ASUS P5K + NVIDIA GeForce GTX 560 Ti

Yo, quick question—would it be a total disaster if I tried to slap an NVIDIA GeForce GTX 560 Ti into this ASUS P5K? From what I can tell, the motherboard is basically straight-up trash right now.

Running a Phenom 955 Black Edition
Got an OCZ 1 Fatality 550w PSU hanging in there
4 GB of RAM

If the motherboard can handle that CPU, I guess the GPU will be fine too 🙂

Yo, I’ve got a massive headache here. Every time I plug both 6-pin connectors into my card, nothing happens. My old CRT monitor is hooked up directly to the motherboard, and there’s just zero picture. Plus, sometimes the monitor starts making this constant, annoying "tick, tick, tick" sound. It's driving me nuts.

If I only plug in one 6-pin, the monitor actually works and the PC boots up fine, but obviously, it won't recognize the new card. Those red warning LEDs on the card stay lit, and I can't even get the drivers to install because the system isn't seeing the hardware properly.

Thanks!

If you only plug in one 6-pin connector, it won't recognize the card because there clearly isn't enough power. Don't try running it like that...

Make sure you plug in both 6-pin connectors. Then try booting into Safe Mode and manually adjust the resolution there... I honestly think the issue is just that the card is defaulting to a resolution your monitor can't actually handle...

Either that, or try borrowing an LCD monitor. You could even attempt hooking it up to a TV screen... then just install the drivers and tweak the resolution settings to match the CRT.

It would also be worth trying to plug the monitor directly into the graphics card rather than the motherboard (since you're currently running on integrated graphics right now)😬

uh 🙂 I saw that coming, connected to the motherboard 🙂

I’m reading this and I honestly can’t believe my eyes 🙂 he he

🙄 Yeah, I tried plugging everything into the GPU, but the monitor isn't even giving me a signal, so I switched over to the motherboard video out just to try and get the drivers installed.

Everything is hooked up to the graphics card, but the monitor just sits there with a blinking green light—total dead end. Nothing.

Then I plugged it into the motherboard. I tried using both 6-pin connectors on the card, but still nothing. Tried using just one pin, and I actually got a picture, but then when I go to install the drivers, it can't even find the card because I don't have both pins connected.

I am losing my freaking mind here.

A black screen on the monitor often points toward memory issues. You might want to try playing around with the RAM sticks—pull one out at a time and see if things change.

If it won't boot, try hooking it up to a different monitor. I suspect it might be a resolution issue, though I have my doubts; if it were just that, you’d likely see the initial BIOS splash screen before it went dark once macOS tries to load.

It is possible the graphics card has died. Try testing it in another PC. Alternatively, your power supply might not be delivering enough juice. Pay close attention to those variables.

That flickering at the monitor means you’re dealing with a signal drop—it disconnects and then tries to reconnect itself over and over. It’s just constant cycling. Could be the power supply. Or maybe just a loose connection. Give those cables a good once-over and make sure the card is actually seated properly in its slot.

While the monitor is still connected to the motherboard, uninstall the NVIDIA display driver. Just a heads-up though—NVIDIA drivers handle the chipset too, so make sure you're only removing the display driver part. Once that's done, seat the card properly and hopefully, you'll finally see an image on the screen...

Hey everyone. If this were just an issue with the resolution, logic dictates he’d at least see the BIOS POST screen before everything goes black. It would show up briefly, then cut out. I don't know, maybe I'm off base here, but that's how it seems to me.

Turns out it was just a memory issue—swapped it into a different slot and now everything's running smooth.

thanks
