NetServer 5/100 LS CPU upgrade

[Axel_cpu]

Hallo,
I'll upgrade my NetServer.
Now it's a Pentium 166Mhz with MMX but my NetServer see 133Mhz with MMX.

What I can make to 166Mhz MMX was true 166Mhz MMX?
or - what I can in this NetServer put (maximum)

Did you upgrade th CPU on the old card?
Or did you buy a 166mhz board from some place like ebay?
I had a LS/100 that I upgraded from 100mhz to Quad 166.
Only things I had to do was add a DC-DC Power Unit above the Power supply
Remove the old CPU card and install the NEW CPU's Cards.
Ran NETSERVER navagator CD.

That was it.
If you got the board off ebay or somthing like that what is the Part Number on the board. If someone plugs in a 166 CPU in to a 133 board it will only run
at 133mhz.

Thanks

- Yes. P166MMX work now on the old CPU card, but work at 133Mhz, MMX instructions are detected by many programs in OS.

Now I understand that I need NEW CPU card.

Isn't possible to change on the OLD Cpu card multiplier factor or Fsb ???

i WISH I know where the jumpers where on the CPU board, but HP does not
tell us users where they are and what combo to use for different CPU. Maybe if I had a 100mhz, 133mhz and a 166mhz I could look them over and see where there different. Maybe even find a setting for a faster CPU like a 266mhz.

But, I know of no one that know where jumpers are on the CPU card.
That info is somewhere in HP marked TOP SECRET.

If the CPU card detected different processor at different speed than original, this card have somewhere auto detecting CPU.

I have a question
what is the Fsb and multiplier on my processor?
Programs like WCPUid in OS don't tell mi that.

Near the CPU is some chip - this chip determined Fsb? If yes - that Fsb is fixed and = 66Mhz.
CPU Speed is determined only by the variable multiplier factor.
Maximum multiplier on standard CPU card = 2x (2x66=133Mhz).
I think that multiplier factor is determined by J3 on the CPU card, but I don't confident.

Maybe who know more about this and know how this set.
