Installeer extra geheugen HP ProLiant

Waarom extra geheugen toevoegen ?

De hoeveelheid geheugen die standaard word meegeleverd is niet voldoende om de HP server te gebruiken. 2 GB's is absoluut niet genoeg wanneer je wil gaan virtualiseren of zware applicaties wil draaien.
Om de kosten te reduceren, installeren we standaard consumer geheugen.

Welk type geheugen hebben we nodig ?

De HP server ondersteund de volgende geheugen DIMMS:

Unregistered/Unbuffered Memory DIMM's
- ECC UDIMM's : komt nauwelijks voor
- UDIMM's : consumer memory
Registered/Buffered Memory DIMM's : levert extra data consistency
- ECC RDIMM's
- RDIMM's

In this case; the server machine is for testing purposes only. so we won't need expensive RDIMM's. We'll just take the cheap UDIMM's.

Hoeveel geheugen hebben we nodig ?

as much as possible:
The motherboard has 3 tri-channels this means that there are 9 memory slots.
To highest amount of UDIMM memory you can install is 12 GB ( 6 x 2GB ). This is far less than the amount of RDIMM memory (144GB ECC RDIMM's in 18 slots) that you can install. As you can see the maximum memory amount per slot is 2GB and you can only use 2 of these three memory channels.

Selecteren van het juiste geheugen

You need to select the following specifications :

DDR3 : The server only supports this type
1333MHz ( = type PC10660 ) or higher should work too but is more expensive... you'll probably be able to decrease latencies when using faster memory.
tri-channel in order to have 3 DIMM's that are perfectly in sync
2GB / UDIMM ( the maximum that is supported for UDIMM's )
Max. 6 UDIMM's ( the maximum )

...so I've found the following :
Kingston HyperX 6 GB DDR3-1333 Tri-Kit (Light-Retail, KHX1333C7D3K3/6GX, Genesis, XMP)
I've ordered 2 - tri-channel kits @ http://www.alternate.nl

Installatie

Now, fingers crossed...
Yep, it works fortunately !
...altough I've received errors from the BIOS. it says...

After this screen, the BIOS Memory testing screen comes up. This should happen every time you've changed the memory configuration. It keeps saying "testing memory for Processor 1 ..." after half an hour without seeing any progress, I've rebooted the machine and it came up without a problem. There is just some extra noise from the cooling fans.

Unfortunately you can't do anything about this noise.
