There should be plenty of overclocking guides out there. Just try a google search for something like "evga 790i overclock guide" and you should get quiet a few results.
That was one of the more popular 790i boards and there should be plenty
of threads and experience with it out there.
First: Read Overclocking guides about your specific mainboard, read everything you can read. This will spare you from a lot of trial and error.
Then simply follow these guides, and keep in mind that you use a quadcore, they behave slightly different than dualcores.
Make one step at a time, only increase one value at a time and take time for stresstesting and always take notes / make a table of your settings.
Write down what FSB you set, all the voltages and results, like "POST", "boots to Desktop" and then, depending on the stresstest you use, how far you got.
Another important step: I don't know what BIOS you got on your mainboard, but search the internet for user reports on what bios version for your board appears to be the best for overclocking.
Then don't hesitate to make that version "Xeon ready" and flash it on your board. (Read howto's for that, but it's not that difficult if done right.)
With proper preperation, you are looking forward to a FSB around 450MHz to roughly 530MHz, at least that what the boards should be able to handle. (With a low multiplicator.)
Then it depends on your CPU, PSU and Board how far you can go with 10x multiplier. You should have a blast.
Oh, and depending on your luck, patience and time, the whole process could take a week, patience is the key.
My MSI 790i board kept me busy for around 2-3 weeks. First 790i board with E8200 and Bios v1.23 got me to 440
MHz, then I hit a FSB wall. I tried quiet a lot on that thing and couldn't wrap my mind around it. Then I remembered that I had another board and another CPU that a friend of mine used.
Identical mainboard (MSI 790i), identical CPU (E8200) and the same BIOS version. Fired it up and reached a FSB of 475
MHz before hitting the wall at 480MHz. I didn't try to get it rock stable yet, but it looks promising.
Then I read some post that sometimes, the latest bios doesn't have to be "the best". So I downloaded all aviable BIOSes for my mainboard, flashed and tried them one after another.
There were four of them, three behaved pretty much alike, but one made all the difference. With that BIOS, I managed to boot to the Desktop with 505MHz
Sadly a first test showed that I won't be able to get it stable without dealing with GTLs from the beginning so I reduced it to 500Mhz. First testrun looks promising, tomorrow I will see if I can get that baby trough a custom run.
So in short terms, no board and no CPU are alike, even if they appear to be the same. And checking out different BIOS versions can be rewarding.
