Voltage adjustment experiments done on Fury X - abysmal results with scaling vs core clock increases:

That's basically half the fps gain for each MHz gain, proportionally-wise!!! It reminds me of the scaling of overclocking AMD's bullsh*coughs*dozer or pile-o'turd-driver CPU's!

Looks like even stock-clocked HBM1 isn't plentiful already for Fury X cards, poorly optimized with default 512GB/s bandwidth, despite having much larger L2 cache than Hawaii.

Warning: W1zzard said that +40mV would be the max for safe continuous operation, even with overclocked watercooling pump. Anything more overheats the VRM's, especially given the fact that they're already directly cooled by a copper pipe nearby, connected to the watercooler.

Ok with science that the big bang theory requires that fundamental scientific laws do not exist for the first few minutes, but not ok for the creator to defy these laws...
