Hello,
I'm here to ask some help regarding a weird issue on my new setup:
1) Computer part list :
- Motherboard : ASRock X370 Taichi - RAM : G.Skill FLare-X F4-3200C14D-16GFX (2 x 8GB) - CPU : AMD Ryzen 1700X - CPU Cooler : Cooler Master MasterLiquid 240 (push/pull config) - PSU : Corsair CX650 - 650W - VGA : ASUS GeForce GTX 1070 - TURBO - HDD1 : Samsung 840 Pro SSD 120 GB - HDD2 : Samsung 850 EVO 250 GB - Case : Antec P8 - Case Cooling : 9 Fan
Everything is brand new except ssd 840pro and some fan. RAM is on motherboard QVL Motherboard is on RAM QVL
2) Issue description:
/!\ Everything in bios is set to default (no overclock or xmp settings for ram)
When I cold boot my computer, it stuck on Dr Debug code 54 and do nothing (no reboot/boot loop, just stuck on code 54).
Sometimes if I manually reboot it pass the code 54 and start normally. Sometime it cold boot normaly (very rare).
In general boot sequence is : - Cold boot : Stuck on code 54 - Manual reboot : Stuck on code 54 - Manual reboot : Stuck on code 54 - Manual reboot : Ok it boot and works fine
After that sequence, I can go into bios, windows and no issue. I can hot reboot everytime I want but if completely shutdown my computer it will be stuck on code 54 next time I will power it on.
3) What I've done :
- Clear CMOS (with button, jumper and removed the battery) ==> Nothing changed
- Tested each ram stick in every possible place (alone or with 2 stick) ==> Nothing changed
- Tested multiple bios version (2.00, 2.20, 3.00, 3.20) ==> Bug reproduced in each version but 2.2 seems to boot correctly more often but can be stuck at startup on code 54 like other bios version
- Modified VDDCR_SOC to 1.1, 1.2 and 1.3 and set the LLC to lvl 1 ==> Nothing changed exept better boot chance in 2.2 bios version but issue still present.
- To exclude faultly ram stick I did a long HCI memtest (3000 % on 16 process with 800mb tested by each process) ==> 0 errors :
- Intel burn test 20 pass with 8192 ram tested ==> No issue
- Test with custom bios settings (bios 3.20) : set geardown mode to on/auto bank group swap to disabled bank group swap alt to enabled proc odt to 60 ohms soc to 1.05 v soc llc level 2 dram volt to 1.375v and make sure the am4 boot training is set to auto
==> Nothing changed
- Test with fail_CNT 5/7/9
==> Nothing changed except no F9 error code when I cold boot with XMP settings on (but stuck on code 54)
4) Test request from ASRock Support TEAM :

1. Please store your current BIOS settings in a user profile in BIOS.Load default settings via F9. Load the XMP profile in BIOS, then set the DRAM frequency to DDR4-2400. Save via F10 and let the system boot, and do not change other BIOS settings for now. Memory modules should be in slots A2 and B2. Please test cold boot with these settings. |
==> Done, not working, issue still present

If this has no effect then it looks more like a physical hardware problem. It could be related to PSU, motherboard, CPU or a RAM module. For example a capacitor might not be charging fast enough. Or there could be a micro fracture in one of the components. Then when the system is running, material can expand a little bit and this can be enough to temporarily ?�close??the fracture. 2. Please test each of the RAM modules individually with a cold boot, and make sure that you keep the system powered off at least as long as you normally would. |
==> Done, not working, issue still present

3. Also test slots A2 and B2 with cold boot individually, one at a time. |
==> Done, not working, issue still present

4. If possible please borrow another PSU to test with. |
==> I had my old PSU from my old 2014 intel build (corsair CX600M). Tested with this PSU but same issue
ASRock Support wrote:
5. If possible please borrow another CPU to test with. Of course I can imagine this step might not be possible. |
==> Not possible :(
ASRock Support wrote:
6. Please remove the CPU cooler and the CPU. Place the CPU back into the socket. Close and open the socket lever a few times. Install the CPU cooler. If it is fixed by screws then please make sure that you do not overtighten the screws. Then please test again. This might sound a bit silly. But because (as you probably know) the memory controller is integrated in the CPU, contact issues between CPU and motherboard could also lead to memory problems. |
==> Done, not working, issue still present (I did it 3 times. My cooler use manual screw so it's impossible for me to overtight)
5) Conclusion
Now, I don't know what I can do and I need some help from ASRock employes or someone who have better knowledge than me of this kind of issue.
Thanks in advance for your help.
