After installing the Kingmax 2X512MB 667MHz memory modules in our test system, in dual channel mode, we ran CPU-Z in order to see how they were identified by WinXP (SP2).

The first tests were done at 533Mhz with 3-4-4-11 timings, a setting which is automatically detected from the SPD. Below you can see further details for the memory and the CPU:

The next step was to set the memory to run at 667MHz. For this we had to change the timings to 4-5-5-13 and increase the FSB from 200 up to 250. The configuration is given below.

Finally, we tried to find the highest operating frequency for the memory. With the contribution of Memtest86+, we managed to set up the memory modules to run up to 693MHz. The FSB had to be set to 260. The CPU at this point was running at 3.90GHz while the memory voltage was set to 2.2V. At higher speeds, even at 698 for example with lower timings of 5-5-5-15, Memtest86+ reported errors. Despite this, the confirmed 693MHz is quite good.

In Memetest86+, the reported bandwidth for the highest overclocking speed was 3469MB/s and 3752MB/s for the Kingmax and the OCZ memories respectively.

In the following pages, we will be comparing the performance of the Kingmax memory modules against that of the OCZ PC5300. The nice thing here is that both memories are very similar, something which makes for a good comparison.
