Random memory training issue

@lmaneke


Please go here and get CPU-Z (zip version)
CPU-Z | Softwares | CPUID


Then "run" cpuz_x64.exe and post screenshots of the Memory tab and the SPD tab... like this...

@lmaneke


Ok... I believe I see the problem.

The Memory tab is what the RAM is actually running at. The SPD tab (rightmost column) is what the RAM "should" be running at. So....

...the problem is that the TRC timing "should be running at 56, but you have it running at 75.

In the BIOS you have to open the DRAM Timings section on the AI Tweaker tab, and change the TRC to 56.
Or even better... "manually set the freq., the timings and the voltage in the BIOS.

Here's mine again... the frequency and timings and voltage in the BLUE box... are the manufacturer's specs.
When I built this computer, I just set the BIOS to match what was in the BLUE box...








I had to "guess" at the DRAM RAS# PRE Time to get the RAM to run... stable.

For YOUR RAM, you need to use the frequency, timings and voltage in YOUR... BLUE box...





Remember, in CPU-Z... the BLUE box on the SPD tab is what your RAM "should" be running at.
The Memory tab in CPU-Z is showing what your RAM is "actually" running at.

Yeah this is so weird, as I have the memory profile set at DOCP in BIOS, so I would think that the DOCP profile would automatically load these values.

I also have an ASUS X570 board (see my specs), and DOCP didn't run stable, at all on my computer.


This is when I figured it out...

ASUS motherboard RAM timings problem


I "used to" overclock, back in the day. So, I was already a firm believer in setting the RAM frequency, timings and voltage manually.
When DOCP came along, I tried it. On my board, it made the RAM unstable, so I went back to the old way.

I see that. Wonder if this is a thing with the X570 Boards. I have an Asus x370 and x470 board, and both of those are reading the correct values in cpu-z.

I'll manually set everything in BIOS and see what happens.

Thanks

THAT I couldn't tell ya. Before this I had an ASUS Sabertooth 990FX R2.0 board, which didn't even have DOCP.


Until this topic of yours, I never even "heard" of memory training. I had to Google that and read about it.
From what I read... it seems that memory training is just a way of fine tuning the RAM settings in the BIOS.
I also noticed that it doesn't seem to work... a lot of the time.



Btw, I would "guess" at your DRAM RAS# PRE Time also...and set it at 18.



So in your BIOSes... DRAM Timing section, I would think you would set the timings like this... from the top down...

16, 18, 18, 18, 38, 56
Frequency 3200Mhs and voltage 1.350v

And if your BIOS is anything like mine...
You need to click on the timing setting where it says Auto... then type in the setting you want, then hit ENTER.
