Any Benefit To Quad-Channel RAM?Posted by Joshua Jackson on March 24, 2016 at 7:54 pm
Most of the real-world tests, that I’ve seen, show very little benefit, to quad-channel RAM.
Is there anything, in Vegas, that really takes advantage, of it?

Quad-channel RAM does benchmark faster. I had it in my Hex Core workstation. I have triple channel in my 2010 Mac Pro and when I dropped it to dual channel it did benchmark slower so I switched it back. Anything that uses a lot of memory like photo editing or for 4K video will probably benefit in real life. Whether you will notice or not I haven’t actually measured. In the grand scheme of things, the speed of your RAM is usually not the bottleneck when processing heavy video FX.

“Winsat mem” on an admin command line will show your memory bandwidth as Windows sees it. You can do your trials, and in the case of quad channel memory, more bandwidth is better for Vegas.

Another thing to keep in mind when configuring a system that supports Dual or Quad channel ram, is that memory slot population can matter. On some motherboards, if all slots are populated, then chances are you will not be operating in quad channel. Only 2 sticks of identical memory per channel. Once you go to full population on the memory slots, the memory controller will drop to single channel speeds.
Dual and quad channel is also where the matched speed timings come into play. One DIMM out of timing and the controller will generally drop to single channel mode.
