I recently upgraded my CPU from an i5 6600k to an i7 6700k, at the time of my upgrade my RAM was in Dual channel configuration (DIMMs 2 and 4 as recommended in the manual). The motherboard is a MSI Tomahawk Z170A, when I went to boot the PC back up it wouldn't post and was showing an error LED for DRAM. After trying several configurations I realised the PC would only post if there was a stick occupying either DIMMs 1 and 3, as a result I can run it in Dual channel configuration using the opposite channel to the one recommended to be used first.
When I tried booting in a single channel configuration it would post and detect the ram in the slots but it won't post in dual channel for DIMMs 2 and 4. The PC works fine with other channel except for the fact that I have encountered instability using the XMP profile (which i'm assuming is why they tell you to use channel A first). I have tried updating the BIOS with no impact, I would like to us the other channel simply because it means I am forced to keep my RAM at 2133mhz as opposed to 2400mhz.
Apologies if this isn't very clear and please let me know if you need further details or anything clarified. Any advise or suggestions as to what is causing this an potential solutions will be much appreciated.
Thanks
