Dear Raptors,

I have a problem that is partial described in topic title. I have AB9 Pro motherboard and I'm trying to put a C2D E7400 CPU. But it looks like that CPU is not supported. But I found on some forum that some dude flashed his bios with beta bios and that it worked for him. I tried it to do the same but for me still doesnt work. My post code shows me 8.7 and after 10 seconds it restarts and like that forever.
So my question is, is it really possible to run E7400 on AB9 Pro and how, or it is just my imagination :(

thank you very much

which stepping?

[Broo]

I dont know what that mean. fck :(

[Broo]

aha, okey, I google it and it is R0 stepping.

[Broo]

Buff, what about the stepping. what to do what to do!? please.

Are you sure its R0? Stepping is listed on the packaging for the CPU, might even be listed in the numbers on the cpu itself.

What CPU did you use to flash the BIOS chip with? Did you clear the CMOS after the flash?

hi, now I will write all that is on my CPU:
Intel 06 e7400
Intel Core 2 Duo
SLGW3 mala
2.80 Ghz / 3Mb / 1066 Mhz / 06
Q934A121

I flash bios with my Intel Pentium 4 3.0Ghz
Is that bad?
and I reset the CMOS

Hmm. Oddly Intel does not list the CPU...it does list two others but there are supposed to be three flavors of the one you have.

According to the manual. 8.7 means Check CPU voltage.

You manualy reset the BIOS using the CMOS jumper and not just the /cc switch when flashing correct?

Try disconnecting all cards, other than the vidcard. Remove all but 1 stick of RAM, and disconnect all other power using items from the CPU.

Make sure the CPU fan is connected to the CPUFan Header.

[Broo]

everything unplugged only CPU fan is connected and still it shows 8.7. code. But when I put Intel pentium 4 3.0 ghz everything is fine.
This problem is only on E7400..
Any new advice? ..please

You can try the memory swap trick.

Turn off the AUTO setting for the CPU with the older CPU in. Manually set the correct voltage for the CPU and the speed....Then save the settings and shutdown. Then swap the CPU.

What it could be is that the CPU is not being IDENTIFIED in the DMI table. This might need something like a BIOS hack, where you pull the DMI table from a different motherboard BIOS and then replace it in the BIOS file your using.

if your CPU is an RO you may well be SOL ...
