To answer your inquiry, the motherboard should work fine when populating slots 1 or 3 only. Please confirm the memory part number you are using on your system since "BLS2KIT2GS3D1339DS1S00" is not valid.
The number is BLS2KIT2G3D1339DS1S00
According to the information the memory is fully compatible so the issue could be related to a malfunction of the hardware. Here are our recommendations to narrow the issue:
- Test the system out of the chassis on a minimal configuration. Test each memory slot and modules individually.
- Test with a different power supply with at least 450-550 watts.
- Test the system in dual channel configuration.
If the issue persists, proceed to replace the motherboard under warranty.
I have done all those tests already so I will ask for a replacement board under waranty.
Thanks for your help
