Unfortunately you have to reflash your laptop. I faced the same issue and had to do it. You could either ask a local service to reflash or do it yourself, the total price of the equipment will be around ~$7. The procedure is quite quick and simple, just be careful. Follow these guides:

Here is my BIOS https://drive.google.com/open?id=1BhVy4PSOsJJjoShwD-ggZ_3VCIdGhIF-

Disclaimer: I can’t guarantee that it will work for your laptop version. In this case you should ask for a BIOS dump here or somewhere else (using your current dump makes no sense because it is already corrupted).

Hi, guys. I also had 1066 mhz issue but fixed it somehow playing with BIOS memory options, look at pics.

AIDA’s tests now shows 8/9 Gb/sec R/W speeds vs 5/6 before and latency reduced to 125ns from 150-170ns.

As for drivers etc. What I did: made drivers backup, then clean install. Plugged ethernet dongle to update windows – this should install drivers for some unknown devices and wifi too. You may update wifi driver manually from saved backup, not sure what device exactly (they all same under Unknown section). Then installed chipset driver pack https://www.google.ru/search?q=socpackage_cht_intel_win10_64_ver103 from this file.

After that you need to install (from backup):

Intel(R) Battery Management Device – for battery levels.

Realtek Bluetooth UART Bus Driver – bluetooth.

ES8316AudCodec Device + Intel SST Audio Device (WDM) – for audio.

Hope this helps.

 

BUT! I have minor touchpad issue. It’s too tough for me (after Chromebook’s soft and sensitive), especially two-finger scrolling. Any ideas how to increase sensitivity (or decrease scroll threshold)? Modifying Windows’ options didn’t help.
