SDRAM Memory: different speed, is it OK?

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?

If it’s stable dont worry, PC2700 is backwards compatible with PC2100.

looks fine, the new memory is running underclocked to match the old

“2.5-3-3-6”

wait states, lower is faster

brain surgery/rocket science

If I replace the old memory with another PC2700, will I gain an increase of performance?

Does it means my new memory (2.5-3-3-7) is slower?
Thanks for all your replies

Thanks. How do I know if they are stable? Sorry if its covered before.

  2. no the new memory is faster, it’s running underclocked to match the old
