RE: OT Computer Processors

["Matt Kummell" <kummell@xxxxxxx>]

On that topic - 266 Mhz DDR RAM and 133 Mhz SDRAM modules are not
compatible - there's a difference in the pin structure and notches on
the DIMM.  ...and you're right on the RAMBUS - P4 only, although the new
Intel controller chipset coming out later this year should support DDR
RAM with a P4. (trying t  position the P4 in the lower end market
requires Intel t  get away from the expensive RAMBUS option).

Can you tell I've been dealing with this a bit to  much recently?

Dan,

AFAIK a mobo for a P2 cannot accept a P3 I seem t  remember having t
upgrade the mobo when changing from P2 t  P3. Could be wrong though my
memory is cr4p at best!

Memory, there is 66, 100, 133, 266 and RAMBUS! On a P2 it's most likely
t  be a 66mhz front bus so that is the speed it will work at regardless
of what you put in, although RAMBUS is only used on P4's I think. Some
of the IT guru's in here probably know different :-) It should be okay
with a faster SDRAM but not a slower one than the BIOS says it will
accept, or at least it all has t  run at the same speed. I have built
several machines with different clock speeds in various SDRAM's but they
d  run at the lowest speed out of all the chips used.

HTH

Hi all

A couple of off topic (kind of PC questions)

I have a P2 266Mhgz machine - I want t  upgrade the process in this,
can I put in a P3 chip? - can anyone recommend somewhere t  buy new
processors from?

Also Memory wise it uses SDRAM - where can I find out what type I
need t  use t  add t  this, there seems t  be 2 main types, 100mhz
and 133mhz - will it make any difference if I use the wrong one!?

Thanks - as always there is a wealth of knowledge on this list, and
it seems rude t  go elsewhere!

Regards


Daniel
