Thanks, sorry for the more questions but:
Check for compute switch in the driver, by default it is NOT set to compute - Can you tell me where this is, looked it up, can't find anything.

27 is pretty low for RX570, try to find better bios settings. - can you provide a link to better options?

Odd situation.

Have a rig with 3 x RX570 4GB.  Was getting 27Mh/s with Claymore 10.6.

Had to change rig to different board and hard drive.  Board is the same, hard drive is slightly different (slower, but didn't think this mattered).
Same amount or RAM *GB, same pagefile, 16GB, same divers, same version of windows but now only getting 20Mh/s.

ANy ideas?  Really frustrated.

Drivers version is the latest, 18.2 blockchain from amd site.
Bios is modded the same
"UberMix v3.1

777000000000000022CC1C00AD615C41C0590E152ECC8608006007000B031420FA8900A00300000 010122F3FBA354"

What are your Memory Clock settings?
I have mine at 2150 and the Core clock at 1244 and it just crashes the machine after mod.
I have set -h at 1024 and 960, both crash the machine.

I've got Gigabyte RX570 cards, with Samsung memory.  Trying to mod isn't working.
Once I change the Strap values the card is no long recognized by the sytem, even though it was working
fine beforehand.  Blockchain drivers are installed and working, is there anything else I need to do?

Tried modding the card myself and also modding using https://anorak.tech/t/gigabyte-rx-570-aorus/34867 mods.
Neither worked.

Currently mining Monero at 770 H/s and trying to get up to 900.

TIA

Samsung GDDR5 - 4GB.

Interesting thing is of the 3 cards, 2 have Crossfire enabled and one has it disabled.
What should it be?

When I clock is currently with afterburner, just clocking the memory, as soon as the miner
connects to the pool the rig crashes and the OS becomes unresponsive.  I'm on Win10.

Anybody know what I can do to improve performance in my rig

Have 3 x RX570 4GB.  Am running v 11.2 with the -h set to 896.
Card is clocked to 1350 (1250 is standard) and the miner never seems to get it to rin over the 1200Mhz range.
I chance the -h to 1400 and increase the Mem clock on the card but this just crashed the rig.
There are not other options set in my config file.
I'm getting 670 H/s on each card currently.

I have the latest blockchain drivers installed, catalyst 15.2 and afterburner.

Thanks

Guys,
New to mining, have 3 x RX 570 4GB. 
Edited config file for like below:

-xpool stratum+ssl://xmr-eu1.nanopool.org:14433
-xwal *myaddress*
-xpsw x

-allpools 1
-h 800
-dmem 1
-tt 75

Currently only getting hash rate of 650 per card.  What changes do I need to make to improve performance?
No overclocking yet.

Thanks, am playing wit them now.  Any idea how I get paid of when?
All I can see is that I'm getting shares but after two days nothing.
MY wallet is a monerujo phone wallet.
Should I be using just one pool?

Just easy  ---->   ADDRESS.7850/mysecret

so you found a worker called 7850 beneath your statistics
mysecret you have to put in to change your payout limit
you dont need a valid email-address

-----------snip-----------
To be able to change your settings you must use the email optional parameter with every miner you have, and it's value must be the same. To find examples how to mine with email using your miner, please check the Help page (EMAIL / YOUR_EMAIL is what you should replace with your email). You can use a real email to receive offline workers notifications from the pool or just a secret word to access the settings.
---------snap------------

So I'm getting 'incorrect address'.
I have two workers, but one I'm using tsiv miner on an Nvidia card, I have no email address parameter in that config file,
it says all workers should have this, you think that can cause the issue?  
It also says I need a 10 rating, which I'm not sure I have.

Thanks for this.  When you say (secret), I'm not 100% sure what you mean?
Also, what is my worker?  Just a nickname?

Do I need a valid email address?

Hi,

Just started mining and so have not invested any HW yet.  Have a MSI Radeon HD 7850 which only does 240H/s, I know this is not enough but just
want to make sure I can set this up on my PC before I buy cards.  I'm using the 1.7 version of the AMD driver which I don't think
works with Claymore 10.2, so I'm using 9.7, which works fine.  Is the below syntax ok?

NsGpuCNMiner.exe -o stratum+ssl://xmr-eu1.nanopool.org:14433 -u 48dJamRDpppZ3Nh6W14EPaA794G6iuwQJ2Px8XsJarGjhiE1LQNSbXsgsLLQaZGoLnSwegv9bx5ocXr NbNADtkHgCag3XGp -allpools 1 -p x

I've also being mining from my CPUs (8 x 17) but so far have received zero payment into my account.
Only started 2 days ago.

Also, which cards are best for me.  I don't want get a huge rig, just something small with maybe 3-4 GPUs, so shorter cards are better.
