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

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

------------------------------------------------------

Speed Before D.O.C.P
Type DDR4
Size 16 GBytes
Channel # Single
DC Mode
Uncore Frequency 1596.8 MHz

Tmings
DRAM Frequency 1596.8 MHz
FSB:RAM 1:16
CAS# Latency (CL) 22.0 clocks
RASS# to CAS# Delay (tRCD) 22 clocks
RAS# Precharge (tRP) 22 clocks
cyde Time (tRAS) 52 clocks
Bank Cyde Tme (tRC) 71 clocks
Command Rate (CR) 1T

Speed in task manager 3200MHz

------------------------------------------------------

Speed After D.O.C.P
Type DDR4
Size 16 GBytes
Channel # Single
DC Mode
Uncore Frequency 1599.6 MHz

Tmings
DRAM Frequency 1599.6 MHz
FSB:RAM 1:16
CAS# Latency (CL) 22.0 clocks
RASS# to CAS# Delay (tRCD) 22 clocks
RAS# Precharge (tRP) 22 clocks
cyde Time (tRAS) 51 clocks
Bank Cyde Tme (tRC) 71 clocks
Command Rate (CR) 1T

Speed in task manager 3200MHz

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?

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! :tearsofjoy:

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

Motherboard:
Asus B450mk-ii
BOIS VERSION: American Megatrends Inc, 3211, 8/10/2021
Ram: Klevv U-DIMM 16GB 3200MHz
Type288 Pin DDR4 Unbuffered DIMM
Speed 3200
Capacity16GBx1
Voltage1.2V
CL Value3200 / 22-22-22-51

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.
