The once-popular Intel Xeon X5650 just can't cut it in 2021. Is an overclock on the old LGA 1366 platform worth the effort, or is it time for a new build? We investigate its real-world effectiveness.

We test the overclocking potential of the classic Intel Core 2 Duo E6550 to see if pushing this aging CPU actually makes practical sense today.

Intel Xeon E5440 express test: compatibility issues, overpriced, better alternatives exist. Includes a bonus Xeon W3520 test.

Retro overclocking the Intel Pentium D 930: we overclock the processor to 4350 MHz and test its performance in DiRT 3 and synthetic benchmarks.

A retro overclocking deep dive: pushing two AMD Athlon II X2 260 (C3) chips from Taiwan and Malaysia on AM2+. The Malaysian chip showed better potential, hitting 3983 MHz.
