did you just use solder and no wire? looks like thats a piece of solder to me haha. i did try resetting the bios, my computer has been like this for a few days, I am going to test my memory and cpu at a friends house. I just bought a new X800 pro vivo also. I hope my memory and cpu are fine =/. I checked all my voltages with a dmm on my board and they seem fine, vGPU = 1.4(stock), vDimm = 3.5(3.3v->vDimm), vCore = 1.6(1.525 in bios, so that seems about right, looks like the mod was done fine), either my memory or cpu must be fried =/. I really hope it is the CPU since bh-5 is no longer manufactured.
The silver wires are the actually resistor legs, I soldered them directly to the points without any wire as such.
:eek: That is a shame :(Quote:

I had an IC7 before the P4PE which died, I did the vdimm mod on it malves style and it worked great. After about a week the machine just power off and wouldn't boot back again. No fans nothing, the LED on the board was on though and when you pressed the on switch you'll see a flicker of red where it would normally switch colours when booting and then revert back to green. It's just one of the risks you take when solder you board I suppose.
Yep, its always a risk to Vmod anything.Quote:

I think one of the main things alot of people forget is that increased voltage means more heat, which means better coolign is needed.
Now, alot of people think/know to adjust their CPU, Vid Card, and sometimes NB cooling....but give little thought the FETs and Vregs that are now carrying an increased load.
I tested my CPU at a friends house. It did not work at all. SNDS or I don't know what could have happened. The memory was fine, but it only worked in single channel for some reason??? When I tried his CPU and my memory in my board it didn't work. He would not let me try his memory in my board. I don't know how this could have happened. My computer has been down for a long time, ever since my failed x800 mod, and I just wanted to use it earlier this week with an old card, and that was when I noticed my computer acting this way. The computer was working 100% fine before the failed x800 mod. The droop mod should be fine though, the voltage is reading 1.6... I guess I need a new cpu/memory =/. Anyone know why it wont go dual channel??
Del, just got a quick question about the ADP3180 chip u did that mod too.
Could u explain the markings on the chip,
"J 0418"
"444379.1"
Because mine reads ADP3180:
"J 0348"
"345712.1"
As long as the chip reads ADP3180, thats all that matters bud.
The top row of numbers is the manufacture date, and the bottom I believe is the batch number...but not sure.

It would be so much easier if I had a thermal imaging camera. ;)
The guy I bought this board from on ebay has been giving me the runaround. First he says it got returned as undeliverable. Now he's saying if it hasn't arrived by the end of the week he'll just refund my money (less "shipping" and paypal fee's I'm sure). Sounds like he wasn't happy with the closing price.
thanks hell-fire, i thought I'd be safer to ask then to solder and find out I got the wrong chip.
I highly doubt that the p4p800-e deluxe's wouldn't all use the same controller as each other rudski, gl on the mod.
that is an extremely clean mod GREAT WORK!
Once you get down and look at the points, it may look a little challanging, but if you have the -E Deluxe, just solder the pads to the cap (they are connected anyway, and then u have a bigger area to work in! Cheers

Just installed the mod...and it seems to be doing nothing :(.
vcore @ 1.725 in BIOS results in 1.775 in windows at idle, under load it drops to 1.6-1.65v. I've got a 47k ohm VR set @ 28k ohms, just like the OP says, but it's not doing much. as-is, the voltage drop is completely killing stability....
I didnt know they made 47K Ohm VRs.
I take it you are reading Vcore with a DMM and not some windows utility.
I'm assuming the VR is 47k since just about the only identification on the thing is the number "47k" on the side. My fluke is reading its resistance at 28.30k (28300), so it should be set correctly.
Sadly, yes, all I have to go on for the voltages are software monitors. If you could point out where I can read them with the DMM, i'd be glad to see if windows is just being its usuall dense self.

Try checking the Vcore on the FETs around the cpu socket, and the solder pads for the Chokes.
I dont have a pic of a P4P800 around, but here is where I suggested to someone where to check the Vcore on a P4C800. It should get you started in the right direction. I only point out one FET to try and a few Chokes in this pic, but I would check all the FET legs that are nearby the socket.
I did the drop mod and Vdimm on my P4P800-E rev. 1.02.
The Vdimm works great and here are my results on drop mod:
I set the VR trimpot to 28K and when installed i read 20,2K because it's paralell with the snd resistor. I made some tests and the Vcore was much more stable. I set the Bios to 1,5625V and in idle it reads 1,648V.
I ran speedfan 1.45 to see what was happening to the Vcore and it's oscilates a lot less but sometimes it drops a lot. (To 1,584V) but anyway lot less than before. I adjust it to 22,5K (remenber it's in paralell with snd) and the drops was more frequent. I went back to 20,2K. Does anyone here has the sames results???
I was able to reach 3,9Ghz with my 2.8C M0 SL6Z5.
Other thing: Does anyone knows if there's a BIOS to enable PAT on P4P800-E??
Thanks!
I did the droop mod last night with a 27k fixed resistor and a 2k variable resistor in series. When I turn it on the PSU fans spin up, but the board does nothing. No beeps, no cpu voltage, no video signal. I'm gonna clip the wires now and see if it posts...but dangit that wasted a couple hours last night. Anyone have any suggestions?
I measured the pre-mod resistance at the point of soldering to be 73.8k, set it to 29k pre-solder, and the combined resistance was 20.2k, seems like that is what others were getting...maybe I need a higher resistance for my board :(
sounds like you've shorted something or blown a vreg. check your soldering carefully, and HOLY THREAD RESSURECTION BATMAN! :D
Got it fixed. Turns out I burned the trace which goes between the capacitor and the original resistance when soldering to the bare pads. I just had to solder a small wire in to replace the trace and its working good now.
On another note...there is good reason why a 28k resistance is the best value. When looking through the data sheet for the voltage regulator IC, they show three possible configurations, one of which is for most accurate voltage output. Guess what resistance they show in parallel with the 100nF capacitor? ..... A 20k Ohm resistor!!! Why did the mobo manufacturers ever use anything other than this value? I measured mine at 73.8k Ohms, with a 28k Ohm resistor parallel, this comes out to 20.3k Ohms.
Voltage is much more stable now, though there is some droop. I have my 2k variable resistor maxed out right now...series with a 27k fixed resistor I am at 29k total, so I need to lower it some to get the best performance, but I am very happy so far.
see my recent post for the pics by malves of the p4c800 vdimm and droop mods
the proth pencil ghetto mod for the p5wd2 premium can works on p4p800-e dlx?
http://www.xtremesystems.org/forums/...ad.php?t=94659
thank's for the answers
I don't know, did you read the entire proth thread? I know the 28k fixed resistor mod works like a charm. PM me and I will send you the pic.
I know that the 28khom resitor works fine..but i can't solder it on the mobo...because I'm not a master whit the solder :D
if the ghetto mod works...i try it...and go for dry benching on my nw...otherwise i will bench without the vdroop :(
sorry for my bad english...
