Xeon E5-4650 and TurboBoost

TOrti — Thu, 15 May 2014 17:56:27 GMT

Hi has anyone been successful in overclocking the Xeon E5-4650 Processor to advertised speed of 3.3Ghz.

I been adjusting Bios settings on or IBM x3750 server and only gotten up to 2.9Ghz.

OS is RHEL 5.9 64-bit

HI tortiz96, the Intel® Xeon® Processor E5-4650 has a default clock speed of 2.7 GHz and it can reach a maximum turbo frequency of 3.3 GHz. This means that the processor will use Intel® Turbo Boost Technology to increase the clock speed up to 3.3 GHz automatically and depending on temperature, voltage, power, load and amount of cores being used. This could mean that the processor will increase to 2.9 or 3.1 GHz at some specific moment and not necessarily reach the maximum.

Intel® Turbo Boost Technology is not the same as overclocking since the first one is managed automatically and it is not on-demand or user controlled as overclocking is. Only unlocked Intel® Core processors (which models end in K or X) can be overclocked.

At this time we only offer the http://www.tcsscreening.com/files/users/IPDT_LiveUSB/index.html Linux* bootable version of the Intel® Processor Diagnostic Tool.

However, it may be possible to find some applications created by Linux* community members but we cannot guarantee their functionality: http://ubuntuforums.org/showthread.php?t=1635241 http://ubuntuforums.org/showthread.php?t=1635241

Does this tool work on Multi-processor systems. We have a ibm server with 4 physical CPU's. Thanks

Also will the tool work on Intel XEON E5-4650. Thanks

All Intel® processors released in recent years are supported by this tool. It also supports Multiprocessor systems.

Hi does an unlocked Intel Xeon processor exist?
