![]() ![]() I use to have locked Intel Xeon Ivy Bridge processor tried using a similar setting on a Z77 MSI motherboard, and observed the same behavior with clock speed fluctuating even when the processor was idle. ![]() Have done this and i get to 3.6ghz every few seconds but it is fluctuating from 33-36 multiplier which is causing the cpu to jump every few seconds between 3.3ghz, 3.4ghz, 3.5ghz and 3.6ghz in a random order. any idea what obscure UEFI setting it is that i am missing? i am running video off of the integrated intel cpu graphics, could this be the issue? i guess i can test with a spare videocard but this build is for a client and they did not want an separate gpu. I have literally spent days trying everything in the UEFI and i am at a loss here. i have it tried setting it per core and to sync all cores also with no change. i have disabled c states but that will freeze the cpu at 3.3ghz without any fluctuations. i have tried setting cpu vcore to manual level of 1.2v instead of auto with no change. i have tried almost every UEFI option regarding cpu throttling and it doesn't matter. I have windows power options set to high performance. ![]() my temps are all within normal ranges so it doesn't appear to be a temp throttling issue. i have done this and i get to 3.6ghz every few seconds but it is fluctuating from 33-36 multiplier which is causing the cpu to jump every few seconds between 3.3ghz, 3.4ghz, 3.5ghz and 3.6ghz in a random order. asus has a UEFI setting called multicore enhancement which is suppose to accomplish this if you enable an XMP profile and set multicore enhancement to auto. So i want to run at max turbo speed of 3.6ghz all the time. ![]()
