Core 2 Duo Installation Woes

[coolego1]

Hello All,

I have an old Gigabyte GA-P35-DS3P LGA775 Motherboard that, up until now, has had a Pentium 4 3.4 GHz Prescott (single core, gasp!) in it. This evening, I went to a local parts store and bought a C2D E7500 to try to squeeze a bit more life out of this machine...

After removing the old CPU, I cleaned off the heatsink (Zerotherm BTF90) and dropped in the new chip. I applied the thermal paste, and screwed the heatsink back on. I went to turn on the system and... Nothing. The case fans started spinning for about 3 seconds, and then the whole thing turned off, the whole cycle repeating about 4 seconds later until I manually turned off the power supply (Antec 500W Earthwatts)

I tried to reseat the processor and disconnect all peripherals, but that didn't work. I then put the old processor back in, and that works fine so I assume I didn't bend any pins or anything.

Is it something with the voltage on the processor that could be causing this? I believe that the C2D uses less power than the P4, but I don't know how to change that if necessary. I think I will try the stock heatsink tomorrow if I can't get this figured out, and then I'll have to resort to the idea that it might be a lemon...



System:
Gigabyte GA-P35-DS3P LGA775 Motherboard
Intel P4 3.4 GHz CPU (now) --> Intel C2D E7500 (hopefully)
2GB Patriot Dual Channel DDR2 800
ATI X1950XT GPU

Check the manufacturer's website for list of supported CPUs for that mobo. You might need a BIOS update.

Need to upgrade to Bios F11 for that processor to work

Yep, seems most probable. Looking at Gigabyte's site, it looks like you have BIOS version F8. You need at least F11 to get support for the C2Ds.

There are four revisions of the board, but since I was bored I cross checked them all and determined they all share the same BIOS. But if you want to check your revision anyway just look on the board itself, usually near the socket. It should say what revision it is.

Edit: damn, took too long. oh well

I had a problem upgrading my second desktop rig, from an E2140 to a Q9300. I am using GA-P35-DS3R v1.0 mobos. After I installed the new CPU, it went into a reboot loop when I tried to power it on. I just needed to clear the CMOS. Then it booted. So then I immediately flashed the BIOS to the newest one. (F13 final, was on some beta of F13).

and dont throw away your old chip, you prob need it in to flash before you put in the new chip and since you already tried the new cpu with the old bios, you may wish to do a "full" cmos reset

Thank you everyone for the responses! The BIOS was exactly what was wrong. I have HW Revision 1.1 and I was on BIOS version F4(!). I upgraded to F12 and installed the new processor and everything is working perfectly. Now to think about overclocking...

Don't think. Get to it
