getting a 4200+ X2 to work?

[DFI_nub]

ok guys got my 4200+ x2 today, n tbh im having a bit of . with the thing,

 

where do i start, the cpu stepping is : LDBFE 0619 XPMW

 

i put the cpu in, all stock speed n reset the cmos to defaults, i changed few ram settings incresed voltage to y bh-5 etc etc sorted timings, loaded windows, got onto the sign on screen and moved my mouse it completely froze, after 2 n half hours of fiddling i have jsut got into windows with alot of hard work, i have connected all teh power cablesto teh mobo,

 

BTW did i mention, that to get it to boot into windows without hanging, i had to lower the cpu multi to 10x from 1x windows started imediatlly, if i leave the multi set to auto (11xs) it loads windows freezes and come up with a bsod now before windows even loads tbh i think it takes the F*cking piss, the bsod is: machine_check_exception

 

 

its winding em up and now i really dont know what i can do i darnt restart my pc atm just incase i never get back into windows

 

 

if anyone can help please do

Have you tested your machine with memtest86+? If not enable the option in the bios and run 20 passes of test 3 and 10 passes of test 8.
