Random hard locks (bugcheck 0x124, Phenom II x4 955)

post #1 of 19
Thread Starter 
Hey guys.

I've had this issue ever since I built this PC back in November 2011 and it's driving me NUTS.

It's pretty simple: The PC, which is NOT OCed, will simply hard lock with the following symptoms:

1) Screen will freeze: No BSODs or black-outs, just simply freeze and not respond to anything.

2) Keyboard will not respond to anything either (Capslock and numlock lights not responding...)

3) Sound goes away, won't loop

4) PC does actually NOT RESPOND (not just a screen freeze), as it'll disconnect from anything Internet (Messenger, Steam, whatever)

5) Bugcheck is 0x124 with NO BUGCHECK STRING.

6) Happens absolutely at random: May not happen for days, may happen under load, gaming, idle, browsing, whatever... Just yesterday it locked up whilst doing nothing other than download a game on Origin...

7) Temperatures are average when it happens: 30 to 50 depending on what was being done

Things I have tried with zero success:

- Enabling/disabling C1E and Cool n' Quiet
- Upping/downing VCORE and CPU-NB voltage.
- AMD Turbo Boost is disabled
- Formatting the HDD
- Memtest x86, several passes overnight. Tried with all module combinations (both, module A slot A, module A slot B, module B slot A, module B slot B)
- Windows Memory Test, pass (all module combinations)
- Prime95 8hour test, pass
- Intel Burn Test, 3,2GB RAM (out of 4GB), 5 passes, several times, pass.
- Windows Driver Verifier which pinpoints Daemon Tools as *****e, removed, still no go.
- Upping GPU voltage (just in case), no go.

As I have previously said, the computer is capable of going full-throttle (playing Crysis or using Prime95) for hours and hours on end, unless it decides to crash randomly (which ironically hasn't happened yet with Crysis or Prime but has happened with other games that are perfectly OK in my own computer, this is my girlfriend's), which leads me to rule out GPU and probably the PSU.

That it passes such amounts of memory testing leads me to rule out RAM and memory sockets.

That it crashes under load just as often as it crashes doing ABSOLUTELY NOTHING leads me to rule out HDD, as things like SuperFetch are disabled and freezes with zero HDD access as well.

So, my possible culprits here are CPU and Motherboard. Feel absolutely free to correct me nonetheless.

System Specs:

CPU: AMD Phenom II x4 955 (stock)
GPU: Sapphire Radeon HD6870 (stock)
RAM: 4GB Kingston HyperX DDR3 1600MHz 1.65v 9-9-9-27 (stock, set manually, have also tried JEDEC standard 1333mhz 1.5v cl9)
MOBO: Asus M4N68T-M V2
PSU: NOX NX Series NXS520 (520W)
Cooler: Scythe Katana 3

Operating System: Windows 7, 64bits (fully updated)

RMAing BOTH CPU AND MOTHERBOARD, OR ANY COMPONENT WHICH I AM NOT SURE IS ACTUALLY DEFECTIVE, IS NOT AN OPTION. THEY WILL CHARGE ME FOR ERRONEOUS RMA. THIS IS OK UNDER SPANISH LAW.

Allow me to thank you very much for your input in advance. Need moar info? Just ask.

From what I make of it ,, bad VRM <<OR>> OC'ing your CPU at some point in the past damaged same silicon. Are all of ur peripherals checked ? I had a faulty mouse that used to trip my SMPS or simply BSOD !!

is this an idle bug ?? Doesn't seem like a load bug. Could be a sleep problem ( turn off all power mgmt features in the control panel) and keep C1E, CnQ and any power saving option your mobo may have.

I built a PC with the same mobo a few months back for a friend.. make sure you've turned off ErP and EPU .. Also , the caps and CPU phases on this mobo are a big NO for your setup . I set it up with a mild oc'd athlon x2. Sooner or later your CPU will fry the mobo w/ its power demands. What's the power split ?? 3+1 ?? If I were you , I'd be looking for at least a 4+1 preferably heatsinked if used with the stock cooler or higher, if custom cooling.

You physically inspect the motherboard to rule out a capacitor problem? If your VRMs are heatsinked, is the heatsink attached properly?

How about the PSU? Do you see the voltages changing weirdly?

PSU voltages are perfectly fine under the BIOS. What am I looking for when on the look for a "capacitor problem"? (I know what capacitors are, but what am I looking for to determine if they're bad? Swelling? Leaking?)

Mouse and keyboard cause no issues on my other system. This CPU has never been overclocked other than bumping and dropping VCORE to see if that would fix the issue (which it did not).

Windows is set to "Maximum Performance" so it doesn't ever sleep. Disabling or enabling C1E and CnQ had no effect. Also, it's not just an idle problem, it does happen under load with the exact same symptoms. It's basically completely random: Might not happen for a week, might happen browsing, might happen completely idle, might happen in the middle of games...

You mention that this motherboard model can mean trouble for this kind of setup. Thing is, I've built three systems with the exact same specs (two for other people, one for my girlfriend) and this is the ONLY one exhibiting any kind of problem whatsoever. The kicker is that both other systems are overclocked to 3.85GHz! (I insist, the setups are EXACTLY the same, even the exact same case).

Which is why I am at loss. I know the setup is good. Something is broken and it is probably CPU or Mobo.

Absolutely all temperatures are fine. No third-party coolers other than the Katana 3 CPU heatsink.

This specific system is from November 2011. The other two systems are several months older.

EDIT: When referencing "My other system" or "my main system", I am talking about Eleanor Mk.III

Just to add a couple of things for you:

A) Your board might be able to handle a 125w processor, but from the sheer looks of it you're kind of playing with fire. Not a strong board for a processor that has a heavy TDP.

B) When you gauge your PSU voltages by the BIOS, you're not gauging anything. You can't check your PSU with software or BIOS readings - they just aren't accurate at all. You're better off using a multimeter and testing the PSU while under load. It's really the only way to know if the PSU is holding up or not.

C) If you're getting the same recurring BSOD, you need to submit the DMP file here, not any information that is garnered through BSV or other similar programs. They don't read into the dump files enough/correctly. They'd need to be debugged to find out if the problem is hardware or driver based. Dump files are @ 'C:\Windows\Minidump' unless you've manually moved a dump folder.

( edit )

Those other systems you built and clocked to 3.8+Ghz are really playing with fire. Especially without proper VRM cooling.

A) I always play with fire wink.gif

B) Wouldn't a weak PSU be causing the symptoms mostly or only under load and repeatably, instead of randomly at any situation whatsoever?

C) Will do, my friend. Give me a few hours however, as I don't have physical access to the computer ATM and the owner is at work.

Thank you all for your help!

Well not necessarily only under load. Sometimes stronger currents can wreak havoc on electrical systems, so surges or bad blackouts can cause problems where it may seem that the PSU is working fine. But in any case, always test a PSU with a multimeter, not software or BIOS gauged readings.

So BIOS readings for PSU volts aren't trustworthy- gotcha.

I don't have a multimeter around however, so if I am unable to find any other problem in a week or two I'll take the computer to my place and test it with my own PSU for a few days. I'd do it right now, but she lives far away and I simply won't be able to until about a month from now.

Let's look into what else it could be in the meantime, OK? And thanks again. BTW, I don't know if you noticed but I edited by last post and included the minidump.

Awesome - I have to run out and away (couple hours drive time) but I'll check it when I get back for you. You might try E-Peen too, he can help if he's not busy, he knows how to read the dump files as well.
