As 'Fishface' posted, you need to post the exact model of your motherboard.
That should be silk-screened on the motherboard or at least should be in the
ordering information.
The most likely reason your system is not posting is that you have the
memory speed set MUCH to high.
What you need to do to get a reasonable overclock is to
RAISE the CPU clock (your motherboard will either offer a setting of 800 MHz
for the FSB speed or 200 MHz for the CPU clock. The FSB is quad-pumped, so
4 X 200 MHz = 800 MHz for your E4400.
AND
You must set the Memory clock so that the memory is NOT overclocked.
Depending on your motherboard (I don't really want to read yet another
motherboard manual), this may require
EITHER
specifically setting the memory clock to ASYNC ( the memory clock is not
synchronized to the FSB) and to DDR2-533
OR
setting a CPU clock : Memory clock ratio that allows the memory to operate
at DDR2-533 specifications or slower.
THEN, after picking the correct alternative for your motherboard,
Set the CPU clock to 225 MHz or the FSB to 900 MHz, whichever is appropriate
for your motherboard.
Once you get a mild overclock like 225 MHz X 10 = 2.25 GHz, then you can try
to raise the FSB speed (CPU clock) by small increments, testing for
stability after EACH change.
As some point you may need to raise the CPU core voltage. But perhaps not.
I have an overclocked system I am using to post this message:
EVGA 680i motherboard
E4300 CPU
2 X 1 GByte Patriot DDR2-1066 memory;
The FSB speed is set to 1200 MHz, the Memory clock is set to 1200 MHz. For
this particular motherboard, that means the CPU clock : DDR2 Memory clock
ratio is set to 1:2. This gives a CPU speed of 2.7 GHz. I picked this
overclock because the system is stable with the CPU core voltage set BELOW
specification, and getting a few more hundred MHz isn't worth the added
strain. You have a different motherboard, so additional BIOS settings I use
likely will be of little use to you (for one thing, the EVGA 680i
motherboard has ~ 50 different overclocking parameters that can be set in
the BIOS.)
Not to put too fine a point on it, but you are just going to have to get in
there and dig. And perhaps spend days trying different settings in the BIOS
and different jumper settings (if appropriate for your motherboard.) That's
how you learn. That's how all of us learned to overclock. It may take you
a month or more to get a satisfactory overclock. Think of it as part of the
fun of overclocking (it actually is.) As long as you don't increase the CPU
core voltage more than 15%,nothing you can do will destroy your CPU or
system as you attempt to overclock.
By the way, try to use SOME sort of signature on your posts.

| There's not much the Asrock bios allows me to change. The CPU
| Multiplier is locked at 10x. The manual has just 6 lines discussing

|
| N.B. The cpu doesn't get much running as it doesn't POST. So temp
| values are moot. Using standard cooling system that came with the CPU.
| CPUZ reports:
| Asrock Conroe 1333-D667 Mobo with chipset Intel i945G/GZ Rev A2
| Southbridge Intel 82801GB (ICH7/R)
|
| Bios AMI P1.30 07/17/07
|
| Factory settings are Auto, CPU Freq 200MHz. 100MHz PCIE. Core voltage
| is 1.208v. At standard clock the cores are 41C, CPU 38C, according to
| Speedfan. Ambient is 20C.
| DRAM Freq 266MHz, FSB

RAM 3:4, 4-4-4-12, PC2-5300 (333MHz) 1.8v
|
| When I run at CPU Freq 210MHz in Sync mode CPUZ reports:
| Core speed 2100.5 MHz, Bus 210 MHz, Rated FSB 840 MHz
| DRAM Freq 280.1 MHz, FSB

RAM 3:4, 4-4-4-12
|
| And at CPU 220MHz:
| Core speed 2201.5MHz, Bus 220.2MHz, Rated FSB 880.6MHz
| DRAM Freq 293.5MHz, FSB

RAM 3:4, 4-4-4-12
|
| And at CPU 230MHz:
| Core speed 2300.5MHz, Bus 230MHz, Rated FSB 920MHz
| DRAM Freq 306.7MHz, FSB

RAM 3:4, 4-4-4-12
| Vcore 1.21v, Cores 43C, CPU 39C running SETI.
|
| Looks like the RAM may be the cause of the problem as the CPU doesn't
| POST past 240MHz. If so, what should the settings below be to permit
| the RAM to overclock:

| >| VDDQ Voltage: Auto/High/Low
|
| Your ideas please (other than buying some 667 RAM)?
|
| Thanks.
