Lavalys Everest 5.3 Memory Performance

Website: Lavalys



Read performance is, as we'd expect, progressively better as we lower the latency and jump to a higher clock speed. Note that it actually drops for the lowest latency settings - this indicates that we are on the verge of stability and that some bandwidth is lost in errors rather than getting stuff sent quicker.



The write performance is clearly dominated by CPU northbridge frequency, rather than any memory timing or frequency as the write results are virtually entirely uniform. This is to be expected, since the CPU is writing to memory, and clearly there's no limitation even from the slowest 1,600MHz CL9 setting.



Copy performance is a little bit everywhere. It averages around the 20,000MB/s mark across all the tests, but there's no real trend line.



The overall latency is obviously affected by reducing the memory latency, with a clear reducing trend-line as we drop the timings or increase the frequency equating to a 13 per cent reduction across the 1,600MHz range alone and 17 per cent from 1,600MHz CL9 to 2,000MHz CL7. Varying CPU memory controller frequency doesn't have much affect, with a similar 11 per cent reduction from 1,800MHz CL9 to 2,133MHz CL8.
