I have it in a DFI Lanparty Ultra Revision B NF2 and a AMD xp Mobile 2600+

fsb = 133 multi = 15 and i have it at a 1:1 ratio


two problems.....

The system will consistantly just restart, no blue screen no warning, and the ram only shows up as 256mb

is there something i am doing wrong? is unbuffered special ram? what should i do here?

i'm assuming you tested in all slots?

Is it a single sided stick? It's possible that the board can't read the density of the IC's. Definitely try it on another system though, to make sure the results are repeatable.

yep, tried it in three seperate systems....

Ask for a refund and buy some quality RAM.
