Hibernate not working after memory upgrade

rhogg4859 · 13 Nov 2017

After adding more memory/ram hibernating the pc results in a 'boot failure detected' and the memory speed being changed down to 1331Mhz from 1866Mhz.

I had run memtest86+ after fitting another 2x4Gb memory chips. These being identical to the existing two chips. I have tried turning hibernate off and then on again. I have also tried 'powercfg /h /size 75%' and 100%.

powercfg /a
The following sleep states are available on this system:
Standby (S3)
Hibernate
Hybrid Sleep
Fast Startup

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.

Standby (S2)
The system firmware does not support this standby state.

Standby (S0 Low Power Idle)
The system firmware does not support this standby state.

It is strange that when I do try to hibernate the pc it goes quite for a long time before rebooting with the bios error and the memory speed showing as 1331. I have Corsair CMZ8Gx3M2A1866C9R times four with the bios set to XMP.

There are no particular errors in the event log, as the pc is just rebooting and not returning from a hibernate state.

What else can I try?

Thanks
Rob.

Further to my op.

wmic MemoryChip get BankLabel, Capacity, MemoryType, Speed, Tag
BankLabel Capacity MemoryType Speed Tag
Node0_Bank0 4294967296 24 1333 Physical Memory 0
Node0_Bank0 4294967296 24 1333 Physical Memory 1
Node0_Bank0 4294967296 24 1333 Physical Memory 2
Node0_Bank0 4294967296 24 1333 Physical Memory 3

Why is it reporting 1333 when the bios correctly states 1866?

Probably because the memory is really 1333 MHz chips overclocked (XMP) to 1866 MHZ, and it is reporting what the chip reports.

If you just do wmic memorychip get ConfiguredClockSpeed,, it will display the true memory clock speed.

My memory is 1866 OC to 2400:

wmic:root\cli>memorychip get Speed, ConfiguredClockSpeed
ConfiguredClockSpeed Speed
2400 1867
2400 1867
2400 1867
2400 1867

Yes, Geneo, that shows the configured speed correctly.

What solved the problem with failing to hibernate, which worked perfectly in Linux as one would expect, and has nothing to do with the memory was the size of the pagefile in Windows. This has been problem with Windows as far back as I can remember. The suggested size of the pagefile is not enough and causes other problems. I have found specifying the size to be the size of actual memory and larger works.

In this case I had forgotten to change the size from 8Gb to 16Gb. Problem fixed.
