AMD K5 overclock

**richardtdy** · March 17th, 2003, 07:40 AM

First timer, so be nice! Anyway, I have an AMD K5 P100 and would like to overclock the craop out of it. It's a home built on a P5V30-B4 mb. If I have it set per the manual, the ratio is 1.5, 66MHz, 3.3V. It gives me the option to go as high as ratio 3.0, but only 3.52V. If I max out the settings, and it still works!, how fast might I expect it to be?

I have a new one coming and just want to play around a bit while I wait!

Greetings,
A simple formula:
CPU Clock speed = Front Side bus X Multiplier.

Currently you're cpu is running at 66mhz X 1.5 = 100mhz
If you change to a multiplier of 3 and multiply by the FSB of 66mhz you get 200mhz (approx.). I doubt ver much it will get there tho'. 66 x 2 might work giving you 133mhz.
Regards,
Elad.

would increasing the voltage help anything?

Only to a certain point, But I have 2 K6-2 450's and they won't overclock at all, I can't even get another 1Mhz outta them, one will not boot If I run it at 2.4v (go figure that's what is says on the chip)

The voltage on those chips at 3.3v means anything beyond 3.4v will just be adding heat and not that much for stability. increasing it to the max on that board may also cause problems.

With those it's better to slowly increase the multiplier until it's not stable, then increase the voltage and see if it becomes stable, if it does, then try another step, if it's unstable then back it off by a setting, If you FSB supports 75Mhz this may also be an option.

i think 66 x 2 = 132...

Don't be a doubting Thomas Eladijaz.
Here's an AMD K5 P75 running at 200Mhz. A P100 might even have a better chance of getting there.

But I wouldn't hold my breath richard.

And, yes increasing the voltage can help the overclock. Usually you want to attempt to increase the speed first, then if it's not stable or won't boot up then start increasing the voltage.

WOW, Outpatient! That's a really big leap! Any tricks you used to get there? I'm going to get off work in an hour and go home and play!!

Well Golly Gosh and Bless my Soul Mr Outpatient, there is a sight for sore eyes - and as the man said "overclock the craop out of it" - let nothing hold thee from thy purpose richardty!!!
