I applied the firmware update, then removed the reg changes with https://gist.github.com/nissel/a20a6ca5f8aeb8802554f239a28833bd then rebooted
But they aren't going to interact in any strange way, the firmware patch appears to just limit the buffer to 64MB so fixes the issue in exactly the same way.
I wouldn't want to install a firmware update in a system that's crashing randomly, as if it did crash during the update that would probably be very bad. So id say it's best to leave the reg changes there until you update the firmware.
Well I wouldn't install an update on a system that could shut down at any moment either :). If you modify the registry, the changes are applied only after a reboot. But I'll do as you said anyway. Thanks!
Anyone know what these values should be for an sn550 drive? I've also been affected by BSOD but no firmware update. New HWinfo update reports 200mb hmb even if it set all variables.

Just try to disable HMB, setting the limit didn't help me initially either, although I have an SN770

check the device manager
Thanks, value that worked for the sn550 if anyone else is interested is:
