Let's say I have a motherboard whose stock PC3200 DDR memory modules are fed a standard 2.6 V. I now replace them with performance sticks, which according to the manufacturer need to get the "recommended" 2.75 V in order to work at their advertised timings.
Will the motherboard automatically adjust the memory voltage to 2.75 V ? If not, will the motherboard maybe choose looser latencies, and will memory modules then function properly at 2.6 V with no frequency decrease (still at 400 MHz) ?
