The big VTC Vertcoin settings thread

[BorisTheSpider]

Vertcoin https://bitcointalk.org/index.php?topic=404364.0 uses a new (not scrypt, and not scrypt-jane) PoW, which results in about half your normal hashrate, and requires different cgminer settings and a modded cgminer.

The modded algorithm is harder to mine than normal scrypt, and requires lowered thread concurrency and possibly lowered intensity, memclock and core clocks depending on your setup.

The latest miners are always linked from http://www.vertcoin.org


I thought I'd start a thread to collect best configs and peoples hashrates with them.

Here are mine:

R9 290:


"gpu-engine" : "1000",
"gpu-memclock" : "1500",
"gpu-powertune" : "20",
"intensity" : "13",
"temp-overheat" : "80",
"temp-cutoff" : "85",
"temp-hysteresis" : "3",
"vectors" : "1",
"worksize" : "512",
"lookup-gap" : "2",
"thread-concurrency" : "24550"

These are getting me about 330KH/s per GPU when using the PC.

When not using the PC for other stuff, I increase intensity to 20 and get 400KH/s per GPU.

A 7970, 7950 and any other configs and hashrates achieved would be great.

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

[BorisTheSpider]

7850 from Rasetsu:

--thread-concurrency 2048 --lookup-gap 2 --gpu-engine 1100 --gpu-memclock 1000 --gpu-powertune 20 -w 256 -I 13 -g 1

Gives 170KH/s

From Bufius, dev of the modded cgminer:

- for now, TC needs to be lowered to ~80% of normal scrypt (as a starting point).

- try to change TC to something like 256*x (for me this works OK)
  - for my 7950s i use 19712 = 256*77 without HW errors @1000/1500
  - 5770 is at 4096, also no HW errors @ 925/1350

I get about 700 kh/s with two 280x and this config.

One Powercolor R9 280x
One Sapphire R9 280x Vapor-X

[XBATTO]

Powercolor HD7950 PCS+ 256 kh/s

set GPU_MAX_ALLOC_PERCENT=100
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt -o "ADDRESS:PORT" -u "USER" -p "PASSWORD" --shaders 1792 --worksize 256 --thread-concurrency 16384 -g 1 -I 19 --gpu-fan 100

I am getting 256.6 Kh/s (couple hours average) with Intensity set to 19. Increasing to 20 causes instability with this Vertcoin miner (without gain in hashrate).
I am living in Canada and it's winter. The window near my computers stays open    The rig alone is heating the whole apartment 

[co42]

Getting around around 307 kh/s with 7950, XFX Double D Black Edition FX-795A-TDBC. No HWs so far even with this TC. Now if only I could get on a stable pool..

-I 20 -w 256 --thread-concurrency 19712  --gpu-powertune 10 --gpu-engine 1050 --gpu-memclock 1500

I am getting a stable 240 kh/s with your configuration and the same gpu ...
Have you done something else ?

[marcje]

How much RAM do you guys have in your system?

[gabrielknight]

anyone here is using the windows one? (http://kilovolt.co.uk/Vertcoin/Vertcoin-CGMinerAleks_NR3.zip)

if you try to set the windows one tc to above 4k, it will claim not enough memory and just quit.
if you set below 4k, it will result in all hardware errors.

Tried it with 270x, 280x, different pc same result.
It's just doesn't work.

Not anything significant that I can think of. I did crash with intensity 20 after a few hours though, switched to I 19 and so far running stable at 300 kh/s. I have Catalyst 13.9 and I'm on Win7.

It mines, but I only get rejects... I must be doing something wrong. My setup:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
TIMEOUT 10
C:\cgminer\cgminer.exe --verbose --scrypt -o stratum+tcp://eu2.bitcrush.info:3444 -u x -p x -I 13 -w 256 --gpu-fan 58,52 -g 2 -v 1 --lookup-gap 2 --gpu-engine 1020,1000 --gpu-memclock 1500,1500 --shaders 2048,2048 --thread-concurrency 8193,8193 --gpu-powertune -20,-20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

Are you using the modded cgminer (it is specific to vertcoin because of the different PoW):

I am now getting 450 * 4  on 4 * XFX R9 290 ThreadConcurrency 27000 Intensity 20

My normal hashrate is around 880/ card

Awesome - that's better than me, please post your full config.

I am at work so cant access the config file ( will have to use my Phone to do teamviewer hehe ) Anyways my config is exactly the same as

http://www.holynerdvana.com/2013/11/litecoin-mining-with-r9-290-and-r9-290x.html.   I just changed Thread Concurrency

[BorisTheSpider]

Thanks, tried but can't get past 400KH/s per R9 290 here, you must have golden cards!

[aleks648]

Code:

--scrypt -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 0

Gets me 650 KHs on my 7990.

Whats your normal hashrate ? which company cards do you have ?  mine are XFX ( One of the card is 20KHz faster lol  rest all are same)
Also, How much RAM do you have in your system. When I was on 4GB I was not able to get 880. I was on 820.. Increasing RAM helped me to increase thread concurrency and 815 became 880
