Yes, same problem with F8.
I just downloaded the calculator, but I'll need to find the values to plug in. Pity it can't auto-load them. However, I'm using vanilla XMP Profile 1 without any additional tweaking beyond that (and the same problem occurs with default 2133 MHz timings anyway, so it's definitely not an overclock problem). Memtest86 passes with zero errors on a full run. The only
symptom I have is the fail during sleep.
