About my ram

[Dont forget me]

Hello,

I have a Gigabyte AMD AM4 B550M DS3H and a Ryzen 7 3700X and my power supply is a 550W.
I would to raise up my ram for 64go but I can't put more than 32go if not my game like DCS crashes and I return to the desktop windows.
The manual of my mother board tells I can raise up until 128go but what is the condition? I have already tried with 1 kit of RAM compatible with my motherboard and they have not been good. So, I don't know what to do.
Can you help me please? I don't want to put 128 go but 64go only but they are not good too. What is the issue with my ram? Is it working with my CPU and my GPU maybe? Or maybe my power supply is not enough strong?

Not possible, the default is Disabled, there is no auto option on the B550M-DS3H or pretty much any board.

There's Disabled, Profile 1, and also Profile 2 if there's more than one available profile saved to the RAM by the manufacturer.

No. The default is auto !!! I know my computer but I don't know why it crashes in game only ??? with 64go of RAM.

Clearly you don't know your own system, the manual for your motherboard says otherwise and XMP/DOCP and EXPO are disabled by default.

If you're mixing RAM then XMP doesn't work.

you could do like me and have multiple computers, with one handling the low ram games and the other handling the games that can handle high ram. though most games does not have issues with high amounts of ram. another possibility is to use an app that reduce your ram. another alternative is to change the ram based on tasks by taking sticks in and out. though there is another option and that is to multiboot windows with one 32 bit version and one 64 bit version. 32 bit windows can only use 4 gigabytes anyway.

The only way to know if your RAM causes problems/crashes is to run memory test.
If you run Memtest86 and you don't see errors them RAM is not causing problems (but something else).
If you run Memtest and you see errors, you need to change RAM settings in BIOS/UEFI.
There is nobody here or anywhere, who can tell you why your PC is crashing without testing. There are many people here and in other forums who will tell you what do change/buy/install even without reading what your problem is.

There shouldn't be any instances where a 3700X needs 64GB+ RAM, 32GB is more than enough, in instances where that much RAM is going to be required, that CPU is likely going to hold the system back anyway.

There's plenty of conditions that need a lot of RAM where a fast CPU isn't needed. I went into AM4 with a 3700X and 64 GB of RAM and ran out of RAM a number of times. In all of the times I did, I was never CPU limited.

Different tasks have different weightings in what they need more or less of. There is no balance rule of "you need x amount of CPU before being able to use Y amount of RAM or Z amount of GPU" with PCs. PCs and software do not work that way, even if there are general trends within certain subsets of software (like games) where that may "typically" be true.

I'd rather frame it as "if you have to ask if you need X amount of RAM, you probably don't".

And if you're framing this from the perspective of gaming, then I would agree with what you're saying (you just phrased it a bit wrong) by saying probably don't need 64 GB for that. As far as I am aware, when it comes to games, only edge cases (specific games, and typically modded) will use as much, and even then it's probably not a "need". A lot of people probably automatically think "needs more than 32 GB, so 64 GB is needed" but non-binary DIMMs exist now, so 48 GB will cover a lot of that, meaning there's even less where 64 GB+ is "needed".

The people with 64 GB+ either need it, are are enthusiats/gamers who have extra money to waste and want more than the typical amount to feel like it makes their PC better.

Tell me what I'm supposed to do for having 64go of RAM without having crashes in game ?

more ram only helps if you need more ram
too much only hurts if the cpu cant run it at higher speeds

My cpu is working 6 core and 12 thead 3,6ghz 65 watts
My actual RAM is 1 kit of 2 x 16go G.Skill 2400MT/s 1200mhz, 1.2 volt each

Nobody can guarantee that you will be able to buy a kit of RAM and have it operate at its profile speeds because RAM manufacturers can only guarantee that the KIT itself can do that. Whether your system can is another story. The CPU (and even silicon lottery comes into play), motherboard, and its BIOS all matter here.

AMD lists the guaranteed RAM speeds, and it depends on how many RAM DIMMs (and how many ranks) you use.

Your current RAM is 2400 MHz, which is slow for DDR4. Speeds of 3600 MHz "should" work, and 3200 MHz is more of a "should always" work while still being fast enough. More than 3600 MHz is a gamble on AM4 without dropping IF speeds. Speeds below 3200 MHz are too slow to bother with. In other words, go for 3200 MHz to 3600 MHz.

If you want to add new RAM and keep using your old RAM, the profiles may not play well (you're using 2400 MHz RAM and I imagine you tried adding much faster RAM before), and your old RAM is already slowing your system/CPU down. I'd recommend getting rid of the old RAM and going with a new kit of 3200 MHz or 3600 MHz RAM.

If you really have a Ryzen 7 3700X, it should not be 6 cores and 12 threads. Something is wrong. The 6 core and 12 thread version is the Ryzen 5 3600/3600X.

First, I learned that RAM power is not 3200 mhz but 3200 MT/s. About my setup I can't install more than 2 ram of 16go each ram = 2666 MT/s = 1333 Mhz. From 2 x 2666 MT/s my setup starts to be not stable.

There is a full support list published by Gigabyte for your motherboard:
https://download.gigabyte.com/FileList/Memory/mb_memory_am4_4L4D_matisse.pdf?v=c4e9aaa4651d9b2b345e190debda4e98
You have to look on AMD Matisse. Also check which revision of the motherboard you have because the link is to latest revision (1.7).

If you want 64GB RAM, choose the kit that is supported. You can have 4 sticks x 16GB, but again check which models are supported.
If your model is not on the list it means it has not been tested. It might still work, if you play around with settings, but you have to run the test after changing anything.

But its easy because when I have installed 64go of RAM, I must to remove 32go and I must to clear the CMOS because my pc crashes totally.

[Dont forget me]

Ok I must to buy 4 x 16go for having my 64go. Same kind of RAM.

[andreasaspenberg575]

that would be wise, yes.

[_I_]

ddr freq = ddr number/2
ddr 3200 = 1600 mhz

if its ram from the same kit, xmp/amp/docp/expo will set the freq, timings, voltage for the dimm/kit

You can, but you don't have to choose 4x 16 GB. If you can find 2x 32 GB, that's also an option, and I'd recommend that between the two if the price is around the same. The reason is because it's going to be easier to stabilize with less DIMMs (two DIMMs is easier than four DIMMs), which means the chance it will successfully run at the speed/timings you want it to is higher. Since you already had issues stabilizing your last RAM attempt, I imagine the better the chance of success, the better it is for you.

I have 4x 16 GB myself, and while that usually works fine on AM4 up to 3,600 MHz (the CPU's IMC and motherboard plus its BIOS permitting), I bought it in the middle of 2020 when 32 GB DIMMs didn't yet exist (or if they did, they were pretty new and weren't as commonly available). I imagine a lot of the DDR4 RAM that is 16 GB might still be older and thus still dual rank (?), so you're not doing yourself any favors to chose that over 2x 32 GB. And even if it's single rank, two dual rank DIMMs will be easier to stabilize than four single rank.

2x32 is better than 4x16 for stability
