7700k OC Stability issues? Manual / offset

[AvengerUK]

Hello everyone!

 

Hoping you can help me with my OC.

 

Firstly - worth mentioning I have a binned 5Ghz 7700k - which I have de-lidded for temps, and using the latest bios.

 

I initially thought my OC was stable @ offset voltage resulting in ~ 1.360 (I can't get 1.350, either 1.344 or 1.360 - I know from the bin that 1.350 is the spot).

 

However, crashed a few times while gaming

 

I am now back to Manual set to 1.350 - LLC 6. Full settings in screenshots below. Prime95 has been stable @ large 1344 FFT for an hour (more to do) - but realbench (specifically, lux mark) crashes. I think that may be an issue with my drivers as its the display that seems to crash (screen goes off for a moment), so I'm focusing on Prime95. (GPU is stable btw elsewhere).

 

Temps under stress are max 67-70

Manual Vcore: 1.35 (Under stress in CPUZ = 1.36)

CPU LLC = 6

CPU Current = 140%

AVX offset: 3

All cores to: 50x

AI Overlcock tuner = Manual

BLK 100

Multicore enhancement = 0

CPU Core/Cache current limit = 255.50

DRAM Volt = 1.35

DRAM speed: 3000

All other CPU volts auto (e.g. SA)

 

Power limits:

 

Long: 4095

Package: 127

Short: 3095

 

DRAM timings are set to manufacturers rec.

Now, if this remains stable - I'm guessing it's good. Note - VCCIO and SA Auto volt quite high though!

 

But, obviously I want to allow the CPU to downclock / downvolt when idle - however offset doesn't want to be stable at these or higher volts!

 

Any pointers? (I'm going to guess your going to say "Use Adaptive" - however I've never managed to get that to work! - usually overvolts massively).

 

Thanks!
