I couldn't resist the temptation of the VoltMod

[SolidxSnake]

FINALLY got around to voltmodding my P4P800 (after my computer was confiscated. it's still confiscated btw)!

It was much easier than I thought. I used four4875's guide (which is a sticky, and is found in my thread "Pro volt modders ~ Critique Me!") to small soldering, and got it done within 1 hour (which includes removing the motherboard, warming up the iron, prep work etc.).

And what it will look like when testing VDimm, and my soldering station at the time (I normally solder in my garage on a box, or in my room):

It posts, and it has increased my voltage (it takes a LOT of turns to raise the voltage). I am not sure what the max voltage will be, I'm hoping for somewhere from 3.2v-3.4v. It is currently set to 3.06v.

I haven't extensively tested it yet, however. My computer is not hooked up (Dad got MAD at physically stole the tower from my room, but I found it HAHA). Though at least I didn't break it.

Now, should I get an IC7-G for $40 as-is? Or save my money? Only you guys can answer that question ;)

Hey, clean work, looks good!

You won't be able to get your VDIMM above a fluctuation-free ~3.2V, as VDIMM is fed from the +3.3VDC rail :-/. However, a +3.3VDC rail overvolt will get you higher - a stable VDIMM can usually be run about ~0.1V below the +3.3VDC rail.

[SolidxSnake]

Hmm. I'm not sure if I will/should overvolt my 3.3v. I have the possibility to overvolt, but i'm not sure if I should. Might damage other components on the 3.3v rail.

[felinusz]

A +3.3VDC rail overvolt is completely safe, when adjusted within reason. ~3.6V is safe for day-to-day use in my experience, which will allow you to take your VDIMM to ~3.5V or so. You wouldn't want to run your +3.3VDC above ~3.7V, as it will start to cause SATA problems.

In any case, for your goal of 3.4V it won't take much at all :)


Man, I bet you're dying to get the machine running!

really, I am. Sadly, my dad and I had a large disagreement, but we both feel sorry (and we both know that). I'm hoping I get my rig up soon.

Did 'ya feel the rush right before you pushed the power button after that mod? LOL

I did! There's nothing like moding something that costs 2000 bucks and then pushing the button. it's almost like you are pushing the button on a nuclear weapon! hahaha

It could go nuclear too...that's the rush of it. When it works, it like "YEAH!!!! This *$%*%)*&^%) rules! WOOOO! :)


Hahahha!

It was even worse, because I first thought it was dead. I threw in my CPU, heatsink, and turned on the comp (without RAM), and the monitor didn't get any signal. I was scared ****LESS, so I checked VDimm volts, and saw it was at 2.9v. Acceptable enough. Stuck in my 2 ram sticks, and it booted fine!

WOOO haha

I was scared on the VDroop mod, because there are 2 solder points. One on an SMD resistor, and one on an SMD Point. I was scared because the SMD point was a hard thing to solder to for me, because I had a horrible angle when soldering. I had to redo it many times, and I hoped I didn't ruin the PCB.

Turns out it was fine ;D

When I checked volts in the onboard HW monitor in BIOS (where 3.3v rail reads a few .00v higher, the 12v reads around 2-4 .00v higher, and the 5v rail is dead on), the VCore was dead stable. I forgot to lead a wire from the VCore check to my female molex onboard. Damn =/

Nice work dude. Why did it get confiscated? lol

Hehehehe, it's almost eerie how accurately you described that... I get that exact same feeling every time I make even a slightly risky modification to a piece of hardware and pull it off (And if the dark dieties of overclocking smile with favour upon us, we ALWAYS pull it off... right? :)). It's all about the moment of solemn silence before that power button gets pushed :p

It is such an adrenaline rush... when the hardware still functions after all the crazy stuff you've done to it, you feel like you're on top of the world.

This seems to happen an awful lot (I've kicked a few holes in a few walls, thinking something that wasn't actually dead, was dead) as well...

good job man. now get that damn thing back. or at least go back over to the neighbors and use their comp haha. Now you wont be as nervous with the next one, and it will probably go easier as well.

What kind of iron dud you use? i see a stand and sponge and stuff in the background, just no handle.

[SolidxSnake]

RS 15w iron ;)

[four4875]

boards commony have alot of components left off, to leave off features and cutcosts.

[SolidxSnake]

There are MANY parts that are missing components. I have the base P4P800 rev2, not a P4P800-E or the DLX. ;)

Nice job solid. keep up the good work and keep computer science your hobby/ profession. Just remember- guns and computers don’t mix well.

thats what YOU think
