[SOLVED] Pc won't boot on XMP profile

[talhaskrillx]

Hi!
I have the following system
-Ryzen 7 2700
-32Gb Gskill Ripjaws V (4X8 GB)
-Asus TUF gaming plus X570 (Latest Bios)
-Msi Rtx 3060ti
-Xpg reactor core 750-watt gold PSU
I recently updated my memory from 16Gb to 32Gb (all sticks are the same). But when I enabled the XMP profile it won't display anything.
When I had 16Gb memory (2x8Gb) the system booted and worked perfectly with 3200MHz
Now with 32 Gb memory (4x8GB), It won't even post with 3000 MHz.
Please someone help me out.
Any response is really appreciated.
I am attaching CPU-z and other useful screenshots

if 4xDIMM cant do 3200mhz with the latest bios, enabled XMP even with configuring all the same timing, then pretty much it's the cpu limit.

 

[sizzling]

4 dimms puts extra load on the memory controller, it’s normal for the max speed to be lower.

First try installing 2 RAMs and set XMP and check. Then try the 2nd set of RAMs with XMP.

Note down Timing of each RAM set once in XMP. Check whether they are the same.
Cause even though they all carry the same name, the timing and capability might differ.

If everything is as it should be, then it is the memory controller to be blamed for not handling the stress of 4 sticks.

You may think all sticks are the same but if they are not a 4x kit they are likely not the same.

You can fuss with the voltage and timings to find the max speed they will all play nice together.

With 4 ram modules command rate has to be 2T.
You have 1T. That is not going to be stable.

Please show screenshot from CPU-Z - spd section. Screenshots in your initial post do not have this info.

What brand and model of both RAM kits?

I am sorry. I added the same link for CPU-z by mistake
I have updated the links on the original post.

Thanks for the info. Can you give further insight on how I can do this?

I did try this and I am pretty sure that both kits have the same timings.
I know some people using up to 3200Mhz on the same processor and same ram kits
What processor do you recommend that I can use with this motherboard and same ram kits on rated frequency?

Can I OC ram kits without stability issues and damaging components?
I see people using up to 3200 on B450 motherboards using the same processor.

Can I use 2 DIMM's 2x16GB on rated frequency i.e 3200Mhz?

Should be able to.
Set dram parameters:

DDR voltage 1.35V​

Command rate 2T​

Latencies 18-22-22-42​

Set frequency to 2133mhz, test.
Increase frequency and test again 2400,2600,2800,2933,3000,3200,3400,3600.
At some point it will fail, then return to previous settings, that worked.

Can you explain where should I put latencies?
18-22-22-42?

In BIOS -
AI Tweaker/Dram timing control.

Note - Trcdrd and Trcdwr is the same thing.
So you'd have to set 5 timings values instead of 4.
