I'll just give you a warning beforehand, because I had the same problem with my P5B-E and DDR2-800 memory.
If you get a certain revision of the board, the memory will try to boot at 1.8V standard, which would probably mean that your OCZ memory wouldn't boot with that board unless you were to take 1.8V rated memory and changed the voltage to 2.0 in the BIOS. I had to let the store I bought it from flash my BIOS before sending it to me. If you are going to order both of those parts at newegg (or your entire system in fact) see if they can check for you if the parts boot well together. Consider the quote below;
I just set the same board up yesterday and had the same problem. Initially it booted fine with the original bios so I updated the board to the latest bios and then nada, dead as a door nail same as yours. I found out it's a ram issue (I'm using OCZ Platinum) and an unbelievably stupid bios setting on the part of Asus I might add. Here is what got me back in the game:
1. Make sure you have a speaker connected to the MB so you can hear the beeps.
2. Remove all the ram and start up the system. If you hear error beeps then good, the motherboard is probably working fine. If no beeps then you have other problems that I can't help you with.
3. Try a single stick of your ram in the slot furthest from the cpu and see if that works.
4. If it does work then go into the bios settings and take the mem voltage from "auto" to 2.0 volts. Then your ram should all work again normally.
5. If it doesn't fire up with your single stick of ram then you have the same issue as my OCZ and you will need to get a single slow stick of ram that only requires 1.8 volts to start. I had to go and purchase a cheap 256 meg stick of DDR2-533 ram and used that by itself to start up the system. VOILA! Once it booted it made the change from Auto to 2.0 volts on the bios setting for ram voltage and then rebooted the computer again with my OCZ ram instead of the the DDR2-533 and everything worked fine from that point.
Hopefully that works for you and with any luck Asus will fix this in their next bios. Love the board so far and have an e6400 running at 3.0ghz so far with stock settings and solid as a rock. Pretty sure I have lots more room to go on the overclock but I'll let it burn in first. Pretty darn pleased so far other than the above bios quirk. Good Luck!
You have also picked OCZ and from what I've read, OCZ doesn't work too great with the P5B-E. In fact, it's a very picky board when it comes to memory. So do a search to see if the motherboard has been tested with your memory, or get other memory. My G.Skill worked fine.
While your board is being flashed, you also eliminate the possibility that it doesn't support C2D processors (a problem that my friend had with his P5B Deluxe).
Anyway, it's just a warning. Other than the little BIOS flaw, the board is great (although my pc is currently at repair, the motherboard might have given up already, but my case is exceptional).
