Well guys i didnt want to say this but i must tell the truth about what went wrong and why this happened.. In another Thread (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=16688) i talked about my problems with my computer not doing DC and high FSB anymore after somehting went wrong with the MB..

Well truth be told i didnt do the VDD mod correctly at all.. Prob was that i was looking at a pic of the VDD mod off on another computer on the other side of the room.. So when i got back to my rig i thought i lined it up right but NOT!.. I guess it would of helped to turn the pic in the same direction as my board.. I did so after i figured it out though but the damage was already done and i didnt even know it till later on the following day..

Heres where i soldered the 4.75v resistor to..Check the blue arrow... green is where it should of been.. :( I got the pic online somewheres..

Heres pics of the damage...

Heres the back of the CPU socket..

Heres the back of the NB.. http://www.westcoastpcs.com/KnownKiller/dissaster/Northbridge.jpg

Heres a shot of some resistor near the bottom of the board i think.. http://www.westcoastpcs.com/KnownKiller/dissaster/DSC00639a.jpg

When i noticed this was wrong i freaked out.. but at the same time thought i got away with it since i didnt notice anything wierd at the time.. hell this was like this for hours... I then did it right the second time and it wasnt till around then that i noticed somehting wasnt right.. I didnt discover the damage till late last night when i finally took the MB out after i successfully backed up my 40 gig raid off to the backup computer via the firewire connect.. THank god the drives were still good and everything seemed ok.

The only probs i experianced after all was siad and done was the fact that i couldnt run stable at anything other then 166FSB.. Hell i even still managed to run the CPU (2100+ TBred B) at 2500Mhz at 2.06v stable.. At any FSB other then 166 it wasnt stable.. I even tried runing the CPU at 1600Mhz or lower while i tried 180-220FSB and it would either not post or lock durring post or lockup right away in memtest86.. I tried with 3 different sticks of ram that i knew could handle the high FSB..

I found no signs of damage on anything other then the MB.. I just hope my Antec 550WATT PS is still working fine.. though i didnt notice a change in my voltages on hardware doctor.

So let this teach ya a lessen like it has to me.. TAKE YOUR TIME and DOUBLE CHECK, TRIPPLE CHECK THOSE CONNECTIONS when ya mod your computer.


:(

Now i gota run out to buy a new NF7-S v2.0 today.. I hope they still have one left.

Ooops.

Is the only damge to those SMTs that look like they were overvolted?

Is the vreg burnt up as well?

At least you will double check next time :)

This is one reason why people should read and understand the PDF's for the mods there doing rather than just copy a pic.
If you had understood what pins where which you probably wouldnt have messed up :P

I doubt you have hurt anything else..

Is the vreg burnt up as well? Umm whats that??

I've done the mod before about 6 months ago and didnt have a prob then.. Its jus tthe the pic i used to verify what pin didnt have a clear enough pic and i couldnt fine another one on here... I couldnt see the little notch in the chip..

If i had a digital mult at the time i did that, i'm sure i would of noticed before the damage was done...

Though that board was rock stable in every other aspect then high DC FSB i couldnt stand it for that reaosn.. hell i wanted to take the thing out and stomp it anyways it was drivin me soo nuts..

I hope your right and everything else is fine.. Will know in a little while.. Just got back with a new board but i gota eat before i can though it in..

Erm... I did something similar yesterday but it was quite dark and I DID NOT doublecheck cause I was soooo sure :D done it on about 12 nf7 boards up to today. I took pin 5, the one east to the real pin.

And today it died after redoing it :( But no marks on the backside :)

:idea: What about founding a ***club of the dumb vdd-modders***?

Also could write a book about what can go wrong vdd - modding.

Or merchandising articles like dead vdd chips pierced through any part of women (and men - no sexism) one can imagine... :rolleyes:

Oh. Did I think loudly... I dreamt. Do not pay attention. :D

Nice names. I see we've got the same thoughts.

I think we can tell our grandchildren (don't know if the word 's right for child of our child) of doing the vdd wrong. They will laugh their a**es off or would ask V... what :confused:

Mother: Doctor doctor, my son has a problem.. He's been spending way too much time on the computer reading on forums and getting strange ideas of using a hot iron on it and destroying everything!!!

Doctor: I see...hmmmmmm...


Mother: huh? Do you think he needs glasses maybe since all the reading could be harming his eyes??

Doctor: Nope...

Mother: huh? Well what could it be then??? Is he sick? Does he need to be put away?!?!?!

Doctor:... you better sit down miss.. Ya see what i think he has is a rare rare case... What i think little johnny has is V.D.D.

Mother: Oh my that sounds very very bad! what is it?? What do i do? Is there a pill he can take?

Doctor: What?? Very digital dumb?? Noo.. no.... He's fine.. Hes very bright and aware... His heart is in the right place... But the execution is a tad weeeeeee oFF!!!! Get another job, he needs lots of money to buy more computer hardware... :)

Mother: ............

Caller: yes Doctor KK i sent in my computer a week ago and i'm just wondering how much longer is it gona be till i can get off...ummm i mean get the computer back?? :slobber:

Me: well ya know what... i notcied that your computer seems way slow and your expensive vid card is the bottleneck.. and with the proper eXecution i could tweak it.. Oh and your motherboard.. heh i can take care of that 2.. Ever hear of a VDD mod??? hmmmm?

Caller: hey that sounds good if ya could.... "What" VDD???? VDD?? KK??? nooo.. .umm i mean ya know i could fix that myslef.. Is the computer ready??

Me: Look dude! This is how its going down.. I got the iron on and its red hot.. I'm lookin at the VDD mod right now on the screen and ah.. heh.. how much money do you have??

I'm screwed! I knew it! I should of known better.. I didnt listen to my instinks.. The freakin P/S is bad now.. It must be cause the new board is doing the same thing as the last one!

I installed the new board tonight and was testing everything out.. Thankfully my raid array was still usable and windows worked like it didnt notcie anything changed.. I ran the damn board for like only 20 mins... Not striaght though cause i was making changes in the bios and runing memtest86 to test the FSB at 166,200,210 and 220.. then tested the DC at 220 and 210.. Just testing the crap out to make sure that the ram and cpu and everything was still fine.. 225 wouldnt boot or post period.. The board came with the dreaded 16 bios..

So anyways.. i notcied it still acting strange like it wouldnt reboot and just hang at the shutting down screen.. I thought.. hey it could just be the that i installed the windows on the other board when it was already damaged.. lets not freakin out.. or i'm just pushing it too hard with a crappy bios.. I shut the system down when the wife came home and we went out..

I planed later on to take the board out and check the back to make sure that it wasnt happening again... Meaning the P/S could of been effected and melt another board.. And sure enough.. wouldn't ya know it! Its already starting to burn up the same crap behind every chip... the cpu,NB,SB and the dang sata chip.

I should of known better... I've been through this before years ago and when somehting goes wrong with a volt mod the P/S will be damaged and will just continue to eat away the new gear till ya replace it..

So now.. I gota go out and buy a new P/S.. :( Damn beautifull Antec 550Watt has to be tossed! !!@&%&!%# man another 150 down the drain!

I cant take it anymore.. My wife is fliping out and what she always says.. Its a money pit! and the classic... everytime you touch it its a chain reaction! One thing after another goes and more and more money thrown at it..

Damnit man.. I'm about to never touch or tweak again!

Crap.. i gota go return the board as well... They dont even have another one to replace it.. :(

Yeah long ago on the last motherboard... I didnt touch this one. But if you rtalking about when i origonally did the first mod... no.. I didnt have a meter then.. I read that a 5k resistor would of been fine and it was when i put it on the right pin.

Erm. NO. I think my sweet lil antec 412xf has gone through all well and crap boards without a hickup :D
I don't really believe in your theory with psus after vmodding :rolleyes:

But you can try measuring voltages on psu rails under load and on the mosfets laying west to the cpu. Take the middle "leg" :D and any ground. That's for 12V I think. For 3,3V I think it has to be the ram mosfet (correct me if I am wrong)...

Don't throw away your antec :eek:

I always check my vdd. It's been at 1,78V as stock is. So I instantly noticed the mod not being functionable. But it was late and I decided to do it next day... That's what happened :rolleyes:

OMG!!! You just destroyed 2 NF7 boards and an Antec PSU all because you never used a multimeter.

Damn, these things will only set you back some 15 bucks, now you got screwed for some 20 times that amount of money.

I have some understanding for the lady, i still wonder how my girlfriend keeps up with this have-to-have-the-latest-hardware sickness of mine.

Maybe you should get her some flowers before buying a new PSU. ;)

Seriously, it's real crappy to find out your Vdd mod went wrong after a couple 'a months.

Good luck with your new hardware and remember: If it ain't broke...oh well...MOD IT! :)

08-06-2003, 11:25 AM
I'm not about to insall the MB again to test the P/S.. All i did was jump the P/S's Power on and Power ok and i was in business.

Testing the +12v line on a molet connector showed the the +12 flucuates all over the place.. from 12.0-11.40 Never holding still.. The +5 (red/ground) shows that the 5 line is also just as crazy.. I checked the 12V connector line... same thing.. Then i pulled the M/B manual out and tested the lines on the ATX connector.. The only line that was a stable reading was the +3.3 that ran stable at 3.5-3.2v

Ofcourse the P/S is messed up now.. Nothing else supplies power to the board and something was left around from the last board to say "we gona fry this one 2".

I've been honest so far...

Plus the part i was talking about that i should of known that something was wrong with the P/S was before i took the M/B out the one i did the mod in the pics.. I noticed that my voltage lines were different in hardware doc. well everything but the +12v line.. that line never did dip past 11.98 and now it was flucuating from 11.98-11.91 on and off with no load on the system. I dont think i remember seeing anything dramaticly wrong with the +5v line. So that hinted to me that something was wrong with the P/S but i thought it was just the damaged M/B... but when i noticed the same voltage in Hardware doctor on the new board and when i took the board out for a check up i said sheeet! I knew it.

Dude i think you need to chill and read before you post.. you know nothing.

ofcourse i didnt mod the new board.. I did the VDD mod to the last board twice cause i noticed that i did it wrong the first time after a few hours of completing it... but i didnt do it again till the following day when i got me a digital multimeter.

It would be nice if someone could tell me what that leg does that i used... I was just hoping it was a ground.. but i guess not.

Zeus
08-06-2003, 11:52 AM
Never meant to upset you.

I know you didn't mod the second board, what i meant was that if you had used a multimeter with the mod on the first board you would have never killed your PSU and next board, that's all.

No flames intended here, hope you understand. :)

Measure between the leg u used and ground (screwhole or something) if it reads 0 ohm it is ground.

SAE
08-06-2003, 01:24 PM
Hey eclypse :)

Don't think your board is damaged. But of course I cannot see and judge it ;)

But your psu seems to have gotten a hit. But I doubt it was the mod. Maybe there was a bad component cause stable rails are what oc needs and it could be the fluctuation that heated up the mosfets and other voltage related parts like vregs (voltage regulators) cause the board cannot buffer such a range of nearly 10% :eek:

I would try another psu first and then, later, change the board again if necessary.

eclypse
08-06-2003, 06:25 PM
Well i dont know if i wana try it.. I just got a new P/S today.. Thank god for Comp USA.. i picked up the best.. the bigger brother to the one i had.. I had the Antec True Power 550WATT.. Now i got the True control 550.. :) Looking forward to be able to tweak the lines.. THough i didnt need to do it with the last board.. THey were all perfect unlike that new one i had.

They let me return the board where i got it since it was bad.. heh THey even tested it out.. THey only had one more and since it was opened i had them test that one as well and they fond that one was dead.. So since there wasnt a board for me they gave me a full refund.. I'm going to have to buy a new board online..

But what you say is tempting.. but eh.. the damage to the board as it is...maybe ya need to check out those pics again.. Oh yeah it wouldnt over clock anymore after that.. well the FSB wouldnt do over 166.. On the new board it would do 220.. while it lasted..

I'll think about it.. but i believe its a goner..

Sorry about that.. makes sense... i've been on edge lately with all thats happened..

I do believe that it is ground cause i remember checking the connection with an analog multimeter after i make the connect and it showed 0.. But if thats the case then what made everything go crazy, unless the P/S was just going and it picked a good time to take a crap..

Zeus
08-07-2003, 02:34 AM
No hard feelings. :)

If it really was ground there shouldn't be any damage since you connected that leg to ground with a resistor while it was already grounded.

It might have just been your PSU.
Congrats on your new true control, it's one of the best, if not the best PSU's around.

08-07-2003, 12:22 PM
I think i've made a discovery.. Theres something wrong with these Antec True Power supplies.

I'll go back and document the exact voltages on paper and report back but for now i'll tell ya what i've found.. You tell me if it makes any sense..

Well after ordering a new board from newegg last night i was still pondering what Sae was saying about my board.. that it might be still good.. So this morning i started testing everything on it with a multimeter.. testing the ohms to see if all these cooked chips were still good.. and it looks like they still are... i dont know if any traces are bad though.. So anyways the fact that that antec 550 watt TP PS had those crazy flucuating voltage lines was still bothering me.. So i was thinking lets test the new P/S (Antec True Control 550WATT) and see if there any different..

Well after taking it out of the box and jump starting it i started testing the lines to come find out that there the same... well the only really bad line is the 12V line thats all over the place from 11.5-12.17 i think.. The +5v line stayed in the in 5v area and the only thing that stayed close was the +3.3 line that held around 3.30 something to 3.41 max..

SO i was thinking heh who knows maybe it just needs a freakin pull on the line and something will kick in to make this thing stable.. so i slap on my new 120MM fan.. No difference in the voltages.. the 12v is the same.. but i noticed something that alearted me.. THe damn noise from the fan.. It was pulsating... i set the thing down on the table and it was shakin all over the place like someone was turning a light switch on and off..hmmm.. Must be that the voltage is runing all over the place.. Next thing i did was test out the pots they have on that drive bay thingy..

I maxed every line to find that it only went up a little and did nothing to stablize the voltages.. ofcourse it wouldnt hehe. But anyways.. i was kind of dissapointed in the adjustment for the +3.3 line.. It only went as high as 3.41.. :( Which leads me to the other part of my findings..

I have a super cheap 300 WATT ATX P/S that i never used that came with a cheap 20 dollar case.. 2 of them to be exact.. So i said lets test them to see if there lines are all over the place..

So with this one all the lines stayed still on the digital multimeter.. I'm saying they didnt budge one bit! Plus the +3.3 line was solid at 3.42v, the 12v was at 12.17 and the 5v was at 5.07 i think.. I'll retest and verify it..

So anyways i put the same damn 120MM fan on that P/S and guess what... no pulsating noise period.. just a nice solid tone.. Set it down on the table and guess what? Its still, not bouncing all over the freakin place like it was on the Antec True control 550Watt..

So this is telling me that, that damn Antec 550Watt True Power i have that i thought was bad because of a "VDD mod gone wrong" is infact a defective god damn P/S.. probably from the getgo.. Just liek this brand spanking new Antec TC 550.. Becuase infact that pin i used was only a ground... i checked again to make sure ;)

One other thing.. Just to throw in another P/S.. I also tested my older Antec 400Watt P/S... i think the model was the 412 or something.. Anyways.. its being used in this spare computer i'm writting to you on right now.. I just tested it and guess what??? Solid voltages on the +5 and +12 lines.. i tested it from a molex connector. I even raised the +12 and +3.3 pots on it long ago and there solid freakin readings.. no movement what so ever..

So what do you think??? Is these Antec True power P/S no good? Or did i just get lucky and have 2 bad P/S's???

As you can see from my sig I also use this antec 412px psu and I am quite satisfied with it. Got 12,4V, 5,24, 3,48V steadily. And I don't think a 550W psu can better my oc :rolleyes:

heh yeah know... i've been thinking.. I may just swap the Antec 400 Watt out of the spare computer and toss it in the main one.. Throw the PowMax 350 watt in the spare and see what happens.. Though i may still exchange the 550.. heh somehting more to think about.. :rolleyes:

Try it out :D

P.S. The pots inside the antec are of great use ;)
Tweak 3.3V to the max for fsb/Dram voltage stabilizing and tweak 5/12V to around 5,2V/12,4V :)

08-07-2003, 06:05 PM
Already done that long ago.. BUt i just realized something... The reason i replaced that P/S was cause i wanted to have the 12v connector that the NF7-S uses.. I doubt it makes much difference though...

Hmm. You don't have that connector :confused:

Seems to be an older version. I have all tha connectors you need. Psu 's named PP-412XF 400W. But I know from my old crappy Enermax that if tha 12V line in general is bad the conn doesn't help any cause the line is tha same ;)

Well heres an update.. Finally some good news to talk about..

Just gona paste my post from the other thread about the Antec TP 550..

Well what a know! Thanks Mickey!

To test the Antec True Power P/S ya must put a nice size load on it and then it will kick in and stablize the rails.. I just got done testing the old True Power 550 that i thought was bad with the bad motherboard.. since i didnt want to chance F'n up my new board just encase the P/S was bad and bamb! I ran memtest86 and while it was buzy i slapped the Digital multimeter on a molex and presto! 12.7v dead stable and 5.04 stable.. no movement period.

FINALLY!!! Some good news and i can finally rest on this damn P/S bullcrap!

Now i dont know if i should keep this old Antec TP 550 or not.. The old motherboard that was frying is definitly going out.. I cant even run test 5 in mem test at any FSB.. prob is the damn NB though since i did a bad lap job on her and the center dont touch much at all... THat plus after testing the VDD voltage its only giving the chipset 1.65v at a setting of 1.7v in the bios..


Man i would love to save a 137 bucks and keep the old P/S but after that thing was cooking the back of a different non modded new Abit NF7-S i'm not totally convinced that its totally ok..
