity. (2 separate machines both took a significant hit within a 1/2 hour of each other.  Looking at both machines checking for any leaking capacitors, checking connections I rebooted, both machines once through the bios, windows would only go to a black screen.

My machines are both Asus Z270a Prime mobo, both have 8 gigs of ram, both have plenty of power, and I'm using MSI RX 580 armor cards. (all bios modded, I used anorak tech bio's and then backed off clocks a little for card life with AMD catalyst wattman.  I had been using the latest AMD drivers circa 12/31/2017 in compute mode.  I was hashing between 29 and 30 for each card, they were nice and cool, and I was content.  I am using unregistered win 10 Pro (an old version I own.. so I had to go through a bunch of updates upon install)  On both of the rigs I right after I built them I was getting a windows message "task host is preventing background tasks"  I youTubed a fix where you changed a HEX key value in start from 2 to 4, and this stopped it.

I toggled the PSUs Monday morning and came back this weekend, to maintenance the machines and trouble shoot.

First off, I updated bios double checked all my settings 4G encoding, Gen 2 etc. Unplugging all the cards, the pc booted right up no problems, I DL claymores latest miner, scrubbed Cayalyst drivers and DL the latest and started plugging in GPUs.  1 card no problem, 2 cards no problem, 3 cards machine slowing.. like 20 seconds of wading through mouse button clicks to switch cards to compute mode.  4 cards over a minute per mouse click... right click on screen (wait over a minute) left click AMD catalyst control center (wait 2 minutes) click gobal settings (wait 3 minutes)

At four cards installed, I started claymores.. no issues.  Everything running ok.

Installing the 5th card, Windows became unusable.  like 4 or 5 minutes between responses. sometimes freezing altogether.

I can switch to any three cards and all is ok, so I don't suspect riser card issues, but I have riser cards to swap out, maybe I'll try them. 
Before this event, I had maybe a 12 second lag per screen switching to compute mode with 7 cards installed. I"m assuming this is normal?

I'm looking for advice,
thanks.

I was able to transfer funds from the additional accounts generated by mining directly to my wallet address to the initial account created by mining to wallet address.  -no problem, no charge.
I changed my -dwal to my XXXXXX_XX  PASL account #
The website is so sluggish, I can't update stats, but the miner is back up and running

at the bottom of the list of my transactions, is the "key change" entry.  (im not sure if this just lists that my new accoutn is activated?)

how do I sent the balance from my other 4 accounts that were mined each containing 12.25 PASL while I slept?
what does the change key message mean?  do I have to change a key somewhere?

Please forgive me, I'm new to mining.
I created a PSAL wallet, and mined with fairpool to achieve 12.25 PASL.
My wallet shows the transaction(s) with more than one 12.25 PASL deposit, but each one seems to generate a new account. 
Each one lists "without payload"
and each transaction directs me to change key.
How do I get into my PASL account?  I can't figure it out.

Yes,
You can dual mine ETH and PASL with claymore's dual miner.
At the moment, the only operational pool for PASL I could find was Fairpool's PASL pool.
I set up a (3) Rx 580 rig this morning.
I am mining ETH on ethermine.org, and PASL on fairpool    https://pasl.fairpool.xyz/

When I was only mining ETH at ethermine, I was hashing at 86.6 Mh/s  yielding about 70 shares an hour
When I configured dual mining, my ETH hashrate dropped to about  54.7 Mh/s. and 45 shares/hour. My PASL hash rate about 1633 Mh/s. yielding 280 shares in the first hour. So (at least on my rig) PASL takes about 38% away from ETH mining.
Fairpool is very sluggish this morning.  I've only been able to see my miner on the pool for a very little bit.. the rest of the time website unable to reload.  (I think a lot of people are having your idea, since PASL is currently #1 slot at whattomine.com)

Other thoughts..
I couldnt get my miner to show up in fairpool until I added -dcoin PASC in front of hte -dpool settings. dont forget that!
