GA-Z77-D3H (rev. 1.1) problems and more problems

[vertelnekeer]

Hello Everyone.

I recently have buy this mobo, and tbh i have some problems and not sure how to solve them.
Before i write i want to say that i have no much experience with bios and features.

Basically what i need is to have all USB ports enabled to use USB 2.0 devices because i dont have any 3.0 device.

Also very often i am getting this error, after that all usb devices get frozen and i need to reboot manually.




Also i have KINGSTON DDR3 8GB (2x4GB kit) 2400MHz KHX24C11T3K2/8X HyperX XMP Beast  memory
and i see in bios it working only on 1600mhz instead of 2400MHZ. But this is not big issue how big is with USB devices.

Any solution how to enable USB 3.0 to allow work of USB 2.0 devices.

My devices connected on USB ports:
1. Logitech MX518 Mouse
2. Razer Blackwidow  Keyboard
3. Logitech Web Cam

I have updated bios to latest version, also all drivers.

Please help

Thanks in advance.

You can set the timing of you ram manually to run at the speed you want as long as motherboard allows that speed. You can download and install cpuz to help you out. It shows all your timings. Best and easiest way is just set ram multiplier up to what speed you want. Your motherboard should not have a problem going to 2400.


I would unplug 1 USB device at a time to see which one is causing the power surge it may have nothing to do with motherboard but a faulty device.
