when the vid pins are all high (the cpu grounds them depending on the stock voltage), the vcore cuicitry is told to provide 0v. the vcore is on the motherboard though, not adapter.Quote:

i soldered the pot on and set vcca to 2.33v. booted right up to 2.6. i played with it and was able to post at 2.8 :D !!!!!
that's the highest i've ever gone. i'll set vcca to around 2.8v and see where that gets me tomororw.
i love you guys :toast:
and just fyi, the adapter supplies ~1v for vcca when the 1.2kohm resistor is missing.
i was getting confused because i was reading off of the wrong 533fsb jumper, but i've got that figured out now :)

which one do i order ? :/
What mods do you need skirms?Quote:

hum , good question :)
so i think i havent all understood the first thread :o
how many mods on the ct ? Vcca , ..... and haven t seen where to mesure for vcca for exemple
:/
Do the vcca/533 jumper first.......You find the max cpu/fsb bootable on that mod and start adding the ceramic capacitors around the adapter...This way we get a good final results as opposed to doing everything all at once and when something goes whack:D Rather hard to diagnosed.:)Quote:

atm i m on the 400 jumper
but which one is it ?
sorry but i dont understand which mod is for what and i like understand what i do :p
like control the measures
skirms, scroll down on this page and you'll be able to find how to do vcca mod.Quote:

cirthix, never ever fear cracking the core. It's probably whats holding your clocks back:D :D . Just think that your cpu is already dead or you hate is so much that it overclocks like a pos:D . It's what most of us if not all drive us to push it higher or find other ways to do mod to reach higher and have the best time doing so.:D After all this is our hobby.:)

using the 533fsb jumpers
WTF!:D Your one mouthy kid aren't ya!:D :D If you re-read this whole thread you would find yourself asking the same questions over and over again. You call yourself xtreme. Ohh Pleaseeee......xtremespammer maybe:DQuote:

Those measurements look like what i got at stock, adjust away :D.Quote:

and this cpu sucks. even with vcca at 2.7v, it still craps out at 228fsb in clockgen!
vcca done with 5k pot set to 3.2ko
1.52Vcca => 1.841 :)
thx :D
about the others mods i must order the ceramics and electrolytics capacitors
but which one here ?

thx
Edit: Mybad asked a stupid question =P :D

Completed the mods, adapters are posting, and OCing..... have yet to see what these can do, as we just finished the mods (did 3 adapters)
Here are some pictures showing the mods. All parts from DIGIKEY.
These were all hand soldered under a microscope capable of 90X magnification :)
Images are untouched, and not resized as I wanted to show as much detail as possible.

wow
have you checked that electrolytic cap will fit in the socket?
Yes the radial cap fits fine, It does hit the plastic mounting bracket, but who uses that anyway :p: , I use threaded rod up through the 4 holes to hold down my water block (maze 4).
If you wanted to use that plastic bracket, you simply need to file a notch in it at that spot as its only 2mm too thick.
I notice that you've used tantalum electrolytic capacitors for all the cap points, have you confirmed with George (Hipro5) that this application is acceptable? I'm not sure if all the mod caps are OK if their polarised or not but I could be wrong :) Just something to check before you use it
Already Checked all the points with a dmm, and yes the caps are all polarized, The adpaters do work, here is the correct polarization of each spot:

Hope that helps :)
Hi there, my first post here although I've been reading this board for many years !
I'd like to thank hipro5 and all the others for the mods, the VCCA mod is definetliy the killer one ! :toast:
But, as I experienced, take care with this one. 2.9V is already high !
I've done the mod with 2 fixed resistors and a 1K 20-turn pot inline. The value is adjustable from 365 to 1338 Ohm. My thought was not to go over 3,3V but this is already way too much.
While I was testing the overclockability of my CPU I had the mod fully open (3.22V) During benchmarking I noticed a bit of an electric-burning smell. Later I took off the CT-479 to solder on the 12V cap and saw that a block of pins was black, and on the socket of my mainboard the corresponding pins were blackened too (see attached picture).
The pins are :
V3 - V6
W3 - W6
Y3 - Y5
I haven't found a datasheet to see what function they have but I think the burning has to do with the VCCA voltage.
So, be warned :cool:
But the mod is really great. Without it I couldn't go over 230 FSB, now I am running at 9 x 301, perfectly stable and with a VCCA voltage of 2.65V. Luckily I didn't waist my board !
Hope it helps you guys, don't be as stupid as I am and take care with high VCCA voltages !
