Why I've got only 7 Khash (!) on 7850 card? I thought it wasn\t that bad...

Bufius are you aware if the cpu cgminer gives better performance than wallet mining? Just an academic question really at this difficulty, but interested to know
January 13, 2014, 01:58:32 PM
What intensity are you running too?

But 290kh for a 280x is too less, it should be ~350kh (i get ~300kh per 7950 @1000/1500).
Have you mined scrypt before? If yes, try to use the same settings, just lower TC.

Yeah I agree - 290kh sounded kind of low to me too. Memclock is the key, and core makes a big difference on the R9 series too.

Ok, so I got soloing finally set up on both my rigs. What a pain in the ass 
I'm running 280x's and get about 260kh. Someone said they had a 290 and got 400 ? So that seems about right.
But my question is It says connected to 127.0.0.1 without LP as user blahblah.
What does without LP mean? Does it sound like it got it setup right? Now hardware errors.

LP = Long Poll
For mining solo this is OK.
Check cgminer (first press "d" for Display, then "v" for verbose, then return/enter).
Now you should see messages like "Share above target" -> you are ming solo and everything works like expected.
If you see something like "found Block for Pool!" -> congratulations, you've found a Block
But i would prefer to mine into a Pool, the income is more steady. But of course, at the current diff with a 280x, solo is also getting good results.

No problem saying without long-poll, that's normal for solomining, but I think you'll be hard pushed to mine much solo now.
If you're getting hardware errors though, your thread-concurrency is probably too high. I am at 24550 on R9 290s, Bufius said 256n works well so you could try starting at something low like 8192 and working your way up, if 16386 works, start going up in smaller chunks. I also find I can't run such high core/mem clocks on this coin, maybe the algorythm is harder on the GPUs, but I have to drop down a little.

What happened to the bitcrush pool? I still had ~100 VRT on there 
It seems the pool really crushed My VRTs also stuck there.This sucks. Does anyone know who the bitcrush admin is?
stratum still works, so probably just site overload, but to be sure move to another pool (not the biggest one)

I also want to know about that.
same here, i hade atleast 200 VRT there

It is nearly OK, just change Trullala to Bufius (new nick, also in irc channel now
and give credits for source adaption to me and for windows builds to Aleks.Excellent work, thanks Bufius.

Thanks. Sent you some VTC.

Thank you so much Bufius, just let me know if I give the wrong credit in first page or in the website.

and give credits for source adaption to me and for windows builds to Aleks.For everyone reading:
- yes, hashing speed is ~50% of normal scrypt because the main (memory and work intensive) loop is 2048 cycles instead of 1024 for normal scrypt.
- during the upcoming changes of nFactor, the hashing speed will half every time = every year
- for now, TC needs to be lowered to ~80% of normal scrypt (as a starting point). I cannot give a better estimation, need to understand cgminer and opencl code in general much better to do this.
- try to change TC to something like 256*x (for me this works OK)
- for my 7950s i use 19712 = 256*77 without HW errors @1000/1500
- 5770 is at 4096, also no HW errors @ 925/1350
- playing around with the lookup gap is also possible if HW errors occur, but everything != 2 lowers performance.
- increase to 4 or 8

Hi,
i am the originator of the modified cgminer for CPU and GPU.
As i have done these modifications for linux there is of course a linux source available (but i have not done a binary package yet).
Aleks made the windows version then (many thanks to him, my windows build env is not ready because my rig is linux only).
I will try to setup a git later (after work) so you can checkout the sources by yourself.
There is a lot of work to do - remove the hardcoded nFactor and replace with an adaptive one (needs lot of testing because i see some issues with adaptive TC).
I cannot give you an ETA, but for now (the next months) both current versions will work.
And unfortunately the CPUminer is not very fast but an adaption of the fast minerd was not possible for me because the fast part is coded in assembler...
The same nFactor adaptions needs also to be done in the pool SW as it is hardcoded too atm (you see: lot of work to final version).
