Samsung PC3700

While the JEDEC DDR standard defines both TSOP2 and BGA (Ball Grid Array) standards, most memory manufacturers produce DIMMs with TSOP2 chips.

Samsung DDR466 is TSOP2 and uses the pins on each side of the memory chip for attachment to the PCB. The only high-speed BGA DIMMs that we have tested have been in our recent review Kingmax Hardcore Memory: Tiny BGA Reaches For Top Speed. Samsung supplied 4 single-sided DIMMs instead of the 2 double-sided DIMMs that we are accustomed to reviewing. However, as demonstrated in Searching for the Memory Holy Grail - Part 2, 4 single-sided DIMMs should perform at the same level as 2 double-sided DIMMs on the Intel 875 chipset used in the memory test bed.

For those memory enthusiasts who want to know every detail, you can find the Samsung Part Number in the chip close-up and locate all the specs for 256Mb K4H560838E C5 chips at Samsung.

Samsung DDR466 Specifications

 Samsung DDR466 Memory Specifications
Number of DIMMs & Banks 4 DS
Total Memory
256 Mb
1 GB
Rated Timings 3-4-4-8
Rated Voltage 2.6V +/- 0.1V

We confirmed the SPD timings to be set at 3-4-4-8. Samsung rates the C5 DDR466 chips at the same 3-4-4 timings specified for their C4 DDR400 chips. The timings and voltage specifications for DDR466 are the same as those published by JEDEC for DDR400.

The Samsung modules are rated at 2.6V +/- 0.1V, and this appears to be a very honest rating in our tests. Our highest memory overclock was achieved with 2.75V, and increasing the voltage to 2.85V did not improve stability in any way in the configuration that we were testing.

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

    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.

    "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.
