Amount of memory going into my build

[EAGLE12426]

Hello and "Happy New Year to everyone on here!!" Can anyone tell me or explain to me is it necessary for me to have a total of 128 GB of DIMM's? My motherboard can support it and my CPU (AMD RYZEN 9 5950X), can also support it, if that matters at all to my question. The reason I'm asking is I'm having a hard time finding the low profile type memory, for that amount. It seams that I'm only finding up to 64 GB of it. Also, since it's going to be a workstation I'm getting "ECC UNBUFFERED MEMORY" to protect the data. Thank you in advance for your help and be safe!

A workstation build should definitely try to fill in all 128GiB, if possible.

I read this as 32GB and up.

It depends on your tasks… Do you need 128GB?

YEA, THAT'S WHAT I WAS THINKING ALSO! LOL! Thank you for confirming my thoughts on that. Now all I have to do is find them with everything being tied up. LOL! Again thank you my my dear!

 

[Komshija]

It depends what are you going to do with this machine. IMO 32 GB RAM is minimum for a decent workstation, 64 GB very good, 128 GB excellent.

 

[EAGLE12426]

Andy, with everything I'm going to be doing, yes 128 GB, the max my MOBO can hold.
Claes, I'm going to be doing, without going into detail, serious calculating.

That's why the need for ECC and my MOBO uses UNBUFFERED. THANKS AGAIN!

 

[Shrek]

If your 'serious calculating' needs 128GB, then you need 128GB

There's the Micron/Crucial VLP 32GB DDR4-2666, model number MTA18ADF4G72AZ-2G6B2, and not much more (if any). You give up a lot of speed by going from normal height to low profile.
Have you done any calculations about how much memory you need? 128 GB might be too much ... but it might also be too little.

Yeah load it up, read your board manual for clock speed you can run, get a 128GB kit, dont try to mix 2 kits together.

 

[EAGLE12426]

Sorry about that everyone had to go eat supper. Have to keep my brain trauma and strokes in check, no use in complaining about it. OK....I did check on the MOBO'S site..GIGABYTE, I can use up to 3200 MHZ speed on the DIMMS. I was trying to get 32 GB for each stick but, OUT OF STOCK in the DDR4. Also if anyone took my reply's wrong, I was just trying to explain what I had said. There are times my brain does not work the way it should like before I got injured, so if I had sounded like I was in left field that's why. On other sites I had visited I had explained this but apparently I did not on this one. With that being said: "IT IS WHAT IT IS WITH ME!!"

Manual/QVL says max 64 and 2666 but I’m sure it will take 3200. If you go for a 128GB at anything more than that make sure you can return it.

128GB ram overclocked?

OH OK, sorry again my brain did not understand what you had said. So let me get it, please tell me if I'm wrong Are you saying I should only use 64 GB at 2600 MHZ speed? Is that what you meant?

128GB ram overclocked?

This reply is for eveyone responding to my post. NO just ECC unbuffered 128 GB I had checked with Gigabyte TECH Support they said I can go with the 128 GB and use 3200 MHZ speed. But nothing over that speed. I was trying to get the most out of everything, DIMMS, GPU, CPU, M.2, etc. NO OVERCLOCKING on anything, unless it's absolutely necessary, of which it shouldn't be. Thank you everyone

Any reason not going with threadripper. 256GB

 

[EAGLE12426]

Any reason not going with threadripper. 256GB

Yes, because I already have a Ryzen 9 5950X, along with the motherboard that I have. On top of that, if I did get a threadripper CPU, and the mobo to go with it. NOTE: at the time I was getting parts and even now the cost of that is over 2. So I'm better off sticking with what I already have for the build. Thank you for the suggestion anyway.

Sorry I just looked at what I wrote, I would have to get the threadripper cpu and the mobo to go with it. thanks again

Everyone I know this isn't about my post but I need to take a break, sign out, because of my head, bad headache from the injury, sorry but this is what happens. I'll get on tomorrow and look at any reply's. Thank you everyone for your help and input, have a great night and please be safe.

Officially AMD does not support ECC on desktop CPUs. This also means MB vendors can choose not to enable it either. Also since you are prioritizing size instead of speed, you could get away with 2133 memory for a bit cheaper. Either way it looks like you'll be drop $400 for 128GB.

Yes they do, at least on GB X570 Master. The numbers I gave a few post above is from the QVL. There are four sets tested meaning that there are a lot more.

Hmm conflicting reports from AMD itself. They say no official ECC support on Ryzen. Its up the MB vendor. I also see Vermeer has official support on forums but no press release from AMD on the subject. Either way, Its not like the ECC is disabled on the CPU like Intel, just comes down the MB Vendor to validate it.

I would just go on ebay and pick up 2133 for cheap. No reason to drop $$$$ ECC memory.

 

[Ruru]

It's up to the motherboard manufacturer to enable the support for ECC if I'm not mistaken.

 

[Tetras]

The only ecc unbuffered vlp of that capacity I know of is Micron, which was already mentioned above. How much clearance do you need around the socket? One possibility I can think of, is to buy low profile, lesser capacity for the first pair (if you need cooler clearance) and then higher capacity 32GB regular modules for slot 2 and 4, giving you 96GB, but I'm not sure if that would widen your choice of modules much and could have compatibility issues. ECC unbuffered is probably the rarest type of module, I think Hynix, Kingston and Samsung are all available VLP @ 32GB if it's buffered.

 

[Wirko]

That Micron VLP is also expensive at over 200 dollars (or Euros).

Good evening to everyone on here. Sorry about last night and me leaving so abruptly. Since I have brain trauma It gets to me after awhile. WOW!! all the replies. I'll try to answer them since I left early last night. OK...Looking through them the mobo MFG whom I already talked to from there TECH Support said YES it can take ECC but, they were very strong about that it "MUST" be unbuffered ONLY for the mobo to accept it. Also the XMP, I think I said that correctly, I can enable it. Now as far as the speed of them, they, TECH SUPPORT, told me it can't be any faster than 3200 MHZ for the DIMMS. You are correct about the price for each stick. They go for between 218-243 each, depending upon the GB amount. 16 vs 32 per stick. Again I did not mean in anyway shape or form to cause such a problem on here. If I did or offended ANYONE at all or caused conflict between friends on here it was not my intent. If I did my sincere apologize. That goes to the owners of this site also. I just ask questions to get the best build that I can with what i got and will get. Thanks to everyone for your help. Hopefully I don't get booted or band from here because this is a very informative site. Even when I don't have a question I still look at other post and I'll put it to use when I start building it. Thanks again.

OH yes that is why I chose the X570 Aorus Master. It can be used for a workstation. I was going to get the next higher up one but at the time it was 800-900 just for it. Wanted to clear that up

Sorry I keep for getting to answer replies. The clearance is because of the CPU cooler. I had received a pic from the MFG with how close the DIMMS are to it. By what they sent me it's close, around 1/16th-1/8th, it might even be closer. I chose that cooler because of the airflow it can push with the two 140 fans it has on it. But I'm also getting DELTA FANS for the case. YES I know there a bit loud but, they have excellent airflow, the best you can get from what I've seen. No I don't want to go with radiators. I hope I answered all the replies so far to my post. Again THANK YOU ALL!!

Directly from the motherboards MFG Tech Support, it MUST be unbuffered that's a must. Also, I'm not sure but, I don't think you can "MIX SIZES". Even if I could, which I doubt, I would not be willing to even try. Just for the possibility of something going wrong. Thanks anyway for your suggestion.

If you have time, can you run your 'calculations' on what you have now and look how much RAM is being used? (Speccy should be all you need)
