BIOS doesn't read the RAM SPD module correctly

Hi,
I need your help.
I was upgrating my old system by replacing some dead RAM by newer one.
The chipset is an intel 865 (MOB: D865GLC). The rAM are DDR 400MHz (Kingston).
I check that these RAM were supported and verified by Intel for that MOB.
When I install the 2 chips (512MB each) the bios could not recognize the frequency at 400 MHz and setthem up at 266MHz. I try to manually correct the spedd and timing but the I could not reboot.

Usually, it means that the SPD module is not read correctly and that the RAM is defected. In that case I try each RAM independantly and same result!

So I used CPU-Z to read the SPD module to see if it was really the RAM, but here the SPD was read correctly.

I made sure my bios was up to date and I got the last version.

Is there anything I can do to fix that?

Thanks
Fef

Hi r-sky,

From CPU-Z: bus speed (CPU) is 99.8MHz and FSB rated = 399.1MHz

Although I do not know much, when you say the system is not only the mainboard? I though the RAM frequency has to match the the MODB chipset capability not the CPU. Am I mistaken?

I have a Pentium 4 @ 2.2GHz.
In the manual they mention it on table 5 with FSB at 400MHz.

At the same time their reference for DDR400 is FSB 800MHz and read spead 400MHz.
Does it mean that th ebord has to have a FSB of 800MHz to be able to have the speed at 400Hz?

Thanks to both of you r-sky and Allhands. I finally got it!
