I am building a machine for my “productivity” loads (mostly large code bases compilations + lots of virtual machines).

Main specs: intel i7 13700K, no gpu, 1tb m.2

Because of vms I run, I need some ram, so I would buy 64gb. Should I go DDR4 3200 or DDR5 5600?

DDR4 is quite cheaper, also motherboard is quite cheaper, so it adds up. But would DDR4 be a bottleneck for cpu?

Most reviews talk about gaming, but maybe ddr4 and ddr5 effect my workloads different?

    DDR5 because 4 is obsolete and why by an obsolete mobo to suit obsolete RAM?

        You can fit obsolete tech to new tech. I believe a better option if you want to save money would be to get a cheap DDR5 kit and a DDR5 capable board and, in a couple of years, upgrade the ram to a nice overclock kit.

        By obsolete tech I didn’t mean it’s no good, just that you’re committing yourself to a product that’s being phased out.

          Oh yea totally, but for this gen its not yet obsolete, my current kit has been thru 3 builds now.

            Since you already had DDR4, that makes complete sense. I sold my ram, mobo, and CPU when I went to a 12900k.

      I wouldn’t say it’s obsolete at this point lol. But in another year or two it will be obsolete.

      Once the stock speed and timings of DDR5 is able to overcome the latency deficit between DDR4 and DDR5, DDR4 will become obsolete.

        I might need to read more tests, but I had believed we passed that point at about 6200mhz on most kits.

          With extremely tight timings you can get close to the latency of DDR4. Within like 10-12ns I think. But I think that’s on much faster kits.

          I’ll have to look around and double check lol.
