  1. Hypervisor Error after buying new CPU & GPU and enabling XMP


    Hey Community,I bought a new CPU AMD 9950x3D and a new GPU RTX 5090 and after those new Devices got detected, my BIOS got reset. After that i had to renable XMP in my BIOS but always when i activated it, after booting, my Window system crashes at start, or a few mins after start with the error "Hypervisor Error"Things i tried:- Enabling/Disabling Hyper-V- Updating BIOS- Resetting BIOS- Switched to Auto and EXPO Profiles instead of XMPI would really apprieciate if you guys could help me out with that!

    :)

    Hypervisor Error after buying new CPU & GPU and enabling XMP

    XMP enabled on Gigabyte Gaming 7 overclocks CPU


    I just got my new PC running with the Gigabyte Z170x Gaming 7 motherboard and Intel Skylake 6700k. My memory is Corsair Vengeance LPX and it's base speed is 1633. With XMP enabled it runs at 2400.

    So once I got everything installed and running I went back into my UEFI BIOS and enabled XMP to profile 1 (the only option) and the memory now runs at 2400 as expected. However, now the CPU is automatically bumped up to 4.2GHz instead of the stock 4.0GHz. If I disable XMP the overclock remains at 4.2 even though XMP is disabled and the memory is back to 1633. I wanted to run XMP but I didn't think it would force a CPU overclock also.

    I found this on another site about this issue:

    "The most troublesome "feature" of the firmware is that if you enable an XMP profile or change the memory multiplier, the CPU is automagically overclocked by applying the highest turbo multiplier—normally only used if one core is busy—to all turbo states, no matter how many cores are active. For a Core i7-6700K, this tweak means that if more than one core is active, you'll be running at 4.2GHz rather than 4.0GHz. A lot of modern boards play games like these with multipliers, but what makes the Gaming 7's behavior particularly nefarious is that the firmware shows the default non-overclocked Turbo multipliers while actually using the overclocked ones. To make matters worse, there's no single config option, say "Enhanced Turbo," that disables this behavior. Instead, you have to set the four turbo multipliers to their proper values of 42, 40, 40, and 40 manually. Nasty."

    http://www.bjorn3d.com/2015/09/gigab...0x-gaming-7/2/

    So I have no experience with overclocking. Is this bad? I just wanted the memory to run a bit faster at 2400 since that's what the box listed it as being capable of. Should I be worrying that the CPU is overclocked like this automatically? Is this normal? What else has changed in the BIOS after enabling XMP? I want all the cores enabled and I want turbo enabled also. What do I set to bump it back to stock 4.0GHz if I want to? Even in Gigabyte's EasyTune software, it now lists the default as 4.2GHz.
