Topic: The big VTC Vertcoin settings thread - page 25. (Read 264260 times)

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.

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.

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?

Anyone mine with a mac?

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

anyone?

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 ?

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.

Alright nice, care to share your settings and configurations?

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:


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

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:

My cards seem to work fine now with those settings.



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!?

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

how do i add k7x32 to my bat file?

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:


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 have (3) MSI R9 280x, getting about 350k each. Similar settings to yours, except my (TC) is 8193 and (E) on 2 cards is 1030,
and for some reason my other card is happiest at (E) 1010

It blocked my image, but I'm getting 2-3 kHash.  I get 300 kH with normal scrypt.

Note the extremely low speed.  I've tried many variations of threads, gaps, work and intensity.  The tc worked great on normal scrypt mining, but I've tried alternate values of that as well.

I really wonder how all R9 280x users can use a thread-concurrency of 8192 and above. If I use something between 8000-8200 my hashrate is down to 15kh and I can't use my pc anymore. If I use any other thread concurrency I will get HW errors. I get most accepts with 6500 but HW errors still fly high ... ideas are welcome, I have tried several configs now btw. Currently play around with


Ok I reject what I just wrote, 8193 seems to work now !

^ this. Counting for inevitable/unavoidable losses due to computer/pool downtime etc you'd earn a little over a vertcoin per month - and that's assuming difficulty doesn't go up.

That website is asking for kilohash, you are entering 1000x less

CPU mining shows "hashespersec" : 5031,..." as reported by "getmininginfo" within the Vertcoin wallet.

This 5031 means the hashrate.

Using this calculator: [http://www.verters.com/vertcoin-mining-calculator] and entering that rate computes about 41 VTC per day. That is worth about $145 (per day) which is $4,350 (per month).  Where is my mistake in my calculation?

And I'm not even using GPU mining.

I'm currently looking at 170,000 hashes per sec on a $150 GPU. CPU mining doesn't make sense for Vertcoin.

Pretty sure I've read that iMacs are unsuitable for mining. They look nice but don't have proper cooling.

According to the numbers the 6970 gets for Litecoin you could expect ~200KH/s for Vertcoin, maybe a little more. Should net you a coin and a half a day at current difficulty.
