XMP Unstable, Please Help
XMP Unstable, Please Help
The system features a total of 32gb of RAM, combining two 8gb modules of G.SKILL TridentZ RGB and two 8gb units of G.SKILL Aegis, all using DDR4 at 3200 MHz. Both sets share identical timing and latency specifications, with CAS latency ranging from 16 to 38. The configuration includes DIMMB2 and DIMMA2 for TridentZ and DIMMB1 and DIMMA1 for Aegis. The motherboard model is MSI x470 Gaming Pro Carbon. The CPU is a Ryzen 5 2600x running at its factory clock speed. Power supply uses a Corsair CX750 750W unit, paired with an AIO Coolermaster cooler. Storage consists of two M.2 NVMe drives each with 500gb capacity. Additional components include a PCIe Wi-Fi card.
When attempting to boot the BIOS into the 3200 XMP profile, stability issues arise—either the system fails to load or becomes unstable. Adjusting the RAM voltage to 1.4 helped, but it didn’t resolve the problem. Increasing the CPU voltage to 1.00 also provided no improvement. Research indicates the Ryzen 5 2600x supports DDR4-2933 with ECC and a maximum of 64 GiB memory, using two controllers and two channels at up to 43.71 GiB/s single and double bandwidth.
Memory configurations include single and double rank options, with various speed tiers available. The CPU has four PCIe lanes and supports up to 64 GiB total memory. There is some uncertainty regarding the exact number of PCB layers for the x470, which could affect compatibility. I consulted online sources, but no definitive confirmation was found. The TridentZ is single-rank, while details about the Aegis remain unclear. Forum discussions suggest that pushing beyond 2933 might be necessary to reach the 3200 MHz target. MSI confirms compatibility of both memory configurations with the x470. It seems there may be a bottleneck somewhere—either in the CPU or the motherboard.
Help is greatly appreciated!
Test 16 gb with Trident, test 32 gb with Aegis and XMP—if it works, your BIOS will configure all RAM to the lowest compatible speed. Mixing different sizes and speeds isn't recommended for stability.
Both RAM sets share the same timing, delay, and capacity. I'll go ahead and try your idea.
There are numerous timing options for RAM beyond the main ones, but only the primary ones are officially advertised. It's likely your motherboard isn't correctly configuring all secondary timings at the desired RAM speed. All secondary timings should align with the main settings. You might need to adjust them manually and test if they meet your needs.
