RAM and power supply capacity are analogous insofar that if your usage does not overtax them, then increasing them will not give you benefit. My workstations have power supplies of 1,100W or more, but I run two CPUs per chassis, extra fans, and liquid cooling for some things.

If your memory usage is pegging, then that is your performance bottleneck. How many RAM slots do you have? Are they all occupied? What type of memory is in them?

If you don't know the type of memory, you can go to Piriform.org and download the free Speccy (CrapCleaner and Defraggler are also good). Install and run Speccy, and it will give you the specifications. This is the summary for my little midtower workstation Urania:

Urania uses DDR3 with 9-9-9-24 timing. There's more specific info needed before matching memory sticks, so I expand the RAM heading...

Urania's type of DDR3 is more specifically PC3-10700. That's registered (server) memory. She has six DIMM slots; all of them filled with an 8GB DIMM. When adding memory, you need to match the DDR type, the PC3-12800 or other type, the timing (9-9-9-24, e.g.), and the clock speed (667MHz). If replacing all of the memory, you may have several options which are available; there will usually be about four different clock speeds to choose from, and many server motherboards can use either registered or unregistered memory.

If you note the model number of the motherboard, you can go to the manufacturer's website and look up a list of what types of memory are compatible.

====================================

Queue works fine for me. Install/run DLM on each slave; enter the Queue serial (not the Poser Pro serial). The first time you run Queue on slave units, you will need to OK firewall permissions, usually once when Queue first begins "announcing" it's availability over your network, and again the first time it needs to return a finished render pass.

Limitations: Queue will only distribute complete frame passes - it does not distribute a single render frame across a network (that's #1 on my Poser wishlist!) Queue is currently only enabled for Firefly.

Still, this can allow you to send off promo/test renders to slave(s), freeing up your main computer. For animations, it's a huge advantage, because the 500 (or whatever) frames will be dealt out among all of your machines. Every time a machine finishes a frame, the master will send it the next frame waiting, until all the frames are completed.
