Motherboard/OS only recognizing one CPU

[PeeR_SaBBi]

Hi all! I bought a server and I've been working around with it, simply tweaking the BIOS settings, and downloaded Windows 10, and VMs of server 2008 and Kali Linux. when in task manager, it only recognizes one CPU (spec list below), 4C/8T, it recognizes all 16GB of RAM in POST and OS, even as independent modules (2x4GB per each CPU). What could be the problem? I'll answer any questions you may have.
Spec list:
CPU: 2x Intel Xeon X5550
Mobo: Tyan S7012 dual socket LGA1366 (Tylersburg 5520 chipset)
RAM: 16GB of ECC Registered RAM (2 dimms per CPU of 4GB independent to each CPU, i.e. not mirrored)
PSU: EVGA 650 G2
HDD: WD Blue 1TB
GPU: Sapphire R7 240

Is the Linux multi-cpu aware ?

Have you though about using ClearOS as your VM host ?

Hi,
Several ideas here: https://www.storagecraft.com/support/forum/only-1-processor-showing-task-manager
Check msconfig, try reinstalling Windows, updating the BIOS.

Do you think BIOS settings could be the issue? I've been looking at some stuff in the settings such as the server type prefetch (either HPC, enterprise, or custom), which do I choose?

It's performance related, I don't think that it can help. What options getting with custom?

I'd assume custom makes it similar to HPC, but focused on security as well.
I've used msconfig, to no avail, and I've disabled max CPUID limit, which didn't help either

What Windows using?

I'm not sure what you mean, but I'm using Win10?

Home, or Professional?

Home, or Professional?

Home on this install, I only had a home key, although if needed, I can just install pro.

Home does recognize only one CPU, AFAIK.
Try with PRO and see if still the same.

Thank you! I'll install pro right now. If it works, I'll tell you.

 

[alexoiu]

Yes, please post back the result.

 

[PeeR_SaBBi]

It worked! All 8C/16T showed up. Thank you so much!

You're welcome. Thank you for confirming it.
