Ram bandwidth improvement with 8channel memory?

[lourendo]

Hi, how much does memory bandwith affect performance? I'm in the process of building my new rig and I'm considering moving to a cpu with 8 channel memory support. I'm currently running a i9 14900k with dual rank, 2 channel 64gb 6400Mt/s ddr5, with a pice 4.0x4 NVME and I'm still having lagging and program lockup issues, especially when copying/pasting multiple complex symbols. Watching the system monitor when it's frozen, I will see the memory usage slowly increase, once it stops rising it will unfreeze.  This leads me to believe it's my memory bottlenecking the program.  

 

If I were to make a system with single rank ram in 8 channel operation, I would theoretically x4 my bandwidth and also increase my per channel speed since it's only 1 rank per channel.  If my lagging problem is due to insufficient memory bandwith, this should cut my lag times by 1/4,  300% improvement.  

 

Hopefully someone that knows how the program handles memory management and operations can give some insight into my problem.

 

The cost would be significant to build an 8 or 12 channel system, but it would be worth it, assuming it would actually increase my performance.  The real question is whether or not I will see any benefit. 

 

Does anyone have experience with quad or 8 channel memory? Does it offer any improvement?   Thank you.

Im still seeking some clarity on this as it is still an issue. hopefully someone from Vectorworks can help.  I would love to know if this would be an effective strategy to improve my performance.  Thank you

Yes is anyone at home at Nemetcheck?

The hardware channel does not get much love.

I am about to build a new rig as well and this question of memory bandwidth is high on my list.

My current machine is still well within the specs of High End, but it struggles with things like copy and paste, and I think it's a memory bandwidth issue, or some kind of memory chocking on my motherboard.

I agree, but i dont want to spend $10k on a huge rig and then not see any increase in performance, my cpu only runs at 2-3% at 5.8GHZ so any upgrade to CPU seems like a waste of money unless unlocking memory channels which is ambiguous.
