GA-X58A-UD3R r.2 + 3 x Kingston KVR 1333D3N9K3/6G what's wrong?

Question

motherboards

I can’t understand, Here is the gigabyte GA-X58A-UD3R r.2 motherboard ( www.gigabyte.ru/products/page/mb/ga-x58a-ud3r_20#kf), I studied the instructions ( https://ru.nodevice.com/ user-manuals/motherboard/g... and when installing memory of any capacity (I used 3 dice from different manufacturers and capacities) it is in the blue memory slots (in the photo) that the uterus does not see this particular memory, and sees the rest inserted into the white slots perfectly. Even if you set the 3-channel memory mode, he will see all the dies except those that are inserted into the blue slots.What do you think is the matter?
