So on my unraid box the dashboard displays that i have 8gb of memory which is correct, however in the next section in allocated only 4gb of that 8gb is allocated. To elaborate on this, of that allocated memory unraid tells me that its 100% utilised.

 

Any ideas on why unraid would not allocate the full 8gb ?

I too have 8GB installed, but only 4GB is allocated. 

 

TOP shows:

Mem:  3,723,496k total,  3,514,616k used,  208,880k free,    277,684k buffers

Swap:                0k total,                0k used,              0k free,  2,304,536k cached

 

Any way I can make use of the other 4GB to boost performance?

 

cheers

Nic

 

 

Are you running unraid v5?

It's also possible you have your memory incorrectly installed. A couple weeks back someone had this happen and the situation was fixed when he fixed their installation. So ... Make certain you have the memory installed in pairs and in the correct memory slot on your motherboard.
