If you look at the installation guide from the same download page, you will see images of many different boards with black RAM slots, blue and white RAM slots, and even yellow and orange RAM slots - some with adjacent pairs, some with split pairs.From 30 years in IT, here are the cliff notes why you should not mix them.Ī) nothing special as they work together because they are oem product from a identical production line and repackaged for retail.ī) the slower CL will slow down the other ram stick to permit dual channel processingĬ) they do not want to run in dual channel and will function fine but system utilizes them as 2x single channels ram sticksĭ) they don't play nice and system doesn't not bootĮ) they quarrel at times and will make your system lock up, blank your screen and make your sound got into a tiny loop sound crashing your game and/or your o/s and causing corruption of file as you rinse and repeat before admitting you truly should of bought a dual channel paired ram sticks. Then note on page 16 of your manual, you can see your board has blue and white slots and they are NOT adjacent to each other!!! As noted on the illustration on page 16, your memory needs to be installed as follows: So, Karabash, what you really need to do is ' RTFM' - read the friggin' manual! If you don't have it, you can download it from here.

They are labeled as DDR3-2, DDR3-1, DDR3-4, and DDR3-3 (blue, white, blue, white). On my Gigabyte GA-P55-UD4P, the slots are blue and white, but the like colored slots are NOT adjacent to each other. On this Gigabyte GA-Z77X-D3H board, all 4 slots are black, and are labeled as DDR3-4, DDR3-2, DDR3-3, and DDR3-1. And while many makers use different colored slots for the pairs, there is no standard for that either. So looking for A1 or B1 will not get any results - at least not with Gigabyte boards - which I use almost exclusively on all my builds.

There are NO INDUSTRY STANDARDS for color coding, labeling, or slot placement for dual channel (or triple channel) memory architectures. Click to expand.Forgive me for blending quotes but there are some significant misconceptions here.
