8 pin PCI-e adapter

post #1 of 8
Thread Starter 
I found a few 6 pin to 8 pin PCI-e adapters for the HD2900XT. My question is will this even give the power needed to overclock it if your PSU has the power?

Okay, I have absolutely NO experience with the 2600's, but it seems to me that as long as there's enough juice in the PCI-E power rail, then it doesn't matter how it connects to the card--whether it's 6 or 8 pin. But maybe I'm too noobish in the 2600 area... I do not know, however, if overclocking is enabled/disabled if the card does not have the 8-pin connection--perhaps that is the case?

How does the adapter connect? from 6 to 8? Then no it's not working right. 8 has more juice flowing..

yes, if your 12v rail has the amperage. you can overclock without the 8pin with 3rd party software, but if you want to with the ati stuff you will need the 8pin.

Actually the extra two pins are ground and only serve as wire protection from the extreme amperage during overclocking.

I believe the 8-pin adds an additional line and ground to the 6-pin plug. This allows the wiring to "safely" carry more current. Just adding more grounds would not accomplish anything since you would be increasing the current of the original two lines. 18ga wiring of 6-pin should be enough to carry the load for 8-pin... IMO
Once again...
