7970 GHZ: Computer Crash

post #1 of 4
Thread Starter 
Hi,

I have a 7970 GHZ edition from Sapphire. It requires 2 8 pins contrary to its own website, and I am using the 8 pin to molex converter because I don't have 8 pin connector. Full specs of my computer are in my siggy named 'Celapaleis'. I have not overclocked the Sapphire manually yet. My power supply is:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817226002

I essentially have two lines for molex coming straight from the PSU. Each line has multiple molex connecters. I need 4 molex so I used 2 from each line. One line is also used for my fan controller in addition to two molex for the GPU. I only have 2 6 pins and none of them will work for the GPU. I know this isn't ideal but I figured I can squeeze by... because it has 635w power.

When I run windows experience index, it crashes when testing buffering for gpu and when I play video games it crashes as soon as any real rendering is going on. The psu is 635w but is 5 years old. My suspicion is the psu being n00by. I have tried the latest and the beta drivers, both of which crash at the same time. I have installed dx9 for running dx9 games and I tested it running dx9 games.

Before this I used my old SLI 8800gt in the same build. Ran windows experience test without a hitch, but I didn't try to play it with any real games.


Any ideas? mad.gif

EDIT:
Just tried Oblivion. The menu animation lags and turning up to full resolution crashes the computer. But I run Aero without any difficulties.

I think it's a power problem...

I've never heard of that PSU before. Do you have any PSU's to test to see if the issue continues? Head over to the PSU section and see the list of good units to purchase.

New power supply son. Same thing happened to me. 99% that it is a power supply issue. Never heard of that brand, so it might be faulty. OR...... you are pulling to much from a single rail. Check your rails. Make one PCI come from one rail and the molex from another. Good luck thumb.gif

Double checked your post. Yea I think you are pulling too much from a single rail. You might be able to get some adapters to turn both those 6 pins into a single 8 pin and then make another 8 pin from the Molex. Pretty sure those are running on seperate rails so you would be good to go....


But, there are chances that that might not work, your power supply might be degraded or just faulty, especially since it is from a not so well known brand. I would suggest getting a new one. Better for future builds and will have less chances of killing your hardware. Seasonic and Corsair are the way to go. But others are good. Check their OEM and the reviews on the units. Good luck again biggrin.gif
