Wont Post From Reboot

[cirro]

for some reason, once go above 1.63v on my mobo it seems to not post after saving settings and restart (yes it saves settings) no error codes anything, but when i turn it off at the power supply with the same exact settings it boots up, (on it right now) any ideas? signature parts specs

 

:edit: oh and this includes restart from OS, but works fine one i manually use my power switch

1.685v?!?!?! Unless I am mistaken isn't that kinda of dangerous even if you are watercooled?

 

Don't set your vCore above 1.63V is a simple solution...

the thing is in the bios, its showing me 1.63 now, and when i get onto windows cpuz,hwmonitor all report a max of like 1.58, its a drop that sucks.

should i try vdroop mod?

Do you have loadline calibration enabled?

should i try vdroop mod?

I assume the 780i vdroop mod is identical to that of the 680i...

 

For me, the mod reduces vDrop and eliminates vDroop

 

vDrop = selected vCore - reported/measured idle voltage

vDroop = load vCore - idle vCore

 

I have 1.5625v selected in BIOS atm,

 

with CPU-Z it reads 1.552v idle and load

 

 

I did the mod live, at 1.4v, with a 4B pencil, then confirmed vDroop = 0 when vCore = 1.5V, then taped it over...

 

 

It's very easy to overdo this mod with a 4B... I tried a HB on another board and it took forever lol... a 2B is probably best

 

Also, don't blame me if you mess up the mod and kill your mobo... but it did help me with speeds > 3.6 GHz that I couldn't get stable sans-mod

yes bios settings finally report the same as cpuid and other programs, yeah, did the pencil vdroop and running at a lower voltage
