also mate, watch out for lying companies. MSI and ASRock are just plain liars, they put in their marketing materials that they use digital PWMs for Z77, but the truth is asrock is lying 100%, they actually changed from a digital Chil controller to a pure analog Intersil controller, thus rendering their PWM analog and not digital.
MSI likes to say hybrid-digital, but the truth is they never said this pre X79, and they are using the same PWM, they are just lieing, as gigabyte switched to digital now everyone wants to go digital, but they can't because of price and quantity of the chips available for sale. Also digital doesn't allow good phase doubling techniques, they only result in doubled driver oputputs when it comes to digital PWM scheme doublers, so you can't do more than 1 integrated power stage per phase, unless IR makes a new doubler which can, which I think they might. Otherwise they ill have a true 8 or 6 phase PWM with doubled up phases, so 1 phase would have the number of power stages as two, and add a second inductor and it looks like 2 phases but is actually `1 phase.
But who can protect you? reviewers should, however their knowledge of board components is that of a dolphin's knowledge of the universe and space. THey are oblivious. However I review boards, and I don't lie about what type of components are used, i will even link datasheets when needed, however just never take any reveiwer's word for it, always check for yourself, datasheets on everything are available if you look hard enough.
I saw one reviewer take MSI's hybrid digital claim, and say it was fully digital, reviewer even wrote fully digital, i wanted to kill him, and i felt like giving him a curb job for his utter ignorance he deserves not to review motherboards but more importantly shouldn't even own a computer he is so ignorant he might think a Microsoft owns Apple or some outrageous thing like that.
BTW why can MSI claim hybrid digital, well because of SVID. SVID is a digital 3-wire bus which allows the CPU to communicate its requested voltage to the PWM which then controls the phases, however as soon as it enters any analog PWM such as those made by uPI(MSI uses uPI) and those made by Intersil (ASRock uses intersil for Z77 and beyond) it is immediately converted to an analog signal through a analog to digital converter(ADC).
Good luck mate, it really doesn't make much difference if analog or digital is used, analog is a bit easier to implement, more straightforward, and faster, but digital gives more user control, gives better transient load control, and is more precise period.
I guess since asus dropped asrock(asus is selling their 30% of share of asrock), now asrock can't use the 8 phase digital PWM anymore, that is my guess. BTW the fact that asus owns 1/3 of pegatron, that should confirm what I have been saying all a lon that no one wants to observe.
