OK these are the settings I use to achieve 4.7 stable.
I am new to OC'ing and would like to push this further.
My idle temps are 30-31.
My prime95 blend temps are 55-58.
When I try for 4.8 and above the PC locks up. I have tried increasing voltage to CPU but I think it probably needs other settings tweaked which is where you lovely folks come in.
I know that "cool n quiet" is enabled but i disable that when trying a new OC. I enable it when I have a stable OC to save power.
1.4 vcore @ 4.7 is quite good. You might be able to shave off a little bit of vcore staying at 4.7, but not much. 4.8+ is probably going to require large vcore increases, but I'm intrigued to see what you come up with.
Looks like that was my mistake, I thought the RAM setting was in the AI overlock tuner. You have the RAM profile set how it should be already going by your screenshots.
The jump in voltage needed on my 8350 to get higher than 4.7 was quite a bit. I needed to go from 1.415 to 1.51 to hit 4.98 stable. A solid 5.0 required a bit extra...I think it was 1.525 volts. I had CPU/NB set to 2400 with a voltage of 1.25 (Board was Sabertooth 990fx gen1). I can't remember what HT was set to...I want to say 2600 but I am not sure. I will have to look to see if I have the settings saved or written down anywhere when I get home.
Hi! Here are the settings I used to get to 5 ghz on air with a Sabertooth. Also, here is a pic of my air flow. Note that there are 4 good case fans and no exhaust fans in that lightly modded case.
I can get a stable 4.9 and 5.0 with 1.5vcore.
The temps idle are 42 to 43. But when I use ibt or prime it shoots up straight away.
I have an exhaust fan right next to the d15 exhaust.
Is this counter productive?
the cpu will be on 42 degrees and then when i run prime or ibt within 5-10 seconds it wil reach 62+ and rising. I have to stop the test because of the 62 degrees threshold.

IMO I think the temp increases are normal. I experienced similar behavior when I approached 1.5 vcore on my rig. I don't have a D14, but my Zalman is similar in performance and design. Your ambient temps must also be on the warmer side, I presume?
Most D-14 will let you oc a FX 8 core around 4.7ghz, so you are hitting the thermal limits of the cooler. I had 2 D-14.
I oc a FX-8150 and 2 FX-8320. All three max out around 4.6-4.7ghz do it the thermal limits of the cooler.
I know ppl have oc higher on air.

The front fans look to be positioned well. The D14 fans push 80-90 cfm and unless your exhaust fan pulls at least that much it is a restriction. This causes the hot air from the cooler to recirculate around inside the case and get sucked back into the cooler, which makes it run that much hotter.
The GPUs also put out a lot of hot air, so the intake fans need to be powerful enough to feed the D14 plus push the hot air from the GPUs out the back of the case.
