4 DDR5 modules clocked at 3600 MHz versus 4800 MHz
4 DDR5 modules clocked at 3600 MHz versus 4800 MHz
I rely heavily on Adobe After Effects, focusing mainly on CPU speed and RAM size. Initially, I had 64 GB (two 32 GB modules) on an MSI X670-P WiFi board with a Ryzen 7950X. In Windows Task Manager it showed 4800 MHz. I upgraded to two more sticks for 128 GB, but now only 3600 MHz runs when all four are connected. Is this normal? If not, can I boost performance to match the original speed without turning on EXPO? The specs I have are: RAM link: https://www.amazon.com/CORSAIR-VENGEANCE...B0BLYL79TT Motherboard link: https://www.msi.com/Motherboard/PRO-X670...cification
Four sticks struggle to match the speed and timing of two sticks using DDR5. Reducing MHz is often necessary to achieve similar performance. Two sticks can operate in quad channel, while four may need 6000MHz but only 3600MHz with DDR5. A BIOS update could improve things. Updated video available for review.
It's normal for the system to behave as expected, since it's not posting with XMP profiles. The RAM is designed for those speeds, but the processor doesn't reach 4x1R or 4x2R—this is the highest memory frequency you'll get, and anything beyond isn't reliable. Occasionally, a BIOS update can boost stability, allowing you to hit 4800MHz. You might also attempt manual frequency and timing settings, though success isn't guaranteed and clearing CMOS could be necessary.
