Precision Workstation T5400 processor upgrade to support SLAT therefore Hyper-V

Hi,

I have a Dell Precision Workstation T5400, my current processors are:

Processor(s): 2 Processor(s) Installed.
[01]: Intel64 Family 6 Model 23 Stepping 10 GenuineIntel ~3000 Mhz
[02]: Intel64 Family 6 Model 23 Stepping 10 GenuineIntel ~3000 Mhz

more specifically

Intel(R) Xeon(R) CPU E5450 @ 3.00GHz 3.00GHz (2 processors)

They do not support SLAT(Second Level Address Translation) which is a requirement for Hyper-V to work:

Current Hyper-V Requirements:

VM Monitor Mode Extensions: Yes
Virtualization Enabled In Firmware: Yes
Second Level Address Translation: No
Data Execution Prevention Available: Yes

Could I please have some advice on what processors would be a natural upgrade for me, which support SLAT?

Thanks
