Ram speed 3200 I blue screen- 2666 and it's fine... why?

[gaff3r]

I have Thermaltake Toughram 32 gb's total and its going into my B550m with a Ryzen 3600 chip. The issue I have is when I set my ram to 3200 speed (which it's ranked for) I keep getting blue screens on startup and interruptions in my games. If I set the ram to auto it brings it to 2666 speeds and I don't have any issues. Can anyone explain what is happening and is there anything I can do about it or just set the speed to 2666 and leave it. 

 

Thank you,

Try updating the BIOS if you haven't already. This helps improve memory stability. 

 

Also, welcome to the forums!!!

Bios was updated back in December and is still the latest available. 

 

Thanks for the welcome!

Ok that's good. Are you sure the RAM is in slots 2 and 4? The 3600 does support up to 3200MHz so I'm not sure why you're having an issue, unless the IMC is pretty bad in the chip.

Do you enable XMP or set the memory speed manually?

Is the RAM listed as compatible on the Mainboards website? It can be unstable if it isn't, although it shouldn't be bluescreening.

I have AMD so DOCP but it's disabled

I have 8x4 so 32GB and filling all RAM slots. I'm honestly not sure what IMC means.

Integrated Memory Controller, found in the processor to handle the memory lanes. Yeah 4 DIMMs are going to put a lot of stress on a 3600's IMC. Try only with 2 DIMMs instead of 4 DIMMs and enabling DOCP to see if you can achieve 3200MHz. Otherwise, try setting the frequency and timings manually.

DOCP is an Asus thing, their "name" for XMP.

If you're setting the memory to 3200 manually while expecting to keep the timings and voltage of 2666 (JEDEC), you're doing it wrong.

XMP/DOCP is what makes the RAM go 3200. And there are kits that set the voltage 1.20V which is too low for AMD and needs to be bumped to 1.3500V.

 

IMC means Integrated Memory Controller. The memory controller is a part of the CPU.

If it’s not on the QVL there are no guarantees that it will run in a stable manner.

sure is listed: R019D408GX2-3200C16A. I didn't check compatibility until now but I got lucky it is

That is good to know I always thought XMP was Intel and AMD was DOCP but thanks for that info (learned something new!) Also learned about IMC, thanks! 

 

so I think that might be the issue when I manually set the ram to 3200 it left the memory at 1.2v (it's ranked for 1.35v) but if I enable DOCP it puts the ram at 3200 and voltage at 1.35v. So should I just leave it at DOCP enabled with all 4 slots filled. Will that be too much for the 3600 IMC?

Well, you're using 4 sticks. 

It's a bit harder for a motherboard and for the memory controller inside the CPU to use 4 memory sticks, compared to just two.   The QVL may have validated the sticks at 3200 Mhz only with 2 installed. 

With some motherboards and cpus (depends on luck) it could you may have to settle for 3000 mhz or even lower when using 4 sticks. 

 

It's possible you could get them running at 3200 Mhz by loosening the timings .. for example, read the timings for 3200 mhz using Aida64 or Cpu-z  (Aida64 is more thorough and gives more timings) and then loosen them.

For example, instead of 16-18-18-36 , try 18-20-20-38 

Make sure the voltage is also configured at 1.35v for the ram, and not the default 1.2v  - the sticks only need 1.2v to run at 2666 Mhz, but need a voltage boost to run at 3200 mhz.

 

PS.  Direct Overclock Profile (DOCP) is AMD's version of Intel's Extreme Memory Profile (XMP) technology.

thanks for the definition, I did not know that! 

I had not enabled DOCP before and just adjusted the RAM to 3200 speed. But I noticed when I adjusted the speed to 3200 the voltage stayed at 1.2 which may have been the problem vs. when I enabled DOCP it went to 3200 mhz and 1.35v. I'm going to see if I have the same issues with DOCP enabled.

I'm going to try the DOCP enabled because it shot the voltage up from 1.2 to 1.35 which may have been my problem all along. If that doesnt work I will try with 2 sticks and then try loosening the timings like suggested. Thank you for your advice!

If the RAM is rated at 3200 it is supposed to run XMP 3200.

On lower clocks it has lower latencies and if those aren't loosened it won't be stable at manually set 3200.

Just load XMP (DOCP) and leave it at that. All 4 slots should work, timings should be set as they should be at that clock, and the voltage should be also set.

Adjusting timings (lowering the latencies) is manual overclocking.

Good advice, been using DOCP config for 3 hours and no blue screen so far so thank you for your help.

Actually its Asus' and its just a fancy name for XMP : D

 

DOCP stands for Direct Overclocking Profile. It is an overclocking profile developed by ASUS for AMD motherboards. DOCP uses XMP protocol to automatically set data rate and timing on AMD motherboards.
