I wonder if I have the chat transcript in my inbox..DAM I dont!!  

Ok so, on my last try, I didn't install any drivers of any sort.

I 

Then I removed the board entirely, reinstalled my intel board, filled the loop and now I'm playing WOW :)

I didn't try installing the specific drivers for the titan x BEFORE I put the card in, expecting that this would take place AFTER putting the card in, but without a screen.. I haven't been able to.

Probably best to start a thread of your own.  In that post, you would want to define the word "can't"

As a follow up to my own post, I contacted nvidia... all they could say was "buy intel next time.. good luck"

I gave the board another go with the chipset driver.  I installed a fresh full install of windows, only installed the chipset driver.  

Card still didn't work.

I called Asrock, and the nice guy asked me to try it out of the case.

Did that, didn't work

I put the card in the second slot, and low and behold, bios right away.

What I cannot say is why the card works in an 8x slot, but not the 16x slot.

The card performs great in my gigabyte 16x slot.

I dont have a ton of time to fiddle with this anymore and testing it is a real chore.  Further, I'm not even sure the performance would be ahead of my z170 board and 6700k.  I bought this on a whim just to give a kick in the tires.. i don't want it that badly

It's a mess.. you can see my titan x hanging there.  I have to slide the 460 in, connect to my old monitor.. i have video.  Take it out, put the titan x in the PCIE slot to my asus.. no video.

When I remove the 460, and install my titan x connected to my ROG, i get no video signal and can't do anything.

I'll paint a better picture.

I have my case. In it is my gigabyte and intel board, corsair ram, m.2 hdd, titan x, water pump and rad..  with tubes between it all.

Initially what I did was put my new x370 and ryzen chip on my on my test bench.  I installed an air cooler and my brand new gskill memory, along with a brand new samsung ssd hdd.  I used an older 750 watt psu and and my old gtx 460 card that I keep around for junk like this.

I booted it up on my old monitor, installed windows, got everything updated.... then comes the moment of truth.. time to put it in my case.

This means I had to uninstall the air cooler, clean the cpu.  Install my new EKWB ryzen waterbock on the cpu on the x370.

Then I have to drain the loop on my gigabyte board.  pull the radiator, pull the tubes from the cpu.

Then remove my gigabyte, install the x370.  reconnect the water tubes to the x370 cpu block, refill the water system, place all mobo cords (power, cpu power, case plugs, fans, etcc..) then crank it up.. only to find no output to my monitor.

Previously, I had fine output on my test bench.   So I turned the system off, and pulled the titan from the slot.  Since it's connected to the water loop, I had to just let it hang there while I slid the gtx 460 into place to see if I would get video output from that card.  which I did.

So I updated the bios, installed some nvidia drivers, and removed the 460, placing the titan back.. nothing.

So more info.  I have two monitors.  one old junky blue cable test monitor, and my asus rog 279PG.

The asus only takes Display port or HDMI.

My old monitor only takes blue.

My titan has DVI, DP, and HDMI out. 

My gtx 460 only has DVI out.  So wtih a DVI adapter to blue cable, I can run the old monitor on my GTX460.

However, the DVI port on my titan x doesn't match the adapter, so my only choice is to to run the titan x to my asus monitor via DP, hdmi or dvi to DP cable I bought from amazon.

So I cannot test the titan x on the old monitor, I can only connect it to the ASUS ROG monitor. .... and I can only operate the gtx460 on the old monitor, not the asus ROG>.....
