Re: First OC - Newbie needs help with EP45-DS5

You may or may not be able to with the stock voltage? All Chips are different so it is up to your chip really. And do keep in mind your board has a large vdrop/vdroop. So what you set in the BIOS may be .6 or so less in windows.

Try this >>>

Re: First OC - Newbie needs help with EP45-DS5

Thanks Lsdmeasap! Worked a charm. I've tweaked the settings you gave me and now I am idling in the mid 30s and peaking in the low 50s after several hours of Prime95 torture.

Only using two silent fans in my case as well :-)

Thanks again!
