First of all this can be used for other 650i's I'm sure, The specifics however are for the EVGA. Sorry this is a bit tardy lets just say I've been busy. This is basically a draft so far.
Secondly I'd personally like to thank Astral Abyss, I haven't used Intel since the PIII So some of this was kinda confusing to me. The thing about the 650i/ 680s and the c2d is OCing is easy as hell now, it's easy to over think it. I remember my Barton 2500+ and writing out a page of math to figure out my speeds ect.
Thirdly this is what I did it works for me use at your own descression I am not liable if you do something wrong. This using the P02 BIOS. http://bxclub.dk/Evga650i-ORG.BIN Which can be found here they seem okay, the P03 are out now but they dont seem to have F*ck all for us except quadcore updates. EVGA really likes to shrug us off it seems kinda like how we'd have to spend $150+ to get a board that has memory options that go higher than 2.1v
I also reccomend buying a fan for your northbridge and a heatsink for your Southbridge or they will get retardedly hot. I went with a copper heatsink on my SB and a 40mm or so fan for my NB.
Okay now! BIOS:
Under: Advanced Chipset Features
System Clocks
HT Spread Spectrum - Disabled
PCIe Spread Spectrum (spp) - Disabled
------
FSB & Memory Config
What I have them set at:
Unlinked
My fsb (QDR) 1333
Mem (DDR MHz 800)
-------
Mem timings under PARAMETERS Set them to expert then change them to the settings you want them to be, whatever your ram would run ideal at. Don't touch the bottom ones leave them at auto. I should note even if the settings you change already read as say 5-5-5-15 go in and do it manually just so it is set properly by you.
My ram is set to 5-5-5-15 2T under this tab
-------
CPU Config Options:
Limit CPUID MaxVal - Disabled
Intel Speed Step - Disabled
CPU Thermal Control - Disabled
C1E enhanced halt state - Disabled
Execute disable Bit - Enabled
Make sure all your cores are enabled 0 and 1 if you have two cores for example. You most likely wont have to touch it they will probally show just fine.
---------
System Voltages should be set to whatever you see fit, you'll know more when OCing.
For example Mine:
CPU core: 1.35625
CPU FSB: 1.2V
Memory: 2.1V
nforce Spp 1.2V
I should note some guides online people have their SPP and FSB at 1.4v, clearly it's not needed unless you have stabuility issues but I think it's just going to heat up your mobo more than it needs to more than anything.
---------
Under Advanced Chipset Features still:
Overclocking Recovery - Enabled
System Bios Cacheable - Disabled
Video Ram Cacheable - Disabled
HPET Function - Disabled
NVIDIA GPU ex - Disabled
----------
Power Management
ACPI Function - Enabled
ACPI Suspend Type [S1 (Pos) ] <-- I reccomend this especially if you have Vista**
Power on by Alarm - Disabled
Pwr On after fail [Off]
Power on Func [Button Only]
--------
PnP/PCI Config tab leave as is, you won't need to change anything in there.
---------
Power Management Fan settings stuff:
If Temp > 70C set fan at 100%
If temp < 50C set fan at 100%
Manual fan speed %100
Chasis span speed %100
(I should note the fan settings for this board suck, there are bunch of complaints)
Now we completed Part 1 of the BIOS setup. I don't reccomend changing your stock CPU speed or changing your default voltages yet. Just go threw and change everything that needs to be enabled or disabled and save then exit.
****I will continue with the actual OC part later. It gets fun from there but this crap needs to be done and I need a break****
