I have just built a system based on the P4C800 C Deluxe
I installed Kingston "Hyper" PC3200 KRX3200AK2/1G
I obtained boot code error of 3 beeps/ Memory
I swapped out with a known good Corsair 256 XMS (non DDR)
I booted to fine.
I was told by Kingston Tech that the Hyper can be used in this board.
So my question is do you think that both sticks are bad or are they not
compatible with this board.
If not what is a good comparable DDR with good speed.
I do not want to get a RMA and buy the same ones if they are non compatible.

Thanks
Don

At first I thought your "KRX3200AK2/1G" was a typo.
I looked in the branded section of the Kingston site.

Those are registered memories! No wonder you got beeping.
A way to verify they are registered, is if there are three
smaller chips mounted somewhere in the center of the module.
One chip is a PLL and the other two are register chips for
registering the address etc.

The manual says:

"These four 184-pin DIMM sockets support up to
4GB system memory using unbuffered ECC or
non-ECC PC3200/PC2700/PC2100 DDR DIMMs."

KHX3200AK2/1G is a pair of unbuffered non-ECC PC3200 2-3-2 memory

KVR400X72C3A/512 is an unbuffered ECC PC3200 3-3-3 memory

ECC is useful if you are running a server, as a single error can
be corrected by the syndrome. If your system is a desktop, you
might be better off with the faster, unprotected memory, as error
rates on DDR are pretty good.

Return the memory and get some unbuffered to replace it.

HTH,

Thanks Paul,
I called Kingston Support and they never mentioned this when I spoke to them
Do you mean that the KRX3200AK2/1G are EEC buffered and not
"KHX3200AK2/1G is a pair of unbuffered non-ECC PC3200 2-3-2 memory"
What is a good memeory and timing for this board.
Thanks

Don,

Hold your horses for a second....

The P4C800 is supposed to take ECC Ram - this is one of the benefits of the
Intel 875 chipset over the 865.

Now, you might be having troubles if the bios was not set to SPD in which
case it could have started by using much too tight timings...

If you decide you do want ECC (slightly slower system, but more reliable)
then perhaps persist a little. You will want to enable the appropriate ECC
option in the bios to take full advantage. (Paul posted about this in detail
recently).

I would set the bios to SPD using the working config, swap to the new RAM
and give it a go.

ECC is no where as expensive as it used to be, but it is still at the pricey
end of things, so using this memory may not be want you want or intended.
