the 424 bios for me seems about the same as the last one the 418 that ive been running, nothing new or noteworthy (but i dont run raid and other stuff that people were having problems with), i am using the modded ones with the straps uncovered but none of them work like the 333 or 400 strap, the 250 strap works but its just like the 266 and i dont think it actually changes it

i could be wrong but none of my subtimings changed and sp1m was still the same time
