Most mobos simply have no clue on how to run these sticks. A good MBIST run with a custom Bus configuration gets them going quite nicely. Why MBIST? https://faculty-web.msoe.edu/johnsontimoj/ELE4142/files4142/DDR5_Spec.pdf

Do you know if M-die (2x24gb) can achieve similar results?

I did a few boards on those sticks with a 7500f. At 8000MHz aswell as 6400MHz. I didn't test MSI tho. What board and CPU you got?

upto 1.5V should be fine

Hi BZ, what is the max save VDDIO to use for daily? Without chance of hurting cpu in the long term. Trying to get 8000 stable…

I somehow managed to run them 8000 on asus x870e-e but with only bios 0606. Same timings wont even boot on newer bioses with agesa 1.2.0.2b, maybe agesa had something to do with it.

they keep crashing every time I try them. Ryzen seems to really hate them.

Hi buildzoid, do you have a plan for tuning the patriot viper 8200 hynix a die kits?
