OCZ DDR2-800: The Third-Fastest Test Candidate

THG is well acquainted with OCZ. Last year, we ran a number of their products through our test labs. This time, they sent us a DDR2-800 module that achieved results comparable to those we observed with Kingston's RAM device- they topped out at 984 (492 MHz) - a thoroughly respectable value - and thus demonstrated high overclocking potential. But when it came to the timing test, OCZ didn't exactly shine: Even at high input voltages of 2.2 v their modules couldn't operate at CL3.0 timings. We also noticed that the SPD values stored on the chip included only latency timings for DDR-800 (400 MHz) clock rates, rather than the more typical two- or three-tiered settings most other vendors provide.
