Hi All,

Just bought an Asus NVIDIA GeForce GTX 970. I'm having a very frustrating time installing it into my machine. Here's the deal:

When I connect the graphics card, the mem light on my motherboard flashes red and my monitors don't turn on - it just flashes. There's two DDR3 RAM slots that each have 8GBs. I remove one of those, and the system works. (the mem light goes away, monitors fire up, system works normally)

I also tested by putting the DDR3 back in, unplugged the graphics card and connected to onboard VGA - everything works well.

So the issue seems to be related to the GTX970 and the RAM. Some kind of conflict?

Not sure exactly what I should be doing next to resolve?

My system is:

Intel i7-3770 CPU @ 3.4GHz
ASUS P8H77 M LE
Antec 750 PSU
Windows 7 Service Pack 1, 64-bit

What do you guys think is going on here?

this is indeed weird. Maybe one of your sticks is faulty. not sure why it only comes to daylight when you connect a gpu tho.
You should run memtest anyway. run it without the gpu connected and run it seperately with both sticks one by one.

That's a great logical next step for troubleshooting. Ok, I'll try that and update this post on what's uncovered. Thanks!

I've managed to narrow down the problem to the right hand side RAM slot.

When there's a ram stick in there, the ram led light flashes red and the monitors don't turn on. When I put either of the two available 8GB ram sticks into the left hand side and run a memtest, it works fine.

So, it now seems pretty clear that it's the right hand side RAM slot conflicting with the GTX 970. Is there a way to resolve this?
