2900XT overclocking

[Hatman]

I read in a reveiw, that to enable ATI Overdrive and/or overclock correctly, you need a 8pin connector and a 6pin connecter, rather than 2x 6pin connectors.

I looked at that because it had enough power to power 2 of the cards and could power 2x pci-e slots, as in crossfire.


However, does it have 2x 6pins and 2x 8pins? Because I would want to overclock both thr cards at somepoint in the future when they NEED the extra power, not anytime soon, but still.


And if it doesnt, whats a good PSU for it?

Thanks.

That PSU you link to only has 2 6pin connectors.

There's a single 4/8 pin CPU connector, but that won't do it.

You'll only be able to power 1 card from that PSU you posted. Not sure what you can get in the UK, but Fortron (FSP), Antex and Gigabyte all have PSUs with 2-6pin AND 2 8-pin connectors.

BTW, you can overclock with just the 6pin connectors in place you just need to use the third party OC software because Overdrive won't let you without the extra 2 pin filled.

Thanks for advice. Personally Id rather use ATI overdrive rather than a 3rd party software.

This seems to be the only realy one there is available t an "acceptable" price tag.

So I think I'll have to go with this one.

Thanks mate.

actually, most people prefer ATI Tool over CCC/overdrive for overclocking because of the more diverse options and the smaller footprint, you should try it.

Ummm... is there a digital signature? Vista gags on this sticking point. For XP no prob.
