Issue with DRR5 during operation of four dimmers at 6000MHz causing a blue screen
Issue with DRR5 during operation of four dimmers at 6000MHz causing a blue screen
I possess two sets of 32GB RAM, each with 16GB per slot, totaling 4800MB. I'm unable to exceed 4800MB without encountering a blue screen. I've observed this issue before and am considering updating the BIOS to version 805. Previously, my system ran smoothly at 6000MHz with both kits, but after adding another 32GB (16+16GB), it only functions at 4800MHz without errors. My motherboard supports XMP profiles, though I haven't tested newer Intel technologies since I purchased these a short time ago. The 64GB model doesn't work at 6000MHz, only at 4800MHz in MemTest86. My current setup includes an Asus Rog Crossair Hero X670E with the Ryzen 7900X graphics and Corsair Vengeance DRR5 RAM (6000MHz, 64GB). PSU: Corsair RM1000X Full Modular 80 Plus Gold. Please advise if this configuration is acceptable.
4 Dimms aren't compatible with XMP/EXPO on Ryzen 7000 chips. For 64 GB, opt for a 2x32 configuration. Even Intel 12th/13th gen models may face issues with 4 dimms installed. They're usually rated for at least the bare minimum specs, which supports 4800 speeds. Is there a particular reason you need 64 GB?
Because model numbers match doesn't guarantee identical parts. RAM makers adjust contents in each speed category based on their inventory that day. A 6000 CL36 should reliably fit Samsung 16Gb B, though Corsair might have altered it slightly. Verify the version codes on the modules to confirm consistency. Consider these adjustments: tweak the BIOS revision, as AMD systems often lose memory support after BIOS updates; experiment with different revisions. Play around with IMC voltages—there are two key values: SOC and MC. For Ryzen 7000 chips, maintain the same MC voltage as the memory (typically 1.35V), while you can vary the SOC voltage. Aim to keep it under 1.4V for CPU health, but pushing it higher usually leads to worse FCLK overclocking. Begin at 1.3V and increment by 10mV until stability is achieved.
Have you never adjusted the voltage settings before? Is there a tutorial video available to guide you? You might want to revert to the 805 version.
You haven't encountered anything similar before, but it's actually quite manageable. Open the BIOS menu and look for a parameter like "SOC voltage," "VDD_SOC" or "vSOC." Adjust it to 1.3V and attempt the test again with 6000 MHz. If successful, proceed. If not, incrementally increase by 10mV (1.31V, 1.32V, etc.) until stable at 1.4V. If reaching 1.4V remains unstable, consider lowering to 5800MT/s and retrying at 1.3V. For more details on memory tuning, check the Igorslab guide linked—though it applies mainly to ASRock boards with similar changes in setting locations.
When versions match and individual sticks passed memory stress tests, it suggests no hardware problems. Likely the memory controller is the bottleneck; raising the SOC voltage may be necessary unless the BIOS update succeeds.
I’m currently traveling for work. When I return, I’ll try it out and update you here. Please mark it as a solution if it works. Thanks for your time!
Earlier discussions noted that achieving higher frequencies with those four channels is unlikely, especially on modern DDR5 systems. Operating them at speeds above 5600MHz would be challenging and would significantly restrict performance.
