MCE Error Computer hangs

Im getting random hangs on my computer and this is what mcelog says, its  a repetitive pattern.

Could use some help knowing if this is a CPU hardware issue or memory issue, i have ran several torture test like mprime... but it passed them all for a few hours... so im out of ideas.

Re: MCE Error Computer hangs

"BUS error", "parity error" - maybe something with the FSB? This would mean bad CPU, northbridge or some wet electrolytic capacitors no longer being that wet anymore

I don't think it's RAM, but if you have multiple sticks you can remove one and wait until new MCE confirms it wasn't this stick's fault, then remove the next one and so on...

Similarly, you can install microcode updates to confirm that this isn't the reason either

If the CPU didn't run insanely hot or have other legitimate reasons to suddenly fail, I'd suspect the motherboard.

Is it because of RAM or CPU? Or maybe motherboard ?

Please help. TQ

Edit your post and use code tags, please.

Dear All,

Anybody having experience on the mcelog error message ?

TQ

Re: MCE Error Computer hangs

received parity error on response transaction

Does the server use ECC-memory ?

The messages appear to mention only 2 banks , bank 0 and bank 5 .
I'd run memory diagnostics .

If your mobo is server/workstation class HW it should have extensive diagnostics accesssible from firmware .
The archlinux iso has memtst and is an alternative.

Re: MCE Error Computer hangs

Dear Lone_Wolf

Thank you so much for responce, yes the mobo is S5000VSA and its using ECC RAM, the server are drastically rebooted after live about 7 days and before that i did run the memtest86+ and i didnt found any error on RAM, i search around and i found somebody change the CPU, i dont know is that the best way i should do.

Please advice. TQ so much

Re: MCE Error Computer hangs

Here is a shot in the dark, but is your processor an Intel processor?  Have you installed and configured the microcode updates?

Edit:  BTW, could I bother you to edit your posts and use code tags rather than quote tags ?

Re: MCE Error Computer hangs

For clarity, the reboot happened after the CPU was changed ?

If this is happening in a corporate/medium-sized business environment : cover your ass .
Somebody WILL be blamed for this, better make sure it's the responsible party.

report the isssues to your superior asap.
gather/request detailed info about the cpu change, support level and support contract of the hardware.
If you're lucky the support contract will include on-site assistance from expert technicians / engineers .

Re: MCE Error Computer hangs

In all the cases I've read here on the forum about MCE errors, the problem was always broken hardware. If you are not the one in charge of hardware support just follow Lone_Wolf's advice, pass the hot potato to whoever is responsible for hardware maintenance.
