I only see one cable (with two ends) coming to the vid card.

You need two SEPARATE cables coming from the power supply to the vid card.


I asked you earlier if you were using a Y cable.

You think using two separate cables will fix the issue?

Still doesn't explain why randomly it stops working after 7 hours

Yeah, I think that will fix the problem. That 5700 XT draws a LOT of wattage, almost 300W after 7 hours or so the power supply is probably starting to suffer a bit.

Here's a similar question another person had...


https://forums.d2jsp.org/topic.php?t=82095643&f=199




The specs for your power supply, on Newegg syas your power supply has 4x PCI-E connectors (probably 2x Y cables) You should only use ONE connector on EACH cable. So your vid card would need 2 of the cables...all the way from the PSU to the vid card.
Just let the other halves of the Y cables hang. You can ty-wrap (zip tie) them out of the way if you want.

The point is...we don't KNOW for SURE if the card can run on a Y cable. We DO know for sure it can run on TWO cables. So, if you still have the problem.... then we KNOW it's the motherboard or the CPU (doubtful).


Both the 5700 XT and the 970 are high wattage cards.




/ee Those Y cables are for lower wattage cards like the 1060 or the 1660 for example. And even then, it's not really a good idea.


The 1060 only uses about 50% of the power that the 5700 XT does
The 1660 only uses about 60% of the power that the 5700 XT does.

I'm about to try it because that's how desperate I am...; but I'm still curious why I would bother trying this, when I plugged in my RTX 970 it didn't work...

The GTX 970 uses about 10% MORE power than the 5700 XT does.


The old gtx 580 uses about 20% more than the 5700 XT, and the even older GTX 280 was a power PIG! LOL




As time passes GPU makers aim for two things... smaller dies and lower power draw. That's why the price keeps going up.


Heat is the enemy of digital components. The more heat the crappier they work. Especially power supplies. That's why when folks seriously overclock things,,, they need liquid nitrogen to keep everything cool. Air or water just can't handle it when you really crank things up.




When your PSU is nice and cold it only puts out 744W at best. The warmer it gets, the lower the wattage output gets. When you try to run a powerful vid card on only one cable... it gets really warm.
Keep in mind, that your power supply is running every thing in your comp (except the monitor). It's already straining some.


/e Even with two separate cables you may still have the problem. But we have to make SURE that the single cable isn't the issue before we troubleshoot further. I've seen MANY times where the single cable WAS the issue.

Using two separate Y cables did not solve the issue.

Nor did using a Display port cable to the monitor

Ok, now you know it's the motherboard or the CPU.


I would check the CPU for leaked thermal compound, or bent pins.


Btw, here is your power supply stats...w/e one you have...







/e When you do find out which one it is... still use TWO cables for the vid card.


Also... I know we talked about it... but you need to make SURE you tested each of the sticks of RAM one at a time in all four slots. Like stick A in slots 1 then 2, then 3, then 4. Then do the same with stick B.

The RAM is probably OK, but until we KNOW for SURE that both sticks and both slots you use are OK, we can't troubleshoot further.

I took a look when I rebuilt the new motherboard and there was no leakage nor bent pins.

Could there be a more internal issue with the CPU that I cannot see?


Whats more likely to occur?
Two bad motherboards? or one bad CPU

Probably two bad motherboards. Or maybe one bad motherboard, and on the 2nd board the thermal compound leaked. Or a pin got bent.
Like I said before... I've never seen a CPU go bad, by itself unless severely high voltage. I've have seen some where all the cores didn't run at the same temp...and those got RMA'd for overclocking purposes. You need very similar cores when overclocking.

Anything can mess up a motherboard bro. Just flexing it a bit too much can crack those tiny little solder runs. Motherboard have a zillion components on them. But as I said... Best Buy can check that for you...maybe charge you like $50 or some shyt.


/ee Make sure you check the RAM like I said in post #27.


Also I would call ASUS like I said before. It could be something stupid like you need a BIOS update for that vid card?

If you call ASUS... have food and drink nearby, make sure you've done your bathroom business, and it's best to call them early in THEIR working day.

Yeah, I'll definitely be making a phone call on Monday to ASUS.
I made an account on their forum today, but need admit approval before posting anything.

Other than checking the RAM; the only other thing I can really do is wait for my replacement CPU on Tuesday right?
