Could someone verify if that is the correct way to trace with a pencil to do the mod?

so correct me here if I am wrong. By tracing acros the transistor, arent we just completely by passing it effectively have no resistance?

I didnt tell that I've killed my P5KC secondly :D
It was a modding and overclocking show here in Hungary 2 weeks ago, and we presentated Dryice and LN2 cooling. It was no problem with the E6550 CPU, I push 630fsb from the KC on DI :)

but with LN2 I've tryd to push up to 5GHz my QX6700. and I've give 1.85v+ vcore, and the mobo crashes.. one ic was burned under the heatsink :D

Any ideas to fix it? :(
OMG! you scare me. I hope that doesn't happen to mine. Especially because I just got the vdroop mod to work. 1.525 set in bios and after a few min in P95 its 1.536 according to cpu-z...wtf?
--pak
sorry :) extreme oc'ing isn't safe, especially with LN2. I've given to more voltage, this mobo has got only 3phase, cant handle so much voltage to a Quadcore CPU :(
but back to your problem, CPUZ didnt correct, its only estimated. if you wont to know the real vcore you need to measure it, with a multimeter where I signed the vcore measure points on the mobo. http://img517.imageshack.us/img517/343/vdrooplb7.jpg
Well I keep my multimeter at work. I'll have to bring it home tommorow to be certain on the vcore. Aslong as the vcore stays in check close enough to what I set it at, I am fine. Before the mod, its seemed like the vcore would continue to drop after a few hours of P95.
I currently have my vcore set to 1.4 and it is staying at 1.4 loaded. It booted at 1.392 then moved up again after a few moments in P95. W/e the case I am satisfied. I currently have my quad at 375x9 which I couldn't achieve even at 1.5625 vcore previously.
Has anyone had any bad side affects because of this vdroop mod so far?
Thanks again!

No way, from only vdroop mod I dont think that ever one mobo died :) But dont forget something, the vdroop mod is like the name, its for dissolve vcore drop under load, but bios set voltage not every case will be the same. Like with my P5K mobo. I do the vdroop mod but still it was 0.01-0.02v difference to bios set and real voltage.
Welcome ;)
Vdroop and vcore mods working great for me still, 0 issues.
Achill3uS if you have a dead board lying around you may be able to replace that IC, my friend has done it successfully.
Cool man, GL! Btw, did you ever get the vdimm or pll mod figured out?
Ah nice, I should be able to figure em out from there. Could you list the coding on those chips though so I know which they are? Thanks!
does this board have bios options to run ram at ddr3 1600mhz?
I can’t wait to try that pencil-mod when I get home from work! I switched my B3 for a G0 yesterday, and tried it at 3.5Ghz with the vCore sat to 1.675v in Bios but it dropped to 1.4 under load. That’s insane! To make things worse, under full load, the multiplier drops to 6 after a minute or two, then it jumps back and forth between 6 and 9. And that is with Speedstep disabled.
Well, it is.
The frequency remains perfectly fine on 3.5Ghz while it's idle, but the multiplier drops after Prime95 has been running for a minute or so. CPU-use is still on 100 % while this is going on, and Prime does not fail.
When the multiplier is at 9, temps are about 68°c and vCore is at 1.400
When the mult drops to 6, temps drop to around 64-65 and vCore jumps to around 1.460
the only thing that I know that would cause a multi to drop to x6 is C1E, is it disabled in bios.
Yes it is. But my last post should explain well enough that it isn’t a matter of Speedstep (C1E). If it was, then the multiplier would drop while the CPU was idle, not the other way around.
Edit: Nice, the pencil-mod worked. Only just trying it out now. On 3Ghz with the vCore sat to 1.4v in Bios, it fell to 1.224 before the mod, now it's 1.312. Not perfect, but much better. With the B3 I had before, it was at 1.208.
Hello boys! Some owner of p5kc, can confirm to me if configuration raid 0 works well? I have not understood well like connecting the hard disk (inner/external), and like setting up them for having one good speed of transfer. You can give to me one hand? Thanks in advance payment for the aid.
@Achill3us
Just registered to thank you!
Did the pencil-mod and Vdroop of 0,06 V (idle to load voltage) is reduced to 0,00 V. Even the difference between bios-setting to load voltage is reduced from 0,09 V to 0,01 V. Now I am able to stable OC my E6750 on teh P5KC to more than 3820 instead of 36XX. Great :up:
Well so much for the P5KC, mine blew up like many others. :(

Have to find that lil chip now to replace.
Yeah this is true, even with vdroop mod it could not hold load and after about an hour of priming poof. What makes me mad about all of these P5K is the vreg is so crap you either get 0.25v less that you set in bios for load or you droop mod and it blows up because the ic cant handle it.
Cant someone make a board that can hold load without droop or fire? :mad:
And thanks, ugpm
Omg :down:
After seeing the last two pictures from Donko, I hope that my watercooling block can handle the heat from the vdroop and a 1,45V Quad Core...
Do I need to worry about anything? What settings did you run?
That was pretty low volts, I just had vdroop mod done so instead of drooping like hell to save the transistor, it blew. I wouldnt worry about it, just put a fan over that area if you can. :)
I have it on water. 22°C - 27°C. Should be enough to survive the 1,5VCore I am currently running for the next 4 1/2 hours. And if not :rofl: :down:
So watercooling is needed for this board+quad+phase? ^^
Hi!
This is not an overclocking issue, but I have read about ethernet problems with this mobo here so that's why i am posting here. Maybe you can help..
I have a new asus p5kc and it has a weird ethernet problem. If I try xdcc-ing on irc (http://en.wikipedia.org/wiki/XDCC), the whole connection dies. I mean not only the internet connection (which is through a router), even the LAN is unreachable until I reboot. After that everything is ok again.
I have tried using a PCI card, and it has no troubles with xdcc (and of course i never had problems with it before the new system). I had an older driver for the integrated one, so i've updated it to the latest to see if that solves the problem but it didn't. I use torrent and ftp and a lot of other protocols but none of them seems to kill the connection like xdcc does. Xdcc uses ports from 1024-5000 so i have tried modifing them to see if the problem has anything to do anything with ports, but the result were the same (after like 15 seconds disconnected). A friend of mine has p5kc as well and has no problems with xdcc-ing so not all of the p5kc-s has this problem.
I can return it, but what if I get the new one and it has the same problem? :) So I wanna try everything to solve it before i go for a new one.
Any idea?
Is the P5K Pro the same with P5K C when it comes to oc-ing quads?Cause I would like to buy one p5k pro and a 8200 and I was thinking that maybe in the feature i would go for a quad
Is there any board with the same price or lower with P5k PRO that is doing well with oc-ing quads?
Or should I try a cheaper mobo and good oc for now with 8200 and when it's time for the quad,get a new and good budget board for the quad(hopping that in the future would born new mobos that would do oc easy quds)
thank you!
Did you go towards 540 FSB? :D
I got 571 fsb on this board.bought the msi now gotta wait for ddr3.this board was a real pos.i do have pictures at that
dont know how to post them here anymore
swore off intel with there socket 423 then went back lol
asus has good stuff if u got the cash or get it free
but im swearing off asus for this board
may last 3 or 4 years lol
first board was doa i see the ddr3 1800 down to 330 at ewise
$100 off ill buy em
till then just keep abusing this pos no wonder they dont bother with a good bios lol
I don't think too it is an o/c pb .
After reading some posts on forums related to this mobo , I definitively point at attansis drivers which looks very buggy .
My ethernet port is recognized under windows but once worked after I plug , then no more .installed drivers several time without success then let it down ! :mad:
Actually using a PCI card and very happy with ( realtek like ) :yepp:
forgot about my attansis gigalan ........
Hi all!
Did anyone figure out, where is the Vdimm measurement point, in this mobo ?
asus should try making a new stable bios, cause 1001 and 1105 are totally failure.
dont try those two
