NOTE: If AMT is disabled you will not see the Watchdog Timer settings.ģ) Enable Turbo Mode and ensure the Legacy ACPI CPU Tables are enabled. I'd really appreciate, the insight, thanks in advance.Īlso, here's a screenshot of the bluescreen and all the XTU versions I've tried:Ĭan you first please re-confirm that your BIOS settings are set as follows ġ) Ensure PCIe Performance Mode is disabled.Ģ) Ensure that AMT is enabled and also the Watchdog Timer, the BIOS and OS Watchdog Timer settings are set to 5 and 5. I noticed OP's original post mention's he's on Win 7 for an OS, and this was back in 18', hopefully its not an OS compatibility issue.Īny suggestions, anyone able to overclock their Z420 while on Win 10? Mention success with overclocking a Z420 with XTU, however I'm having no luck with Windows 10.

I know some of the guys over at this thread: With some versions, moving the multiplier sliders doesn't do anything at all, in other versions moving the slider and hitting apply yields a bluescreen with 'iocbios2.sys' marked as the culprit (yes I know its the XTU driver but that doesn't help me). However, no matter which version of XTU I try, I can't get it to work.

System has 64 GB of Hynix DDR3 1866MHZ Unbuffered RAM, & a GTX 1070, so its no slouch. The CPU I am trying to overclock is the Intel E5-1650 V2, on a Z420 running Windows, all latest patches.

Business PCs, Workstations and Point of Sale SystemsĬan someone please let me know the version of Intel XTU they are using on an HP Z420 to overlclock their CPU?.
