what PCI lane to put GPU in

[Silver]

i was wandering if it makes a difference if the card is located in any other lane then the first one.

i have a maxsimus iv extreme and in the manual it says batter to place it in the first one for batter performance, but i rather have it in the third one for batter air flow.

Depends on the motherboard and what the PCI lanes run at. On the Maximus the first lane is x16 and the secon x8 so if you had it in the x16 it would run full speed but if it was in the x8 it would run at half speed.

I think that's how it works anyway i'm not to clued up on it myself.

the highest PCI-E lane is normally the one closest to the CPU slot

to verify this, tilt the mobo away from you (with the CPU socket furthest away) and look for the copper pins. the fastest PCI-E lane will have the most pins

well i've tried putting it in the last slot, but then i noticed it runes via the NF200 chip, and as i understand in adds latency so i put it in the second slot, since i have the HAF X i wanted to use the air tunnel for the GPU card, and the second slot is the highest one the will allow me to install the air tunnel.

but then every time i start a game, as soon as i start playing the image freezes (but the sound goes on) for about 2-3 min and then i get a message in windows that says the GPU has recoverd from a fatal error or something like that.

any one got some ideas to what all that about?

ok so turns out the even in the second slot it runs via the NF200 chip, so now it's back in the first one and i still keep getting that same error massage.

ok problem solved, i don't know if it's asus, nvidia, or microsoft fault but it turns out that every time i change the gpu to a different slot i need to remove and reinstall the gpu drivers in order for it to work as it should, hope this will help someone in the future with the same issue
