Ryzen ram speeds dropped to half

Terrorgod

So i'm running a ryzen 1700x on a asrock x370 pro4 motherboard and wanted to go back to my old stable overclock since i started high refresh rate gaming again. But when I pushed my overclock and went into control panel and cpuz, it now states that my previously 3000mhz ram is only running at 1500mhz. I tried swapping settings back and forth and changing profiles but no matter what now the ram is always half the speed i set it to. Googling the issue is still flooded with ryzen ram compatibility videos so I thought it best to come here. Any help is appreciated.

You know that DDR4 running at 1500MHz means an effective 3000MHz speed, right? My best guess is you are looking at the raw speeds. After applying double data rate DDR logic you end up with 3000

DDR stands for double data rate, that means for each cycle it does two transfers. So when you say ram is running at 3000mhz(effective), it is in fact running at 1500mhz, using double data rate signalling. 

 

So the truth is, it is running at 1500mhz, but performing 3000MT/s(mega-transfers per second).

That is one thing i saw but it also used to say in the windows control panel that it was running at 3000mhz and now is saying 1500mhz. Is that something from a recent update?

Could be that it went deep. Wouldn't be the first time, wouldn't be the last. Listen to the BIOS and what it reports

The bios does report 3000mhz and I do remember situations were supposedly trustworthy programs lied "COUGH RYZEN MASTER TOOL COUGH" so maybe its just a weird thing on my desktop (laptops with the latest update still mark their full speed but who knows). I'll just mark this as resolved since it doesnt seem to be affecting much speed wise. thank you for all the assistance guys!

RAM speed on AMD ryzen master is infinity fabric speed. DDR4 ram runs twice every cycle, and its true speed is half of what you set it at. Ryzen master isn't lying, and your bios isn't either

At 3000Mhz RAM speed, memory controller and infinity fabric run at 1500Mhz. CPU z shows the half speed. DDR = double data rate.
