Hey guys,
I'm trying to undervolt my CECHL. Used 50/51 adresses to set the values out of the mullion table like said in a nother thread on psx place. So far so good. But I can't find any tutorial how to fix csum on sw. It looks completly different to mullion ps3s. See attached foto. There are no "should be" or fe39 or so.
I switched the value for 51.
EDIT 3.0:
I undervolted my CECHL04 it now bearly reaches 50°C. It maxes at 48/48 in TLOU.
to undervolt a CECHL it is a SW Syscon you need adresses 0x50 and 0x51 and use the MULLION VID table despite its a SW system.
to fix the checksum missmatch type in "eepcsum" after that type that value given endian byte swaped in adress 0x7FE so like "w 7fe xx xx". then your ps3 boots up again.
F.ex. eepcsum results in csum = 0xB883 you have to type in " w 7fe 83 b8". reboot console, done. ps3 boots again. this only counts for CECHL VER-001 boards. I don't know if the csum adress is the same with other SW revision. I'll have to find out. and do not forget to use the mullin VID table despite it is a SW ps3. it depands on the used buck controller not on the syscon revision wich table is to be used.
Edit 4.0:
I finally undervolted my super slim 28nm version. All I said for CECHL counts for her to BUT you have to use the SW VID table.
So I can sum up all fat ps3's despite it has sw or mullion syscon need to be downvolted with the hex values out of the mullion table. Starting with the slim 2500 and later you have to use the sw vid table.
