Trying to diagnose this bluescreen for months..G.Skill F3-12800CL9-2GBRL
I built a new pc several months ago and since basically day one I've been having a completely random BSOD at bootup with Windows 7. Now by at boot up I don't mean right when Windows 7 gets into the OS, I mean from my bios about 2 seconds into the little colored logo moving for Windows 7 the computer has a blue screen. My hardware is as follows:
Asrock 870 Extreme 3 -MB (case temps around 25c)
AMD Phenom II x2 unlocked to Phenom II x4 B55 quad core (idle 30c load 42c
G.Skill F3-12800CL9-2GBRL -Ram
Samsung F3 1TB Sata 2 -HD
LG DVD Burner
Sapphire Radeon 6850 -VC
Coolermaster Silent Pro 600watt - PS
Windows 7 Ultimate 64bit
Now I've been trying to figure out what has been causing this for a very long time. This has been the hardest pc error I've ever encountered when it comes to diagnosing it because it always comes at completely random times and I've already thought many many times I found the solution because suddenly it stops for several days but..nope there it is again. I have noticed it seems worse on "cold boots" after the computer has been off the entire night or say 6 hours or so. It generally Bluescreens the first time it goes to reload Windows 7 but then after it reboots the computer functions flawlessly. I have ran Prime 95 for hours upon hours on end without a single hiccup (and passed very high stress levels in Intel Burn test as well as AMD overdrive). I have ran Furmark on the graphics card and passed 10 minutes without an issue. I have played hours and hours of games without any issues as well. The ram HAS passed memtest86 for 6 hours straight several different times. All voltages from the powersupply are very stable.
Now here's my question. Even though the ram passes tests like Memtest, is it possible the memory is STILL at fault here? Every time I research into this issue everything seems to point at the memory having an issue. I have checked voltages and timings on the memory to make sure everything is fine. I have ran the memory at the DDDR3-1600 speeds and also tried to run it at DDR3-1333 when I read a lot of users having issues actually getting the 1600 speeds to function properly. All my timings are set exactly where G.Skill recommends (9-9-9-24-2N). With the Asrock 870 Extreme 3 motherboard I can either have the memory at 1.47 or 1.53 (can't remember exact voltages off the top of my head but one is very slightly below the recommended 1.5 and the other is barely above, there is no 1.5 setting). I have tried other hard drives (even bought the Samsung which is brand new and tests flawlessly), I have pulled an old 8800gts video card out of my other desktop to see if the issue was the card and it still has the BSOD with the Nvidia card. I did manage to borrow some Corsair DD3-1600 memory from a friend and this did seem to get rid of my issue for a couple of days, problem being is I had to give it back before I could really know 100% for certain. The pc has managed to go that amount of time with the G.Skill without having the BSOD so it's hard for me to say =/. The AsRock motherboard manual also suggests running 1600 ram in the blue A3-A4 slots instead of the White A1-A2 so I've tried both without any success.
This is seriously driving me insane trying to figure out what is causing this. I have done at least 3 completely fresh clean installs of Windows Ultimate x64 without any luck. I have been insanely careful with every single app I've installed and driver to try to make sure that isn't the issue. I just really have a feeling it's this G.Skill ram...maybe not a typical fault but something a little out of the ordinary causing my issue. If someone could recommend any thing else I can try I would just like to know before I mail off the ram at my expense and go a week + without my machine only to have them tell me the ram is ok. I thank anyone who took the time to read through this, I tried to keep it short but unfortunately that's hard without being specific. I'm already leaving out paragraphs worth of details for solutions I've tried with no luck in solving the issue.
ps The unlock on the Phenom II has worked flawlessly since day one. All cores tests perfect with AMD overdrive at the stock 3.2ghz, hours and hours of prime 95, intel burn test etc. I'm 100% sure there isn't an issue with any of the cores. I didn't have to "fight" with the cpu to get this unlock to work, no voltage adjustments, lowering multiplier, etc.
Please help!
