Title: [WTS] Damaged ASUS P8H77-V
Post by: Starcraftman on June 29, 2012, 07:50:06 PM
As the title suggests, this board came with 6 bent pins. Newegg wont let me an RMA, and ASUS would charge $120 just to get it fixed, I might as well buy a new one for that price. Right now I am willing to either trade for hardware or BTC. Since the board came new with bent pins, I cannot guarantee the board works.

I will sell to the highest bidder starting at a minimum of $50, you pay shipping.

Edit: I went ahead and bent the pins back. One pin was bent so far that bending it back into position snapped it in half. I looked at an Intel datasheet for the 1155 pinout, and it looks like the broken pin is for one of the DMI_RX sets, which is supposedly for communication with the PCH. The link to to PCH has four lanes so hopefully it just disabled one.

Here is what the CPU socket looks like now: http://i.imgur.com/k3eLG.jpg

Here is the Intel datasheet that contains the CPU pinmap, page 89: http://www.intel.com/content/www/us/en/processors/core/2nd-gen-core-desktop-vol-1-datasheet.html

The broken pin is number Y3.

It's kinda important to mention WHICH pins are bent. Are they among the 1155 processor pins?
A picture would also be very helpful, as perhaps it is possible to bend it back.

So you bought the board on newegg, it was listed as a new board or a refurb?  & I would have been pretty ticked off if my order came in and had bent pins!  Thats rough.

I will do this when I get back home next weekend. And yes, I am referring to bent CPU pins. I would imagine its possible to bend them back because they are at the perimeter of the socket, but I have never done this before and I don't want to make it any worse.

Yes it was brand new. When I sent it back to newegg for a RMA they claimed the user bent the pins and sent it back.

I had a customer with a 1366 motherboard with bent pins. Those things are a pain to get back! In the end it's not even worth it. Try a manufacturer's warranty?

Alright, here is a picture of the bent pins

I am considering trying to bend them back, but I have no 1155 CPU to verify that if it works.

Ok, I went ahead and bent the pins back. It looks fairly good except for one pin that appears to be missing the tip. I will try to borrow a 1155 CPU this week and test the board.

Here is what it looks like now: http://i.imgur.com/k3eLG.jpg

The red circle shows where the partially decapitated pin is.

Edit: I looked at an Intel datasheet for the 1155 pinout, and it looks like the broken pin is for one of the DMI_RX sets. Hopefully this only breaks at most one of the links to the PCH. I will update this thread when I fully test everything.

To prevent breakage, a good way to unbend bad pins is to use a mechanical pencil with the lead removed. The tiny cylinder fits the pins reasonably well.

Yea I looked around and that seemed to be the best way to fix bent pins. That would have worked perfectly if that one pin wasn't bent fully in half such that unbending it caused the tip to snap off.

I tested the motherboard with an i5 2500k. Everything I tested seemed to work, which includes:
-Integrated CPU graphics and PCIe Graphics cards
-All memory slots
-USB ports

I will be open to offers over $60 $50, since technically the board is partially defective but I did not notice any problems during my testing.

Very cool :) Might be worth looking up the function of each pin to see how critical they are. I remember screwing up an Opteron socket 939 processor. I was just starting to dip into watercooling and I screwed something up and had to disassemble the whole loop, but my thermal grease was too... sticky? suctiony? I don't know. But when I went to pull the waterblock off the CPU, it pulled the CPU with it, even though the CPU was locked into the socket (?!?). Broke 3 pins, bent (but fixed) many others. Thankfully they were all grounds, and the CPU seemed to work just fine without the extra grounds.

i trashed a vry expensive CPU like 10 yrs ago because of *1* bent pin

i didnt know how easily they came off =/

Gotta love built in redundancy.

Bump.
