Man i wish i had known this before i had these hooked up totaly wrong! But my board no matter what i do will not post or boot is it too late? Itried everything but nothing works. Do you have any ideas? And thanks alot for your help.
Sorry man i totally cannot see what is going on in those pics too dark .
PMM,
Can you post a step by step how-to kind of thing and a picture of the completed mod with details of which pins and which chips. Also, maybe a list of parts. I would really like to try this. Will the Ponoma SMD Grabbers work? Thanks
Well, I tried the mod with a 2Mohm resistor. I checked the soldering job over very well, everything looked fine, but when I powered up, I measure the infamous 2.4v reading off the voltage test point. I hope the NB is not toast. I removed the mod to get back to a stock board, but when I powered on again, the measurment was STILL 2.4v, without the mod. So now I have two questions:
1. Could I have burned out the SMD resistor that I was soldering to by too much heat? (The impedence measured about 200Kohm on the SMD)
2. Could someone please give me a voltage reading from the side of the SMD resistor that is supposed to have the resistor soldered on? I checked the other side of the resistor (The side closest to the south bridge) and it measured 2.4v, but the other side (the side the 2Mohm resistor should be soldered to) and I am getting 0 volts. Looks like NO current is getting through the resistor, but I don't know what voltage should be appearing on the other side.
Thanks for any help.
i also was getting 2.4 volts and i smoked the board.
well, i read every post here and your other thread and i almost sure you destroyed your board, veeman. i think it's time for you to pack it up and RMA it asap. make sure to leave no evidence of your v-mod experiments.
damn, my 2nd board does only 188fsb-190fsb max in 3d, no matter what. i know i need VDD mod, but after reading this, i think there's something wrong. i mean 2.4v with 2kOhm pot? can someone clarify this, cos i think i'm missing something here...
Yeah, I am thinking that is what I did as well. Confusing, though. I can't see anything wrong with my work, but 2.4v is now the permenant voltage with AND without the mod in place.Quote:

I had no variable resistors in the mix either. I was using a straight 2Mohm resistor, nothing fancy. I just don't understand how voltage can not return to normal with the mod removed. The good thing is there is no evidense of the mod because I didn't use hot glue. I guess RMA won't be a problem.
Quad just to clarify, use a 1 Mega Ohm resister in series with a 1 mega Ohm pot. Ive done this mod on two seperate a7n8x and both gave me the exact same readout of 1.91 volts max, with pot cranked.
thank you for quick response, Impulse:)
could you please supply some pic, or something. i understand 99% of this, but i just wanna make sure. i bought prometeia and few other things, if i fry this mobo, i'll be out of the game for weeks;(, i'm totally broke and i need to beat my amd/ti4600 competitor;)
can you put your pics back, Impulse? damn, my mobo gives up at 188fsb, just like yours before. i can get it to work at 195fsb, but screen flashes, then turns black and reboots when trying to run 3d. damn, if you don't get the pics up i'll mod it anyway:D
Be careful, Quad. Like I said, I don't know how it happened, but you can kill your board in 2 secs (literally) of soldering to that resistor. Once a mistake is made, it is irreversable.
Have a back-up motherboard ready, should you have to RMA yours.
Nunez - did you go all out with the glue or did you just use a little? Am I correct that you glued the 1Mohm fixed resistor to the point on the mobo? I will try this with my 1Mohm variable today I hope! Please confirm!Quote:

for those that don't have soldering skillz like me :(, I think the best way is just get a resistor and use one end to connect to the point on the mobo and use hot glue to hold it in place nice and easy:toast:
Ya sorry ยงยงยงยง, let me find them. I needed to clear some space on my lame attbi ftp account. If i cant find em I'll snap some new ones.
yes please:) i know where to solder those pots to but i wanna see your arrangement. i was about to do that few hours ago , but i had only fixed resister which i don't like. I did vcore and vmem.
what's your max v-core guys with 25k pot? 2.17v? so far doing 2.65-2.7ghz with no so great AUIGB 42 2400+ at 2.08-2.11v.
thanks for your help.
hi there, just enough to hold the pin in place, the glue won't harm the board and will pull off with enough pressesure, so use as much as possible to secure, while making it look nice without too much:DQuote:

well, something to note is that just because the pot says 2k doen't meant it is, I have tested some 2k and the resistance is many times lower:eek:Quote:

Sorry for not getting to this faster quad. Long day. They should be back up for ya, if you need a dif angle i can try. LMK
alright, sir:) i'll wait. i have one question though. there's one small v-controller next to that small VDD resister, i think it looks like v-mem controller. could someone check whether it's VDD controller? it would be much easier to solder to one of those pins than to friggin small arsed resister.
edit : ok, got'em:) thanks, clear enough
OK, I tried the glue method, and it worked but now it is not! After I did it, i tested with the voltmeter and bam, 1.8V and I was happy! So I put the computer in it's spot, hooked her up and booted at 210 x 11 to test. 1 minute later and freeze... Went to check the voltage again and 1.58V, so I guess the pin lost the connection:mad: The GOOD thing about the glue method is that if you mess up, the glue will come right off, it's not easy to take it off but it is not hard either. I had to redo it several times cause I glued over the spot to check the connection!
UPDATE! I redid the connection with the glue... It is working! I have the VDD set to 1.8V on the nose! Taking it slow, currently running P95 at 210 dual sync and it is passing! Ill keep you updated!
great:banana:
i did the mod too. i used 2.MOhm pot (1.96MOhm actual) and it works. well, it worked. i cranked up the voltage upto 1.9V and now it doesn't boot at all. no sweat though since i think it's becaiuse of condensation around the socket. i took the cpu out of the socket waiting till it dries up.
thanks to everyone involved:)
Hmm, I wouldnt sweat it. I have mine running at 1.91. 3dmark stable at 200, sandra stable at 225
keep us posted. quad do you have any special cooling on the NB? I cant remember
i have some Zalman vga cooler glued to NB. well, it worked fine even on v-modded video boards just fine. I got heatsinks on MOSFETS and Southbridge, Prometeia for cpu. I used some thermal compound from RadioShack on pin holes since i found some water on the socket and cpu.
