Claymore's CryptoNote AMD GPU Miner v11.3

[Claymore]

any news for linux multi-gpu fixes?

1. Multi-GPU: I tested miner on Ubuntu and Cent, on a system with 3 GPUs and I cannot duplicate this issue. So it must be something related to Catalyst version, or to Linux version that you use.
2. "Input OpenCL binary is not for the target!" error is not related to memory allocation error. It means that Catalyst cannot compile kernels, I can duplicate this issue only if I try to start miner for Catalyst 13.12 on the system with Catalyst 14.x or vice versa.

thanks for the response,
I will search for solution then

Nice improvements,working like a charm and thanks for less fee

WOW . This new Claymore blows away russian miner. On clay 9.0 1080/1250 270x 444hs -a4, same settings on russian miner -m 2 404hs. Can't wait to try 280x

"-a 1" is faster for 270/270X than "-a 4". For 290X/290/280X/270X/270 you can leave default parameters, i.e. do not specify "-a" and "-h", miner will apply best settings automatically.

For other cards, guide how to get maximal speed:

1. Try "-a 1", "-a 3", "-a 4" and select best mode, press "m" key to see immediate hashrate.
2. Remember "HashCnt" value when miner starts, then specify "-h" parameter with this value, remember hashrate and change "-h" parameter step by step by 32 in both directions (less and more). Select best value based on immediate hashrate.

I tried all mods for 270x(Elpida) and -a4 works best so far. -h is 512 by default, i did not change it.

I have 270 and 270X, both Elpida. For 270X I have 445h/s for "-a 1" and 436h/s for "-a 4". Well, the difference is small, so may be in some cases "-a 4" can be better.
Don't forget to use "m" key to see exact immediate hashrate. Main hashrate that miner shows can be less because miner calculates it as TotalHashes/TotalTime, hashes are not growing when miner is connecting to pool or when it is disconnected, but TotalTime is always growing. Therefore main hashrate value becomes less if pool is not working properly. But when you press "m" key you see "raw" hashrate based on one GPU round only, it is useful to compare hashrates for different "-a" and "-h" values.

Have any 6xx and 5xx cards. Minig with your miner, thanks :-)
Miner v8.0 working well.
Trying 9.0, see that:
Error in server response
: {"id":1,"jsonrpc":"2.0","error":{"code":-1,"message":"Lowdifficultyshare"}}
Catalyst 13.12. Why? Turning no help me. Returning to 8.0. Slowly, but good:-)))

P.S. With 270x-280x cards 9.0 all ok!

Send me first 20-30 lines of the log so I can see what card you use and "-a" and "-h" values.

With 8.0 it works ok.

[Claymore]

With 8.0 it works ok.

Probably you are trying to start miner for Catalyst 14.7 on the system with Catalyst 13.x installed. Use appropriate miner version.
Also make sure that you updated all files, not only EXE file.

I think you right, it's 13.12. Pasting ocl's from 14.7 in miner folder still works ?

I released two builds of v9.0: for Catalyst 13.12 and for Catalyst 14.x.
Just download miner for Catalyst 13.12 if you use Catalyst 13.12, it is about 1% faster than miner for Catalyst 14.x.

Hi Claymore, will there be a new version for Linux? The latest available is 7.0, which crashes for me after a day of hashing, sometimes it lasts 2 days, sometimes it crashes an hour after the start.. and I've got a 280x with Elpida chips in my linux box, so I suppose the newer version should also be faster than the current 7.0... not to mention the fee difference.

Yes I will release v9.0 for Linux in a few days.

[cacanin]

v9.0 is available:

- Improved speed by 5-15%, depends on card:
   About 810 h/s on stock 290X (Hynix memory).
   About 710 h/s on stock 290X (Elpida memory).
   About 690 h/s on stock 290  (Elpida memory).
   About 550 h/s on stock 280X (Hynix memory).
   About 440 h/s on stock 270X (Elpida memory).
   About 410 h/s on stock 270  (Elpida memory).  
- Reduced dev fee, now it is 2.5%.
- Improved "-li" option, Windows freezes even less.
- Best "-a" and "-h" values are set automatically for 290X,290,280X,270X,270,6950_2GB cards.

Note: For cards that are not in this list you need to check different "-a" and "-h" values to get max speed.

   Kasno Marko na Kosovo (oteto) stize !

Putin miner 1.3 way better for me on rigs with 280x ..i got 20% more coins on the pool compare to Claymore

Do you use Elpida  memory?

dont know..i have different 280x cards from ASUS and Saphire

Putin radi kao doxa a ovo djubre od Klejmora od mene vise nece dobiti jedan jedini ser pa taman nemao fee !

"Putin miner much better than claymore,i will never return to claymore again even without fee"

Izostavio si DJUBRE !

[E9800]

Very nice improvement.

My Results (Using the latest 14.9 AMD Drivers)
X3 270X went from around 1100 to 1280
X2 265X went from around 750 to 877
X3 290 went from around 1950 to 2150
X2 280X went from 1050 to 1150
1X 7750 went from 118 to 130
X2 290X went from 1550 to 1585

You need to release an Nvidia Miner. Keep up the good work.

my 5830 also have that problem..i go back to v8.0

i've seen low difficulty share error too when 280x temps are high or when overclocking is too much

great work btw, performances are increased

[UberMakedonische]

Finally i tested and this is the best miner so far. I have 290 Tri-x and i am getting around 750/h per card with both drivers 14.7 and 13.12. Thanks for this Claymore.

[antonio8]

I got my 270X uo to 450 h/s and I'll take that but I can't get my 280X past 445 for nothing.

It has the Elpida memory. I tried auto set, -a without the -h, -a with -h. Changed the -h from 832 (which it showed at beginning) 864 and 800. Nothing.

Runnung the 13.12 driver version on Windows 7. I can't down clock my core under 1,000 and have the memory at 1,575.
