I run i9-13900KS on Asus ROG Maximus Z790 Hero with G.Skill TRIDENT Z Z5 RGB DDR5 32GB (2x16G)
My issue is that when I boot my PC, the mobo shows code 55 after a few boot loop. Sometime it's code 53. Holding the power button for a long time to force shut down it or switch off the power supply and then boot it back which bring it to safe mode always fixed the issue. This happen like at least once per day. Sometime, this also happen when I juz restarting the PC where after the screen goes black, it never boot back and after 1 to 2 min wait, u can see the mobo code 55 or sometime code 53. Someone, please help me. Although I can boot it back with this method, its very annoying when I don't know the cause of this issue. My guess was the armoury crate but I'm using Ryujin III and I need that shytty armoury crate anyway. Anyone know the cause and way to fix this ****** issue of intermittent code 55 and 53?
May I ask if the memory you are currently using is listed in the QVL?
Please try installing 1-2 memory modules in the channels recommended by the ROG MAXIMUS Z790 HERO user manual and trying to boot the system.
Additionally, please refer to [Motherboard] Common Q-CODE(Error CODE) and Troubleshooting for common Intel motherboard Q-CODEs and their corresponding troubleshooting methods.
Meanwhile, please confirm that you have updated the Intel ME to the corresponding version in the BIOS.
For example, the latest BIOS version of the ROG MAXIMUS Z790 HERO is 1202, which requires updating the Intel ME to 184.108.40.2066.
First, my memory is listed in the QVL. Second, My BIOS version is also up to date, 1202. [Motherboard] Common Q-CODE(Error CODE) and Troubleshooting is useless as it assumed as if the Error CODE that I kept getting is ALWAYS, which is not for me. It's intermittent. For the day, if there is code 55, I juz need to force off my PC, then the bios enter safe mode, then I press F10 to proceed and the code 55 will no longer happen for the rest of the day. That is until the next day after an overnight shutdown of my PC. Re-sit my memory stick and the CPU doesn't improve it as it works and boots as normal most of the time. It juz that sometimes it doesn't work on a weird condition where my PC is either hibernated or shut down for a long time and when I try to reboot after a long hibernate or shut down, code 55 happened. If I left it shut down for maybe 30 minutes or hibernate for 30 minutes, it still boots back normally. [Motherboard] Common Q-CODE(Error CODE) and Troubleshooting mentions as if my PC can't boot at all. The only thing that could be the culprit is Intel ME. My Intel ME is indeed not up to date. I'll update you on the outcome in 2 to 3 days as the issue of code 55 only occur as I mentioned. So, if within 2 to 3 days and it no longer happens, then we can assume it is the old version Intel ME is the culprit. Thank you.
Update: After the assumption that its old ver of Intel ME is the culprit, I stop blaming Armoury crate and proceed to update it. Guess what, it happens again after the update. lol. Is it possible for Armoury Crate to be the main issue?
Update: 6 August, it still happens again. What could possibly happen that causes this issue? Of course, I'm using the PC right now as I just need to force off by pressing the power button long time and press it again to make it boot from safe mode and enter the bios then juz press F10 to reboot and it works again. After that, again like I mentions before, PC run fine. Memtest also passed with flying colour. Stress test for both CPU, GPU, RAM, and all my driver also run perfectly. Can games for hours, and, if I shutdown and then try to boot again in like 5 minutes, it boot perfectly. However, if I shutdown and boot again in like more than 30 minutes instead, the 7 segments display on the mobo kept changing again and again for 1 minutes ++ and then stop at code 55. what the hell is going on? You all can say resit the RAM but it doesn't make sense to be hardware issue. Im very positive its definitely must be a software issue, else, how the hell can it run perfectly like how I'm using it right now to reply. I said this because I am very positive that someone will ask me to re-sit the RAM and CPU which I will definitely not entertained as its running fine right now. Please help me. I know I can still use it by force off it by switch off the PSU and then boot it back or press power button for long time then boot it back which will bring it to safe mode and enter bios, then press F10 and Enter which will boot it back normally. So yea, I can still use it if I kept doing this, but, this PC is custom build myself and I hate to see problem, despite it is petty, without knowing the cause. Please, Help... T.T
May I inquire whether the scenario you described occurred prior to any modifications? For instance, updating the BIOS or attaching an external device
Upon checking the QVL for the ROG MAXIMUS Z790 HERO, there are no records of a 4 x 16GB RAM configuration with a speed of 6200.
It is advised that you consult the memory purchasing and installation guide and perform a cross-validation by testing the memory modules listed in the QVL.
- ・When installing a memory kit, please adhere to the DIMM slot priority cited in the Memory installation section of the product manual.
- ・Ensure that all memory modules are from the same validated memory kit. Do not mix DIMMs from different memory kits—even if they are the same brand and model (e.g., two DIMMs each from two different memory kits). Mixing and matching DIMMs can result in a failure to boot and compatibility issues. In particular, the stability of a system with mixed DIMMs cannot be guaranteed when XMP (Intel)/D.O.C.P (AMD)/EXPO (AMD)/AEMP/AEMPII is enabled. For example, enabling XMP (Intel)/D.O.C.P (AMD)/EXPO (AMD)/AEMP/AEMPII to speeds above DDR5 4800MHz or above DDR4 3200MHz could result in an unstable system.
- ・The stability and compatibility of XMP(Intel)/D.O.C.P(AMD)/EXPO(AMD)/AEMP/AEMPII memory kits that operate beyond the POR standard is not guaranteed because it can be affected by the capabilities of the CPU’s integrated memory controller, installed devices, and the operating frequency of associated bus domains.
- ・Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.
- ・The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To set the rated speed of the kit, please select XMP(Intel)/D.O.C.P(AMD)/EXPO(AMD)/AEMP/AEMPII or apply manual settings.
- ・When installing total memory of 4GB capacity or more, Windows 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.
- ・DDR5 speed may vary depending on the number of memory modules used. In general, DDR5 speed with 2 DIMMs will be faster than that with 4 DIMMs, and its actual speed will also vary depending on platform. Refer to your memory modules' specifications for more details.
If I shut down my PC and I even switch off the power supply and wait untill all my rbg is off, then power back up and boot it, it boot smoothly. I repeat this for like 10 times. Then I even do memtest and it passed with flying colour. It just that if I shutdown and I boot back hours later, it causes code 55... how does boot back in a short period of time and boot back in hours later difference? Is there any differences that I may not know off?
Update after days of testing. I removed 2 memory sticks and run at 6200 MHz for 5 days and it always boot fine and never have boot issue and the code 55. Here is the peculiar part. I used my brother's Dominator Platinum 64 GB (4x16GB) DDR5 DRAM 6200MHz, run at 6000MHz. It failed the memtest, AIDA memory street test, occasionally causes games crash and sometime BSOD. However, I used it for 9 days and no boot issue including the code 55.
Please explained why my G.Skill Trident Z Z5 RGB DDR5 at 6200MHz (4x16G) which passed memtests as well as AIDA memory stability stress test do not failed when it run for 10 minutes and never crash my games nor do it causes BSOD, but will intermittently causes boot issue and code 55? But Dominator Platinum 64 GB (4x16GB) DDR5 DRAM 6200MHz, run at 6000MHz which is extremely unstable but do not have boot issue? Ofcouse, if I uses G.Skill Trident Z Z5 RGB DDR5 at 6200MHz with 2 sticks instead which is total of 32GB, it works fine and never have boot issue and code 55. I also reduce the the speed to 5800MHz despite it is rated for 6000MHz and it still causes boot issue and code 55 intermittently but the dominator which run on 4 sticks which is extremely unstable, again, I repeat, always boot perfectly without causing code 55. Please help me, I'm going crazy for this pass 3 weeks. What is happening? Is my G.Skill memory stick faulty? If it is, why it is very stable and all stress test never causes failure, heavy gaming never crash, memtests passed, and playing around with CPU and GPU OC and never crash due to memory but only causes issue when booting? How is that even possible for the RAM to be not ok ONLY DURING BOOTING? I initially assumed its due to CPU, but I resit my CPU and replace my thermal paste, and the result is just an amazing temp performance due changing the thermal paste with more premium one. Other than my CPU temp performance getting better, the code 55 boot failure intermittently still occur. 6200MHz, 6000MHz, 5800MHz, all 3 also caused code 55 boot failure but I can still trigger it to boot with the tricks I mentioned above, switch off PSU or hold the power button then try to boot again which bring it to safe mode, then it will boot like normal again. It does not make any sense. How could unstable memory stick boots perfectly everytime but stable memory stick do not? What exactly happen when my 4 sticks G.Skill boot failure? its stuck at code 31 for awhile, then code 5C, then code 53(sometime code 54) then loops again with other code then stuck at code 31 again for awhile, then code 5C, then code 53(sometime code 54) again, repeat for like 6 to 7 loops codes then code 55. Bruh... what is happening? If you need the video recording for the 7 segments code on the mobo, please tell me. I'll record it for you if it somehow helps you discover what is happening during the boot failure that causes code 55.
