Getting GA102 [GeForce RTX 3080] after adding the 12th GPU

Hi guys,

I’m getting the “error” GA102 [GeForce RTX 3080] when I try to add the 12th GPU on my rig:

MB → Asus Z490-P
RAM → 8 gb
OS version → [email protected]
DRIVERS → 470.86
POWER SUPPLY → 3x Corsair 1000W

2x M.2 PCIE adapter (full)
1x 1 to 4 PCIE splitter (full)
1x 1 to 4 PCIE splitter (1 card connected)

11 GPUs connected

Both the splitter works fine and if I use them alone with 8 GPUs plugged in they work

The problem begins when I add 2 USB to the second 1 to 4 splitter

I thought it was a power problem so I unplugged 1 card connected to the same power supply connected to MB and I powered the motherboard with two 8 pin cable (8 pin + 4 pin) but it started reading only 7 GPUS (don’t tell me why!?)

Have you ever had the same problem?

I see MB like mine with 15/18 cards connected and I can’t figure it out.

I’ve tried all the BIOS settings found in this forum (PCie SPEED, 4G decoding, etc.)

Thanks

splitters with certain cards are hit or miss.

I’m trying to add 1 rtx 3080 and 1 gtx 1660 super

Should I change the card?

Hola, soy de Colombia, una posible solucion es ingresar a la board, en modo avanzado, luego en dispositivos incluidos y deshabilitan la conexion LAN, despues inserta una USB Wifi y configura HiveOS para conectarse desde wifi, asi podras añadir una GPU mas, puede escribirme al correo [email protected]
