Hmmm... so it's not just my 980TI that freezes for nearly 30 seconds when the difficulty is changed by the stratum on Suprnova when doing Decred (at 14:09:45).

Any active pools besides exapool?  p2pool seems to be down for the last few days.  Miningpoolhub has been offline for a couple months and who knows how long since Suprnova was up

Further testing....
980TI
Yiimp reports roughly the same hash rate (must run at least diff 2 which causes reported hash rate to vary depending on luck solving the job).
Suprnova poolside (diff 1) reports a MAX of around 2.65GH with an avg of roughly 2.45 at -i 31 (and I did let it run for over an hour and kept an eye on it the entire time) using Mod9 whereas Mod7 poolside shows 2.7-3.5 averaging around 3.1 (data taken today and from DAYS of monitoring).  Mod9 -i 31.9 was averaging about 2.3GH (see offtopic discussion at bottom of post for more info).


750TI
-i 24.5 1339mhz (primary display) Mod7 614MH, Mod9 620     (Mod7 -i 24.2 reports about 602 with MUCH less screen lag)
I am getting better poolside reports with Mod9 580-720 vs 470-630 Mod7.  I am also significantly more likely to solve a job with Mod9.  This is just an eyeball estimate but solve rate seems to have gone from 60-75% to around 85% on my 750TI.  It is uncommon on Mod9 to have a string of 3 or more jobs fail to find a solution whereas Mod7 often had runs of 5-7+.  The 980 TI also reports a higher solve rate on Mod9 but it's not as profound.



Conclusion: 
On my equipment, Mod9 appears to be a gain on compute 5.0 but something is broken on 5.2 cards, the poolside hash as reported on Suprnova is significantly lower.
Also, the --show-diff flag is broken in Mod9.  It always shows (diff 0.000) for every solution.  This flag was also broken in the 1.5% miner fee version from a few days ago.



Offtopic:  For the 980TI I actually get better throughput using -i 31 than -i 31.9 (as reported poolside).  The typical job time is about .8 seconds vs 1.1-1.2 for the higher intensity.  These numbers I can see when I have a run of jobs for which it did not find a solution (don't use -q).  I am a bit more likely to find a solution meeting the difficulty requirement of the job at the higher intensity but the slower processing time lowers throughput.  This made me scratch my head more than a little bit...why the higher solve rate at the higher intensity?  But I've watched the numbers stream past for hours.  Tried -i 31.5 and it yields same results as 31.9 for throughput.

980 TI -i 31 1641mhz I'm getting about 3285 which is +40ish vs Mod#7. -i 31.9 bumps it to 3292.

Is it possible to solo mine?  I've updated to the latest wallet and tried 4-5 different versions of ccminer (NVidia cards) and all I get are "JPSON call falled, unable to get work".

So I tried the 1.5% fee miner posted a couple pages back.  On my 980TI (using exact same config), it was about 1.2% faster than SP mod #7.  

What really shocked me was seeing the stratum difficulty actually change while mining on Suprnova.  It started at 1, then went to 2, then 4 then 8.  When it switched from "fee mining" to my personal mining the stratum difficulty reset to 1 but then never increased.  I've tried creating new miners and I can't get the difficulty to go above 1.  Whether I mine with the 980 at 3.2GH or pair with a 750TI for a total close to 3.9GH the difficulty never changes.  Anyone have any suggestions on how to fix my stuck stratum difficulty?

The bots on Bittrex are working HARD to push the price down.

I haven't been able to solo mine with an SP build since build 69.  I was solo mining a quark coin.  You can download it at https://github.com/sp-hash/ccminer/releases .  I'm sure this version is missing lots of speed enhancements and might not even support the coin you are trying to mine, but, it was the last I could solo mine against the wallet.  The release notes for build 70 mention a fix for solo mining a neoscrypt coin.  I'd start there and proceed to newer releases.


**edit: added b70 info

This would explain why I often have 3-8 consecutive submits without a Yes!  I found no solutions that met this preset minimum, it wasn't that I didn't do the work.  (single 750TI setup, for now)

On Decred I've been running it for 2 weeks at 1329, stable as a rock.  A few hours ago I tweaked it up to 1368 (+180) and its been solid.  On Quark it would crash the driver and usually recover every 24-36 hours at the lower OC

I'll reply back if I have any issues at this OC.  I decided to try to push it a little more in response to what fenomenhaa said in post #10485.

Decred #4 received.  750 TI at 1368 core went from 528 on tpruvot 1.7.4 to 625 on sp miner

Well done.  Will probably drop the intensity back just a tad to improve responsiveness when I'm using the pc.


edit:  -i 24 restored system responsiveness and still coming in at 613.

On 11/25 I moved 30,034 MUE from miningpoolhub to Bittrex.  I checked today and it still hasn't arrived so I went to check the block explorer.  The "official" explorer is offline so I checked the one at cryptoid and it looks like there has been a huge fork.  Miningpoolhub appears to be almost exactly 400 blocks behind.

This is what I use:

set app=ccminer.exe
set algo=quark
set address=stratum+tcp://xxxx:port#
set user1=xxx.x1    (your username and workername for the pool)
set user2=xxx.x2
set password=x     (your worker password)
:start
  start "gpu0" /min %app% -a %algo% -s 1 -d 0 -i 19 -R 3 -o %address% -u %user1% -p %password%
  start "gpu1" /min %app% -a %algo% -s 1 -d 1 -i 19 -R 3 -o %address% -u %user2% -p %password%
  timeout 600 /nobreak
  taskkill /im %app% /f
goto start



It will autokill and restart every 10 minutes.  Very handy for those pools that have a vardiff that doesn't play nice.

Maybe I should say I've not been able to solo mine on Quark algo since b54.  I just tried b56, it just sits there doing nothing.... just like in your screenshot.  B57 does not generate an error message for me, but it also just sits there doing nothing.

Build 54 is the last sp_ build that will solo mine against your wallet.  I have not tried B63, but I'm assuming it will also fail.  I have tried every build from 54 to 62. 

I haven't been able to solo mine (only tried quark algo) since build 54 on sp_ version with my 750 ti.  I have tried with every build since 54.  I can solo with the latest djm build.  Anyone else having this issue or have suggestions?

4% pool fee on Verters?  That's enough to get me to move.

First off, thanks to the coders for all their hard work.  It is very appreciated.

Since Build 54, I have been unable to solo mine quark on my 750 TI.  The recent builds all work just fine with pools, but 54 was the last that will connect to my wallet and actually mine.  Just wondering if anyone else has had this happen.
