[SOLVED] 4 x 16GB 3200MHz RAM not running at advertised timings ?

[MagnumMembrere]

Hello, I used to only have 1 HyperX fury 16gb 3200 and 1 Kingston Fury 16Gb 3200 Running at D.O.C.P at it's true timings 16-18-18-18-36. I am well aware that even though they have different names and model numbers, the Kingston Fury is exactly the same Ram, just rebranded because they Kingston let go of the HyperX Branding.

Now I upgraded my PC by adding (2) Kingston Fury 16Gb 3200 which is packaged as 16x2gb kit. Now whenever I turn on D.O.C.P which automatically sets the proper 16-18-18-18-36 timings, My PC would not boot , or if lucky, it will boot but will hang without a moment's notice and will need a hard restart.

What worked for me was Setting everything in Auto (D.O.C.P. turned off), set the RAM speed to 3200MHz then set the voltage to 1.35V which sometimes sets the timings to 17-17-17 or sometimes even 22-22-22, honestly I'm just happy to be running it at 3200MHz rather than 2400MHz

Now my questions would be, will there be a difference in both Gaming and Productivity given that I don't have a dedicated GPU on these RAM timings? (I use Adobe programs and also Maya and Blender)
Also, is there any way to fix this?

Mobo: Asus Prime b550M-K (Bios rev. 2423)
Cpu: AMD Ryzen 7 4750G
GPU: Built-in APU
RAM: 64GB (1xHX432C16FB3A/16 (HyperX Fury 16x1Gb 3200) 3xKF432C16BB1A/16 (Kingston Fury 16x3 3200)
OS: Windows 10 Pro

Hey there,

Yes, as you've pointed out mixing DIMMS can cause issues, specially with XMP. You've found that out already. I bet if you just put in the matched kit by itself, it would work as rated. As soon as you introduce the new DIMMs they won't boot.

The solution for that is to enter ram timings manually, or as you've done, select ram speeds and leave everything else on auto. You can play around with the primary timings and can possibly reduce the CL or other timings. Whilst ram timings are important, faster speeds help, specially with gaming.

There's no real way to fix it, other than entering timings manually, or getting a 4 x matched kit to ensure they work as rated. You might want to check the QVL for your mobo on which kits you can get that have been tested.

Thanks for confirming man, appreciate the info!
