Speedstep question

How, or maybe where, is speedstep implemented? I ask this because I've been looking to upgrade my 770x to a PIII processor. While doing this I've updated my friends T20 processor and happened to compare the specsheet (from the tawbook and twbook) and noted that virtually everything is identical between the T20 and 770x (same chipset, same super I/O controller, same bus speed (when running a PIII) and I know that speedstep drivers are contained in WinXP. So is it implemented in the bios or

You might want to read
this thread. All the 770 gurus are there.

Thanks, I'm a part of that thread. I realize the 770 is limited to a non-speedstep CPU, I just want to know why and how speedstep works. More curiousity than anything else.

What about
Intel's SpeedStep website? There is also a nice
datasheet.

That's what I was looking for, Thanks. It needs a speedstep enabled bios and voltage regulator.

Neither of which is available on any 770 motherboard to my knowledge.
But, I'll be putting a non-speedstep PIII 500MHz in a 770Z later this week.
Film at eleven!

I'll be interested to hear how that goes. As a side note, I've been doing some maintenance on my friends A20m and couldn't help but note how much quicker in WinXP it is than my 770x PII 400. You seem to have used virtually every thinkpad ever made
Would you say that is due to the ATI vid chip over the old trident 9397, the Celeron 500 being that much faster than the PII 400 or the fact that I was running at 1280x1024 and his machine was at 1024x768?
Keep in mind my machine has 320Mb and his has 128Mb and it was still considerably faster. When I would click control panel for instance, it would take 5-7 seconds and the hard drive would spin before it came up on my machine whereas on his it was almost instantaneous.... think the PIII 500 upgrade would make this comparable or faster?

A bit yes...but you may notice a VERY noticeable increase in speed if put in a faster hard drive....

918 mghz is possible with 850 speedstep cpu hardwire mod and fsb hardwire mod,700 mghz max with no mods utilising the same cpu but unmodded.
a decent hardrive makes any pc go like the clappers even moreso.
