Does the number of pins matter for a stick a ram? i.e. I have a stick of 256mb PC2100 ram 184pin, but when I look on crucial it says I need 200-pin SODIMM DDR PC2100. What I want to know is if I can still use it for that since it's PC2100??? Any help would be greatly appreciated!
Got a tip for us?

Ummm, yeah, it's kinda important how many pins it has, otherwise it's not gonna fit...jayeskreezy said:
It would help a measure if you told us what kind of machine you have
it's a laptop...I looked on crucial.com though for it...it's an ibm thinkpad r40 2681 series...i had two extra brand new memory sticks layin around the house today b/c i just realized that I purchased the wrong one so I was wondering if I could put it to good use on at least one of the computers here
OK, a bit OT for a Mac board, but the R40 needs PC2100 SODIMMs, 200 pin.
The 184 pin sticks you have are DIMMs.
SODIMM means Small Outline Dual Inline Memory Module - it's a different size package than a DIMM.
Don't be deceived that they are both PC2100 RAM -- that's just a speed rating. It's like saying "these tires are radials, so they should fit my car" - depends on the wheel diameter, width, profile, all that.
There are lot more factors than just PC2100 that have to be accounted for.

This RAM can fit in a 1 GHz G4 iBook?

Yes it will fit. Will it work? Nobody knows. Corsair does not recommend or guarantee this model RAM for use in an iBook.
I recommend (especially for new Mac owners) that you choose RAM from a reputable vendor who tests and guarantees compatibility with your model Macintosh, and offers a lifetime warranty and a no-cost return if it doesn;t work.
Outpost/Fry's, NewEgg et al. do not guarantee compatibility, and are a poor choice for mail ordering from Canada, Cooper. Besides the additional shipping cost, you will have customs brokerage cost of $8 to $16, 1.26 exchange rate on your credit card and GST and TVQ. Then if you have to send it back you'll be out the shipping again.

sorry to be OT in this thread, but as it's about RAM pins i'll post. i know that desktop ddr and ddr2 have different pins (184 vs 240) but since both laptop ddr and ddr2 have 200 pins can you use ddr2 in a laptop that needs ddr? sorry if its a really stupid question
thanks. ive never tried to do that or anything <mischevious smiley> but was just curiousCanadaRAM said:
