The F2-4200PHU2-1GBNT are G.SKILL's latest budget DDR2 memory kit. Even though they lack heatspreaders they offer excellent overclocking. Our sample would go from the advertised DDR2-4200 up to a blazing DDR2-5800. What makes this kit even more attractive is that you can tighten the timings to 3-3-2-4. All this comes at a very competitive price of only $75 for a 2x512 MB dual channel kit.
