Help with speed of 4 sticks RAM (4x8GB TeamGroup 4000mhz)

[richt48]

Hi all,

I had my PC running sweet with 2x8GB on my Ryzen 5900x and Asus X570 E-Gaming. 4000mhz and 2000 IF worked first time with the latest BIOS update (v.3801). I didn't need to change voltages, they were left as they came. I decided to add another 2 sticks and that's where my issues started. It will not boot anywhere near the 4000/2000 I had previously. It's at 3400/1700 and that's the best it will go. Anything else won't boot.

I've not tried upping the voltages yet as I don't know what to go up to. This is my first PC upgrade since I bought my Core i7 3820K new. So yeah, not familiar with this new BIOS yet.

This post is more of a starting point. If anyone has pointers on voltages and what settings to adjust I will gladly take onboard any advice. For now I'm going back to Googling for more information. I'll post more later.

Cheers

Adding more sticks put more load on the controller, try 1.38/1.4v running at 3600/1800

Thanks for that. I'll use that as my starting point.

With your advice to mind I got it up to 3600/1800 at 1.38. I went as far as 1.405 trying to get it to boot any higher but no luck. What voltage would you say it can go up to? I need to do more reading up. Cheers.
