ill try tht no i took them off auto (suto had vcore and fsb set on 1.3) i set them on manual defaults
ya i know i was suprised at only one person responding to this thread
ill let u know how it goes

Have you upgraded your Bios to P08? If not I attached it below. With the 790i Ultras, they had some serious issues until they released the bios updates.

I'm going to grab my voltages from my bios that are rock solid on a 1680fsb.

unless jumping da cmos resets da bios to original yes im running p08

Yes! ChickenInferno is here!

Jumping the CMOS shouldn't change your bios version. You might consider flashing it again; I've seen really bad instabilities with a bad bios flash.

First of all check all of this to make sure that is how I have them.

PCIe x16_1 & x16_2, MHz: 100
PCIe x16_3, MHz: 100
SPP <-> MCP Ref Clock, MHz: 200

All Spread Spectrums: Disabled (There are five or six)

Unlink your ram and lower it 1333mhz 9-9-9-24-2T with stock voltage (Keep It There)

P1 and P2 should both be changed from Auto to Enabled (You may not have this)

Limit CPUID Max Val: Disabled
Intel Speedstep: Disabled
Thermal Control: Disabled
C1E: Disabled
Execute Disable Bit: Doesn't matter I leave enabled
Virtualization: Doesn't matter I leave enabled

Voltages:
Vcore: Put it on stock for the moment
CPU FSB: 1.400 (I actually use 1.5 because I have a 65nm quad. Your 45nm quad would be fried at this voltage)
Memory: Stock
SPP: 1.42 (or 1.47)
MCP: 1.500
CPU PLL: 1.500

I would reccomend keeping your ram at 1333 and just leaving it there until your CPU overclocking is done.

The method to my madness for overclocking is to raise up my FSB by 10 so starting with (333x7 for my CPU) I then have 343x7, which is raising your overall CPU speed by 70mhz and running LinX for 10 runs. If it passes then I raise up my FSB another 10 for 353x8 and run LinX. If that doesn't pass, then I increase the vcore by one bump (.00625v on my mobo) and try running LinX again. If it passes then I increase the FSB by another 10. If it fails again I increase the vcore by another bump and try LinX again. When you start getting to your max overclock you may bump the vcore 5-8 times just to get stability.

Believe it or not, doing this will give you the absolute max overclock in a day or two. Once I have the maximum overclock (limited by either temperatures of voltage), then I run prime95 Small FTTs for 12hrs. If it passes great, if not bump by one more vcore and try Prime95 again. ---This is ussually where people are satisfied that their overclock is stable and it really is a good sign that it is.

Since I'm a little paranoid, I then run 12hrs of Prime95 on Blend and OCCT with Small Data Set for 2hrs.---At this point even I call it stable.

wats cpu pll i only have 5 voltages not 6
ya ill try this nd raise fsb to 1600

CPU PLL may only be available in the FTW and not the Ultras.

I wouldn't just try to immediately raise it up to 1600mhz. You will make yourself go crazy trying to find what voltage to make it stable. If you start at stock and just slowly move it up, test stability, increase voltage if you need to/retest stability, and repeat; then you will find your max overclock in about a day or two. If you just jump up to 1600mhz you may find spend days trying to find a voltage to make it work. By doing it step-by-step, you will always know your last maximum overclock and voltage in case you just can't get it to go higher.
