As for the information we managed to read from the SPD of these memory modules, there is nothing that would indicate their higher overclockability.
The SPD of these memory modules contains timing settings for all DDR2 frequencies approved by JEDEC. If we believe the screenshot above, Kingston HyperX KHX7200D2K2/1G can work at 400MHz with 3-3-3- timings, at 500MHz with 4-4-4 timings, and at 667MHz with 5-5-5 timings. In fact, this is none other but the Infineon memory chips characteristics, these memory modules are built with. However, the memory modules SPD should first of all minimize the number of compatibility issues when the memory module is first installed into the motherboard. Therefore, SPD should contain the timings settings, with which memory modules are guaranteed to work at the DDR2 nominal voltage of 1.8V. This task is definitely fulfilled by the SPD of Kingston HyperX KHX7200D2K2/1G memory DIMMs, because it contains exactly the official chips specification data.
Overall, I would like to specifically point out that Kingston engineers did a very good job on filling out the SPD data. Besides the “correct” timing settings, you can also find the time these memory modules were manufactured and their unique part number.
Testbed and Methods
To test the overclocking potential of Kingston memory kit, we assembled the following platform:
- Intel Pentium 4 520J CPU (2.8GHz, 1 MB L2, Prescott D0);
- ASUS P5WD2 Premium motherboard (LGA775, Intel 955X);
- Kingston HyperX KHX7200D2K2/1G memory;
- PowerColor RADEON X800 XT (PCI-E x16) graphics card;
- Maxtor MaXLine III 250GB HDD (SATA150);
- Microsoft Windows XP Professional SP2 OS.
The motherboard BIOS settings were as follows:
- Performance Mode: Auto;
- HyperPath3: Enabled.
This is exactly the same system as the one we used for our tests of other overclocker’s memory modules. Therefore, we will be able to compare the results we will obtain today with the performance of the competitor’s solutions, to get a clearer picture.
