I have HP Z620 with latest bios which has a E5-1680v2 with a Z640 heatsink.
I've tried for last 2 days to overclock it using XTU to something like 4Ghz but it seem like based on the post on this forum it doesn't work anymore on 20H2. I've tried the solution of rename or deleting mcupdate_GenuineIntel.dll but still nothing.
In HWMonitor I can see that 6 of the cores are set 3998Mhz but when I do any kind of benchmark (XTU, Vray, Cinebench) Clock speed is 3.39Ghz.
My other question is, should Turbo Boost Max and Speed Shift be enabled (they're set to false)?
Does anyone has workaround for this issue?
I would appreciate any help.

What version of XTU are you currently running? Have you been able to previously overclock the CPU on earlier versions of W10? (i.e. or is this your first attempt at overclocking your 1680v2 CPU?)
On my Z620 (also with a 1680v2) I found that only specific versions of XTU ran on my machine, (yes, I'm still running W7Pro). I have heard of a couple of people having issues with XTU on the latest version of W10 on other forums, especially on older legacy hardware.
Here'e a link to the latest version of XTU - 18.104.22.168 (and a few previous versions); https://www.techspot.com/drivers/driver/file/information/16919/#whatsnew

Thanks for the reply.
This a new CPU I've got off ebay to replace my dual E5-2680v2. I haven't overclocked anything before.
The reason for me looking to overclock it is because single core performance is important to me, like for GPU rendering.
I'm running the latest, 22.214.171.124.
I'm gonna try to overclock it on Fedora hopefully this week, but it would be great if it was possible on Win10.

The best XTU for the E5-1680 v2 is likely to be a version written closer in time to the microcode of the processor.
I tried a number of older versions, looking up a version that was near to the release of the E5-1680 v2 and eventually settled on version 126.96.36.199 which is used by forum friends Brian195 and MothaJ. This is used in the office z420_2 as well.
An important aspect of the overclocking is the cooling effectiveness. Brian1965 uses a custom designed and fabricated external liquid cooler and was able to achieve a quasi-all core speed of 4.7GHz. On the standard air cooling, about 4.0- 4.1Ghz is possible. However, both z420_3 (E5-1650 v2) and z620_2 have the z420 AIO liquid cooler and this produced results up to 4.3GHz, but eventually it was found that 4.2GHz all-cores was more stable. The 4.2GHz is available on all cores but if the workload is 100%, the all core speed for the 1680 v2 is 3.4GHz.
If your workload is highly single thread dependent, the E5-1660 v2 is the best of the E5-v2 series as that has a higher single-thread performance plus runs 100% all- core at 3.8Ghz and 6X 3.8GHz may be better than 8X 3.4Ghz. Note in the listings below, that the 6-core E51650 v2 @4.3GHz has a higher single thread performance than the 8-core E5-1680 v2. In all cases, set the added voltage as low as possible while maintaining stability as 1.5V on the CPU over a long period will degrade the memory controller.
Passmark Performance Test is very useful for verifying the upgrade improvements.

Have you tried turning off W10's "Fast Startup" option? It is defaulted to on, caused us much trouble, is easy to turn off, does not seem to make startup fast, and one member here said turning it off got him up and running with XTU on W10 in a prior post.
The navigation is to go to the W10 Power & sleep option, click on Additional power settings, click on Choose what the power buttons do, then on Change settings that are currently unavailable, and set them as below:
