Accessing memory speed 3rd gen i7

Recommended Posts

Posted · Original PosterOP

Hey guys so I have a i7 3770k and

A gigabyte ga-z68x-ud3h-b3 And I wanted to upgrade my ram so I checked the mother board comparability list and the one on intel arc an it turned out that 32gb of 2133 ddr3 was the Max this mother board can handle and figured that it should work out of the box


nope wouldn’t even post 😑

so I tried it with one of my old dims of 8gb 1333 and boom all set, but not that the speed I want, (I’m not sure if there is a serious down side to mixing and matching memory ) so I wanted to check the bios and immediately knew I was way out of my comfort zone..... 

When I checked the bios I found 

mb inteligente tweeter > advanced memory settings > system memory multiplier - i set it to 21.33 


then i shut down and swapped out the ram wouldn’t boot


would some one be willing to share there smartness with me 🙇🏻‍♂️

On that age of CPU and MB you need to use XMP to get to the speed that you want. 


However, ALL your RAM sticks need to support XMP in order for it to even show as an option in your BIOS (not sure if this is true now a days, but that is how it is with your generation of board and CPU). Remove the old RAM, install the new one and then look for the XMP setting in BIOS. If it doesn't appear then you should try to update the bios to enable it. 


You can of course do this manually with RAM overclocking, but if you have XMP use it as that is the much easier option.

yup this is going to be tricky. you need to tighten your ram manually and set manual voltage. Google ram overclock timing. Just because the board can do 2133, doesnt mean it can do that for all chips. 1866 is also a good overclock as well btw.

Luckily I had a good board with my 3770k. 32 gigs of 2400 dropped in just fine. Gonna be a headache working around with what you got now.
