Asrock Z77-ITX restarts when stress testing

I've gone to mini itx so only a single PCIEX slot for a single 290.

Not that having 3x 290's idling would affect the CPU's stability while stress testing anyway.

its hard to say new psu or board

ive never used an asrock board

+1 I don't think the GPU side would affect a thing.

Anyway, back on track, have you had chance to try another PSU in your system at all?

It may sound stupid, but could the VRM's be getting too hot causing system shut off maybe? You are running a lot of voltage through the board, so it popped into my head.

I don't think it's the VRM's, there's loads of reviews for the board running higher voltage then I am and it copes just fine.

Hmm okay, as Wazza said I think it is definitely either the board or the PSU.

Are you able to test another PSU at all?

I assume you've tested it at stock speeds?

Reboots like that would indicate to me that the PSU is faulty, especially if it is new.

Just formatting some HDD's that I have around and one had a Windows 8 installed so I run Intel Burn Test at 4.5Ghz on that it passed without any issue.

I'm running on a mSATA SSD that's located beneath my CPU socket so I wonder if it's a thermal shutdown, not from the CPU overheating but from the mSATA SSD as the heat will spread from the CPU to the mSATA slot??

Never mind, just tested it again and it failed, curious why it passed the first time around.

The system had only just been powered on so everything was cool...... Second time the parts had time to warm up?

Could be, test it at stock a few times and see if it consistently passes.

Is that a sunflower or super flower pus?

Not heard of sunflower.... If it's a cheap pus, it may not matter if it is 'rated' at 750w.

Also, you are a little quick to dismiss certain possibilities. Just because reviewers had no problems with more volts and temps on that board, doesn't mean it won't necessarily be the problem. Not all electronics are created equal.

Also, CPUs don't always clock the same on different boards. So it is quite feasible more volts may be required than your previous.

Same goes for ram. Just because it ran 2400 on previous doesn't mean it will do same here.

It's entirely possible that you may have reached limit of what that CPU/board/memory combo will do.

Forget about what you got fom previous board - as you are no longer using it...

It's not the boards overclocking abilities dude, limitations between different boards tend to vary 200Mhz at most, not 600Mhz like this is.

The PSU is a Super Flower 750w unit and is brand spanking new.
