Gigabyte 890GPA-UD3H Ram limitations

[MK1]

Any 890GPA-UD3H owners out there ? Notice a MHZ limit on the ram ?

 

I cant get my ram much over 900/1800mhz , as soon as it goes over 1800mhz speed I get the blue screen of death ..

 

Now I can run 7-8-7-18-25 all the way up to 900/1800 , and even with relaxed timings the result is the same once I go over 900/1800 ..

 

Now Ive used 2 different brands of ram , and the same result , just wont go over 1800mhz .

 

I contacted Gigabyte , and they told me its my RAM ?? [ Pish - posh ]

I think its the BIOS , the web site sais the board does not support ram over 1800mhz , but to affect overclocks ?
