Question What exactly is D.O.C.P/X.M.P?

[Levian71]

Whether i enable D.O.C.P or not, my ram speed doesn't change that much.
As far as my information DDR4 is (Double Data Rate) so basically 1600MHz will run at 3200MHz, if that is the case what is the use of D.O.C.P/X.M.P?

CPU: Ryzen 5 3600
System Memory Specification Up to 3200MHz

cyde Time (tRAS) 52 clocks

Welcome to the forums, newcomer!

The above acronym's are profiles baked into the ram kit in order to be overclocked. In the past, like before X.M.P was a thing, people had to manually tune their rams to get to a sweet spot, mention across the forums(or close nit circles) and then the news would spread(that's how I recall them to be). Now, instead of manually inputting the timings, you enable X.M.P and then the rams go to their advertised speeds.

Make and model of your motherboard, BIOS version for said motherboard and the ram kits you're working with?

In addition to above.
DOCP is Asus name for XMP which is protected by inventor Intel and have to pay royalties to use it.
BIOS doesn't have to take it literary but can make some changes to suit particular CPU.
Higher speed RAM may have 2 profiles in addition to JEDEC standards.

 

[Roland Of Gilead]

XMP - Extreme Memory Profile (Intel)

DOCP - Direct Over Clock Profile (AMD).

Both are more or less the same. XMP is typically Intel's version of OC'ed ram. DOCP is the AMD equivalent but is more often used on ASUS motherboards. However other motherboard manufacturers use XMP for their AMD motherboards nomenclature. Makes sense, right!

But the ram is at its advertised speed without enabling D.O.C.P/X.M.P.

Motherboard: Asus B450mk-ii

DDR4 ram by default, runs at 2133MHz. In order to get to the speeds(which are advertised on the ram sticks) you will need to overclock them or enable the overclocking profile in BIOS, meaning you're still overclocking. If you think that DDR4-3200MHz rams run at 3200MHz without any flip of the switch or any tinkering whatsoever, you're mistaken.

He is not, DDR4-3200 CL22 1.20V is the highest standard so if these are the rated specifications of a memory kit, it is plug and play if the rest of the system can natively support it.

If the memory is anything but CL22 1.20V @ DDR4-3200, then the profile would be under XMP.

The memory likely does not have XMP/DOCP at all so if it can be enabled it would be no difference as reported by the user.

With utility software like CPUz, you can check all profiles under the SPD tab.
