some weird things on this computer's BIOS

1) CTRL-P for intel Me post message:
this only occurs during POST when dimm1 and/or dimm2 are populated. this is Intel Management Engine used for enterprise IT to configure and track assets. anyone know how to disable this, or will it affect performance? I would like to populate all 4 dimm slots on this board and the PC seems to be slower (dual channel) than when same RAM is placed in slots 3+4 (single channel)

2) intel speed step under CPU features- EIST enable/disable:
should I disable speed step or leave it on I want Max performance, IE processor never to slow down

anyone have any experience with these items?
thanks,
JGS
