Z790 DDR5 max non-oc speed support ??

[digitaldreams]

Reviews of Z690 vs Z790 state that the new chipset supports slightly higher speed DDR5 than the old chipset, great. The old ROG STRIX Z690-A Gaming WiFi supported up to DDR5 4800 without overclocking (user manual).

Yet when I look at say the Asus ROG Strix Z790-A Gaming WIFI it gets a little confusing. Some reviews state Z790 will happily accept DDR5 6800, yet the memory compatibility chart on the ASUS website only lists up to 6600 with no mention of whether it is considered OC or not. The motherboard manual itself now strangely OMITS the list of supported memory speeds and what is considered 'OC' !?

Am I smelling a wee rat here ?

Well it's more what CPU you use, have a look at Intel's memory support for 12 and 13 gen.

Ah yes see it now, 13th Gen processors up to 7800 of 2x16Gb yet no 'OC' labels on any of them ?. Still iffy.....

The official spec from Intel is 4800 for 12th gen and 5600 for 13th gen (RPL only, 13600K and up), everything else is an overclock, which is why they put (OC) next to it in the specs for e.g. Prime Z790-A. For some reason the Strix Z790-A only lists underclocks, so I guess you'd have to go on places like reddit and OC forums, to find out what is being achieved with your chosen CPU and motherboard.

Hmmmm so the top non OC may be just 5600 even though ASUS claim 7800 is compatible in their charts. I'm currently running 3600 ram at 3200 on my Z690-A for max life and stability.
