I can't get right settings for 7950, what settings should i use?

You need to say how much memory the card has... post YOUR command line and I'll explain the differences that need to be made.

I tried the command line you posted above for R7 250. my card has 3GB memory

It's going to be wild speculation - you WILL need to experiment on your own, unless someone wants to loan me one for a week or so, then I'll have the perfect command line

Code:

yacminer --scrypt-chacha --worksize 256 -g 1 --lookup-gap 8 -R 5120 --buffer-size 2560 -o stratum+tcp://yac.coinmine.pl:9088 -u username -p password

You've got so many shaders and can't use them all at lower lookup-gap values, so we try here to use them to trade off for the lack of memory by increasing the lookup-gap. 8 is probably a decent place to start (we like 1,2,4 & 8, the others are oddball sizes). I'm assuming you can allocate 2,560 MB in one thread (i.e. you have more than 4 GB system memory - if you don't you are going to have a bad time), and at lookup gap of 8, that amount of memory can only support 5,120 simultaneous threads at N=14, so that's the value for -R.

Another theory would be to try lookup-gap 12 and -R 7168 - I don't think the extra work being don by the extra 2048 shaders will make up for the extra 4 runs through on the lookup gap, but like I said... wild speculation

ok tell me if this is normal, i used your suggested command line, first time i don't see any HW but rate is just 5kh/s is this normal for my card?

That's a pretty great rate for a card mining YAC.... compare it to all the cards on the YACoin wiki /index.php/Mining_Hardware_Comparison]http://[Suspicious link removed]/index.php/Mining_Hardware_Comparison and you'll find it compares really really well... Now that you aren't getting HW errors, overclock it until it's unstabe! (and then bring it back down until it is stable...)

enjoy your hash mate - none of my cards get over 3 KH/sec

Ok thank you that helped a lot. yeah i get 4.97kh/s stable with no HW
I will post screenshot after some attempts of tuning

5kh/s out of a 7950?

That's pretty crazy... Huh

It's only got 3 GB - I'd guess > 7KH/sec if it had 4 GB and overclocked well

That'd be insane...I mean, haven't seena any do so well, but haven't tried it myself either. hmmm

It sems that A and U are simply multiplied by 16 when mining MRC.

7950 is down to 80 Mh/s again with --rawintensity 6400 or 7168 Angry

There's more math to it than that, but if your pool doesn't use vardiff then, yes, they will be different by a multiple of whatever the pool difficulty is.

YAC: R7 240 4GB

Code:

--scrypt-chacha --buffer-size 3376 --no-submit-stale  -w 256 --rawintensity 1280 --lookup-gap 2 --gpu-threads 1

2.9 Kh/s

MicroCoin: crappy 7950 3GB

Code:

--scrypt-chacha --starttime 1389028879 --buffer-size 2100 --lookup-gap 2 -w 256 --rawintensity 6400 --queue 0 --scan-time 2 --expiry 4 --gpu-threads 1

110 Kh/s

still testing

for MRC weird A and U (U=80)

Nice settings! The R7 240 4GB is spot on for my findings.

On your MRC miner - if your 7950 has 1792 shaders, I would see if you can take the --rawintensity to 7168 - everything else being the same. 6400 would be where I would be if I had 1600 shaders. A secret I'll share is that for settings that aren't memory limited, I just use "-X 4" and don't even do the math to figure out the -R

U of 80 isn't unreasonable for 110 KH/sec - if you're getting a lot of rejects or HW errors, that will suffer. If you're getting HW errors, (I would be surprised),lower the -R. That value also normalizes over a long period of time - some start off like gangbusters, some start out REALLY low, but they all work their way to an average after a couple days.

Here are the relevant settings I am using for my MSI R9-270 2GB to obtain 90-93khash/s on microCoin. Hope it is useful.

--gpu-engine 1100,1100 --gpu-memclock 1200,1200 --rawintensity 5120 --buffer-size 1400 -g 1 -w 256 --lookup-gap 2

One of my systems with 3 cards has since my post bluescreened so I might need to tweak it more to run stable.

thanks for help, but that didn't work for me on yac

It's for MRC/UTC, N 11.

Will try asap.

Fantastic update!

Using this mining microCoin and have been able to increase my system happy hashrate (ie no crashing) on each R9-270 card from 75 to 92 khash/s. That is a big increase.

Mrc is at N factor 11, right?

Mind sharing your settings?
