about unstable RAM

[ˢᵈˣ FatCat]

long time ago my PC infested with Freeze Screen then black screen, Some of guys telling me to lower the RAM , so i did 3200 to 2666mhz, all works fine
but my curiousity want to know why my Motherboard/CPU cant handle 3200mhz which 5600x +b550f supposedly can handle 3200mhz easily, and only some of game, entire my games only Wuthering waves, and occasionally deadlock , but i guess that game is till in BETA,
then Stalker 2 when my PC using 3200mhz it will be crash

SO, the questions are : how do i can get 3200mhz with stable do i need buy better Cooling for my CPU? i doubt that, because my CPU tdp 65watt, and i observed my Temp wont exceed 65, 70 for frostpunk 2
IF i buy series X Motherboard, can i handle 3200mhz and beyond?
and why some games are prone to crash than other when doing 3200mhz, was that the game fault?

Well, first of all the ram should be a kit. Second, you should try with the xmp profile and not just setting the megahertz to 3200.

The BIOS may need to be updated also for compatibility purposes. There's also a qvl of tested ram, for guaranteed compatibility.

For reference I have a computer with a 3300x processor and it does xmp 3200 with four dimms installed, so the 5600x should be able.

silicon lottery

cpus imc has more trouble running 4 dimms at higher freq

check cpuz, spd/xmp profiles for 3000-2800 and see if it can run at those with slightly lower timings than its 3200 profile for similar performance

when iam using XMP/DOCP, it even worse, one time i just crash when i was alt-tabing , but that was 3200mhz, which if i do Auto or set Frequency to 3200mhz , it relativly stable till it's not when playing those specific games, 2666mhz 100% stable,

SO next up : DOCP still on but lower frequency? ill try after i have a good night sleep, been looking entire youtube and stuff, made me believe that 3200mhz is just hit or miss for Ryzen

How many sticks you have?
Are they exactly the same model/manufacturer?

If you have mixed sticks, then it's not even worth trying. Just go with default.

I'm running 4 sticks (4x8GB) with 2993MHz on Ryzen 5600 and B450. With 3000MHz it gets errors. All 4 sticks are exactly the same model.

Running games is not a good test for memory. I can run games and browse internet quite long time on 3000MHz without errors, but Memtest86 shows errors quite quick.

You really need to run memtest86 after every change of ram config.

It's better to set XMP and then lower frequency. XMP sets also voltage and timings to the tested value.

Timings are at least the same important for performance as frequency.

2 the usual dual channel, on 2 and 4 slot

I mean memtest like 8 hours for 32gigs, but if things have to do that way i dont mind
Corsair cmh32gx4m2z3200c16,
I heard chip from samsung are bad

So docp on , frequency low, you got it thx man, ill try it later

[_I_]

try enabling xmp/docp 3200, then bring the speed/freq down to 3000/1500mhz
should keep the timings and voltage for its profile but use slighly lower speed
and see if thats stable

I find it really strange that you can't get 3200 working. That's pretty much a guaranteed frequency from amds webpage.

You need to list your complete specs because something isn't right. I even got 3200 working on my little ryzen 1200af (4 dimms even).

R5 5600x
B550f strix
32gigs 3200mhz
Seasonic prime Gx-850
Bios updated
Chipset updated
6800xt strix
It was not completely doesnt work, but for some game it will crash, thus i say unstable

There is no way it might be my GPU, tested on 3 different pc shop, even Asus center are fine
CPU, Motherboard, RAM brand new after RMAed lol
So except iam unlucky twice getting the same defective, i make a peace that i cant do 3200
Oh and PSU is fine too, the says

[_I_]

try one dimm at a time, see if one is better than the other, then the other channel (slot 2 or 4)

[Illusion of Progress]

RAM is harder is stabilize as the following increase...

DIMM count
Rank count
Frequency

And the CPU, motherboard, BIOS version, and particular RAM itself are all factors as well.

That being said, on Zen 2 or 3 CPU (3000 and 5000 series as they have the same I/O die), and on a 500 series motherboard with a recent update BIOS... I really would expect that 3,600 MHz or at least 3,200 would be "almost always stable", even if you're using four DIMMs. The earlier Ryzens with earlier motherboards and their BIOS had more of a trouble with then-high speeds, especially with four DIMMs, but later ones were much better off.

I had that exact motherboard (actually still have it as a return from RMA but it's unused), and it ran four DIMMs, dual rank even, at 3,600 MHz. That was with both a 3700X and a 5800X3D. However, I did have some rare one off (or two off) issues and I'm not sure if the RAM configuration wasn't at fault. I had this strange issue with some older BIOS versions (basically, the system would play Russian roulette on if it would spontaneously restart after loading into Windows, but ONLY right after loading into Windows, and ONLY on certain BIOS versions). Eventually, I also had spontaneously restarts occurring on BIOS other than the known ones to cause it, and during use, and the DRAM LED would be lit during this time. I then had an issue when every cold boot would fail POST on the first attempt and then succeed right after. Around the time I was beginning to look into those issues, I noticed I had a failed M2 port so I just did an RMA and bought a new motherboard (different model). I haven't had any issues like that since. The ROG Strix B550-F is supposed to be a very, very good board but I wonder if its RAM handling isn't quite as good. Or maybe mine was just bad in that regard.

Does all of your RAM match?

What RAM is it? I know Corsair Vengeance LPX had infamous issues with Ryzen in the past, but I'm fairly sure those are more or less in the past now and shouldn't be a thing anymore. Figured I'd ask anyway. Given the choice, Vengeance wouldn't be my first pick for a Ryzen though, especially the lower end LPX variety. I heard stories of people getting matched kits that were actually different RAM with different ICs/dies.

Silicon lottery does ultimately exist. AMD only guarantees lower speeds when four DIMMs are used. If you've found that lowering RAM speeds helps bring stability, then it's sort of a strong indicator that it's not stable at higher speeds. I wonder if the RAM or one of the CPU voltages isn't being auto set high enough to be stable at the higher RAM speed, or if maybe the motherboard might be auto assigning less stable sub-timings for the higher speed.

THIS seem same happened on my board before i RMA, just bootup then no signal , then i said wait a minute this isnt normal, then i bring it to ASUS

I dont think the motherboard was the weakest link more like the CPU,
I saw at reddit, a guy just like me jad same problem ,with same pc except they have 3080ti,and 5900x Ryzen and the problem gone, just like that

But buying that CPU meaning i should buy AIO too, and i need buy new case too because fractal design 7 compact is too small, could but 240 one buy bad investment

And then of course Corsair, within all PC parts maybe this actually i never really care about nook and cranny, i just see oh this RAM is cheap, and 32gigs, that should ve be fine
Hell even my pc before this using random RAM 2 corsair and 1 Vgen, never crash yes it was only i think 1333mhz but i had happy life gaming

Damn it i need go to sleep, btw thx i will do the XMP with lower frequency

This is myth and it is absolutely not correct. This is why people get into troubles, setting ram speeds incorrectly, not testing and having random reboots/bsod.

The ram speed depends on the processor, ram sticks, the number of them and the motherboard. The best thing to do is read manual from motherboard manufacturer. Often there is info about which ram works with what speed with wich processor with what configuration.

XMP speeds are NOT guaranteed.

In my case the same ram stics worked faster when I had 2 of them. I had to slow them down after mounting 4. They run again faster after I changed the processor (from 3400G to 3600).
In all 3 situations different speed.

[_I_]

qvl is pointless too, too many board and ram combos for them to test

3000-3200 should work on almost all systems
some cpus have trouble, no matter what you do, that the silicon lottery

the board makes little to no difference, same with ram from its qvl

So docp on , frequency low, you got it thx man, ill try it later

Depends on the "Ver". From Corsair forums - The known and possible version numbers are as follows;

If it's Samsung B-die or Micron Rev B or E you should be able to go higher than XMP with 2x16gb.

that is why i think my CPU cant handle 3200, or i dont know, from now still no crash using XMP but 3000mhz
