DRAM yellow light problem

[Mussels]

Don't forget @Mussels that none K CPU have a locked SA (1v) and pretty much are useless for memory beyond the official supported spec by Intel.

good point.
You'd think Asus wouldnt list RAM speeds the non-locked CPU's couldnt achieve, but i've seen some shocking ones (DDR4 4400 on the QVL list, at 2133)

So a non-K is not only just minimally OC'able (through unorthodox methods, of course), but also can't really take advantage of XMP either?

But we're drifting, as OP's post was about Ryzen....

To a limited extent the current gen boards can, but they're definitely more restricted. AMD pushed them to unlock them a little in modern gen, i'll see what a budget DDR5 board is like

B760 GAMING X AX (rev. 1.x) Key Features | Motherboard - GIGABYTE Global

These guys say DDR5 7600, with only 4800 not being overclocked

They don't mention CPU limitations, but they have a ton of disclaimers
Four dual rank modules is only supported at 3600MT/s, of that 7600MT/s they want you to think it'll easily run.
They also vaguely state you need 'certain CPU's to go above 5000, but fail to mention any details (12/13th gen, K non K, etc)

They have RAM modules listed in a PDF file with "native" of 4800 and 5600, with no real logic as to what that even means
Why are the first two kits only 'native' at 4800 while the third is 5600? They're all single rank Hynix A 7600MT/s

In this case i'd say that documentation is worthless to a home user and only done in a way they can translate back to you later to pin any issues on the user for going above "native" into "OC"

All very interesting. Makes me wonder if certain Ryzens / supporting boards don't like certain DIMMs or can only use them without DOCP for similar reasons...

Yeah, AMD at least published supported RAM speeds for the 5800x3D and onwards - and sometimes they've updated the older CPU's but its' a bit erratic.
AMD Ryzen™ 7 5800X3D | AMD

1st and 3rd gen ryzen had the biggest changes, this is a slide fron zen1 launch

Yet people will see a board that claims DDR4 4400 (with a 5700G, two ranks and extreme effort) and try to get that running on a CPU that only supports 1866 with 8 ranks.
It's maddening, and websites like gigabytes do nothing to alleviate that confusion.


I feel like 99.9% of PC users have no idea what memory ranks even are, yet they're critical to supported speeds.
because a youtuber runs DDR4 3600, everyone wants DDR4 3600 - even with 4x dual rank sticks (8 ranks total) on a $100 board vs that youtubers $1,000 board, and wonder why it crashes all the time
In this case you can raise the SoC voltage, and thats what the premium boards simply do - they run higher SoC voltages or have better power delivery keeping it more stable.

As ir_cow said above, intel just bin that per CPU series - non-K? SA voltage (their equivalent to SoC) has a hard lock at 1.0v so not even the board makers can help with their compatibility.



Edit: i went and found one of aorus latest AM4 boards, so i could see how it lines up with the information above.
X570S AORUS MASTER (rev. 1.0) Key Features | Motherboard - GIGABYTE Global

DDR4 5400?? ON AM4?

Using LN2 someone reached 6,666MT/s but claiming 5400 as a supported speed is utter crap.

They have a downloadable PDF for each CPU series by codename, which is usable but not helpful to beginners.

They actually claim you can run these speeds on vermeer, the 5000 series ryzens that are well known to not even reach 4000 stable.
There is DDR4 5100 ram QVL'd to 'just work' on this board.

Oh but they cover themselves legally with this

It's no wonder people have nightmare with memory compatibility. Hulk smash.
Needing to download a PDF file to scroll to the very end to see one line of text, is not how you advertise actual support. Why not just say "supports DDR4 3200, and overclocking"

 

[felipe.carv]

The exact same problems exist on intel as well.
*EVERY* generation of CPU has a maximum speed to it's RAM support

The difference is that budget intel platforms BIOS used to lock you so you can't even try higher speeds while AMD allowed you to try overclocking to get it working.
This led to "why work on intel, but not AMD" problems a lot (because intel locked the speed slower)



As for Intels modern RAM support, it's chaotic AF.
Board makers claim speeds higher than the CPU can support, intel changes to 'gear 2' for better compatibility at the cost of losing performance instead of gaining it.

Random pick from google here - asus B760 (Ended up being DDR4)

DDR4 3400 and above are listed as "OC" with only 3200 and below guaranteed on 13th gen. That's key here, as automatic settings may not work.

The RAM speeds supported vary for every CPU type (each generation, K and non K)
According to Asus, a 12th gen non-K CPU Can run DDR4 5133 RAM at 5066, while a 13th gen can only do 4400

Get a 13th gen K and it can do 5333

wow, didn't know that.
always saw people complaining about AMD, even the GPUs.
Just gotta do a better study next time I upgraded, I guess haha
Im just sad that now I have the two old RAM sticks not getting used. Maybe I give them to my brother

Waste not, want not.

However, he might want to check his board's QVL before installing them. And it's not wise to mix DIMMs of different SKUs (part #) either. Food for thought, I found out that not only were the DIMMs I originally used on my Ryzens not listed on QVL, the only person I could find that ever remembered using them said they were pretty sure they were optimized for Intel, as he had used them on a Coffee Lake build (two Intel generations before my Ryzen, if memory serves).

AMD is great when it's right. But they do seem to be a bit fussy, and when not everything is just so, it's a bit like trying to run a Lamborghini V12 on 87 octane. It's not going to be happy.

On another note, OP, what are your thermals now that everything's back together?

CPU not over 60°C, but I didn't playing any games lately, but gonna keep looking still.

You can likely use the RAM, you just need to use it at speeds supported on the hardware and manually set voltages, including the memory controller.

Mixed RAM can always be made to work - just no guarantees at what speed
