Is 32GB DDR5 Needed on Intel 12th Gen?

I was wondering, given that all the DDR5 kits I have seen are 32GB, does Intel 12th Gen work better with or need 32GB of DDR5?

I have googled and searched forums but can not find any answer either way.

Anyone have any information on this or used 16GB DDR5 kits?
 
My take is that no, it is not necessary and 8GB DDR5 modules are available at most stores. But, if someone is penny pinching (so to speak), then they're just going to buy DDR4, which is half the price.

Thought there was no technical reason, other than possible pushing th higher priced kits.

Saw, on a Well-Know Global Online Store, they had Kingston Fury Beast 16GB DDR5 kits 6000Mhz, for £149.99, and it got me thinking, as more people would consider DDR5 if there were more 16GB kits.

I'm pretty sure there's not a technical reason, I haven't seen any videos or articles either, but 8GB modules are on the QVL of all the DDR5 motherboards I've looked at, so there's clearly no fundamental incompatibility there.

They are single sided, but so are the 16GB modules. The only caveat I can think of is that 8GB DDR5 modules have fewer memory chips than older DDR4 (only 4) and with high density DDR4 there is a performance loss with these modules. I'd like to see it tested.

Linus tested it with DDR4 and buildzoid talked about it too, but I can't remember which video, might have been this one:

Thank you for the information so some technical reason but same as when choosing DDR4.

Buildzoid has come out and said that getting DDR5 with low chiplet density (16gigs) negates the whole point of the technology because memory bandwidth is needed with the higher latency.

He has also said that slower DDR5 kits aren't good enough either because they are pretty poor quality.

That being said, if I wanted to move into the DDR5 world without breaking the bank right now with the aim to get a better DDR5 kit later down the road when the technology improves and prices drop, sure. That does make sense in my mind.

RAM doesn't impact your systems performance nearly as much as just buying a better GPU or CPU. I'm a complete hypocrite as I've got 4 Samsung B Die kits and one Micron Rev E. I like to play. I have realised that my 3300X and X570 Tomahawk are absolute potatoes at RAM overclocking but hey.

I would be super happy to move to a 2 DIMM slot Z690 motherboard because you don't need more than 2 DIMM slots for DDR5 and it also improves your memory overclocking ability.

Something something Z690 Tachyon can do XMP 7000 MT/s in their supported memory list something something and can do 8000+ MT/s.

THAT being said, the next gen motherboards and RAM will be much better quality (think first gen Ryzen versus second)

Ooh, did he do any testing? Would be super interested to see this.
 
Sounds like better to stick with DDR4 for the moment and move to DDR5 in 2-3 years once the quality is improved and the issues, like XMP not enabling or causing No POSTs, are sorted out/

Pretty much.

I really like the 12400F with a decent entry level motherboard and 32 gigs of that patriot ram for £99.

The only reason why I’m not going to buy it is because I have an X570 system already and the 5700X is a cheaper overall purchase.

Go price a high end kit of DDR5 ram. Stupidly expensive.

DDR5 is stupidly expensive, especially with all the problems its having, and its not encouraging people to adopt it.
 
16gb is a good option if you want a cheaper kit to hold you over for a year or two till the higher speed kits arrive and prices fall.

I think 32GB is already the new norm for new systems. With 16GB you won't be able to have much open in the background while gaming.

What are you opening!?

Like I’ll have 4 chrome tabs and I’m still fine with PUBG and 16gigs of ram.

The only reason I have a 32gig ram kit is because it’s dual rank and that improve performance (it is actually dual rank as per CPU-z.)

I can understand getting a cheap 16gig DDR5 kit now if you have to have it as it will be fine for gaming and some light video editing.

DDR5 is really going to shine with 4K and 8K video editing though - large capacities and high throughput.
