Yeah, I was not using 2 gpu threads...things are looking better now...still had to underclock due to a hard hang but didnt lose hashrate. 

I am only getting 187khs per card.....?

I have a lower gpu OC because when I get it up around 1100 I start getting hard hangs on sgminer 4.1.0 with no errors to troubleshoot.  I lowered my gpu OC and that fixed the issues.

EDIT:  I meant vertminer 0.5.2

Thanks, I will give this a try and see what happens!

Sorry, whats the URL for that?

Hey all.  Does anyone have "the perfect" working config for this miner software for 270x cards mining scrypt-n?  There seems to be a lot of how to guides out there but nothing seems to help and there is a lot of unorganized info out there (no config wiki like the Litecoin page).  I have tested and tested with different configs and I cant seem to get a very good hashrate or if I do, I start to see hardware errors.  And to boot,  I built a second rig (same exact drivers and cards) and it gives me a totally different hashrate than my older miner.  

Here is my config, any help would be appreciated  (This gives me around 212khs and some HW errors and WU ~90-95% -----my goal....higher hashrate with 0 HW and 90% or higher WU):

"gpu-engine" : "1045",
"gpu-memclock" : "1500",
"intensity" : "18",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "12288",
"temp-cutoff" : "90",
"expiry" : "30",
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"device" : "0,1",
"scrypt-vert" : true,


EDIT:  I am also undervolted to 1106.

I have read a few things online that this miner software will mine scrypt-n but I have been unable to find anyone actually trying it and what their configs are?!?! 
I have 270x's and was wondering if anyone has tried this, and if so did you have success and what was your config??  I would much prefer this to vertminer 0.5.2 (kev) for MANY reasons - to include stability and I get a 20-30K hashrate increase by using sgminer over cgminer, etc.  Thanks.

Merc - is there anyway you can put up on the website the est profit stat for the two multiports (scrypt-n and scrypt)?  You know, the one that says how much btc/1mh/s stat.  Per my ignorance, if there is something up already and I dont see it, or an easy way to calculate this, please let me know.

Nevermind, I got it. 

Hey, can you reply back your exact config you have that enabled you to get to 215Kh/s?  Thx.

Merc:  What do you mean when  you say that the PANDA coin crashed?  Also, secondly, when do you believe it will come back again so profits will go back up? 
I am running a 1.7-1.8MH/s rig on cgminer, compiled and switched to vertminer and now only run about 700Kh/s?!  Is that normal and if so...what do you think I should "average" as a profit.  It's hard for me to gauge this when I am used to cgminer when you can describe everything in .012btc/1Mh/s for example.....seems to be COMPLETELY different in vertminer.  I know you are busy, but could please clarify that a bit for me.  Also, on my rig mentioned, I am running 4 R9 270x GPU's that get me to that ~700K mark BUT I am running into HW errors.  It's not crashing vertminer, nor idling or stalling the gpu's so I have been ignoring it for the past day or two (when I started vertminer) but if you have any suggestions on this as well.....I am all ears because I plan on working on this issue this weekend.  Thanks, and sorry for the long post.

Ok, I got it compiled and its slow to start up but when it does, it see's my four gpu's but doesnt start them up...then come the errors.  Any clue?  Also, since you are a fellow linux guy, is there a better, more efficient way to reach you?  If you dont mind, I would like to get this up and running very soon.  Thx.

Hey man, I ran thru those steps and at the very end...when you run ./buildit.sh.....i get an error that says ./configure does not exist.  Did you run into this problem?  How did you fix it?  FYI - I also have cgminer running on this linux distro as well (Xubuntu 13.10).  My vision was to have both cgminer and vertminer.  Cgminer is currently up and running so I skipped most of the sdk and amd driver parts.  Please help!

I reviewed this thread and seen no mention of setups for Linux.  Is there support for Linux users as of present for this new miner program?

Pool:  When talking about the KH and the MH, are you referring to the overall miner total or each individual card?  I am running a total of four cards on one rig totaling ~1.8MH.  After reading your post, I set my diff to 256.  In your opinion, is that a good setup for me? For the past week or so (since I have been on your pool) I kept it as X and let your servers decide for me.  Thanks, and keep up the good work....last two payouts have been good.

EDIT:  After running the 256 for about and hour or so...I have noticed two things.  1)I get quite a bit of work restarts.  2)I get quite a bit of detected new block.  This appears to lead me to my concern....cgminer is reporting what appears to be a lot less accepted work since the change.  I am at about .5% reject rate on 1.8MH/s.  Is this normal, or is there currently an issue on your side?  ...OK just looked again and now ive got like 10 straight accepts...it seems to come and go in spirts.  Is this normal?  Thx.

Appears that hash is running off of a script of some sort....I notice on the high profit coins, it SLAMS it with all the hashrate it has.  When the coin is not high profit, it backs off and only runs a portion.  It's definitely something automated...I was thinking it was multiple users rushing from MC or Multpool, but this is something different.  It is acting as a "botnet" of sorts and its DDOSing our pool.

SERVERS ARE ABOUT TO POP...THATS WHAT'S ABOUT TO HAPPEN.  DB WILL GO DOWN, SERVERS WILL BE NON-RESPONSIVE AND WE WILL EFFECTIVELY KILLED ALL SMALL PROFIT COINS.  I HOPE POOL IS PAYING ATTENTION HERE AND ENSURING HE HAS PROPER STOP GAPS IN PLACE.  ONE OF THEM SHOULD BE WORKER SIGN UP, THAT WAY HE CAN CONTROL THE POOL AS FAR AS HOW MUCH HASH IS ALLOWED ON HIS POOL SO THIS CRAP OF "POOL SURGING" STOPS BEFORE EVERYTHING CRASHES AND WE ALL MINE FOR NOTHING.

Now my miner is reporting I CANT process shares any bigger than 64....which sucks....now that the pool is HUGE, my contribution just shrank 10 fold.

If this doesn't get resolved soon, I will leave.  I basically have stopped mining completely at this point.

....because it limits the amount and type of coins you can mine.  If your hash pool gets too big, you will flat line smaller coins, hense lower profits for PPLNS pools.
