Memory clock back

Will ddr4200s 200pin 533mhz clock back to ddr2700 166mhz?

Try it if you can do it in BIOS, then if not you will have to reset it or use Default settings

Thank you for your quick response. Where do I look in BIOS, and if it is to set the "mhz" will this affect the existing ddr2700?

It should not damage the memory as it running slower not fast than its made to go. Depending on your BIOS you will need to poke around for settings if there are any

DDR2 4200 is quad pumped from 133Mhz, so it is running at 133Mhz X 4.

DDR1 2700 is dual pumped from 166Mhz to run at 166Mhz X 2. Which is 333Mhz.

Apart from them being different types of ram, DDR2 and DDR1. The 166Mhz will be faster than the DDR2 4200 can run at, which is 133Mhz.

Thank you; that settles it. I checked again and yes it is ddr24200. It was spare from a laptop I had upgraded, and I was hoping it would go in my friend's laptop. She will just have to go with the expense of buying compatible memory.
Thanks again, for saving me from an embarassing mistake.
