Here's the step by step:
THIS IS USING THE F2 BIOS; I HAD A LOT OF TROUBLE OVERCLOCKING THE F4 OR F8 BIOS.
BIOS screen after pressing (mashing) Delete key on startup:
1. Click on M.I.T.:
2. Click on Advanced Frequency Settings:
3. Advanced Frequency Settings:
Leave the CPU Clock Ration at 33x as we're overclocking the Turbo (on the F4 or F8 bios I found changing this DID change the turbo but with the F2 you just leave it)
Some Enable the BCLK/DMI/PEG Clock Control so they can change the BCLK between 99mhz-110mhz. At this point with this board I haven't found that this helps and stability is more easily ancheived leaving it at disabled.
I changed by X.M.P. to the Profile1 putting it to 1600mhz @ 1.65v @ 9-9-9-27; this way I don't have to manually change the timings or voltage or multiplier (it automatically changes it). Some people report greater overclock stability with manually inserting all the timings, voltages and ram multiplier according to your rams specific stats.
CLICK ON ADVANCED CPU CORE FEATURES
4. Advanced CPU Core Features
I leave the CPU clock ratio but if you changed it in the Advanced Frequency Settings it would also change here. You can see what settings I use:
I change the Turbo's to 45 (new multiplier to give me 4500mhz!)
I change the Turbo Power Limit (I've referred to this as TDP but I guess it is really the Turbo TDP (thermal design power); someone correct me if I'm wrong) to 300 watts as the Processor will use more than the 95 watts. We're basically removing that limit so that it can be overclocked. I do the same with the Core Current Limit (amps) which IS called often by the term TDC (thermal design current).
I leave C1E on; some people don't. At first I left EIST off but I felt my voltage consistency was better between full load and stressed full load with it on.
C3/C6 I turn off.
48x (oops I do have the EIST off here but am currently using it with it on)
ESCAPE BACK TO THE M.I.T. SCREEN AND CLICK ON ADVANCED MEMORY SETTINGS.
5. Advance Memory Settings
Again my XMP Profile1 is loaded. You can also manually input all the volts, timing and multiplier. At 4.5ghz I leave the performance at Turbo but with my 4.8ghz overclock I change it to Standard (this can give a more stable overclock). I am not overclocking my ram. If you're having trouble getting a stable overclock you can try leaving these at the default settings without the xmp profile.
ESCAPE BACK TO THE M.I.T. SCREEN AND CLICK ON ADVANCED VOLTAGE SETTINGS.
6. Advanced Voltage Settings
I've heard that fiddling with the other voltages can help get stable but I haven't seen any measurable difference yet; I now leave everything on auto but the DVID. By the way... I did have an overclock of only 43x with the dvid at -.08. For 45x I need +.03 and with 48x I need +.10-+.11. That's a significant difference of voltage between 43x and 45x.
Here are my voltage settings for:
ESCAPE BACK TO THE OPENING BIOS SCREEN AND CLICK ON INTEGRATED PERIPHERALS
7. Integrated Peripherals
I have my SATA Control Mode to AHCI as IDE sucks and I'm not running a RAID. I disable USB Legacy and there is no need for it. (You DON'T want to change this unless you're just about to install your OS. If you have Win7 there is a hack to change it retroactively. BUT JUST DON'T CHANGE THIS; best practice is to reinstall your OS if you need this changed.
ESCAPE BACK TO THE OPENING BIOS SCREEN AND CLICK ON POWER MANAGEMENT SETUP
8. Power Management Setup
I put HPET Mode to 64-bit mode as I'm running a 64-bit OS; I don't know if that is correct thinking but after fiddling endlessly with trying to OC one gets a little superstitious.
By the way: a 212+ cooler brought temps down 8-10 degrees. Getting a good cooling case (Sniper BLK ED) brought it down another 6-8 degrees (10 degrees on the GPU).
Let me know of any questions or corrections.
Hope this helps guys,
