Regardless of XMP or not, the memory will only run in Gear 2.   There is no way to change it......
I just upgraded my RAM to 4x16GB DDR4 3600 (Team T-FORCE VULCAN Z). XMP seems to be working but benchmark result does not seem right. Looking it up here shows that on R12 we are stuck at gear 2 mode, and I think it's what's happening on my computer as memory controller freq is 1/4 of the reported ram speed. Here's the confusing part as someone said it will work in gear 1 mode up to 3200MHz, someone said it depends on the CPU and gear 1 works up to 2933mhz and someone said it will only work in gear 1 if XMP is disabled. Can anyone with stock 3200Mhz or 3400Mhz configuration confirm if your RAM is working in gear 1 or gear 2? If gear 1 works up to 3200Mhz I'll just return these RAM and get 3200MHz sticks instead. Thanks in advance.  [IMAGE]
