Author Topic: Will the same amount of DDR4 increase visibly SD speed over DDR3  (Read 546 times)

Im upgrading my pc from ddr3 motherboard to ddr4, I have and will have modest 16gb, in around the same speed of 2300GHZ, will i see any difference in performance of SD graphs? I often run out of memory and have to use scratch disk memory

Hello @bugajskimaciek,

Thank you for reaching out to us!

The increased clock speeds from DDR3 to DDR4 will provide some benefit in the overall responsiveness of Substance Designer, but the issues linked to memory shortages will persist as the actual available pool will likely not change much.
If the system runs out of memory and hits the pagefile, the usual recommendations still apply:
  • Close any other memory intensive application
  • Disable the Image cache for the graph – the option is available in the Graph toolbar
  • Increase the Engine memory limit in the General section of the Preferences window
  • Increase the system memory pool
I hope this will help you make the most appropriate choice for your use case when selecting the parts for your new system.
