PE> Computer Market has an article on RAM. And apparenly there is SDRAM ram,
PE> which is 20-30% more expensive, but it will run at the same speed as the CP

You are comprehensively mangling a whole raft of issues here.

In normal machine use, the speed of actual work is determined by the speed
of the CACHE, not the main memory. Thats the whole point of having a cache.

And in a Pentium class system you actually have three of those,
2*8K inside the cpu itself, the L1 cache, one in each of the code
and data pipelines, and then there is the L2 cache on the motherboard.
Normally 512K class size in a Pentium system.

So the short story is that those figures above are only part of the story.

PE> In my case, this is 100Mhz (with a Cyrix) rather than 66Mhz (even with EDO)

This is so mangled its makes no sense at all. The 100Hz isnt even available
outside the cpu at all, so no ram on the motherboard can be running at that.

PE> This is a 50% increase in performance!

Nope, its all comprehensively fucked up.

PE> How come no-one mentioned this?

Its just one of the rarer approaches used, and your motherboard
needs to be designed that way. Its not just a type of SIMM you
can choose to buy and plug in to any old Pentium motherboard.

You have managed to remember thats true of EDO too havent you ?
The motherboard has to support EDO ram or you will just get the
SAME performance as non EDO ram after paying more for the SIMMs.

PE> Should I get 32 meg of this stuff instead of 64 meg of other?

Nope, if the motherboard you plan to get doesnt support it,
you cant. They presumably would have mentioned that if it did.

And even then, depending on how you want to use it, more
ram may well be a better route than faster half as much.
