recently i got a strange issue, the xeon e5 2670 only clocking at 2,6 ghz fixed, they are not going in turbo mode
(3 ghz or 3,3 ghz) at all anymore, not even under heavy load on all cores.
recently after purchasing the workstation, it worked without problems.
temperatures are normal, even under load only 72-75°C.
what could that be? theres a bios setting called turbo mode, but i cannot switch that to "on" when PCI-e performance mode is enabled. i don't understand, why pci performance mode deactivates the option to switch that turbo mode.
bios version is the newest, also the drivers all are up to date.
yesterday, i installed the hp performance advisor, strangely, i can set the turbo modus in the bios setting there and save the profile, but after reboot, it is deactivated again.
currently, hyperthreading is set to "off" in bios due to some compatibility issues with certain software,
but i tried this with switched to "on", and it has no influence on the max. 2,6 ghz speed.
by the way - what is the CECP mode in bios?
best greetings and thanks for any hint
Chris
Set PCIe performance mode to off in the bios - you will then get your turbo back.
Turn CECP to off - its some kind of power saving feature.
Make sure your power settings in Windows are set to maximum performance.
