hi,
you need to enable "winrm" Service on Remote PC
try Powershell on Remote PC and check with
If it is stopped, type:
Add access permission to the remote host.
winrm s winrm/config/client '@{TrustedHosts="REMOTECOMPUTERNAME/IP"}'
REMOTECOMPUTERNAME = Name "see" under Network
IP = 192.xxx.xxx.xxx

also Windows Firewall is blocking the Remote Access.
goto Firewall and select WMI

when all is enable try
get-wmiobject CIM_Memory -computername "192.xxx.xxx.xxx" -credential "username"
you will ask for Password ... and hope now you got access of Memory Information
