Gigabyte Z68 boards were marked with X. None of them used digital design.

And read this one too.

The 'X' stands for digital voltage regulation (source). The Gigabyte website lists only the boards with an 'X' in the model name as having 'GIGABYTE All Digital Power Engine' (source). VRM on the other Z77 boards is analog then, if present. Feel free to throw in your two cents.

Damn, I like this guy. Well written. +rep smile.gif

The X standing for digital VRM is only for the Z77 lineup according to one of the sources I listed!!

yea dino works for gigabyte, so he would know. X standing for digital power could make sense, BUT not always. I have a Z77-HD4 right here, it uses a IR3564 which is a 4+1 digial PWM, but the board doesn't' have an X. So X would be boards with unlocked vcore, I haven't tossed the HD4 on and checked for vcore adjustment, I would guess however it isn't present.

holy crap dudes, guess what I just found out, the Z77-HD4 has vcore control, and it uses a pretty high quality 4 phase VRM. i am going to see how high i can OC, but this board has some crazy memory OC, it might become one of those really damn good values. All settings are present for OC.

so the X prob might just stand for extreme, maybe its just a marketing gimmick, or maybe it is to say X is for all boards which can do Ln2 OC. something like that, i will ask GB what it stands for.

For Z77 models, "X" = SLI-capable. If you look at THIS TABLE (midway down page) of all Gigabyte Z77 models, every single one that has SLI starts with either Z77X (full-size ATX), Z77MX (mATX), or is a G1.Sniper; every model that doesn't have the "X" (excluding the Snipers) doesn't have SLI.

Thanks for confirming that he indeed works for GA! That lends a lot more credibility to his post I linked to.

That was my original assumption too. But after finding Dino's statement I went with the digital VRM theory, especially since only those boards are labeled having 'Digital Power'. But you're right, in addition, only the one's that have 2x PCI 3.0 have the 'X' after the Z77 also. So it may well stand for Xtreme having both "Digital Power" (however GA defines 'Digital Power) as well as SLI/ xFire. Well, let us know what you find out atfer talking to GA, Sin0822!

The "X" can't stand for CrossFireX capability, since while all the "X" models can do it, some of the non-"X" models can as well.

I think that the SLI-capable mATX motherboard model Z77MX-D3H might be the model to prove/disprove some theories on the naming convention. Does it have the same type of power distribution/delivery systems as, say the Z77X-D3H? If it doesn't, then I think that "X" might solely mean SLI-capable, and indicate nothing else feature-wise.

Sorry, I meant SLI as well as Crossfire. Not sure about VRM on the Z77MX-D3H. We'll have to wait for Sin0822 to tell us. Having X stand for SLI might not go well over with nVIdia though, I would think that most people would associate an X in regards to graphics with AMD Crossfire.

EDIT: Here's another link for an overview of the Z77 7 lineup btw, hardware secrets isn't pulling up for me (at work biggrin.gif ).
