I found that is taking time with this function call: m_queue[0].finish(); in line 966 of CLMiner.cpp

It happen in both 5700 modified to 5700XT, in the 5700 XT are mining perfectly… that didn't happen before with drivers 19.30

Hi. Which kernels do you use for the 5700?

Hi. Which kernels do you use for the 5700?

I use the OpenCL standard, there aren't premade kernels for 5700. I suppose it has to be something also with drivers but it only happen in 20.30 and not in 19.30...

[BoriZka67]

How much Mh does 5700 and 5700xt give You? I think I need to compile the kernel, because other programs give me stable 55Mh

The 5700XT 51Mhs the 5700 modded 0Mhs, they don't work with 20.30 or 20.40

А что модифицировали? у меня 5700ХТ и 5700 дают примерно одинаковый результат. Драйвера последние от 22.09.2020. Хочу вернуться на ethminer, но пока не соберут ядро под эти видеокарты приходится сидеть на TRM((( (у меня для сборки ядра нет ни опыта, ни люнукса)

Related to #2079 now I am seeing .08 for my 4GB RX570. Any ideas what is happening?
