Do you want 64GB of DDR5? Do your research

[sblantipodi]

Ddr5 can be full of misunderstandings if you don’t do your research first




There is no single rank 32GB DDR5 modules currently.

This means that if you want 64GB of DDR5 memory you have two options.
Get a 2x32GB dual rank modules.
Get a 4x16GB single rank modules.


I'm using 4x16GB of Dominator 5600MHz C36 and I'm not able to drive them at 4.8GHz even with 1.35V on the memory and 1.25V on the memory controller/SA.


Don't make my mistake!!!

Well, I came from a 10 year old PC with DDR3, so I had no plan on investing in years old technology(DDR4) when I was upgrading for once. 🙂
And I still believe this is'nt the final performance of DDR5.

Have patience, things will get better.

This is the same reasoning I made but currently I have spent two times more than DDR4 to go slower.

Well, since I came from DDR3 I don't have any DDR4 reference so its ok for me.
I was very close to 100% stability in XMP-1 with 4 sticks 64GB at 5200MHz, that's why I have hope at least.
But I know I'm lucky as well.



However I was unstable at original BIOS 0503. Upgraded to 0702 and saw a lot more performance and stability.

However all these 08xx BIOSes after that has all been much worse stability than 0703 was so it makes me a bit worried.

With 0703 I could have computer on 24/7 and do lots of gaming and only get some strange crash every 3rd day or so.

You have a strange concept of stability. If the pc crashes while in game it's not stable �
So you don't achieved 5.2GHz with 4 sticks.

Well I said I played for hours for many days and in the end I have no way of telling if the crash was from a bug in the game, or caused by the RAM or caused by some bug with running windows 10 with e-cores and p-cores.

There are many factors here.

Hello,

As already iterated to you here: https://rog.asus.com/forum/showthread.php?126369-Maximus-Z690-and-Alder-Lake-Modern-CPU%92s-require-...

Always best to do some research prior to investing into a platform. Moreover, combining kits has never been recommended, so this isn't something that is new when it comes to running outside of base frequency as you are trying to do.

Hopefully, this thread will help others avoid making the same misconception and mistakes.
