    Q-Code 07

    Help!

    I completed a new Ryzen 1700x build with the CH6. The system was fine and seemed to be stable. Was running at 3.9 everything was working fine. Went to bed got up the next day and system will not post. It is showing Q Code 07 and the Dram light is lit. I have tried removing my memory sticks trying with just one (in every slot), unhooked everything, reseating all power cables, etc. Purchased a new DDR4 kit that was on the QVL per Asus support(even though my trident Z sticks were working fine before/new sticks are Corsair). Still no go...Does anyone have any ideas about Q code 7. The board RGB LEDS light up fine and I have used the BIOS flashback to try different version (clearing CMOS in-between etc...). was on 0902 when it would no longer boot. Have tried 1001 and 1002. Also tested my PSU with a multimeter and it checks out perfect. Tried a different Video card as well (in both slots). I would appreciate any information...

    Q Code 07 presents it's failing RAM training.
    Try to swap different RAM modules for troubleshooting or
    back to 0902 and clean CMOS

    So I have an official solution for the Debug Error code 07 on post. YES it is a RAM related issue. I struggled with this problem for a week before I came to a realization. So let me tell you the trouble steps I took.

    So here's the issue I was running into:

    First, The specs of my brand new build:

    Ryzen 7 3800x
    Wraith Prism (Stock heatsink for the CPU)
    MSI MEG x570 Ace (Don't get me wrong, yes it's MSI but the debug codes I think are all the same)
    32GB DDR4 3600 G.Skill TridentZ Neo RGB (2x16GB)
    AMD PowerColor Red Devil 5700xt
    ThermalTake ToughPower Grand 80+ Gold 750w
    1TB Inland m.2 Gen4 drive
    Windows 10 64-bit Pro
    1st Bios to Newest Bios (tested each one for flaws/issues)

    The issue I was running into:
    As I built the system, I put my RAM into A2/B2 slots according to the Mainboard Manual specifications for Dual Channel operation. Hooking everything else up and turning the system on for the first time, the Debug LCD went through a variety of debug codes quite fast then paused at 07, went through more codes, stopped at 07 and the diagnostic LED for the DRAM next to the 24pin power port on the mainboard was on as well. System would not boot or complete the post.

    Steps took towards resolution

    I obviously did some research online for a week straight to find no help whatsoever in solving the problem. The advice I got from doing my due diligence and researching the hell out of the Debug Error 07 code, I found the below answers.

    It's a RAM issue, right? So it's OBVIOUSLY Bad Ram. This IS a possibility, but if you've already tried the below steps, read on. It was NOT my solution.

    RAM Issue: So swapped out the RAM, right? Of course I did. Did I check the QVL compatibility list for my mobo, Of course I did. 100% compatible.

    1) I tried swapping the ram from A2/B2 to A1/B1. STILL no post.

    2) I tried SWAPPING THE ram modules to A1/A2, HOLY sh*t It posted and booted no problems! Well, one problem existed now. IT WAS ONLY SINGLE CHANNEL!!!!! Which means my ram was running at 2133Mhz instead of 3600Mhz. This is a NO GO.

    3) Just for sh*ts and giggles and for further diagnostic testing, I swapped the RAM to B1/B2 slots, It's a Code 07 again with the DRAM Diagnostic LED on.

    4) The system had no problems or crashes or stutters running on A1/A2 in single channel, so I didn't think it was the ram, but the easiest resolution was to swap out the ram at the store, so I did. STILL the exact same issue. No Post/Boot and Code 07 with the Diagnostic LED for DRAM on.

    The DRAM diagnostic LED was still on, the Post code on the LCD display was still 07, no post/boot. Couldn't get past 07 or the DRAM led with the new RAM either or forced to run in single channel only, which was not gonna be acceptable.

    So if it's not the RAM and the mobo is having the exact same issue with the new ram in every step, it MUST be the Mainboard, right? It's a VERY Good possibility, but again STILL not the solution for me. Here's the steps I took for the mobo:

    1) I swapped out the mobo, plugged in all the cables. flashed the firmware using the Flashback USB port.

    2) I repeated all the steps in the RAM testing above with the new pair of RAM modules.

    I got the exact same results as above. So What the HECK! If it's not the RAM and it's not the motherboard, what else is there? It's a RAM issue, right? So it's gotta be EITHER the RAM modules themselves or the Ram slots on the motherboard are bad, right? Well, read on.

    After doing some more research, I discovered that the "MEMORY CONTROLLER" is built onboard the CPU of the newer Intel and AMD CPU's...

    Could it be? Could it possibly be that the Memory Controller on the CPU itself is bad and that is why the B-Channel of my RAM slots would never function and would prevent the system from booting/posting successfully?

    Infact, the answer to this question is YES!!! A Resounding YES!!!

    I swapped out my Brand new (week old) Ryzen 7 3800x with a brand new one exchanged at the store and all my problems are GONE!! System works flawlessly, I now have my RAM working not only at 3600Mhz but they're overclocked to 4400Mhz with no issues whatsoever.

    I know this is an older post, but it's one of the first that pops up on google and apparently this problem still exists from time to time, so I wanted others to be able to see it, whether you run a Gigabyte, Asus, ASRock, MSI board, etc...Hopefully I can help put this problem to rest for a LOT of people.

    Now granted, I speak of B-Channel slots only because that was MY case scenario. In all honesty, If the Memory controller of the CPU is bad/defective or goes bad along the way, It can cause any variety of RAM problems, such as BSoD's, crashes, memory errors, DRAM diagnostic LED and even post codes relating to the RAM.

    Fixed 07 Error Code

    On my board I got a 07 code when I had the Infinity Fabric too high. The bios reset in the back I thought would reset the bios entirely , it would allow me to get the F1 bios reset message but any attempt to reboot and boot to windows resulted in 07 again. Finally I tried reset the bios to optimized defaults hit f10 save and exit and that solved my problem, so if the bios reset button doesn't work for you try loading optimized defaults in the bios.
