DDR 4 2666 vs 3200 vs extra cost

[lake2069]

I am wondering if DDR 4 2666 is still suitable on modern platforms which I still have and works , as I am replacing a motherboard and cpu from the 5820 days due to faults and am looking between the amd 5900x and intel 10850k, I already decided on boards for either platform and further down the line still to decide on latest 3080 or read up on amd cards once all are in stock on a water cooled 3xs system any advice be highly appreciated

There should be reviews on memory scaling which will answer the performance issues. The sub 3000 ram is usually worse than the 3000+ in terms of whether you can OC it too as they generally use crappy ICs.

On a 5900X, you are spending a lot of money on that machine so cheaping out on the ram seems a bad idea.

But honestly it depends on what you are doing. My Ryzen 3600 based server uses 2666 ram (fastest ECC you can easily get) and I tried the stuff in my main 3700X PC. I'm sure there would have been a measurable difference, but I couldn't *feel* any difference between that and my usual 3200 stuff.

We have a couple of Athlon 3000G machines at work that even use 2400 ram in single channel with integrated graphics. Surprisingly usable, but I don't think I would want to game on that.

There is some 2666 ram on Amazon atm for about £45 for 16GB. Performance is lower and usually I would say to get at least 3200 ram, but heck that's cheap.

At first, everything more that 2666HZ is OC (very easy to set,but sill OC), AMD should give you more power thanks to faster memory that Intel. If you choose ryzen, try set memory at 3600, his inner line (infinity fabric) can work witch that speed so you get best performance.

Ryzen 3000 and 5000 series are officially specced to 3200MHz ram. The earlier Ryzen CPUs and the 3000 series APUs are 2933MHz.

RAM prices are super low these days. Prime day we saw 3600 micron E dies for £46. You should be able to see similarly good deal on Black friday.
