Is my SDRAM PC-100 compatible ?

[silizium]

I have an PII @ 266 mHz with 2X 32mb SDRAM. I don't know if it's 66mHz or 100mHz SDRAM. I want to know because I want to change my CPU, and faster CPUs use 100mHz bus...

This is what's written on the ram stick:
(AZEN RAM)

On the sticker:
AAP1182
32LDM-64G-10SYEP 3V4
32MB*168P*4CLOCK 07912

On one chip:
NEC Singapore
D4516821G5
-A12-7JF
9725LEA95 (this number changes from chip to chip)

On the stick itself:
94V-0
2/4M72SV18168PVV

On the stick, opposite side:
DS23M648

On the invoice, it's writteh only this:
RAM-SDRAM4X64
MEMOIRE SDRAM (32MB) 168P

On the stick, there is 8 chips per side, so a total of 16 chips per stick...

Thank you if you can tell me what's my SDRAM type!
