Highest RAM capability?

[adamnodder]

Anybody know what the highest ram capability is on a ASUS® PRIME B550-PLUS?

Tech specs show this...

AMD Ryzen™ 5000 Series/ 3000 Series Desktop Processors
4 x DIMM, Max. 128GB, DDR4 4600(O.C)/4400(O.C)/4266(O.C.)/4133(O.C.)/4000(O.C.)/3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3333(O.C.)/3200/3000/2800/2666/2400/2133 MHz ECC and non-ECC, Un-buffered Memory *

Does that mean i can use DDR4 4600? Not sure what O.C means?

Probably a stupid question so apologies.

Speeds need to match your useage, higher doesn’t necessarily mean better.

What are you using it for?

For gaming... I currently have x2 8GB 3200Mhz.

Was thinking of upgrading to x2 16GB (Whatever highest speed my motherboard is compatible with)?

I've been told the games I play are very RAM heavy and bottlenecking my system.

here is my spec...

Case
CORSAIR 4000D AIRFLOW TEMPERED GLASS GAMING CASE
Processor (CPU)
AMD Ryzen 5 5600X Six Core CPU (3.7GHz-4.6GHz/35MB CACHE/AM4)
Motherboard
ASUS® PRIME B550-PLUS (DDR4, USB 3.2, 6Gb/s) - ARGB Ready!
Memory (RAM)
16GB Corsair VENGEANCE RGB PRO DDR4 3200MHz (2 x 8GB)
Graphics Card
6GB ASUS DUAL GEFORCE RTX 2060 - HDMI, DP, DVI (Just changed to 4060ti)
1st M.2 SSD Drive
1TB INTEL® 670p M.2 NVMe PCIe SSD (up to 3500MB/sR | 2500MB/sW) (Replaced with a Crucial P5 plus 1TB)
NOT REQUIRED
DVD/BLU-RAY Drive
NOT REQUIRED
Power Supply
CORSAIR 750W RMx SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET
Power Cable
1 x 1 Metre UK Power Cable (Kettle Lead)
Processor Cooling

For gaming, 3600MHz is the highest you need, 3200MHz is the best value vs performance. No benefit to anything higher.

32Gb is the default nowadays for gaming and you should always have matched pairs as it's dual channel RAM.

As above, DO NOT just buy additional RAM sticks, replace the whole lot with a matched set. I see many BSODs caused by mismatched RAM. Even if the additional sticks are the same part number there can still be minor differences that can cause BSODs.

I was going to replace the x2 8GB 3200mzh to x2 16gb 3600mzh.

Is it worth doing will i notice much difference?

Speed-wise probably not, but capacity wise, as @SpyderTracks has said, you might...

Before you spend money however, I can tell you whether you have a RAM problem. Open Task Manager, click the Performance tab, then click the Memory icon on the left. Then click the Options tab and select the 'Always On Top' setting. This will obscure your game of course but for now you can live with that. You can shrink the window as small as you can - but I MUST be able to see all the numbers at the bottom.

Now fire up the game you think is RAM hungry. Take a photograph of that window when you suspect the game may be bottle necked, or several photographs at various times during the game, or even take a video of that Task Manager window as you play - as long as we can clearly see those numbers. If you play more than one game then repeat this for every game you think may be RAM bottle necked

To be clear: It's VITAL that I can see the numbers at the bottom of that Task Manager display and I want to see them most when you think the game is RAM bottle-necked
