Hi,
How slow is slow?
Gigabyte boards are really not the quickest out of the blocks and there are several threads throughout the forum that talk about slow POST and BOOT times.
If you are using a Floppy drive or have Floppy Drive enabled within BIOS then, for some reason, the POST process seems to take even longer so it is a good idea to disable this. Also disabling the Full Screen LOGO in BIOS is a good idea as it is unnecessary and just holds everything up.
Another thing to try, is changing the SATA port that your OCZ drive is attached to. (Sounds silly but it can make a real difference)
