Verdict: A great kit, providing you overclock it

With so many different speed grades of DDR2 now available, it can be difficult to choose the right RAM for your PC. It also doesn't help that companies such as G.Skill produce a number of different kits with the same rated speed.

G.Skill isn't one for creating short and snappy titles for its kits, but at least the model numbers make it easy to see what you're getting. The F2-6400PHU2-2GBHZ is rated as PC2-6400, so it's guaranteed to run at up to 800MHz. Its latency timings are a fairly decent 4 - 4 - 4 - 12, and it needs 2.1V to operate. At these settings, the F2-6400PHU2-2GBHZ isn't a great performer, slipping behind the lower-latency Mushkin XP2-6400 in most of the tests. This is quite disappointing, considering the higher price of the G.Skill kit.

However, the F2-6400PHU2-2GBHZ is much more overclockable than any other PC2-6400 kit in this Labs test, running stably at 1GHz at its default latency timings at 2.3V. If you're building a Core 2 system (which doesn't benefit from low latency timings) then the F2-6400PHU2-2GBHZ can be overclocked to 1.12GHz at 6 - 6 - 6 - 18, which is a great result for a PC2-6400 kit.

The G.Skill isn't the cheapest PC2-6400 memory available, but its good overclocking potential makes it one of the best sub-£200 2GB DDR2 kits you can buy.
