CPU works flawlessly with PBO -28 and Curve shaper -5 at high frequency range. Memory runs at 6200 out of box with UCLK=MEMCLK with old BIOS, should run at 6400 with a X670E motherboard.
These parts are super stable under TM5, Prime95, Aida FPU and all sorts of heavy stresses on a middle range B650 board. This bundle is a bit on expensive side, but they are well worth it, and still cheaper than a retail purchase.
Shipping is acceptable if you would pay for upfront costs.
Expect a 19000~19900 score on Cinebench R23 with decent cooling, regular 7700X are around 15800~16000
