The big VTC Vertcoin settings thread

[pkjames]

Anyone else having this problem: http://imgur.com/zr9K0CT

I got Burfius Vertminer-GPU compiled and it runs, but the above is all the display I get.  I don't get the typical cgminer menu and display.  Compiled and running on Xubuntu 12.10.  This guy is the only other guy I have seen that has this exact problem: http://www.reddit.com/r/vertcoin/comments/1x55q9/cant_get_vertminer_to_display_information/

I believe it was mentioned earlier that you need
libncurses5-dev
and recompile

I Have a big problem with 4x r9 290.
One of my 4 gpu is not mining (GPU 0)
Right after running vertminer 5.3.0 graphic driver reports an error. the screen starts to blink and then screen back to normal.
But the verminer says that gpu 0 is mining at 0 khash/s.
Tried different settings with no luck.
My settings are:

--scrypt-vert -o stratum+tcp://stratum.vertco.in:8080 -u user.w3 -p x --thread-concurrency 24550 --lookup-gap 2 --auto-gpu --gpu-engine 800 --gpu-memclock 1250 -w 512 -I 20 --gpu-powertune 20 --auto-fan --gpu-fan 40-85 --temp-overheat 90 --temp-target 70 --temp-cutoff 95 -g 1

system specs:
i5, 8gb ram

Please help!

I had the same problem, you need to reduce your Thread Concurrency until it works.

Where can I download the modified cgminer binary for linux with support for AMD GPU mining?

building my own binary is a bit to risky for me, it took me a while get the current cgminer running and I don't want to break it by installing extra pkg.

Azure Vertcoin Pool - DDOS reisistant P2Pool Node http://cryptopool.cloudapp.net:9171/ No registration - No minimal payout!

To connect to this P2Pool node simply point your miner at: URL: stratum+tcp://cryptopool.cloudapp.net:9171 Username: Your vertcoin address Password: Anything

Fast facts 1. P2Pool nodes are all part of one single, big, distributed pool 2. When any p2pool worker on any node finds a block, everyone on all the nodes gets paid their share 3. There is no pool wallet, and hence no payout threshold. Payments go directly to your wallet 4. The distributed nature of p2pool resists DDoS attacks

Sample Vertminer configuration: cgminer.exe --scrypt -o stratum+tcp://cryptopool.cloudapp.net:9171 -u VbNPoxNeiNg6Bj9RwjjS4GazDbKLgUqNDP -p X

here mine, found some good one

280x toxic = --thread-concurrency 8192 -I 13 gpu clock 1100/memory 1500  powertune 20    300kh/s
7950 vapor-x = --thread-concurrency 8192 -I 13 gpu clock 1100/memory 1250  powertune 20   180kh/s

just remove the -g 2

[Keits82]

im using these settings for cgminer right now

!/bin/bash

export DISPLAY=:0 export
GPU_MAX_ALLOC_PERCENT=100 export
GPU_USE_SYNC_OBJECTS=1

/minutemp/cgminer-3.3.1/cgminer --scrypt -o stratum+tcp://xxx:xxx -u xxx.xxx -p xxx -I 13 -w 256 -g 2 --thread-concurrency 8192 --gpu-fan 85 --gpu-engine 1060,1060,1060,1060,1060,1060,1060,1060

can someone post what settings I must use in vertminer. Cards are 4x Gigabyte 7990 6gb

[kqpahv]

Can anyone please point out what might be going on if Vertminer nearly always starts up with one GPU disabled ? Getting " GPU x failure - disabling GPU x.
It's always a random card out of the 4 cards. I have to restart vertminer anywhere between 5-20x to finally get them all going and even then one card will randomly die at some point and I have to do all the restarting all over again.

Running:
4x 280x
4gb of RAM

 -g2 - I 13 -TC 8192 @ 1040/1500

Lowering TC wouldnt be an option as 8192 is the only value giving me 370+ Khash

[Amph]

try lowering the core


i discovered that the only value that matter is the core, leave everything as it was with the previous settings

[jafkel]

Does anyone know of a vertminer that can run different gpu-threads for 2 different cards in 1 instance?  Because I have an r9 270 which likes 1 thread and a 280x which likes 2.

[kristofabc]

7950 has 1792 shader units, so try setting --shaders 1792 and experiment with a thread concurrency that is a multiple of that, i.e. 3584, 7168, 8960 etc. Also try updating to a newer Catalyst driver set. I got better results on Catalyst 13.9 than the old 13.4 or something I had first.

Thanks man, got +5kh with catalyst 13.9. Not much but hey everything counts
My settings on sapphire dualx 7950 are:
gpu 1023, memory 1225, 1,1v set with sapphire trixx
--shaders 1792 --thread-concurrency 7168 --lookup-gap 0 --I 13 --g 2 --w 286

getting 265 kh

One question, if i add r9 270, can i run two different settings (for different cards) in vertminer?

Always when i got gpu 0 failure it was a problem with too high of thread concurrency. If you set too high gpu threads it freezes the system, same with intensity

you can always use --g 1,2 --engine-core 1000,900 etc to tweak the settings for each individual card.

You cant run two cards on different number of threads (-g) on cgminer. Only Sgminer allows that.

[kristofabc]

Huh, barely got the hang of cgminer. Is it similar at least? Alternatively which card should I buy that will support two gpu threads( budget versions), please don't recommend r9 290 or 280

--shaders 1792 --thread-concurrency 7168 --lookup-gap 0 --I 13 --g 2 --w 286

cant set both shaders and threads.  if you set the tc it ignores the shaders.  if you set only the shaders without the tc if will auto calculate what the tc should be. 

--thread-concurrency:
This tunes the optimal size of work that scrypt can do. It is internally tuned
by cgminer to be the highest reasonable multiple of shaders that it can
allocate on your GPU. Ideally it should be a multiple of your shader count.
vliw5 architecture (R5XXX) would be best at 5x shaders, while VLIW4 (R6xxx and
R7xxx) are best at 4x. Setting thread concurrency overrides anything you put
into --shaders and is ultimately a BETTER way to tune performance.
SUMMARY: Spend lots of time finding the highest value that your device likes
and increases hashrate.

try lowering the core


i discovered that the only value that matter is the core, leave everything as it was with the previous settings

Just to make sure everyone saw this. It's VERY important.

On normal scrypt, my r9 280x's sweetspot is 1085/1500.
I was getting less than 300 Kh/s in vertminer with these values.

LOWERING THE CORE TO 1030 MADE ME GAIN OVER 70Kh/s.
I'm now happily mining away at 370 per card with a total of 4GB of ram...

[JohnnyDaMitch]

LOWERING THE CORE

The core engine frequency that gives highest hashrate will, however, go up proportionate to your memory clock. And what's really interesting, the achievable ratio between the two seems to be dependent on how low a thread concurrency you can get before WU drops off or hardware errors begin. There are places in this state space where it will seem like increasing TC gives you a little extra hashrate, but really you want it low so that you can get effective hashing with the engine clock as high as possible.

Or at least that's what I seem to have observed with my 290's. I'm still not entirely sure - the numbers move in mysterious ways, sometimes.

[zaw]

I got 7850 and R9 270

7850 is running at 180Khash

270 is running at 202

end of the day after reset stats etc.  7850 is doing alot better share count then 270. 7850 I hardly see any stale or rejects. 


I'm having a lot of trouble running 2x CGminer at once.. One will start and another will stop or crash the card.

I let the card idle for 5+min and both will restart fine, sometime.

Its weird how settings are different from one user to another

So would you say that the best results would be achieved by lowering TC while gradually upping core & mem clocks? It would be very interesting to know the sweetspot ratio between the three values.

I mined away happily for 24 hours yesterday on my 6x R9 280x rig with TC@8192, core@1030, mem@1500, -g2, lookup gap 2... giving 370Kh/s per card. 5 HW Errors after 24 hours was acceptable. But this morning I woke up to a DEAD card, and I couldn't even restart the miner, it would just hang.

It's quite a shame, I really like VTC but I'm working full time during the day with no access to my mining box (company policy... can't use remote desktop etc)... and I need the thing to be reliable.

[utlord]

Guys, i need your help! i have got 3 machines and none of them can run intesnity above 12! i get tons of HW.

At first i thought that it was a  RAM problem, then i have added 4 more gigs for a total of 8 gigs, but it didnt help!

I have 280x,7950 and r9 290. None of them can run intensity above 12 with out HW.

I have tried adding setx commands etc.
Lowering Core, memory. Does not help.
Im using vertminer 0.5.3 also tried 0.5.2

Any ideas?



i would really love to mine this coin, but with intensity  12, i get around 200khs on each card
