Gigabyte Gaming 7 - C1 error | Tom's Hardware Forum
May 29, 2018 - What speed is the RAM set to run? Anything over 2133MHz on this motherboard is an overclock. Try lowering the speed. Updating the BIOS may help, several updates were issued to "Improve DDR XMP compatibility". ... I had this same problem with this same motherboard.

Help!!! Motherboard will not post Error C1 - TweakTown Forums
September 30, 2011 - Motherboard will not post Error C1 they should do rma,normally its first year with retailer then its direct with manufacturer,if you had mb tested then they would use different cpu,psu gpu and memory,since youve tested with other brands of memory and graphic card it only leaves your psu and cpu to test and a psu is quicker to test than cpu rma so i would do that sometimes a badly corrupted cmos or hardware detection problems can happen resulting in c1e error code plus other error codes and best way to be 100% sure is be patient and leave mb battery out overnight · Gigabyte z77x UP4-TH F11c Mo

r/buildapc on Reddit: Gigabyte Motherboard C1 Error - Won’t POST
December 20, 2020 -

I’m trying to upgrade my PC to an i7 8700k I bought a new motherboard, the Gigabyte Aorus Gaming 7 which supports z370 / LGA1151. I also got a new cooler, the Cooler Master V8 GTS, as I heard the 8700k runs very hot. The ram I’m using is Corsair DDR4 2400mhz. My graphics card is a 1080ti founders edition. When powering on, everything lights up and the cooler starts blowing and the led number counter goes through a bunch of letters / numbers before landing on C1 and then restarting. I googled around to try to figure out the error and some people mentioned it could be memory related, so I tried a different pair of sticks, tried reinstalling them, tried just one stick and still no dice. I’m at my wits end here. Any ideas?

December 5, 2021 - I have an old Gigabyte Z270 Gaming 7, MB and it's still reads C0 error code 'reserved' over 4 ago soo I wouldn't worry about as long it works who cares! Click to expand... It wasn’t working. It didn’t want to post with two ram sticks. Basically it were the 3 bent cpu pins. After 2 times of bending the back, I managed to get it working.

Estoy tratando de armar mi nueva PC pero cuando trato de encenderla, solamente muestra varios números y códigos y al fin muestra el error C1 y se reinicia, no me da imagen ni nada

Tienen alguna idea de porque pueda estar pasando esto? Primera PC que armó solo y no soy muy experto

Estoy pensando que pueda ser por el cableado de los ventiladores del AIO, ya que siento que no está encendiendo del todo, ya que no muestra ningún color

Hice varias pruebas con las RAMs pero sigo teniendo el error, serán incompatibles?

r/techsupport on Reddit: GIGABYTE C1 Error Code - Black Screen
July 18, 2022 -

SPECS: Mother Board: Gigabyte Z690 Aorus Pro ATX D5 CPU: Intel I7-12700k GPU: RTX 3070 Founders Edition RAM: GSKILL Trident Z5 5600hmz DDR5

Just a little background: The power in my room short circuited a few days ago, and I ended up having to re-download bios because of it. Not sure if this is relevant to the issue, but I wasn’t having issues with my computer until that happened.

I was playing games last night and my game kept crashing. Decided on restarting my pc because of a windows update. Upon download, now my pc display won’t show and my motherboard has a C1 code. I’ve tried the CMOS refresh to get back into bios, but no luck. Has anyone had this issue / know what it could be? I’m hoping my RAM sticks didn’t fry.

r/overclocking on Reddit: Gigabyte Z170X-SOC FORCE - C1 and C4 debug code.
November 29, 2019 -

Hi.

Unfortunately, the motherboard that I have died.

Which is a sad thing. Chipset literally died.

So.. I am going to buy another, the same model.

The guy, seller showed me a lot of pictures, and told me that If he put a single RAM(even 2133MHz) on the two left side of the RAM slot, it will somehow show C1 and C4 code and won't POST.

And if He puts a single RAM on the two right side of the slot, it will boot and show the OS Screen.

And C code is classified as "Reserved" Debug code in the manual.

What the heck is this thing? Can anyone help me to solve this thing?

  • The BIOS version is F20K, the newest(latest) one.

  • Tested CPU is Kaby lake Pentium G4560.

  • No bent CPU Socket Pins.

  • Seller tried to put all the same RAM to the all four slots, but no POST.

  • 5 beeps reported.

Gigabyte X58 UD7 Post error [Solved] | Overclock.net
August 24, 2012 - Tried clearing CMOS and even tacking the battery out, but still only the C1 post code. Has anyone had similar problem, will I have to flash the bios, if so, how does one flash bios on a duel bios MOBO with no monitor? ... Click to expand... Could be dead RAM slots. ... Click to expand... Nada :/ ... Hmm. x58 giga... pull battery, let sit overnight and retest. had a x58-ud7 rev 1.0 do the same to me. worth a shot.. ... ^^ Thanks I will try that. I need some sort of hope here. next step is talk to gigabyte,which could take a while I have flashed CMOS a few times and taken battery out, but both for only a few minuets so cross fingers, and hope overnight battery procedure fixes things

December 9, 2015 - Disable CSM in your motherboard BIOS, or you run the risk of getting a black screen at boot. For FTW3 cards, which you can flip the switch on the card to go to a non-ReBAR BIOS, you can quickly fix this and get picture again.

r/gigabyte on Reddit: Z890 Aorus Elite wifi 7 c1 error boot loop
December 24, 2025 -

Alright, I'm at my wits end with this one. I took advantage of a new egg deal recently to upgrade my computer:

Patriot Viper Elite 5 16GB 288-Pin PC RAM DDR5 6000 CL30(PC5 48000)

Intel Core Ultra 7 265K

GIGABYTE Z890 AORUS ELITE WIFI7 ICE

I built the pc and followed all the directions, but I cannot get it to boot. It enters a boot loop where it goes through multiple error codes, before finally ending up on c1, shutting off, and rebooting. I can't even get to the BIOS. The LED for RAM is lit up, but it switches between the CPU and the RAM light.

I have tried:

  • Reseating the CPU

  • Switching the RAM stick to the other slots

  • Resetting bios

  • Updating bios

  • Disconnecting everything and trying to boot

I am already on the second motherboard, RAM stick, and CPU from Newegg. I have already checked for bent pins on the Motherboard and I don't see anything.

I also have a MAG CoreLiquid A15 240 CPU Cooler on it and a 3060 GPU.

Here is a video of the boot process

SOLVED: It was the RAM. I took it to a local computer repair shop and asked if they had a stick they could test the motherboard with. Sure enough, they took my stick out and put the test stick in and the computer booted with no problem.
