I tried to upgrade my ram and the new sticks wont work. Even using just one, I tried each of the slots and it still does nto work.

My system specs are:
Abit NF7 Series 2.0 Motherboard
AMD Athlon 2500 Barton
I have 2 512 MB PC 3200 Kingston Value Ram Sticks that run fine in dual channel mode.

I wanted to upgrade to 2 1 GB sticks of Samsung RAM and they did not work in the system. I get a long beep that repeats. Do you have advice for me?

That board supports PC 2700 and pc 3200. for one gig sticks it looks like you need pc2700. there is no dual channel support.

I see no support for dual channel. the timing is probably wrong for your board.

Dual channel PC3200 is timed at CAS 2.5 or 2.0 your board only supports CAS 2.5 in single channel mode.

What works in your board?

from here there are two possibilities:

your board does not support what you are trying to install

bad new ram

You bought dual channel. your system bord does not support CAS 3.0 with densities over 512 mb when dual channel is run in single channel mode, it times to the CAS 3.0. you must use PC2700 in this board, single channel only.
