Test Results: Samsung PC3700

To test overclocked stability, we used the very demanding Gun Metal 2 - Benchmark 2, which pushes systems with its DX9 routines. To be considered stable for test purposes, Gun Metal, our Quake3 benchmark, UT2003 Demo, Super PI, Halo, and Comanche 4 had to complete without incident. Any of these, and in particular, Super PI and Gun Metal, will crash a less-than stable memory configuration.

Performance at DDR400 is in-line with Samsung's spec of CAS 2.5 operation at DDR333. We were not able to achieve CAS 2.0 at DDR400 with the Samsung modules. While this is slower than what we have seen on recently tested modules at DDR400, the actual benchmark performance is closer than you might expect to the performance of other high-speed modules at DDR400. While other modules outperform Samsung at DDR400, the PC3700 performance was still very solid.

The most surprising finding was the tremendous headroom of the Samsung DDR466 modules. Rated at DDR466, we were able to achieve stable operation to DDR535. This is as good as we have found on many DIMMs rated at DDR500, and is excellent headroom for a DDR466 rated module.

Samsung specifies the JEDEC standard 2.6V +/- 0.1V for the memory voltage and test results confirmed this specification. Increasing memory voltage to 2.85V did not improve stability or allow a higher overclock.

    The Samsung module is such a disappointment. I am better off with OCZ 3700 Gold, as it costs about the same, but runs faster. Reply

    Albatron (and others) guarantee 1000MHz P4 (4x250) mainboards (on the box) so you'd expect DDR500 to be the new JEDEC.

    What is the speed of these CC5 chips(the samsung link doesnt give that info)? They dont seem to be much different to the earlier 5ns chips.

    I already have some crucial pc3200 that does ddr500 at 3-4-4 timings with 2.8v. Reply

    "The next bump in the DDR road would be DDR533, but with DDR2 set to launch in the very near future, it is not likely a DDR533 standard that will ever see the light of day."

    Hmmmm... well, that's what they said about DDR400 as well. We'll see soon enough, I'm sure.
