Discovering memory issues means struggling to recall information or retain new data.
Discovering memory issues means struggling to recall information or retain new data.
I’m working on diagnosing a PC built some time ago for a family member. It began showing frequent blue screens. A stress test on Aida64 revealed instability and halted the process. Further checks indicated an issue with the memory. Memtest86 detected numerous errors. After swapping in replacement RAM and rerunning tests, all results were clean. Multiple runs confirmed no problems. I replaced the faulty RAM with original units and repeated testing—each time passing without issues. Now I’m uncertain if the problem lies with the RAM itself or another component like the CPU or motherboard. The parts listed on the motherboard site claim compatibility, so it’s possible the hardware is defective. To confirm, I’d need to try a different motherboard and CPU, though I don’t have spare Z690/LGA1700 parts available. I appreciate any advice you can offer.
When a single system has issues while others function normally, verify twice. Ensure all settings remain consistent; use Memtest86 to confirm stability.
Did you check each faulty stick separately? Did you also test the other two slots? So you received errors without XMP activated? Is your BIOS up to date? Were you inserting the sticks carefully every time (avoiding too much pressure or not enough)? Could you reproduce the issues after switching the RAM? I suggest checking bent CPU pins, but the other RAM worked fine. I use Testmem5 for quick RAM testing. Edited March 11, 2024 by leclod
I evaluated each stick separately. Both trigger errors during the memtest. I examined every slot on the motherboard. All of them produce errors. XMP is turned off. No special BISO configurations were set. Both PCs’ BIOS are current. I believe I placed the sticks properly; they clicked each time and the BIOS recognized the right slots and details (like capacity and frequency). The issues appeared only with these sticks, not with other RAM. The “faulty” one didn’t cause errors when installed on another system—it’s an LGA socket, and the CPU pins look fine. I’ll review Testmem5 next.
