Warning about DOCP

[mad1394]

DOCP turned my nice stable pc into a random bsod machine.
If you have the amd + asus motherboard combo and having problems with system stability turn DOCP off.
The abrupt shutdowns were quit varied, everything from freezes to a "normal" bsod. Bluescreenviewer would point to ntoskrnl.exe which is a complete dead end if googled. Could be anything.
I hope my post helps someone and wish you all a nice day!

You're blaming the wrong thing.

DOCP is just what Asus terms the "use the RAM profile values" setting. That's all it does. It reads the profile values stored on the RAM and sets them. They don't use the term XMP on AMD platforms because I think they have to paying royalties to license the term, and they don't want to do that for AMD platforms, hence they came up with their own names for the setting. MSI and Gigabyte have their own terms for it too.

If your system was unstable with that enabled, it just means your system was unstable at whatever RAM settings you were attempting to apply, not that DOCP itself is to blame. If the specifications in your profile is the hardware you're referring to in this example, then I'm not surprised. AM5 can start to have a harder time as you go above 6,000 MHz RAM frequency because other parts of the CPU can't keep up (namely the Infinity Fabric starts to require more luck above 2,000 MHz), so sometimes you need to lower the ratio to remain stable. 6,400 MHz won't always be guaranteed stable, especially if your CPU wasn't lowering that ratio and was attempting a 2,100 MHz Infinity Fabric.

Try enabling DOCP again, but then manually change RAM speed from 6,400 MHz to 6,000 MHz (or lower the ratio, but you may lose performance in some circumstances by doing this). It might be stable then.

With DOCP disabled, you're probably running with the RAM at whatever DDR5 JEDEC default frequencies are (and a much slower Infinity Fabric).

Thank you for explaining it. So it is a case of: more is not always better.
I appreciate the tips, for now I will enjoy my stable pc.
How much performance is left on the table without DOCP?

What board do you have? Buildzoid mentioned the X870-I having a quirk regarding a particular voltage needing to be set before it became stable.

ASUS TUF Gaming X670E-Plus Wifi

As pointing out DOCP is ASUS naming for Intel XMP profile since technically Intel only certified that feature for Intel for Intel motherboards.

Basically your saying enabling the XMP profile crashes the computer. What memory are you using?

Edit nvm:

AMD Ryzen 7 7800X3D
ASUS TUF Gaming X670E-Plus Wifi
Corsair Vengeance 2 x 16GB, 6400 MHz, DDR5-RAM

Ah I see the Corsair Vengence strikes again.

More like the motherboard didn't automatically switch to Gear2 automatically. It should above 6000 to avoid these types of problems. Probably got a unlucky IMC and it needs some voltage TLC in the VDDIO and SOC to make it stable in 1:1 mode.

DOCP/XMP should never be blindly turned on in my opinion. Stability tests is a must on RAM. Read up on some basic tuning as well, if it feels too much to tune to fix it and its unstable, go back to JEDEC, slower and more stable beats slightly faster and unstable.
