For these tests, we chose to use an AMD 3800+ CPU so that we could have results that we can compare with previous reviews. Our nForce4 based motherboard was an ASUS A8N-SLI Premium, operating in Single VGA mode. We also used the ASUS A8N-SLI Deluxe motherboard, just to see that there was no difference in the results. Setting the BIOS to auto configure the modules, we got the default frequency and timings for the OCZ memory on this motherboard which was 400MHz at 3-3-3-10.
However, CPU-Z states that the SPD timings for the memory is 500MHz / 3-3-3-10. We ran all the tests with the auto configuration setting on, running at 400MHz, and then we re-ran the tests at 500MHz by setting the values manually from the BIOS. In all the comparison charts in this review, you will see test results for both 400MHz and 500MHz operating frequencies.
The CPU we used was an AMD Athlon64 3800+, running at ~2400MHz.
In this review, we will be comparing the OCZ PC4000 XTC Platinum Edition modules with some memory modules we tested several weeks ago, the Corsair CMX1024-4000PT dual-rank modules (2GB), and the Mushkin XP4000 Redline modules. Below you can see the SPD Timings for these modules, according to CPU-Z.
