X99-A II Failure to boot with additional RAM

[Bladeacus]

Hi all,

 

I am running Windows 10 Pro 64 bit on an X99 A-II motherboard with an Intel 5820K CPU

 

I recently tried to upgrade RAM from 16GB (2 x 8GB G.Skillz Trident) to 32GB, with an additional 16GB of the same RAM. 

Same brand, same timings etc.

 

Long story short, anytime I have more than 2 sticks of RAM installed, the system will not boot and displays error codes BD, BF, etc.

 

Steps I've tried -

• Confirmed the new RAM works by swapping out and installing in place of the existing RAM. No problems. System boots with new RAM only.
• Confirmed RAM slots on motherboard are working by moving the original 2 sticks of RAM into alternate RAM slots. System boots. Repeated with new RAM. System boots.
• Installed RAM in recommended configuration from the manual, and tried different configurations as I have seen another user comment this worked.
• Enabling and disabling XMP in Bios
• Increasing RAM voltage in BIOS
• Disabling Fast boot, disabling memory checks in BIOS
• Reseated CPU, made sure CPU cooler isn't too tight
• Confirmed latest update of BIOS is installed

 

I have searched and searched for a solution to this problem but have not found anything that works for me so far.

Has anyone else experienced a similar issue or have some insight on what it could be?

 

Thanks in advance.

Hi all,

this might make no sense but remove the 24pin and all cpu power connectors, so 4/8pins w/e you have in use.

make sure every cable is seated propperly in the plastic bit of the connector and replug 24pin and cpu power connectors.

 

sometimes when you connect a cable it can be pushed out of the plastic part of the connector.

Thanks, I will try that when I get home.

Yes.

 

I did with Sandy Bridge.

Had 3 computers using 2 sticks of 4gbs ram. Wanted to upgrade to 4 4gb sticks. Two out of three would not boot populated. All used Gigabyte motherboards.

I jumped through all hoops trying to fix it but in the end I had to get 2 8gb sticks for the 2 that would not boot. 

It was a flaw in the chip set and the one that did take the 4 stick had a higher version number. 

 

Since the motherboards were about 4 years old there was not point in contacting Gigabyte.
