Windows Reported RAM does not match Task Manager Reported RAM

I came across this today while doing the latest round of windows updates. See the attached screen shot.

The properties show system Memory at 48.0GB, but the task manager Physical Memory shows 32767 MB.

To the best of my knowledge 48GB should convert to 49152 MB.

Any idea what's going on here? This is an HP DL 380 G6.

Ideas?

That's a limit of your OS. Windows server standard supports a maximum of 32GB (at least the 64 bit versions of 2003 and 2008 Server Standard). The crucial link below shows the limits of further Windows OS's:

It seems that 48GB is installed on the motherboard, but 64-bit Windows server 2008 (R2) Standard has memory limit set to 32GB

Thank you all. That didn't even occur to me. Looks like an edition upgrade is in order.

Thanks for the quick responses!

You could also move up to 2012 essentials (64GB), or standard (4TB). Either are probably cheaper than changing just the edition but staying on the old OS version.
