Intel 45nm Yorkfield Runs On 975X Motherboard
 

We've gotten more than a few inquiries from readers, since we launched our Intel Core 2 Extreme QX9650 (aka Yorkfield) article, about whether or not the new 45nm quad-core chip from Intel will play nice in legacy motherboards. The party line from Intel is that while technically, Yorkfield quad-core processors are not supported by chipsets like the 975X and P965, some motherboard manufacturers may choose to validate and support the product.

We've recently been able to prove out that on at least one 975X board, the Asus P5W64WS Pro, using one of Intel's new 45nm Core 2 Extreme QX9650 processors. More than likely any 45nm quad-core Intel processor as well is a go.
