Here’s a chart to show you which nForce chipset supports the new 45nm cores (Deneb, Heka, Regor). Basically, MCP68 based boards will not support the new processors while MCP61, MCP72 and MCP78 will be able to support. You can head over here to check the list of motherboard models that support the new CPUs.
