I've googled and browsed across forums quite a bit and I'm fairly comfortable with setting the bus frequency and multiplier for my 955 BE as well as playing with the voltages, but I had some other questions that I didn't really find exact answers to so I was hoping for some assistance.
I wanted to start with a mild overclock to say 3.5Ghz for my 955 processor.
Motherboard: Asus M4A79XTD EVO
Processor: Phenom II X4 955 BE
Memory: G.Skill Ripjaws 4GB (2x2) DDR3 1600 8-8-8-24
CPU Cooler: Corsair H50
So in the bios, I changed the following:
CPU Bus Frequency: 250
CPU Ratio: x14.0
CPU Voltage: 1.3500 (Which I believe was the stock voltage)
RAM Frequency:Well, I had to set it at 1333 because the only two other options were like 1666 or 2000 and I felt those were way too high for my RAM.
Now, pretty much everything else I left set to 'Auto' because I wasn't sure if I should change it, and what I should change it to. I also wasn't sure if leaving it to 'Auto' was bad because it might scale something way up over what it should be, like the Northbridge Voltage. (Everest seems to show the NB voltage being the same as before the OC at 1.3750 but I'm not sure if that's even an accurate number?
I guess my main questions are, what other settings do I need to change, and is it okay to leave stuff on 'Auto' if I want to keep them at default? Also, can I try to tighten my RAM timings since I'm using the lower RAM frequency? Or should I try to use the slightly higher than 1600 frequency?
My temps for the 3.5 OC seem to be 47c - 48c under Prime95 load after about 15 minutes. Was idling around 34c - 35c
Here's some screenies of my bios settings for the OC.
