There's a very good chance the 8 VRM boards will be able to overclock boost performance FAR beyond the 4 VRM boards.
These are not thermally limited as-is on 0.95. If they are limited, they're limited by VRM current or perhaps decoupling capacitance or other
Prepare for further shitstorms, anyone with a 4 VRM board will be like a cripple trying to keep up against Usain bolt
Oh and those VRM modules have the board level connections as BGA-style underneath the PCB. So you're not adding any components yourself! So go fuck yourself, everyone who doesn't have a reflow oven
If you want better performance out of having 8 VRM's over 4, you will have to code it yourself. I highly doubt KnC is going to favor the earliest adopters who have 8. This place would become a bloodbath otherwise.
I was hopeful that maybe these things could be future-proofed for the next couple of months and pushed to 700-800GH with ADHD Marcus and his love for tweaking.
I'm not going to play armchair engineer. I think if they would've been useful to leave on, they would have. I don't think this is about saving money on those tiny parts that are probably worth pennies.
