The most noticeable difference between the DDR3-supporting P45D3 Platinum and its DDR2 counterpart is its DRAM voltage range, though there are small differences in CPU core voltage as well.
The top of MSI’s P45D3 Platinum “Cell Menu” looks identical to the P45 Platinum.
Since we tested the P45D3 Platinum with DDR3 memory, we used a lower voltage.
The Advanced DRAM sub-menu has been altered to match the different timing controls of DDR3 memory. We set both DDR2 and DDR3 motherboards to 1066 MHz data rate and CAS 5-5-5-15 to keep the competition fair.
The Memory-Z sub-menu detects DDR3 timings in this case, and clicks through to another menu showing Intel X.M.P. timings.
We wondered if installing EPP 2 modules would have shown a modified menu, since the DDR2 version of this design provided EPP values.
The P45D3 Platinum has four user profile registers, rather than two, so twice as many BIOS configurations can be stored compared to the P45 Platinum.
