I shall put my celeron M back in with more VCCA and I shall hope to reach >100% overclock which would be my first :cool:
anyway, here's the highest Pi before... :cool:

Bugger. I seem to have killed my 740 with the adaptor :( The CPU now causes the system to immediatly shut down when started, have tried it in my laptop too so it's def the cpu and not the mobo.
For those interested I mamaged to get hold of several of the MOSFETs that the adaptor used (9915H) so if there are those of you out there needed replacements give me a shout. Guess it's time to get a new one and a cpu to put in it :shakes:
I will try this later, just came home from work and I'm little tired. :)Quote:

whoa, guess i was wrong about where to put that cap on the underside! it gave me some problems stability-wise, so i removed it. that solves that mystery.
can someone confirm what is the right solder points for this mod, I always thought it was the first example lukiluke gave....
im told that is correctQuote:

I'll try them to my 780ES too......IF these NEW mods works well as well on it, I think we will have some new WRs......I bet I can do 4200+ MHz benchable.....:D ;)
Hipro: any chance you got a model # or link to that heatsink? Just did a search on "Alfa Pal" found their page but nothing showing that would lead me to a P3 heatsink..Thanks!Quote:

new mods... must have more mods :slobber:
May I say, "veerryy nice" to al those, thinking of these cool mods.
Especially, the Vcca findings (max bootable fsb).
I have a celeron 370 wich does 15*180 stable and 15*184 unstable
and a 760 wich boots at 11*230, but can go into the 280 once in windows
All this with default hipro mods on a Vdroop modded P4C800E-Deluxe.
I would like to know what safe 24/7 Vcca voltages are? Is this the voltage that can be measured on the adapter jumpers?
Hipro, how do you keep your cpu's cool with asus stock cooler and even a p3 cooler? With asus cooler, my cpu's boot at 46C an quickly go into the 58-64C when priming :confused: . I now have a Zalman 7000Cu on it. Now it boots at 38C and gos to 52C when priming. Also when using the zalman, my max overclock increased with approx 100MHz. I'm using Geil-copper-paste.
that p3 cooler is better than the stock heatsink for sureQuote:

you can measure from pin 2, I'm running 2.3v 24/7 fine so far..Quote:

I still haven't done the one I higlighted in red. I read the earlier post correctly you gained 100Mhz-200Mhz from just this mod. I'm at 2.9Ghz atm. My cpu needs a lot of volts at 2.9Ghz just to play games, 1.70V to be exact. 2950 is superpi/pifast/cpumark99 and sometimes if im lucky 3DMark01/Aquamark flaky stable:D
P.S. What were your temps with the Alpha pal hs while you were benching the 770 on air? Maybe I need to calibrate my cooling a bit here for me to boot at 3Ghz:D
Edit:
Here's where I am atm, I could run 2.9Ghz Prime95 for 24/7 at 1.66V Load but crashes in games instantly so I stated 1.7V coz 3D's require more volts to stabilize:)

use OCCT or Systool's stability tests, prime is rubbish IMO..Quote:

JOY!!!!!!!!!
running VCCA at 2.5volts and vcore at ~1.5volts.
try this: http://users.volja.net/jerman55/Burn-In.zip :D :D :D , heats really most !Quote:

Sweet! I wanna try this mod with my 350J (I did the mod for 1.8V VCCA but didn't gain much at all). Did you just go straight for 2.5V VCCA or gradually work your way up to that? (otherwards, do you think say 2.0V VCCA may yield the same result?)Quote:

It is stable?Quote:

I've had to do an XP reinstall and I'm surrently battling with some other quirks the P4GD1 seems to have with celeron M processors, namely supplying vcore voltages ~1.26volts at boot. I will see it I can get it to be stable @ 200MHz over the weekend
Hi all. Yesterday, I removed the 32k mod resistor and solderen a 5k 25 turns pot in parallel with the original resistor, alowing me to control the Vcca voltage.
I must say that the Vcca voltage is linearly responsible for max bootable fsb. (sry for mad english)
2v gave me approx 227fsb
2.5V gave me approx 240fsb
i stopped at 2.8v wich gave me approx 255fsb (haven't tested much since)
Can anyone tell me what would be better for allround performance 2-3-3-5@230 or 2.5-4-4-8@255 ? I have corsair xms3200c2 (TCCD).
My max total cpuclock is still approx 2650mhz @ 1.425V, but have to do some more testing with higher vcore's.
If someone can point me to a place where I can measure the Vcca current, I'll give it a shot.
