thats silly, support spreading FUD about overclocking.run the memory at default spec which I think is 2133 mhz and see if it makes any difference
you could entertain them, but I guarantee RAM is not the issue here
and if it was, thats even worse for them. how do you design your product that breaks when ram speed is different. Haven't we been through this with Turbo button 33/66MHz cpu speed toggle?
