I upgraded my RAM from 8GB to 32GB, but there is no improvement in encoding speed

Hi,

I have been using media encoder for a while now.

I initally had 8GB memory on my laptop, which houses a 4 physical core (8 logical ) core CPU.

I usually encode videos at 4k resolution for uploading to Youtube.

I recently opened up my laptop to upgrade to 32GB RAM.  It has made my system more fast, when using Adobe Apps.

However, I see no speed up in the encoding of my videos.   I have a 13 minute video currenly beinfgencoded at 4K,  It says the estimated time is going to be 7 hours.

I opened up my Resource Manager, and I see the system is only using 49% of the CPU, and only  47% of the memory, and 3% of the disk while the encode is going on.

There seems to be a lot of horsepower in the machine that is going under-utilized while encoding with Adobe Media Encoder,, what should I do to get maximum resources to be used solely for encoding.

Additional info:

I have CUDA enabled GPU, with the latest NVIDIA drivers,  my GFX discreet GPU is GTX Geforce 1050.
