I run this mobo in my daughters rig with 2 x 16GB 3000mhz, 3600x and currently running an RX570 (GTX 1060 3GB prior) without issue. Make sure you are running the latest bios and grab your intel network drivers from Intel. I had issues with ASRocks network drivers that would cause random BSOD's.

Running Windows 10 with latest Radeon vid drivers and AMD chipset drivers as of 3-23-20. 1080p 60hz monitor with wired keyboard and mouse .. if you are running wireless, that could be a source of "input lag".

This little motherboard has been a good performer with a 2200g, 2700x and now 3600x cpu's. Using 2200g for video, then GTX 1060 3gb and now RX 570 4GB without issue. Fortnite played surprisingly well on the 2200g.]]> Tue, 24 Mar 2020 00:00:23 +0000 https://forum.asrock.com/forum_posts.asp?TID=8672&PID=73743&title=ab350-gamingitx-pcie-x16-switch-and-latency#73743 <![CDATA[AB350 Gaming-ITX, pcie x16 switch, and latency? : input lag is a monitor thing ]]> https://forum.asrock.com/forum_posts.asp?TID=8672&PID=73742&title=ab350-gamingitx-pcie-x16-switch-and-latency#73742 Author: gizmic

I'm glad someone else also has the same problem with this motherboard. I've been struggling with input lag for a while now, even swapping GPU's (I've tried RX 580 and GTX 770).

Was that PCIe Gen 1 setting a permanent latency fix for you?

Also, can you point me over to the reddit thread that you mentioned, where people were discussing the busted PCIe bus on this board?

Thanks!]]> Mon, 23 Mar 2020 15:27:41 +0000 https://forum.asrock.com/forum_posts.asp?TID=8672&PID=73737&title=ab350-gamingitx-pcie-x16-switch-and-latency#73737 <![CDATA[AB350 Gaming-ITX, pcie x16 switch, and latency? : Using PCIe X16 Switch -&gt; Gen...]]> https://forum.asrock.com/forum_posts.asp?TID=8672&PID=51398&title=ab350-gamingitx-pcie-x16-switch-and-latency#51398 Author: siz

Using PCIe X16 Switch -> Gen 2, it crashes after playing 30 secs of CS:GO..  No apparent latency problems..

EDIT:

Reverting Windows to 1709 does not solve the issue :/

Hello, 

Igot the Asrock Fatal1ty AB350 Gaming-ITX/ac yesterday, and I've had bigproblems with latency which I found out because my audio and mouse stuttered inwindows when just loading programs. In games it was awful. I had alreadyupdated BIOS to 4.60, installed latest AMD chipset drivers & Nvidia driversand updated Windows 10 (& Intel drivers LAN through windows). 

UsingLatencyMon I could see big delays in especially dxgkrnl.sys, nvlddmkm.sys, ntoskrnl.exewith > 200 ms in highest execution time (could also see some delays inndis.sys and wdf01000.sys) Ouch


RemovedNvidia drivers and tried with older and older drivers, no luck. Disabled allkind of power management options, no luck. On reddit someone had tried switching to PCIe x8 and it worked for him. SoI tried switching to 2x8 in the Bios under 'Advanced -> AMD PBS -> PCIex16/2x8 Switch'. Didn't work. However, through trial and error (still latency and some system crash while loading games), using thefollowing settings removed my latency problems Big smile

  • PCIex16/2x8 Switch -> x16
  • PCIex16 Switch -> Gen 1
  • PromontoryPCIe Switch -> Auto

 

Whatis difference between 'PCIe x16 Switch' in Gen 1 and Gen 2? Are with talkingabout PCIe 1.0 vs 2.0 -> 4 GB/s vs. 8 GB/s bandwidth, shouldn't it alreadybe PCIe 3.0 x16 with 15.7 GB/s? Will it affect performance? If it does, what to do?


Lastly,on the motherboard page https://www.asrock.com/MB/AMD/Fatal1ty%20AB350%20Gaming-ITXac/index.asp,it says USB 3.1 Gen1, however on the box, in the manual, and on the shroud asseen on the page it says USB 3.0. Which is it? Maybe update the page..


My system:

  • AMD R5 2600X
  • Asrock Fatal1ty AB350 Gaming-ITX/ac
  • G.SKill Ripjaws V F4-3200C14D-16GVK @ CL14 3200 MHz
  • Palit Gefore GTX 1060 DUAL 6GB

Thanks in advance!
