	My system Asrock Z790 pro rs intel I5 13600k OC to 5.5mhz 2060 rtx graphic 2tb WD Black SSD 64GBS (4x16) DDR5 5600MHZ 360mm 6 fan Water cooler 850w PS Master Cooler H500 case When adding 2x16 Corsair vengence 5600MHz DDR5 to my existing 2x16 DDr5 Cosair Vengenge 5600mhz. The Memory will only run at 4800Mhz.The best i could get after some tweaking is 5400mhz with XMP enabled . Has anyone been able to get 4 sticks to run at the rated speed? W.N.
