Ok guys heres the lowdown:

Specs:
Asus P4C800-E Deluxe
P4 3.0C
Mushkin DDRAM 2 x 512 PC-3200 (2.5-4-4 / 2.6V)
ATI 9800 Pro 128MB
Windows XP Home Edition
Antec True430 powersupply

Cooling:
4 case fans
Zalman Heatpipe and fan for VGA card
Zalman copper heatsink w/fan for P4

From what I know which is very little, this MB has the ability to be OC's quite easily yet I have had no luck. In the bios I set the OC for a mere 5% over norm which makes my 3.0 run at 3.15, at the damn thing won't boot.

I am open for suggestions. :?

im a bit of a newb myself but ill try to help you. make sure that ur hsf is properly seated onto ur processor and that u properly applied some thermal compound. is ur memory and northbridge receiving good air flow or cooling? If ur still having problems, try checking these links http://www.tweakfactor.com/articles/tweaks/neoocguide/1.html

Yep heatsinks and fans all seated well and working propely. Ambient case temp is usually around 82° F and CPU runs around 84° F resting and under gaming conditions around 105° F maximum. I have a huge 120mm blowhole in the side of my case as well as several other strategic fans to move air across memory and cpu.

Make sure your pci and agp bus are fixed to their frequencies. Could try giving the ram a little more power, if that doesn't help change the ratio between fsb and your ram.

I'm almost positive it's the RAM. I have 2x 512MB PC3200 Mushkin 'Blue' Level II and it refuses to overclock. Even changing the timing a little tighter and it locks. :(
Nice system. :)

My system is similar to yours except the ram.

First try loosening the timings, then oc a bit at a time - by 5mhz, test (run memtest86 v 1.20) until you max the oc. Once it is maxed out then tightening your timings.

I'm not sure of the timings or settings for your ram. Some ram need more volts to run at higher FSB speeds some don't.

PCI/AGP should be locked to 33/66 - no higher I'm told. What other bios settings are you using?

Ok Mushkin has a support release for the Intel 875 canterwood for mem latency. I have the basic "green" version. Here is what they recc.

CAL Latency 3
Ras to CAS 4
Precharge delay 4
Ras Pulse 7
Burst length 4
Voltage 2.6-2.7

I have tried this with no luck and when I followed their instructions further, my system wouldn't even turn on. I had to clear the CMOS to get the damn thing working again.

What was the FSB set at when you tried to post? Try setting it to 201 with the timings they recommend. Apparently Asus boards are fairly agresive when the FSB is set at 200.

I think I read somewhere that the burst length of 4 does nothing so you might try backing it to 8 and see if it works.
