DDR3 Memory Performance Analysis on Intel X79

Final Thoughts and Conclusions

We were easily able to get single, dual, triple and quad channel memory working on the Intel DX79SI motherboard. We found that the memory bandwidth increased in a relatively linear fashion and all of the benchmarks came out like we expected. If you are looking to save a buck, you shouldn’t have an issue running less than a quad channel configuration. To get the most from this platform then you’ll want to stick with four memory modules. What speed you ask?

When it comes to memory clock speeds with quad channel memory kits we found that memory bandwidth also increases linearly until we were forced to adjust the memory timings. Being able to run 2133MHz on this board with just some minor changes in the BIOS was pretty impressive. We were hoping to get 2400MHz memory running on this board, but we just could get into Windows 7 Ultimate 64-bit with that multiplier. We tried various timings and voltages, but the platform just wasn’t cooperating with us. The memory will hit 2400MHz with this memory kit on other motherboards, so it looks like the Intel DX79SI motherboard is the culprit.
