Investigations into Socket 939 Athlon 64 Overclocking

Test Configuration

9000 words into the article, and we still haven't even given you benchmarks or tested settings. Hopefully, we've managed to convey something of the complexity involved in overclocking. If you already knew all of the preceding material, think of it as a quick refresher course. If you're new to overclocking and skimmed most of that, your success in overclocking is going to be limited. Patience is a major component for any overclocking endeavor. Skimming a guide, finding some tested numbers, and plugging them into your BIOS may work fine, but more likely, you'll have periodic instability and you'll be stuck as to what needs to be changed in order to fix the problem. Now, we're finally ready to give you our test setup and the settings that we used for the various overclocks.

Our system configuration is definitely targeting value rather than the high end. The OCZ RAM is decent, but the remaining parts are mostly mid-range. We've listed the current prices in the above table, and we're looking at about $900 without the monitor, keyboard, mouse, speakers, and power supply - assuming that you use the included PSU in the Antec case. Dropping to value RAM can cut another $70 from the price. While a slightly nicer PSU isn't a bad idea, the OCZ 600W is overkill for non-SLI setups, for sure - which is why we list it as an alternative. If you're looking at running an Athlon 64 X2 with 2x1024MB of RAM and dual 7800GTX cards, we've seen an overclocked setup actually break the 400W mark, so 600W might not be a bad idea in that case.

The graphics card is going to be something of a limitation, as the X800 Pro is certainly not going to compete with a high-end card like a 7800GTX. For the cost, though, it's really not a bad choice. The X800 GT and GTO cards also look good, priced at under $200. Since we're looking at a value-oriented overclocking setup, running a high-end graphics card that eats up more than half the total cost of the system is a bit extreme. However, we'll try to get some benchmarks in a future article looking at exactly that sort of setup. For gaming, at least, the GPU is going to be the critical factor in reaching high frame rates

Because of the GPU limitation, we're going to be testing at 640x480, 800x600, and 1024x768. We'll also test many of the titles with 4xAA enabled, which should serve as a reality check. Even with a super fast CPU, many games are going to be completely GPU limited with the X800 Pro when we run 4xAA, especially at resolutions 1024x768 and above. Frankly, we wouldn't bother enabling 4xAA unless you can at least reach 1024x768 anyway.
