A source at VideoCardz report that a recent Eurasian Economic Commission, or EEC, filing shows that MSI Gaming is releasing a series of their RTX 3090 graphics cards with an updated GA106-302 graphics processor as well as the possible addition of a low hash rate. The opinion is that MSI is to add the LHR to give consumers the option of what version they are shopping for, allowing for more variety in the line.

Another interesting section of the EEC filing made by MSI was the return of their HydroGen series, a GPU that, at the time, had an in-house cooling system that was capable of high overclocking speeds, making it one of the more sought after graphics cards at the time. The last time the MSI HydroGen series was available was during when the Fermi architecture was available. Eventually, the HydroGen series was replaced when MSI signed with EK, a Slovenian company that creating cooling techniques for MSI's units, such as the Sea Hawk EK X. The AIO cooling module designed between MSI and Danish company Asetek was used for the Sea Hawk X series, changing the dynamic between MSI and EK.
