Ugh, updates completed, but I can't get it to run. I'm thinking it MIGHT have something to do with not having a monitor plugged into it (forgot to bring my DVI-VGA adapter.

I'm running the following in a batch file

Code:

cgminer --scrypt -u [my username] -p [my pass] -o http://ltc.kattare.com:9332 --gpu-platform 0 -d 1 -w 256 -v 1 -I 18 -g 1 -l 1 -T  --thread-concurrency 8192

Returns error:

Linux was a complete fail for me. I kept getting kernel panics when booting after install of the 64bit Ubuntu 12.04, and I've had really limited time to play with it. My fuel pump went out on my car yesterday, so I spent the evening dealing with that. Anyway, I'm gonna give it a go on Windows XP (32bit), since I have an old box running that laying around here at work. I decided to bring in to work with me and play around with it while I work on other stuff.

It's got a plethora of updates to finish running before I can reboot to test it out, as it's been sitting for about a year, but I used SDK 2.5 and installed Catalyst 13.4.

Gonna try CGMiner with Litecoin. Will report back with results.

What SDK are you using?

If memory serves, 11.11 is the last driver that included 2.5, with 11.12 they switched to 2.6, and there were reports of lowered hash rates. I've used 11.11 on all of the 6xxx cards that I've setup, 13.4 on 7xxx, and the custom 7790 for those.

Edit: this is on Win7-64bit.

Works like a charm for BTC mining:

Getting the same numbers for Bitcoin. 11.11 drivers, cards report as 5800 series.

Engine 900 memory 1300 thread concurrency 8192 intensity 18

The rest of your bat looks good.

Edit.. I may be able to push more out of the card but I haven't had time and wanted to run for 24hrs.

Will also try bitcoin mining in a few days to see what speeds I can get.

I am getting 420khs. What settings you using?

The real question is what are your settings. Wink

Here is what I am using:

CGminer 3.1.0

--scrypt -u XXXXX -p XXXXXXXX -o stratum+tcp://us.wemineltc.com:80 --gpu-platform 0 -d 1 -w 256 -v 1 -I 20 -g 1 -l 1 -T --thread-concurrency 8000

Had the thread concurrency around 6144, but I get better kh/s with 8000.

Any help would be greatly appreciated.

Are you mining bitcoin? if so drop the memory down to 150 or 300.

I'm mining Litecoin.

And dont use shitty SDK. 2.5 or 2.1 (if possible). You will gain much mhash.

SDK 2.8

I played around with the core and mem and the best I am getting is 360 kh/s.
Oh well, still slightly better than my old Barts 6870s plus these have warranties. So still a win in my book.

Just wish I could get the full 400 kh/s out of these cards. :/

Hmmm. Damn. I'm getting only 360 after raising it to 950mhz and mem to 1200

Is 2.1 better than 2.5?

my first test card may be a freak but it is faster scrypt hashing (cgminer) with a lower engine clock. it likes 850 best so far.

after the diff increase and seeing it go up real quick, I'm having second thoughts if i event should build a farm. Am I the only one?

You should probably hold off for a week or so. By then, we will have seen if the LTC price has caught up to the difficulty or not. If it hasn't, it is only gonna get worse.

Sadly the more you hold off the more difficulty increases. I'm going to stop at 8 cards across 3 machines.

I am getting 420khs out the gate. Will work on tweaking later on.

Finally got them in my system. They show up as 6870s but have the Cypress processors and 1600 shaders. Can't seem to get mine above 320 without oc though.

Mind posting your config that you are getting 420 with?

You should be able to get 420 with 950mhz using all current version software. I would personally run a little slower depending on heat, I like to run undervolted and see how fast I can go at 1 volt. It makes less money but the hardware ages a lot slower.

thought about it, but the MOBO's CPU's are not returnable, so that's 450$ alone :S but nah.. I'll either return them or sell them to forum members.

I will probably be selling 14 of them and keep 4 for myself. Anyone in chicago area wants to buy them PM me. I dont feel like shipping.

Well if you bought 18 of em, you might as well assemble the rigs, mine for a month and then return them. You would be able to pay for the 20% restocking fee and more
