DDR5 Ram Question

Hi,

I'm currently tweaking my specs to reign in the price before I hopefully order a new PC next month and one of the things I was going to do was to choose 16gb DDR5 Ram instead of 32gb as that's something I could always do in the future quite easily. However I noticed that at 5600 & 6000mhz, I can only choose a single stick option for 16gb rather than 2x8gb sticks.

I don't keep up with PC trends these days but in the past wasn't it the case that you would lose performance with 1 stick of memory instead of splitting it over 2 sticks?

Yes, that is correct.

Current recommendation for a DDR5 build is 32GB of RAM in 2x16GB config...and in some configurations the RAM speed when using 4x sticks can be worse than 2 sticks due to the memory controllers on the CPU.

The issue with adding more later is ensuring you fit IDENTICAL ram (not just the same specs, but the same part numbers, from the same manufacturer or throwing what you have away and starting from scratch.

Also, the performance loss from the slowest DDR5 to 6000MHz can be as much as 10% in some applications/games...and if you're considering an Intel build (don't) then be aware that some of their microcode changes may artificially limit memory timings to stabilise their CPUs.

Cheers for the feedback and i'm not doing an Intel build (AMD Ryzen always for me). I will probably go to 32gb then and either find a way to increase my budget or take off elsewhere on my build.

Thanks

Well, if you post your full config + link, budget, uses, monitor, etc. as linked to in Martinr36's post above, I'm sure one of the helpers can tweak/trim it to work better.
