SDRAM Configuration -  By SPD

System/SDRAM Frequency Ratio – 1/1

With these settings the RAM was running at 100Mhz (Same as bus speed) at CAS2.

Using my previous 128MB RAM modules with the same BIOS settings I got the following results.

As you can see, the Mushkin RAM offers a small improvement in memory bandwidth over my older PC-100 RAM with the same memory timings. This is mostly likely due to the superior design of the Mushkin RAM (Seeing as all other things are equal settings wise).

Next up is the results with the following BIOS settings using the Mushkin RAM once more;

SDRAM Configuration -  By SPD

System/SDRAM Frequency Ratio – 3/4

In this case the RAM was running at 133Mhz at CAS2.

As you can see running the RAM at 133Mhz does increase memory bandwidth, although not too significantly. It seems that a greater boost to memory bandwidth had resulted from upping the memory bus speed from 66Mhz to 100Mhz. The shot below illustrates what I mean. To test memory bandwidth at 66Mhz I set System/SDRAM Frequency Ratio – 4/3, with the FSB at 100Mhz.

As you can see memory bandwidth is significantly lower at a 66Mhz memory bus speed.
