Hardware projects / Z800 3x GPUs
Last post by Mate Steinforth - February 27, 2018, 07:47:52 am
Hi there,

I'm using a Z800 Mainboard with an adapter cable on a standard 1200W Power supply. I want to install 3x 980ti GPUs in the machine, but the one in Slot 7 always gives me an error 12 ("not enough resources") in windows.

It does work as a single GPU in slot 7, but when I add even one other GPU, it throws this error. I can use two GPUs in the assignated PCIe slots, but I need three to work.

I played around with disabling everything I don't need and PCIE Adapter/Compute Settings in the BIOS, but to no avail.

Thanks,

::mate::

Thank you  for your advices about  the fan  connector. Maybe we have different definition of the first pin .May be we just counted from opposite side.

Dear hen6e

don´t use your fan (6 pin) without changing the connections pin 5 and 6 and 1.

You could kill the mobo, I had it 5 min switched on and it was very "warm" in the near of the fan.

I have 1 and a half running systems.
During the first switch on was the same problem like Z440 Mobo,
no screen , boot precedure stopped with memory error.

But the A99-a has a very nice manual and I was able to make
a bios update.... The system runs stabil. I was happy to use my
reg ECC DDR4 2400 RAM. Installing Windows 10 64 bit with USB-Stick
where without complications with the ssd corsair MP500 240 GB.

first:
Motherboard Asus A99-a
Intel Xeon e5-1620 v4
Cpu fan noctua 14cm
Ram Kingston reg ecc KTH-PL424 2 x 8 GB
Corsair MP500 240 GB SSD with adapter for m.2 scsi
Monitor lg 43ud79-b
Pny quadro p1000
Power supply atx 550W
ATX Tower (old)

half system for selling or storage:
Power supply for z440 tested could not find any mistakes
Motherboard Z440 (no idea to flash the bios because no manual)
adapter for ssd
Tower Z600 (empty)
Adapter for Z420 Mobo 24 pin to 18 pin
2 connectors 12 pin

Thank´s all for the interest. Excuse me for not supporting you in reading
the power supply ID, I don´t know how.

Cpu fan 6-pin connector

If pin 5 would be RPM for second fan
If pin 6 would be PWM for second fan

It would be not the best idea to connect with pin 1,

May be it's better leave pin 6 and connect pin 3 with pin 5

I try to build a working place for autocad and 3d studio max.

My first idea

Motherboard z440
Intel Xeon e5-1620 v4
Cpu fan noctua
Ram Kingston reg ecc KTH-PL424 2 x 8 GB (one bank1 one bank 8)
Corsair MP500 240 GB SSD with adapter for m.2 scsi
Monitor lg 43ud79-b
Pny quadro p1000
Power supply atx with adapter

First change (because of don't found the right adapter)
Power supply for z440

Second change
Motherboard asus x99-a
Power supply atx
No adapter for ssd

I hope next week I will be ready for work.

Do you  use  reg  ecc  ddr4  memory? It  seems that only this kind ram can be used on  the board .

I am not sure if the connection of 651 of fan connector is right.

Your pin descriptions could be right, but I am not able to organize a oscillograph.
This 11V pin (old) is z440 the only one connection to the power supply with 5 V.

I will change the mainboard because of defect. That's why I have a power supply for z440 available for 145 GBP + delivery costs, sombody interesting in buying?

As I have learnt, the p1 connector pinout should be as shown,but I need your confirm.
The 10、1 Pin is output for 5V equipment like sata from VRMs on the motherboard.
The 16 pin is a POWER_GOOD signal,which trun to HIGH when the PSU finish startting period.
The 17 pin is a 5v stand_by voltage which is different from z420's 11V.
The 18 pin is a negative 12V input for RS232.
The 8 pin is PS_on,connect this pin to groung will trun on the PSU.
The 9 pin PSU_ID tells the motherboard which psu is installed ,it is different from standard ATX psu.
If you have oscilloscope or logic analyzer, please capture the waveform of PSU_ID.
Thank you!
