you try having AFUDOS loaded onto a bootable USB?
I fixed a P5B-DLX a while back with this issue.. wasnt fun, but used a DOS based flash program. Just depends on how bad/ly borked your BIOS is now...
if you have a removable BIOS chip.. just order a new one.
overclocking SB... this thread is already tooo long :p
set CPU multi for all cores or 4x core active
**sounds like the multi is only applying for single threaded apps... and as soon as stress testing all threads, its using stock multi still...
^^That is NOT heat throttle
i RE'd your PM. :)
**For CPU only OC.. you only need to change -> CPU vcore and CPU multi (cache voltages need tweaking for high OC)
For NB OC.. you need to increase Ring voltage and Ring multi
For RAM OC.. you need to change RAM voltage, as well as tweak I/O voltages based on RAM latency/mhz
