Different computer and a Vega 64 instead of a Radeon VII, same problem using v.7.2. Raising the fft size to 6.5M avoids the problem but running at 2730µ/iter instead of 2020µ.

Restarting with -fft - 6.5M works.

New gpu rig with excelent price/performance

I am glad I cancelled my RTX 3080 order. It really disappoints with 1990µsec/it for a 77M exponent. I acguired a Radeon Vega 64 a few days ago at 240 € and I get 1970µsec/it for a 109M exponent....

Let us assume 1700 Mhz. That is the boost frequency of the Nvidia's FE card and factory overclocked cards from Gigabyte and others go only marginally higher (1725 Mhz). Where do we get then?
