That is what my own tests indicate as well. That’s why I brought up the overly aggressive overclock as a possible thing causing it but the person said they had stock cards with stock bios so if they’re still having a problem I don’t know what it could be.
It could be drivers. amdgpupro from kernel 4.9r3 seems to be much better than stock.
Good news from the Windows front: I have successfully run my equihash kernel under Windows and it produced a correct test result! All that is left is converting part of the networking code before I should be able to release a Windows version of the miner!
awesome! looking forward to a amount of speed/watts comparison with claymore 
@Optiminer
Have you had any luck with Nvidia miner, few dev are working on open source silent army optimization, but progress is slow
maybe fix linux first before moving to other os/specs

Optiminer why spend the time on Windows support while Claymore already has significantly higher performance and significantly lower fees on Claymore’s ZEC miner? Seems like that gap has already been filled for Windows while those of us using Linux have lower performance and higher fees…

I agree. He won’t beat Claymore speed or his devfee. Why not focus on fastest linux? If your linux version doesn’t beat his Windows version, I’m 100% on claymores and creating a windows version won’t make me switch unless you somehow get over 10% faster than him.

Half the people here barely know how miners work. They’re more then likely dropping GPUs due to bad or unstable OCs with higher utilization or have power delivery issues. You can’t find the problem because it’s not on your end. When people talk about miners ‘frying their systems’ they setup a faulty system and it of course doesn’t go well.

you might be right about a good part of the people running a miner
and yes i am not very familiar with miners but i have 30 year experience with computer systems and know how to debug a system and believe me i did debug the system to the best of my knowledge before i posted here.
But what shows me that it is the miner is clearly the fact that claymore is working without dropping a gpu.
Optiminer is dropping a gpu after some time, about a 5 hour range of working properly
Claymore is stressing the gpu more then optiminer so it should not happen with optiminer but rather with claymore however it does not.
My hardware is stock, no modifications
Different miners stress GPUs in different ways. It’s entirely possible for power delivery or OCs not being stable with one miner, but stable with another.
Stress != higher hashrate. You can have one miner that’s more efficient then another, so it produces more hash at less power. Power usage is a pretty good indicator of utilization, even that can be different between miners though.
One more voice asking that Optiminer focus on Linux.
To Optiminer: hopefully the Windows project doesn’t interfere with future Linux upgrades for those of us who have been with you since day one. Windows will only matter if you can restart the “arms race” with Claymore. If you have him beat doing something so far unreleased then I’ll be looking forward to your future Linux releases.

are private z-addr working yet?
I used the early version of Claymore’s miner when he supported ubuntu but switched to optiminer later. Claymore also has some command-line options to restart upon GPU failures so it seems the challenge with GPU stability is not unique to Optiminer.
I’m using Optiminer v0.4.0 on 2 racks with 6 r9 390’s each. I utilize the watchdog feature to reboot my rig if needed. I’ve been running this version only for a couple of days now and the watchdog feature kicked in once on one rig and twice on the other. This feature has kept my rigs producing without manual intervention, very much appreciated. An improvement would be for the miner to sense when the GPU is non-responsive and reset the connections itself rather then rebooting the whole rig. Also, it would be nice to have some of the fancy options that Claymore offers as well such as the control over intensity, temperature, GPU clock speed, and fan speed!

No crashes, freezes, or GPU failures here.
I have the rigs listed below, and optiminer 0.4.0 has been running since released with no problems
A. 1 x R9 380
B. 3 x R9 380X
C. 4 x RX470 + 1 x RX480

I am testing 0.4.0 since yesterday and this morning 2 cards were stopped, number 1 and number 3. The first few times it might be for the temperature, but he raised the speed of the fans repeatedly, without success. I carry a percentage of 100% 99% of successful solutions, so that invalid solutions is not the problem.
If I wanted to run Windows I would already be using the claymore miner. I wanna run Linux! Optiminer, please stay focused on your Linux code!

Running optiminer since the initial release on all my rigs. Works great and no drops like some reported.! Hope a new linux version is released soon

Really all people here want a better linux version.
I think opiminer will release a windows version because he can gain a higer hashrate on windows due to better
AMD drivers for windows. This is why claymore stopped releasing his linux version.
no not because of higher hashrate , but the reason is a greedy bustard who wants also the windows market thats it …
