Bios doesn't accept A or C slots
Bios doesn't accept A or C slots
Your motherboard is set up with BIOS 1203, and the RAM appears to be recognized in a different layout than expected. Check the physical connections and ensure all slots are properly seated. If reseating doesn’t help, try removing and reinserting the RAM modules one by one to identify the faulty one.
Consider swapping out the CPU if needed. Inspect the pins closely for any that seem bent or compressed. What type of processor are you using?
I purchased the used PC and noticed the cooler screws are loose. Have you considered trying other solutions first?
apply 99% IPA to the spray ram slots and let it dry for 1-2 hours. If that fails, remove the CPU and reapply 99% IPA, allowing it to dry. Also, gently apply some to the CPU pins in case they’re dirty. If RAM isn’t detecting at stock settings, it might be due to dirty slots, a dirty CPU socket or pads. At overclocked settings, try lowering the OC value because the RAM might not be sufficient (check RAM limits). If you’re hitting board or IMC limits, it’s normal and there’s no permanent solution—just reconfigure the RAM. Some RAM sticks, like certain Samsung G-Drive models, handle high speeds on outer channels (e.g., 3008C11 max, stable around 2900-2950), but they can still destabilize at lower speeds (e.g., 2800 on inner channels). If only one stick works at the outer channel, consider upgrading to better RAM or adjusting settings accordingly.
