I suspect it could possibly be a 5.5x multiplier and I don't want to

Not like you can though.

I've run my current PII Klamath 233 at 2x66, 3.5x66, 4x66, and 4.5x66.

If you can get a Klamath cheap, why not try it. They don't run exceptionally hot, but they are somewhat hotter than the Deschutes chips. I'd just get a CPU that has a cooler included to keep things simpler. There are a couple of different cartridge designs so you can't use late model Deschutes or Katmai coolers on Klamath or most Deschutes PIIs.

Sounds like it's best to stick with the 233 or 266 CPUs to make sure it's unlocked.

Hello,

I got a Klamath PII 233 and looking for a motherboard to achieve multipliers starting from 2x. Would be helpful to know which motherboard you used to achieve the above range of multipliers with this CPU. Thanks a lot!!

I have Chaintech 6BTA (same as 6BTM but with onboard audio) that has 2x multiplier and it can be set in BIOS. My 300 MHz Klamath worked at 2x66MHz but disabled L2 cache. Did not have time to test it further, will try other CPU's and multis in a week.
