Hello, just a quick question. I just wanna check it here because it doesn't look logical. Basically in the manual it says that for dual channel I should install RAMs into 2nd and 4th(counting from CPU) slot for the best performance, or it's DDR3_1 and DDR3_2 slots as said in manual. Now what confuses me is that two channels are
Channel A: DDR3_2, DDR3_4
Channel B: DD3_1, DDR3_3. So that should be a typing mistake or something, but I can't be sure. What are they doing??? Anyway, do you guys know anything about it? Oh ye, here's a link to the manual page http://www.manualslib.com/manual/549876/Gigabyte-Ga-970a-D3p.html?page=16

Normally the black would be preferred (1-3 from CPU) as they are the lead slot for each channel, but with the size of many of the air coolers for CPUs these days, many mobos advertise to use 2-4 as the start point - it shouldn't matter 1-3 or 2-4

that's what they say

'' it is recommended that memory of the same capacity, brand, speed, and chips be used and installed in the same colored DDR3 sockets for optimum performance. For optimum performance, when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR3_1 and DDR3_2 sockets''

2 sticks should go in to the gray slots if the same as pictured at the newegg site

It's just that: Channel A: DDR3_2, DDR3_4
Channel B: DD3_1, DDR3_3. confused me because it would mean I would install it into two different channels according to that. Anyway thanks for confirmation, and would like to ask why is that recommended instead of installing them into black slots?

if black was performed then why do the say gray ? as shown and stated in the manual ?? you should explain that one out if you know better then the manufacture ??

I did not see any typo in all that

''when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR3_1 and DDR3_2 sockets'' according to the graph and pic of the board is gray, right ?

Dude... Don't you get it, from what they said above that DDR3_1 belongs to Channel B(one of dual channels) and DDR3_2 belongs to Channel A. If that was the case DDR3_1 and DDR3_2 wouldn't make a dual channel

The four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as following: Channel A: DDR3_2, DDR3_4 Channel B: DDR3_1, DDR3_3

yup that's what it says but its covered below that

I stated 'preferred' not 'performed', typically 1-3 from CPU are the lead slots for each channel by design and have been for years and years, and either set should work (1-3 or 2-4), many mobo makers have gone to suggesting (they say 'recommend') slots 2-4 as (to me) a bit of a psychological ploy to infer they have designed it with large coolers in mind as a convenience to the user and therefore is a better mobo - much as they do with other things and overt advertising, i.e. slight changes to the 1150 Realtek chipset for better sound output and then calling it another name, or things like claiming to use 'military grade' components. You see these ploys coming in many different ways, as mobo makers try and level the playing field, the use of 'Gaming' in mobo model names, the copying of the ROGs red/black mobo themes, much of it is playing up to and off of what already sells well.

Try it sometime and let us know what type of difference you see, they 'recommend' 2-4 for 'optimum' performance - they also 'recommend' 1-3 or 2-4 for 'optimum' performance (stated as same colored slots), somewhat contradictory isn't it? They state either or then narrow it down.

Regardless, the forums are a place to share information and knowledge. Manuals are generally for basic guidance to the uninformed. If we were to take everything in manuals at face value, as set in concrete rules, we would have no DRAM running higher than 1600, Intel K model CPUs would never be OCed, etc, etc....

If one wants to stick with what a manual says (go by the book) that's fine. On the other hand, they can also take in info provided from those that go beyond the basics. Many of us that do go beyond, are here in the forums and willing to share. That in part led to my article on the AMD vs Intel DRAM performance article:

http://www.tomshardware.com/reviews/dram-benchmark-fluctuations,4080.html

as well as my FAQs and Fiction article

With systems, there's always new things to learn ;)
