Yeah, sorry I didn't specify, it's pretty late here.. That is my own code adjustment and if it's not added as + 1.. it would fit in a 32 byte address..(Theoretically) so nothing would be wasted.. should be an 8 times increase.. at least in memory speed.. if it fits without +1 ..and if there is some need to have 256 byte for a video's memory.. I'll understand, but would like to wonder why. and if so.. instead padding memory like the ones before have done.. actually times the hash by 7 or 8 beforehand filling up 256 registers almost and then padding if necessary... many ways to come to something fun and workable i suppose.

But if you made your own, and isn't forked or anything from them.. is that how you have it somewhat? maybe 32 or 64?

are you referring to xmrig ?

If you didn't build the whole thing your own that is, check out a line that has i believe a "224u" line in it assigning a value to memHash..which is padding for a 256 byte chunk..so it should be something that takes it out at way before 255 and bam, well just comment it off and add + 1;  How stable is it? i've only ran it an hour... but if it can do ~2-5 hashes for me.. imaging what it may do for multiple not using the basis of bits..


try a good test on a more speedy video card with that..doing before fix and after fix results and of course will it stay running for an hour or 300?
it's in auto config... source.

Thanks!

Well that 2% may be more than you think, since that is probably all real people most likely just trying out mining or doing it as a hobby and when electric may not be an issue, or many others.
It can also improve on speed for killing outdated shares and work.. pretty much instantly start working on a new task. But yeah tons of people on dedicated mining rigs.. I'll get there eventually.. right now I just want to get the most out of what i can.. since i've known it's limits.. can translate well into newer optimized code too.

Also on that other parts of a miner.. Those are a hassle, but end result is always good, was thinking of a CLI that did a refresh and a moving graph of all gpu's kind of like an equalizer and show hashes accepted, round trip time.. averages, highest number of share_per_card .. but that's another fun story for some beautiful client miners that have never been done before, far as I've seen yet anyways.. most is just what's the hash? is it still running..how many shares.. it should be "what's my temp? and what's my wattage/heat ratio to kWatt" and preserving these new cards that do need to be resold someday..

wow , long post
To tell you the truth, at the moment i have more important things to improve on the miner. Yes, surely lagging is a problem, but since mining is 98% happening on rigs, where you don't need a responsive ui, it really isn't a problem

If you come up with something , surely i can integrate it, so that 2% of users can get a responsive desktop, with minimal hash drop

Do you have yours set up like this.. for example let's say I have 4 cards and i only want the last 2 of them to run for some reason..it would look a little like this..


the "id" is what you are looking for.. numbers start with 0 being first card.. Have you tried running it with -listdevices in your start.bat batch file?

OH also forgot, did you take out the leading /* gpu_stuff here, yada, yada. and then there is another closing comment as thus */ which will also stop it from being used.

Nothing really can help that without the kernels that are executed. This also happens on any other gpu miner as well right?

For everyone:

     I'll explain a bit about OpenCL and how the "kernels" work a bit..
The kernel or "payload/work" is sent to the video card and is kind of like a singular pipe, okay that analogy sucked, but imagine
with all the "CU" Compute Units available.. the work from these kernels are sort of like threads on a miniature scale and they all
work according to the OpenCL standard (Hopefully) But it's like a faucet.. turn it on or off.. also you may need to turn down intensity
even more until you have a freeze free desktop which costs all the extra hashing power you would have had.  Remember on SRBMiner you can
use decimals so don't forget that ex: "intensity 20.3" or what have you.

     I've left an earlier comment on a "low intensity" mode that is about splitting
up one big time job to do work into much smaller timed jobs and if done right, it really shouldn't have any negative impact on hashing speed,
or at least any notable impacts on it so that could be maybe be a modulation of 100ms or 1/10th a second per command queue or even smoother
by doing it roughly ~16.67ms for 1/60th a second, but I'm getting a bit to technical trying to explain it.. Anywho, a good way to perhaps implement
this would be to take an argument for say --desktop_mode ex. --desktop_mode 25 and plug that in which would do 40 pulses_per_second.

     I'm not the most intelligible on OpenCL and gpu kernel work, but to the best of my knowledge this is the only way that claymore/phoenix miners are doing this,
please correct me if I'm wrong (Which I probably am on a few things ).  Since I have no source code to these miners, I've been doing a bit of work on XMRig-amd
and testing my findings out on that.. So far I haven't got into splitting up kernel execution times, but i did turn an almost static 32H/s into 35H/s by redoing a bit
of the way the kernel maps memory.. Not sure how big of an improvement it would be on a real card, but it probably would give a good bit more hashes on other cards..
I'm only able to test with an amd radeon HD6530D APU setup and the maximum i've ever got it to do was 42H/s at a slight bit of OC on claymore and around 50H/s if i jacked
timing up to almost 700Mhz from stock 444Mhz for this cards core..(Probably wondering to yourself how that is even achieved with these old APU's?? I call it part of the good
silicon lottery.) If you have an A6-series or A4's or whatnot, I might be able to also help with clocks and suggestions...

     Also if anybody would like to try and help coding for and helping SRBMiner be the serious go to for cryptonight mining with this low intensity thing and kernel work.. I'd gladly
accept the help and can set up a private git branch that we could work on that through xmrig source, if the Doktor gives an ok on doing, he could throw it into SRB with perhaps
minimal changes and nothing else will have it.  My goal as a mining hobbyist is to make these miners work on pretty much all driver versions (Except the ones like the crimson beta
which doesn't include anything to use far as i can tell...)

Drivers tested with using DDU (Without Format):
  14.4 - Confirmed as working and stable for pre-GCN cards.
  15.7 - Can only confirm that it does not work with A6-series Apu's without driver crash.
  15.11 - Also same as 15.7.
  16.2.1 - Forget about it... for pre-GCN computing.

     Perhaps I should just ask Doktor if he in any way, shape, or form would like to collaborate even?  I tend to use bitbucket for it's private git repositories with things such as these.
And by the way, here is something to talk about.. not sure if there is a rant section, but people that totally pack their miners and put in disassembly code that shuts off a miner for
having any debug software going, or show's faked hashrates to ppl who use nofee or cheats as they worded it, or are those numbers not just higher in the code.. SRB i'm 99.9999% sure
there isn't any of that since we're all getting just about the same hashes on all the open sourced ones, but this seems a good bit more optimized already with more share turn in's
compared to hashes, perhaps Dok already found those memory speedups Okay, enough of my novella.. Thanks.

I'm having issues using certain GPU's.  no matter what I change, when I start the miner it starts all mu GPU's instead of the ones I choose.  its like the gpu conf section is not overruling everything else like the readme file says it should?? I'm pretty new at this so I'm sure its something I'm prolly doing but I could use some help!! otherwise I love the new miner!!  thanks

Wow thank you very much. We can expect it in the next version?
Can you give me some advice for fine tuning my r7 370-s and rx 470s for all cryptonight versions, because on all types of algos, my desktop is little freezing, even on default settings, or even a much smaller intensity.

I think is a pool/network issue

miner work but why i see error ...?

https://image.prntscr.com/image/dadhXyZdTg6uZNmPI3QPWQ.jpg

i try with low mem clock and low gpu clock but error again.

How can I specify individual devices?

@doktor83 is it possible to order card like gpu-z and hwinfo ?

Is it possible to add name for different card? May be it possible to write any information in bios to identify card. It will be good if any card is broken and gpu numbers changes and config was broken.

From readme and first page :

I lost the page in which was stated how to make fine tuning of intensity workspace, memchunk etc.
Doctor, may you place it in the readme ?
Btw, you lost the logfile option in the readme as well

difficulty is set by pool , not miner. Which pool you use, maybe they don't have stat. diff setting.

Trying mine IPBC and using 1.4.6 srb miner can't set difficulty at 30.000 it always going up . Anyone know how to set it ? Wallet address "." "+" dont work .

Does anyone uses SRB on RX 580 8gb with hynix MJR memory? What speed and settings?
