River, if any of them would take a uFCPGA [CPUz identifies it worng as socket BGA2] (never konw, they are small form factor. It a laptop socket.)
I may be able to get you a large super duper fast upgrade to a whole 1000MHz.

Thanks for the thought FuzzyChicken. All except one are slots (of different kinds) and the other, a Dell desktop, certainly won't be a laptop socket.
