Testing and Results
Before I begin any benchmarking or overclocking, I thoroughly stress the CPU and memory by running Prime95 on all available cores for 12 hours. If no errors are found, I move on to a gaming stress test. To do this, I use Prime95 again to stress the processor, while running an instance of FurMark's stability test on top of this. If the computer survives this test for 2 hours without lockup or corruption, I consider it to be stable and ready for overclocking. After achieving what I feel is stable overclock, I run to these tests again for certainty. The goal of this stress testing is to ensure the clock speeds and settings are stable before performing any benchmarks. I adopted this method from another writer here at Benchmark Reviews and it seems to do a great job of flushing out what only seem to be stable overclocks.
Once the hardware is prepared, we begin our testing. Each benchmark test program begins after a system restart, and the very first result for every test will be ignored since it often only caches the test. This process proves extremely important in the many gaming benchmarks, as the first run serves to cache maps allowing subsequent tests to perform much better than the first. Each test is completed five times, with the average results displayed in our article.
For our Athlon-II X2-255 review, the following test systems and comparison processors will be used. As was mentioned before, the Athlon-II X2-255 will be compared to older systems to judge its value as an upgrade option. We fully anticipate the the Athlon-II X2-255 to be the fastest processor in our test-bed for this review. If it is not, we would be disappointed in the performance it provides for its price. At $67, the Pentium Dual Core E5300 2.6GHz is very close in price to the Athlon-II X2-255, at $75 and 3.1GHz. We expect to see a better than $8 increase in performance between the two processors. The Core 2 Duo E6300 is an old Conroe processor running at 1.8GHz. We hope to see that the Athlon-II X2-255 provides a large performance increase, and thus an inexpensive upgrade opportunity, over the Core 2 Duo E6300.
