OCZ 3700EB: Making Hay with Athlon 64

Intel Test Results: OCZ 3700EB

To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and Comanche 4 had to complete without incident. Any of these, and in particular Super PI, will crash a less-than stable memory configuration.

At DDR466, OCZ 3700EB was able to run our complete memory test suite at SPD timings. The DIMMs were stable at the standard 2.5V to 2.6V at the rated timings at DDR466, which is even lower voltage than specified. As we saw in our earlier EB review, the memory can handle voltage and rewards higher voltage with even better timings at the high end. We achieved the best performance on the Intel test bed with the lowest Cycle Time (tRAS) that we could run. Therefore, tRas on Intel chipsets should be set at 5 or 6 for the best performance, rather than the 8 set in SPD.
