Cisco has a list of approved third-party memory vendors that you can use.
In speaking with a technician about upgrading some routers, he gave me
vendor part numbers and everything. I'm quite sure Kingston was on the list
as well.
One thing I did run into lately was early early early revisions of the 2500
series not taking Kingston memory due to some kind of requirement for an
intel chip ID.
