I think the weakest part of the system is the IMC and a small LINX run doesnt show ups the IMC weaknesses that well.
Blend does stress the IMC and with the small Linx run stressing the CPU - shows those weaknesses very quickly.
The other way to test for stability, is to run a larger Linx problem, 17000 minimum. Most of the failures on Linx are ebtween cycles of calculations (watch in task manager), you can see it isnt temp that killing the system, its the reading and writing matrix data from memory for the next calculation run.

Those large linx calcs really hurt and my overclocks using that as a bench for stability are way less than any other solution - it depends what you want at the end of the day.....high numbers or stability.

Ps I can complete a 500 cycle run of Linx 10000 problem size which wont complete 2 runs at 17000...its that much of a delta for me.

Would love to see temps of a 20 run of Linx @ 17000 - if our system can handle it.
Vikingboy, you are messing up your vCore testing by simultaneously running Prime with LinX or something else to stress the CPU as Loser777 said. I know it takes forever but you really should use only LinX or OCCT to find vCore and then use Prime blend to make sure you have enough VTT/vDIMM/relaxed enough timings.

Yea I noticed that about LinX. You will fool yourself if you use a low problem size. I don't know why LinX needs to use as much RAM as possible relative to the total to load the system properly but it does. It's confusing because we know that LinX itself does not stress the memory system as much as Prime blend.

I agree though, you need Prime blend to test IMC quality which is also a goal of this thread (I hope).
