Can you add an option to serialise the startup of each card? I think this would really help!

As a workaround if your cards fail try loading multiple instances of the program with a few cards on each and wait until the memory uses on task manger drops low and then load another batch of cards.

Also drop the memory freq on startup, when you load its drawing a huge amount from the risers filling those cards.....

Also try setting your virtual memory to over the total size of mem on the cards

I need to know what values to allocate for the best result. At the value -dmem 1 and -dmem 0, I have poor results.
For this command with -dmem 1:
NsGpuCNMiner.exe -xpool stratum + tcp:/xlc.my-mine.su: 3333 --xwal LuBjjphj3teSxLC7GxdFyFG1CXwfU3SLLUxPiGgsVJZ6iiu2aJuT5cNUMxQ3xuCQNkWpMcaYnyHfL4F cuJrTUvgE4Bda8Pd -xpsw x --allpools 1

With value -dmem 0: https://imgur.com/ptdAfbr

Then it changed the value to -h 832:
NsGpuCNMiner.exe -xpool stratum + tcp:/xlc.my-mine.su: 3333 --xwal LuBjjphj3teSxLC7GxdFyFG1CXwfU3SLLUxPiGgsVJZ6iiu2aJuT5cNUMxQ3xuCQNkWpMcaYnyHfL4F cuJrTUvgE4Bda8Pd -xpsw x --allpools 1 -h 832
The result: https://imgur.com/MJSPDBH
The results are good but I think they can be better. What is the best value of -h for AMD 4 x rx480?

These lines are only for testing because I wanted to try out the new Claymore CryptoNote AMD GPU Miner v10.2 Beta - POOL miner if it is more powerful than v9.7. XLC coins do not interest me at this time. About that value -h 832 I read in READme!!! document. But, when I do not set the value, there is low power, somewhere around 320 H/s for the card.

I needed to know what are the best settings for the AMD rx480 graphics card and what approximate result can I expect and if v10.2 is more powerful or I can stay for my v9.7 verified. That's all.

Edit: Electroneum I mined when the price was higher than it is now 436 Satoshi. Good project but I don't mining ETN now.

please clear nicehash

That's the perfect news. I will watch the new version in anticipation. Claymore you are doing a very useful job for us miners.

I have the same problem when I try auto tune the rig with my 570/470 my 570s are fine the 470 hashes at 300 something on my rig with 470 4gb and 8gb cards the rates are all over the place 340 to 600 nothing stable I tried setting the virtual memory th 50gb that didn't help so I'm using gatelessgate I don't get it claymore's miners are usually the best this new xmr miner sucks I can't get this stable on any of my rigs

I tried this miner AMDXMRMiner v0.65b even older v0.64b screen flashes black and the miner stops. I do not know where the problem may be. For me, this miner does not work. I had to reduce the intensity because the comp is freezing, followed by a restart or BSOD.  Here's my startup file:
amdxmrminer.exe -p ....... -w ...... -psw x -i 5
And here I add the picture: https://imgur.com/bLyFPot
I also read the tutorial at https://www.amdxmrminer.com/ but did not help.
I'm staying with the Claymore CryptoNote AMD GPU Miner.

For everybody who has a low hashrate issue with RX 400/500 cards with v.10.2. First unzip 9.7 and then unzip 10.2 in 9.7 folder, or just add Data.bin file from 9.7 into 10.2 folder.
