Intel Pentium G620 Overclocking

Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get. The Intel retail boxed CPU cooler was used for overclocking, so we'd expect this overclock to be easily reached by anyone!

Intel Pentium G620 Processor Load State

Here is a CPU-Z v1.58 screen shot of the Intel Pentium G620 to see what we are going to be overclocking.  The processor has a base clock of 100MHz with a multiplier of 26. This is not a 'K' series processor, which means it has a locked multiplier, so you can lower the multiplier in the BIOS, but you can not increase it. The Pentium G620 also doesn't have Turbo Boost, so the only thing that we can do to really overclock the CPU is to increase the bus frequency. Intel 'Sandy Bridge' processors don't like to have the bus increased much, so overclocking on this processor is going to be rather tough.

Intel Pentium G620 CPU Overclocked

With everything left to default in the BIOS and by just raising the back clock frequency we were able to reach 106 MHz base clock in a matter of seconds. This helped increase the overall frequency of the processor up to 2751 MHz, which is an increase of roughly 150 MHz and for a budget processor we can't really complain about a free performance boost. If you want to get more performance from one of these processors you are better off spending the extra $15 and getting the $88.52 Intel Pentium G840 as we were unable to match the 2.8GHz clock speed on that processor by overclocking.
