The first one seems to be PC133 SDRAM that's rated at CAS latency 3 at 133MHz. The memory chips appear to be rated at a 7.5ns clock period, which is normal for PC133 SDRAM. I can't tell the manufacturer/brand from the markings. As for the 128MB one, its obviously a PC100 module and appears to be rated at an 8ns clock period, which is normal for PC100 SDRAM. The manufacturer is unknown to me too.

The second stick, the 128MB, can be run at PC100 CAS 2.

What excatly is the difference between CAS2 and CAS3? What does CAS mean?

 

[Dark4ng3l]

cas2 is faster and I think CAS means colomn acces strobe

 

[radarnbo]

Is CAS2 noticably faster or is it such a small difference that no one really notices?
