I purchased used out of warranty service HP Z440.
As I need to improve its performance I need to overclock CPU. How can I access to those options in BIOS? I have bios M60.
i know that HP do not support Overclocking because I can damage my product but as said it’s out of warranty so any damage is my risk.

your first post--- is at 07-20-2019 09:56 AM
your second post is at 07-20-2019 10:42 AM (less than 60 min has passed) and is all caps, which is considered shouting
please be patient, and wait a reasonable time before posting a followup and use lower case
most OEM systems (HP included) have no way to overclock a CPU therefor if your into overclocking find another system that has support for it
most workstations are made to run 24/7 without errors and overclocking a workstation runs counter to that
if you require more performance than the current z440 system's CPU has replace the CPU with a faster or higher core count CPU , add more ram or replace the z440 with another system

There are various ways common to any system improvement, and the applications/use is important to focus the components for improvement. Improving the single thread performance- the speed of the fastest core(s) is a primary one,, that helps everything, but in heavy dataset, development, compute, rendering, and simulation, more cores may also be important.
The z440 has a particular potential in that the Xeon E5-1650 v3, 1660 v3, and 1680 v3 have unlocked multipliers and may possibly be overclocked using the Intel Extreme Tuning Utility or "XTU". This is a free software and uses only two settings: multipler and added voltage for stabilization- to overclock unlocked Intel CPU's. I use it in an HP z620 to run an E5-1680 v2 on all eight cores @ 4.3GHz and in a z420 / E5-1650 v2 6-core @ 4.3GHz. In both cases- literally- liquid cooling is used.If XTU can not be used in a z440, the Xeon E5-1650 v4 is locked but has one of the highest stock E5 single thread ratings.
The z440 must have the proper LGA2011-3 motherboard to accommodate a v4. The motherboard series is important to have in hand before doing anything with the processor. Those with 420's, z620.s, and z820's know this problem as E5-v2- which are faster and may have more cores than the first series, are not compatible with the first version motherboards. With zx20 series, the first series is 2011 boot block date, and for 2nd series, a 2013 date.
XTU is mentioned speculatively because I'm not seeing examples in HP workstations of overclocked E5-16X0 v3's. There are E5-1650 v3's running at 4.7GHz, but on ASUS, Gigabyte, and MSI motherboards. If this is interesting, consider researching XTU on E5-16X0 v3's. It can not be used on the E5-26X0 processors.
Otherwise, a higher performance GPU is the best important improvement, and I would recommend considering the new NVIDIA RTX 2070 Super for about $500 which has 3D performance averaging above the GTX 1080 Ti. More RAM, and faster drives- M.2 make a difference too, but in my view, the single thread score is the best place to start.
For more specific recommendations, list the components in the z440, the most important uses, and which aspect of the performance is the problem. Considering running the Passmark Performance Test benchmark (there's a 30-day free trial) and posting the results as that can reveal the weakest links in the system.

It was worth trying XTU on your system. As mentioned in the earlier reply, certain Xeon E5-16XX v3 processors do have unlocked multipliers and on Passmark baselines there are examples of E5-1650 v3's running at up to 4.7GHz, but only on ASUS, MSI, Gigabyte, and etc motherboards.
As overclocking greatly increases the risk of system instability, by inducing thermal limits and chip degradation by removing power limits, workstation manufacturers discourage it.
Today, a larger proportion of workstations, especially for use in applications that demand very high single -thread performance such as 3D modeling using unlocked gaming CPUS. There are quite a number benchmarks of systems with an i9-9900K at 5.0, 5.1, and 5.2GHz but also using Quadro GPU's, and these are workstations with a gaming processor but running Solidworks, Catia, Siemens NX, and etc.- and not Firestrike 5.
