What is the maximum negative offset of each individual core before instability occurs using the Motherboard BIOS? If you're properly tuned you should know each cores negative offset value before instability occurs. If you don't, you haven't done it properly.
All core offsets are far from ideal as one or two bad ones can affect things so you have to tune them one at a time.
I can list out each core for my sample and the maximum negative offset it can accept before it produces a WHEA error and a system restart.
I spent time testing each core one at a time, mainly involved leaving the PC on overnight and general day light usage like web browsing. I'd also run a 1/2 hour or so of Prime/OCCT per core to ensure stability under load. Generally though, I had my problems with idle and light load, not heavy load. After 2 days of stability in Idle/light load, on to the next core.
The method in this madness is that if you get any instability, it can only point to one core. Once you get that one stable, whether it is at a negative offset of 0, 5, 10 etc, you move onto the next.
Now I have my 5950X tuned efficiently, and it beats out all other 5950X on OcuK in ST and MT workloads. Here's the kicker, my best core will only accept a -5 negative offset. -6 causes a random reboot of the system, yet this particular core scores 1715 on CBR23.
