ASUS Crosshair X670E Gene load line calibration test results
Added 2022-10-07 20:52:59 +0000 UTCAll measurements are taken with a Rigol DS1054Z unlocked to 100MHz bandwidth.
Level 8 LLC is as expected absolutely horrendous with a worst case scenario undershoot of 140mv (difference between minimum measured voltage and average RMS)
Level 7 LLC is better but still has a lot of undershoot at 90mv
Level 6 LLC is ok with around 60mv of undershoot
Level 5 LLC really is the best. With just 40mv of undershoot
Level 4 LLC doesn't do anything for the undershoot and somehow ends up adding a bunch of overshoot with maximums hitting around 1.37V instead of the 1.31-1.33V of the previous LLCs
Level 3 LLC is just more of what Level 4 did.
Level 2 also doesn't help anything
Level 1 also doesn't help anything
Since this testing was done with linpack here's the memory configuration:
Linpack Xtreme V1.1.5

The CPU should be getting around 800Gflops with these settings.
The motherboard was provided for testing by ASUS.
