I am asking, because I am putting together another build, more budget friendly, for a friend.  Well that and I am curious.

What is the differences between these two boards?

I heard the k4 was going eol, and this was the replacement.  I also heard the mods here say that the gaming x has some better components.  However, the gaming x is cheaper somehow?  $110 on newegg atm, after mir.

I also heard another forum member say the exact opposite, and claimed the k4 was too good for the price.  Not sure what to believe... Some clarification from asrock about the exact differences would be great!

Is he neither able nor willing? Then why call him God???

These two boards are virtually identical in their construction and features. The only main feature difference is the Gaming K4 has two USB 3.1 ports, while the Gaming X does not have any USB 3.1 ports.

There may be some differences in components on these two boards, prices for some chips have increased dramatically and can no longer be used on budget oriented boards like these. Specific chip models such as the VRM chips will not be high end chips on boards at this price level, so are not specified in the specifications. Both boards are 12 phase, 8 + 4 VRM designs.

The Gaming Z is simply on sale at Newegg now (ending in six days), while the Gaming K4 is not. That accounts for the current price difference, and is not related to the board itself. The MSRP of both boards is identical, $159. The Gaming X also has a better rebate, since it is a new product.

The Gaming X is also quite limited in OC bios options as well, see my older post here:

http://forum.asrock.com/forum_posts.asp?TID=5400&title=x370-gaming-x-no-llc-offsetv-fixedv-values-only

summary of my post:
-The Gaming X is lacking LLC (CPU+SOC)
-Voltage can only be set to Offset mode
-Only fixed Offset Voltages can be selected from a list
-For CPU a max negative value of -100mv is possible
-SOC can only be increased, no negative values possible

Surely the bios will be updated with those things though.;

Do you a source for that?

i really hope more options will come with updates.
But if i read what Xaltar wrote in another thread i doubt LLC will be added as its not supported:

Not a direct quote, I would need to go through my mail for that but that is the gist of it.

Yah, I found that comment to be puzzling.   

I looked at the mb comparisons, and I noticed the k4 doesn't list 3200 (OC) as a possibility.   Also, the - IR Digital PWM was replaced with -Digi Power design, which I would assume is a downgrade.

Also no usb 3.1, but I don't care about that.

yes, i actually got better memory OC with the Gaming X.
On the K4 i got my 2x16GB up to 3066 after lots of trial and error.
On the X 3200 was quite easy , could also post with 3333 but didnt really try for long to get it stable, was quite unstable so i didnt bother.

But on the other hand i was not able to get my 1700X stable at 3.9ghz anymore, i think its cause of the vdroop, at least not with 3200mhz ram. The missing LLC pays its price here i guess.
