Unfortunately, it's so sporadic in getting to post I can't even adjust the timings. I barely get lucky enough to have 3200 post at all. Sometimes I'll get 3200 to post and it drops my cpu frequency to stock. oh well.Warning: Spoiler! (Click to show)
The C6H is also a bit "hit'n'miss" for some on 3200MHz for booting.

RB was a tough pill to swallow for me.
I'd never heard of it before getting my 1800x/CH6. After passing multiple stress tests at 4.1, I was ready to back it off just a bit for nice 24/7 OC. Cruised through P95 and RB at 4050 but couldn't pass IBT at max.
Lowered to 4000 and passed everything
, only to learn (from you and the other guys on the CH6 thread) that cursed WHEA Code 19 errors could actually be a problem. Though I couldn't imagine them affecting stability even in the high-stress conditions I subject my rigs to, an unexpected Code 8 two days later proved the error of my ways.
Now I'm at 3950, a full 250MhZ less than what I can boot into Win10 at, but I'm "WHEA free" and can do these all day long.Warning: Spoiler! (Click to show)
Ever consider dialing back a bit to see where you can
pass IBT at max? It might be a more conservative OC, but it'll also be nigh unbreakable...
RB was easy for my CPU, this post
has some of my initial OC testing and is in chronological order.
IBT AVX from Vishera owners thread OP on both my R7 1700 passes Very High, but not maximum.
Here is my 2nd CPU passing IBT on Very High.Warning: Spoiler! (Click to show)
IBT MaximumWarning: Spoiler! (Click to show)
Next same settings x264 as IBT Very High.Warning: Spoiler! (Click to show)
At the mo I'm happy with my 1st CPU regardless of IBT Maximum failing.
Total stability testing for 3.8GHz @ ~1.35V 2400MHz C14 has been a lotta hours.
