Hi all,

It seems I'm not the only one suffering from terribly slow USB3 speeds. Purchased a new external HDD yesterday in the bank holiday sales. Unfortunately the transfer speeds were crazy slow. It started off well, but soon dropped, and then starting going down to 0 bytes per second every minute or so.

I decided to reinstall windows (it needed doing anyway). This made no difference. I then installed the latest drivers both from gigabyte, then from intel. No improvement.

I've tried all the device manager tweaks, bios updates, checked various bios settings, moved USB ports around. This also happens on USB3 flash sticks as well so it's not a fault with the drive.

I'm using the latest beta bios due to the ram issue with this board, but also happens on the latest official version as well.

In the end I got so annoyed with it, I broke the drive out of the enclosure and now use it internally.

Just wondered what on earths going on?

I did read on a forum that it's a known issue and you have to use a hacked USB3 driver :confused:

Years ago I had a similar issue which was down to overclocking, but my system is stock

anyone experienced something similar?

There is an issue with the ram timings at the min which causes blue screens. Use the beta bios and turn off XMP. Make sure the volts match what the memory needs and set the timings correctly. That reduces 99% of issues. If you still get them, lower the speed.
