If you are using a RTX2070 with hynix memory then it's better to go down to -502 for better performance and low power consumption but going over 100% power draw? No I'm just hearing this for the first time, OP are you sure you are using the latest msi afterburner for this? Do me a favour, download GPU-Z on your PC and look for the type of memory for gpu has, might be Samsung or micron? Check and reply
GPU-Z says that it's Samsung memory.
I'm pretty sure my Afterburner (4.6.3) is the latest, since I've downloaded it from MSI website something like 1 week ago.
