Thank you for your help.
Remember after putting F7 on your USB, before flashing, go into your bios and write down on paper the 2nd and tertiary RAM timings that are shown in F8.
Probably best to write them on paper but if you feel screenshots are better, whatever works (I never used the screenshot feature, maybe i should).
Then after reverting to F7 and setting XMP, save, reboot, and compare the settings. That's why writing them down on paper is easier..you can see what you wrote and compare them easily while saved screenshots would be awkward (I guess unless you used your phone to capture them!). Then its prime test time.
If there is a difference in subtimings between F7 and F8, then it's pretty easy to just change that timing back and see if you regain stability again.
Just to note: It was F8H where I noticed it requiring more voltage. I just never thought about RAM subtimings as I really know little about RAM.
Another user earlier in this thread said F8H was more unstable and 10C hotter than F8G, but 10C is a massive amount, so I really can't believe the accuracy of that.
BTW is your prime test with AVX enabled, FMA3 enabled or with AVX disabled (SSE2/Type1/Core2/Pentiuim4/type 0?)
