I have the same problem on my P5B dlx

this f ing board is driving me nuts

the ram does 500+ easily at 2:3, orthos and memtest stable for the 12 that I tested.
but 4:5 this $H| doesnt boot and sometimes if it manages to boot i get memory errors in windows
I have tried all bios even the 804 but no luck


this cant be a memory problem right ?

p.s my ram is rated for 500mhz
