MSI Z87-I Unlock Riser Card Support (Bifurcation) and Unlock Voltage Limit
#1
Hello,

I've got Msi Z87-I Mini Itx motherboard.
Bios version is 1.9.

Is it possible the enable the bifurcation support and unlock the 1.3V cpu core voltage limit? I know only Asrock supports bifurcation via their (beta) bios. X99-Z87-Z97-Z170 chipsets natively supports bifurcation technology and all Asrock mini itx boards support. (Z series and X99)

I've read some bifurcation threads on the internet and ask msi for possibility and they responded very quickly.

Sorry for my english. English is my not native language.

Dear HaypurTiryading,

Thanks for contacting MSI technical support.

Regarding your concern,as for this issue,since we haven't tested the bifurcation technology by passive riser card on this MB before,we cannot guarantee if it can work without any issue.Thanks and sorry for any inconvenience caused. 

Thanks for your cooperation in advance!

Best Regards,
MSI Technical Support Team"

Hi,

Any luck in figuring out how to enable Bifurcation. On my Msi bios on my X99a motherboard I found some settings with Amibcp under IntelRcSetup and IIO for turning on bifurcation. I havent been able to test it yet until I get a PCI-e two port split. Good luck.
