What Does the RAM Slot Color Coding on Motherboards Mean?

         

Yellow and orange, blue and black, inexperienced and pink: you’ll in finding the RAM slots on motherboards in all types of  coloration pairs. However what precisely do these pairs imply and the way does it have an effect on you when gadget constructing or upgrading your present rig?

Nowadays’s Query & Resolution session involves us courtesy of SuperUser—a subdivision of Stack Change, a group-pushed grouping of Q&A web pages. Picture courtesy of query asker, Totymedli. 

The Query

SuperUser reader Totymedli is curious in regards to the coloration coding of RAM slots:

I’ve at all times considered that the motherboard RAM slots are coloured in pairs, however by no means knew what it intended. I simply put the two RAM in, and after a number of tries it all the time labored. However after I attempted to put in a 3rd one it at all times throws me a blue reveal of demise. Is there an order how must I set up RAM to the board? What do the colours imply? Do they point out a efficiency raise probability or are they only a information for set up?

What’s the answer for his blue reveal set up concerns?

The Resolution

SuperUser contributor Enigma breaks the code:

It implies that the coloured pair is a twin channel set and that you simply must set up RAM as a pair to make the most of it.

You will have to set up 2 of the identical sticks as an identical pair on the identical colour slots after which any other 2 which can be the identical in the remainder two slots.

Ideally you wish to have to have all reminiscence be equivalent in a machine or else you are going to turn out with some reminiscence being doubtlessly downclocked (or voltage/multiplier) to the bottom fashionable denominator.

Sadly the colour pairing scheme isn’t standardized on older motherboards (extra up to date boards appear to persistently obey the colour-signifies-reminiscence-channel-rule, although).

In mild of that, Ecnerwal’s recommendation on the significance of checking the handbook in moderation will have to no longer be left out:

The colours are effectively answered by means of Enigma. As for:

However after I attempted to put in a 3rd one it at all times throws me a blue monitor of demise. Is there an order how must I set up RAM to the board?

The reply is Sure, there may be an order, and the main points are discovered to your motherboard handbook, which virtually at all times has special directions for what order the reminiscence slots will have to be crammed, and which configurations will work, so you could merely put it in as soon as and have it work, somewhat than:

I simply put the two RAM in, and after a couple of tries it all the time labored.

As in all issues associated to electronics and pc constructing, studying the handbook first and averting blue monitors of demise (or, worse, harmful hardware) is all the time most well-liked to trial-and-error. When unsure, reference the handbook.
