Experiencing difficulties reaching 3600Mhz memory performance
Experiencing difficulties reaching 3600Mhz memory performance
Hello, I just upgraded my PC by changing from Intel to AMD New Mobo: X570 ROG Crosshair VIII Hero CPU (3900X). I reused the memory from my previous setup, which was a 4x8GB Corsair Vengeance LPX (CMK32GX4M4B3200C16) at 3200MHz. In the Intel configuration, the memory worked stably at 3133MHz, but in the new build it would only run at 3200MHz. I experienced some instability and BSOD issues that transferred to the newer version, so I replaced the memory because it was the only one left to swap. Since Ryzen prefers faster RAM, I opted for a dual 3600MHz kit, but I haven’t reached those speeds yet. I’m using a 2x16GB Corsair Vengeance LPX "Ryzen Tuned" CMK32GX4M2Z3600C18. If I try to set the full 3600MHz, the PC freezes with Q-Code 22 and an amber diagnostic light. When I adjust it back to 3466MHz it boots with QCode 07. The only way it starts is by dialing back to 3200MHz—which would cost £40 if I bought a dedicated 3200 kit. I suspect an issue in the BIOS, so someone could help me fix the RAM speeds correctly. My BIOS settings (with mild overclock): AI Overclock Tuner: Manual Memory Frequency DDR4-3200MHz Core Performance Boost: Disabled CPU Core Ratio: 40.00 CPU Core Voltage: Manual CPU Core Voltage Override: 1.15v DRAM Voltage: 1.35v The rest are fan profile tweaks. If I force the RAM to 1.35V and push past 3200MHz I get QCode 22. Raising it from the stock 1.20V to 1.25V gives QCode 07. It seems the system isn’t happy with any voltage changes. Any advice would be greatly appreciated.
Aaaaah. That old Intel ASUS motherboard had it. The new AM4 board changed the name to "DOCP." A quick search on overclockersclub.com showed that while ASUS introduced the Direct Over Clock Profile (D.O.C.P) for memory profiles, most users still prefer the XMP naming system. It works just fine—enabled and it boots. Thanks! I’ll take you virtual beers.
