Oh, you might be right. Not sure what you mean by TLC. But indeed the charts lack an explanation, so I've looked instead into this table: https://zsmith.co/bw-

Oh, you might be right. Not sure what you mean by TLC. But indeed the charts lack an explanation, so I've looked instead into this table: https://zsmith.co/bw-table.php https://zsmith.co/bw-table.php First row for Intel Core i7-930, DDR3 2000 MT/s he should be getting at most 16GB/s for reading from DRAM modules (not cache), but he's actually getting 18.4 GB/s, big 15% more. Maybe more cores were used, then the theoretical limit of that processor is 25.6GB/s, and the result is not that great. But then for i5-520M, 1066MT/s he should be getting 8.5GB/s per core, but he's getting less, only 7.1GB/s. Maybe contact the author (his email is in README.txt) and ask for clarifications on these discrepancies and help on your problem. I think there is a problem somewhere with your system/measurements. With 6000 MT/s, there's no way getting 25GB/s is fine - that's what DDR4 3200MT/s should able to do. You should be getting close below 48 GB/s on one core, and 89.6GB/s multicore. And writes should be slower than reads.
