PCIE 3 enable or disable?

[cooperb21]

I noticed in my bios I can enable or disable PCIE 3. I'm wondering should I enable it? I had my pc for a year and never noticed. Is there a difference and do I need to uninstall gnu drivers or will it automatically take affect.

There's not really any difference.  Just leave it at default.

If you have a dedicated GPU yes enable PCI 3.0..

It was this.

says pcie gen3

then select it and it says pci express gen 3 support enable or disable are choices

Enabling it will never hinder performence. At the worst case scenario, your performence wont increase nor decrease. At the best, it may increase

Turn it on

For single GPU having PCIE 3.0 or 2.0 have no performance difference whatsoever. But if you planing to do dual cards then you would need it, so it would have the bandwidth.

Yes you will PCIE 3.0 Is the upgraded ver of PCIE 2.0 If you have it it is suppose to be ON As this feature is useful under some SLI Config's

Its just the bigger better ver If you have the option to turn it on then do so you should see some inprovement on SLI

I can't say it would be a huge difference, but I've seen maybe a 5% improvement? Better then nothing.

Well its not something that is going to hurt if you have it why would you not have it on PCIE Gen 3 Is an upgrade he wasnt useing its like buying a soundcard sure it might only be 5% better then on board but you still payed money for it He payed extra for a feature he isnt useing

That would be 3 FPS out of 60

[Trik'Stari]

Enable it :because reasons.

 

No reason not to, at least that I can think of.
