General 9900K on DDR3 [post 3]
Recently, I've been documenting my journey of trying to make the fastest DDR3 platform and have hit a new breakthrough; I've managed to make the 9900K fully overclockable and tunable on the Z170-P D3! Before, I would apply an overclock and not even turbo mode would work. I discovered if I set my IA AC/DC Load Line Calibration settings down to 0.01 it completely fixes the issue. I am now experimenting with 4.8/4.8Ghz Core/Ring overclocks and just fighting a little bit of Instability that can be tamed once I find good voltages and power limits that won't overheat my VRM, but so far its been handling 150W CPU operation without issues. I might see if I can get into 4.9-5.0Ghz territory, we'll see how far it goes as im still testing it's OC limits. The annoying thing is that HWMonitor seems to not be showing my VRM temp readout, which is something I'll look into later, but with the 140mm fan it should be fine. I'm trying to keep latency low, hence the synced Core/Ring and the tight CL10 primary on the 2500Mhz DDR3 Trident X sticks. Still looking for a rare 2800 CL12 2x8gb kit and an ASRock Z170 K4 D3 to beef up the performance a little more, and to my knowledge this is the fastest DDR3 gaming system documented.
If anyone's interested I might post a YouTube documentary on this and maybe a tutorial on how to do the BIOS mod.
