81  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] [LTC] [PPS] [OTP 2FA] [Stratum only] LTCMine PPS mining pool (2.5%) on: April 27, 2013, 07:59:01 PM
Gotcha! That's absolutely true about not running it on the same machine you are logging in with, but still i think it's better to ssh to my miner/server through lan and run it there, no way mobile is gonna be more secure(?) The miner/server is a headless *nix box that has only the ports needed for mining opened to internet. Grin

Actually it's more secure to use mobile application.
Why is this? In my experience at least mobile os are much more vulnerable to trojans and viruses as it is that their av development usually falls far behind even compared to windows. And I for one feel uncomfortable running anything that private on anything else than on a *nix platform at home.

Спасибо,
I was misguided by this post http://evadeflow.com/2011/09/desktop-authenticator-for-google-2fa/ , it seemed like google role there was just generating secret code for the phone/java app and developing android application Smiley. I have seen hardware time-based tokens, and how they work i believe you generate private/public key pair, embed public part in hardware token and use it together with system time to generate OTPs
Currently used implementation described by RFC 2289.

Working perfectly with jauth and without google account, much appreciated. And special thanks for pointing to the RFC. After reading it very pleased on the concept. Banking level security is wise when dealing with financial assets.

Has anyone gotten this working with stratum-mining or are all the stratum pools using litecoin-eloipool?

http://fcpool.com/ has stratum support.  Wink

1 x 7970 running about 645Mhash:

1125/1000

GPU 71 C
VRM1 94 C
VRM2 62 C

fan-speed 55%/2552rpm manual setting. Can drop the VRM to 88C with 60%. On auto fan, lets the VRM1 temp go to about 110C.



1 x 7870 running about 420Mhash:

1160/1200

GPU 69C
VRM 79C

fan is auto, running at 50%/2050rpm.

Whoa that's some hot memory. Have you ran VRM at such temps for how long and/or before with other cards? Somehow this made me think that BBQ Coin should have had temperature as a factor to diff. Grin

Might as well as my voltages to it as well as hash rate producing at the temp if you dont mind  Smiley

EDIT:
I don't like my cards hitting 80C so i try to keep it below that by opening windows or turning up the fans speed or what not.

I thought about adding those too on the questions, and now i'm gonna do it. As I was contemplating on it and the first person to answer came to the conclusion of adding them.
Nice figures you got there. Smiley

1. GPU model
->Radeon HD7850 (x2)
2. GPU/MEM clocks
->1100/1300 (stock 860/1200)
3. Avg. temperature
->83C
4. GPU fan speed
->~2000rpm
5. I have ran it mining as above for over 48 consecutive hours
->Yes
6. The highest temp i feel comfortable
->88C
7. Hashrate/algorithm
->370Kh/s/scrypt (per card)
8. Voltage
->1.21V


I imagine we coinheads have at least as many OCs and tweaks applied to our beloved GPUs as the more so serious gamers.  Grin

One thing that pops up frequently is the anxiety of how high temps can your GPU handle and what should be considered for safe limits to the chips. I for one am not comfortable if the temp exceeds 88C.
So i thought we might collect some info here and post our heat levels and possible OC's below.

If you wish to use the same format as you answer it would make it much more easier to browse the results itself, so if possible do so and put your comment under the stats.  Roll Eyes

PLEASE DO NOT SUBMIT TEMPERATURES AND FAN SPEEDS ON A MINER THAT HAS NOT BEEN MINING FOR AT LEAST 4 HOURS FIRST TO WARM UP.

Edit: Added hashrate and voltage to the questions. And if you wish to share your cooling setup, please do so in the commentary. Mine are stock-cooled and on a open rig with 2,5inch pcie-risers.

Hey guys.

Can someone please just copy and paste EXACTLY what they have for cgminer for get some nice khash/s with a 7850? I have a sapphire one getting 270-280 with no settings but -I 12. ( Higher than 12  gives less and HW errors)

Already did so on your previous post: https://bitcointalk.org/index.php?topic=182747.0

Just noticed that. Don't know if I want to run that hot. Shame, I can get 330 Mhash with ease.

It's always better to be stable and safe than to gain a few Kh/s momentarely. But you can safely take everything else from my examples and just adjust the clockspeeds and intensity down. Rest of the config works on 7850 with all clockings and intensities rather optimally. Smiley

I'm steady at 341.9Mh/s, so totally agree on the max of the card. I'm at 1200MHz core and 1300MHz memory. 1.18V stable

First off, were talking about scrypt here, so 341,9Kh/s would be more right. And secondly i'd like to point out that nobody has said anything about which card do they actually have. There are quite a lot of different cards with this gpu made by numerous manufacturers. In my case on scenario I have 2x XFX R7850 core edition cards with 1Gb of ddr5 running stable with cgminer @ gpu:1100 mem:1300 intensivity:17 1.21V
They produce 370Kh/s each with about 1% of garbage in rejected shares and hw-errors.

Hi, here is my recipe for running 370KH/s stable on XFX R7850 Core edition. Providing that you can keep the gpu under 86C, after that these start resulting in errors that exceeds the speed gain percentage. 85C and below my HW-errors and rejected shares put together are under 1%.

THESE CONFIGS INCLUDE OVERCLOCKS NOT SUITABLE FOR MOST CASED COMPUTERS DUE TO HEAT ISSUES (for stock clocks set gpu-engine to 860 and gpu-memclock to 1200 at cgminer.conf)

In your .bat file (that should be located in the same dir as cgminer.exe) you should have:

cgminer.bat
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe


And the cgminer.conf (also in the same dir) goes as follows:


cgminer.conf
Code:
{
"pools" : [
        {
                "url" : "stratum+tcp://pool1.com:8080",
                "user" : "worker",

        },
        {

                "user" : "worker",
                "pass" : "x"
        }
]
,

"scan-time" : "60",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

And a screenshot of two of those cards mining away with these confs:
https://i.imgur.com/bvbgsHW.jpg

That miner is on debian 6.0.7 but i have done the same with win7u. I'd recommend using ATI Catalyst 13.1 (haven't tried the brand new 13.4 yet) and AMD SDK 2.7 with that on both operating systems. And AMD ADL 5.0 if you build it from source code yourself. Cheesy

EDIT: Forgot to mention but maybe it's worth pointing out that after these steps cgminer should be started from the .bat-file instead of .exe. Hope this helped!

Ignore colour and flare and all the pretty bits that come later when refining the image - these are just design concepts for consideration as a basis for the final design:

Must say that out of all the design concept this satisfies my sense of style the most, maybe 'cause i don't like metallic colors that much in general.
Hope this refines to something else than the spectrum of silver/iron/gold.

Also not so fond of overuse of rounded corners on many of the other designs F-letters.
Even tho' these are also pretty curly... but it's a linear curl, not rounded off!
Maybe this is 'cause it reminds me how THEY round off my fiat money.
The EUR-spinoffs were also amusing for being so close to home, euro being my coin of choice when it comes to shopping necessities like toilet paper, cat food, coffee and cigs.
BTW/FYI even though we use euros in Finland we don't have the 1snt & 2snt coins in use at all, that gets me rounded up.
DISCLAMER: IMHO Roll Eyes

Not really sure what to think of this newborn, expect that I don't see it hurting anyone!
It seems kinda useless or extremely oversighted in my mind at the moment.
But this is the mantra we have been hearing over every new cryptocoin.
I for one am prone to dreaming that LTC would become the 10pence of BTC's one pound.
And as for now i see no need for a 5 pence coin I don't percieve it being impossible that it might come mighty handy some day, but only time will show.
Also as much as I love scrypt, I would have liked to see a change in algorithm just for the ease of paranoia over many coins falling over one vulnerability.

But overall really interesting to see what'll it be growing into... or what could be it's doom. And it felt kinda great to be solo mining with less than 1MH/s(scrypt) / 1GH/s(sha256). Got lucky too! 720KH/s has given me 3 blocks over the last 24 hours before this post (diff atm: 23.88328949) and the expected time at my rate for one block ~40h. Grin
Well guess it's back to LTC on full steam... or is it... maybe i'll have to wait for 24 blockless hours on feathercoin first. Lady luck might get offended. Cheesy

A PLEASURE!

Nice view to the loads. It really feels good to see that your server has that much "breathing space".

And I also second on the admiration of the transparency of this pool op and how well the user interaction works. Top-notch user experience!
Wish i got something like this for the services i'm actually paying for, even my ISP makes me hang on the phone listening to their 30sec waitin jingle for hours at best when trying to get tech support. And the tech-knowledge level of those call center geniuses is usually something... well let's say a little less than satisfactory. Donations away! Cool

Hm... It seems that I was wrong. Our DNS provider http://nichost.ru also unavailable now.

Possible workaround is adding

Code:
91.235.143.14 ltcmine.ru

to hosts file.

In my case this ip-address leads to Abe Search that lists novacoin blocks, but it ain't the weirdest thing I've encountered with updating dns-servers Cheesy
Hope they get 'em fixed soon.

First off I'd like to point out that so far your pool has been somewhat superior by far to my taste. The web design on the layout alone would deserve some sort of prize. I seriously love it. The site has everything you need, simply where you need it and that's how i think information should be presented on the internet. And the emphasis and precautions on security, gotta love it. Many other pools didn't even know what had happened when ltcmine was already long on the case!

I really hope it does not come to the point of having a google account mandatory.. on your pool.. or in life in general. Sad
I already gave up on my youtube-rights to avoid getting one. And I know I'm not the only one.
But whatever happens I still would like to thank for the quality ride, even if i'd have to get off on the next stop.

Set thread concurrency to 9984, gpu: 1100MHz mem: 1200MHz I:17-18 if it's a dedicated miner.
Remember to disable windows aero etc. If you're using it at the same time, even to open the start menu then lower the intensity. Cheesy

I get little over 360KH/s with 1% of garbage in HW: & R: per 7850.
A few more KH/s in debian squeeze 6.0.7-amd64 with self built cgminer 2.11.4.
On another partition i tried it with win7u 64x with the prebuilt cgminer 2.11.4.
On both OS I used Catalyst 13.1, AMD APP SDK 2.7 and ADL SDK 5.0 ...obviously the adl in windows was whatever version it was because it came in the prebuilt cgminer.

I't also runs for a while at +390KH/s at gpu: 1200MHz and mem: 1300Mhz
...but wouldn't recommend without liquid cooling. And what ever you trial i'd say leave the voltage lock untouched. Tongue
