About my Gigabyte B550M DS3H motherboard (version 1.2)...

[Kerozen1973]

I can't install more than 32gb of ram while yet I can put up to 128gb. On this card there are 4 slots for the ram. So I think my card has a problem. Are you going to tell me why I want to install 128 GB of RAM? And I answer you then that it concerns me and it is not your onions.

Your problem is with compatibility. AMD is rather picky on compatibility and speed. You must refer to this list: https://download.gigabyte.com/FileList/Memory/mb_memory_am4_4L4D_matisse.pdf

I found this list here: https://www.gigabyte.com/Motherboard/B550M-DS3H-rev-15/support#support-doc

That is the compatibility list for your motherboard.

I can see in this list that there are some ram kits rated for 32GB that can be installed in all 4 slots in your board. But you may have to run at a significantly reduced ram speed. Like 2133 Mhz or 2400 Mhz. You will not be able to run ram high speed (3000 Mhz or faster) with 128GB of ram in that system. You also must have a 5000 series AMD processor in there to use that configuration as well.

Ah okay, thank you. I understand. Then I'm staying with my 32gb.

My motherboard is well priced and is current and well rated by users. However, I think there must be better in B550M mini Atx format and at a good price also with wifi standard wifi 6? My current motherboard has took static electricity.

I wanted to add additional first-hand information for you. I own an AMD X570 motherboard and I have an AMD Ryzen 5800X processor in it. I too like you would like to use 128GB of ram in my motherboard. My motherboard says it supports it. I attempted to purchase 4 x 32GB memory modules rated for 4000 Mhz, which in theory should operate at any speed this motherboard and processor is capable of. I have many years experience configuring ram and it's timings and speeds manually. I spent much time with this memory configuration (3 weeks) attempting to get it functioning. I worked on it with all of my free time every day for 3 weeks. Eventually after all of that time the maximum speed I was able to achieve that was stable without errors was 2600 Mhz.

I spoke with other people about this issue on other forum websites (overclock.net, Techpowerup forums, Linus tech tips forums) after some back and forth with others I realized that this is a limitation of AMD's AM4 platform in general. All AMD AM4 processors are not able to run faster than 2400 <-> 2600 Mhz on memory when using 128GB of ram in an AM4 system.

I returned that memory kit to Newegg claiming it wasn't compatible with my system.

I instead returned to my old 2 x 16GB (32GB) kit and it has been functioning normally at 3866 Mhz for several months now without issue. It is not the capacity that I want but the performance is significantly higher than with the 128GB kit. For me the performance is more important. I will later wait and upgrade to a computer that supports DDR5 to be able to run 128GB of ram at higher ram speeds. DDR5 compatible systems are capable of running 128GB of ram at higher speeds (5000 Mhz or more).

I have the same motherboard gigabyte b550m ds3h. I have 96 GB of RAM and running it @ 3200mhz stock speed. Don't know why but when you further upgrade your ram the ram speed gets lowered to 2600mhz. Go into your bios and reset your ram speed to profile 1 that should fix it.

4 x DDR4 DIMM sockets supporting up to 128 GB (32 GB single DIMM capacity) of system memory

max per dimm is 32g

4 dimms is more work on the cpus imc, it may not hit higher speeds with 3-4 dimms vs 1-2

Out of topic sorry but we have the same motherboard. Does urs have led headers? My led headers are missing i think

[Phénomènes Mystiques]

I would use 128GB RAM for intensive game designing, video and music creation.

If you actually need 64-128GB of RAM, then do yourself a favor and buy a full size ATX Motherboard that is actually decent quality overall. MicroATX boards are all junk for this and is why most of them fall way short should you wish to use all 4x DIMM slots.

Yes micro ATX motherboards do have limitations. I also have a micro ATX motherboard and using all 4 ram slots, at the stock speed of 3200 MHz, currently seeing no problems. I just had to change ram speed back to 3200 MHz because when I put more ram in it defaulted back to 2600 MHz.

Is it a RAM kit of 4? What do onions have to do with it? You mean opinions? Everyone has a right to their opinion.

If your RAM isn't in a kit of 4 dimms then that's probably why you're unstable.

Doesn't need to be a 4X RAM kit. They just need to have the same specs and support the same settings when XMP is applied.

This is all getting kind of off topic. I think this thread has been answered already.

Not everyone cares what you think.
