7950's go almost as high as 280x's on your public kernal Wolf0... top work.

all 4 are built with hynix.

asus 280x with hynix does 170khs and elpidha 280x does 150khs. so the 7950 fits in rather nicely.

Can u give me ur config bat please for 280x

Thx in advance

Because i only get 115khs on r9 280x Toxic version

for 280x use 14.7 rc3 drivers as 14.9 seems to limit output of the card. -w 48 -i 13 -g 3. and fiddle with the core and memclocks to reach a comfortable stable speed. if you have hunix memory it would bring you past the 160khs mark, if its built with elpidha then between 144-150khs with my config.

Thx it works

Since this seems to be the thread with the best Wolf0 Neoscrypt info, I figured I would share what I have been able to work out so far...

I am running 2, 6 x R9-290 mining rigs.

Mining x11, memclocks set to 967 (optimal imho), and powertune at -15 for power economics, they average around 32Mh @ 1210W each.

Mining Neoscrypt with  Wolf0's Nov 2nd SGMiner5 build, I have been able to get around 1Mh (930avg) @ 1450W per miner. This unfortunately is "not" using his awesome personal neoscrypt.cl file or I am guessing I would be putting out about twice the hash with probably a bit less power usage. Since this is the unoptimized "release" cl file (yet still better than any other versions I have yet run across), with today's crypto values, it is still mining pretty close to break even power/profit wise so I needed to back the memclock setting down to 924 to save a few hundred watts for economics. The 924 setting does hold back the maximum available hashrate a small amount...

Using my own batch and conf file with fallbacks on the first miner, about the best I have been able to get looks something like this...


On the second miner, using just a batch file with Wolf0's settings that I pulled off of another thread, changing the worksize to 32, and bumping up the intensity just a touch;

Code:
color 0A
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
rem Intensity 15, worksize 64 for all
rem TC 16384 for 270X, 49152 for 280X & 290X, and 32768 for 7950
rem GPU threads 1 for 270X, 280X, and 7950, and 2 for 290X
sgminer.exe -k neoscrypt -o stratum+tcp://east01.us.trademybit.com:8880 -u "username" -p "password" -w 32 -I 18 --gpu-engine 924 --thread-concurrency 49152 --gpu-powertune -15 --gpu-threads 2 --no-submit-stale

It looks something like this...


This has taken me a couple of days of forum digging and configuration changes, weeding out crashes, rejects, and sick and dead cards so I hope it can help save someone else a little effort.

And I want to give a huge shout out to Wolf0 and give him props for his exceptional work. Not only on neoscrypt, but on all of the GPU algo's that he has spent his time on. While I sure wish I could get a hold of some of those personal optimized cl files he is holding back, there is no question in my mind that without his efforts and what he has already shared with us and other developers, there would already be a lot more GPU rigs headed for ebay and the scrap yard including mine. His work and that of savvy coin developers using the less ASIC/FPGA friendly algos, is helping to keep decentralized CPU and GPU mining alive. In my humble opinion, that decentralization is key to a fair crypto future.

That said, Wolf0, In appreciation of your efforts, I'd like send you a bounty of 10% of what I have mined with your neoscrypt software to date... I have been multiport mining on TMB with it, so its all in FTC and UFO... Can you list or PM me FTC/UFO addy's, or would you rather I convert em to BTC at todays market value and send to the LNc7w8HpAFJCnhbZqS3nmDwZP6h2Rrbqzn donation address?

Thanks again,
Hatch

My rigs are using about 13% more with neoscrypt over x11.

I saw wolf0 mining at 240k/s with 280x how does it possible?

So majsta, why are you posting here if you dont wanna share ? Are you just bragging about your hashrate, and give no information to confirm it ?

I can confirm majsta's settings do indeed work. I can now get ~320 khash on R9-280x cards, and ~130khash on R9 270x cards. Thanks majsta!

The information is out there, you just might have to work a bit to find it, which I believe is the point. Not everything is going to be handed to you on a silver platter.
