Yep i thought too, but my H87N Wifi never worked as it should, so i swapped to a H87I Plus from Asus and it works fine. Needed to Edit DSDT and disable autopoweroff.
Now sleep is stable and haven't had a reboot for 7 days ...
My guess is Gigabyte MB hast a bad batch or maybe some serious...
Lots of problems, changed ram, increased voltage and so on :banghead::banghead: still not working. This issues is discussed a lot in the forum, search the solutions and try out.
Since i switched to Asus no more troubles with the same Ram, Sleep works even long time.
Autopoweroff is 0 now and i still have the Problem, there might some other settings in Pmset?
AC Power -1*
Currently in use:
Sleep On Power Button 1
It looks like Gigabyte has some Problems with there 87 Boards, i had a mini itx with 2 Slots and the same Problem. So had many other users, eventually they can solve it with a bios update or the board needs RMA ... The whole Forum has many reports about this Problem not only with 4 Ram Sticks...
Someone might know the cause of this reboot instead of sleep?
If i send the pc to sleep it turns off, a second after it turns itself on for a secon and off again. Afterwards it reboots itself. :beachball:
Me too, same Problem, probably Gigabytes issue.
First had Ram troubles with Kernel Panics, so this issue disappeared. But now with relatively stable system this issue appeared.
Someone a solution besides RMA...
I tried all kind of things with my 8Gb Kingston Blu, replaced the Ram (RMA), increased different Voltage, changed frequnzy, changed timings no solution.
Then i bought a 4gb Ram stick Kingston Blu an the system runs perfect without any crashes.
And yes the 8Gb is on the compatible Ram list...
Yes its possible and i heard also a lot about 2 Dimms freezes on mini itx builds like mine. I also have some freezes, far less frequent but they are still around.
Might timings might voltage, but Gigabyte will probably keep silent until they know a solution. Otherwise it could get RMAs out of...
Ok lets have a look at the bios in:
Advanced Memory Setting --> Channel A Timing
Check the Timings for each channel (A/B) if they are 10-10-10-30 (Cas-tRCD-....)
If not switch "selectable Timings" to manual and put in 10-10-10-30 manual.
Try if system run stable ...
