Ok, so I've got a cheap/old motherboard* which only has 1x PCI-E 1.0 or 1.1 port, probably 1.0.
I've got a Radeon HD 6850 which is a PCI-E 2.1 card, but is backwards-compatible with PCI 1.0 or 1.1 ports (not sure if with both or just v1.1, but either way the card is working on my computer).
However, I noticed that I have a setting in my Bios to change the (only 1x) PCI-E port from the default and minimum 100MHZ to a maximum of 200MHZ [and every 1 point in between], which is, as far as what I read, the regular speed of a PCI-E 2.1 port.
And I was wondering if I should try testing this option (OCing PCI-E to 200MHZ) out to test for increased performance - that is performance closer to what it's designed for on a PCI-E 2.1 port.
However is this at all risky for some reason? I mean can the PCI-E 1.0/1.1 port handle it? And it's only set to 100 MHZ by default because PCI-E 1.0/1.1 gear aren't generally designed for any higher speeds? (or is there something else to it which I should be aware)
*For the record the MB is a G31TM-P21.
Also, I wasn't sure what category to put this in; MB-OC or GPU-OC, but yeah.
