Windows 8 or 7? Is it one particular storage device, or any usb 3 device? I've 4 external usb 3 drives, none of them exhibit such problem

Windows 7 x64 using any USB3 storage device or hub. Strangely, I can connect several USB storage devices to a USB3 hub and when the disconnect occurs only the USB3 devices are affected and any USB2 storage devices remain connected.

I am using 2x2TB in an external enclosure and no problems (Win 7 Ultimate x64 UEFI with Intel® USB 3.0 eXtensible Host Controller driver v2.5.0.19)

I'm using 2.5.1.28. I'll try rolling back to the version you are using and see if that helps.

Thanks for the help guys.

Seems that either nobody has this problem or nobody is using USB3. Is anybody at least able to confirm that they have been able to successfully connect USB3 storage devices to this laptop for long periods without disconnection?

I'm having problems getting my USB3 ports to work. They work fine with USB2 devices but USB3 devices are randomly disconnecting and reconnecting whether connected to my USB3 hub or directly to any of the USB3 port. I have tried both versions of the "Intel USB 3.0 eXtensible Host Controller Driver" found on the Sager website and I've experimented with shorter cables. I've also tried downloading newer drivers directly from the Intel website but the problem persists.

Anyone else experiencing this or have any suggestions?

The latest BIOS & EC v5 do quiet well, you can find them here.

If your phone disconnects then its a driver issue and not BIOS related, have no problems here with my HTC...

This may be a stupid question but is the BIOS you have linked to here safe to use on any Clevo W230ST, regardless of Country or "brand"?

My 4700MQ is stable at -80mV but anything more than this and I get frequent crashes when doing anything intense. I've found undervolting only gives me a minor decrease in temps.

I've underclocked to 28x when 3 or 4 cores in use and this has made a huge difference to temperatures with no real performance impact. I've kept the stock multipliers with 1 or 2 cores in use.

Any owners of the W230ST tried undervolting the CPU?

Mines has an i7-4700MQ and currently undervolted to -80mV and decreased each multiplier by x2 for stability (without crashing while mutltasking between 2-3 games).

Just wanted to know what everyone else has tried and the success they made when doing this.
