I've confirmed a usb 3.0 stick working like this but the mouse is stuck on 2.0 regardless of where I plug it into. Instead of the 4+5 ports (and a usb c port) being divided equally between intel controller and asmedia, what I see is some kind of usb virtual power elevation situation where usb 2.0s get listed along as the regular composites, and the 3.0's would automatically get shifted onto the virtual "super speed hub" where they would run as 3.0s. Untitled.jpg (340.43 KiB) Viewed 1059 times Yes, you should be strategic, so don't plug a USB card into the slot that is most optimized for your x16 PCIe graphics card.īut it does suck if there are no other usable PCIe slots that does not steal a lane from the graphics slot or your NVMe slots, if you've plugged in your beaut of a RTX 3080 and a couple of NVMe SSDs onto the motherboard slots (and/or possibly something else), and have no spare lane for a PCIe USB card to bypass a hairpulling problematic USB implementation of a motherboard. However, it's a solution that bypassed USB mis-performance hell (latency/jitter) for a few people, and people at Razer confirmed that PCIe USB can be a solution for some users who don't want to replace their motherboards.

If your mouse driver CPU% is low (even at 8KHz) and your USB jitter is low, you don't really need a PCIe USB card.

Also the motherboard drivers can sometimes be more inefficiently written than the PCIe USB driver. Or produces more congested lanes than a sole USB device on a PCIe card. Or that there's a lot of EMI noise in the circuit traces on that other part of the motherboard (the lane used by the onboard USB ports - a motherboard manufacturer traced USB problems to this). Sometimes they share all the USB/SATA/etc processing out of the wazoo. But the problem is there's a lot of crappy motherboards. If you were to put a PCIe USB card onto one of the CPU PCIe lanes that would reduce the GPU to 8x lanes. , 23:09I'm currently using the direct CPU to USB lanes for both my input devices. I actually experience constant mouse stuttering and some kind of disruptions and somehow I cannot find any feedback or users with that mouse in any league community (lol discord, reddit).įor other games like Battlefield or Valroant it seems to be much better, but I get the ocassional kind of mouse lag spike there. Use the chipset ports for the rest (mic, webcam, dac, external hdd, usb hub).Īsking this, because, while the Huntsman works perfectly, running the Viper with anything above 1 KHz is terrible when playing League of Legends. Use an additional PCIe USB card for the mouse. In the manual/specification it states, that four USB 3.1 ports are run directly by the CPU and the remaining USB 3.0 and USB 3.1 ports are run by the onboard X570 chipset. I am trying to get a Huntsman V2 (8 KHz) and a Viper (8 KHz) running.įurthermore, I've got a X570 Elite mainboard. Is it just because of the additional power connection? I thought PCIe can deliver up to 75 W or something like that. The only user feedback here in this thread recommends the Inateck card with the Fresco chipset. Is there any list of recommended PCIe USB cards?
