Introduction
Hey @All,
I am struggling with upgrading my RAM from 16GB to 64GB since three whole 12-hour-days and are out of ideas, maybe you can help me, I would be really, really happy.
I never did anything with the following settings before and might not have understood everything yet, but am capable of googling and reading instructions, so feel free to tell/ask anything and I will try to answer as clearly as possible.
Hardware Setup
Mainboard: MSI Gaming Pro Carbon Z170A
CPU: Intel Core i7 6700K
Memory: 64GB Patriot Viper 4 Blackout, DDR4-3600 DIMM, CL18, Dual-Kit (2x32GB), (PVB464G360C8K)
The RAM is installed in DIMM Slot 2 and 4. The chip manufacturer is Samsung.
Compatibility Insights
The msi website states that my mainboard supports a RAM frequency up to 3600.
There is a "(OC)" behind this statement, I suppose it means that this frequency can also be overclocked, or ist only achievable by overclocking, I am not quite sure - but either way, running with 3600 should work, I guess.
The compability list does not have ANY 64 GB (2x32) RAM listed, but the specification states that the mainboard supports up to 64GB RAM, so I suppose they just don't have tested that (since 64 GB seems to be used rarely anyway).
Problem Description
No matter what I do, I can only boot into the OS (Windows 10) with settings that seem to be the default DDR4 settings.
According to CPU-Z, Version 1.94.8.x64, this works:
Frequency 1333 MHz (so 2666 in total since its Dual-Channel) - CL 19.0 - tRCD 19 - tRP 19 - tRAS 43 - tRFC 734 - CR 2T - 1.20V
Target frequency is the advertised 3600 with CL 18 - 20 - 20 - 40, so I expect CPU-Z to show something close to 1800 as current frequency.
I don't mind about overclocking at this point, just want it to work with the advertised XMP settings.
Trying to set ANY other values (even lower ones than advertised) via BIOS will cause a failure to boot into the OS , throwing me back to a BIOS screen, stating that there were some failures due to the overclocking settings, so all settings were reset to default values.
Things I tried so far (settings in BIOS/UEFI):
.. and applied the basic recommendations to begin with
None of this worked, I always get the "All settings were reset to default values. The previous overclock settings have failed." screen.
Can you guide me in any direction? (even if it is "it will not work, buy a XXXX Mhz XX GB RAM instead".
Thanks in advance!

Things I tried so far (settings in BIOS/UEFI):
- Updated to the newest BIOS/UEFI version
- Running 3 Passes of Memtest86 (with the default low settings) to check the hardware, no errors found (skipped the 4.th one cause it already took about 6 hours and a hardware defect is very unlikely anyway)
- Operating with one RAM instead of both, tried both individually on different slots
- Resetting CMOS - this will load the "auto" settings described above
- Adjusting frequency / timing / voltage settings manually
- even a slight increase from the default 2666 Mhz to 3000 Mhz will not work
- also tried 3333 Mhz since my old RAM was operating at that frequency (with CL 16, 2x 8GB) perfectly for the past years
- increasing voltage to the recommended 1.35V (for 3000/3333/3600 Mhz)
- also increasing to 1.45V does not help
- loading the XMP profile
- enabling MSIs "Memory Try it!", which seems to enable SDP profiles, where I selected Samsung and the advertised 3600 MHz
.. and applied the basic recommendations to begin with
- set CPU core ratio to "per core"
- changed to multiplier from 40 to 42 (since 4200 is the turbo speed for my CPU)
- disabled any automatic turbo boost settings
- did not perform any stability tests with OC CPU settings (since I only wanted to know if this enables my RAM to work in XMP settings, I do not want to overclock the CPU if not neccesarry)
None of this worked, I always get the "All settings were reset to default values. The previous overclock settings have failed." screen.
Can you guide me in any direction? (even if it is "it will not work, buy a XXXX Mhz XX GB RAM instead".
Thanks in advance!
