Hi Daniel,

Did you find that processor ?

Do you have any update about it?

Thank you

Thank you

I was not able to locate this processor in the lab here, so I will have to coordinate with another group. I should be able to find something out by the middle of next week.

Thanks

Hi Daniel,

Do you have any update? We are considering to buy a number of new DELL servers through local vendors.

If you can provide us some confidence results earlier, it can help us to make the decision of buying servers earlier.

Thank you.

I apologize for the delay. We didn't have any of those processors in our labs. We are expecting a delivery of them tomorrow. Once we have them installed we can verify whether or not DPAT is fucntional, and whether or not any additional steps are required with the V2 CPUs.

While we are waiting I would recommand installing turbostat if you don't have it already. I think it is part of the cpupowerutils package in RHEL. It will provide more detailed information on the processor states and frequencies.

Thanks

The processors did not arrive on schedule. I'll update you when we get them installed and are able to test.

Thanks

We have received the CPU and tested. It is functional.

What we did find is that dmidecode is not useful in checking frequencies. Turbostat accurately reported the CPU frequencies with DPAT enabled, but dmidecode still reported 3300 and 3600 like you are seeing. Please install turbostat and check the frequencies using it.

Thanks

OK, I will install the turbostat and tested it again.

Daniel, Just for our reference, what result you saw with turbostat before and after DPAT on R620 with 2667 v2 CPU ?

Daniel, Just for our reference, what result you saw with turbostat before and after DPAT on R620 with 2667 v2 CPU ?

With 2 cores enabled turbostat was listing 3.90GHz. dmidecode was still listing 3.3 base and 3.6 current.

Thanks
