Comments on: What are all those pins for? http://www.reenigne.org/blog/what-are-all-those-pins-for/ Stuff I think about Sun, 22 Jan 2012 21:39:31 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Paul http://www.reenigne.org/blog/what-are-all-those-pins-for/comment-page-1/#comment-4047 Paul Mon, 30 May 2011 22:05:50 +0000 http://www.reenigne.org/blog/?p=1079#comment-4047 Thanks andrew.. its a £250 gigabyte board that a friend of mine gave me when he had damaged the pins and was too scared to risk his expensive cpu.. i agree with your thoughts and i think i will try and straighten the ones i can under a magnifyer (but most importantly make sure none can touch any adjacent pins). then look for cheapest lga1366 cpu on ebay.. i assume that would be an i920 about £100 and hope for the best..i think if the board posts i will quickly go to bios and check cpu temps for a few minutes before i install xp .thanks again, i will post the outcome in a few weeks when i get a cpu bargain..

There are three aspects to this, only one of which you can check. The first thing is to check that the bent pins can't touch anything else. The second aspect is whether all the parts of the chip will actually get power. The earth and especially the power lines are probably connected up inside (since, from a chip design point of view, it's probably easier to do it that way than to try to make sure that no single pin transfers too much power) but if they aren't the chip won't work and could be damaged. The third aspect is whether the remaining pins can deliver enough power. There is usually some margin of error with these things, so it should be okay, but it's possible that when the chip is really working hard and consuming a lot of power, the remaining connections will get hot. That will increase their resistance, further limiting the power transfer. If there's too much power transferred and too few pins, this could lead to a runaway situation where the remaining connections burn up. Overall I'd say you have about 20% chance of destroying the chip, 10% chance of it not working properly and 70% chance of it working perfectly. So I guess it depends on whether the risk of damaging the CPU is worth the cost of buying a new motherboard. I'm not sure. There are three aspects to this, only one of which you can check.

Yes, you can use the image. I would be interested to know if you do anything interesting with it. Thanks! Yes, you can use the image.
