amd docp lowers cpu performance

[david_croft98]

hello so i have a problem when i turn on docp profile in bios my cpu gets lower performance and it doesnt boost all the way the power consumption stays much lower never reaches max 65w on full stress i dont get full peformance out of my cpu and i dont know why once i turn off the docp everything backs to normal cpu boost all the way etc am i missing something or what is going on

my pc specs: ryzen 5 7600 non x RX6800 32gb patriot viper ddr5 5600mhz cl36 motherboard ASUS tuf gaming b650m-plus

I don't understand your question. On your screenshots, the one with DOCP on shows a better CPU score.

There's a fair number of things that can cause this, so I'll try to run through the ways I'd go about checking this.

 

First things first I'd run Cinebench (probably R23 but anything R15 and newer would work) to compare the scores with that instead of CPU-Z. The CPU-Z benchmark test isn't that commonly run when compared to Cinebench, so I don't really know how the scores are supposed to line up, and since Cinebench is famous for not caring what your memory speed is, this will indicate if it's the memory performance going down (assuming the score stays within 2-3%) or if it's the CPU downclocking (assuming the score drops 5%+)

 

If it's determined that it's the memory performance that's dropping, the next thing I'd do is download a program called ZenTimings to compare the memory timings the motherboard is training at stock and at XMP. There are a few kits that exist that the XMP profile contains some subtimings that are looser than JEDEC which result in XMP performance being worse. It's also possible that the motherboard is just randomly dropping to 2:1 UCLK mode or the FCLK is weirdly low, both of thich would cause memory performance to be possible and diagnosed by ZenTimings. 

 

If it's the CPU clocks that are going down, it's almost certainly a power/current limit of some sort, so use HWInfo to see what limit is being reached so you know what needs to be raised.

i mean that when i turn on expo or docp how people call it i get much lower performance in games in benchmarks the cpu z the higher score means better without docp and the lower means worse with docp turned on

Apologies. My bad, I had seen 5300 instead of 5900.

Well, it is possible that demanding more juice for the memory controller came from computing power ?

But still, I wouldn't be worried by a difference of 300 points over 5900). Did you test with real gaming experience to see if this really translates into slower performance ? Even if you got a bit less computing power, you got a large boost on memory speed.
