ASUS Maximus ROG VIII Hero Error Code 62

joebeem · Nov 28, 2017

Hello,

Thank you in advance for taking the time to read this post.

Earlier today I started having a very frustrating issue with my new PC (built myself). Specs and isse are described below.

Motherboard: ASUS Maximus ROG VIII Hero with latest bios
CPU: I5 6600k 3.5 Ghz
CPU Cooler: Corsair H100i V2 AiO Liquid Cooling
Ram: G.SKILL Ripjaws V Series 16GB (2 x 8GB) DDR4 2666
GPU: ASUS GeForce GTX 1060 6GB DUAL-GTX1060-O6G
PSU: Corsair AX760i
HDD: 1x Samsung Evo 960 m2 256gb (windows installed), 1x Samsung Evo 860 512gb (secondary drive), 1x Western Digital SATA 1 TB
Sound B* Ilaster Zx PCIe
nateck SuperSpeed 4 Ports PCI-E to USB 3.0 Expansion Card

I have had this setup running since early October 2017 and over this past weekend (Friday, 11/24/17) thought it was a good idea to do some light overclocking.

I truly regret doing this now, but hindsight is 20/20 and given my setup is ideal for overclocking, I thought it wouldn't hurt to try. This is not my first time overclocking, but I am not an "expert" per se.

I followed guides directly on the ASUS ROG website and had overclocked my cpu to 4.3 ghz. Per the guide, I manually set voltage at 1.35. I VERY closely monitored the temperatures of the chip and they never reached above 55C at full load with stress testing. It would typically idle around 28C, which from my understanding, are pretty decent temperatures.

I also did some minor GPU overclocking briefly, (didn't add voltage), saw very minimal gains, and just set everything back to default using MSI Afterburner yesterday 11/27/17.

Earlier today, while watching a YouTube video with multiple tabs open in Chrome, my computer completely froze. That is, I couldn't move the mouse, no response to keyboard commands, had to do a hard reset. Upon restarting the PC, as Windows 10 was loading, I received a BSOD with Error 0xc0000001 "you'll need to use the recovery tools on your installation media. if you don't have any installation media contact your system administrator or pc manufacturer." It would essentially BSOD every time windows would try to load regardless of it were in Safe Mode or any type of recovery environment.

I could still get into BIOS just fine earlier and set everything back to default, but still got BSODS. After doing some research, I started to try to eliminate things that might be causing them... started by disconnecting external devices, then removed my ASUS GPU 1060, and finally took out one of my sticks of ram.

Upon trying to start with one stick of ram, using on-board video card, and every PCIe card taken out, I could no longer POST and my ASUS motherboard was showing a Q-Code Error 62 with the VGA light on, which seems to mean "INSTALLATION OF THE PCH RUNTIME SERVICES".

The monitor is just a blank black screen, doesn't detect any input.

I tried clearing CMOS multiple times, tried the Asus Bios flash utility to reflash the latest bios, and no matter what, I cannot get past Error 62. I tried different monitors and cables as well just for the heck of it, but with one stick of ram (tried seating in every available slot as well) I still could no longer POST. Finally, also just tried flashing the previous version of the motherboard's bios (3501) using the USB port on the back, but same error 62 result.

My assumption at this point is that it is the processor or possibly the ram. I really hope it is not the motherboard, but before buying new parts, I thought I would ask for another opinion here.

Thank you

Hi joebeem

Qcode 62 is a memory training error, so something is wrong with RAM or GPU. The orange VGA_LED could also mean a GPU malfunction and the LED on constantly verifies this. As you have iGPU then remove the card and see if that works.
Try with 1 module in the first slot and switch them around in case one is failing.

It is possible your Bios is corrupted as can happen using Windows Overclocking apps and should only be done using your Bios.
Are you able to access Bios?

joebeem · Nov 28, 2017

I am not currently able to access BIOS at all.

Upon trying to turn on the computer, the motherboard receives power, but I receive the error 62.

I believe I see the orange DRAM led that you are referencing, but it is actually solid white when error 62 is displaying. The orange led is on briefly prior to the white led VGA LED and this is the one that stays lit. There is also a red cpu led that turns on briefly, but again while 62 error is displaying, its only the white vga led.

I actually did my overclocking using bios and did not use any windows applications to do it at all.

I also used the ASUS port on the back to reflash the most updated bios and even tried a prior bios, but still get 62 code. Would this method fix a corrupted bios? I am assuming it would since it says that it reflashes the bios, but I am not 100% sure.

I also just tested the ram as suggested, but still error 62. Finally, I removed the GPU and tested with iGPU, but same result.

Thank you.

MeanMachine41 · Nov 28, 2017

OK so you reflashed the Bios. How do you know if the reflash worked.? As you can't get into Bios.

To recap on flashback Installation. Just checking as this can go wrong.

Latest Bios file is 3504.
Your USB must be formatted to fat32 and empty.
Bios file is renamed to M7H.CAP
With system powered down, USB is inserted into correct Flashback port on IO panel. As per port 6 (page 2-13 in the MB Manual)
Flashback can take a few minutes, so wait for blinking light to stop.
Remove USB and reboot.

BTW: On your MB only LEDs that continue to flash are a problem. Also check that the Qcode is actually 62 and not b2 as they mean different things. 6 will be drawn with a horizontal line across the top of the hex display while b looks like b

joebeem · Nov 29, 2017

Hi there,

Thank you for replying.

I reflashed the bios per the instructions in the manual using the flashback feature that you alluded to.

I formatted the USB thumbdrive to fat32, downloaded 3504 bios, renamed it to M8H.CAP (per the manual), and placed it on the root of the drive.

After inserting the usb thumbdrive into the port above the bios button, I pushed the bios button until the light started to flash blue. It did this for about a minute or two and then stopped. My assumption at this point is that it flashed the bios, but you're right, I do not know if it truly did or not. Based on the actions performed vs. the expected results in the manual, it seemed like the process was working. I tried this with 3504 bios and most recently gave the 3501 bios a try.

It for sure is a 62, not a "b2", but I have taken a picture and a video of it and they are at the links below.

Regarding only flashing LEDs being an issue - my pc currently does not have any flashing led's. The red cpu led comes on briefly followed by the orange dram led, but they both turn off after split second. The white vga led lights up and stays lit. Unfortunately, I do not recall if it did this when the computer was working or not, but for some reason I think it might have.

I have tried to boot it with only the processor, one stick of ram, and a few different keyboards and I am stuck on this error.

I am open to any other suggestions and thank you for taking the time to read this.

Do you think buying new ram to test with is a good idea or a new processor?

MeanMachine41 · Nov 29, 2017

From your description it would seem the Bios update was successful as the light stopped flashing and you went thru the correct procedure. (normally it will stay lit if unsuccessful).

It is at this point that I would be looking at swapping out the RAM modules or having them tested in another system. If they prove OK then the only other thing I can think of is the CPU. I say this as you OCed and then Qcode 62 error appeared whereas the system was OK prior to you Overclocking. You may indeed have to RMA your CPU unless you have a better response at ROG Forum. I viewed your thread and you may hopefully get a better solution.

I do know that some keyboards can give this error in a new build however you have had your system running for some time so I don't think that would be it.

BTW: Did you finish up checking your iGPU.? To eliminated that possibility.

joebeem · Nov 29, 2017

Thanks for the reply.

Yes, I tried everything using the integrated Graphics Card. I am still getting error 62 with every single component disconnected EXCEPT the CPU, CPU Cooler, one ram stick, and a keyboard. The fact that I cannot get it to post even with the integrated GPU worries me a bit as my initial thought when this issue started was that it was my Nvidia GTX 1060. I had hoped the iGPU would "rescue" me, but to no avail.

I was looking through the manual and located the MemTest button above the LEDs. I will research the functionality of this button, but is that worth trying?

In the meantime, I just ordered ram and a new CPU and hopefully will arrive today. I guess if the Ram nor CPU work, then the only possibility left is something with the board itself, right?

Thanks again.

MeanMachine41 · Nov 29, 2017

MemOK is a rescue tool for memory boot compatibility which can help the system to boot up. It is used prior to Post to enable a tuning profile but doesn't always work.

Hopefully the RAM or CPU is the fix. Good Luck.

joebeem · Nov 29, 2017

Thanks.

Just to update, it turned out the ram arrived today, but the CPU will actually arrive tomorrow. I tested the new ram and tried starting the PC and unfortunately I am getting the same error 62 and solid VGA LED. Tomorrow will be interesting as the CPU seems to be one of the last things I can try. Hoping for the best.

If there are any other suggestions, I am open to anything at this point.

joebeem · Dec 4, 2017

I just wanted to post an update.

After replacing the CPU with an i7 6700k, the problem was MOSTLY fixed.

If you are asking why I replaced my i5 6600k with an i7 6700k, its because I figured if I was getting a new chip, I might as well upgrade it since I had gift cards. The QCode 62 and VGA LED issue completely went away and as relieving as that was, I am now facing a new error

.

When the computer initially booted up, I was getting a Q-Code Error CC when I have both of my ram sticks in slots A2 and B2. After some research on Google, I tried taking out both ram sticks and just trying one in every slot.

I CAN SUCCESSFULLY boot the computer with no issue when my ram is in either slots B1 and/or B2. While I guess I should be happy that my computer is working again, it just annoys the heck out of me that I am now no longer able to have dual channel ram because when Error CC appears, the computer DOES NOT POST.

If I place a stick of ram in A1 and/or A2, I then receive an error code 55. After some more research, the only information I am finding is stuff about over-tightening the CPU cooler or there being a short somewhere.

To summarize, I have 2 x 8 gb DDR 4 ram sticks totaling 16 gb, but I am now limited to using one 8 gb slot in single channel by placing it in slot B2 or B1.

Does anyone have any possible insight of things I can try? I tried clearing CMOS again, tried reflashing the latest bios, but seems I am now stuck with this issue.

I know that dual channel is recommended over single channel, but is there a significant difference if I were to get one 16 gb stick and run it single channel vs having 2x8gb sticks? I primarily use this computer for gaming and use it with Adobe Photoshop, etc... nothing extremely CPU intensive.

MeanMachine41 · Dec 4, 2017

Hi once again joebeem

Glad to hear you're having some success. Obviously your previous CPU was the issue.

Qcode CC is an undocumented error code so not much help there. Qcode error 55 is no RAM installed so either you have a mismatch or either there is something wrong with your RAM or the MB RAM slot.
Very often the issue can be contamination in the RAM slot or modules not seated correctly.

Let me do some research and tell me the exact Part No of the RAM you are using?.

The i7-6700K has an official supported rated frequency of DDR4-1866/2133MHz so if you're using anything above 2133MHz then that is considered OC RAM and you may have to manually set your Timings and Voltage in Bios as any XMP profile may not be recognized.

First clean the modules with Isopropyl alcohol and blow out the slots with compressed air from a cannister in case of contamination (Do this only with the system completely shut down) and ensure the modules are seated correctly and in the correct slots.
There can be significant improvement in bandwidth/performance wise between single and dual channel especially with memory intensive applications, so let's hope we can get your RAM operating in dual channel mode.

BTW: Your modules should be inserted into slots A2 and B2.

joebeem · Dec 5, 2017

Thanks for the response.

I currently have this ram: G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2666 Desktop Memory Model F4-2666C15D-16GVR

https://www.newegg.com/Product/Product.aspx?Item=N82E16820231892

I just assumed that since it worked without issue on my i5 6600k, that it would / should work the same on my i7, but if I understand correctly, this is not the case?

I will try cleaning the ram and blowing out the system while it is turned off. When the ram was placed in A2 and B2, it would give error code CC, but I will try cleaning and try again.

MeanMachine41 · Dec 5, 2017

I checked the MB QVL and although your modules are not listed, they should work. Modules the same as yours but in a 4x4 configuration have been tested, just not 2x8.

G.Skill Ripjaws F4-2666C15D-16GVR are primary timed at 15.15.15.35 @ 1.2V with XMP2 however your XMP may not work at 2666MHz. It may require some manual Bios changes to these timings.
I have found slight loosening of the timings, a 2t command rate and a slight increase in DRAM voltage can help.

If you can't get them to work then contact G.Skill for advice. I doubt ASUS support will give you advice but the ROG Forum may help.

Edit: There is a MEI chipset version 11.7.0.1040 available at ASUS Support. I don't know for sure if this will help. It is the Management Engine Interface for better system stability and I recommend you update if not already done so.

joebeem · Dec 5, 2017

I can say for 100% certainty that these ram sticks worked prior to the issue I had with my processor (i5 6600k) at 2666 MHz too using XMP profile.

It was after installing the new processor i7 6700k that I started having memory code errors. I just wanted to clarify that since I don't think I was very descriptive.

I have a feeling that there is an issue with the board itself. I am going to try cleaning it still, but would this be a good time to try the "MemOK" button? If I understand the function of this button, I am guessing it is worth a shot.

Thank you for taking the time to help me out. I don't know if my huge essay of a post scared some people off, but you are the only person that responded to any of my threads on the various forums I posted on. I understand my issue may be unique and maybe others haven't even seen my other posts, but just wanted to say Thank You.

MeanMachine41 · Dec 5, 2017

Your Welcome joebeem

I'm sorry I could not put my finger on the exact RAM issue however my research tells me they should work and at their rated frequency.

The MemOK button is used for memory tuning. It may work so try that, however it will also set your Bios back to default so have that in mind if and when you Overclock the CPU.

joebeem :

I did not understand the problem itself as it is something I have never faced, so I left it to MeanMachine as he is more experienced in this type of stuff. Perhaps others might have done the same.

I hope your issue gets resolved, I hate when my PC runs into problems as well.

Oh, I am sorry, I didn't mean that as a "knock" against anyone. I was just thanking him for helping me out and I meant even on external sites where I posted this issue, I didn't get any responses lol. Maybe I need to shorten my descriptions or something.

joebeem · Dec 5, 2017

MeanMachine41 :

After this fiasco, I think if I am able to get my computer running the way it was prior to the processor issue, I will be happy. My overclocking days were short lived and I am not sure if I'd dare to even try it again haha.

joebeem · Dec 7, 2017

I just wanted to update in the chance that anyone in the future happens to have a similar issue.

I cleaned out the slots as well as the ram and received error CC again when both sticks were installed.

I have an identical pair of ram sticks and tried placing all 4 x 8 gb sticks to give me 32 gb of memory just to try it out. At first, it seemed like a light of hope as it gave a new Q Code Error 49, but it would not post after clearing cmos and using the memok button. Actually, after pushing the MemOK button with all 4 sticks, I received the Q Code Error CC again instead of 49 as I originally had. I am only mentioning it in case it means something to anybody reading this. I did a quick search about 49 code and it seemed to be memory related unless I am mistaken.

I also did some more investigating on Q Code Error CC which is undocumented, but everything that I have found related to that code and Asus boards relates to over-tightening the CPU Cooler and it having an impact on the circuitry to the memory. It seems I made a mistake in using a screwdriver to tighten the screws on the CPU Cooler if that is in fact the issue. I don't personally think I over-tightened it, but I can't say for sure.

Perhaps trying to reseat the processor and CPU Cooler one last time before tearing it all apart is worth a try.

The only thing I have not tried yet with this ram is to try manually setting voltages and timings. I never had to do this with the i5 processor, which keeps me thinking something is messed up with the board, but I'm more than willing to try it out. In the meantime, I ordered a replacement board so I can hopefully try to reassemble this weekend as a last resort.

However, if I were to try manually setting voltages and timings, would I do that with one stick of ram first (since thats the only way I can POST right now)? I am going to assume yes, but wanted to check here first in case the process should should take place with both sticks of ram installed.
