Hi everyone,
I’m hoping someone can help me figure out why I can’t get my 4 x 32GB DDR5 setup stable at 6000MT/s on my ASUS ROG Strix X870E-E Gaming WiFi motherboard with a Ryzen 7 9800X3D CPU. I’ve got 2 x 32GB working flawlessly at 6000MT/s using EXPO, but when I go to 4 sticks, it’s a no-go—either it won’t boot, drops to a lower speed (like 4800MT/s), or I get random crashes. Has anyone successfully run a similar 128GB config at 6000MT/s on this board and CPU? I’d really appreciate any advice or settings you’ve used!
Here’s my situation and full setup:
• CPU: AMD Ryzen 7 9800X3D (8 cores, 3D V-Cache, released late 2024)
• Motherboard: ASUS ROG Strix X870E-E Gaming WiFi (X870 chipset, NitroPath DRAM design)
• RAM: Corsair Vengeance DDR5, 4 x 32GB (128GB total), part number CMK128GX5M4B6000C30 (6000MT/s, CL30-36-36-96, 1.35V, EXPO profile)
• BIOS: Currently on version 1203 ,
• OS: Windows 11 Pro, latest updates
What I’ve Tried:
• With 2 x 32GB in slots A2 and B2 (per manual), EXPO sets 6000MT/s perfectly—stable in MemTest86 and AIDA64, getting ~68k read bandwidth.
• With 4 x 32GB (A1, A2, B1, B2), enabling EXPO (6000MT/s) either fails to POST (stuck on orange DRAM LED)
Questions:
1. Has anyone got 4 x 32GB (especially Corsair Vengeance) running at 6000MT/s on the X870E-E with a 9800X3D? What BIOS version and settings worked for you?
2. Is this an IMC limitation with the 9800X3D, or could BIOS 1203 (with “enhanced performance” for 3D CPUs) make a difference for DDR5 stability?
3. Any specific voltages (DRAM, VDDIO, SOC) or timings I should tweak for a 4-DIMM setup?
4. Should I just settle for 5600MT/s or lower with 128GB, or is 6000MT/s achievable? And still what would settings be, because I attempted that too
I’m aiming for 128GB because I do heavy multitasking (VMs, 3D rendering, etc.), but I’d love to keep the 6000MT/s speed if possible. Any help or experiences would be awesome—thanks in advance!
