sdram question for hp

[MidNiteMysT]

im not new to computers and memory and ive replaced memory a few times. but im replacing memory on a friends computer and the website 4allmemory.com is saying
"Your Hewlett-Packard Pavilion 510n only supports modules made with a specific type of chip. Should you find what seems to be the exact same memory elsewhere for a lower price, it is very possible that the cheaper memory will not work in your computer."
which sounds like a load of crap to me. but i cant be sure since ive never dealt with hp.

they want to charge $55 for only 256 meg stick

new egg has pqi power ram sticks, but heres the question
new egg list

the first three pqi memory sticks look exactly the same, except for the last 3 digits at the end. can someone explain what those mean? then maybe i can see why there is a difference in price.

anyone?

Quick look shows nothing special about the memory

PC133 should work fine

I would download the manual and see if there is anything in there

if not just order it and try

yea, i didnt think there was anything special about the memory either.

although, why is one pqi more expensive than the other?

1
2
3

i cant seem to find the difference between the threee except that number 2 has p28 tagged at the end of the model number and number 3 has p68

can someone explain that to me?

Honestly I don't see one, though there may be a difference in chip density or something.
