thank you, rayik
this is my 1st experience with abit mobo, i thought the setting is hidden somewhere in the bios or need to adjust the jumper to specific position to enable it
just found out that it wasn't my ram that caused my system to crash when multitasked (prime95 torture test, download files, watched movies) but it was my cpu
my celeron 1.1a maxed out @ 1.58G with default voltage
bought this new system last 2 days
thank you again
