Any sign of thermal paste, solder or wire fragments on the burnt chip? If not it may have just been a bad chip, for modding purposes anyway.

No, the chip that burned out had not been modded, it was the one next to the voltage regulator of the chipset. Will post pics tonight if JMke can bring his digicam.
How did you secure the mod grounding wire to the fan connector ground? Solder?Quote:

Yeah, That's what I meant. Just looking for any good reason for this adjacent chip to blow?Quote:

Yes, it was firmly soldered onto it.Quote:

@nico:
My best guess is sudden change of voltage. It jumped from 1.8x to 2.04 to 1.94 within 2 seconds. I was usign a 10k pot, so the slightest turn made a big difference. Maybe i should have let it stabilize at 2.04v, instead of turning it back all of the sudden.
With some luck, i'm able to post some pics in an hour.
Could be!, It's best to keep a fine resolution and use to pot in the middle of its range. So 1k is ideal, but 2k would be about the max you would really want to use.
A friend, Jmke, took some pictures of the burned out chip and has put 'm online:

Notice the white spot on the chip. That's the area that glows when I try to power the mobo.
Damm! you couldn't get much of a heatsink in there. :( maybe a long flatish one across both chips?
Like Nico mentioned, you using a 10K pot probably did in your m/b. When you are shooting to use only 600-800 ohms with a 10K pot, which doesn't have a large turning radius, put you literally at the end of the turning radius. Now, slight movements mean big jumps either up or down......Quote:

I can see what you mean when you say this chip get's hot.. I briefly placed my temp probe over the chip while running at 2.0Vdd. Temperature was approximately 65°C. A small heatsink is definitely the answer for this chip.. I did look at the datasheet for the chip and it is capable of handling this temperature.Quote:

Running 2.08v here. Been doing so for the last 15 odd minutes.
Checked the IC in question, it is hot. dialed the voltage back.
HERE is the datasheet to the chip that burnt..:eek: <<On Rich's board..
You guys might find this extreme but I do it out of self preservation of my system. Ever since building AMD systems most of us knew we needed good cooling options if you were going to apply the voltage that makes lots and lots of heat.:p Besides using 2-4K rpm 80 MM fans to extract, I put my PS fans to high all the time. If it has a temp bulb to sense, that is outta-here. My NB has a 6K 60 MM mounted along with either 1 or 2 120 MM fans mounted on the inside frame. If you are blowing air onto the components, it will help avoid the hot spots that can build up like this little regulator can if you up the voltage......
Now don't laugh:D or scoff, it works great! A little extra noise is added but well worth it if you are an avid o/cer.

Tip of the day :) Get lost of all that cables and 2 coolers, and make some room for nice airflow. It will save you I think 10 degrees
http://www.xs4all.nl/~bruuuuut/case2.jpg
That is why I used round cables. Ribbon cables did block the LOWER fan. You are obviously blind to all the rest of the fans mounted in the case.....sheezit!! Can't believe it!!:rolleyes:
The whole Idea is move air within and extract from the rear and top front. Oh, I forgot to tell you I do that too. Sorry!
I've got the same set-up - 2 120mm fans blowing on top of the video card and mobo in general - silent fans and theyVantec air extractor device air extractor device on the bottom left of the case to help improving airflow as it will suck out all the air produced by the big fans - hence improving air flow...if you're careful in selecting ur fans and how placing them - then you end-end with a fairly quiet and cool system while still oc'ing...I've no AC and my case temps (closed case) are 20-23c max really...room temps are the same...Quote:

Other than the Vantec fan how many rear mounted fans do you have?
What I do is also remove all the back plates for the slots that are not used so air can exit, or enter to increase the air flow within the case.
I used to have 2 rear mounted but the air extractor does a better job than a rear extracted fan or even both combined - I measured it and am getting better case temps with it...so I only have another rear mounted at the other extremity + the extractor...Quote:

Am not removing the back plates because of dust...I know it sounds stupid but I want to make sure nothing can get inside the case :)
I also have a 4-Fan controller device so I can tune them all for higher cooling or some more quiet setting...

Well if that is the idea... it`s just impossible@ this moment because of all the wires blocking the top front..... Don`t get me wrong, I just wanna help but that`s not epriciated I gues. Relax :)Quote:

I wasn't asking for your help.....I was just adding ideas on cooling the case and m/b like fibonaccov did. His suggestions are good as well as mine.
You are fixated on one stupid fan at the bottom when I have a multitude of fans blowing in, around and exiting. There is not a stale breath of air in that case.
Getting a little offtopic, are we? :)
I would say Pjoeloe has been an added distraction.
I hope you are looking in the mirror when you say that because you are one too!
It doesn't take a rocket scientist to understand my initial post so I will quote the part for your ** THIS IS FLAMING DON'T DO IT AGAIN ** again!
Now, what part of that do you not understand?!! I didn't ask for your evaluation I was trying to provide help. But, you came in with your a*s leading the way and tried to rip in to my rig. I would say that you are acting likeQuote:

quick question Holt. I just checked out that thread. I've never been to AOA before. Why is everyone jocking Epox and getting all bent out of shape if someone mentions any other board. Is it an Epox owned site or something.Quote:
unlucky Richbastard, hopefully you can live upto your name and buy another
I started a thread on AOA in your honour
http://www.aoaforums.com/forum/show...&threadid=12995
It was actually pretty funny. Some dude says Abit does this, and then everyone freaks out. "Dude you can't say Abit" WTF?
Aaron
Because the site is run by a Gay Hitler type character named Daniel and the Epox tech guy is some kind of communist. You think I'm joking right? Hang out there are see. Most of his "followers" are sissy's licking his boots. Ask them something they don't want to answer and they'll ban you. Challenge what they say and they'll ban you. Mention another brand name too many times and they'll ban you.
In other words it's a dictatorship and some kind of weird gay hardware cult. :D
