i think they're classifying them mid-range based on

1. price range
2. binning process

We asked in the beginning if the G.Skill mid-priced DDR2-800 4-4-4-12 delivered value. Since you can reach all the same timings up to DDR2-800 if you have the voltage to supply, then it certainly can perform just as well as top-line to DDR2-800. The F2-6400PHU2-2GBHZ can also reach to DDR2-1067, with the performance improvements that can bring, although it does require slower timings than the best DDR2 tested at AnandTech. Finally, for those budget buyers who are using motherboards that can not supply voltages above 2.0V to 2.1V, the G.Skill will run at DDR2-800 4-4-4-12 at a very modest 1.9V. Overall, the G.Skill DDR2-800 gives excellent value, matching or coming close to the best we have tested to DDR2-800 with excellent overclocking beyond. There are certainly better performing DDR2 kits available, including some from G.Skill themselves, but for the money you will pay you definitely receive excellent value with this G.Skill 2GB DDR2-800 kit.

1 set does 540mhz 4-4-4-12 at 2.4v. 563mhz 4-4-4-8 at 2.54v vdimm

Better than my OCZs which Anandtech has at 4th on their performance list.

Damn that pisses me off eva
