P4C800 E Deluxe Vcore mod, Vdrop mod, Vmem mod.

yep it worked, also did the vdroop mod with 28k resistor.

For some reason i can't boot with 1.7v vcore or higer
(don't know if it's because the droop mod)
i read that the vcore fluctuates 0.15v when going higher than 1.7v on p4c800 is this true ? and is there a fix for this ?

all voltages lower than 1.7v are stable

well i work with a variable resistor and over 1,7v you must have more than 28k .. i dunno how much exactly, but never go under 15k

Where can I get a 50K VR? A part number would be a big help.


edit: Found some.

The pictures are down, can anyone fix it pls?

Sorry for use this old thread....

but are the mods the same on P4C800 Deluxe (nonE) ???

performed the vdroop mod yesterday but it was unsuccessful. stock resistance on the vdroop pin was 13.7k ohms. i tuned a 50k resistor to 27k like stated in the first post and soldered it on. checked resistance after and the overall resistance was 9.1k ohms. so my resistance decreased from 13.7k ohms to 9.1k ohms by adding a 27k ohm VR. powered the board on and all i got was a load squeal from the general area that i modded it.

explanations?

This has to be one of the coolest boards I ever used to have. Makes me want to bust back into P4 OC'ing lol

Wow! A five-year thread revival.

Might just have to pull out one of these boards out of the box and give this a go. Recently got a new soldering station that needs to be tested.
