NO! You can't put a Core 2 Quad on the Inspiron 530 mobo's that didn't come with a quad standard. Dell cheaped out and didn't put enough voltage regulators to handle a C2Q on the boards that come with a Dual or Single core system. I have a Studio 540 (same thing basically), but I got a Core 2 Quad in mine. Then moved it to an new case and PSU.
