catalyst 14.x drivers dont work with this miner???

never had any luck with them, nope.

So low hashrate ? Really?
At Nf(14) its value was ~2.9 Kh/s. Do you still continue mining YAC ?
Yes, I read the last 2 pages, but I meant min amount RAM for 1 card.

Hi

Can someone please say what's max. hashrate from one R7 240 4GB at NF=15 (YAC mining) today ?
And, what is the min. amount of system RAM required to mining without HW errors?


1.196 Kh/s today. Let's see what tomorrow brings.
8 GB works for 4 cards.
Next time you should at least read the last 2 pages.

Hi.
I have a problem with mining YAC on my Radeon 7950 card.
My command-line options are:
yacminer --scrypt-chacha -d 0 --worksize 128 --lookup-gap 8 -g 2 --buffer-size 1295 -R 2560 -o stratum+tcp://yac.coinmine.pl:9088 -u X.1 -p Y --nfmin 4 --nfmax 30 --starttime 1388361600

also I`ve tried another options:
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 2590 -R 5120 -o stratum+tcp://yac.coinmine.pl:9088 -u X.1 -p Y --nfmin 4 --nfmax 30 --starttime 1388361600

where I could be mistaken?

That's the wrong starttime for YACoin.  The starttime for YAC should be 1367991200 (you've put in Ultracoin's starttime), so you were mining at nFactor of 13 instead of 15.  Be prepared to change your other settings to work with NF=15... (You will get HW errors unless you lower your -R)

But in both cases i receive:

Rejected 626b9dc7 Diff 1/1 GPU 0  (Share is above target)
Rejected 90b24df8 Diff 2/1 GPU 0  (Share is above target)
Rejected eaa24967 Diff 3/1 GPU 0  (Share is above target)
Rejected 5ca82134 Diff 17/1 GPU 0  (Share is above target)

The 'A' counter is zero, but the 'R' counter in yacminer main window is increasing.


The hardware configuration is:
2xR7950/3GB RAM (tested only on one card is you see)
4 GB of system RAM
Windows 7 64bit
Catalyst 13.9 drivers
AMD APP SDK 2.8.10 64bit
yacminer 3.5.0.

where I could be mistaken?

I wrote a tool that is hosted on the ultracoin website for configuring your miner.

Go to http://www.ultracoin.net/configgen_raw.html and put in your card, how much memory it has and select NFactor = 15 and click the button.  Start with the settings it gives you at the top - something like this for a 2GB card

Code:
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 1648 -R 1536 -o stratum+tcp://: -u -p

Also, read all the text that's there - I wrote and/or updated all of that to be specific to mining high NFactor scrypt coins.  It's not easy unless you're an expert, and there aren't many experts.

(PLEASE NOTE : REMOVE THE NFMIN, NFMAX, AND STARTTIME IN ANY CONFIG IT GENERATES FOR YOU AS THEY ARE SPECIFIC TO ULTRACOIN)

I have Radeon 6970(2GB).

Please, can you tell me for sure whether it's suitable for mining of yacoins?
I've already tried to run yacminer v3.5 with diff settings on my system (Win7 x86, 2GB of RAM),
but I got HW-errors.

I will be very grateful for any advice.

Wondering if you can try to implement CryptoNight algorithm into your miner? There is an open source bounty out: https://bitcointalksearch.org/topic/bounty-for-open-sourced-xmrcryptonight-gpu-miner-bounties-thread-656841

CryptoNight is suppose to be memory intensive, so it might be like mining YAC.

Just to benchmark, on a single core one thread cheap Pentium CPU, I got 25H/s using the non AES-NI enabled CryptoNight miner. (AES-NI enabled CPU hash is much higher) On your CPU Yacminer mining YAC, I got 55H/s.
The high end GPU only get 500H/s, but for YAC even the low end GPU get 1KH/s at current Nfactor. (low end currently not so good at CryptoNight, r7 240 only gets about 50H/s when I tested)

Even at current N = 15, GPU is still more effective than CPU at mining YAC, but for mining CryotoNight coins like XMR, there is no advantage. But I think its because the code is not optimized.

Can you take a look at this algorithm and see if its possible to make open source miner for it?



Edit: Here is Wolf's open source CPU miner for CryptoNight as reference: https://bitcointalksearch.org/topic/wolfs-xmrbcndsh-cpuminer-2x-speed-compared-to-lucasjones-new-06202014-632724

I'm assuming you can try to decipher how the hashing function works in his miner and try to port it over to your miner.

I'm also assuming that the way that your miner talks to the pool doesn't change even though it would need to talk to a pool mining a CryotoNote coin and not a Bitcoin protocol coin.

Thirtybird, how hard is it to modify your miner to incorporate new algorithm?

probably not terribly hard, but potentially extremely hard.  I was able to re-enable SHA256 and Scrypt, and Add N-Scrypt.  If someone's already done it in another miner, then it's on the easier side Smiley

Now that the Nfactor is over 14 I've tried experimenting with lower nfactor coins (ultra, micro, bdc) and nothing really looks that profitable with a R7 240 @ 2GB of ram...anyone got any suggestions on what they would do?

Maybe ZCC or YBC.  My R7 250 2 GB are still on YAC.  Not as effective, but no worse off than any other 2 GB card

--buffer-size 3712 --lookup-gap 3 -R 4992 -g 1 -w 256

Set your R to 1280 - you want R to be 4 time the number of shaders on the card.  Hashrate goes down if it's in excess of 4x unless its an even multiple of 4x the number of shaders (2560 gives the same hash rate as 1280 - it's pretty weird)

Yeah, I'm doing something like that but I still get the odd hw...meh.
I'm back to folding for now, might get back into yacoin if I figure it out but for now I don't have time to tweak it sadly.

Can someone please post parameters for R7 240 4GB at N=15 ?
I can not get it over 820h/s without hardware errors.


can you not read back LITTERALLY three posts from yours?

I tried that trom ivanlabrie and it crashed my driver. But it works with lookup gap raised to 3 (3 posts back, as you stated).
I got 1Kh with this:

--buffer-size 3712 --lookup-gap 3 -R 4992 -g 1 -w 256

Thanks.
