the 16X PCI-E lane on my gigabyte DS3P

post #1 of 10
Thread Starter 
am I absolutely tied to the top, blue slot or can I use either and still have it be 16X, I know it only does X8 crossfire. I ask because I would like to move my video card down to the bottom peg so I can put some heat sinks on my tv tuner card and have room for better air flow.

any help would be greatly appreciated.

ok yes that's the specs but doesn't help much. my question is does it matter, as in if I use the other slot will it become the 16X and and the other switched over to the 4x, can I control which is used as the 16x and which is the 4x
post #4 of 10
No, it will still be 4x.

I think he is asking if it is hardwired at x4 or does it switch to x4 when he uses two cards.

logo199 that is exactly it only I will only be using one card. I just want to move it lower on my MB if its not going to affect performance, so I can get a little better air flow.

If you look closely at the second slot - there is only contacts in the slot up to about half way [look at the bottom of the board - easier to see.

I had the same problem with my GA-P35-DS4 [the DS3p with better cooling basically] when i got my 2 HD3870's - the crossfire suffered majorly - with my quad at 3.96 in the 16/4 crossfire i got 17878 in 3dmark06
In my new board [P5E - X38 16/16 crossfire] my 3dmark so far with quad at 3.86 i have got to 20033 in 3dmark06 - broke 20K so i'm very happy with my rig now....
