13.12? Why such an old driver?

I'll continue to play.

It's what was out when I started this experiment and the 14.x drivers gave HW errors mining scrypt-chacha when I tried them. Now at this point, I don't feel like tinkering with them because "they just work"

My 270x max out at 2.2 khs on Nfactor 14...

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
del *bin
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 -R 3200 --buffer-size 1696 --gpu-memclock 1400 --gpu-engine 1000

I've tried 13.12, 14.6, and 15.3 drivers, no noticeable changes. The buffersize is the largest I can make it. Is there anything else I can play with to get more juice outta these cards? Thanks in advance.

@ Thirtybird

Don't laugh at me. I get bored (and sometimes I am dangerous).

I am playing with Windows 10 and trying a 750ti with your miner. Long story short, new Nvidia driver supports OpenCL so I am playing with it to see if this will work.

When running the miner I have just a basic setting, besides the nfMin = 4 nfMax = 30 nTimeStamp = 1388949883, I just run the -I and change it higher until I get a HW error.

It does find the card and mines but it does not connect to the pool. The miner shows it and running but the pool does not show the miner active and I do not get hash rate at the pool.

Is there some setting I might try that might be specific.

Again, I am just experimenting to kill time and see if it works.

EDIT: Under Windows 7 with the exact same bat and Nvidia driver it does not find the card. Says no OpenCL device found or something like that.

Is it possible that it just was minign so slow that it never found any shares for submitting? I seem to remember something about the nVidia cards supporting OpenCL (Even from the beginning), but they were horribly slow at it. Post a screenshot of the thing mining? That will show connection status and mining speeds and the like

Here is a screen shot but something I did not notice until I put the log in the bat (thanks Wolf0). The miner shows that it is at a N-Factor 17 but here is my exact bat that I run for N-Factor 16:

yacminer --scrypt-chacha --nfmin 4 --nfmax 30 --starttime 1388949883 -d 1 -o stratum+tcp://pool:port -O xxxxxxx:x -D -l 5

That's kind of interesting. If you look at the pool line it is showing "diff 2 NF 16" but your debug output shows NFactor 17. My miner on my system (that I know submits shares) actually shows "Nfactor: 17" in the debug output too, so that's likely inaccurate, or based on 2^NF instead of the scrypt-chacha funky math of 2^(NF+1) or something like that - it's been a while, but it's always been confusing (thanks pocopoco!). I think you've got it working, but at that hash rate, you're likely not submitting shares, or are hitting HW errors instead of accepted shares.

Since you did not specify buffer_size or lookup gap on the command line, the default values are going to pick ~90% of the GPU VRam it can see and a lookup-gap of 4, which is not ideal for NF=16, and is probably giving you HW errors. What buffer size does it tell you it's allocating for the card when it starts up? (likely need to turn debug off first)

You are correct on the look-up gap of 4 and the buffer is being set at 448. After a while of mining I do get a HW error.

If I change the starttime I get a high hash rate but all rejects.

Show me the output of yacminer -n, would you? Also, for Win 7, try diff OCL platforms.

Here is what I think you mean. Again I only have a setting of -I 8

2.7?! I barely get that outta my 280x's.. What AMD driver do you recommend? 14.6 is the one I'm using.

GPUz is a cool tool, but it is showing me everything is correct as far as I can tell. Each card has 2 GB, memclock at 1400, gpu-engine at 955. I'm starting to mess with the lookup-gap, but I thought that was just set by the NF number. ..

13.12
My R7 240 4GB cards NF=14 at 2.8-2.9 KH/sec (depending on the card) even though they have fewer shaders. It's all a matter of allocating the largest buffer-size you can and then testing each of the lookup-gaps with the corresponding max R for each one to see which one to settle on. The 4GB card can run a lookup-gap of 2, whereas I had to go with LG=3 on the 2GB card. It's all in the tuning guide I linked you to

Yes, I'm familiar with the readme

The config suggests 824 with 2 threads. I seem to have 1 of 4 270x's that don't mine properly with the config; its finicky (Getting like 50 hs) so I tried to let yacminer decide the buffer and it decided on 446 MB. Didn't help too much. Using -g 1 crashes the miner as well. If i restart it enough, sometimes it will start mining but it didn't make it through the night last night.

timeout /t 30
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
del *bin
yacminer --scrypt-chacha -o stratum+tcp://xxxxxxxxx -u xxxxxx -p x --nfmin 4 --nfmax 30 --starttime 1402845776 --worksize 128 --lookup-gap 8 -g 2 --buffer-size 824 -R 1600

Furthermore, I cannot get past 2 khs, and it seems to be more stable on 1.8 khs. Is this all I can squeeze out of 270xs?

If you haven't run GPUz, I highly recommend it for troubleshooting. YACMiner is looking at how much memory it sees, and allocates 90% of it if you do not specify (512 * .9 = 460), so you're having trouble where you cannot allocate all of the cards memory. It will also show you how much memory is allocated to dedicated memory vs dynamic memory. If your hashing buffer winds up spilling into dynamic memory, your hashrate is going to be dismal.

My notes for NF=14 had my 2GB R7 250's hashing at 2.7 KH/sec, so you should be able to at least match that once you get your problems sorted out.

Does anyone have an r9 270x config for nf 14? Keep getting HW Sad

http://cfg.ultracoin.net/

Thanks! I am aware of that, but when I punch in the listed config, one of the 4 cards is only hashing at 60 h/s and then crashes yacminer. Furthermore, each card is only getting around 2 khs on each card which is pretty poor performance considering I'm getting 3.6 khs on 750ti's. When I allow the auto-buffer in 3.5.0, it buffs 446 MB. What should the rawintensity be with that buffer?

446 MB? you are trying to mine with a 512 MB card?? If your card has more than 512MB (which I would guess it does), you probably haven't done the commands to allow you to allocate more than 512MB. There is a very detailed readme that comes with the miner (SCRYPT-README) that gives you lots of information on how to tune your setup. If you've deleted it, it's always on my github source site

YACoin
ZCCCoin
Ultracoin
LeoCoin

check out the NFactor spreadsheet in my signature - it gives a comprehensive list of the active Scrypt-Chacha coins that are out there and their N Factor change schedule.

What I have to consider before compiling it for a special coin on my linux machine? For example for Ultracoin. Is there a config file which has to be changed (nstarttime for example) before start to compile? Thank you
