Utilize Threadripper 3990x at maximum output using Gaussian.
Hey there! Let's chat about your plans for the new machine. You're thinking of upgrading to a Threadripper 3990x and adding another workstation for your chemistry research. That sounds like a solid move to boost performance for those long hours in the lab.
Your boss wants it running nonstop, which is great for productivity but does mean higher power demands. Custom cooling and overclocking could help, but you're right to question whether it's worth the effort. Running stock or a light overclock might be more stable and easier to maintain.
I noticed you mentioned seeing other people avoid overclocking for critical tasks—maybe that's a good approach. It's all about balancing performance with reliability, especially when uptime is key. What do you think about sticking with a solid stock setup and monitoring closely?
Running an OC'd CPU under heavy stress isn't ideal for longevity. I suggest a dh-15 with solid overclocking potential, though the NH-U14S seems capable of light OC at moderate loads. You likely won't need a power supply that's overly powerful, but an 850/1000W unit would be beneficial. Regarding the motherboard, prices have risen significantly, so quality matters more than cost. Ensure the board isn't faulty and has good reviews. For extreme overclocking, consider a custom loop or high-end AIO options like 360mm or 480mm. A Noctua Dh-15 works well for mid-range overclocking, and the U14S should handle light OC under normal use. Threadrippers can be cooled well at stock temps, but they heat up quickly with higher power.
Many systems operate continuously, handling high-priority tasks or running on dedicated workstations without overclocking. While it's feasible to push components beyond their limits, doing so carries potential dangers. With thorough testing, a reasonable overclock seems achievable. In my view, a modest voltage increase shouldn't shorten the CPU's life—meaning it can still function efficiently without excessive power. Temperature is another concern; even small rises can lead to lasting damage over time, but maintaining below 85°C should prevent noticeable issues within two years. Regarding cooling, liquid systems introduce risks and demand regular tuning or replacement each year on gaming rigs. For continuous operations, more frequent upkeep might be necessary.
According to my understanding, the NH-D15 isn't available in a TR-version. During testing I observed that the NH-D14 threadripper performed better than the BeQuiet threadripper dark rock pro 4, even though the NH-D14 is a single tower and the BeQuiet is a dual-tower cooler. The improved contact with the IHS likely contributed to its performance. I don't believe the NH-D15 has been tested, but would it still surpass the 14-TR-version with a standard contact plate?
