The big VTC Vertcoin settings thread

[Bionic345]

My cards seem to work fine now with those settings.

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
C:\VertcoinGPU\cgminer.exe --scrypt -o stratum+tcp://mine1.coinmine.pl:6350 -uxxxx -p xxxxx -o stratum+tcp://eu.bitcrush.info:3444 -u xxxx -p xxxx --lookup-gap 2 --thread-concurrency 8193 -g 1 -I 13 -w 256 --auto-fan --gpu-fan 30-85 --temp-cutoff 90 --temp-overheat 85 --temp-target 75 --gpu-memclock 1500 --gpu-engine 1020 --gpu-powertune -20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

3x Saphire R9 280x Dual-X, actually 4 but one it running on this pc till end of the week, so it does just 270 or so.

Only thing which makes me thinking is why GPU 2 is making so much less shares!?

[nastynate]

I've got similar problem with Gigabyte r9 280x.

I can't in any way get over 300 kH/s. Well it would be nice if it reached something about 350 kH/s ; )

My current settings:

Code:

-I 13 --thread-concurrency 8192 -g 1

Any ideas?

And also one thing is bothering me, why I can't set 2 gpu threads  (-g 2)?
It's impossible in any configuration : (

I think the gpu threads is probably your problem, but I don't know why you can't set -g 2.
I am running 4 Gigabyte R9 280X cards in one of my rigs on Xubuntu 13.10 and vertminer 0.5.3, gpu BIOS undervolt @ 1.094V. Still tinkering but these settings are what I'm using for now:

Code:

--scrypt-vert -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-engine=1025 --gpu-memclock=1500 --gpu-powertune=20

I tried your settings, thinking maybe the gpu-powertune=20 will help, but I'm still getting this error, if gpu-threads parameter is set to 2:

Code:

Error -4: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)

However in the meantime I reached stable 325 kH/s with these settings:

Code:

-I 19 -w 256 --thread-concurrency 8192 -g 1

Hey, thanks for the comment. I did not realize that I was running really hot when the ambient temperatures are very high!, btw, I am from Bangalore, India and probably one of the very few miners in India who has invested in Mining. (Well, pooled money for a long time to get a gaming system, and now it's serving a dual purpose and slowly paying for itself! with extremely high power tariffs!) Either way, with the high ambient temperature, it makes sense to run'em as cool as possible. After fiddling around with the settings some more and undervolting, the following are the temperatures. Might be useful for someone!

Now I've got a bit more hash with cooler temperatures! yay!

Alright nice, care to share your settings and configurations?

Best tip I can offer to anyone struggling with good settings is to try backing off on the engine clock. After setting up my R9 290 card to mine LTC, I switched to VTC and spent about a week struggling with instability and driver crashes (I could either mine at 200kH/s, or 300 for a few hours at most). With version 0.5.3 of vertminer, the fix for crash on quit made it a bit easier to tweak the settings, and I have had 400kH/s steady for a couple of days (less a couple of short breaks for gaming).
I was mining LTC at clocks of 1049/1450, and not great hash rate, but it seemed OK.
Settings:
"thread-concurrency" : "25600",
"gpu-engine" : "896",
"gpu-memclock" : "1498",
"intensity" : "18",

Temps 80* at 85% fan (20* ambient)

There seems to be something odd around I=13 for me, below I get 10s kH/s, the same as after the driver crashes. Also only a cold start seems reliable at getting the effect of new settings al the time.
The process was: Set I=16. Make some guesses for TC, find something that looks good. Adjust engine clock up/down in steps of 30MHz to find the best. Experiment with reducing mem clock, and small changes in value (ideally with also changes in engine clock to look for a peak). Finally push up I to the point when it stops improving (so being backed off a little from the point of generating too much heat, and being too sensitive to hardware errors).
A:605862 R:1142 HW:0

Edit: Just remembered after seeing a post on the main thread, I had a crash early on with VTC where the clocks seemed to get stuck too high (even after a cold boot which was the only way I could even get a stable desktop). Need to go in with a GPU tuner to set them back to near stock (mem clock ended up at 150 MHz once too)
Before my tweaking I was getting HW errors but overall I seemed to win from increasing intensity. All gone now though.

Had issues the first night i tried to mine it.

Worked good for 1-3 hours then CGwatcher went on a reboot loop of VertCoin miner.

Any idea why ?

hi im trying to add intensity flags to my gtx670 but it always instacrashes cmd

how do i add k7x32 to my bat file?

anyone?

[cryptoderf]

Anyone mine with a mac?

I tried to mine with cgminer CPU only all I got are rejected blocks.

A Few Questions:

I've been mining only a little over two weeks now, and I had been using GUIminer on scrypt mining with a 290x Tri from Sapphire and an old sapphire 6850.  I got my hashrates to the range scrypt sites recommened, but a strange thing was happening--my 6850 was making more shares than my 290x.  I'm assuming after further reading this was due to HW errors, but in GUIminer i can't see those. 

Enter me buying another 290x, removing the 6850, and setting everything accordingly in GUIminer (after replacing the cgminer it used for scrypt with the scrypt-N modded cgminer), my hashrates for my 290x cards were both sitting 462 each steadily.  I was happy with the hashing rates.  Last night was my first full night to let them run full speed.  The 290x which my monitors are plugged into, however, only put up about 70 shares the entire night, while the non-display 290x put up almost 700.  They were both hashing at 462kh/s.  both using the same settings: 970 core/1450mem OC.  I've got 12GB of memory on my rig so I don't believe it's the memory bottleneck many encounter, and I've got a 1000W powersupply, which for 2 290x cards should be fine. 

Is the only likely cuprit HW errors?
 thus i need to start using cgminer/cgwatcher directly so I can track that more easily?
in general, is more Khash/sec=more shares=more vertcoin?

[mrbrdo]

The only settings that work for me on R9 280X (various brands) are TC 8192 (and NOT 8193, = HW errors), gpu-engine 1000 or 1010, and powertune "20". This works for me both on undervolt and on stock voltage, both Asus and Sapphire cards.

I tried to mine with cgminer CPU only all I got are rejected blocks.

It's not worth the electricity to mine with a CPU. GPUs are much more efficient. If you think Vertcoin is going to rise in value, spend what you'd spend on electricity on an exchange instead, buying Vertcoin. This will benefit Vertcoin much more than any mining you could do.

What software are you using? How much khash/sec?

[cryptoderf]

Please guys post your software / OS you use for mining along with the parameters.

are there no nvidia users at all that can help me

Hello
I have several MSI R9 280X GAMING 3G (912-V277-057) that I am trying to setup here, with very little success.

I read the entire thread and tested all the configurations, not one of them worked with two threads ( -g 2 )
as soon as I enter -g 2 (or gpu-threads 2 in the config file) I get this error:

Error -5: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)
GPU 0 Failure, disabling!

I am testing only 1 GPU, windows 7 64 bit, driver 13.1, card is MSI R9 280X GAMING 3G, (soft is vertminer NR3 and cgminer AleksNR3 both is the same) also use setx GPU_MAX_ALLOC_PERCENT 200 doesn't change anything either.

my current settings:
"kernel" : "scrypt",
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"gpu-threads" : "2",
"Thread-concurrency" : "8192",
"gpu-engine" : "800-950",
"gpu-memclock" : "1250",
"gpu-powertune" : "0",
"gpu-vddc" : "1.100",
"scrypt" : true


The only way I can make it work is using 1 thread, TC is not important here, no matter what TC I put on it the result is the same (tried low as 500 and high as 27000).
Mining with -g 1 gives me 270 KH (at 950/1250mem), if I OC to 1070/1500, I get 285 which is useless.

I had 8GB of RAM, but decide to try 12 to see if there is any difference, nope, same results.
Tried other intensities but hash speed drops dead below 100, only i 13 gives me 270KH

any ideas?

Everyone seems to be asking questions but I just wanted to thanks to all the guru's who are providing answers and helping us. I read and re-read the info on here and I am happy to say I have 7 290x running at 463KH/s a piece, on a 8gb ram stick.

I will give out a little info to help other people regarding RAM. On this rig a friend tried adding up to 32gb of ram. He had the same results as running 8gb of RAM. What he did find out though is RAM speed made a big difference. Using 8gb of 1333mhz he was getting only lower 300KH/s. Once put in 8gb of RAM with 1866mhz he reached the current speed of 463KH/s per 290x.

So if you are upgrading your RAM (which I see quite a few people talking about in this thread) make sure you get a decent mhz. Hope this info helps someone out there.

[wintersondante]

tradeacoin, you're running 7 290x cards on only one rig? 

thanks for the tip on memory speed.  Willing to share the overclock settings you're running, as well as the ThreadC, Intensity settings, etc.?  I have 2 290x cards running 462-3 myself.  I'm enjoying comparing settings to see how people are achieving what they're achieving.  I'm also very close to setting up a farm with 40+ 290x cards with a couple friends, so the more data the better for me.

Thanks in advance!

This is most useful RL information. Thank you

GUYS.
I mine 4x290 and 1x7950.
I have important question. Look at image and my miner report about 1,900 khs but on site is only ~900 khs.
On Big pools (MPOS) i get even worst results! Speed is jumping like hell from 300-800 on p2p pools results are better.
And i can adjust difficulty.
Do you have the same results ? Almost all time Hashrate on dashboards have 1/2 -1/3  value compared to miner window?

Why it is happening?
Probably most people don't even notice that.
All are counting profit by straight getting numbers from cgminer WU parameter.
If you want use profit calculator you should give numbers from site it will be more accurate in this case you/me have counted 2x more than i should.

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
