AM3 Socket Heatsink Mount

Hello. I upgraded my cpu to AMD Phenom II BE X4, but the heatsink that comes with it will not latch on to my motherboard(it will only allow screw on heatsinks). I have Dell 04GJJT motherboard. Can anyone send me a link to a heatsink mount, thank you.

Thats the problem... You have an OEM Dell motherboard. You can use ONLY Dell parts. Sucks, but i know from experience...

I would assume that RyTak is correct. Dell, HP, and other OEM's are known for such things.
