Understand What The Mobo Leds Indicate

DDR? NB? Significance?

It may look like I know what I am talking about, but I don't.

These MoBo lights come on during startup. They did not used to. Besides the other problems I am working on, some time ago I lost the "sleep" function and believe that there may be a connection. Of course, it may be a coincidence, or user observation error.

I was playing around over in the "Photo" thread and posed the question and scenario there. Instead of repeating my attempt at a comedic description, here is the link. There is a nice image of the LEDs there.

So that you can see what I am seeing, and short of trying to figure out relevant pages in the user manual here is a link to the MoBo manual. The illustration shows the row of LEDs in NOT very good detail, and one page calls them NB and another calls them DDR.

Relevant pages: 7, 22, 23

Can someone help me understand these?
(Please reply here, not over on Photo)

Thanks!

DavidGP, thank you for taking a look and your comments.

I really have to get un-obsessed with understanding what those LED really mean.
Looks like you recognize them as DDR/RAM voltage indicators.
Why there are 7 lights and 6 RAM slots is beyond me.
Why the MoBo manual circles the same lights and calls them NB in one place as well as DDR in another is also beyond my comprehension.

I recently yanked (oops, the dentist prefers the term "extracted"), er, removed three 2 GB sticks of RAM and put in three 4 GB sticks.
The system not recognizes 12 GB. (I wonder if I can stick the other sticks into the empty slots?)
The LEDs were lighting-up with the previous RAM as well as the current RAM.

As far as I know, I am not over-clocking.
I had the machine put together by Cyberpower and they messed up in a couple of places, and I have no idea if the BIOS setting are as they should be.
I just made new shots of all the BIOS screens (except for how to set the time and date) and put them into one of my photo galleries here in case I can get anyone to give the BIOS a look-over.

Anyway, no red lights...so I should probably try to let go of this issue and move on to others.

Again, Thank you.

I'm not an overclocker but by seeing your photos - in #9 and #11 there is that red warning about 'standard' might improve system stability. I would be tempted to switch to standard and see if any of the problems you 've been having ease off a little. Your system seems to have excellent capabilities so I imagine your frustration at it not working right.

 

While shooting the screen, I was so tempted to switch to standard and see if any of the problems ease off a little that I DID, but switched back in order to accurately present the system "as is" for smart people to look at.

I'm going to go switch it to Standard now!

Thanks.

 

I can't read your motherboard manual link as it's all sideways on my screen but I may download it. But- DavidGP was asking about overclocking. This usually involves increasing a multiplier for clock speed to cpu and/or memory and also increasing voltage to cpu/memory either/or. May be why your board has these led's - to monitor what's happening. Some people monitor changes when overclocking with software and changes are made in very small increments until the system becomes unstable then back off a little. I would download and print a good manual and study the changes each setting available in cmos/bios makes/changes to the overall operation.

 

The manual was sideways for me, too, but only the first page or two. I downloaded it because my PDF reader is more intuitive than that website's clunky navigation.

Here is the Gigabyte site page for the manual (Revision 1) in case you get that far.

I'll attach the latest startup lights...looks like 4 Freq. LED lights are coming on during startup now.
Maybe they are supposed to light up when starting like a car dash to show they are working. I dunno.

At least these lights aren't red - lol
