If your laptop is msi GT680, please go to this link, and enter you product S/N to confirm the chipset version:
Also please make sure your NB BIOS is up-to-date,(Depends on your GT680 version, at least newer than E16F2IMS.10E or E16F2IMS.30E) in order to display the correct chipset version in CPU-Z or the other applications.

For all the other msi Intel ® 6 Express Chipsets model, msi already applied INTEL B3 stepping to all of our new laptop products.

If you recently purchased another model, MSI guarantees that you will have no problems in regard to the old flawed Intel chipset and you can use your laptop worry-free.
