The big VTC Vertcoin settings thread

[dotnetmin]

Is it normal if at the moment i use another programm in windows while mining with vertminer hashrate goes heavily down ?


If i open a wallet for example, hashrate drops down to 15% of total. It takes minimum one minute to come back again and does
not reach 100 % of old value.

I tryed to mine DRK with sgminer and it doens`t make any difference in hashrate if i use other programms or not.

Hi Guys,

 i am new on vertcoin mining.


I am testing with my Gigabyte 7950 3GB with sgminer 4.1.1

Here are my settings

Code:

{
"pools" : [

        {
                "url" : "stratum+tcp://80.237.233.8:3333",
                "user" : "XXX",
                "pass" : "XXX"
        },
],
"api-listen" : true,
"api-allow": "W:127.0.0.1",
"nfactor"	: "11",
"worksize" : "256",
"thread-concurrency" : "8100",
"xintensity" : "4",
"lookup-gap" : "2",
"gpu-fan" : "60",
"temp-cutoff" : "85",
"temp-overheat" : "75",
"temp-target" : "70",

"gpu-engine" : "1050",
"expiry" : "1",
"scan-time" : "1",
"queue" : "0",
"kernel" : "psw"
}

I am using a patched version von SMOS. (http://www.smos-linux.org/)

For testing i have installed a Vertcoin mining pool.

It would be nice if anyone can help me testing my pool setup. With a hashrate of only one or two cards it will take a long time to find a block ;-)

Pool Frontend IP: http://80.237.233.8 or http://vertcoin.german-servers.de

Thanks a lot and greetings from Cologne

is it normal that WU less than kh/s on 290 non x? I got 420 kh/s and WU 319 m/s.

is it normal that WU less than kh/s  on 270x? I got 186 kh/s and WU 140-150 m/s.

WU should be about 90% of hash rate, just like regular Scrypt. But remember it takes many hours for the WU to stabilize. In the beginning, it will change significant amounts though it does it slowly.

not reach 100 % of old value.

I tryed to mine DRK with sgminer and it doens`t make any difference in hashrate if i use other programms or not.

yeah that is normal.. vertminer cgminer etc all require a bit of cpu power available at all times to work mining..
so if you all a of a sudden max out your cpu you should see a drop in hash rate until you free up the cpu again.
the cpu has to orchestrate the work like a conductor standing in front of a band.. he is not doing much but if you screw with him the band goes to hell lol
like the cpu is what is feeding the work to the gpu so if it has any delay in sending work then work speed slows down. make sense ?

i use vertminer myself with 1 gpu.. a Powercolor 7950 and i occasionally mine with my cpu on and off too or do video encoding etc
and i have different computers with different cpu's and it doesn't matter which one i use they all follow the same rules or problems etc.
my main machine is an i7 with 4 cores and 8 threads so if i use the cpu i make sure to leave 2 threads free for the GPU miner.
(so i would run the cpu vertminer with 6 threads via commandline) while gpu mining at the same time.

On another computer i have.. an nvidia card mining VTC with cudaminer with a Core 2 Duo e7500 and that is only 2 cores / 2 threads
and if use up the the cores on that cpu it slows my nvidia miner down too. I rarely ever cpu mine on that one because
it's not worth slowing down the faster nvidia gpu miner.. so yeah it's normal

Thanks for your detailed answer. I have noticed that the wallets only use much CPU power while they are not synched. After the are synched
and still open and stay synched it does not effect my mining power.

hi, anyone know for 6970? 

[PeaMine]

I know it's tiny, but what settings should I use for a GTX 260?
--algo=scrypt:2048 -i 0 -H 1 -C 0 -m 1 -b 4096 -L 1
Boosted me up to 4KH, from the default 0.22KH I was getting, so I know there is a lot of room for improvement.
Default clocks currently.

[Ed4252]

I have a radeon HD6850 and I'm only getting around 11 khash for my gpu while normally I get 170 khash running litecoin with intensity 13.

What could be wrong with my vertcoin settings?

[nIcKeLbAcK]

djaychela: Finally figured it out. Ok, Using the following conf file in conjunction with VertiKev https://bitcointalk.org/index.php?topic=466867.0  .......  I have found success. My dual HD6970's are pushing 420kh/s. Now, I launch w RI of 10240, but push it to 20480. GPU0 69C and GPU1 74C (this card always runs hot, dam XFX crap. Hope this helps. The key was ThreadConcurrency. Halve your normal TC, delete shaders. If you need shaders in then match it to your TC +or- 1
Hope this helps.
...and remember to delete your *.bin file(s) before launching the new *.bat or conf file.....cheers

Ed4252    TC is probably the issue you are having as well. So halve it.

nIcKeLbAcK: Top man!  Downloaded it, tweaked settings for 5 minutes and already got the performance I had with the two separate runners, but with one card slightly above, one slightly below (130 each vs 110, 150).  Will tweak more later, just going to let it run and see if it's happy.  The Raw Intensity setting seems to be a useful thing - I had no idea until reading that thread of the exponential increase that Intensity led to, no wonder I:12 was fine and I:13 was instant HW failure runs!  THanks again.

[nIcKeLbAcK]

djaychela:  Awesome! Anytime man. I mined 3.7VTC in about 9 hours...

[CybeRoky]

What is the maximum Kh/s for 7870?

I have three on my rig and I get:
185 Kh/s VTC

on LTC, DOGE I get around 405 Kh/s.

I read that someone get around 200? But I don't believed because I tried everything

[Anonymous2412]

Hi!

I have a couple of questions.
I won't be doing any serious mining right now, I just want to learn how things work before I buy a more powerfull computer.
I mine with my laptop, which has a Nvidia 750m (and integrated Intel graphic chip).
When I start vertminer it automatically chooses my crappy intel chip and not my Nvidia card, can I somehow fix this? Shouldn't it recognize and automatically use my Nvidia card?
Or should I use Cudaminer? I can mine vertcoin at about 44 Kh/s with Cudaminer (as I said, crappy card), but I'm wondering if Vertminer is more optimised or better?

I've heard people saying that you need lots of RAM, but Cudaminer only uses about 30MB ram when mining Vertcoin, how is this possible?

And also, how much can you "tweak" your program/miner for more performance?
This is my complete .bat, which I just double click to start mine:

"cudaminer -o stratum+tcp://eu.bitcrush.info:3444 -u xxx.xxx -p xxx --algo=scrypt:2048"


As I said, I'm completely new to this, but want to learn how to do it correctly so to speak

Oh yeah wallets are notorious at sapping CPU power maxing it out (until they are synced)
It's normal and some are way worse than others depending on the coin.. some people may not know that.

Still mining away using cgwatcher and Vertminer 0.5.2

Here is my whole bat file i use for my Powercolor 7950 in case people want to see it ?
Notice work size 256 ? i think the miner is hard coded at that value so if you try 512 or 128 it won't work..
You can see this by looking at the *.bin file name.. maybe some other miner version can let you change that i don't know.
And the second pool i have listed is a fall back if the main one goes down and that is pointed at my VTC wallet with a conf i made for the wallet for solo mining.
obviously i would have to have the wallet on and synced at all times to do solo mining with Vertminer though (if the main pool goes down)
Also notice a key setting to experiment with here is GPU Threads

Also here is the contents of my bat file showing how to specify a .Conf config file..
I have no idea if i used the GPU map feature correctly though, i want to skip my integrated Intel 4770k Haswell graphics chip and only mine with my Radeon.
Note: you do not have to specify the full path like below.. cgwatcher changed my bat file and did that.

Code:

is it normal that WU less than kh/s  on 270x? I got 186 kh/s and WU 140-150 m/s.

Try reduce the Intensity?  I guess your 290 non X is -I 21.  Try -I 20.

Try reduce the Intensity?  I guess your 290 non X is -I 21.  Try -I 20.

the typical and classic max is 18 some *newer cgminer mod versions use a RAW method combined with a max of 13.
so i don't think 20 or 21 or higher would be valid and it would default to some other value.. i'm guessing

for example vertminer 0.5.2 max is 18
for example vertminer 0.5.3 max is 13

edit:
i read the readme and i guess i'm wrong on that 20 may be the old maximum not 18.. oops

this is from the SCRYPT_README file..

--intensity XX (-I XX)

Just like in bitcoin mining, scrypt mining takes an intensity, however the
scale goes from 0 to 20 to mimic the "Aggression" used in mtrlt's reaper. The
reason this is crucial is that too high an intensity can actually be
disastrous with scrypt because it CAN run out of ram. High intensities
start writing over the same ram and it is highly dependent on the GPU, but they
can start actually DECREASING your hashrate, or even worse, start producing
garbage with HW errors skyrocketing. Note that if you do NOT specify an
intensity, cgminer uses dynamic mode which is designed to minimise the harm
to a running desktop and performance WILL be poor. The lower limit to intensity
with scrypt is usually 8 and cgminer will prevent it going too low.
SUMMARY: Setting this for reasonable hashrates is mandatory.

[phzi]

the typical and classic max is 18 some *newer cgminer mod versions use a RAW method combined with a max of 13.
so i don't think 20 or 21 or higher would be valid and it would default to some other value.. i'm guessing

<snip>

20 was the old max in cgminer.  Up to 23 is valid in the newer branches of cgminer such as sgminer.  And any scrypt or nscrypt miner worth his salt should be using sgminer or some other maintained branch by now.

Classic intensity values (when you aren't using RawIntensity or shader-based XIntensity) launch 2^I threads. e.g.
I:13 = 8192 threads
I:14 = 16384 threads
I:15 = 32768 threads
I:16 = 65536 threads
I:17 = 131072 threads
I:18 = 262144 threads
I:19 = 524288 threads
I:20 = 1048576 threads
I:21 = 2,097,152 threads
I:22 = 4,194,304 threads
I:23 = 8,388,608 threads

As you can see, the number of threads increases exponentially with higher values on I.  This is why using Xintensity for tuning is so much more effective.  Not to mention these values rarely match up with the number of shaders on the card, and the optimal number of threads to launch is a multiple of the number of shaders on the card.  This is why I=13 is the most effective on many devices - because they have 8192/N shaders.

The sgminer git tree even has pool-specific algorithm/nfactor support, and preliminary kernel hotswapping!
