I just bought a 512MB Kingston PC2700 DDR SDRAM for my IBM laptop T40, from Bestbuy onsale for $49.
From Everest Home Edition screenshot, it turns out that the original installed memory is Hyundai PC2100 DDR SDRAM.
What do you expert think about this, is it OK? I don’t really understand what the meanings of 2.5-3-3-6@133Mhz etc thingy. Any advise?
