Can't get ram up to 3200Mhz?

[ripper101]

So I am running this 3200Mhz 2X8GB kit of ram that is 14-14-14-31 with a ASRock x570s PG and R7 5800x. For whatever reason I cannot get this kit to run at rated speeds even with increasing voltage. When setting the default XMP profile the only thing it will do is not boot and reset itself to 2400Mhz. I have been able to get it to boot by decreasing the clock speed to 3000Mhz and it works great. When checking the reviews people are able to push a lot more out of this RAM even getting it to CL14 4000Mhz at 1.54V or something. I am hoping to get more out of this RAM as 3000Mhz CL14 is pretty close to CL16 3200Mhz. I even tried 3133Mhz and it will boot but it will not be stable as I get lots of game crashes. I even have two more sticks of the same ram and am getting the same results. I also have tried the other ram slots and even rolled my BIOS back from the latest BETA to the latest official BIOS and nothing changed.

 

I already tried increasing the voltage to 1.4v with 3200Mhz CL14 and had no luck. Will not even boot. I also even tried 3200Mhz CL16 and it will not boot. Is there something in the settings I can change? I feel like it not even booting and going straight into the BIOS with default RAM speeds points to a wrong setting on my part. Any help is appreciated

what about soc voltage? That could go to around 1.2V for overclocking, but higher is not always better.

 

also make sure you use slot 2 and 4, assuming it's arranged as 1234 with 1 being next to the socket.

This kinda sound like you got a terrible UMC on your 5800x, but it could be that the memory topology on that motherboard is complete crap. Try increasing your SOC voltage and adjusting the load line (on my X570 Taichi and 5900X it does the best with 1.15v and Level 2 LLC). tRCD 14 at 3200MHz is fairly intense on your memory controller, so that that's why my mind jumps to a weak memory controller.

 

If changing the SOC voltage doesn't help, try messing with the termination settings. ProcODT greatly effects memory stability, and the BIOS might just be setting it wrong for your particular memory kit (ProcODT 36.9 Ohms works with dual rank B die on my board, which might have the same memory topology as yours). The Rtt's might also be a good idea to mess with and see if they help improve stability. 

 

Also, remember, those sticks are Samsung B die, and with B die you can safely throw 1.8V at it without any issues, so if you want to improve stability

Well I am not sure why it's working now but when I tried the 2/4 slots it worked this time. So I set my voltage the same as someone else had it in the Amazon review and it's stable from what I can tell at 3800Mhz CL14 1.54v. Not sure If I should try higher or not yet but I would be satisfied with those speeds.

dont copy settings from someone else, once you go beyond stock settings every kit will be different.

They can be used as a pretty decent baseline tho

You shouldn’t need to add SOC voltage for only 1600MHz. Should be a walk in the park for that CPU.. Could be the board, but someone else’s settings from a different system probably will work against you.
