Issue appears when turning on XMP settings.
Hi, I’m experiencing a black screen when enabling XMP. This has happened before on my previous Ryzen build too. Is XMP actually not compatible or something? I have a RAM setup of four 32GB modules with Corsair Vengeance DDR5 at 5600MHz. The motherboard is Pro X670 with Wi-Fi. I also used an X370 board and Ryzen 3900 before, and I never ran into this issue for nearly five years. Could you help clarify? Thanks!
The updated Ryzen processors offer significantly varied memory speeds depending on the number of slots connected. Check the official page for details: https://www.amd.com/en/products/cpu/amd-ryzen-9-7950x
I wasn't aware of this! It's really bad, especially since I usually upgrade every five years and memory speed is important for my tasks. It looks like large datasets will run slower than DDR4 for me. Can I get an overclock fix or should I consider returning the Ryzen?
If you really need 128GB and high bandwidth, then Ryzen 7000 isn't ideal right now. It's possible future AM5 chipsets will improve this, though they might only be available in professional builds—similar to Intel with ECC support. I currently run two 32GB CMK64GX5M2B5600Z40 units, which work fine and are EXPO compatible; the only issue has been slow startup times. It wasn't chosen deliberately, just the only EXPO kit offered at launch. I'm considering a upgrade to 128GB later, but probably not.
I managed to achieve a stable performance with the kit at around 5200, but I'm experiencing extremely slow boot times—often taking about ten minutes. After that, it runs smoothly in Windows.
Be mindful to avoid confusing stability with data integrity when handling crucial datasets. Gamers usually don’t worry, but you might. DDR5 supports ondie-ECC, though it doesn’t handle dedicated ECC channel errors, but it performs better than anything else. I just upgraded my BIOS to the beta release a couple of days ago, and boot times have noticeably improved—possibly because EXPO was initializing more frequently. Plus, several issues I faced seem to have been resolved automatically. If you haven’t updated yet, consider doing so.
