Re: Questions regarding Q9550, EP45-UD3P Overclocking
Hope I can help!!
These you ask about (3.3V, 5V, 12V and VBAT) are your voltages from your Power Supply, nothing to do with your BIOS settings. That should help you sort some of your voltage thoughts out.
The only voltages you will be able to check from the BIOS to Windows is the Dram Voltage and your Vcore. You can observe both of those with Everest Ultimate, which you can get here (I think you may be using this anyway by the way you worded those voltages above?) >>
Voltages and Temps will appear in the Computer/Sensor Section
Good thing you have asked for help as you cannot leave voltages on Auto, at least a few of them will be WAY Overvolted when you overclock (Vtt-Termination and PLL)
Your temps are/will be ok once you set your own voltages, you should be able to hit 4Ghz or more without many issues and still be around 70-75C I would think.
You do have a lot of Auto's so if you want help with this profile let me know and I will advise.
To save these settings you are using now you can hit F11 on the MAIN page of the BIOS and name this 3.8 or something, then start on your 4Ghz setting and save that as a new Profile, be sure you move the cursor down so you do not overwrite your first profile. F12 on the MAIN page of the BIOS is load. If you switch between profiles, always check Memory Multi as sometimes it gets set back to Auto which can be to high and cause a boot failure leaving you with no clue as to why until you notice it.
Here is what I would suggest you change/set for 4Ghz, voltage ranges and timings would actually be advised for 3.8-4Ghz so you can use them on the above as well.
