I'm looking to buy a 1.2GHz T-bird and would like to know if I should buy standard PC133 or CAS2 ? Is there a big difference between those two types ? And please don't tell me to get DDR cause it's still listed at 300$ U.S here in Canada. If ever the price drop manages to find it's way here, which mobo would you recommend me ? Thanks for any help !

Well standard PC133 has CAS 3 and CAS 2 could mean faster access to the memory. Go for CAS 2

This site is cool.

The difference is a small - a very small - performance difference. If the price of CAS2 isn't too much above CAS3, go for CAS2.

Sidenote: You'd probably be able to find DDR memory at crucial.com for a pretty good price though.

Actually, DDR (of the PC2100 variety) is out for $103.50 per 256 MB at http://www.crucial.com. About the same as non-DDR. I just ordered myself 512 MB.

As far as your question goes, CAS is the latency, which stands for the amount of time it takes your memory to respond to a command. CAS2 means two CPU cycles, CAS3 means three CPU cycles. Obviously, CAS2 is better.

I've heard that there could be some compatibility problems with this type of memory (CAS2). Does any of you ever heard that ?

Here's what I'm looking to buy:
- AMD Thunderbird 1.2GHz
- A7V133 motherboard (VIA KT133A) (can't get a nice AMD760 chipset)
- OEM PC133 (CAS3 or CAS2) (can't find a mobo that supports DDR and AGP Pro)
- Asus GeForce2 GTS 32 MB
- 350 W PSU
- Maxtor DiamondMax+ 40 GB

Is the CAS2 going to make a difference that worths 20 bucks ? Thanks again for any help

It's a $5 difference at crucial.com which I think is worth it and their memory has a good reputation.

I don't think the difference between CAS2 and CAS3 memory is big enough to be noticeable in everyday use. It's nice to have a faster responding memory for demanding applications, though. And I haven't heard about any compatibility problems based on CAS (but someone else might have heard more than me).

So, it depends on what you want. On the other hand, $20 might also be considered not noticeable in everyday use by certain people. Again, the info is out there for you (you might want to consult the crucial.com's FAQ for more), but the decision is yours.
