Motherboard is CM6330_CM6630_CM6730_CM6830_M11AA ivy bridge H61

There are 1000s of threads inquiring about mixing memory. The best advice is to install matched pairs/sets.

Mixing sometimes works, sometimes doesn't.

its best in kiots

and pc3 -1200 8gb ddr3l 1.35v means nothing without the timmings which is usually ends in cl14 etc

to get the true name of motherboard

type

system information

tells the proper name of the motherboard.

all youve given us is

3 diffrent pcs names
CM6330

CM6630

CM6730

CM6830

are all diffrent models.

or open the pc and look for the actual name on the motherboard

The lucky part for you is ddr3 memory is very open to mixing sticks. It seems the magic of mixing memory is no longer workable with ddr4 or beyond or more picky with Ryzen's and a hit or miss with Intel.

It makes since as new system memory are so far above the 1333 or 1600 speeds the timing and frequency need to be tight.

ddr3 not so much to play nice.

Desktop Ivy Bridge cpu's support normal 1.5v ddr3 ram, there's no ddr3l requirement with any desktop cpu unless it's a laptop, so you won't damage anything running 1.5v memory.

Mixing ram can have its problems but it is less dramatic with ddr3 compared to ddr4 and ddr5. Ddr3l can also run at 1.5v and that's what the motherboard will default dram voltage to when mixing 1.35v ram with 1.5v. Won't work the other way, even if you could force it, i doubt 1.5v ram would be stable at 1.35v, you get what i mean.
