[ANN][GRS][DMD][DGB] Pallas optimized groestl opencl kernels

[echo00114]

Have anybody tried with 270X cards - what hashrate should I expect?

hello
i try saphire toxic but not good all hw error and i try lower gpu mhz but not work 1150 mhz still 1150  o use grs-sgminer 1.4 i use 14.6 amd driver rc.

bye
update 1:
i try different miner sgminerGroestl4_1_0_1  and this cl working great 9.7 mhs  I 22 and  I 20  9.5 mhs 

bye

since I've never tested it on 270x there could be issues, but please try:

- using the bin file from the OP
- lowering the intensity
- lowering core speed (are you sure you put the ram clock to the lowest possible value?)

since it uses more power, it could be a cooling issue too.

If he is using grs-sgminer then he must be using cryptohunger pool which would be incompatible with
a real groestlcoin kernel ... have to use sph-sgminer, not proprietary grs-sgminer with this kernel
cryptohunger requires grs-sgminer, so move to a different pool if you want to try this kernel or just solo mine like I do

The version I have proposed, goes perfect with 13.2. go to control panel, uninstall 14 and then select install driver 13.2

7950=13Mhs I 21
7970=14-15mhs I21
But these optimized versions hotter than the GPU and more electricity...

fine, thanks, but my kernel is faster...

[cryptonit]

21 mhash amd290 at 1020gpu clock
pretty powerhungry (dual 290 are around 150w more useage on this than on x11)
but its the best groestl amd miner i did ever see regarding hashrate per card
great job!

i still use http://multipool.bit.diamonds/ (able mine DMD with nearly any existing algo)
amd cards running x11 most time and nvidia cards nist5
becaue at austria powercost i need to be very poweruseage sensitive

no mining gear? still wana have a constant DMD income? check out DMD Cloudmining
no electricity no heat no maintainance
one time invest forever DMD payouts!

DMD Multipool total earned DMD jumped across the 10000 DMD mark!

Pallas, you are great!

Here are my numbers:
290x @ 1125 Mhz ~ 26,4 Mh/s
290x @ 1040 Mhz ~ 24,4 Mh/s

I am going to send you 20% of the next ten blocks I will find,
just because I want to donate to an honest and sharing person.


To use the bin file correctly, you have to remove all bin files in the main folder, download pallas bin file, put it into the main folder,
start your miner, copy the filename of your automatically created bin file after you started the miner. Then you stop the miner and rename pallas bin-file with the copied filename.

Hi guys!

I am not sure if you understand it yet, but your profits are not going to increase. Unfortunately. :-(

Perhaps in the upcoming 5-10 days, but then it'll all be as before. And you'll be paying more for electricity.

That is one of the reasons I did not open source my miner.

Cause not only you are going to move to the faster kernel. Everybody will move to the new kernel.
So not just your hashrate will increase, everybody's hashrate will increase as well.

And so, the total coins distribution between miners will not change, but you're going to pay more to electricity companies.

The new kernel eats a lot more electricity and makes more heat.

Which is bad for the algo we're mining.
Also it makes CPU mining a lot less profitable compared with GPU mining. Also bad.

The root of all evil,
srcxxx

hmmm not exactly.
the biggest miners are already using optimized miners made by themselves; this kernel puts the common people on a higher level so they can compete.
smaller miners will make more coins and biggest ones less.

Hi, sorry but I don't see where I can download the last sph-sgminer???<
Thanks

Maybe it would be a wise decision to use a power saver kernel in summer, to enhance your graphics card lifetime and a more power version in winter to keep your feet warm

Or just lower the core clock ;-)

You can use the "classic" version as well as the new version 5 (and probably other similar miners).

Excelent work!

Got about 15 MH/s for my Gigabyte 270X compared to 13 MH/s previously.

Is it possible to release other optimized kernels? Qubitcoin for example?

Yes some improvements can be made but I have no time to dedicate to it :-)

[pallas]

Can someone please post a 32 bit Hawai or Tahiti binary?
The filename should end in "256l4.bin".

[utahjohn]

has anyone tested this with sgminer v5?  I am currently running sph-sgminer 4.1.0

[pallas]

if someone is still getting hardware errors, ensure you are using a worksize of 256 (-w 256 on the commandline).
some optimizations depend on it so don't set it to a lower value.
also don't set it to a higher value simply because 256 is the maximum and that value will be used instead.

Congratulations Pallas.

Do you have it on Github already?
