Question proper ram installation

[unseenhawk]

Hello,

Building a PC for the first time, and I'm trying to do everything by myself without the help of anyone else except youtube and motherboard manual, I tried to google the answer myself but couldn't find an answer.

I've a dual channel ram sticks, and from what I've understood I should put the ram stick on either 1 and 3 or 2 and 4 with some preferring 2 and 4 for better cooling.

The rams I've now :
G.Skill Ripjaws DDR5 6000 MHz CL 30 16GBX2 they on QVL
https://www.gskill.com/product/165/377/1649234605/F5-6000J3040G32GX2-RS5K-F5-6000J3040G32GA2-RS5K

Motherboard :
Asrock Z790 Riptide WIFI
https://pg.asrock.com/mb/Intel/Z790 Riptide WiFi/index.asp#Overview

Motherboard memory specifications :
1DPC 1R Up to 8000+ MHz (OC), 4800 MHz Natively.
1DPC 2R Up to 6800+ MHz (OC), 4400 MHz Natively.
2DPC 1R Up to 6000+ MHz (OC), 4000 MHz Natively.
2DPC 2R Up to 5600+ MHz (OC), 3600 MHz Natively.

I think it's better to use 1 and 3 > 1R correct ? or it doesn't matter .. and why the ram sockets have different speeds, or they come like this from the manufacturer ?

Thanks.

Typically, the slot farthest from the CPU, one empty space, and the second stick goes in there. The slot closest to the CPU should be empty.

Not every board maker uses the same numbering, and sometimes lettering, system. Typical for quad slot dual channel boards. Boards with different memory channel configurations have very different population rules.

User manual page 18.
For 2 module configuration use slots A2, B2.

1R - means single rank ram module (usually single sided module).
2R - means dual rank ram module (usually double sided module).
1DPC - means 1 DIMM (ram module) per channel, i.e 2 modules total.
2DPC - means 2 DIMMs (ram modules) per channel, i.e 4 modules total.

Read and follow your motherboard manual.
All other considerations are secondary.

Once installed, pick the XMP profile that you want.
Speed probably means little to Intel so don't agonize about such decisions.

Heat is not an issue for ram that is not overclocked past xmp specs.
As always, try to get some cooling airflow over your motherboard, regardless.

When done,
Run memtest86+
It boots from a usb stick and does not use windows.
You can download it here:

Memtest86+ | The Open-Source Memory Testing Tool

Memtest86+ is an advanced, free, open-source, stand-alone memory tester for 32- and 64-bit computers (UEFI & BIOS supported)

memtest.org

If you can run a full pass with NO errors, your ram should be ok.

Running several more passes will sometimes uncover an issue, but it takes more time.
Probably not worth it unless you really suspect a ram issue.

Thank you, I got it.

Thank you for taking the time to read the manual, so it's 1 and 3.

Oh it's geofelt, thanks for your usual help, much appreciated.

Couldn't choose the best solution because you all helped, but this thread is now answered, thanks all again.

I have no idea, what you mean by 1 and 3.
Use slots A2, B2 (2nd and 4th counting from cpu).

Right, I apologize for the brain-fog, thank you.
