Overclocking HP Z440 with a Xeon E5-1650v3 processor

[Moron666]

We recently purchased an HP Z440 with a Xeon E5-1650v3 processor for use in out engineering dept. Yesterday we were able to overclock it to 4.2 ghz using the Extreme Tuning Utility. When the user started up this morning, the controls were back to default and some settings are now greyed out.

Does anyone know who the OEM for this board is, I want to find an unlocked BIOS and overclock from there.

This is info from the motherebaard UPC Sticker:

The HP Z440 uses a motherboard designed by HP specifically for the Z440.  It is not a third-party board that is sold elsewhere. 

The Z440 BIOS was developed by HP specifically for this system.  HP does not support overclocking, since it could potentially reduce the system's design life goals.

It is interesting that you managed to overclock your HP Z440 using Intel XTU. I have tried installing this on a Z420 with a Xeon E5-1650 v1 (itself an unlocked CPU) however all the tuning options are grayed out.

SInce you managed to get it working - albeit briefly - maybe its worth trying older versions of XTU or using the version which you previously installed, but turning off any automatic updating of the utility (if that is possible).

I have read reports that sometimes using older versions unlocks manual tuning options on certain mother board / CPU combinations, which are then 'blacklisted' in subsequent updates.

AFAIR Intel does not host the older versions of XTU, they are however available on various overclocking / bios modding sites.
