OCZ PC-4200EL Memory - Page 5

- ASUS P4C800E-Deluxe general testing procedure

After our disappointing results with the MSI Neo2-FISR we contacted OCZ, who suggested that we should use a motherboard capable of reaching high FSB speeds, like the ASUS P4C800E-Deluxe. Actually most PC4200/4400 work perfectly only with ASUS and several other motherboards, so it is suggested to search before buying memory that will not perform as you would expect…

Again each DDR memory module was placed in the 1 and 3 bank respectively. The following BIOS settings were used for all tests:

- Performance Mode (PAT): Standard/Turbo
- DRAM Frequency: 400Mhz
- Spread Spectrum: Disabled
- AGPI/PCI: 66.66/33.33
- VCore: 1.550V
- AGP: 1.60V
- DDR Voltage: 2.85V
- Burst Length: 4
- VIA Raid: Disabled

This time we decided to take a different approach to our testing and tested only four memory/timings as the following table shows:

Summarizing, we tested the following FSB/Divider/Timings/DDR Voltage:

As you can see the memory has no problem working at 2-3-3-6 at 201FSB with PAT enabled (Turbo). Actually, we enabled PAT for all the above testing FSB since it gave much better overall results. The maximum FSB we reached while maintaining a 100% stable system was 272 with normal timings, while relaxing timings (3-4-4-7), we reached the incredible 279 FSB. At that speed, the CPU reached 3.35 GHz!

Note that the system was fairly stable at 282 FSB but Prime95 Small FFTs reported errors, while the Blend test didn’t. Maybe with better cooling users can achieve even higher FSB. Another problem is that the ASUS P4C800E-Deluxe allows only up to 2.85V for DIMMs. There are several mods that can fix this problem, so there is certainly room for higher speeds for experienced overclockers.
