Is using DDR5 greater than 5600 considered overclocking for Z790?

Intel specifies DDR 5600. Is using something faster going to overclock anything?

If you buy RAM with an XMP profile for DDR5 6000 and use the XMP profile, you are not overclocking the RAM.

However, you are technically overclocking the memory controller. Because the memory controller is rated and set for 5600. Eventually, you have to add extra volage to the memory controller, to keep it stable with some really fast and/or low latency RAM.

Thanks. I haven't been interested in overclocking for quite a while. I just want to put something together with high quality stock speed components that doesn't need to be tweaked and fiddled with.

I guess I am looking for a good set of low latency DDR5 5600.

Well you are and you are not.
The actual memory chips are overclocked but they are tested and warranted to that speed by the company that assembles the stick (This includes 5600 sticks)

A high speed RAM kit shouldn't need any tweaking with a half decent Z790 MB and a 13 series CPU all you need to do is enable one setting in BIOS XMP.
Intel sees some nice gains from higher RAM speeds so I would go with at least 6400 maybe 7200+ unless wanting to run over 32GB.
 
What is the reputation of G.Skill these days? They have CAAS 28 DDR5. I remember trying their RAM once a very long time ago and I had stability issues. I switched to Corsair and the issues went away. I have used Corsair ever since, but they don't have much low latency 5600.

For intel 13 series + z790 combo, those 2 kits are belong to low-ish binned one. I'm afraid that kits can't go past 5600 as all you can do is tuning the timings. Usually xmp 5600 are based on micron chip.
 
Good question. I am actually wondering why my kit defaults to 4800 when I have a Z790 and a 6000 ram kit? Isn't the default 5600?

Probably because your JEDEC profile for the kit is 4800 check with CPU-z on the SPD tab, it will show the profiles with JEDEC being the default.

Corsair has fallen behind as far as RAM goes and there is a bunch of brands I would take over them.
G.Skill having MB QVL on there site is great and I love that Kingston shows how many ranks there sticks have and detail the SPD profiles.

Yes. Those different XMP profiles being listed is exactly what I was looking for.

I think I have settled on this G. Skill 6400 CL32. It has the same 10ns latency as the 5600 CL28.

Oh I thought the board and CPU would default it to 5600 since it's raptor lake and z790 but it's the rams default at 4800. That sucks I wish it defaulted to 5600 at 1.1 vs 4800 at 1.1.
Also I can select up to 6400 when xmp is enabled with a selectable pre configuration in the BIOS at 1.45 vs 6000 at 1.4 default xmp. And this is for a 64gb kit 2x32 at C32 latency.

For sure. Despite their silly name and very gamer aesthetic, they seem to be who mobo makers like. If you check an ASUS QVL list, it is always just chock full of Gskill kits.

As an aside: Get memory off the QVL list for your board. While other memory CAN work, the memory on that list WILL work. As memory gets more complex and faster, the specifics matter more and you might well have two ostensibly identical parts, one that works and one that doesn't. Goex extra double when you are pushing things like with XMP RAM.

Looks like good value at $149us
The CL actually means very little to DDR5 performance, it is more about frequency and sub timings which are not advertised and often left to the MB to decide.

This 6800 kit for $210 may be worth the extra to someone looking at spending a bit on a expensive CPU and cooling solution trying to squeeze a bit more out of it.

After that the price really starts to blow out, a bit like the 13900KS.
 
Team group has PMIC cooling too on their DDR5 modules so it's worth it to look into them as well, I've got a bunch of Team sticks with no issues over the last few years for DDR4.
