Hey there! smile.gif

I didn't post in here so often, so I am going to make the presentation with a "small issue" which makes me mad and with no-way-out.

Since three years by now I've got a full Z77 rig (exactly a P8Z77-V and an i5-3450). Since I am going to move somewhere else and although this the new apartment will be definitely a bit smaller to host all my pc and the various devices, I decided to sell it. Thing is when I found someone to sell a block (mobo-cpu-ram) I don't know why the buyer called me saying that he is having issue with the motherboard. I said to him that's not possible because the day before I totally pulled out everything and test if everything works, and it does totally.

Then, the story is that I went to him the day after in the morning, I analyzed the problem and there is an issue with the RAM. Red LED on there.
This is not definitely a good news to hear.

I started to analyze the ram, the buyer also told me that he swapped CPU and the RAM in his config (H77) for a cross test and everything works normally. So the CPU it was luckily safe as the ram. In my mobo since I had four RAM sticks (ballistix tactical tracer 2x4GB), the system refuse to boot so I started to get a stick and put it in one slot at a time and boot.

Once I came to the third RAM slot, it magically boot as the fourth. And here another BAD BAD news that I totally didn't want to hear.
So, conclusion is: Slot A2-B2 are working, A1-B1 are not.

I removed the cpu and guess what? three bent pins on the socket.
I was closer to swear in front of him but I controlled myself, really. I also had a small discussion with him about it and upon agreement he just bought the ram, so with anger and regret I give him the money back for the respective mobo and cpu price.

Now, I am not that kind of guy who usually swear or fight, but since I treat my stuff CAREFULLY (I mean it, carefully) I was thinking if the bent pins are the cause of my "transport method" (I put the mobo into its box and accessories in my backpack) or if I push too hard somewhere to cause a damage like this, or his fault.

But nevermind, bad luck always happen, right?

So, analyzing the pinout scheme, I found three pins bent.

Here is the image:


I recognized the position:
1st: pin B3 - VSS_NCTF (GND)
2nd: pin AY3 - RSVD_NCTF
3rd: pin AY7 - SA_DQ[24] (DDR3 I/O)

I only captioned the pin AY3 and B3, and I am absolutely sure that are the ones necessary for the DRAM operations which is preventing me to use slot A1-B1. Can you guys confirm me this and also to caption the other pin left? no clue what the others are for even after some googling.
In a first glance mobo seems working like a charm aside the two DRAM slots, and stable. CPU is healthy and seems like not affected to this damage even using both iGPU and dedicated GPU (i've got an R9 270) the system can at least boot to UEFI, don't know about the rest since I sold almost everything (RAM included) and I cannot perform much test honestly.

Before attempting a socket replacement (I asked in a repair store specialized in this operations and they will probably ask me 65EUR inc. VAT, labour cost and a new socket provided by them) I want to know from you if it's possible to attempt a try with get those pin straightened. I am sure that one of them got broken because a small piece of it fall down. I also tried to straighten up by myself and I desist to continue furthermore because I haven't a much steady hand as the magnifying glass.

Hope you can help me, for me throwing out this mobo is totally unacceptable frown.gif It served me well through all this time and It's like to lose a dear friend. Also, beside this, I don't want to buy a lower-class one since they only sell H61s or more expensive mobo from the same class like mine.

Also, after the socket replacement, there is any chance that the DRAM slots can be definitely dead even after the surgeon?

Thank you very much!
