If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

AMD's 2.6GHz quad core 45nm Athlon II X4 620 processor is based on an architecture with a long and proud overclocking heritage, so you can bet PCSTATS is anticipating a fun round of overclocking from it.

Before the overclocking tests got underway, a set of Patriot DDR3-1600 memory was locked into the Gigabyte GA-MA790FXT-UD5P motherboard and set to run at DDR3-800 MHz mode. This way the memory won't hold the Socket AM3 CPU back from reaching its true potential. Keeping the CPU clock multiplier set to 13x (its default), the motherboard bus speed was increased slowly from 200MHz on up. Default clock speed on this chip is a respectable 2.6GHz... but PCSTATS is aiming for at least a 1GHz overclock above that.

Overclocking in 25 MHz increments, the Athlon II X4 620 CPU was rapidly pushed to 225MHz... 250... 275MHz bus speed without any signs of system instability, or the need to tweak any voltage settings in the Gigabyte BIOS. That's an overclock from 2.6GHz to 3.575GHz already!

Then, just as quickly, things went down hill. A bus speed of 300MHz was too much for the little Athlon II X4, and 285MHz Bus was a no-go as well.

Not to be discouraged, PCSTATS adjusted the bus speed to 280MHz and sure enough, Windows Vista finally loaded up without crashing.

Ultimately, the AMD Athlon II X4 620 processor overclocked from 2.6GHz to an impressive 3.64GHz on nothing more than standard air cooling, and without tweaking any voltage settings either. Nice! In the end, PCSTATS was able to squeeze a 1040MHz overclock out of this 95W TDP, 45nm chip. Not bad for a processor that costs just $99 bucks?

Prelude to Benchmarks

Over the following pages the AMD 2.6GHz Athlon II X4 620 processor will be put though PCSTATS standard set of gaming, productivity, and multi-threaded processor benchmarks. There are a wide variety of gaming and synthetic benchmarks here to illustrate what kind of performance boost users can expect from the latest quad-core socket AM3 AMD processor. Please take a moment to look over PCSTATS test system configurations before moving on to the individual benchmark results on the next several pages.

For this review PCSTATS is running the benchmark suite in both Microsoft Windows Vista and Microsoft Windows 7 operating systems. Hopefully this will help you make an informed decision in the coming months as Windows 7 adoption firms up. For the most part, benchmark results are not significantly different between the two operating systems, although certain tests do see advantages under Win 7.
