56 of 64 CUs are active. HW locks: 8 (R/W) / SW locks: 0 (R/W).
8 CU's are disabled by HW lock, override is possible at your own risk.
seeing as 4 low nor 4 high will provide you with an usable unlock you will have to do what steffoon did to get an useful unlock as quoted below you could also try all on an whim and hope that it works

From this info SE2 appears to be messed up on CU 2 and 3. I tried a complete unlock (as if...) but got artifacts all over the place. Normally I would stop but since some had luck doing a full unlock with disabled CU outside the last 2 I decided not to give up yet.
I slightly modified the python script to be able to unlock different CU than the lowest 2 and get the following result without any issues so far:
The small modification is on line 318 of the python script to allow the bit value of the CU columns you want unlocked. Anyone with a basic knowledge of bit manipulation can unlock additional columns this way.
In the end I'm happy that I got a partial unlock but I still find it strange why some apparently random units which appear to be working fine are locked. Anyone with an explanation?
You can't just unlock any which CU you want. You have to unlock at least four. You can't unlock one, two or three. You HAVE to unlock four. Due to the way the core is designed it has to remain symmetrical. You can unlock less than four. But you won't get any performance benefit as the core will bypass the unlocked odd CU's in order to remain symmetrical. So if you can't unlock at least four. Then don't bother wasting yer time. And unlocking two from one SE and only one from the others won't work either simply because now the SE's are not symmetrical. So yeah. Not gonna work.
