Hey if you all use this but want a easier way of creating configs. I Have ported cgeasy to a site on my pool. Feel free to check it out at http://give-me-ltc.com/configs

DING we have a winner! 590 k/hash :-D

Now I'm going to try to get the 7870 up to par.

np.  good luck.

Payment sent.

No luck yet for the 7870.. Undecided anything equivelent or close to what worked on the 7950 seems to fall on its face.

Thanks!
Try these thread concurrency values with the same settings otherwise as for the 7950, but with aggressions between 13 and 20
13568, 14336. 16000, 16384, 17408, 18432

The concurrencies are really strange, for instance I have no explanation of why 8000 is optimal for a 7770

For 550kh/s+ on my 7950 I use this config:

Code:
host ???
port ???
user xxx
pass xxx


protocol litecoin

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 24576

edit: After playing with this for a while and plotting thread_concurries and kh/s quantities, I can say the following:
- For any given card there is a thread_concurrency value range which is optimum with lookup_gap == 2.  For the 7770, this span is 6080-11456.  Below this range the number of stales increases, with it becoming mostly stale in the 4000-ish range.  Above this range, the speed in kh/s drops dramatically.  Within this range, speed in kh/s seems to plateau and is nearly constant.
- Using the lowest thread_concurrency values seems to use the least power (I guess because less memory is being used).
- You can run 1550MHz+ RAM on these cards using MSI Afterburner with this file in the Afterburner folder and overlocking mode set to 2 in the Afterburner configuration.

I've been able to get 315 out of each of my 7870s (total of 630-640 in reaper).

On the 7950 (there is a 7870 in the same system as well, not sure if that matters) I have yet to get above 340, and that is in cgminer. Reaper it wont go above 310.

I'll try to keep playing with it hoping for a burst of better luck. but i'm running the ram at about 1350 on all the cards, so I doubt I have much more headroom there.

What is your LTC address? I'll send some coins your way for the help.

You should be able to get more kh/s mining ltc than you get mh/s mining btc.  As I said, a 6870 should pull 350kh/s+ easy. I get 550 kh/s on a 7950.  You do have to wait a little while for reaper to reach the correct reported hash rate too, it took me about 6 minutes before it stated 550 kh/s.

What driver and SDK version are you using? I'm using the latest on win 7.. and no matter what settings I try I can't seem to get above 300 on either of my cards on cgminer or reaper.

Bounty of 25 LTC to whoever can get me some proper hashrates on a 7870 or 7950 Smiley

in reaper.  7770 gives me ~190kh/s overclocked with same settings and gpu_thread_concurrency 8000 (64 * 125) with ccc 12.8 and app sdk 2.6

a 7870 has 2x the shaders as a 7770 so you should get ~380kh/s and my 7950 gets ~550kh/s

The trick must be finding the right thread concurrency for your card, which at this point almost seems random.  I would just multiply 64 by progressive numbers above 100 up to 256 and you'll probably find something that works the fastest.

aggression is 12 or 13?

I've tried both 12 and 13, but mainly have been running at 12.

I got this from some Russians, they use 64 * (memory bus size) for the gpu_thread_concurrency ...

I gave that a try and got 490-500 khash. This is with 1130mhz core/1200mhz memory on two 7870s and the computer is absolutely unusable (due to the high agression).

This is the config i typically use.. and I get 615 khash with it and the computer is perfectly responsive (with 99% gpu utilization).

Code:


worksize 256

cpu_mining_threads 0
threads_per_gpu 5

Right, sorry.  There's a bug with cgminer right now that I wasn't aware of because I'd been using a 7770.  For some reason thread-concurrency values above 8192 cause the program to crash, which is what is needed for you to achieve a solid hash rate on cards with more than 640SP that are 7xxx series.  Once this is fixed, the program should run better.

(If this is inappropriate for this thread mods are free to delete it or OP can let me know and I will modify as necessary)

After looking into this a bit further and trying multiple things out this is what I have found:

Reaper looks like the tool to use for 7000 series cards.

I could never get above about 130 khash on a 7870 with cgminer. With reaper, i am getting about 310.


The following three links helped me get the info I needed to properly set it up. I thought i'd share this with the rest of you guys so you dont have to search for it as well Smiley

Don't use reaper, it's much less stable than cgminer and slower on the 7xxx series to boot.

Use the following cgminer settings:
--scrypt -g 1 --shaders 1280 --thread-concurrency 16000 --worksize 256 -I 13

for the 7xxx series you should use -g 1 and --thread-concurrency of (12.5 * number of SPUs)

Intensities of 7-15 tend to work best, setting intensity too high gives horrible hash rates and all stales

Should be faster than reaper if not as fast.  With a 6870 you should be getting 360kh/s in cgminer (I get 180kh/s in cgminer easy with a 7770, which has half as many compute units).  Additionally cgminer seems to use less power.

Tried this for litecoin.. only was getting 6.7kh/s on my 7870's.. *unamused*

However, your bitcoin tool worked BEAUTIFULLY. I was never able to get cgminer to work correctly before on my own. What is your BTC address so i can send you a tip?


Yeah, 7xxx series GPUs are HORRIBLE for scrypt at the moment, I think there is some memory bottleneck, but I could be wrong.

Glad it worked!
