PC133 on my 600E?

I have a chance to buy one or two PC133 SODIMMs - both 128MBs.

I have contacted the seller and he's informed me that each SODIMM has 8 chips in total (4 each side).
One SODIMM is a Hynix brand and the other a Hyundai.

Can anyone suggest whether they 'may' work on my Thinkpad 600E?
(Are they single-density?).

I may get back to the seller and ask him for exact part numbers for the SODIMMs to be sure, but i'd also welcome any comments from this forum.

I currently have two 64MB PC100 SODIMMs and would like to simply upgrade one of them so the new PC133 would be running alongside the remaining PC100.

Thanks.

PS The SODIMMs are going for a tenner each so if i buy one and it doesn't work then it's no great problem!

Yes they 'may' work.

I'd think it quite likely but I'm not 100% sure on those specific parts. My ol'600e was fine with pc133.

Well i have the SODIMM part numbers.

PC133U-333-542
HYM71V16M635HCLT6-H AA
HYM71V16M635ALT6-H AA

128 MB Sync 133Mhz CL3

Searches on Google give endless pages of endless data and no easy way for me to see the SODIMMs specs.

What do forum members think?
Should i risk buying one or both SODIMMs?

Thanks.

I tried a 256 8 chip PC-133 in my 600E and windows woulden't take it, it kept restarting , at the start mode selection.

A 256MB module with 8 chips would be high-density memory, whereas a 256MB chip with 16 chips in total would be low-density and (hopefully) 600E compatible.

I have the chance to get one or two 128MB modules and each module has eight chips - 4 on each side.
Does it scale down so a 128MB 8 chip module is going to be low-density and 600E compatible?

Nope, has to have 16 chips.

Well i've decided not to buy either of the PC133 SODIMMs.

Other than trying to establish whether they are single or double density i was also warned that they may not be compatible with CAS latency 2 - required by my Thinkpad.

Better not waste any more time on these - shall be looking for some PC100 modules that will work.
