Suggested DDR5 specs for an i7 12700K?

[Blade-Runner]

So after holding off on upgrading my aging decade old build to wait it out for the next GPU cycle, all things being equal I am gravitating towards Alderlake unless Ryzen 7000 impresses.

In speccing out the build I have initially chosen a G.Skill 32GB DDR5 Trident Z5 C36 6000MHz kit (naturally thinking the faster the better), but given it is hideously expensive I am wondering whether the increased bandwidth over say a C36 5600Mhz or even a C40 5200Mhz kit is worth the cost.

Would appreciate any thoughts from the resident gurus.

Get the cheaper kit.

Having now read this Anandtech article it certainly looks like the increased Mhz has little benefit...

So what's the point in getting faster modules? Is it likely to improve how far you can overclock the CPU?

You get more FPS but it's not worth it because the gains are so minimal. Plus the mobo has to be able to handle the higher speeds too, which they all can't do.

I had a Z690 Master and a kit of Aorus DDR5 6000mhz memory. I seen no benefit going to DDR5 from DDR4 which I ran previously in an Elite AX DDR4 board with my 12700K. After getting memory errors that I couldn't really point to if it was the board or the memory I sent both back and went with DDR4 again. Just my .02.

I have G.Skill Trident Z5 5600C36 with 12900K/Asus Z690 Hero, works perfectly. I went safe as this runs at 1.2V while the 6000 is 1.35V.

DDR4 is a more reasonable choice, but if you don't upgrade often then maybe DDR5 is a better option.

5600 and up are usually the better chips. I have a 5600mhz CL40 set of Kingston Fury Beast and it went to 6000mhz easily. I haven't tried lowering the timings yet.

This, get 5600+ for the SK Hynix DIMMs, they often use Micron at 5200 and under and they are already topped out.

If you're doing 4 sticks though, probably whatever is the cheapest you can get that you like.

I will stick to 2 dimms given the theory that 4 sticks can cause issues when overclocking. I would have liked to have gone with 64gb but that will cost more than the CPU and Mboad combined.

Is there any observable benefit from lower timings?

based on benchmarks----there seems to be a noteable improvement between 40 and 36. 32 isn't worth it, at the current speeds.

this is a decent bundle. Hynix, been running stable for me at stock speeds.
