I really like the stability and the speed, here it comes, but,
The stale share rate is really bad.
I have all AMD cards, on another miner I get <1 % stale shares.
PhoenixMiner gets 5% to 10% stale shares.

This really needs to be looked at. The additional hash rate that I get using Phoenix is eaten up
with stale shares. I'm loosing .35% of 5 to 10% of all the shares submitted.

I know this can be solved, I've seen it solved elsewhere.

thanks

something wrong with your setup. im using pheonix and get like 1% stales.

it's not the miner.

Sorry dude. nothing wrong with my miner.
You don't know what you're talking about.

I can change to Claymore with EXACTLY SAME SETTINGS.
I get < 1% stale.
Change to Phonex and I get between 5 and 10%.
So, buzz off and let the experts address this.
I didn't ask for amateur help.
5 to 10% is very high... I have with Claymore <1%. With Phoenix 1,5-3%...
I think that this is because of memory timings. Phoenix use memory another way...
Very possible.
I can lower the stale shares some by reducing the intensity.
I can get it around 2 to 5% if I give up hash rate.
But that negates the extra speed that Phoenix gives me.
My issue is if I get the higher hashes that Phoenix offers the stale shares goes up.

I had about 4 to 8% on Claymore before the 11.4 release.
They claimed they fixed the stale share issue. And man did they. I immediately went
to < 1% without doing any adjusting.

So, I know it can be done.
I want the increased speed that Phoenix offers and the very low stale shares.
If I get the same hash rate on Phoenix and Claymore but Claymore stale rate is <1 % and Phoenix
is 2 to 5% I'm better off going to Claymore. I had rather use Phoenix if they can address this issue.
How you reached more speed on Phoenix? For me on my RX 580 8Gb cards Claymore gives about 0,5% more with right dcri tune.

I can't explain why Phoenix is faster. I don't know technically what they have done.
I also have all RX 580's a few are 4gb and some are 8gb. 6 of them.
I had 182.5 mh/s on Claymore. I got 186.2 on Phoenix, without any memory errors or crashes.
But to try to attempt to get the stale shares down I'm now at the same speed as Claymore but with
a much higher stale share rate.

I guess every rig is somewhat different even with the same type cards.
If Phoenix could get the same stale rate and offer me 4 mh/s more than Claymore why would I ever
go back to Claymore.
