SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[thenextdinosaur]

forget about cn-gpu crap. It is much better on nvidia. And will be easy for fpga/asic if have any volume

I agree and tend to believe in the same thing. I removed CN-GPU from my list.
About the temperatures, what other AMD Vega miners are experiencing? Sometimes I think HBM at 75°C might be too hot, although it doesn't throttle at all.

Yup. it's much better on Nvidia but floating point math is not efficient on FPGAs and ASICs.

When is cn/wow implementation expected to be done?

hi dok!
heavyx ready?

Are you joking? I've read about fpgas doing scientific floating points math years ago )) It is what they are designed for ))

never said they can't do. read; efficiency.

EDIT:  new FPGAs do come with loads of DSP blocks so perhaps that gap is quite narrow now.

I can't tell exactly, but new version will be released in max 10 days, all  new algos added.

I never trust one source but on paper fp math is slower on FPGAs unless they have lots of DSP slices.  
Now that's the question how many is available and for how much.  Efficiency wise they would be order of magnitude better than GPUs.

I got a source that mentions on the FPGAs capable of doing 10 TFLOPs but looks pretty expensive.  10 TFLOPs is what an RTX 2080 does.

and a 280K cell FPGA is priced at $7.5k

One issue that I've been getting since earlier versions is that, while mining on a pool with multi-algo support (MO), sometimes the miner will just close without any apparent reason. The command prompt window just closes. When checking the log, nothing abnormal was happening. Sometimes the last line on the log is an algo change, sometimes is submitting a share. Miner just closes. Any idea of what may cause that or what else can I do to test more and provide more feedback?

[doktor83]

I know about this issue, and i probably fixed it (khm, i really hope), so it will be available in the next version soon.

I was having the same issue without using profit switching, just a single coin.  Tracked the problem down to the AMD driver crashing.  The only solution I found was to lower the intensity setting by 10-20%.  Yes, you get a lower hash rate, but the program doesn’t crash either.

This is different, yes driver can crash if you push the cards too much, that can happen with any miner.
Also try to lower memory clock or give the gpu a little bit more voltage to the core, and maybe you wont have to lower the intensity at all.

[t0lsty]

one of vega`s rig gives me such error after 10-20 minutes :

"Pool rejected result 0x000xxxx  (invalid job id) "

when I lower the intensity  - it works few hours, but then again this error.

it`s on turtle algo. but have same on stellite with newer srb

Whan can be a problem ??

What about hashrate on Vega56@64, RX580 4GB and RX570 4GB on CNGPU algo ?

You are probably using xmr stak settings here. well don't. Try out auto setup.
