Memory corrupted after longer sleep

[derMatze]

Ok, so let's keep fingers crossed: Just switched from Gigabyte Z97M-D3H to Asus H97M-PLUS.
Will report back within the next weeks if there will be KP/Freezes again...

Thanks xenophon61!

More evidence that this is a unique problem to this particular line of motherboard/BIOS.

Using the link you posted as a guide, I found something else suggesting that disabling C6/C7 in the BIOS may be a 'fix'. I'm trying this now. sleep & wake function as I expect even with it disabled.

Has anyone already tried this approach?

 

[xenophon61]

Yes. Didn't work. Lobotomizing the CPU is not effective in any way.

Figures!

And things are still working great for you with the replacement ASUS board?

I am a free man! Just take my word for it!

P.S. my only problem is that I'll be selling my Gigabyte mobos (actually, giving them away) and can't figure out what to say to the recipient: is the board OK for Windows, or not... How is one to describe the trials and tribulations on this thread to a person not familiar with OSX?

There's a risk that sleep won't work correctly too like on mine: Blue Screen Of Death after long sleep... That's the equivalent of Kernel Panics in Windows.

It figures; well, I decided to give them away, gratis, and explain the situation.

And you have no problem with the ASUS Motherboard ?

 

[xenophon61]

Yes. Remember it's essentially the same system (components, OSX, Clover, smbios, Energy Saver settings, everything), just the motherboard was changed.

Here's some evidence: (the funny time indicators are "am/pm" in greek)

Please note that:

• "Power Nap" is enabled in energy preferences
• Time Machine backups occur as expected
• some RTC alarms emanate from ChronoSync scheduled scripts performing backups in the middle of the night
• oh, lest I forget: the recipient of the backup scripts (also a former Gigabyte patient, now cured by Asus), wakes up with WOL and receives the data without incident

I hope you agree that, indeed, the GA-Z97X-SLI and H97-D3H motherboards were the culprit, at least in my case (two OSX86 setups). Current RAM DIMMs are the same as previously.
