DragonFly crash over Vaio NR21Z

[dark0s Optik]

I 'd like to install DragonFly 1.12.1 on my Sony Vaio NR21Z, but
whilst DragonFly load, it appears:

RAM parity error, likely hardware failure

Fatal trap 19: non-maskable interrupt trap while in kernel mode
instruction pointer  = 0x8:0xc04a7750
stack pointer         = 0x10:0xc07789e4

kernel: type 19 trap, code=0
Stopped at        DODELAY+0x1:       movl   %esp,ebp

What is the problem, DragonFly don't support my notebook
