Athlon 500 0,25 micron

[Parry]

I have (sigh!) a first athlon 500 mhz 0,25 micron motherboard biostar m7mka that not support the new thunderbird. How i can overclock it!
Please help me!

As an easy way of doing it - you can acquire a "Free-Speed" add on board that clips into the top of your chip and unlocks the multiplier.

However - the very first Athlons were a very fickle die that wasn't all too rampable in every case. If you can imagine on a similar playing field that Intel's 0.25 process had great difficulty in being pushed past 650Mhz by overclockers.

If you do however have a chip that will go all the way with an add in board - you can expect about 850 - 900Mhz easily provided you have sufficient cooling and the cache underclocked to run at a ratio of around 1/3 or 2/5 of the core speed. The add in cards really are a good buy for Slot A processors.

The rampable 500's had a 650Mhz core anyway - it was quite well publicised on the tech sites at the time.

Good luck anyway and HAPPY NEW YEAR

I have one too, a week 42 with a 650 core / 3.3ns cache. I used a GFD (gold finger device), the TD2 (tweaking device 2) which uses no powercord. I now run 750 aircooled (GORB) on 1.7V. These processors are GREAT!! So don't be sad and get yourself a GFD! Chech your week number/ CPU database, the newer they are, the better they OC (in most cases!)

p.s. I run standard cache speed = 1/2 clock
