Topic: The big VTC Vertcoin settings thread - page 5. (Read 264278 times)

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?

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.

hi, anyone know for 6970? 

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.

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

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.

Just encase we want to organize this a tad .. similar to the Litecoin Hardware wikia.

setting for sapphire 290 tri-x please

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.

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


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 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.

nIcKeLbAcK: I have made some progress - thought I'd share it with you, see if it's any use to you. It's a bit clunky (but TBH I'm pretty busy with actual work in the real world, so made a kludge to get it working), but it works.

I'm now running 2 instances of vertminer.exe, one uses GPU0, and one uses GPU1.  What's weird is I did a bit more testing after yesterday, and found that on either GPU if I turned the other off, then it performed better, and that my GPU0 prefers threads set to 1, and GPU1 to 2.  So, rather than spending forever sorting out why (if that's even possible, I suspect there may be something that's beyond a settings issue), I did the following:

a) Copied Vertminer folder and renamed it (I now have vertminer-GPU0 and vertminer-GPU1).
b) Inserted the following line into vertminer.conf:
"device" : "0" (into the one for GPU0)
"device" : "1" (into the one for GPU1)
c) ran each instance individually (with a different miner username/login for each setup).

Both run OK, on one GPU only.  I now get ~160k out of GPU1, and ~120k out of GPU0.  No idea why, technically, but as I said, there are pragmatic limits, I'd rather be mining and doing stuff in the real world than spending 7 hours testing settings that will maybe net me £0.50 a day...

JohnnyDaMitch: When I get some time I will have a look at that; I definitely saw different behaviour with 0.5.2 in terms of quitting; 0.5.2 hung on exit almost every time I used it.  As you say, it's weird that I only see it in vertminer, but one thing I've learned is that software can do unforeseen things, and unless I want to spend days testing it, I guess I have to leave it at that.

nIcKeLbAcK and djaychela,

If your motherboard lets you restrict the PCI-e slots to Gen 2 maybe give that a shot. It's weird that you only see it in vertminer though. You could try the recent sgminer with nfactor support. Also, I seem to remember something about people seeing different behavior with vertminer 0.5.2 vs 0.5.3.

djaychela...

Thanks for the response. I attempted to run vertminer with GPU0 and various other scrypt miners simultaneously on GPU1, to no avail. I did receive an error that lead me down the path of using different api ports (GPU0-API 4028 and GPU1-API 5000) which didn't really work. Even with differing API ports the cards behaved weird, most notably with the fans competing for attention. It was as if the cards intermittently reported temps, the fans would alternate between running high then low, sporadically.  Unfortunately I will not be able to mine VertCoin as a result, unless I want to forego the use of one card for a measly 350Kh/s solely for VertCoin. sigh...
Guess I will dabble in CryptoMeth for a while

Hi,

I'm running the site http://www.crypto-coins-table.com.

I have listed your coin already. To provide the full information
for all users, everybody can update the information here:

Hey Folks:

Spoetnik:  The same values are used for both cards - certainly that's the case with cgminer (which I believe vertminer is a fork of), and bfg; both cards I have have run happily using one set of values applied to both.  From the cgminer 3.7.2 readme: "The setting passed to cgminer is used by all GPUs unless separate values are specified".

JohnnyDaMitch:  Thanks - I know what you mean about % / RPM, but given that the cards work OK in other miners, I had largely ignored the differing reporting of the same setting (although I do acknowledge that I could represent a deeper problem).

Aurum:  A worksize of 256 works well with cgminer, but 64 gives better results in my testing than 256 for vertminer - with 256, I get around 100Kh/s, but with 64 (which I saw someone else had used on a 7850) then I get around 160Kh/s; that's why I put it in there.  I've re-tested at 256 this morning, and got the same results as yesterday.  Thanks for the link to GPU-Z; I wasn't aware of it, but it has confirmed that my cards are running at the speed I anticipated (1050/1250) - I get this whether I specify it explicitly in the .conf file, or I use "0" (which I believe uses the system-set parameter) - either way, I get the settings I would expect (and that have proven very reliable long-term with cgminer and indeed bfgminer).

I tried the settings you gave, and got some interesting results - the hashrate for GPU1 (which is the good one) was around 110k (similar to the settings I've seen with worksize of 256, so I assume it's down to that), but GPU0 (which usually gives 6k) rose to 11k.  Using your original intensity of 13 leads to HW errors on GPU1 (as I found in all the testing I've done so far), so I put it back down, but at lest it shows that vertminer responds to individual settings.  A bit more testing showed that the 11k on GPU0 came from setting gpu-threads to 1; this slows down GPU1.  Setting gpu-threads to 2 gives a faster rate on GPU1, but slows GPU0 to 6k. 

nIcKeLbAcK: Looks like we're in the same boat then - again, I have GPU0 running at 6k, and GPU1 running as expected.  And as you say, this is the only miner I've experienced this with; I've run lots of versions of cgminer without issue, and usually use bfgminer now (as it works with MultiMiner), and neither has this issue.  

djaychela....
I am having the same problem with dual Sapphire HD 6970 cards. The vertminer applications shows that my memclock and engine are set correctly, yet one card only runs at approximately 6k while the other is running much higher, at it's expected rate. I have searched but been unable to locate a resolution. Have you come across anything? BTW I am using the exact same config file used for other coins with no issue. Vertminer is the only one with this problem. Even keccak runs fine with dual cards.

Appreciate help from anyone who may have suggestions.

All suggestions appreciated.

You're specifying a lot of stuff you do not need to, the card defaults are best, e.g. worksize. I don't have any 7850s but I'll bet the default is 256.  I'd simplify first. Here's my conf adjusted to your parameters. I think your problem is "gpu-memclock" : "0". If your PC drops to a slower state for one of your cards then cgminer will just leave it there. You need to specify a frequency or it can slow way down.
I use a utility called GPU-Z (http://www.techpowerup.com) that tells me the current clock frequencies and the card's defaults. I start by using the card defaults. TC should be either 4 or 5 times 1024 for a 7850. For lookup-gap and gpu-threads some cards like different combinations, try: 2 & 1, 2 & 2, and 3 & 1. Look here for some other ideas: https://litecoin.info/Mining_hardware_comparison[/code]

Without the comma it just uses the given values for all cards.

I've seen this before, where one card reports % fan speed and the other one RPMs. It's some kind of Catalyst problem that you need to sort out. Or possibly riser related. Probably you can swap the cards and see no change.

you don't have values for two cards in that conf you posted..
are you running both on one miner or are they using two miners or separate machines ?
see what i am saying ? look at what some of the other guys posted last few pages running multiple cards..
their conf's show two values with a comma delimiter added..
with values like this for example..
"intensity" : "12","13",
not just
"intensity" : "12",
