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.
Supported system bus frequency and memory speed combinations
To use this type of DIMM... The processor's system bus frequency must be...
DDR400 800 MHz
DDR333(Note) 800 or 533 MHz
DDR266 800, 533, or 400 MHz Supported system bus frequency and memory speed combinations
In order for you to use DDR400 you must have a FSB of 800MHz. Since your FSB is 400 it will be reduced to DDR266. Don't forget that DDR stands for Double Data Rate. In other words DDR400 has an effective speed of 800 MHz. Since your FSB is 400MHz DDR400 is actually twice as fast.
