Trying to understand Broadwell-E OC

Recommended Posts

Posted · Original PosterOP

I recently upgraded from an i5 2500k to an i7 6800k.  I have an ASRock X99 Taichi motherboard and a single 4gb stick of 2400mhz Geil 1.2V memory (temporarily until I sell the 2500k stuff and can buy more RAM - and yes it's pretty brutal haha).
I am trying to find something that just explains all the high end desktop features and how they relate to overclocking.  There is much more to X99 than there was to the Z68.  I mean the Z68 was as simple as turning on core enhancement and setting a 44x multiplier and being off to the races.  I have not had too much luck with my searches.  However, I have been able to get my overclock as follows.  core 1.25v, 41x multi, uncore 1.1v, 34x multi, ddr4 stick 1.35v forced timings to the 2400mhz settings and raised clock to 2800mhz.  Machine has been stable for 24 hours now.  My load has been mining Lyra2z with 8 threads while using the system as normal.  The threads are balanced out as 1 thread for core 1 and 5, 2 threads for core 2 4 and 6, 0 threads on core 3 (found it to run hottest so I made it my dedicated free core),   Max temps range 68 to 72 C with this load.  Cooler is a Hyper 212 LED with 2 fans.  Here's some screen snips.

If anyone remembers such a guide that could help me better understand what I'm doing here, it would be greatly appreciated.


There's something cool here - you just can't see it.

There are guides for BW-E on overclock.net and Asus forums, and i believe der8auer has a YouTube video where he walks you through the basics of overclocking a 6950x, the process is the same for any Broadwell-E cpu. 

 

I still don't have mine dialed in but I'm running 24/7 stable 4.5 gHz on my 6900k @ 1.40v with temps never above low 50s.

Mainstream desktop: i9 9900k @ 5.3 gHz, 32GB @ 3200mHz G.Skill Trident-Z CL14 DDR4, Nvidia Titan RTX, Corsair HX1000i, Samsung 960 Pro 1TB, Asus PG279QZ monitor, Asus ROG Claymore keyboard, Speedlink Omnivi Core mouse

I'm not looking as much for an overclocking how-to guide, as I am looking for a breakdown what the things are, what they do, ect so that I can go at it myself with more understanding.  BIOS labels and descriptions aren't that great.

https://edgeup.asus.com/2016/broadwell-e-overclocking-guide/  I believe this is the one you were talking about and it looks like it is exactly what I was looking for.  No idea why this didn't show up the first time I was searching.
