The Cellshock PC2-8500 memory can almost be described as perfect. It comes rated at 2.3V, which may turn some people off, but our review kit managed to do the rated speed at 1.85V without much trouble. Cellshock impresses at every CL rating with great performance. For those who cannot use 1066 MHz, the 800 MHz CL3 rating may be of interest, but sadly this is not something that is apparent for the potential buyer. If Cellshock were to also mention that the memory can handle CL3 at 800 or CL4 at 1000 MHz, it may be more attractive to a larger user base. The great attributes of the memory do justify a price premium, but you may be hard pressed to spend 40€ more when you know that other brands doe the same speed for much less. The Cellshock memory gives you pretty much the complete spectrum of speed and CL ratings available, which makes the memory one of the most versatile kits out there.
