Should i use 24GB: 4 x 2133MHz or use 32GB: 2x 2666MHz/ 2x 2133MHz & overclock (xmp) to 2666Mhz or 2133MHz

[ac88]

Hello everybody ,

 

i have an older build, an i7 6700K.

and i got 6 memory sticks laying around, all: Kingston HyperX (black) DDR4

 

4 of those memory sticks (24GB in total) are running at: 2133 MHz (stock)    -     2x 8GB / 2x 4GB   =   24GB TOTAL

 

the 2 other memory sticks (16GB in total) are running at: 2666 MHz (stock)     -    2x 8GB   =   16GB TOTAL

 

 

So now my question is:

 

Should i just use the 24GB (4 memory sticks) running at stock 2133 Mhz ?

 

or should i use 32GB which means:  2x 8GB = 2133 MHz  &  2x 8GB = 2666 MHz

and use XMP to run all 4 on:  2666 MHz    or perhaps run all 4 on:  2133 Mhz  ?

 

 

hope someone can help me with this...

Thankyou in advance,

Do you need over 16GB of RAM?  I'd use the 16GB of 2666MHz.

i actually don't! but it fills up all the memory slots on the motherboard / looks nicer and more complete/wouldn't have any other use for those memory sticks.

but i do get your point. 

 

but if i choose to use 32GB instead of 24GB so i mean:  2x 8GB (2666MHz) +  2x 8GB (2133MHz)  at stock speed: 2133MHz it shouldn't be any problem right?

since the other 2 sticks (2666MHz) will downclock automatically to 2133Mhz cause that the lowest speed ?

If you are planning on mixing 3 different kits of memory, just because you have the ability to put them all in your motherboard. I would recommend against it. Stick with 1 kit of memory that has the fastest speed. So the 2x8GB 2666MHz will probably be best for you.

its just 2 kits? 2

Just because you have 2x8 GB and 2x4 GB RAM sticks that all run at 2133MHz. Does not mean they are the same kit.

but thats not the question! 

 

the question was:  1 kit =  2x8GB (2133MHz)   +  1 kit  2x 8GB (2666MHz)   which makes 32GB

i was planning on leaving the 1 kit (2x 4GB) out! thankyou anywayz

Go for it. Your not going to break anything.

can i turn on XMP and overclock/run them all 4 on: 2666Mhz ?

or do you highely advice against it? ps: i dont know to much about overclocking memory, but i thought the HyperX versions would be easily overclockable since they do state it on their websites/product information etc.
