HWinfo does indeed show the correct values. Thank you for the help in clarifying what we were seeing.

Having issues with a Haswell cpu in combination with a 2x16GB kit's memory profile on a friends pc. Motherboard: Gigabyte GA-X99-UD3 (rev. 1.0) Bios: F23c Memory: G.Skill F4-3000C16D-32GISB CPU : Intel i7 5820K With XMP disabled the CPU runs and boosts fine and it can utilise to 100% 2100 15-15-15-36 But when I turn on XMP (only 1 profile) the cpu stops going over 2.9Ghz and running Cinebench R20 or Prime95 the utilisation doesn't go over 90%. Picture from running CinebenchR20 PS: I did actually notice it said 3751Mhz CPU clock on MSI Afterburners monitor now that I'm looking at the pictures while inserting them. We've tried setting the frequency, timings and voltage of the XMP profile manually, but that resulted in not booting at all. 3000 16-18-18-38 1.35v We've tried setting it to 2600 16-18-18-38 1.35v After that we noticed that the XMP profile (only 1 profile available) sets the Processor Base Clock Multiplier to 1.25 (125Mhz) instead of the default 100Mhz. Manually lowering this to 1.0. Which resulted in the memory frequency going down to 2400Mhz since that's the base multiplier. Currently we're just running the system without XMP or any manual overclock. But to me it's very weird an XMP profile would up the base clock by that much and in turn having utilisation issues. Picture of default values with XMP enabled. I'm confused on what is happening here. So here are my main questions at this moment: Is taskmanager just by default basing everything on a 100Mhz BCLK? And would that also explain the 90% utilisation.? Am I correct in the assumption that it actually all works fine with XMP enabled and taskmanager just gives wrong information here? -And if so is there something one can do to change the BCLK for taskmanager? -If not what can we do to actually get a higher speed than 2133
