Not sure what I mean by 4K / 2K refresh either. I have been to several &nbsp;sites and 4K refresh seems to be about half the price of 2K refresh. But they all warn check your user manual for compatability.

Oldgreyguy directed you to the right place there. &nbsp;Crucial do your motherboard compatability bit for you - they keep a database of motherboards and compatable memory.

I have a old Sony PCV90 computer and I want to upgrade the memory from 32mb to 128mb. It has a AG430HX motherboard. I will use 4 new 32mb EDO SIMM's 72-pin 60ns. Can someone tell me if I can use 4k refresh modules or do I need 2k refresh modules?
