The recently acquired HP Z4 G5 Xeon workstation CPU just don’t get past 4Ghz threshold?
According to Intel turbo boost Max spec, W3-2435 Xeon theoretically can go 4.5Ghz single core without thermal throttling. My CPU idles at 43 deg C, and max well below 65 deg Celcius. The process never pass 4 Ghz.
Single core speed is important to me since I use Solidworks which is a single-cored application for modeling unless I run simulation for CFD which will utilizes all 8 cores.
Is there something I need to tweak in BIOS?

I had the w3-2423 and it almost never reached its max boost frequency which was bad because the chip is horrifically slow otherwise and the all core turbo is really low, disabling power limits helped but only a little
can only suggest seeing if there are any BIOS updates, I dont have a HP but for me, each BIOS update has improved the general performance by a noticeable amount
I doubt the bios of an hp prebuilt has any useful option but on normal motherboards there’s a tab to set cpu max boost depending on amount of cores active. Check if it’s limited to 4ghz, and try to play around with power limiting/saving options if there are any.
If it doesn’t work you could try using throttlestop or intel xtu.
