For instance Vega 64 main GPUhas a 12 Phase VRM but the controller only supports 6 phases, the doubler takes one of the phases signals and splits it every other one between two VRMs. (kinda like AFR SLI in a way). This lessens the load on each VRM by roughly 50%. Well this is a basic understanding of it.. This guy explains it around starting around 8min 20sec to 10min in the video.

Doubler means chip that takes 1 PWM signal and splits its cycles into two, it cuts the switching frequency coded in the PWM by 2. For example IR3599 or 3598 are such doublers

If only I could make use of the 8x2/16 phase VRM of my P5 Deluxe (its extremely picky about FSB speed+RAM, and multipliers higher than 20), so no extreme overlocking with my X6850.

Saw it off and solder on a different power-requiring piece of hardware

I doubt it would handle 2.2-3V.......

Get a GPU with crappy VRM, ghetto the 16 phase on it and go break records on HWBot

6 phase Digital VRM> 16 phase/8x2 analogue VRM (though ASUS calls it a true 16 phase VRM, and I still haven't found solid evidence of it being doubled)......

Maybe you could make your own topic about this, but anyways

So doublers basically lightens the load on each individual VRM, but will it show noticeably performance increases.
