Professional solderer for motherboard

[Mesce]

Hey, anyone know a good place in the uk preferably northwest near bolton that will do some soldering for me on my motherboard?

Problem is my droop on my ic7-g motherboard is really terribly. I set vcor to 1.46 (prescott) and it droops to 1.41 idle and then to as low as 1.36 during prime 95. If you guys understand this can be a pain when you have got good enough cooling to overclock quite a bit. I have a 2.8a prescott overclocked to 3.4ghz and I can pretty much run stock volts through the cpu so long as its idle as soon as I do something intensive like fm2005 or prime 95 I restart because droop goes so low.


All I need doing is this

Any recommendations?

yellow pages etc for any local tv/sat/hifi repairers, might be willing to do it and their skills should be up to the task.

I was thinking of a electronics guy because it is really a simple job for someone who is great at soldering and it is like any other mods where you need to scrape a layer off and attach things to lines. I would do it myself but I feel I dont have the expertise, all i done was soldering on some r/c cars.

did you get your voltage readings directly from a multimeter?

[daniel_owen_uk]

Also are you sure its not your PSU?

[Mesce]

Its definitely not my PSU. And no i didnt get my readings from a multimeter and i know that you are going to want me to get my readings from there for the most accurate reading. I used mbm5 and abiteq for my readings and at 3.4ghz if it fell below a certain 1.36 my system either bsod or restarted. Also with a vdroop I will be able to get a higher 24/7 overclock.

I agree with dan, voltage drops are normally caused by drawing to much current. But
you never know have you read about this prob some where else and they have said this
is the solution?

Going to cost you a fair bit to get someone to do it for you professionally btw.

[Mesce]

seriously? I didnt think more than maybe £25. I mean its only 2 little pieces of solder, and they would have to replace the mobo if the messed it up. Mobo is quite expensive. I would rather a pro do it.

kumagoro, I definitely know that is the droop that is causing it other people witht he same mobo have experienced it and where i normally come from www.eocf.com I have spoken with a few guys and this is the problem. I have monitored the droop my self with utilities and seen it droop whilst load and idle. It aint the psu. but ill link you with it. http://www.aerocool.com.tw/aerocool-...I+SE/ii+se.htm

Mine is the 550W.

It's all labour cost really. A 20k resistor costs ~2p, enough solder costs a fraction of a penny (solder is about 5p/metre or less). Having someone sit there and do it is what'll cost you.

[Mesce]

I know that I would supply everything. How much for labour?

[Butcher]

Dunno for sure, it'll vary from person to person. You may as well not bother supplying stuff, the cost will be for the labour.
Me personally, I'd do it for a fiver, but I'm not a professional solderer.

[Mesce]

I wouldnt post my mobo out i would visit the persons workplace or house and watch them doing it. Do you have faith in yourself and what would you do as an insurance that you wouldnt screw up.

[Kumagoro]

I guess the biasing in the IC is cack then. If you do get it done get a low noise
low tolerance resistor.

[Rave]

Well, if you're expecting someone to guarantee their work, then you can expect to pay a fair price for it TBH. Butcher, he needs a 20K variable resistor, but that's still well under a quid. A competent person could make the two solder joints required in less time than it would take you to tell them what you need. However, if I was a professional repairman and I was expected to cover the replacement cost of a £70 (estimated) motherboard, I'd be looking to charge £15-20 for my work otherwise it's not worth the risk.

My advice would be to do it yourself. Pull an old PC (or any other bit of kit with surface mounted components) out of a skip and practice on it, then once you're competent do the job on the IC7.

That crossed my mind. If I would pay upto £25 for this to be done perfectly and the cost of my mobo replacement is £94. Thing is once I get this done I will have a higher stable 24/7 overclock and also it will stop the damn droop.
