CAS2 DDR SODIMM - Does it exist?

I just got a new notebook that supports PC2700, so I'm about ready to swap out my PC2100 SODIMM's for some new ones. I was hoping to find a couple 512MB sticks that are rated CAS2 (2-2-2 or 2-3-3) @ DDR333, but I am having trouble finding any. Supposedly Kingmax was putting 5ns chips on their PC2700 product, but that doesn't seem to be the case anymore.

Should I spend the extra $10 per stick and get something rated at PC3200? Will the SPD be likely to report CAS2 - or at least lower latencies generally - if I get this higer speed stuff? As far as I can tell, I have no way to "force" my notebook to use faster latencies, so they have be programed into the SPD...

Thanks,
A
 
I haven't seen any "enthusiast" SODIMM modules, probably because most/all notebooks lack BIOS options to take advantage of better/faster RAM. PC3200 would probably be the JEDEC standard of CAS3, so running it underclocked at PC2700 levels would probably only drop it to CAS2.5, also the JEDEC standard. I'd say don't worry about it.

BTW, so your notebook came with PC2100 modules? What capacity? I'm in the market for some 512MB or 1GB PC2100 SODIMM modules. If you are swapping out your RAM and the old modules are at least 512MB each, I'd be interested. Have Paypal, will travel.😉
 
underclocking and lowering the CAS isn't an option since i doubt his bios will allow him to do so. the closest i saw to enthusiast ram was the Geil golden dragon chips stuck on a SODIMM. not sure what its timings were.
