When I open the System panel, it indicates Installed memory: Why is that? I've been trying to dig up documentation that would indicate that this is a limit of the operating system version, but I've come up short.
I've since found an infographic in the blog post titled Windows Storage Server R2 is now available! Support advised us to perform a firmware upgrade of the mainboard. We performed the firmware upgrade, but it had no effect on the issue. High end servers have options for pairing memory modules, like raid arrays for hard disks. You must view the BIOS option for that.
Have you see this link? Cause the missing RAM might be hardware reserved. It would be useful to know the exact configuration of RAM. It looks like, in order to get 32GB of RAM working on the board, you need a very specific configuration.
Many servers have separate RAM for each Processor, so if you have only 1 processor, then you either have to 1 install the 2nd processor or 2 install the RAM in the correct memory channel. Support advised us to test every module individually.
The tech on-site tested different configurations, then put all the modules back in as they were and now the full 32 GB are usable.
Also, according to the official Intel site, your particular memory is not supported for the board chipset. Then check if it requires the memory to be matched on each side of the banks i. There could be every chance the BIOS is also out of date. Sign up to join this community. The best answers are voted up and rise to the top.

As suggested by Nico, opening perfmon shows that 16 GB of memory are "reserved for hardware". Improve this question. Oliver Salzburg.

You sure the problem isn't hardware? Zoredache No, I'm not sure. But I basically asked our supplier, who we bought the server from, to send us the max amount of memory that the board could handle and they looked up the 32 GB in their database and sent them over. I'll check back with them though. Maybe check firmware versions and so on? Zoredache I'm trying to get in touch with their support, but it's still pretty early in the morning here.

I'm currently trying to gather information for tech support so that they can determine possible hardware issues. Thanks — Oliver Salzburg. Agree that the KB isn't probably the best one On Google, seems like this is a motherboard issue.
But wait for support feedbacks and update your question with their answer if possible. That must help. Alex Berry Alex Berry 2, 12 12 silver badges 23 23 bronze badges. OK - the specs of the RAM look to match the requirements for the board, from the link I sent you people have had issues with RAM that is supposedly supported and have had to change it, but their issues are different to yours they can't post.
Have you perhaps tried a linux live cd or similar, to see if another OS will actually boot with all 32GB available? I'm actually not on site, but I will do that if necessary. Sverre Sverre 2 2 gold badges 12 12 silver badges 23 23 bronze badges. Interesting theory as this server has only 1 CPU installed. Not sure if it's a dual-CPU board though. Still waiting on feedback from the client. The board is a single-socket.
Besides, if it was installed on the wrong side of a dual-socket board, the OS wouldn't even see it. I've run in to this with another Intel board. In the BIOS, 2 of the modules were marked as "failed". Not really sure what to make of it.
That would have saved you some time and allowed us to rule out Windows immediately. Care to name a software? As I explained already, I wasn't on site, otherwise I would have. Surely the person who performed the firmware upgrade could have. But whatever. Show 2 more comments. First thing I'd do is return the RAM back and get certified modules supported by the vendor.
