will you optimize the code for vega - fiji ? fury x is showing lot of potential on this coin --- atm 19 cpd but high power ... if i want to cut power i can get half power @ 14 cpd.

May I know your driver version? Thanks! I got only 10~cpd.

try blockchain or 16.9.2 drivers.
you should get around 15.5cpd for fury x at stock frequency.

Thanks! blockchain cannot work. 16.9.2 only got 9.45x2 on my pro duo. I'll try win10 this weekend.

How much u can get from a Vega 64?

How much u can get from a Vega 64?

I got result 14.5 CPD on Vega 56 on Windows 10 and Crimson 17.9.2 drivers.
Vega support and target auto switch (for difficulty > 11) will be available in xpmclient 10.2 beta in next 2 days.

[eXtremal]

WARNING: difficulty grows and can reach 11!
All previous xpmclient versions automatically switch off when work with difficulty 11 will be received!
You can follow 2 ways:

1. Manually edit config.txt when difficulty reach 10.99+

# Target Cunningham chain length, default = auto (adjust to difficulty)
target = "11";


# Sieve layers number, optimal value is target*2; default = auto (target*2)
width = "22";

2. Use new version 10.2-beta.

...

New xpmclient version 10.2 beta available HERE. New features:
- Radeon RX Vega support. See config.txt

# Platform:
#  "amd": AMD GCN cards
#  "amd legacy": AMD HD5xxx & HD6xxx cards
#  "amd vega": AMD Vega cards
#  "nvidia": NVidia Maxwell cards
platform = "amd vega";

With "good" drivers you can get 14,5-15 CPD on Vega56 and more than 16 CPD with Vega64. What is "good" drivers? Need more statistic from miner users.

- Difficulty target automatic switch. For use this feature, edit config.txt:

# Target Cunningham chain length, default = auto (adjust to difficulty)
target = "auto";

# Sieve layers number, optimal value is target*2; default = auto (target*2)
width = "auto";

With this settings miner automatically switch to target=11 when difficulty reach 10.991.

Remember, that CPD with target 11 will be less by 28-29 times than you see with target=10!

Im getting less CPD with the new miner v10.2. Less ~-15% in all my gpus. I have 290x, 290, rx470 and others. Im using the blockchain driver.
With the 9.4.1 version, i get 14,5 cpd on the 290x's, but with the 10.2 version im only getting 10 ou 10,5 cpd


Do you recommend a specific driver version?

Im doing experiments with other drivers

xpmclient 9.4.1 has kernel compiled with old catalyst 14.6 driver (blockchain driver not optimal for xpm), new 10.2 miner don't have that.
Miner version 10.x uses file names like kernelxpm_gpu0.cl for first GPU, kernelxpm_gpu1.cl for second, etc. You can try copy kernel from miner 9.4.1 to directory with 10.2 and rename it according to rules, but it can be incompatible (for example it not works on linux with amdgpu-pro drivers) or use another drivers.

Do you recommend a specific driver version?

For Hawaii  (R9 290X) optimal driver is old Catalyst 14.6. R9 390X not supported by this driver, I recommend use Catalyst 15.12 with replaced amdocl* dll from 14.6 (tested on ubuntu 14.04).
For rx470 almost all Crimson 16.x is good, 17.x and linux amdgpu-pro gives poor performance (less than 7 CPD on RX470), don't use it.

Any improvement for 10.2 in terms of cpd?

[abrgeza]

Any improvement for 10.2 in terms of cpd?

1-2% on my fury x, fury nitro and rx580.

What exactly driver need for HD7970 (R9 280)?
http://www.guru3d.com/files-categories/videocards-ati-catalyst-vista-win-7.html
On AMD Catalyst 14.6 RC2 (14.200.1004.0 June 20) driver two HD7970 get me only 0.50 chains/day.
On Crimson 15.12 driver three HD7970 get me 17 chains/day.

Do we need new compiled kernel for those settings?

0.5 chains/day is not properly result, may be different version drivers conflict. Try it on newly installed OS.

Yes.

For me Fury X 9.4.1 :15-16 CPD,10.2 :13-14 CPD

works fine with blockchain driver.
all my fury x cards are downclocked to 1018MHz and downvolted.
my fury nitro and rx580 are at stock frequency but downvolted.

[Dragomax]

abrgeza What is your  core voltage?What did downvolt ?

[ivcelmik]

Can someone share a config for Fury X maibe driver version and windows version

Thx in advance

[abrgeza]

abrgeza What is your  core voltage?What did downvolt ?

It is a simple bios mod.

Do we need to change also sievePerRound to 7 ?
