Decent features and user-friendly bios
I had originally tried to write this review for outletpc jp, but they don't seem to accept english reviews. However, i did buy this product off outletpc. Am using this motherboard in the following build:cpu: amd - ryzen 5 1600 3.2ghz 6-core processor (oc @ 3.8 ghz, 1.25 v)cpu cooler: corsair - h80i v2 70.7 cfm liquid cpu coolermotherboard: asrock - ab350 gaming-itx / ac mini itx am4 motherboardmemory: patriot memory patriot viper 4 series ddr4 16gb (2 x 8gb) 3200mhz kit 16 ddr4 2400 mt / s (pc4-19200) dram pv416g320c6k ssd: samsung - 840 pro series 256gb 2.5 "solid state drivehdd: seagate - barracuda pro 6tb 3.5 "7200rpm internal hard drivevideo card: gigabyte - geforce gtx 1060 3gb 3gb mini itx oc video cardcase: silverstone - sugo sg13b-q mini itx tower casepower supply: silverstone technology platinum certified single + 12v rail atx power supply, ps-st55f-ptcpu and ram oc were easy to set up. The motherboard came with version p3.00. I immediately updated it with 3.10. Even though xmp was meant for intel, this bios lets you use the load the xmp profile after you update to 3.10. I am able to run at 3200 mhz stable with my ram. In my original post, i mentioned there were no options to set the manual timings, but apparently i was dumb and didn't scroll do. They exist. With my current oc settings: i idle around 30 c and hit 60 c running cinebench. I'm not sure how this compares to other mini-itx builds, but it's fine for me.

A great choice for budget gamers
I used this motherboard in my friend's mini-itx system in october of 2017. I built his computer and overclocked it. This board handles overclocking very well and have no complaints.Case: fractal design nano s (windowed)power: evga 450bmotherboard: asrock ab350-itxcpu: ryzen 3 1200 oc (3.9ghz @ 1.35v)cooler: stockram: 8gb corsair lpx (3200)storage: pny cs1311 240gb ssdgpu: zotac gtx 1050ti mini

Great board
Bought this mb for a mini pc build. Performs great with 16gb 3400mhz patriot ram (pv416g340c6k), was able to get it to 3333mhz and extremely stable. A ryzen 7 1600x, zotac geforce gtx 1050ti (4gb ddr5) graphics, two 500gb samsung evo 850 ssd's all in a cooler master elite 110 case. Cpu cooling is done with a corsair h60 liquid cooler. The system runs like a champ and unbelievably small. If i need more speed, i can just pop in a ryzen 1800x or better when the ryzen ii's are available. The board is awesome and i highly recommend it.

Perfect match with my fractal design core 500 and mi amd 1600x.I got de v2 heatsink for the vrm (large) and works flawless.
By Mohamed Guerrero
Not as stable as originally thought... Though games well
I have built about 30-40 computers now. And this board is up there as far as speed and stability... Except for the intel parts... My bluetooth has completely corrupted its windows side of things and the wireless cant seem to configure its own tcp stack... This thing is brand new so i figured its a driver issue that hasn't been debuged yet... So i looked around online... Not really finding anyone else with my problem... So i think its just bad hardware... So i checked it... Its fine... So i really don't know whats going on with this buggy little board... As well it heats up pretty good in the mini itx build... Had to add two extra fans to a case thats not designed for them...Overall im not happy with it... If i can debug the situation or if it turns out to be user error ill update my review but for right now... It gets 1 star for fitting and 1 star for gaming... And looses 3 stars for lots of bluetooth issues, and a very bugy wifi adapter...And dont forget the 125f idle in my mini itx box.... (that board temp not cpu (cpu was only 89f))
By Aapo Keranen
Works as it should. Wifi antenna is actually good.
Boots fast as hell. Don't enable am4 boot training and fast boot at the same time, you won't be able to get into your bios easily.

Outdated bios
Outletpc, you need to please let the customers know that this has an outdated bios!! "well, why don't i just update the bios by flashing it?" because that would mean that i'd have to buy two cpus!!! What outletpc should do instead, it is to have these things drop-shipped from asrock with updated bios, even if it means that the customer has to wait a little longer, instead of selling these things with the 3.0 version. 3.0!! That's the original bios from back when it first came out!!!Cpu - ryzen 2400g?€”?€”?€”?€”update 2/17i was able to update the bios, but now it won?€™t boot. It?€™s cool to look at the cpu fan spinning, and that?€™s it. Stay away!Amd supposedly makes a cool apu with vega video. I won?€™t know. They may want to make a mobo for it too.
Ships with old bios - cannot be updated without having an existing cpu that already works in the board
Do not buy this board if you are looking at any recent ryzen cpu/apu unless you already have an am4 cpu you can put in this piece of crap to flash it. The bios as shipped will not support the latest cpus and asrock support is useless.
By Donald Elliott
Works as intended. Works w/2200g and 2400g but needs bios upgrade first.
The motherboard works as intended. I was even able to stuff ecc memory into it (though i'm not 100% sure its actually running in ecc mode). I had to dock asrock a star because the mobo shipped with an old bios that isn't compatible with the newer amd 2200g or 2400g cpus. Fortunately i as well had a ryzen 7 i could plug in to upgrade the mobo. I think amd has a solution to this problem for people who don't have compatible cpus lying around, google for it (they ship you their oldest am4-compatible apu to use to upgrade the bios, then you ship it back to them, or something like that). In anycase... They lose a star for that.I'm not a big over-clocker, but i did play with the settings a bit. I think even the latest bios (as of this writing, just after the cpu was released) has not quite caught up to the 2200g/2400g because the o.C. Settings didn't quite work as expected. But i could get it to run 3.8ghz on all cores/threads in o.C. Mode. For some reason, though, i couldn't get it to run at 3.9ghz on all cores/threads in o.C. Mode even though normal mode will run it at 3.9ghz on one core. Might just be a cooling issue.M.2 slot is on the bottom of the board. Haven't tried it. Usually i just run with a few 2.5" hot-swap enclosures for the case.Addendum - still working as expected. I'm glad people found my review helpful too! I did learn one important thing about overclocking ryzen 2xxx series parts with the 2700x i just got (in another mobo, not in this one!) that's applicable to all ryzen systems, and that is... Focus on the overclocking the memory first, that gets you 90% of the performance boost, and the 2xxx series cpus seem to work really well with rated high speed memory. The older 1xxx series of cpus had lots of problems, though over the last year bios updates have fixed most of them. But the new 2xxx series cpus are solid as a rock with high speed memory.Addendum - one final note on this motherboard. It has six vcore vrms but its running 3-phase mode, not 6-phase mode. It isn't really designed to accommodate something like a fully overclocked 2700x, for example, which can eat 180w of power at the wall, and the vrms will probably get a little too hot for comfort with a 2700x stuffed even at stock settings (so if you do it, make sure your case is well ventilated). A 2600x (or 2400g) is the better fit. That said, for standard overclocking on a 2xxx series cpu you actually get most of the performance from the memory profile and not by overclocking the cpu itself. If you purchase high speed memory, say you get some 2933 or 3300 ddr4 or something like that, remember that you have to actually enable the higher speed memory mode in the bios. Stock settings boot at 2133. In anycase, this will get a ton of performance without having to actually overclock the cpu itself and the system will remain relatively cool. Again, remember this mobo has fewer vrms, runs only 3 phases... You can stuff a 2700 into it but don't expect good overclocking, and i probably wouldn't want to stuff a 2700x into it.-matt
