# msr-cmd, msr-watchdog | ||
|
||
------ | ||
|
||
Two little utilities to set and keep Model Specific Registers (MSR) as you like without any painful experience with using other things like ThrottleStop (this thing leaves a stupid icon on taskbar not notification icon when runs in background, and it resets some settings like C-States when launches) or dumb OEM overclocking tools. | ||
|
||
------ | ||
|
||
For example, my Xeon E5v4 does not set maximum uncore (cache) clock (results +5%~10% cache performance) by default, and it's unable to tweak via UEFI. Figure out the the uncore clock multiplier MSR register (check out Intel Software Developer Manual) and use **msr-watchdog** to set and keep its value on the fly (as a daemon). Because suspend or resume system will reset the MSR registers. | ||
|
||
Also, it can lock MSR mailbox registers (some relate to voltages), too. These values like voltages settings can be yielded from ThrottleStop. | ||
|
||
**msr-cmd** is something like **wrmsr** from Intel msr-tools in Linux world, which can be used in batch scripts. | ||
|
||
All these utilities are based on WinRing0 driver, no WDK is required. | ||
