Hi,

I want to upgrade the CPU of my Optiplex sx280. The motherboard is a 0U2313. The current CPU is an Intel Pentium 4 2.8 GHz  520J (SL7PR). I have tried to replace it by a Pentium 4 3.6GHz 560 (SL739), but it's not compatible with the motherboard. Which processors are compatible with the )U2313 motherboard?

Thanks!
