I recently order a server with [Intel(R) Xeon(R) CPU X3440 @ 2.53GHz] processor. But when I check Server information under Cpanel. I see speed way less that 2.53GHz take a look: Is that thing okay? Because its not even close to 2.53GHz.. Please advise.
I'd just say it is a misreading by your programme or by the BIOS. It does show as a Genuine x3440 and is showing 8 cores (actually a Quad Core including Hyper-Threading) so I'd say there's nothing to worry about.
Mailbox server capacity planning has changed significantly from previous versions of Exchange due to mailbox resiliency provided in Microsoft Exchange Server 2010.
Its absolutely correct. Its for power saving. When required, your processor will clock faster than what is showing. There is no need to worry about it and its perfectly normal
