Contrary to popular thought, not all slots are equal on a motherboard. It's basic electronics really, each slot has a different length of circuit traces between it and the respective components it connects to. So while a module might not work correctly in say slot A1 it may work just fine in say slot D1 if slot D1 is closer to the RAM's power circuitry. Longer traces = greater resistance = signal degradation. I hope that makes sense.... That said, the RAM module causing the issue is still either faulty or not quite to spec with regard to voltage. I would test the system thoroughly, power off and on, disconnect from the wall for an hour or so and power on again from a proper cold boot a few times and then, if the RAM consistently shows up correctly in OS begin testing it with Memtest. If everything checks out then you should be good to go. |
Yes, that makes perfect sense. Like wiring an electrical circuit for your home. If you have a long length of wiring, you'll have greater resistance and can have voltage drop unless you use the appropriate guage of wiring. I did't realize something like that would come into play with a MB.
I'll run MEMTEST on the sticks tonight.
Thanks again for all of your help. Much appreciated.
