A little 15min prime. I have to explore the x20 and x22 multi too before deciding the final setup and final 24/7 stability test.
This seams to be pretty stable, and a really good candidate for 24/7 use.
The next BCLK, 221x19 seams to be stable too, but it needs 1.328v vCore which adds 3'C to core-temp, so this is the sweetest spot for 19x.
