Im sorry to burst your bubble, but you are mistaken again.
Toxic uses Hynix H5GQ2H24AFR memory modules, which easily clock to 1800ish.
Dual-x uses cheaper Elpida EDW2032BBBG modules, which can not do 1800ish.
While you continue to say it can't be done there are people out there who are doing it

Such is life I guess... there will always be naysayers and there will always be people out there accomplishing things who ignore those naysayers who say "it can't be done".
