After installing the two memory modules, we checked with the BIOS utility and with CPU-Z to see the SPD Timings. The memory uses two SPD timings. When the frequency clock is set to 400MHz, the memory will go with 2.5-3-3-7 timings, but if you choose to reduce the frequency clock to 266MHz (cannot see why someone want to) you will have 2-2-2-5 timings.
Of course, in this review, we will be testing the Kingmax DDR-400 modules operating at 400MHz (200MHz - 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 Kingmax DDR-400 with the Corsair XMS TwinX 1024-3200XL and Apacer Real500 Ram Modules. Below you can see the SPD Timing for these memory modules, according to CPU-Z.
- Corsair XMS TwinX 1024-3200XL
- Apacer Real500
