My First Overclock

[Flanagan]

Hello Everyone, I just performed my first oc and was wondering if you guys can lend a hand. I been at this for two days now off and on, and i just cant seem to get the setting correct two get this chip stable at 4.3Ghz or 4.2.

Here is a screenshot when i had it at 4.1Ghz, but was getting an error from orthos that read "FATAL ERROR: Rounding was 0.5, expected less than 0.4"

The chip is an E8500 and the board is a GIGABYTE GA-EP45-UD3R

Now im try for 4.22 with the following setting and the machine will either bsod, or just reboot. Any help would be great, thank you.

Re: My First Overclock

Thanks, after messing with this for a few days, i finally got a good test with good temps. If anyone else has an E8500 with a Gigabyte P45 UD3R board, and need a reference. This is what i used.

Thanks for the replies, a few of the volts were way to high. I brought them down a bit, and its all good, thank you again.
