Comments
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

2025-01-08 21:05:43 +0000 UTCI 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?

2025-01-08 20:25:42 +0000 UTCupto 1.5V should be fine

2025-01-02 17:44:30 +0000 UTCHi 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…

2025-01-02 17:13:51 +0000 UTCI 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.

2025-01-02 03:27:03 +0000 UTCthey keep crashing every time I try them. Ryzen seems to really hate them.
