Possible dead DIMM(s) not sure

What a crazy few days I have had. I am all out of ideas at this point and I hope somebody can help me.
Here is the situation.

In November I bought a GTX 660Ti and installed it, ever since I would get a BSOD at the loading windows screen that said machine check exception, 0x09c. I found if I kept trying I could get windows to load. I figured with the new card my PSU was max'd out and not getting power to it at start up. I eventually bought a new PSU, but that did not fix it. I did more research and found it could be a bad sector on my HDD, and since I wanted to get an SSD anyway I bought a 240GB SSD and reformatted. That did not solve it.

I looked around in event viewer and noticed errors with Intel Smart Connect, so I installed the latest driver from Intels website. The next day I get BSOD about unpaged something or other and 0x050. I was able to boot into safe mode with networking, but can't boot normally. After more research I assumed it must be this new Intel driver and I needed to find a way to fix it. Pulled my hair out all day trying everything I could dig up online. Then I found something that said to check my memory in memtest, so I ran memtest twice and both times memtest was halted for an unexpected error (around 20% and only a few minutes into the burn). That made me think it must be the ram.

I pulled one stick out and tried to boot. No cigar. I swapped the sticks and tried again and it started up. So I decided ok I need to buy new ram. Shut down and woke up today to go online and order new ram, got the 0x050 BSOD again. So this time I pulled the stick out and got some old ram I was using in a previous build and tried to boot with both of those in the other two DIMMs. Didn't work. I then tried to boot a single stick in my DDR3_A2 slot only and it would start up, but that is the only DIMM I can get to boot, if I try to boot with two sticks in, in any configuration, it gives me 0x050.

I tried both of my original sticks in the DDR3_A2 slot, one works one didn't so I know that at least one stick of my RAM is in fact bad. I went and bought some new ram this afternoon to see if maybe by getting new RAM all together would solve it and it doesn't. So, is it the DIMMs or is there something else I can do to maybe resolve this? My mobo is under warranty and I can have it fixed but I would prefer not to if I don't have to as I not only play on my PC but I also work.

Specs:
i5-2005K @ overclocked 4.5ghz
Corsair H60
G.Skill DDR3 1600 2x4GB (old ram)/ Corsair Vengeance DDR3 1600 2x4GB (new ram)
Asrock Pro4 Z77
Corsair 240GB SSD
EVGA GTX 660Ti
Corsair 750W PSU
Windows 7 Pro 64bit

Thank you for the help..

Boot with the 'good' stick and go into BIOS, set the DRAM to 1600, 9-9-9-27, and DRAM voltage to 1.55, then raise the CPUVTT to 1.14, save shutdown and install the GSkill sticks in
slots 1-3 (from CPU) and try that, may be bad voltage regulation....if no joy there, then reset the CMOS (pull mobo battery for about 30 seconds and reinstall, go to BIOS and reset Time and Date)

I went into bios and did just that and what do you know, it booted right up on both sticks. I'll continue to monitor it for a while to make sure it is really fixed and I didn't "get lucky", but I'd say it might be fixed! Thank you!

So as I said after I did that it started right up, today I went to start it up and I got the 0x050 error. I reset CMOS how my mobo manual said to and it booted, we will see if that fixes it or not.

So the problem seems to be my overclock. After I cleared cmos I was able to boot multiple times on stock settings, when I put my OC back in it bsod on the first boot and was fine the second. Today it wouldn't boot again until I loaded the default clock settings.

A quick search around for the BSOD codes and overclocking and things are getting a little more clearer. I found this chart with bsod codes for overclocking an 1155 chip. In my OP I mentioned the original bsod I would get every now and then was 0x09c, the chart says "0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances" and for the current one, 0x050 it says "0x50 = RAM timings/Frequency add DDR3 voltage or add QPI/VTT".

I never overclocked my RAM or GPU (because I don't know how), and you told me to set VTT to 1.14, should I bring it up higher and maybe set QPI to something? What I do not get is why I could boot up until now, it has been a while since I overclocked.

EDIT: I went into bios and bumped my OC down from 4.6 to 4.5 and changed me vcore offset from -0.40 to -0.030 and it started (also have lower temps), we'll see if it keeps starting. I guess I just have to play with it until I get it right. Very weird it would let me boot for months and then now wants to give me hell over it. Oh well!

It's fixed! AsRock emailed me and had me update my BIOS as well, so I did that and put my overclock back in at 4.5 instead of 4.6 and I have no issues. Thanks!
