Changed the power supply units in my PC to match the new ones I received, bringing them to CL16-20-20-38. From what I can tell on the site, everything else remains unchanged—1.35v on both. Both models have an SPD of 2133mhz at 1.2v (CL15-15-15-15-36), no ECC, and the only variation is at 3200mhz where one has CL16-18-18-36 and the other CL16-20-20-38. Shouldn’t there be any issues now?
