Just to back up on your troubleshoot, if you have not yet try these:
1) Make sure that your RAM and CPU are unlinked for the FSB. Set your RAM to stock spec and/or UNDERclock it with lower voltage. The key is getting your RAM stable at the lowest voltage possible on this board. Run MEMTEST86 overnight to check stability.
2) Set your NB voltage to 1.56V (24/7 safe) or 1.7V (testing only- not 24/7 safe). This board likes to steal power from the NB and give it to the Vdimm and Vcore when they are cranked up (hence getting the lowest Vdimm in step 1, and lowest Vcore in step 3) Also keep an eye on the NB temps- 55-60C is the max safe range, IMO over 50C is high. Hot NB=unstable system.
3) Try starting your Vcore low (maybe 1.25ish) and turn it up ~0.05V each boot until you can get into Windoze and benchmark. Increase Vcore slowly once you can boot until benchmarks are stable. IMO 1.45V (with or without +100mV) should be plenty of juice to run at the 1333FSB on a quad (B3s included). Sometimes too much voltage is as bad as not enough.

Seemed to work! I got it OC'ing as normal now. It seems the BIOS is off quite a bit from what I manually set the voltage to but the NB and VCore is set and working. One question I have though considering the temps. I run up the speed to about 25% higher unlinked and I noticed big differences in temps between 4 programs. Here is the data:

Running Orthos-
SensorView: 53 (Only a single temp)
TAT: 58-51 (shows two temps)
CoreTemp: 42-49-46-48 (All four cores show)
NVidia Monitor: 57 (Only a single temp)

Now, which should I trust because CoreTemp shows all cores but is way lower by almost 10 degrees almost 15 at some points. Also, this is funky, what Idle Coretemp is higher than under full load. Is this due to fan speed not kicking in?

Thanks for the help guys I really appreciate it.

Are those load temps? CoreTemp 0.95.4 was supposed to fix the detection of TJunction, but my friends e2180 (and it looks like yours) are 15 deg too low. I used speedfan and manually set the 15C offset in the config.

Yea those are all load temps. The other sensor programs show normal when I unload the CPU they go down. CoreTemp likes to go up??

Speedfan was not working very well on my PC. It wouldn't show any temps at all. What would you suggest on keeping as a temp identifier.

use CPUCool

best program i have found.

Is that all they really changed?

I hope not i am going to try it later tonight.

I may at last flash my BIOS. Im still on 0307.

Just checked the Asus website and it doesnt have it on there atm.

I will give that a try. Hopefully it will give me an accurate reading or at least show me which ones I am using isn't correct. Thanks man.

I'd go with Coretemp- it reads straight off the CPU die. If it displays a Tjunction of 100C you have the right version, if it says Tjunction is 85C then add 15C to your temps and get the latest version of coretemp.

Don't use TAT, it was specifically written for Pentium M chips and not accurate for C2D, C2Q, or any other Pentium (1, 2, 3, 4, D, dual core E2xxx series).

I'm not sure about Sensorview, never used it. The Nvidia and Asus tools measure a sensor placed in the center of the 775 socket under the chip- usually they read lower than other programs, but may read high if the back side of your MB is insulated or mounted very close to the case (there should be about 1/4" standoff from the case to the MB).
