Crosshair V Formula Z - Stable/cool system, go to bed, wake up with 0c qcode. Repeat.

I don't get it. I'm using the right memory timings, and otherwise factory settings for my processor. It runs fine, cool, and stable. I've benched it, stress tested it, stability tests. Everything's fine. I go to bed, turn it on, get the 0c qcode, and no post. Reset bios, set everything back exactly how it was the day before, and it works until it's been off for a while again. What info do you guys need from me to get this fixed?

Almost forgot bios screenshots. Thanks for any help you guys can offer.369163691736918369193692036921369223692336924

wait, do you have all the additional power cables plugged in? The two at the top of the mobo? I know one of them is a 4pin 12Vaux for the CPU which should be needed for the 9590

damn, that's a stumper. Must be a bad part somewhere is my guess. Everything looks solid in BIOS to me. Hope someone comes along to give ya somewhere to start!

Yes, all the motherboard power slots are powered correctly. The only thing I can think of is that I don't have anything plugged into the CPU fan spot. It gives me a CPU fan error, but lets me boot anyway. I water block (2 fans and pump) are instead plugged into a fan controller, because the pump is ridiculously loud at 12w. I've tried shutting down and waiting an hour or two, and it boots, but leaving it for maybe... 6+ hours and I get that 0c qcode and have to start over.

It should be noted that 0c corresponds to no actual error code in the manual. It's reserved for future use.

I'm having the same issue, My system is stable until I leave it off for a while. After a few hours or so when I try to start it up it doesn't post. I'm getting qcode of 10 (PEI Core is starting) and 79 CSM initialization. After resetting the motherboard once or twice then it boots up and everything seems normal again.

Sigh. I think I may have found the issue. willburstyle06, we have the same mobo, and my processor is merely a factory overclocked version of yours. They're exactly the same otherwise. We have almost the same kind of ram, as well, same manufacturer and everything. I looked into it, and here's the bad news.

AMD processors have a max speed of 1333mhz for ram. Those with that new fangled AMD bulldozer nonsense (us two) are lucky enough to be capable of speeds up to 1866, but from what I've read, 1600 is much more stable.

Here's the good news, though, even "underclocked" which is a misnomer with these types of ram, as they are advertised at their overclocked speeds, you will not notice a difference in performance from the ram. I'm going to try to boot my pc when I get home from work, and if I have to still do this reset bios nonsense, I'm just going to try 1600, let it boot, turn it off, and go to sleep. I'll try to turn it on again when I wake up, and if that STILL doesn't work, I'll let it run with what the bios detects it as, which is 1333 mhz.

Bottom line: Yep, we probably overpaid for ram that our processors aren't capable of, but we've learned a viable lesson by buying AMD products. You get what you pay for.

I'll keep you guys posted on my results. That said, if anyone else can offer any suggestions on how to fix this problem without having to underclock below 2400mhz, or even 1866 for that matter, I'd love to hear any success stories you've had with a similar build. ^_^

Have you tried manually entering the timings info, rather than using AMD's terrible version of XMP?

I had the same RAM before, just one set of 2x4. I ran it as 2400 with no problems. Not saying that you having 16GB of it isn't making your CPU more unstable, but just some extra info to think over.

Hey fella's

Disable ECC in ram options. This will cause instability and random lock ups and boot failures. I doubt anyone here is using error correction ram. Hope this helps
Chris...Have a nice day.
