After installing the two memory modules, we checked from the BIOS utility and then with CPU-Z to see the SPD Timings. As you can see, 3-4-4-10 running at 250MHz (dual channel) is the SPD setting.

However, when setting the DDR configurations to AUTO, the BIOS will not let the memory run higher than 200MHz (3-3-3-8, dual channel).

For these tests, we used an AMD Athlon 64 3500+ CPU (Newcastle), running at 2200MHz.

In this review, we will be comparing the Apacer Real500 Ram Modules with the Corsair XMS TwinX 1024-3200XL. Below you can see the SPD Timings for the Corsair XMS memory modules, according to CPU-Z.

Here's a rundown of our testbed:
