My friend just gave me some ram.

2x1gb of ddr2,Kingston, 667

I thought it would be as easy as putting them into the empty slots. SO I did, next to my corsair 2x1gb ones and turned the pc on. All I got was a continuous beep. So I pulled out all the ram and ut one in at a time, tried some combos, and nothing but a continuous beep sound when I use one/both of the new ones.

The kingstons are sitting on my desk atm. Not sure why it didn't work.

Thinking, the ram is bust, or I have to change voltage settings?

note: There was some yogurt on the ram when he gave it to me but I removed it carefully and it looks fine. I thought ram was better then that.
