It was not an easy decision how to award the benchmark points in IsMyMemoryOK on Windows 12, 11, 10 and other versions, but here is the final solution:- Sequential reading and writing per MB per second is worth 1 point - The other 3 values ( 4K Random , 1K Random , and 64 x 10 MB Random ) each get 0.33 points per MB/second as these measurements are very similar. There are no additional bonus points for access time as it already influences the last 3 values. Giving points to access time would result in double scoring . At the end, the total score is simply made up of the reading + writing values and divided by four . Example for DDR3 RAM 1600 Dual-Channel:- Reading : 9450+(9060+4040+11180)×0.33 = 17783.6 / 2.0 = 8891.8 - Writing: 8400+(7430+3060+12520)×0.33= 16719.3 / 2.0 = 8359.65 - Total 17251.45 / 2.0 = 8625.7 points This represents an average transfer rate of 8625.7 MB/s , or about 8.6 GB/s . The theoretical maximum bandwidth of DDR3-1600 RAM is 12.8 GB/s per channel. In a dual-channel setup, this bandwidth is doubled, resulting in a theoretical maximum bandwidth of 25.6 GB/s. In practice, however, the absolute maximum values are rarely achieved, as measurements typically simulate the average application range. In real-world conditions, about 8.6 GB/s is a realistic bandwidth that corresponds to the average. These values reflect the performance achieved under normal operating conditions, as opposed to the theoretical maximum values that are only achievable under optimal circumstances and ideal hardware configuration.

Intel systems often score highly in single-core performance, while AMD systems are superior in multithreading, resulting in a balanced overall score that represents the average transfer rates well.
