try using an older version of GUIMiner, I was having the same problems and switched to 2012-02-19 and so far so good.

finally got it stable!

I went back and used an older version of GUIMiner and it has been running strong. Average while watching deepbit has been all over the place from 590-675MH/s

now to move on and experiment with different driver & SDK versions, clock speeds, flags etc.

I may try on another connection tomorrow (I have several available at work, good to be the sys admin) and see if that helps.

I have been trying to see if deepbit needed some special config I needed to put in my router / firewall but haven't seen anything yet.

So like many I am kicking myself in the ass for not starting this a few years ago like I had planned....so I finally said screw it, setup a box at work running a single 7850 1GB card.

setup and secured my wallet, backed it all up, protected it

Installed GUIMiner, joined a pool (deepbit for now) and started mucking around to get used to it all.

For the first two days I continually had connection problems while mining at random times. finally it ran all weekend with no issues, then monday it started with the connection issues again off and on every few hours.

today I got hold of a second 7850 to put in and add to my miner.... but still I continue to run in to connection problems (as indicated by GUIminer)

I tried everything at stock first then ran the GPU at 1010MHz with the following flags -v -w128 -f1, fail off and on then again all weekend was fine then problems again. (average was only around 300MH/s though)

I have tried a few different flags and still haven't had luck and it seems like I should be able to get more than 600MH/s with my setup.

What can I look at in particular to eliminate the connection problems? Is this a pool issue, GPU issue, network issue?


eventually as I get the basics down I am going to order some of the ASIC devices but want to get this down before I make any other investments

Any help is appreciated!

(side note I am looking in to linux based distros now for my miner, I just want this to be a set it and forget it system lol)

Paladine: I'm using a 7850 (just recently got a second) and on average the best I can seem to hit is about 300MH/z average @ 1,010 MHz core with peaks up to 350MH/s (the nvidia card you have wont get much better sadly) so that may give you some sort of average to look at where you should be.

This is on windows 7 x64 using GUI Miner -v 1 -w 256 -f 1 (I tried w 128 and f 0 as well)

right now I keep having my miner say connection problems, you wouldn't happen to be having that issue as well would you?




Garbaek: I may look in to that myself thanks

I thought GPU was the only way to go right now for litecoin? FPGA and ASIC were not available or used in mining?
