Gigabyte C1 Code No Post Boot Loop - PCPartPicker
The only quirk I have noticed is if I switch the Dual BIOS to BIOS 2 (backup BIOS) the MB stays on with C1 code and does not boot loop. Unfortunately the RAM and MB are just past 30 days with Newegg. They have deferred me to the MFG for now. I am hoping the new Corsair RAM today will shed some light on the culprit. g.Skill is a suspect as I have read similar issues with other Gigabyte MB setups.

Gigabyte Gaming 7 - C1 error | Tom's Hardware Forum
May 29, 2018 - Both the Gigabyte and Corsair website show they are compatible. Any help would be appreciated. Thanks ... 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. Install one stick of ram into the black lane and see if you get into bios without errors.

Help!!! Motherboard will not post Error C1 - TweakTown Forums
September 30, 2011 - C1e is a memory related error,could be CPU memory controller error too but less likely,have you removed mb battery and left out overnight then put back and try? Tested with just one stick of ram in any white slot?

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?

Cycling through error codes, stopping at c1 and reboots. | Overclockers UK Forums
December 5, 2021 - After further fiddling with it, I managed to get it to boot, however only with 1 ram stick, each of them works separately in any slot, but as soon as I put both of them in, it shows the c1 error again ... 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!

r/gigabyte on Reddit: Z890 c1 error code
February 19, 2026 -

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/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.

EDIT 2: IF YOU GOT THIS STICK OF RAM IN THE RECENT NEWEGG BUNDLE: Patriot has responded on the product page: We’re very sorry to hear about the issue you’ve encountered. We completely understand your frustration and are here to help. Based on your description, the problem appears to be related to an IC defect.
