Two distinct sets of frequency RAM DIMMs might lead to issues if not properly aligned.
Two distinct sets of frequency RAM DIMMs might lead to issues if not properly aligned.
Hello everyone, I'm facing a challenge with my current setup. I have 32GB of RAM for video editing and animation, using Corsair Vengeance RGB PRO 32GB (2x16) DDR4 at 3200MHz. Previously, I had Corsair Vengeance LPX 16GB (2x8GB) at 3000MHz. If I were to add the older sticks, could it affect stability? I think I'd need to adjust the newer memory speed to 3000MHz, but there might be other changes required since the memory types differ (C16 vs C15). My system includes a Ryzen 7 2700X, AMD Radeon RX590, ASUS ROG Crosshair VII Hero X470, and I'm using DaVinci Resolve 17.1 and Affinity Photo.
You might attempt to run all RAM simultaneously at the slowest common speed, such as DDR4-3000 CL15. It could succeed or fail—just experiment to determine. Keep in mind that DDR4-3000 CL15 matches the latency of DDR4-3200 CL16 by a factor of 10ns due to the calculation. Be sure to examine other timing details carefully. You can reverse calculate the exact latency in nanoseconds for each setting and adjust accordingly.
Don't worry about what was said. Proceed with running memtest86 through all four passes. For extra assurance, also execute the HCI Design memtest. Using the HCI Design version, perform 16 tests—one per CPU thread—each handling 2.25GB (totaling 75% of your 48GB RAM) and aim for at least 300% completion.
I’m not sure, but I’ll try my best to answer. It depends on the specifics, but generally it shouldn’t cause more harm than normal.
I think the presence of those features in the BIOS comes from the fact that my ASUS ROG Crosshair VII Hero has an ASUS ROG Crosshair VII Hero Hero. The way they are named, placed, and displayed is what could be causing the confusion. I usually only adjust XMP settings at first, or something similar to AMD’s equivalent.
I might be able to exchange with someone for the identical RAM kit—3200mhz C16 instead of the 3000mhz C15. It would remain Vengeance LPX, matching the current Vengeance RGB Pro, offering similar speed and latency. Should I think about making the trade or stick with my current setup? Also, if I do trade, I should definitely run all the tests to confirm DIMMS compatibility.
