The big VTC Vertcoin settings thread

[quarkkid]

Ok managed to get 1 rig working, however my other (pretty much identical) rig will no work without a really low TC and gets loads of HW , if i increase the TC the GPU's will disable and i get a Error -5 cl and nothing happens..... like i said everything the same , cards, drivers....

I ran into a similar problem. I think there was a problem with the version of the modified cgminer software I downloaded. Delete and reinstall with the following steps for gpu mining with windows:

1) Download modified cgminer scrypt:  https://www.dropbox.com/s/ksgtrltpah1eqes/Vertcoin-CGMinerAleksNR3.zip
     
2) Use notepad++ to create a .txt file, then convert extension to .bat file.

This is the code I've been using for dual x280's:

setx GPU_MAX_ALLOC_PERCENT 200
cgminer.exe --scrypt  -o stratum+tcp://us.bitcrush.info:3444 -u Weblogin.Worker -p Worker password -I 12 -v 1 -w 256 --thread-concurrency 8191

This is the code I've been using for dual 6950's:

setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt  -o stratum+tcp://us.bitcrush.info:3444 -u Weblogin.Worker -p Worker password -I 12 -v 1 -w 256 --thread-concurrency 4096

*these are the TC's I found to work the best. Anything higher than 4096 will result in error. Any intensity >12, and your mining shares won't be accepted.

3) Run created .bat file

x280 = 275-350 kH/s
6950 = 125-175 kH/s

Goodluck

R9 280x from Nonny12:

cgminer.exe --scrypt -o POOL-ADDRESS -u username -p password -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20,-20 --gpu-fan 59,50 --temp-overheat 85,85 --temp-cutoff 90,90 --gpu-memclock 1500,1500 --gpu-engine 1000,1000 --thread-concurrency 8193

I have 4 card R9 280x, only 3 card run and 1 fail.

If I down --thread-concurrency 6000, them run but with big number HW.

Some one help!

Thanks.

For r9 270 Any ideas? I got only 170 KH

my miner with 4 x 280x is running with moded 3.7.2 cgminer an the following config

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
--scrypt -o server -u user -p pw -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-engine 1020 --gpu-memclock 1600 --thread-concurrency 8191

3 x 350 kh/s
1 x 230 kh/s (monitor conect on this device)

no rejects
hw errors 0.01% no problem i think

i'm using 4gb of mem if you have more u maybe need to tweak my settings

good luck

I just check follow your config.
Result:
3 x 350Khz/s
1 x Off

I'll come back with VTC someday.
So, I want to say thanks to you.
Good luck!

The only thing I've needed to change for Vertcoin is thread concurrency. These seem to be the optimal ones for the cards I've tried so far:
R9 290: 24550
7950: 19712
5850: 5120

Thanks for the 5850 TC. 5120 seems to be the only one that works.

I'm using

--scrypt -I 13 -g 2 -w 256 --thread-concurrency 2000 --gpu-powertune 0 for my r9 270 ( Gigabyte) I've got 200 KH on my computer but in pool is wrtitten 50 KH  

How many coins shoul I mine per hour with 200 KH and with 50KH ? Should I change my settings or should I change the pool

How many coins shoul I mine per hour with 200 KH and with 50KH ? Should I change my settings or should I change the pool

with the current diff i think around 60-70 coins a day with 200 kh/s

how long do u monitor pool stats ? if you only have 50 for hours the stat is maybe wrong or u have a lot of hw errors or rejects
if not and you don't get enough coins i would change the pool to test things out

R290 (XFX black edition):
-I 20 -core 1000 -mem 1500 (Used Msi Afterburner to set clocks and aux voltage +100; Fan at 100%) Gets 400kh/s. Crashes after any cgminer restart, lol

To avoid crashing  (R9 290) on cgminer restart:

In the adl.c file around line 472, just before the ADL_Overdrive5_FanSpeed_Get call, add a line above:
ga->DefFanSpeedValue.iSpeedType=ADL_DL_FANCTRL_SPEED_TYPE_PERCENT;

and run make again.

289Kh/s out a 280x dunno if this is any thing new but it was to me LOL

You are lucky)
I have 99% hw on my giga 280x, if set i 13. I try it with any parameters... Normal work only with i 12...

[mik_druid]

How about modyfied cudaminer for this?

[badbonez]

sooo, I´m running a Gigabyte r9 280x rev. 2 Catalyst 13.12

My Settings:

Code:

color 02
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
"D:\Program Files (x86)\Vertcoin-CGMinerAleks_NR3\cgminer.exe" --scrypt -o stratum+tcp://us.bitcrush.info:3444 -u -p -w 256 -I 13 -g 1 --lookup-gap 2 --gpu-powertune -20 --gpu-fan 59 --temp-overheat 85 --temp-cutoff 90 --gpu-memclock 1500 --gpu-engine 1100 --thread-concurrency 8212 (marginal difference in range between 8190 to 8250)

I am getting exactly 304.7 kh/s
with the normal cgminer I am getting about 730 kh/s

My problem:

• It spits to many rejects out with an ratio of 12% (!!!). I tried playing with:
  
  thread concurrency, no effect - 70% of 8192 = HW´s on mass
  
  trying with -g 2 or higher was unsuccessful
  
  lowering core clock resulted in lower hash speed (memclock the same)
  
  lowering intensity induced lower hash speed

I really don´t know where the problem could be. Please help me The rejection rate is a catastrophe!

Problem solved. I changed the pool, now everything is running smooth!

What hashrate are you getting?

I have Gigabyte R9 280x, v3 my settings are:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://s.la.vertcoin.org:3333 -u -p -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 8192

And I am getting around ~300 kh/s - I'm used to seeing 720 kh/s.  I've tried -g 1 and changing thread-concurrency but there's not much change.  There are so many variables with this I'm hoping another Gigabyte user will share their settings.

Oh, I have underclocked the card, voltage set to 1.075.

Thanks!

2 x Sapphire HD 7970 Dual-X

Getting ~ 335-345 kH/s per card or 670-690 kH/s total using...

Code:

cgminer --scrypt -o stratum+tcp://pool:port -u user.worker -p password --gpu-platform 0 -w 256 -v 1 -I 13 -g 2 -l 1 -T --thread-concurrency 8192

My clocks are set externally at:

1000 MHz core @ 1.15v
1640 MHz mem @ 1.625v

edit - with regular Scrypt, these cards each get about 690 kH/s with the same cgminer settings.

[snogcel]

2 x 290x settings. Wow this miner is really picky about TC, this was the only one that didn't result in HW at 20 intensity. Seeing 415Kh/sec and 460Kh/sec with these, might play around with the GPU Engine later on...

Are you running 4gb RAM? I can't seem to it mining correctly with only 4gb at any thread concurrency. Too high and I get error enqueueing kernel error and too low gives HW errors.

No, running 8GB ram on my miner. I'm using linux, but have this set up in my .sh file:

#!/bin/bash
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1

Hopefully that helps =)

For r9 270 Any ideas? I got only 170 KH

-I 20 -g 1 --gpu-memclock 1500 --gpu-engine 1100 --thread-concurrency 14208

gives me ~215 Kh/s

[theletterb]

My sapphire 7950 on a computer with 4gb ddr2 cannot go past -i 13 without getting hardware errors, I've tried thread-concurrencies for hours. Currently it's only doing 160kh/s

My XFX 7950 is fine and pulling about 200kh/s   --thread-concurrency 16384 -i 19

I've yet to get a 5870 to run at any -i 11 without errors 

I had some success (250kh/s per card!!) with sapphire 7950 dual-x cards using the linux vertminer client (v0.5.2) built from github and the following config - I've only undervolted gpu and mem to 1.125v (as an FYI)

--scrypt-vert --lookup-gap 2 -I 20 -w 256 --thread-concurrency 16384 --gpu-engine 1100 --gpu-memclock 1500

I also set  --temp-target 77 --auto-fan and my fans run at about 50%

the difference between HW errors and none has been the --lookup-gap switch
