Posted May 13 Hey guys! My current setup im using is running: Ryzen 5 5600 Asus b450 a-ii Nvidia 1060 3gb Samsung SSD 980 500GB Kingston 2x16gb 3200 mhz DDR4 Ram And i have some questions about XMP or for amd i think its called D.O.C.P and how to use it and how to ensure it working. When i first upgraded my pc to my current setup i could not set my ram to 3200mhz, for unknown reasons but now as of recently i tried again to bump it up to 3200mhz and it seems to be working, I also put the FCLK on manually to 1600 as suggested in another post on here about the FCLK. But here's the question i see online that my rams are intel XMP dose that have performance impact on my system? And now that i enabled D.O.C.P will that work even if it says Intel XMP? Any Info, or suggestions or anything would help so i can hopefully understand my system better and understand D.O.C.P/XMP and FCLK Link to comment Share on other sites More sharing options...

Posted May 13 D.O.C.P is XMP for Ryzen, they are identical, there is Ryzen tuned RAM known as EXPO, but XMP will run on AMD CPUs. FCLK is basically your fabrics clock speed, fabric being AMD's infinity fabric, or your RAM controller, this should be equal or higher than your MHz, so 1600, or even higher should be perfect TLDR Run RAM with the 3200MT/s XMP profile and altered FCLK clock as you already have it currently and you should be good System specs: CPU: Ryzen 7 7800X3D [-30 PBO all core] GPU: Sapphire AMD Radeon RX 7800 XT NITRO+ [1050mV, 2.8GHz core, 2.6Ghz mem] Motherboard: MSI MAG B650 TOMAHAWK WIFI RAM: G.Skill Trident Z5 NEO RGB 32GB 6000MHz CL32 DDR5 Storage: 2TB SN850X, 1TB SN850 w/ heatsink, 500GB P5 Plus (OS Storage) Case: 5000D AIRFLOW Cooler: Thermalright Frost Commander 140 PSU: Corsair RM850e PCPartPicker List: https://uk.pcpartpicker.com/list/QYLBh3 Link to comment Share on other sites More sharing options...

Any Info, or suggestions or anything would help so i can hopefully understand my system better and understand D.O.C.P/XMP and FCLK The reason why XMP didn't work to begin with could be a bios update or you didn't install the ram sticks in the correct slots. A2 and B2 is the correct ones, XMP won't work in the other slots unless 4 ram sticks is installed. Most of the time XMP work ok on AMD. You can see if it does apply anything in bios by checking out the ram timings tab. As an example, i've made this: Yellow marking is the primary timings, those won't change, even if on Intel XMP instead of DOCP. If the red ones is on auto and doesn't have a value assigned, it uses the motherboards auto settings for this speed and not XMP. If anything is filled out in the red field, then Intel XMP did change the timings. You can test if it has a positive or negative effect by running CB23 for example and check your score. You'll need to run multiple times in order to compare the scores. You can set frequency, dram voltage and primary timings manually, leaving everything else on auto in order to test this. This is the same you need to do if you experience instability by running XMP. I hope it makes sense.
