Games freeze with 9800GTX sli

[Deren]

Hello,
I am facing a weird issue with 9800GTX sli, I play a game like COD4 in SLI with a high resolution, the game freeze every few seconds. When I adjust resolution or take off the AA, I lasted longer but not more than a minute. If I disable SLI and I turn with one card, no worries. I have this Q8200 Core 2 Quad with asus P7N motherboard and windows vista home. someone can help me on this?

Thanks

You didnt mention information about power supply. may be your power supply is too weak. you must have more then 800W power supply for two 9800GTX. They may be a fault with the hardware of these 9800 gtx cards. Start by checking your drivers, the settings of your SLI configuration, so it looks there's options in the game regarding the use of SLI, check if it does in other games, change driver, reinstall directx9, you have a lot of things to do before adding a power supply, I think.

Hey thank for quick help , I already reinstalled the latest drivers, reinstall directx test with COD5 and Crysis and still have the same problem. At SLI settings, everything seems to me to correct. When I test my configuration at support.asus.com. that I said that I should eat a minimum of 850W recommended. Can you suggest the best 850W power supply ?
