Asus z9pa-u8 MoBo gives code 69

xXLaraXx · Mar 26, 2014

Hi everyone,

I have recently purchased the parts to build my own PC, and got advice from one of the members here (see topic http://www.tomshardware.co.uk/answers/id-2058500/building-software.html).

So I have bought the parts (as given in the last post on that thread), including the motherboard of Asus z9pa-u8.

Now when I turn on the computer for the first time, the led indicator gives the code 69. The manual says 'Post code 69: Progress: NB Init'. So I am thinking that NB means NorthBridge, and it has something to do with the memory right?

I have looked up the compatibility of memory modules with my motherboard (see http://dlcdnet.asus.com/pub/ASUS/mb/Socket2011/Z9PA-U8/Manual&QVL/DIMM_AVL_List_Z9PA-U8_20131220.pdf), which gives the following option:

Kingston KVR16R11D4/8HC 8GB DDR3-1600 ECC etc...

I just checked my buylist, and saw that I have bought:

Kingston KVR16R11D4/8

It has been some time now that the PC is not doing anything and displaying the code 69, so I guess that the HC part is pretty important, and that I need to get new memory?

Is there any 8GB module (prefer a little bit cheap) on the list that you could recommend for my rig?

Thanks in advance for all the help!

Okay so that website also doesnt state the memory that I'm using.
Can someone maybe verify that code 69 indeed is a warning about the memory?

Thanks

I believe the Debug code refers to the NB DXE which checks the following...

•General purpose I/O (GPIO)
•Interrupt controller
•Timers
•Cache initialization (this could also be accomplished during early initialization)
•Serial ports, console in/out
•Clocking and overclocking
•PCI bus initialization
•Graphics (optional)
•Universal Serial Bus (USB)
•Serial Advanced Technology Attachment (SATA)

It could be your RAM but it could be your graphics card too. Try pulling your Graphics card, USB ports, SATA connections and try booting.

Okay I will try that when I get home this evening and keep you updated

Thanks so far

Hi, I'm Jewel with Kingston Technical Support and would like to offer our assistance. Part number KVR16R11D4/8 is compatible with your Z9PA-U8 Asus motherboard. It is not listed in our memory search since it has been discontinued. The problem is in fact the memory, KVR16R11D4/8 is Registered ECC memory which your motherboard does support but more importantly the i7-4770k memory controller does not support. You need Unbuffered Non-ECC memory, available part numbers: KVR16N11H/8, KVR16N11/8, and KVR16N11K2/16. For any further assistance, please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you. Please be sure to have the part in question on hand when you call.

Thank you for selecting Kingston as your upgrade partner.

Okay, So I have opened the PC, and pulled out the graphics card, disconnected the SATA and USBs.

Now when I have one memory module installed, everything seems to work fine. However, when I install the second one (in the second slot as indicated by the MoBo manual), then the PC doesnt start again, and the code 67 shows. It does not matter if I switch the two modules. It works for one module (whichever of the two), and when inserting the second one it gives 67.

For the Non-ECC memory, I am using the Intel Xeon E5 1620-v2 CPU (or does this one also use the i7-4770k memory controller). I got this memory especially since it has ECC, which was advised to me.

So kept on testing... With one memory module, and the SATA's, everything still seems to work (I find the HDD's and memory both in the BIOS).

However, when I have one memory module, the SATA's, and then connect the graphics adapter (AMD Firepro v4900), then I dont get any image on screen, and the MoBo code is 00. After some time it goes to the sequence of 04, 03, 02, 01, 00. Then it stays at 00 again. I have tried the VGA (MoBo) output, and all outputs on the graphics driver, but nothing...

xXLaraXx :

Do you have the PCIe Power cord hooked to your graphics card? Debug 00 is a tough one because it could be any thing from not enough power to your CPU to a bad motherboard.

As for the RAM is your slots on your motherboard color coded? Are you sticking the RAM in like colors?

So I found the problem with the Graphics Card. I had to set a jumper to disable the onboard VGA controller (see page 2-25 in the MoBo manual here).

The problem with the second memory module is probably the second slot on the Asus z9pa-u8 motherboard. I have contacted Asus, and they are willing to send me a new motherboard. For now, I am running with the second memory module in a different slot (which causes a loss of performance, as it will no longer run in dual channel mode). However, this loss of performance is relatively small (at least when I looked it up online), thus I will have the system running like this for now.

Thanks everyone for the help!
