Can Intel DB75EN Motherboard Support 667 MHz 8 Gb x 2 RAM sticks?

Solution
The 8 GB modules might work together with the existing 4 GB modules. This is dependent on whether respective module characteristics (apart from voltage, frequency, and timings) are similar enough to allow inter-module compatibility. The only way to be sure is to test them. Some adjustment of settings in BIOS may also be required to help the modules work together.

Also, to maximize memory bandwidth, the recommended configuration of memory is to have the same (total) memory capacity in each channel. So there should be an 8 GB module and a 4 GB module in each channel (making 12 GB per channel) making a total of 24 GB of system memory.

The first two memory slots form the first channel, and the last two slots form the second...

Hey, Thanks for the prompt reply. Apologies it took a bit to find out this info using CPU-Z.
The Mobo DB75EN has Intel Core i5 3470 (Socket 1155 LGA) @3.20 GHz CPU.


As for RAM, these 2 sticks are currently on another system, which i need to insert into above Mobo upon migration.
RAM Stick info:
Module size: 8192 Mb
Max Bandwidth: PC3-10700 (667 MHz)
Manufacturere: G.Skill
Part Number: f3-10666CL9-8GBNT

Hey Thanks for the reply, can you check my reply above?
 
Thanks for the extra details.

Presumably the G.Skill memory is actually part number F3-10600CL9S-8GBNT, since there doesn't seem to be a part number F3-10600CL9-8GBNT.

The G.Skill memory should be compatible due to matching memory chip densities. However, as this memory part number is a single module, and you are wanting to use two of these individual modules, there is a possibility that these two modules might not be compatible with each other (due to variances in characteristics of modules, even for modules with the same part number). So be prepared to try several other modules (with same part number - F3-10600CL9S-8GBNT) until an inter-module compatible combination is found.

Alternatively, and a better option is to get a 2 x 8 GB dual channel kit instead, where inter-module compatibility has been tested and guaranteed to work. This could save a lot of time and money instead of trying to find compatible individual 8 GB memory modules.

Actually i just checked, the DB75EN board already has 4GB x 2 RAM sticks with the same frequency with part number
F3-10666CL9-4GBNT
already installed it. Does that mean the 8GB x 2 sticks will also work fine?
What if want to add 2 8GB sticks and 1 4Gb stick which has same 667 MHz frequency and same brand?
Sorry if i sound like a noob, as an artist all this is a bit more technical to me.

The first two memory slots form the first channel, and the last two slots form the second channel.

The 1 GB module might be compatible with the other modules, but again this depends on its' characteristics. In any case, if using two 8 GB modules and two 4 GB modules, then all four memory slots will be occupied, so the 1 GB module can't be installed.

Wow, This is wonderfully informative, I thank you for this info.
Sorry my bad, there's no 1 GB stick, i was talking about 1 stick of 4GB, but i understood all.
I'll have paired a 8Gb+4gb stick one channel and same in another channel making it 24GB total. I will post my findings for information purpose in a few days when i make the change, possibly after Sunday.
Thanks again!

Hey, Just wanted to confirm that it worked perfectly.
I now have:

Intel i5 3470 @3.2GHz with Intel DB75EN board (Previously DH61WW with Intel i5 2320)
Samsung EVO 850 SSD (250 GB)
24 GB RAM >
> 2 x 4GB DDR3 memory sticks (G.skill) (PC3-10700)
> 2 x 8GB DDR3 memory sticks (G.skill) (PC3-10700)
Nvidia GeForce 750 Ti OC

Thank you so much.
