GT6800 PCI-E system restarting, why?

[jmabe]

Hi folks,

I just got a GF6800GT PCI-E from XFX, w/ stock cooling and installed on my new system, comprised of Athlon 3500+, DFI Lanparty UT nF4 Ultra-D, Crucial Ballistix 2x512 @ 400mhz, 2 Sata 120gb HDs and 1 DVD/RW from NEC. The power source is an Enermax EG465VE 430w.

I bought the system mainly for games, and was disappointed to realize that the system goes down during Counter Strike Source (HL2) play, or when I disconnect. Basically, when I get into a 3D game, after I quit the system restarts EVERYTIME. And after restarting, when it goes into Windows desktop, restarts again.

On the Nvidia monitor application, the temperatures are 60-66 C GPU when Idle, 80-90 C when running games, System 48 C and CPU 32 C. The voltages are 0.6 CPU, 1.53 CORE and 1.58 Memory.

I also use 4 heatsinks on my case, and the XFX board doesn't seem hot at all.

So, what could be the problem? Too hot temps? Not enough power?

Please enlighten me, I'm really frustrated.

Thanks

Start by reducing the amount of power your system is drawing. If you have extra cooling fans, unplug them. Any lighting, unplug them. Whatever you can do to reduce power draw without making your system unusable. See if it still restarts on you. If it doesn't, your very nice Enermax might have something wrong with it.

What is the 12V+ AMP rating on your power supply and does it have dual 12V+ leads?

I had basically the same issue, And I think I solved it by using a 2nd power supply to power all my case fans.

keysplayr2003,

I'll try that right now, will post the results later on.

BTW, I applied some thermal paste on my VGA and reseated the heatsink, nothing improved. And I have two of the same card, so I tested both and both report high temps.

About my Enermax, the 12v is rated at 1.5A/33A, and I believe that there's only one +12v lead, but I really am not sure.

My plan is to try this you mentioned, and then buy tomorrow a Zalman or Alligator VGA fan and exchange my Enermax 430w for a 565w unit.

Wow matt, I don't think my case is big enough to handle that, plus I wouldn't know how to go about it.

But I will try to feed more power to the babies.

Thanks
