Title: Just started first Rig LTC,(changed) Help hash rate tweaking please SOLVED Post by: Protagonus on April 16, 2013, 12:28:42 AM Hi, sorry ahead of time for the dumb questions. Here's where I am at.
Rig built, signed up for Pool (coinotron) made worker. CGeasy - to create config (no OC) CGminer running- (showing 470kh/s appx) So, I show connected to coinotron and to my worker. I show a hash rate and several "detected new blocks" Also there is one "best share" where it shows in notes "accepted XXXXXXXX Diff XXX/XXX GPU 0 Next, I log into coinotron website to see what it's showing there for the worker. Now is my question. Coinotron shows my worker at 0kh/s and no mining ever done? How can I be connected to coinotron and my worker and have a best share with 0kh/s on the website? Am I in fact mining correctly or do I still need something else? Any help would be great, as I'm sure I'll have more; but trying to get what I can. Thanks, Prot EDIT: the website now shows me at 14kh/s ???? This seems more of a mystery now lol. I DO note my connection has shown "interrupted" a couple times.

Seems REALLY low if it's bitcoin ;D Title: Re: Just started first Rig, How do I know it's working CG 470kh/s - Pool 14kh/s? Post by: Protagonus on April 16, 2013, 12:42:01 AM OMW sorry, LTC. Also, if it helps I'm running no flags atm. Just trying my first run to see how it goes. (GPU 7950) Only lowered Vcc a bit so far.
If there's other info I can / need to provide please let me know. Title: Re: Just started first Rig LTC, How do I know it's working CG 470kh/s -Pool 14kh/s? Post by: Protagonus on April 16, 2013, 01:39:07 AM EDIT: okay running it more I see a pattern some.
discovered new block connection interrupted reset connection connection interrupted reset connection discovered new block Etc. sometimes I will get 3 blocks before a reset. I notice also it says connected with Stratum at the top, not sure if that's the way I want to connect or not. (EDIT NVM stratum I see coinotron is only stratum atm.) Other items that may help Windows 7 64bit MSI 990FXA-GD80 Powercooler 7950 Other notes. I see in afterburner that when it seems to be working I get spikes 60-100% activity on gpu. When I see interrupt the activity goes to 0 for a second. I notice also that the RAM usage on the card is 230mb? Should the miner be using ram here, as I thought LTC used memory more. If anyone has thoughts I'd appreciate it very much. I want to get the "feel" and make sure it's working before I tweak for performance and such. Title: Re: Just started first Rig LTC, How do I know it's working CG 470kh/s -Pool 14kh/s? Post by: Protagonus on April 16, 2013, 02:52:21 AM Ok think I've gotten a bit farther. I would really love if someone could help, or point me to an area for help. It would be the first time anyone has helped so far.
One error, I did NOT have SDK. I read over the notes and FAQ for cgminer and the consolidated litecoin guide. So I have 13.1 Driver and SDK 2.6 I also set the recommended thread concurrency from the consolidated guide @ 21712 Upon starting this time I note NOW I'm getting all accepted and no rejects!!! YAY. However I'm showing only 240Kh/s average now. I will remove the thread concurrency flag to see if just the SDK dropped this. I didn't expect it to be half the speed lol. other CGminer notes that may help: Output Line; 240Kh/5s and 240Kh/s right now A:25 R:1 HW:0 U:2.4 read something somewhere about UW: but forget (think supposed to be .9/Kh/s) but UW: 306/m So now I appear to be mining correctly, but Speed is in the toilet 240Kh/s (not checked the site's report of my speed yet) NOTE: I DO have RAM usage now as well. I was NOT using GPU ram on first tests. Now it shows 1394mb. I have more ram on the card, how do I increase this? Any tips or help would be greatly appreciated. EDIT: removing the thread concurrency flag changed very little. the U: down .6 and the UW: down 50 (so 1.9 and 250/m) otherwise same kh/s. So, SDK cut the kh/s in half Title: Re: Just started first Rig LTC,(changed) Help with hash rate tweaking please Post by: Protagonus on April 16, 2013, 05:28:59 AM Further update I guess.
I played around with clock settings and concurrency and seemed to only change the Kh/s 50 or so no matter what I did. (so, 240-280 Kh/s) I know this is about half what these cards are supposed to get. So not sure what I have wrong at this point. Why do I only get 250kh/s on a 7950 card. Also, I tried Reaper, as some suggested that was better. However I cannot figure out how to get connected to coinotron; since their getway is closed. When I run reaper I get "error with server: stratum" . I know CG miner automatically connected as stratum and on the old port 8322. Any clues on how I can get reaper to connect then as well? Someone? Anyone? pleeeeaaasse? EDIT: in trying to find out how I can get Reaper to use stratum I was lead to GUIminer scrypt alpha; but alas, that's not available for download in this country. Help is needed with 2 main things 1. How can I get reaper connected to stratum with coinotron (error with server: stratum) 2. IF CGminer is the only program I can use, as it seems; how can I improve hash rates over 250kh/s Title: Re: Just started first Rig LTC,(changed) Help with hash rate tweaking please Post by: Benny1985 on April 16, 2013, 01:48:55 PM I don't know if Reaper even supports Stratum.
Title: Re: Just started first Rig LTC,(changed) Help with hash rate tweaking please Post by: Protagonus on April 16, 2013, 03:46:26 PM Ye Benny1985; the only way I found was to use GUIMininer Scrypt Alpha (or well that was suggested on a thread I read) but I have not found a site with that available.
Guess an update as well. I stayed up very late, as I couldn't let myself sleep without figuring Something out. Anyway; I have added the 2nd of 3 GPU's that will be in this, when done. So, I have 2x7950. After a lot of work, reading, adjustment; -I've gotten up to 470 Kh per card, showing an average of 970 Kh/s for the pair. -Cards were OC'ed to 1085 Core and 1600 Mem; with Vcc 1.143. -Running for the time I slept as a burn in @ I:17; I have a reject percentage of 4.2% (bout right from what I've read) -Pool website is showing incoming accepted hash from me at 900kh/s, so close to what the terminal CG shows. So, I guess I figured it out on my own here; wanted to update at least. EDIT: My final post on this as I'm pretty satisfied now. I do not want to bump thread again, so I'll edit. Final settings: -505-510 Kh/s per card on CGminer showing average of 1.05 - 1.1 Mh/s -Pool Website shows worker doing 1.118 Mh/s (so 559 Kh/s each) -Card OC is: 1065 Mhz Core / 1250 Mem / 1.093v / 69C -Intensity = 20 - 24hr stable Appx. 4% rejection Can't expect anymore outta these! I'm very happy |
