@CHRYSOPHYLAX--

DJM34, master of all things Vertcoin, suggests the following command lines:

ccminer.exe -a lyra2v2 -o stratum+tcp://pool.verters.com:3333 -u djm34t.user -p password  --api-bind 0  --cpu-priority 2

or, for 750ti:

ccminer.exe -a lyra2v2 -o stratum+tcp://pool.verters.com:3333 -u djm34t.user -p password  --api-bind 0  --cpu-priority 2 -d 750 -i 19

--scryptr

you guys are awesome ...

it will be for the 750ti cards ... its all i have in the nvidia side of the farm now ...

when the donation links go live - the devs should expect to see some donation mining happening from our end on their links shortly after ... cant wait to get back into the office to get them all active ...

is there any special settings for neoscrypt that needs to go in? ...

tanx much for the help once again scryptr ...

DONATION FOR GOOD WORK--

DJM34, Pallas, I flipped you each a nickle.  The overall improvement on both Lyra2v2, and on Neoscrypt, was excellent!!!

As soon as I can compile SP_ 's release dot 60 on Linux, he's up for his reward, too.  The teamwork and co-operation is really good for ccminer.  Everyone should donate....

Thanks!


--scryptr

That's why I started working on nvidia: there is community work. Once there was on AMD as well.
Thanks for the beers! :-)

Get lates on git.
It builds now.

Beers would be great

At the current difficulty 1 single 750ti will earn around $1.35 per 24h with the new vertcoin algorithm.

With 100 ti's. $135 profit for 1 day of mining!

quark @ nicehash is only paying $0,394968 a day per 750ti.

Vertcoin is 340% more profitable than quark...

Go get those coins, and donate some to the hard working developers..

Happy mining!

Beers have been sent to Sp, Pallas, djm34 both:))) . Thanks's for your co-operation, .About pools, i cannot connect to givemecoins,ffpool and nicehash pools, coinotron shows the half hash, vertminers the only pool i mining without any problems right now..

[pallas]

I've been mining on give me coins successfully for some hours, but only on nvidia: on amd it is mostly rejected shares.

I just tried with nvidia ,haven't been tried with amd's yet ).Give mecoins don't work on my side.changed ip and so on,strange ftc pool worked but vert pool don't wanna ) I sent a support request ,waitinig for an answer from pool..
@pallas what's the hashrate of 280x? And which miner for the new algo?

I didn't try the latest git commits of djm34 to see if they fix cards < 290 yet.
Hashrate should be 5-6 Mh/s.
I don't know of any other miner for lyra2rev2.

don't know either... (there is nothing "strange" in bmw256 except a few functions which were declared as static, which I removed, so I don't expect much change quite frankly... trying to fix something which works on my computer isn't easy...)

Hi all, was just trying sp 60 release with new VTC algo

I get a solid 4160 Khash/s on 750ti with config posted by scryptr, but on 970 its gyrating wildly from 9200 khash/s to 6900 khash/s with scryptr config. power & gpu usage is very choppy on both cards.



EDIT: 970 has now settled into nice hashrate between 8900-9200 khash/s, but power & gpu usage is still choppy as hell. will this affect durability/life of the card?

use my version https://github.com/djm34/ccminer-lyra/releases (which actually is the official release  )

(it is probably related to either work_time somehow or rejection of dup or stuff like that, sp/tpruvot tends to use some crazy stuff there...)

Are you talking about gpu usage as hashrate is now stable?

By looking at the graph it look's like the miner can be optimized.

You GPU will downclock if it goes over 70 degrees celcius.(trottle) I think this is what's happening here.. Is the hashrate stable in the first 100 accepts? (if the card is cold).


try to change the p-state in Nvidia inspector to p0.

I guess you are right about that but its stable now at 9100-9200 khash/s but gpu & power usage is still choppy. I will download & try nvidia inspector.

EDIT: Although i had no problems running other algos like scrypt-jane at 74-75 C and it wont throttle. I have seen that choppy usage come only with ccminer. on cudaminer i never have this problem.

70° for a 970 that's kinda low... (well my 980 are running usually around 70) 68°C with this algo for the 900 serie temp limit should be around nvidia limit (82°C even though I never saw my card going that high, except when I forgot to turn on msi and its fan custom setting).

However this pattern isn't associated with throttling which has no effect on gpu usage and just decreases clock speed to match tdp requirement.  This is clearly related to ccminer asking for new block header all the time... (check dup or crap like that... which isn't useful at all in most case)

this is how it should look like:

[sambiohazard]

Is v 1.9.7.3 latest version for nvidia inspector? Any links?

[sp_]

use the nvidia-smi.exe tool instead in the command line. Should come with the driver.

[sambiohazard]

I think djm34 is correct sp_ please check out what he is suggesting. Thanks djm34

750ti is so smooth and 970 throttles only because it is crossing my temp limit of 77 C.

Quoted from the NiceHash thread (with apologies by scryptr)--

Vertcoin is forking to a new mining algo, a modified lyra2re.
Will you add a new algo or replace the old one (or none of the two)?

Huh, these guys at Vertcoin are really fanatic with those algo forks ... we'll take a look at it and we'll probably add the new algo.

Has the new lyra2re algo been implemented on nicehash yet? I'm currently mining with the old one.

HARDFORK --

The old algo is mining on a bogus fork.  The new algo gets rejects on NiceHash.  People are paying for bogus hash.

We are in process of implementing the new algorithm Lyra2REv2, we have to implement a new validator and test to make sure everything works fine. We never rush on adding new algorithms before things are stabilized and tested. Of course, the original Lyra2RE algorithm will stay and there is nothing wrong with it - there are several other coins, besides Vertcoin, that are still using the original version of Lyra2RE. And to make clear - Lyra2RE algorithm hasn't forked, only Vertcoin (the coin itself) has forked to new algorithm Lyra2REv2.

Thank you for using our service and kind regards,
NiceHash team

THANK YOU FOR THE INFORMATION--

I apologize, I did not consider "Lyra2v2" as just another algorithm.  However, many miners are confused as to why they get nothing but rejects when attempting to mine with the latest VertCoin software.       --scryptr

NiceHash set me straight.       --scryptr

was looking yesterday at nicehash website, and it isn't clear what someone ordering lyra2re is mining (at least not from the outside...)...
