7900GT Power Confusion

[Lost.Prophet]

Does anybody know how to install at 7900Gt graphics card? the power ocnnector supplied has two power sockets on the end of the adapter that plugs into the card, but I don't know if both need to be used. I seam to be havign trouble with a few games where it will be fine for a few seconds, then jump, the fine and jump and so on every 5 seconds or so (SiN episodes is almost constant, it is unplayable). ANy suggestions?

Yes these cards require either a connection from your PSU using a proper PCI-E power connector.

Or Using the adaptor that came with your card you must connect two HDD power connectors. One to each of the connectors on the PCI-E power adaptor which is then connected to the graphics card.
You cannot use just one HDD connector in to the power adaptor because if you actually look at the wiring you will see that it is in fact two lots of power, hence the need for two connectors.

Thanks for the advice, I did what you siad but this obviously wasn't the source of the problem. It doesn't happen on all games, at the moment just Sin episode 1 and Tomb Raider: Legend... anyone got anymore ideas?

heat
dust
drivers

btw how much RAM do you have, and what settings are the games on

drivers and dust are not an issue, the parts are brand new (as in arrived on saturday). The heat for all ocmponents are in the green (according to the software supplied with the motherboard) except for the Mb itse;lf but it is only 1 degree into the red. I have 1.5gb of ram, and the settigns are on full, but reducing them to a lower quality doesn't seam to reduce the problem at all.

What Version Nvidia Driver are you using?

I downloaded it on monday it's 9.1.3.1, the on released on 1/6/06

It's not a power issue, I installed a new 500w PSU today, and I have also installed a 120mm case fan so I don't think it is heating either
