What we did like:

Obviously we loved the capability of the RAM to work with 3/3/2/8 timings at 250MHz and even tighter timings at lower speeds. Up to today no other PC4000 rated 1GB module could work with tight timings at such a high speed. This aspect is something that enthusiasts and gamers will love, so now there are no compromises between high speed and large capacity.

What we did not like:

We believe that the set has only one negative point. It appears that no matter how easily the kit can work at 250MHz with such tight timings and low voltage, no matter how much one will loosen the timings and up the voltage they will not be able to overclock much higher. Our particular kit hit a wall at 260MHz. The older HZ series could not work with (nearly) so tight timings but could overclock higher with loose timings if it was needed.

Who we would recommend it to:

As the tight timings affect mainly 3D performance, we would recommend the HV series kit to serious gamers. Of course, anyone who requires a hefty amount of fast DDR RAM will find the G.Skill HV series kit a very noteworthy part for their system.

We believe that the G.Skill F1-4000BIU2-2GBHV kit is worthy of our Heavenly Hardware Gold Award. It is the currently fastest 2GB kit and it seems like it will stay this way until the passing of DDR.
