Issues with your PC setup.
Issues with your PC setup.
I gathered the following components for your PC build: ASUS TUF GAMING X670E-PLUS, G.Skill Flare X5 DDR5 64GB RAM (2x16), 6000MHz CL36, Ryzen 7 7700X 4.5GHz CPU, and Cooler Be Quiet Dark Rock Pro 4. I used a 135mm PSU from Be Quiet Pure Power, 750W, 12MW. Initially faced challenges with multiple RAM modules until the CPU failed and was replaced via RMA. After swapping in just two modules, I ran a memtest86 and encountered numerous errors. What might be causing this? How can it be resolved? Manufacturer: ASUSTeK COMPUTER INC. Model: TUF GAMING X670E-PLUS Version: Rev 1.xx CPU: AMD Ryzen 7 7700X 8-core, clock 4493MHz (turbo 5490.7MHz). Specs include 16 channels, L1/L2/L3 caches, and 15602M RAM. I installed one module, performed a test from a USB stick, and still faced significant issues. What could be wrong and what steps should I take?
It seems your memory might be faulty or not functioning properly. Check each RAM unit separately to determine if the issue persists.
You should verify each stick and slot separately to ensure they're not among the faulty ones. DDR5 performance in quad setups has been questionable from the beginning. It's best to stick with 2xGB RAM modules only in DDR5 systems. Avoid combining kits, even if they match in brand or model, since compatibility isn't guaranteed by the factory. How is your RAM configuration? Did you buy a single 4x16GB unit, two 2x16GB sets, or four separate 16GB modules? It seems likely you paired two 2x16GB kits to form a quad configuration.
To fix the problem, replace both the motherboard and RAM sticks. Use a 2x32 kit since four sticks aren’t necessary. If you don’t need more than 96GB of RAM, consider a 6000MHz/30GHz kit while you’re at it.
Test a different stick in the same position to confirm it's a slot issue. If there are no errors, the other stick is faulty and should be replaced. If problems persist, switch to another slot—no errors there suggest the original slot is defective and requires an RMA. If you face issues regardless of changes, I have no further solutions.
You checked the mixing process carefully. The pairing should follow sequential serial numbers. Mixing up the kits might cause issues even after removing one, as non-sequential modules can interfere. For testing, I usually verify each slot first—if both modules function without errors, I proceed to test individual slots. If neither module shows problems and all slots display correctly, it likely points to faulty RAM or bad slots. A crash when pairing both sticks usually indicates a compatibility problem between the modules.
