I have ran this exact processor on my tyan trinity KT133 [S2390] motherboard for 7 years without any glitch, overheating, or slow down! It runs as great today as it did brand new..It is amazing how fast this processor is..It'll keep up with any of our 2 plus GHZ processors. I would LOVE to be able to find a new one someone just laid aside and forgot about..lol

The First and The Best CPU

Had one too! Never failed me, and was faster than some 1.7GHz CPU`s.

;)

On that machine, I could run four movies and one music playlist without any glitches!

slow with XP I must admit. I too impactient.

Not good at overclocking, but tweakable

Using the lead pen trick, this processor could be multiplier unlocked. On my motherboard, exploiting the trick made computer reboots delicate (I needed a complete power cycle), but performance was the result. I mean:

- base clock is 100 MHz, multiplier is 9.5; reduce the multiplier, and the CPU can reach slightly under 1 GHz with 7.5x133, with no problem - but much higher (+33%) memory bandwidth: +10% performance for RAM, +5% performance for CPU O/C

- with a DDR chipset (say, Via KT233a) and good timings, this meant that you could sync the CPU's bus with the highest supported RAM clock: +20% performance

- with quality DDR RAM, you could lower timings quite a bit: +2% performance

With these 3 points used (lower multiplier, slight overclock, much better RAM access), performance could increase by as much as 40%! Yes, I know, it seems a bit much... But then, I ran extensive Aquamark3 tests to be sure, and there it was.

Now, apps that ran in the CPU's cache didn't get much of an improvement; but with 64k of cache, the CPU spent its time waiting on the RAM. Improving RAM access as much as you could was, indeed, key.

For me, it meant going from unable to start to playing Doom 3 not too badly on that CPU.
