I am a huge fan of Razer's RGB ecosystem controlled by Synapse 3. However, i recently did purchased more razer rgb stuff and it started making some problems. The problem is after i boot my pc, everything works perfectly fine. with synapse. My lighting works perfectly fine, all sync by razer synapse. I am using Ambient awareness feature for all ARGB devices, most of them are Razer devices (except for case fans and case argb strip). However, after about 20 min of usage, some lighting won't work, or stuck. (keyboard and firefly mat) Macro wouldn't work neither. and Keyboard is not working properly. Caps Lock and Number locks wouldn't work, function keys not working (unable to control volume, unable to toggle gaming mode on/off) I thought it was the compatibility of USB 3.2 gen 2 issue, so tried to replug my Keyboard into usb 2.0 ports, but it didn't solve the problem. I also tried to change setting in bios for usb devices, but it didn't help. After all tries, I disabled Razer Synapse at start up, and problem is gone. keyboard functions just perfectly. only down side of not having Synapse 3 on is the lighting is not controllable, and unable to use macros and remapping some keys. Does anyone have the same issue as i do? Maybe it's time to get rid of some of razer stuffs Here are the list of devices that is connected to my Synapse. RAZER BLACKWIDOW CHROMA V2 RAZER MAMBA TOURNAMENT EDITION RAZER FIREFLY HARD RAZER CHROMA HDK (2 RAZER STRIPS ATTACHED) RAZER TOMAHAWK RAZER CHROMA ADDRESSABLE ARB CONTROLLER (3 ARGB FANS, AND 2 ARGB STRIPS) ASROCK B550 TAICHI RAZER EDITION LEGACY DEVICES ( RAZER MAN'O WAR 7.1) I am also using Synapse 2 for this device. Summary Synapse would jam / stuck after some usage after pc boot up. unable to shutdown synapse. Chroma studio lagging, and lighting effect stops working. Keboard not working properly; caps lock, number lock, functhing keys, macros, remapped keys not working. Problem is gone when synapse is not running. Does anyone else have the same issue? Any suggestions?
