I just want to extract the maximum performance from the machine to increase profitability. More data I can process in this 2 years means make more money.

So far through benchmarks, we found about a 2-3% in certain phase of processing especially where RAM usage is very high. In some others not so much as the software is GPU dependent in some phases. Of course the largest improvement was in improving the cooling of the system by tweaking the airflow though the casing and AIO and also improving the contact between the heat block and CPU. The CPU stayed at higher clock speeds for longer resulting in almost 5% everywhere.

The software somehow responds better to higher clock speeds than more parallel cores. Before this when we were using precisions, we had a 8 core 3.8ghz Xeon running on ddr3 and a 22 core 2.x GHz running on ddr4. We found the 8 core still churning out data faster than the 22 core. That's why my quest to have stable and higher clock speeds as opposed to more cores.
