Buffered / Registered memory

Alright that clears things.

Yes

Anything over 16 isn't. Then it comes down to latency really. 

Having a bit of headroom also helps for multi tasking and video rendering.

 

 

Alright I think I get it now, Registered = Buffered and Unregistered = Un-buffered. and Buffered will never work on Un-buffered Motherboards

 

Thanks.

Hello, I just want a little clarification about ECC Memories since the browsing the web about ECC support on none server systems have conflicting points, and to gain knowledge to know whether the RAM I would buy would be just defective or incompatible in the event of it not booting/working.

 

I have this budget system:

CPU: Ryzen 3 2200G

MOBO: Asus EX-A320M Gaming

RAM: 8GB DDR4 2666MHz CL16 HyperX Fury (Had 16GB but I gave the other stick to my friend, yeah just had to mention that)

GPU: RX 580 4GB

 

Then I found some great deals on FB Marketplace:
1. A 32GB DDR4 single stick ECC memory for only approximately $40 converted from PHP

2. and a 32GB Kit 2x16GB for approximately $80 converted.

 

-------------------------

32GB RAM:

MICRON 32GB PC4-19200 DDR4-2400T-R REGISTERED ECC 2RX4 CL17 288 PIN 1.20V MEMORY MODULE ( PC4-2400T-R )

MANUFACTURER: MICRON
PART NUMBER: MTA36ASF4G72PZ-2G3B1IK
COMPONENT DENSITY: 32GB
PRODUCT BUS TYPE: PC4-19200
COMPONENT SPEED: DDR4-2400T-R
MODULE SIGNAL TYPE: REGISTERED
ERROR CORRECTION CODE ( ECC 😞 YES
COMPONENT RANK: 2RX4
CAS LATENCY: CL17
PIN COUNT: 288-PIN
VOLTAGE: 1.20V

-------------------------

16 GB RAM:

16GB 2Rx4 2G x 72-Bit PC4-2133 CL15 Registered w/Parity 288-Pin DIMM

MANUFACTURER: KINGSTON
PART NUMBER: KVR21R15D4/16
COMPONENT DENSITY: 16GB
COMPONENT SPEED: DDR4-2133
MODULE SIGNAL TYPE: REGISTERED
ERROR CORRECTION CODE ( ECC 😞 YES
CAS LATENCY: CL15
PIN COUNT: 288-PIN
VOLTAGE: 1.20V

-------------------------

 

Things I understand (I think I do) so far from browsing around:
- You cannot mix Unbuffered and Buffered

- Buffered/Registered memory has a register between the DRAM itself and Memory controller

- All Ryzen supports ECC unofficially, still depends to the board manufacturer, though but the ASUS site states that ECC Memory (ECC Mode) support varies by CPU. (I guess the board itself does support it?)

 

Things I'm uncertain about: (Actually, everything written in this forum post pls help)

- If the motherboard only supports un-buffered memory, will using a buffered memory run the ram as un-buffered and work just like a normal un-buffered RAM would or will it not post at all?

- Some motherboard that supports ECC do work with ECC RAM but does not use the ECC function.

- What is the difference of Buffered to Registered and Unbuffered to Unregistered? Some sources say they are the same, some make it seem they are different so idk anymore.

 

Some notes:

- My current RAM struggles on games like Rust and COD Warzone with Rust crashing to desktop from loading (used to work but stutters) and Warzone having immense stutters in-game (RAM being maxed out).

- I don't really care about ECC, I just want to know if it'll boot.

- I understand I'll lose a bit of FPS on going down from 2666MHz to 2400 or 2133 but I think it's too small that eliminating the stutters would be much more practical. (DDR3 vs DDR4 has very little difference in terms of gaming right??)

 

The overall question/s: Will it boot? Is it a good idea?

It won't work at all.

If it's only ecc. Like you said. Ryzen supports it unofficially but buffered will not work.

These are two completely different types and you can't really compare this to each other. But only ddr4 will work with am4.

You need UNBUFFERED memory. 

 

Buffered / Registered memory will not work because the AM4 processors don't support it. They're types of memory for servers. 

 

ECC ... that's error correction on memory stick. It's basically an extra memory chip on the sticks. 

 

The AM4 processors support ECC, the "Pro" versions of AM4 Ryzen processors even advertise this.  The non-pro versions also support ECC 

In the end, it depends on the motherboard (its bios) if the motherboard accepts ECC UNBUFFERED sticks. Some bioses will show memory error, some won't start at all, most should work.  

Even then, you may not get the benefit of ECC - the bios must implement support for ECC correctly to have that working. So you may be able to use ECC UNBUFFERED sticks, but with the ECC part basically unused/ignored, or that part may be fully working. 

 

You can't mix DDR3 and DDR4 , and socket AM4 supports only DDR4  - you can't put DDR3 sticks into DDR4 slots, you can't use DDR3 at all with socket AM4.

So, is Buffered = Registered and Unbuffered = Unregistered?

Both RAMs on their spec sheets mention ECC Registered but no mention regarding it being Buffered/Unbuffered

Yeah I know different DDR Generations have different keys and pin counts, and I only used that as a medium of comparison to different RAM Frequencies and their overall impact to gaming. I've always found that capacity is more important for gaming.

Woops sorry, my browser chrome (yeah chrome... might need that extra capacity after all) opens the link to a new tab and views the site via built-in PDF Viewer

Anything over 16 isn't. Then it comes down to latency really.
