Titan X on HP Z840

[blankvisual]

Hello,

I just intalled a titan X on my HP Z840 and the workstation wont boot and beeps 6 times (gpu warning). The fan does not spin. I'm wondering how to diagnose this problem? Could it be that titan X will not work on my HP z840? I have a 1125w power supply which should be more then enough.

Please help,

Thank you

I have 3 Z840 with at least 1 Titan X in each of them. They should boot up with no problem. I had similar problem when I only connect 1 6pin to 6pin and 1 6pin to 8pin. Later I changed it to 1 6pin to 6pin and 2 6pin to 8pin and the problem is solved.

Thanks for your reply. My Titan x was defective, new one worked at first try.

Hi - how did you get the GeForce to work - I thought the Z840 only has 6 pin power and the GeForce needs an 8 pin?

I bought the Titan X (Pascal) and put it in my Z440. The Z440 has two six pin power cables just as the Z840 so i bought an adapter. So one six pin becomes an eight pin power cable. It works as ecpected and is cheap. No adapter is included with the card.

AFAIK it is possible to just use the two six pin power cable but i am not aware what the downside might be.

Thanks for the feedback. I am currently running a Quadro K5200 but I feel the new Titan will outperform. Its strange that HP only include 6 pin power supplies...

I used a Nvidia GTX 980 and the Titan X (Pascal) blew that card away totally.

I edit video in Adobe Premiere Pro CC and all video filters i use are CUDA accelerated, iow the graphic cards is important for great performance. I did a small test and this is the results and made me happy that i bought the Titan X (Pascal):

I use Pix4D to process drone imagery to create a variety of deliverables including point clouds, ortho mosaics etc.

No ones answered the question that the z840 only comes with one 6pin power cable avail. I have the same issue, so getting an 8 pin adapter still doesn't solve it for z840 owners who only have 1 6 pin avail. How did you guys who have a z840 get another power cable? Also, I have  a standard power brick that 800watts something and not the 1000plus. Will the Titan X pascal still work with my system? Thanks.

The Z800, Z820 and Z840 comes with two (2) 6-pin connectors. The second one is attached inside the chassis near the HDD´s in the frons side of the chassi and can be trixky to find if you don´t know where it is, but it is indeed there.

Yes, the card will work with the 800 watt PSU.
