Okay guys,
I've been into a bit of overclocking for a while, and never did manage to get that damn pencil trick to work, but when i replaced my duron 1200 with a 2600 (FSB=333) and the gigabyte 7vaxp ultra, wierdness started to happen.
The system itself doesn't seem to stable if you increase the FSB above 170 but I found out buy accident that the board had set the cpu multiplier wrongly with the multiplier jumpers on auto.
To my suprise I found that I was able to pick whatever multiplier I wanted. Normally it's 12.5x, but it boots fine at 13x(bios reports it is a 2700 and it runs completely stable), is semi-stable at 13.5x(bios says 2800) and almost boots at 14x. The stability problems lie, i suspect with noise rather than heat as the system shuts down soon after boot-up.
My question here is...
Is this normal behaviour for this board (revision f4 or something) or have i stumbled across a magic thoroughbread processor which isn't multiplier locked?
I inspected the chip several times and there is no evidence of prior tampering on the bridges.
AMD 2600+ (fsb 333)
gigabyte 7vaxp ultra
512 pc2700 ddr
leadtek geforceti 4800
and some other stuff
BIOS is version f4 or something
