What settings would you recommend? What's the AVX Instruction Core Ratio and Min/Max Cache ratio supposed to be?

Is your memory HCI stable? 3200 is where things can start getting finicky. P95 is sensitive to memory. I would tackle HCI first, then move on to your core overclock (definitely raise that input voltage to 1.9V or so).

The AVX instruction seting will let you downclock when AVX or FMA workloads are applied, you can leave it as is for now.

I'll test the memory tonight. What do you recommend for the Min and Max CPU Cache Ratio?

I agree. Try 1.9 and go again. May have to use more... With the memory and controller drawing more than stock voltage. Or again.... Try with slower memory speeds first.

Start with stock and get other stuff stable first. Unstable cache is very difficult to deal with when trying to get core/memory stable.

There's a few methods on delidding soldered cpus

Some require using a heat gun or ironing tool along with 4 razor blades

Are you still planning on delidding that 6800K? It can still give you 5-6 degrees less vs imperfect solder.

I don't plan on it. Too risky.

Pretty sure CPU cache ratio was the problem. Anything higher than 3.5 and my system is unstable. I ran my system stock for 2 days without issue so I doubt it's the memory. Nothing is final though and will continue testing. So far p95 v26.6 custom test 1344/1344 settings is stable after half an hour using 1.34v

What's the average CPU cache ratio with Broadwell-e @4.4Ghz?

I see people with anything from 3.5 to 3.8 in the BDW-E thread.

I'll have to check out that thread. Thanks folks. Will keep this thread updated with results.

Don't forget he has Load Line Calibration turned up somewhat, which prevents Vdroop during CPU load situations subsequently raising Input Voltage. So during a benchmark his 1.8v input can sometimes raise as high as ~1.85v with a level 6 LLC. Personally i always leave my input voltage on broadwell-e on "AUTO" because it doesn't matter nearly as much as it used to. On Haswell-E if you wanted a 4.4ghz or higher OC on a 5960X you almost HAD to pump your input voltage. But on a 6800K/6900K etc..? Not so much. I'm content to leave my input at AUTO and just raise LLC to level 6 or 7, for everyday use. IF we're talking just all out benchmarking (i.e. short term) then i would actually still go for AUTO but just raise LLC to level 7 or 8.
