RAM overclocking and stability issues

[Aranorde]

My Specs :

1. Ryzen 5 2600
2. Team Group T-Force VULCAN TUF 2X8GB at 3200Mhz CL 16-18-18-38 1.35v (Hynix C-die)
3. MSI B450 GAMING PLUS MAX

Currently I'm running at 2400Mhz and everything on auto settings, I used to run at 3200Mhz on XMP for a month without any issues until my PC decided to just restart during boot and re-set itself to 2400Mhz randomly today.

• I'm assuming the XMP is unstable at times and not consistent. Is this normal?

My RAM is rated as 1.35V on the package, but the Auto XMP on the motherboard puts it between 1.368 - 1.372V.

• Does this mean my RAM is running at a Voltage that it is not supposed to run and could be the reason for the unstability?

I tried setting the timing to 1.360V to check if everything going normal, but the PC just re-set the speeds back to 2400Mhz again. But When I enable the XMP to profile 1 (2933Mhz) the voltage goes upto 1.368 - 1.372V as Auto! It is working on XMP but when I set the voltage manually it does not work.

 

I'm currently using DRAM calculator and got a list of timings for my RAM at 3133Mhz, do I need to alter the SOC voltage and everything? Hardware Unboxed video and some others suggested no need to do it but I'm a bit confused.

• What exactly do i need to set after the timings?

For stability, aim for 2933mhz which is the cpu memory controller supported frequency.  

 

To increase the performance at 2933mhz, try 16-16-16-16 timing set. 

 

Before you make further changes however, clear the cmos first. Enable XMP and manually set frequency to 2933 and test stability before tweaking timings as described above.
