    No, no real way to test CPU as the issue for sure, unless you had other memory and even then it may not help.

    Thanks warren, I had forgotten all about that. A short on the rear of your cooler backplate or front can also do this. Be sure none of the traces on both sides are shorted by your cooler

    As for my settings, sounds like they would work (As they should) with some tweaking, something you should have done from the begining. Since you did not start that way, it sounds like you gave up way to quickly. I can't give you spot on settings that will work for your CPU, you will need to tinker. The way I gave you settings though is the proper way to go about things, and until you can get it going with similar settings I can't say for sure what the issue could be or not as I am not sure you are setting up your memory properly without it being set like above.

    Your BSOD should be in event viewer, if you remember what time you were doing this you should be able to find it. Then you can tell us the issue and we can advise back, likely you needed more Vcore (0x00000101 Or 101) or more QPI/Vtt (0x00000124 Or 124)

    I suspect it is settings, you used it for a year without issue, so I think things just slowly became unstable due to your setting choices or lack of. Now you need to find and re-tweak your settings to find proper settings and stability at the clocks you were using and your memory should all work properly.

    I'll take this one on piece by piece.

    Hm...That's a possibility. What do I look for? I don't know what traces are.

    As for my settings, sounds like they would work (As they should) with some tweaking, something you should have done from the begining.
    Why the hostility? And frankly, that simply isn't true. I have held this back thus far, respecting your position here as support for Gigabyte. However, I will respond in kind.

    Your telling me to increase voltages when everything is/has been running fine. Is that not totally against
    one of the most basic rules of overclocking? The best stable performance you can achieve with the lowest voltages possible, in order to preserve and lengthen the life of your hardware, as overvoltages do the most damage, and produce more heat, reducing the life of a component. I personally fried a couple of DDR2 sticks of Mushkin HP by going .1v over spec with my previous e6600 build. Honestly I was very hesitant to run the XTUNE at the voltages you wanted. But I did. I do not know nor claim to know everything. This information has been gleaned from reading a few guides for overclocking i7 920's. Perhaps I am wrong.

    And I did do tweaking from the beginning. I spent two straight days on this build increasing my bclk, then my vcore, slowly, each one, closely monitoring the temps and adjusting everything accordingly. Like I have said many times, it was perfectly stable under Prime95 torture testing. So I should have increased my voltages just for the fun of it?

    The way I gave you settings though is the proper way to go about things, and until you can get it going with similar settings I can't say for sure what the issue could be or not as I am not sure you are setting up your memory properly without it being set like above.
    Firstly, I did every setting exactly as you suggested. If you said something to be from 1.2-1.4 volts, I tried both. No, I did not try every setting inbetween. I did everything you asked, but I'm not going to go over it. I do not know why you have reason to doubt me and am not inclined to prove it to you.

    Secondly, your forgetting a few things. This is a premium motherboard that I paid 300$ for. I shouldn't be required to have exactly the right voltages and every single timing set for my ram in order for it to work. If this were a new build, incompatible memory would be a possibility...but not even, the ram is detected in some slots fine, and was known to work and be detected fine previously to a bios flash. At stock the ram should be detected. Period. Claiming this is not a fault of the motherboard, but of my settings, has frankly just made me angry.

    can i ask what type of cooler your using?check its not overtightened as that will give you ram faults
    Thermalright Ultra-120 RT in a push pull config.

    Your BSOD should be in event viewer, if you remember what time you were doing this you should be able to find it. Then you can tell us the issue and we can advise back, likely you needed more Vcore (0x00000101 Or 101) or more QPI/Vtt (0x00000124 Or 124)
    I couldn't find it, either I'm looking in the wrong spot, or it's not there. There are two possiblities, I have no page file on my OS partition, and it warned me it might not save some error reports when I set that. Also, the windows load screen with the bar underneath flashed for only a second before the BSOD. Not sure it would record that.

    I think the grounding thing is a real possibility. At one point I moved my case back after doing some work to it and heard something fall on my desk. It was a motherboard standoff screw thing. I knew that was possibly bad but didn't know it could cause this exact symptom. Have a couple days off over the weekend, I'll rebuild it from the ground up.

    he means the memory traces printed into the motherboard,sometimes if you overtighten your cpu cooler esp with a backplate it can damage or block the signal to your ram from the cpu,or even short on the motherboard itself,its worth checking just incase.when it blue screens try to see what number it gives at the end of the error code on screen Vcore (0x00000101 Or 101) or more QPI/Vtt (0x00000124 Or 124) thats what lsdme is saying

    A trace is all those little wire like lines on your motherboard, it is copper wire ran under the PCB. If your heatsink front mounts or back mounts or plate are scratched through or pressing very hard on these they can cause a short. Easiest way to test for this if you are unsure, is to put on the Intel Stock cooler for a quick test and see. If it works with that, then most likely something on your cooler is shorting and you will need to find the cause and fix it if you can.

    Sorry, I did not mean to come off as hostile at all!!

    I only said things like that, so you would know that this is likely the cause of the issue and were not stuck in thinking with the "it's always worked before" thoughts. My main thing was your uncore was way off what it should be, any voltage changes I suggested are only to try and see what the issue is here and not meant to be used for 24/7 running or something I am telling you that you must use at all. Only trying to help you sort this out is all. You will not fry anything with any of my suggestions, and going over by .1 on memory will not fry it either that memory had to have some other fault and was on it's way out.

    I did not mean to make you upset, or contradict your thoughts or ideas. Sorry, sounds like we have got off on the wrong foot here. I am only trying to help you find the cause of this issue. If you think it is the board and or memory and do not wish to further troubleshoot let me know and I can get you the RMA pages for either so you can get moving on that route so things can get back to working order.

    I was just trying to help and save you from that hassle, sorry if I came off as hostile or anything like that!

    Ya, both of those things you mention in regards to BSOD could mean there would not be one. So no luck with that I guess.

    Sounds good, I will for sure do a rebuild before RMA'n anything just in case. I'd say go ahead and set the system up outside of the case on a wooden desk or cardboard box, then if everything starts fine you know you had a short or something inside your case.

    Again, I am very sorry for the way I sounded to you, that was in no way my intentions! I am always here to help, and happy to do so. It takes a lot for me to be upset, and you are no where near my bad side, so not sure why I sounded the way I did to you, but I see it would be my fault of course so I do apologize for how things sounded.

    I am here to help, hopefully we can figure this out without you having to RMA but sometimes that is all you can do. If I sound offensive to you again, please let me know as that is not my intentions at all, ever.

    I guess it's my turn to say sorry. You have been very helpful thus far. I'll try building it on cardboard, going to be a pain as my cables are routed very carefully in my p182se.

    Warren, that's a sick rig. Why an ati 1950pro? That's just a waste. You tried Bad Company 2 yet?

    No need for you to apologize, I can see how you thought I was being that way, so it was only me who needed to say sorry.

    So, did you have any luck with further testing yet? Just checking in

    OK, I have my rig completely dissasembled. Nothing was out of place with the heatsink touching tracers, the backplate was still there and perfectly intact.

    However...I did notice a slight smudge of Artic Silver 5, and it was across a few traces on the top of the board which lead to the ram. The traces are labelled DD1 through to DD6, and being right beside the ram banks, I'm pretty sure they are ram related. Also, the smudge of AS5 was across the traces labelled DD5 and DD6, the exact slots im having problems with. Looks promising...Can some folks chime in on whether or not this could be the likely cause before I rebuild?

    I rechecked my cpu pins under very close high intensity light. My eyes are perfect up close. Couldn't see anything so I'll check one more time tommorow, I'm going to bed and plan to build it tommorow when I wake up. Is it reasonably safe to assume I would see bent pins? Given the symptoms and the fact that my processor is detected and running as it should...what is the likelyhood it is processor related?

    Another thing of note is that underneath my i7 920 chip, where all the gold contacts are, some have a coppery kind of color to them, it looks like it may be wear from my voltages, or from running something too fast maybe? or is that color changing normal and nothing to worry about?

    Thanks again.

    Meh. It's back up and running. Four gigs in dual channel. Same symptoms persist. Time to call a spade a spade. I still have a couple of years warranty, and can't stand being without a rig...so I'll buy a new mobo in the near future and send this one for RMA, to use in a backup rig. Not happy about it, but whatevs. Thanks for all the help guys.
