Asus Maximus III Gene + P7P55D prem VDROOP MOD

[Vivi]

Hi!

These 2 boards CAN be very good if they just didnt have this dreaded vdroop. BOTH boards drop .1 volts in CPU-Z and on my Voltmeter. from 1.400 to 1.305v when loading, thats ALLOT. impossible to sustain crucial frequencies when overclocked with such a droop. Anyway, here's some IC's i thought looked important ^_^.

I'm also trying to learn how data sheets work so if you post what i should do please tell me how you read the datasheet so i can try it myself next time ^_^.

Maximus iii gene.

AARG and while we're at it... could you please direct me to my Rampage Extreme's (X48) Vdroop mod, this board has a HORRBILE drop (the one i have, not every rampage).

you guys rock. Thanks for teaching me!

i will take any pic's , measure any points. just ask!

I dont think the EPU units are responsible for Droop bro, they are inactive until software is installed on the OS (and like hell we ever use it! :p:) the primary driver for the PWM will be responsible. I think some of the pics you posted up are on the money, i'll scout the datasheets hen I have a minute


Sounds really simple but finding datasheets is easy... google the IC code into Google... add "datasheet" to the search phrease if you're feeling pessimistic :p: I've never really got deep with CPU controllers so iv never derived my own vDroop mod :S

Sweet i'll go get the data sheets and post them up!

yea EPU is dodge, thought it was a long shot haha

[CryptiK]

Damn forgot about this sorry. Yeah as above, need the pics of the voltage regulator IC's to see what mods are possible. A couple look promising but the EPU's arent the ones we need as k404 said. I have very little spare time atm but I can have a look when the pics are up.

Any reason why you can't use the loadline calibration features in the BIOS? I know with the Rampage Extreme this can cause dead boards at high vcore but what about the other ones?

Hi!

Yes i felt like a total OC noob.

Since i am a 775 clocker, i always thought the loadline function was dangeorus and useless.

P7P55D premium, 1.475 in bios = 1.45 real = 1.35 load.
P7P55D premium 1.475 in bios = 1.475 real = 1.475 load Load Line enabled!!

so yea, load line fixes my problems... sorry for bugging.

Guys, I have a Rampage III Gene and am looking for a mod also to fix the horrid drop/droop these have, has anyone seen a fix for this?

:up:

[Hondacity]

how do you check the vdroop?

[aussie-revhead]

vdroop is how much actual vcore you loose when load kicks in, my gene is like this -

set to 1.425 in bios
cpuz shows 1.4125 in windows at idle
cpuz shows 1.350 in windows while priming

The harder you push the bigger the difference becomes, I need over 1.6v in bios to get 1.45v loaded.

Doesnt matter now i sold it and bought an E760.
