In our test, we run the 3.0 Ghz (P4 800MHZ) processor at 200Mhz FSB and with 2x256M Corsair DDR333 module at DDR400, CAS 2, 5-2-2 on the Canterwood boards. For stability, we set the voltage to 2.7v for the DDR. On the ABIT BH7 (i845PE), we ran it using a single stick of 512M Corsair XMS3500C2 at CAS 2, 5-2-2. PAT is enabled by default on all the Canterwood boards.

On the EPoX 8RDA3+, I ran the AMD Barton 400 (3000+) with 2x256M Corsair at CAS 2, 6-2-2. Even at 6-2-2, we find it a bit unstable and have to pump up the voltage levels to 2.9v for DIMM. Do take note that the nforce2 SPP is not officially supporting the new processor and in our test, we encounter hangs. The following results are gathered and should be regarded as a gauge of the Barton 3000+ (400) performance against the P4 3.0G (800) Performance.

From the chart, it is not difficult to see that the memory performance seems to have peaked at 3080 for Int and 3042 for ALU compared to the Canterwood which offers almost 55% more. Will this translate to better results by 50% or is there too much bandwidth remains untapped? Lets see.
