What is the difference in the two speeds 3gb vs 1.5 gb?

I would also like to ask if there is any risk in activating my 3 gb/s on my hdd?
The moddel of my mb is an intel DG31PR, the online manual does say it has sata 3 gb/s and it also says it has onboard gpu (which it does not have) so is there any risk in activating the 3 gb when my mb can only handle 1.5?

Thanx!

I enabled it "after" installing xp on the two seagates I have on raid 0 and it caused no problems.
On the seagates you just remove a jumper. I could not tell any huge increase in speed but why not
do it if you can. There should have been a sticker on the drives telling you about the option and
how to disable/enable it.

Thanks just wanted to know if there was any risk couse i downt want to damage anything on my rig, GOD I WOULD DIE IF I DO! Are there aby bios setteings i have 2 change?

You sure it doesnt have integrated graphics?? thats what the blue vga port is for......check it out http://images.tigerdirect.com/itemDetails/...156-out3-hl.jpg

And not you wont break anything, worse case the hard drives will stop working properly until you drop it back to 1.5.

LOL, It does have LOL its just i have never noticed it cause i have never used it thanks now I am off to activate 3 gb/s!

Let us know if you can tell any difference I think it helps burst mode
