New ram causing pc not booting up with cpu oc

[Mando772004]

I used to have 2x8 16gb ram 3000mhz cl16 ran fine with my cpu clock ratio set to 42 on all cores (i didnt set any voltage or anything kept it all on auto). now i got a 2x8 16gb 3733 cl19 kit which runs fine but only works with the cpu oc (4.2ghz on r5 3600) if i have dram voltage set to auto not 1.350 which is what its supposed to be running at when its on 3733mhz. is this normal or is there something wrong with my power supply?

Faster RAM is harder on the CPU’s IMC (integrated memory controller), and some IMC’s are not as good as others. 
 

So your enabling XMP and then setting the voltage to auto, and it works?

yes i enable xmp and set my dram to auto and my cpu ratio to 42(4.2ghz) but when dram voltage is set to auto it boots when i manually set it  to 1.35 it doesnt work

Do you know what it’s setting the RAM to on auto..? Have you tried no cpu OC and enabling XMP? I would be curious if auto voltage, who knows how many volts it’s pumping through the IMC.

yeah i did worked fine. i think the voltage it sets is incorrect

It worked fine with no CPU OC? If that is the case, your OC is likely not stable at that RAM speed. Remember, faster RAM is harder on the CPU and can reduce stability. I am not a Ryzen owner tho so I have never messed with the voltages specific to Ryzen, but I know for Intel when trying to run fast ram and an OC, you usually have to up the VCCIO and SA voltages to get things stable again; you may have to do the same. Or lower your CPU’s clock speed a bit. I would suggest trying to find specific Ryzen info, I am just not the right person since I don’t have one.

 

But if it worked with no CPU OC, this is the issue... how to fix it though, that’s harder. I wouldn’t run auto voltage tho... check hwinfo64 and see what volts it’s actually applying. It could be pumping way to much.
