Hello everyone,
recently i've overclocked my 4820k @4.5ghz using offset mode and i'm using BIOS ver 0701
i have 2 bios settings that stable 14 hours of prime95 and 20 pass of IBT blend 14Gb RAM.
1st
Offset: +0.040 (CPU voltage max 1.248, min 1.232, 1.248 @ 100% load)
CPU Load Line Calibration: High
CPU Current Capability:120%
CPU Power Phase: Optimized
2nd
Offset: +0.075 (CPU voltage max 1.296, min 1.248, 1.264-1.280 @ 100% load)
CPU Load Line Calibration: Medium
CPU Current Capability:130% (OCP Tripped at 120% when stress testing, current inrush inertia didn't help)
CPU Power Phase:Extreme (greyed and cannot be changed without dropping CPU Current Capability to 120%)
my questions are:
1. Why board's OCP tripped when i'm using medium LLC and 120% CPU Current Capability but fully stable when i'm using high LLC? is it normal?
I think medium LLC should have a lower voltage spike that couldn't tripped the OCP
2. Did BIOS 0701 change the CPU Current Capability default level from 140% to 160% when using auto?
i know 140% CPU Current Capability is recommended for overclocked system but i like to lower it down to ease my mind.
ps: sorry for a long post and bad english
😞
