I have the exact same batch and pack date as you, still in the box though, I am waiting for some more parts

How does 450x9 handle?
I tried at 450x9 with 1.25V set in bios which is for me around 1.21 real and it booted just fine but then the Windows BSOD but it need a little tweaking i guess but it looks promising so far I don't want to overclock straight I will try to clock it more in a few days
