(System Specs at bottom)
After receiving a Sandisk Extreme 3.0 Flash Drive, I've been speed testing with CrystalDiskMark.
On most plug-in attempts (using the front panel 3.0 ports), the "Other Device" menu shows that the flash drive is "Connected to USB 3.0". However, there are plug-in attempts where "Device can perform faster when connected to USB 3.0" is displayed, and the benchmarks reflect USB 2.0 speeds.
In addition, there are some plug-in attempts where windows 8.1 will re-install files for the operation of the flash drive (this only seems happen when I alternate plug-ins between the left and right 3.0 ports. Immediately re-plugging into the same port will not result in a re-installation).
The biggest problem is the left front panel 3.0 port and this only occurs when the left 3.0 port is operating at SuperSpeed. While the right 3.0 port never crashes when CrystalDiskMark is running, the left port will always result in Windows re-installing the "necessary files" for the flash drive causing the benchmark to error (and this only happens during the Write portion of the test, never during the Read test). After windows re-installs files for the flash drive, the port reverts back to 2.0 speeds and "Device can perform faster when connected to USB 3.0" is displayed. Re-running the benchmark while it's under this condition will not cause Windows to re-install any files for the flash drive.
When plugged into the back panel USB 3.0 ports, no weird behaviors are exhibited. (Although I haven't tested the flash drive in the back ports as extensively)
Here's what I've tried:
- Updating USB 3.0 drivers. (Both Intel and ASMedia USB 3.0 eXtensible Host Controllers are up to date. There are no exclamation marks in device manager.)
- Updating the chipset driver and bios for my motherboard from Asus' website.
- Disabling the "USB selective suspend setting" in power options
My guess is that the left 3.0 port is faulty and the entire front panel I/O needs to be replaced.
Or, there's a problem with the 20-Pin Motherboard Female to 2 Type-A Female Connectors Y-Cable (purchased separately since the 650D didn't come with a direct 20-pin connector for the front panel 3.0 ports).
Perhaps unlikely (and I sincerely hope this isn't the case), my motherboard is messed up.
I appreciate you guys for taking out of your own time to help me with this issue.
