Ryzen 5000 Memory Performance Guide: 2 vs. 4 RAM Sticks

Dammit... there's no review buffered ram aka ECC

I used to have 4 sticks of 2 gig ddr3. They had a similar article years ago. Although I was probably GPU bound ^^.

Dammit... there's no review buffered ram aka ECC

Buffered RAM and ECC RAM are two different things: buffering just adds an extra DRAM chip onto the DIMM, to hold data before transferring it. This is required for when the memory system's electrical load is very high (I.e. every memory controller loaded to the hilt with lots of high capacity DIMMs), as provides a bit of a 'breather' for it all - the end result is a slower, but more stable memory system.

Buffered RAM also requires the motherboard to have the necessary support for it. ECC also requires additional circuitry but on the DIMM itself, but it just detects and corrects bit errors. You can get buffered and non-buffered ECC DRAM.

No Ryzen processor has support for buffered DRAM but they do for ECC - however, it requires the motherboard vendors to validate it, which none do for their consumer-grade products, as far as I'm aware (could well be wrong, though!).

Can anyone help me please? Is it better for performance to buy 4x8 GB 3600Mhz CL16 RAM or 2x16 GB 3600 MHz CL16 RAM for Ryzen 5600X on MSI X570 Tomahawk and RTX 3080 Gaming X Trio? (G.Skill TridentZ Neo)

The scales for graphs in this article are all over the place. Most graphs start with the X axis on 0, but some of them start at arbitrary values, such as the Shadow of Tomb Raider 1440p graph and AIDA64 Engineer Memory Copy one. In the latter, the 54.6 nanoseconds of 3800 MHz RAM looks much better than the 57.1 nanoseconds of 3600 MHz RAM, even though the improvement was only of a few percent. You can't do a switcheroo like this, it confuses the reader and is basic "don't do this or your graphs will be misleading" stuff.

Don't over think it. Today's 16GB sticks are mostly dual rank so stick with 2 of those to be safe. A lot depends on individual motherboards and other factors like the article says...then yes you can upgrade later if desired and you will get either dual rank or quad rank but it still won't be quad channel.

Ended up getting 2x16GB dual rank 3600 CL16 G.Skill NEOs (supposedly Hynix C Die from some research online). It was the ideal option even from a physical standpoint. The X63 Kraken pump was quite close to the slots and it would have been pretty tight with 4 sticks.

I'm yet to get the sticks to run at 3600 but there are some BIOS issues with the x570 board and Ryzen 5600x CPU. I'll have to wait for the stable updates.

Thanks for you help.

People here seem to be suggest that 2x16GB dual rank is the way to go as some motherboards may have issues with the 4x8GB single rank ones. I'm running the MSI X570 Tomahawk Wifi with Ryzen 5600x and 2x16 3600 CL 16 G.Skill TridenZ Neo and all seems OK. Though I've not yet bumped it up to the full 3600 due to lack of BIOS support until new firmware arrives...

"For much of this testing we used G.Skill’s TridentZ 3600 CL14 memory which we manually tuned, raising the CL to 16, but aggressively tightening the secondary and tertiary timings which massively improves performance for all Ryzen processors. This configuration will be tested at DDR4-4000, 3800, 3600, and an underclocked 3000 config."

I have a 5900X, RTX 3090 and the TridenZ 3600 CL14 you tested with, can you share the specific memory timing config you used?

Any updates on this? Have you been able to run them at 3600mhz spd now?
Also are your kit the Neo's with default cl 16-19-19 timings?

Using the beta Bios I managed to get it to run just by enabling XMP. Yes, those timings are as you say.

not really there are single rank x2 16gb kits, I have one

Sure there are but most are dual rank as stated in my post you quoted. By the way what brand/model do you have, just curious.
