[SOLVED] DDR5 1rx8 vs 1rx16 ?

[GarGouL]

Is it even worth buying 2x8gb Crucial DDR5 4800mhz CL 40 1rx16 for gaming?

Anyone owns a pair of these? I could buy 2x16gb with 1rx8, but I can't really afford it. Stuck with DDR5 motherboard.. So DDR4 is not an option.
How bad is 1rx16 when it comes to DDR5?

Must be pretty bad 😅

Can’t you return the motherboard? DDR5 seems a huge waste of money for gaming. I expect it’s going to be 1-2 years before it provides any useful benefit once it has matured and higher speed and lower latency becomes more common.

I have not seen any single channel vs dual reviews but if it’s like DDR4 it can be anything up to a 30% loss in performance and single channel can also suffer stuttering. I would not plan on adding RAM later as that’s not guaranteed to work, the RAM should be bought as a matched kit.

First good luck finding any DDR5 in stock.

Yes 4800 with 40 cas is just bad that is why most people are buying DDR4 boards it's in stock, lower priced, and still faster.

Thanks for the replies!
The bandwidth is 50% higher on DDR5 kits, which makes it difficult when theoretically trying to compare 1rx8 vs 1rx16.
1rx8 is in some cases 20% faster in some area with DDR4. But can this really be translated to DDR5?
Really hard to tell without testing this irl.

"Real" dual channel is better even with DDR5 it seems.
