Will a PC133 cl2 work on a PC100 mobo?

[Jean]

Greetings:

I am about to purchase 2 sticks of 256MB SDRAM PC133 CL2 from Crucial and am wondering if it will work on a PC100 mobo. If so, will it work at CL2 or CL3. Any insight thoughts would be greatly appreciated.

Yes, however it will only run at 100mhz in synch w/ others

 

[Adul]

it will run at 100 Mhz at CL2

Not all motherboaeds
I got 3 BX mobos that will not take PC133 RAM
Depends also on the manufactorer.
Check their website to see if their 133 RAM works at 100

yes,
but a PC133 single side 256MB or PC133 double side with cheapy 32x4 type chips won't.

the bx and i810 won't take 256mbit chips, but thats about the only limitation.

 

[Kingofcomputer]

you miss the 32Mbitx4 type chips, it's also 128Mbit, but BX/810/815 can't take this type of 128Mbit chips.

Thank you all for your comments and help. I will give Crucial PC133 CL2 a shot. It it doesn't work I am still be able to exchange for PC100. 🙂

Depends on the board, but I have a really crappy off brand BX board and PC133 works just fine.

if you buy thru Crucial's memory selector, they guarantee to give you the right one.

PC133 is fully backwards compatible down too PC66 I believe.

Not anymore. Several manufacturers no longer make the backwards compatible stuff since it is cheaper not to.

Any PC133 memory is backward compitable to PC66.
It's the chips it used is not backward compitable on the old motherboards using old chipsets.

Crucial's PC133 memory uses traditional safe choice chips, works in any motherboards or any chipsets.
