Hello guys, i want to undervolt my 13700k .
Short Question :How much should I undervolt? and how can i test my undervolt is stable
-------
mobo:tuf gaming z790 pro lastest update 0x12B Microcode
i see this guide of Buildzoid :
"Testing and Optimizing the 0x129 Microcode on the ASUS Maximus Z790 Apex Encore."

so here is my changes :(in Intel Default Settings(PL1/PL2=253W, 307 A)
IA VR Limit: 1400 for now( maybe 1300 later)
AC/DC Synch = Enabled
CPU LLC = LEVEL 6 (0.49 milliohms)
Tj Max = 85 C
Undervolting : Global Core SVID Voltage = adaptive mode = - 0.09000 (-90mV)
i run a prime95 Small FFTs test for a minute here is my HW info Values :
Vcore (under Load) =1.154
VID(under Load)= 1.162
Max package Temp : 88 C
Vcore max =1.252
VR VCC Current Max = 217.152 A
VID max = 1.270
Max Power Draw = 253W
and i run few loops of CB R23/R24/R20/R15 scores and temp is good (cuz CBR23 draw 220~230W) and no performance lose.(a little question here : my Core Clocks under load in CB23 Multicore go to 4750Mhz. why?! it must be 5300~5400Mhz)
so here is my main question /confusion:
#1 how much can i undervolt ?(Vcore (under Load) =1.154 is it safe/normal???!)
it seems i can undervolt till -110mV without problem but is Vcore (under Load) =1.154 considered as safe (tooo low maybe??)??????
#2 how can i stability test properly?
=== edited====
yes i know i must undervolt till edge of stability and add 5~10 mV to the value
=== edited #2====
I ran the Ycruncher pi 2.5 test. passed
SPs:
SP =88
P core SP = 98
E core SP= 68
