Hi,
I got a decent Hashrate on my first rig of AMR R9 Fury (and Fury x) with de default setting
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fibb.co%2FkC9w5y&t=663&c=9uDotGNCDQh8MA)
But on my second rig with only 8 x Fury X, I got half the hashrate (380 h/s)
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fibb.co%2Fm31Jky&t=663&c=HEF_ngMlbyBaMQ)
The only difference I see is the collum (Used) , 1.0 GB
Same default setting in the app
Same driver on both rig
compute mode activated on both
page file 64 gb on SSD both
Why I have this behavior ?
I would double-check device settings: threads, raw intensity, and local work size.
Most likely the default raw intensity is too high for your second rig.
After many test, the defaut value is the best (always run only on Cryptonight Heavy)
Fury X: (with 64 core)
Threads = 1
Raw Intensity = 64
Local Work Size = 8
Stripped Index = 1
Fury : (with 56 core)
Threads = 1
Raw Intensity = 56
Local Work Size = 8
Stripped Index = 1
But sometime, it run @ 340 H/s and use 1.0 Gb ram and other time run @ 770 H/s and use 2.0 Gb ram (collum (Used) on the dashboard)
I also have instability after fee hour of work.
The same rig was stable with de lastest XMR STAK in same algo.
I continue to investigate why I don't have consistency...
Thanks
