Topic: [VTC] Lyra2RE Vertcoin optimized miner, NOW WITH SOURCES! (Read 26867 times)

I picked up an HIS R7 240 card (on sale for $30)  2GB memory.
 
What is the max threads I can run on it?  Been running 2 just fine. 

Also what is the limit to how far I oc it w/o burning out the card?   

I am thinking about it, but need something which can hold some hacking  
also the other problem is that I need to hard code pool names, with whirlpoolx that was rather easy but lyra must have more pool...

You can release it with a fee like you did with the whirlpoolx miner. Lyra2 and the other memory algos are heavily infected with botnets. Time to show some GPU power.

Thank you for solution.
I put amdocl.dll file from catalyst 14.9 (C:\AMD\AMD-Catalyst-14-9-win7-win8.1-64Bit-dd-ccc-whql\Packages\Drivers\Display\WB6A_INF\B176041)
to the miner folder, and all cards works well, even on drivers 15.5 beta 

The miner has been developed on omega drivers (14.12) but it is reported to be working fine and as fast on newer ones - BUT - some users have reported half hashrate on the first card and fixed it by installing catalyst version 14.9.

@pcste

There has been various reports of people having similar issues to yours.
First of all, it looks like there is some sort of issue with the first card of the setup under certain conditions. I noticed this as well: my card 0 hashed but never returned a share, on multiple algos, including x11... but not all :-)
Another issue is that of half hashrate for the first card. I could never reproduce this problem. It seems to depend on the driver version, though.

What I can tell you is try with the precompiled binaries, also try 4 threads which seem to give better results on 280x (and slightly worse on 290x, at least in my case).
You can also try making your binaries with different driver version without reinstalling them, just by copying the opencl.dll file into the sgminer folder.
About hardware errors, are you sure the ram of your card can run reliably at 1500? Not all 290s can. Unfortunately such high ram clock is needed for lyra2re to go fast.
Finally I see you remove bin files in your 280x bat file, but not in the 290's, are you sure you removed the bins after installing the new drivers?
And superfinally I'm not sure 100% that two running sgminer instances are good: there is some bug about device selection on sgminer, so I wouldn't do it if possible.

Hope that helps

Hi Pallas
thanks for the work you've done. ive run my rig pointed at your address while setting up my miner, and will do so some more once i get
things running ok.

Currently im struggling to get my sapphire r9 290 over 850kh
i also have a dual x r9 280x in the same rig which is getting 1016kh

i originally tried the r9 290 on its own and was getting 1300kh and read at the begining of your post speeds of around 1700 for a r9290
so i upgraded to 14.12
i also introduced the r9280x and then made 2 bat files so i could run 2 instances of sgminer.
Now im only getting 800+kh on the r9290. and its hit and miss as to whether i get HW errors. sometimes i do sometimes i dont (even with the same settings)
I wonder if you can enlighten me as to what i am doing wrong?

I am using amd 14.12 omega, sgminer lyra2re win.

here are my bat files for the 2 cards

r9290 bat file


setx GPU_FORCE_64BIT_PTR 0

setx GPU_MAX_HEAP_SIZE 100

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_MAX_ALLOC_PERCENT 100

sgminer.exe -d 1 --remove-disabled --kernel Lyra2RE -o stratum+tcp://eu.p2pool.pl:9171 -u VsLK3LaqdGijDVq6HSGbSWfQJhtzFGSBKr -p x --no-extranonce --no-submit-stale --expiry 1 --scan-time 1 --queue 0 -I 19 -w 128 -g 2 --gpu-memclock 1500 --gpu-engine 1000

ive tried intensity 15,17,19 all give me similar hash. same with memclock and engine 835,1500 980,1500 1000,1500 980,1250 all give me similar hashrate

r9280x bat file


setx GPU_FORCE_64BIT_PTR 0

setx GPU_MAX_HEAP_SIZE 100

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_MAX_ALLOC_PERCENT 100

del *.bin
sgminer.exe -d 0 --remove-disabled --kernel Lyra2RE -o stratum+tcp://eu.p2pool.pl:9171 -u VsLK3LaqdGijDVq6HSGbSWfQJhtzFGSBKr -p x --no-extranonce  --no-submit-stale --expiry 1 --scan-time 1 --queue 0 -I 17 -w 64 -g 2 --gpu-memclock 1500 --gpu-engine 835

p.s. currently im not getting any HW but the last time it ran ok, when i re-booted i got HW. stopped mining, left the pc running for a while then started mining with no HW errors.

The power consumption would be around 110W each 280X card.

What  about Power consumption?Do you have a wattmeter?

I stand corrected.   I know I was originally useing one that was opencl.  I got mixed up as to which was what

Sorry for delay in response, i had a busy week.
Yes, almost all card, only VTX, CLUB3d, Sapphire OC may need little more like 919-925 mV.
On Gigabyte,Asus,MSI,Sapphire Trix/Vapor no problems with 900mv.
Just set 715Mhz Core clock and 1500Mhz Memory Clock and core voltage 900mV in MSI Afterburner.
You must only know, Gigabyte WF3 cards, and Sapphire Dual-X OC 280X , have locked voltage.
But that's no problem if you know how to modify cards bios with VBE7.0.0.7b.exe from:
http://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/
If you don't know i can help with that.



a lot of savings in energy and less heat generated, that's on Asus 280X DCUII. Below 900mV

No a GTX 750TI is getting 700-900k.

clearly ...

but what i have found is that unless the miner is bought in the 'highs' at the time - then mining it a getting a roi on the investment of the miner is almost non-existent ...

my calculations for some of the miners / algos that are going around at the moment for 3btc and more is just too much for what they are ...

some will pay - others wont ...

we are one of the farms that WANT to have a continual donation to the devs ( like yourself ) that do such a good job - rather than just have a one off payment and be done with it ...

which is why we always present an initial payment + mining for the equivalent of the fee that devs ask for AND donate via mining on a regular consistent level for an agree and arranged time frame ...

great work though ...

let us know how much you are willing to let the miner go for ...

...

#crysx

clearly not for nothing 

nice ...

looking at releasing this in the near future djm? ...

#crysx

ccminer-spmod uses cuda - and will get around double what you are getting using opencl ... and thats on our stock clocks ...

there are others that overclock and get in excess of 900KH per 750ti with sp's fork ...

try it out ...

amd - different story altogether ...

#crysx

ccminer with opencl  (yeah why not...)

current speed on an unreleased ccminer lyra version:
750ti: 1140kh/s
780ti: 2800kh/s
980  : 2400kh/s

Which software do you use to change the card settings?, I have 2 sapphire dual-x 280x and with MSI Afterburner I cant change the voltage, only the core and memory mhz.

LOL
ccminer is using CUDA. Look to sp_'s ccminer thread )))

current pool stats
r7 240 @ 266k   gtx 750ti 475k  cpu 419

the nvidia is using ccminer with open cl


I've seen the nvidia in the 700k once. cpu seems to always be the fastest


between all 3 I've been as high as 1.2Mhs. that was before I started tweeking the R7.  the 750ti is running @ stock.

edit: r7 is 266 khs   gtx 750ti 671 khs cpu 371 khs. 
Haven't done any further tweaking.
