peter, it appears that it will not work, since your chipset does not support the processor.

Dell optiplex gx280 doesn't support dual-core.


@gigabit87898 do not simply downvote this. You need to clarify whatthe poster tried to say. This could have been a question as well. Do not use downvotes trying to prove a point or because you believe to know better. Only blatantly wrong or willfully disruptive answers should be downvoted. Always consider what would happen if the show is on the other foot.....
