HI,
So I set up my 9900K as follows;
BIOS
XMP II = 3600MHz (2x16GB G-skill)
Asus Multicore Enhancement = Auto
CPU sync all cores = 50
SVID Behavior = Best case scenario
All power limits set to max
AVX Offset - 2
Cache Ratio = Auto
IA AC and IA DC = .01
LLC = 5
CPU Core/Cache Voltage = Adaptive Mode
Additional Turbo Mode voltage = 1.290
Offset + Offset Voltage = .01
Dram Volts = 1.35
VCCIO = 1.05v
VCCSA = 1.075
Now this has all been stable under Asus real Bench, Intel Extreme Tuning Utility and Prime95 26.6 custom 12/12 and here is the question???
In HWiNFO64 VID is reading 1.295 and vcore is reading 1.279v idle with windows power plan set to performance....now when I load up Prime 26.6 with custom 12/12 the vcore is reading 1.163v and cpu-z is reading the same 1.163v under load....HOW IS THIS POSSIBLE????? Am I missing something here????? Surely the vcore can't be that low under load.
Also when testing with Prime I initially had VRM heatsink passive and temps hit 75C so I wacked a small fan on the vrm area and temps dropped to 58C so pays when stress testing to have that fan on the VRM.
VRM passive when gaming never go over 45/50C so passive is fine for gaming.
