how much is dev fees at these miner???

All the values you see are already with fee deducted.

He finally reduced it to a reasonable 2.5%, but was running at 10% in earlier versions. Most of the gains in his last two releases have probably been from him reducing his fee.

how much is dev fees at these miner???

optiminer just updated the changelog on his github repo saying it's 2.5%

Version 1.6.0 released! 

[1.6.0] Asm support for GCN 1 devices.
[1.6.0] Reduced CPU utilization.
[1.6.0] Fix segfault on reconnect.
[1.6.0] Version and Os exported in monitoring.

Speed increase about 3% for newer cards, the GCN 1 cards should see a much higher increase with the asm kernel now.

5% increase on my stock rx 470 (xfx true oc) on ubuntu 14.04 with amdgpu-pro 16.50 (netting me roughly ~262.5sols/s now, compared to ~250sols/s with 1.5.0)
Just as a side-note, i setup 1.5.0 when it got released and never had to reboot/restart any rig (hardware or software).

Just upgraded my linux boxes to 1.6.0. Looks like a solid and reliable build so far. Getting an increase across the board. At -i 7 cards are doing:
RX470 8G - 288
Rx480 8G -301
Fury X - 452
Fury Pro - 470
R9 390 - 365

How long have you been using your -i 7 ? mostly out of curiosity, i'm wondering whether that's just as stable as -i 6 on stock cards.
But more importantly, have you also compared your Watt/Sol ratio between -i 6 and -i7 ?

@optiminer

would be nice if you can do any work on NV, after nicehash stoped developing (and releasing their code to opensource as nheqminer 0.5b) ewbf (aka claymore brother   ) also lost interest to do more

anyway in windows tahiti cards are now a bit faster then with latest claymore

[charles2k]

Good job.
Under Linux with 270X cards better than Claymore 11.1 - 183s/s netto (and much less invalid shares)
also better for 280X cards - 272s/s

I've been using -i 7 for about a week now.

Good question on Watt/Sol ratio. I had not thought of that! I have wattmeters and will be at the warehouse tomorrow so I will run a test.

Hey blackops! Just chatted with you on the other forum. I've looked at power vs intensity, and at least at the "auto" intensity and higher, there is virtually no difference in power consumption, at least on my Nanos. I see a small rate gain with higher intensity, but I favor stability over a couple sols/s. With 120+ GPUs, it doesn't take very many GPUs hanging to wipe out any hash rate gain, for me anyway.

Yes, that's a lot of GPU's, I see why you are set up for stability.

-i 7 is pretty stable so far, but you're right on the downside of a card hanging, especially if it is at night.  It's fun to chase a few extra solutions per sec, but I'm in it for making money, not for bragging rights.

I just counted, I'm only at 60 GPU's....it might be time to go shopping! But, I want to wait just a little longer until the Vega cards come out - either they will be much better, or the Nano's will come down in price.

Humble minds think alike! Been thinking along the same lines. However, from what I've seen from the AMD tease at CES, HBM2 does *not* have higher memory bandwidth - they doubled the memory clock, but cut the bus width in half. That means the global memory reads done in Equihash will probably not improve *at all*, although the higher mem clock should help the slot writes (relatively small writes) a good bit, but there are much fewer of those. Anyway, only a real mining run with them will tell.

I have switched to Linux ( ubuntu 16.04.1) but have been experiencing my screen not being recognized between switching rigs ( plug in hdmi in one rig and plugging back into same gpu I started with on another rig ) also on startup I have seen my screen not be recognized.
Here's what I did:
install ubuntu
Reboot
Sudo apt update
Sudo apt dist-upgrade
Reboot
Sudo install new amd 16.50
Reboot
Run miner, see gains 
Move to next rig repeat
Came back to the first rig and screen isn't recognized.
Missing anything?

I know i'm not answering exactly what you expect, but how does that matter ?
Can't you use ssh to admin your rigs ?
Or the issue isn't about administration but rather about the miner not working because the screen is not recognized ?
=> My setup is 100% headless, no fake hdmi or anything and it works like a charm.

HELLO! WHAT WORKS  bat FILE WATCHDOG IN WINDOWS WITH AUTORESTART MINER IF ANY SOMETHING WITH ONE OF GPU?THANKS. ONE OF GPU CRASH IN 4-8 HOURS on all rigs. 1.5.0 IT WAS GOOD THIS.

[rayday11]

I am getting this error with 1.6:

OpenCL error: CreateProgram base (CL_INVALID_BINARY)

1.5 worked fine. Any Ideas?

=> My setup is 100% headless, no fake hdmi or anything and it works like a charm.

Agreed - headless is the way to go. There's an issue with the way xorg works in the new versions of Ubuntu. I have found that installing 3 packages makes it work well.

This is what I do:
install xorg xserver-xorg-legacy xserver-xorg-video-dummy

Edit the config file for xorg-legacy:
/etc/X11/Xwrapper.config

delete the last line:
allowed_users=console

insert at end of file:
allowed_users=anybody
needs_root_rights=yes

then set up the xserver-xorg-video-dummy

There's a bit more to getting the headless fully working in a screen, but this gives you a start. I don't want to keep flogging my build guide, you can probably find a link in a previous post if you want. It took me a while to figure it out, but once you get full headless going it's wonderful.

So, I checked the difference between "-i 6" and "-i 7" on my rx 470 (xfx true oc). TL;DR : nothing changed (sols/s, watt, ..). So I reverted back to the default "-i 6".
This might have a better outcome with different GPUs but I guess optiminer did a pretty good choice at picking the intensity parameters.

I tend to get slightly less performance out of the GPU that my monitor is hooked to, although it is a XFX R9 380x vs the rest of the cards in the system are just ASUS R9 380 Strix.  If I were to switch it to headless would I gain a little extra performance off of that GPU?    I'm not positive the less performance is due to the monitor being hooked to it or if the 380x has less performance but I would think if anything it should be more than the 380.
