Hello,

I have an OptiPlex 7050 Micro (Core i5-6500T) which will only run at 790MHz. Way off from its designed speed. It is running Windows 10 Enterprise 1809 x64. All drivers and BIOS updates have been applied and are at their latest versions. Intel SpeedStep has been disabled in the BIOS. Reverting the BIOS back to factory configuration has done nothing as well. This unit is one of several identical machines in service, but the only one with this problem. Is there anything else I can try, or is this a warranty issue?

Thanks
