Since start, 1.7 is more stable than Claymore, no problems at all.
Thank you Optiminer.
I have been running stable for several weeks with AMD-pro 16.60 and Opti 1.6.2 on 7 GPU rig. It was not always so, and I have been struggling with stability for the last couple of months before finding a stable configuration for my hardware. A second 7 GPU rig has been more problematic but I think I finally have it stable as well.
I have also seen issues with mixing cards (Nitro and XFX Rx 480ās 8 GB on one rig). However, was able to get them playing together by placing the least stable GPU directly on the mobo. I find there is a big difference in what cards you place in what slot x16 vs x1 and what riser you use (x1 or full x16 powered). GPUās that drop I have in x16 slots, if they continue to drop I use a x16 powered riser instead of a x1 powered riser if I cant plug directly into mobo. I know it should not matter but is settled down my hardware and I have not seen any more problems.
I just upgraded to 1.7.0 today but so far all seems fine.
What are the hashrate on rx480? I am around 320, at least I found some stability right now, anyone with more sols?
What you describe sounds like Vega. It seems the RX500 is series not Vega yet. I found this

So, I would expect 10% more on equihash at most.
Vega architecture might indeed make a big difference. It depends a lot on how the cache and bus changes affects the memory throughput achieved with equihash.

Well, the link (thanks!) is the first confirmation Iāve seen that there will, indeed, be a RX500 series released before Vega, although, as you said, it aināt much to shout about. You obviously know much more about Vegaās potential, but I suspect the sequential row reads each round arenāt going to see much, if any, improvement. The slot writes, however, should be a lot faster. Iām thinking atomics, too, may get a big boost. Guess weāll have to wait and see. For me, Iām looking for a noticeable drop in Nano prices as the big win for price/performance after the Vega release.
Anyone know where to find older drivers for AMDGPU-PRO on linux?

hello bro
i am currently use 1.6 since i have problem with 1.7ā¦
and now the problem isā¦when i started mining the coin, it will take around 24 hours only and the miner will be stop .
what was happen actually?no error i thinkā¦thanks
@Optiminer
Should we expect a new. faster version?
@agis further optimizations are hard but I still have some ongoing work in that direction. Cannot do any prediction whether that will be successful or not.
No worries. Good to know youāre still working on this project
Stability is more important at this point.
can watchdog be integrated so it restarts the program by itself?
On average 1.7 freezes once in less than 2 days (maybe 36hr) on Ubuntu Linux 16.04
With current prices, it is NOT good.
I used Opti from the beginning, but if stability (on Linux) is not fixed soon, I will have to switch.
Thanks
Have you tried āāpci-mode 0ā. The default now is ā2ā, while ā0ā is the same as v1.6.x.
Hi, @Optiminer, I tried to run R9 Fury X using v 1.7, however the PC always hang. Btw, I installed driver version 16.40. According to your documents at readme, is it complusory to use fgrlx 15.30.3? I cannot find this version driver at AMD website. Pls advise how to install in Ubuntu under command line then?
Hi Optiminer,
I like your miner for Zcash. Stable and reliable for me with my 7-GPU rigs. Any chance we will see even minor speed improvements in coming weeks (specifically for RX480 8gb)? Thanks,

I have some 7-GPU rigs that are very stable as well, it took me the better part of a couple months to get them that way. However, the miner software was in a rapid state of flux at that time, and things have now stabilized. I do have one rig for whatever reason is not stable with more than six but have a few mixed GPUās on that one. I am going to try for eight by using the M.2 slot for a GPU. Seems reasonable with the right mobo. I know the MSI mobo will not work, and is also a bit temperamental with 7 GPUās but does work.
Does anyone know how to set a second pool option in Optiminer? I want it to automatically connect to the second pool if it canāt connect to the first.
There is no such capability available for Optiminer. Failover has been requested a couple of times, but it seems itās not enough of a priority for Optiminer to implement it.

I may switch over to Claymore for that feature alone

I havenāt run his stuff in a long time, but I know he has no love of linux, so his minerās performance on linux is usually not up to par with Windows. YMMV 
Hi Optiminer,
Do you have an ETA on an Nvidia miner? Thank you.
