Intel Pentium G850 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 G850 Processor Load State

Here is a CPU-Z v1.58 screen shot of the Intel Pentium G850 to see what we are going to be overclocking.  The processor has a base clock of 100MHz with a multiplier of 29. 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 G850 also doesn't have Turbo Boost, so the only thing that we can do to really overclock the CPU is to increase the base clock or bus frequency as some people call it. Intel 'Sandy Bridge' processors don't like to have the bus increased too far though, so overclocking on this processor is going to be rather tough.

Intel Pentium G850 CPU Overclocked

With everything left to default in the BIOS and by just raising the back clock frequency we were able to reach 105 MHz base clock in a matter of seconds. This helped increase the overall frequency of the processor up to 3039 MHz, which is an increase of roughly 131 MHz.

Intel Pentium G850 CPU Overclocked Results

We wanted to see how this benchmark performed as the CPU was now running at 3039MHz and the memory clock speed was at 1957MHz. We ran x264 HD 4.0 and sure enough we saw a performance increase from this simple and obviously effective overclock. We saw a 4.5% performance boost on the first pass, which is great as our overclock is only 4.9% in itself. It's great to see a measurable performance difference from something this simple and the best part about overclocking is that it is an entirely free performance boost and it is fun to do!
