heh
getting
607khash and 477kahsh from 2 x 7970
be nice if both were 607 Tongue

Try decreasing the values, like this:
--thread-concurrency 2048 -g 1 -I 11
and see what happens

Getting 173 khash/s now with --thread-concurrency 4200. Still lower than Reaper, but maybe more thread-concurrency tweaking will give extra juice.
UPD: 180 khash/s with --lookup-gap 2 --thread-concurrency 3500 -g 1 -I 17. Looks like thats a maximum.

Getting 30 khash (--scrypt --lookup-gap 2 --thread-concurrency 6144 -g 2 -I 17) with latest version comparing to 190 kh/s with Reaper on 6770. Pool showing same 30 kh/s. Maybe drivers/sdk fault? Using 12.1/2.6.

Change -g 2 to -g 1.

Nothing changed.
Can't get it even to work with another rig (5770 & 6870). Getting clkernel error.

never got over 292khash on single card, never got 4 card rig to run on reaper

decided to go back to -I 16 lose some hashes but rejects under 1% is where its at imo Tongue

on my 6950s is getting 449Khash /card across 4 card rig A:582 R:23 is a bit high tho might try -I 17

and 450Khash on single card A:169 R:2 is ok tho

I'm rather pleased with this Cheesy

how much did reaper do?

Changed my 6850s core to 800 and now its pulling 220kh/s. Saddly I had to go leave so I left it at that. I'm gonna see how far I can go when I get back, that's already more then what I got with reaper at only a 50mhz overclock.

Sorry typos on my phone

ckolivas, could you also set a user-definable parameter to adjust the difficulty needed for submitting a share?

Instead of reading off the difficulty from the pool? I guess so... but not right now.

Oh, sorry, I didn't realize that each pool sends its difficulty requirement to the miner. Just when I was mining with P2Pool (Bitcoin), it would send difficulty 1 shares to my local P2Pool node even though the P2Pool share difficulty is much higher.

Holy shit my 6850 pulled 207kh/s without an overclock with just intensity 14. I'll add a document with my settings for my 6850 and 5770 in a few.

Also catalyst 12.6 & sdk 2.6 are working fine for me now, weird but I'll take it.

I tried concurrency 3200 and 6144(better), any others I should try?

after a bit of messing round 427Khash/card over 4 x 6950s A:367 R:1

I am getting 369 average on 5870 (only one card in system) with clock 850/1200 on Windows 7, 64 bit, aero enabled.

Code:

cgminer.exe --scrypt --worksize 256 --lookup-gap 2 --thread-concurrency 6144 -g 1 -I 16 --url
http://notroll.in:6332 --userpass xxx:xxxx

with accepted = 150+ & Rejected= 0

with the new, i have set the -I to 16, and i get 210, with almost 0 stales, reaper could get 210 MAX, with 10% stales, this is soo goood!

Yup, increase in intensity certainly helped. Now at 338 at 16 and 340 at 17. At 18, kh/s jumps around a lot.

Time is averaged over 5 seconds, and at those high intensities the threads wont report in for over 5 seconds potentially so you'll get serious aliasing artefacts.

yah thats weird if i set mine to 14 it gets tons of rejects what card and settings were you using??

i use 2*6770, but only testing on 1, i use

Code:

cgminer --scrypt -o http://****:**** -u ** -p ** --worksize 256 --lookup-gap 2 --thread-concurrency 6144 -I 14 -g 1

and O/C is set to 950/1300

ok, getting 10+ kh/s more with worksize 128 instead of 256

worksize 64 doesn't seem to increase speed under any combo, so thats a no go. Must.... tinker.... MOAWR.

It should also note that I'm basing my speeds off AVG after about 20 seconds. I'm just trying to get the settings into a close ballpark before I do long term stability.

i have just trying worksize 64, and i got more speed now

worksize 256: ~180 kh/s
worksize 128: ~190 kh/s
worksize 64: ~192.5 kh/s

with the new, i have set the -I to 16, and i get 210, with almost 0 stales, reaper could get 210 MAX, with 10% stales, this is soo goood!

Includes commit g1711b4e, allowing up to intensity 20. There was another commit, but I'll rebuild it when enough has been changed.
