Overclocking Duron 1.3

[jazzboy]

Hi all,

I have a fairly old computer with a Duron 1.3 in it and was looking to overclock it to hopefully give it a bit more life. The trouble is that the motherboard doesn't have a PCI/AGP lock and I'd rather not take pci/agp speeds out of spec.

However, the motherboard does support 133 and 166 bus speeds, and I was wondering whther I might be able to just set the bus speed to 133, therefore taking the cpu to 1.73Ghz. The motherboard overvolts a little (1.80v - default 1.75).

Is this asking too much?

I tried searching around the internet and couldn't really find much about overclicking this cpu. No big deal if not possible.

Thanks in advance.

If it is a thoroughbred (B)core you should be able to make it to 2000-2200MHz relatively easily.

T-bred (A) will probably only get 1800MHz or so. (not many of these were made)

If it is a palomino core I doubt you will reach 1500MHz.

This is none of those. Its a Morgan core.

A Morgan core is the duron version of the Palomino (.18 micron) with aluminum interconnects and only 64K L2 cache.

Doesn't look like much headroom for overclocking.

OK cheers.

But of a bummer but nevermind.

the GA-7VAXP rev 1.0 or higher won't allow a 166(333)fsb for any 133(266)fsb CPU's, the most it will allow is 165mhz which puts the AGP/PCI around 75/41mhz IIRC...I believe the processor can be modified to default to a 166fsb but I'm not sure how to do this.
I believe that the GA-7VAXP can be modified to allow a 166fsb(for 133fsb cpu) how ever this requirers soldering of the two contacts inside the silkscreen next to the FSB jumper switch. this should make the bios default to 166fsb...however it is permanent so I never attempted this with my 7VAXP
