RAM Slots 1/2 running slower than 3/4

Specs:
Mobo: Asus B450 TUF-PLUS

CPU: Ryzen 5 2600

RAM: Team Vulcan 4x4gb 3000mhz

PSU: Corsair CX750 (grey label)

GPU: MSI Armor RX 580 8Gb 

OS: Windows 10

 

I have previously been running 2x4Gb Team Vulcan 3000mhz RAM in DIMM_A2 and DIMM_B2 (slots 2 and 4) using the DOCP profile without an issue however it would not run this speed in slots 1/3 

I have bought another identical kit, same brand, speed, size, product number on sticker etc and have put it in my PC earlier today and am having a few issues causing confusion.

I have put my old sticks in slots 1/3 and new sticks in slots 2/4, enabled the DOCP profile in the bios (updated and reset to default today also) however it did not boot, so i changed the DRAM Frequency from 3000mhz to 2400mhz and it has booted and is running somewhat okay however these readings are causing alot of confusion, i've attatched pictures in the hope that it explains it a lot clearer than I can with words.  My motherboard supports Dual Channel memory according to their website

Slots 1 and 2 (which has an old stick and a new) is apparently, according to CPU-Z, running at a slower speed with different timings than 3/4 and if you notice the DRAM Manafacturer is different, as is the Week/Year even though they are all identicle sticks. I have tried old sticks in 1/2 and new sticks in 3/4 and it doesnt fix this issue. Does anyone have any ideas/ have had a similar problem?

Thanks

totally expected. Ryzen 2600 does not really like 4 moduls of ram. Typically 2400-2666Mhz seems to be the roof frequency for most.

 

A2B2 slots should be used, and 2 modules. 2x8GB, 3000+ Mhz.

 

Sell the sticks, get 2x8.

Life is really challenging. I don't always suceed: )

okay i understand that, it would be good to know what speeds my actual 4x4Gb is running at to know whether it is worth spending the $~30 diffference from selling my kit and buying a 2x8gb 3000mhz+
