I've been experiencing memory errors when using the default BIOS settings.
My motherboard has two 8-pin CPU power connectors, and I’ve always had both connected. However, after reading that some boards might reduce CPU performance when only one is used, I tried removing one of the 8-pin connectors. Surprisingly, the memory errors stopped.
What could this mean? Is it possible that the second 8-pin connector on the motherboard is defective, or could this be related to power delivery? Are there any BIOS settings I can tweak—like adjusting the TDP or enabling Eco Mode—to test this further?
On the manual the connector is described as CPU_PWR1 and CPU_PWR2. Can I try to power only the CPU_PWR2?
Specs:
I know the Memory is not because I tried another kit, same problem.
