PII-266 @ 266 (66x4) or Celeron 266 (no L2 Cache) at 400 (100x4)

A frind of mine wants to upgrade his son's PII - 266 to one of my celerons.
The choices are:

1) Celeron 266 (no L2 Cache) Runs fine at 400 (4x100)
2) Celeron 400 (with L2 Cache) only runs at 400 ( 6x66)
3) Celeron 366 (with L2 Cache) Runs fine at 550 (5.5x100)

I can not find a manuacturer or modle number so that I can get jumper settings for changing the Multiplier, but It is cleare to see how the bus speed is changed, so it looks like the Cely 266 is may be the only one that I can make work as the multiplier is already set to 4x.

Question: How will the CacheLess 266 running at 400 compair to the PII 266 in games?
 
Since Celerons are clock locked, multiplier is not an issue as the processor will ignore motherboard settings.

The best performance from the options is (3), the 366 running at 550MHz.

A Covington class Celeron running at 400MHz gives performance somewhere between a Pentium II 266 and Pentium II 300. It won't be much of an upgrade over a Pentium II 266.
 
You can't change the Multiplier on the newer Intel products, it's set by the processor, not the motherboard. What is the chipset of the motherboard (FX, LX, BX)--does it use 72 pin SIMMs or 168 pin DIMMs?? Are you sure it will support 100MHz bus speeds?? If it will Celeron 266@400 was a fine game set up it it's time. RRRRR

All settings are via jumpers, but I do not have the manual to tell me what the settings are.

<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Did I understand the the previous responses correctly, that the CPU will simply ignore the MoBo multiplier and run at it's internally set multiplier?</SPAN>

The multiplier is set internally by the processor.

The motherboard setting is irrelevant.
 
"The multiplier is set internally by the processor.
The motherboard setting is irrelevant."

So, if I install the Celeron 366 in this BX board, and make no change to the multiplier jumpers, (currently at 4x) will it automatically run at 5.5x?
 
Bump for clarification on this question from my previoues post:

It will either run at 5.5x, or not at all.

It should run (90%), but some motherboards (crap ones), just won't run(10%).
 
Choice 3 would be fastest, choice 2 second fastest. Another choice is overclocking your P2 266 to 300 using 100x3 (the P2 may not be locked).
