HP Microserver Gen8 Processor FAQ

Recommended Posts

LoneWolf

Note:  Something I did not realize until working more deeply today when replacing my Gen8 Microserver's processor.

 

If you *do* wish to use Bitlocker or some other types of hardware encryption, one of the general requirements is having a system with a TPM (Trusted Platform Module).  Plenty of modern enthusiast mainboards have this; the Microserver Gen8 does not.  It is a purchasable option, with a general price of around $45-50.

 

HP's part number is 488069-b21, which is meant for broad compatibility across the Gen8 line of servers.  The part is a small daughtercard  that connects to a TPM connector on the mainboard.  As part of the procedure, a plastic rivet is also used in the installation.  This rivet holds the TPM in place, and is designed to deform or break if the TPM is removed, to make you aware that security has been breached.  Once the TPM is attached, it is paired to the mainboard for life, and should not be removed.  Should HP need to replace your mainboard under warranty, you should notify them that you have a TPM so they may provide you with a new one for the new mainboard; the original TPM should remain paired with the original board, per HP's own instructions.

 

The AES New Instructions are still useful in some other applications, but if you are looking to do full disk encryption, you will wish to purchase the TPM module as well.

Two additional "should-work" processors:

 

Intel Core i3-3220T (2.8GHz, 2 cores, 4 threads, 35w TDP, Ivy Bridge)

http://ark.intel.com/products/65694/

 

Intel Core i3-3250T (3GHz, 2 cores, 4 threads, 35w TDP, Ivy Bridge)

http://ark.intel.com/products/74745/Intel-Core-i3-3250T-Processor-3M-Cache-3_00-GHz

 

These processors are among the rare subset of Intel desktop CPUs that support ECC memory; you could think of them as very stripped-down versions of the Xeon E3-1220L v2.  Both of these processors lack Intel VT-d, so they're not super choices for VM hypervisor work; unlike the Xeon, they also lack Turbo Boost dynamic clock scaling for higher single-threaded performance.  They do bring Hyperthreading and QuickSync to the table.  If you're buying a brand new CPU, they wouldn't be on my list as you're already partway to the cost of a new or used Xeon E3; however, if you're pulling one from another system or come across one cheap, they will improve performance over the original processors.

I can verify that the Intel Core i3-3220T works fine - had one available so I upgraded a  G1610T Gen8.. (been running for 4 weeks with that, plus -16Gb of Kingston ram, a 2.5" ssd with server 2012 installed, 4 3Gb WD Red HDD's, and the HP DVD drive.)

Too bad your hard drives are so small ;)  (sorry, couldn't resist) :D

Sweet, Joe!

 

I've had my 1265L v2 for about a month, it's been a great upgrade.  I do think it is probably the best CPU upgrade for the MS Gen8, followed closely by the 1260L, and then (if low power is a concern) the 1220L v2.
