You should be able to reach that no problem; provided the cooling. But it also depends on the CPU performance.

I thoguht that was fixed? I guess not. I have to try the black slots.

I had real problems with 1066MHz RAM and any FSB other than 1066MHz (1:1 was ok, but OC the CPU, and my RAM is only stable @ 1000MHz.) Could be something similar....1333 to 1066 MHz was an awkward divider....maybe 1500 to 800 is the same deal. Can your CPU run @ 1600MHz on a lower divider? Try that too if you can.

Edit:

your Corsairs should be good for 2.25V...but I note that your PSU is 450W. Could be that the PSU is slightly undersized- I had problems with my PSU when I upgraded to the p5NE...465W on my enermax just was not enough.

Edit 2:

Thanks! awesome advice - rep+

I did move the RAM yesterday from yellow to black after reading old posts, but it still blue screened this AM. My ram is the XMS2 C4 so it's "guranteed" to run at 4-4-4-12 @ 2.1 but yeah 1500 to 800 is some weird 15:16 or something divider.

I'll try the 1600mhz at 6 or 7 x tonight - kinda sucks as I have to wait till tomorow AM to see if it works. Could take a week just to make it through a handful of changes.

I thought of PSU too but will try all the settings type fixes before spending the money on new PS. There really isn't "that much" of a load on my system. 1 HD, 2 case fans, no extra power required for graphics card but who knows - maybe just week enough to be unstable when cold.

OK, got an update. I pulled the MB out and stuck it on a cardboard box, wired everything up...still nothing. I have fan power, IDE power, but no visual, and no beep. Thoughts?

You reset the CMOS already I assume? Tried booting with no vid card? Will you still get post beeps if you remove RAM?

I was in the same boat as you the other day - power up and no post, I reseated everything twice, checked the q-connector deal, made sure reset button wasn't stuck. Eventually after giving up it just came back on after sitting 10 minutes or so and hasn't failed again so I assumed something was just loose somewhere and I got it the last time I threw it back together.

- Edit -

Did you try with only one stick RAM, my system behaves VERY erraticly with 2 stick of the XMS2 6400 C4 on default setting. I can't even get into BIOS after a reset without pulling 1 stick - kind of a PITA.

[underdog1425]

Yeah man no beeps, pulled out the vid card, nothing, removed ram, same deal. I put Asus on speaker and sat and watched G4 for 20 minutes while on hold, and went over all of the same things we discussed here with a technician, he says either bad MB or Processor...we know its not a bad processor....so im RMAing the MB.. =/ good thing its not my only system..but i will miss my weekend warrior for the month or so its gonna take.

This motherboard doesn't have a speaker built in (at least mine doesn't). The only way you'll get beeps is if you plug it into a chassis speaker.

E6400 @ 2.933 @ 1.3725v 24/7(i set it, its stable and i havent looked at it again). Peak 3.2 @ 1.4375v I have a thing about running above 1.4v its just personal opinion. I find it hard to believe 1.5v is 'safe' but to each his own...

0608 seems best for me with the E6550 cpu, i have got the fsb to 1980 with 0608, but unstable.With the 0803 I am having problems after 1800.

Can you fill in you system specs on your profile, so i can see what cpu you are using.

[aleiro]

Windows is perfectly safe and the only way to downgrade without having to go out of my way and renaming files and loading into DOS (no to mention i dont have a floppy). I started at 0404 and loaded every bios up to 0803 one weekend and then went back down. Testing overclocks i noticed the voltage requirements were all the same. The only thing i would suggest is make sure it loads your defaults

look into the P5N-D its the newer one with PCIe 2.0

I get the same results and agree completely. I have the 9700NT and I have yet to see temps on Orthos @ 3.2 excede 45c
