i am using corrently with 16 gigs of ram and i wanna expand it to 24 gigs of ram ,but i cant when i putting more 8 gigs after the 16 gigs of ram my pc wont boot up and doing bip bip bip sound,
my corrently 16 gigs of ram mainfactor is hyper x 1.35v 8x2 1333Mhz
and my other is 1x8 kingston 1.50v 1600Mhz,
motherboard GA-H77M-D3H (rev. 1.1) brand new from the box,
i checked the 8x2 alone and it works but when i putting more 8x1 gigs my pc woont boot ,but when the 1x8 alone it works its only works alone. there is a way to combine them?. thanks for the helpers
 
Would need to know exact product numbers of both RAMs for more detailed analysis. But from what I see already, your chances of making them work together are slim. Your old ram works at 1.35 V, while new one needs 1.5 V - and to make them work together, both would need to work under same voltage.

Simply put, you cannot combine the two. Not only are the voltages different, but so are the speeds. It's as if you're creating a highway with one lane that as a speed limit of 100 km/h, and another two lanes with 70 km/h speed limit. It will not work, and it will cause a lot of traffic problems. That is what is going on in your PC.

Furthermore, triple channel RAM configurations are not recommended - try to go with either one stick, two sticks, or four sticks, never three.

I suggest you stay with the 2 x 8 GBs of DDR3 1333 Mhz RAM for now. If you want more, upgrade completely to a 32GB kit.
 
Your version of Windows might limit the amount you cnn use:
