DL140 speed step problem


I have DL140 G2 machine running CentOS Linux.
Unfortunately I cannot use speedstep technology. Does anyone know if there are any issues or if motherboard does not support it?

My CPU model:
SL7ZC , 3.6GHz Xeon, fsb 800MHz.
According to documentation it should support it.
Any ideas?

Thank you for help,

Re: DL140 speed step problem

Hello Jacek,

SpeedStep is an INTEL proprietary.
Look at the CHIPSET required for this feature, as mentioned by intel:

DL140 G3 has a Intel Chipset E7520 with 800MHz Front Side Bus, which DOES NOT meet the criteria;
Refer: http://h18004.www1.hp.com/products/quickspecs/12205_div/12205_div.html

Again, as per intel,
There are no 3.6Ghz processor that will support SpeedStep;

As per HP, DL140 G2 will support:
* Intel Xeon 3.6GHz processor with 2M L2 Cache
* Intel Xeon 3.4GHz processor with 2MB L2 Cache
* Intel Xeon 3.4GHz processor with 1MB L2 Cache
* Intel Xeon 2.8GHz processor with 2M L2 Cache
* Intel Xeon 2.8GHz processor with 1M L2 Cache

& only the 2.8Ghz with 2MB L2 cache fits this Criteria, PROVIDED the Chipset is a match;

Hence, Clearly, as per my research, SPEEDSTEP CANNOT be achieved in a DL140 G2;
