Will C2D work with this motherboard?

My in-laws have a Gateway 840GM. Currently has a Pentium D 830.

CPU-Z says the motherboard is a i945G/GZ. Bios date is 7/7/05.

When I go to Intel website they say 945 chipset supports C2D BUT did they support them from the beginning or was a bios update neccessary. I have searched the web and Gateways website looking for a bios update and nothing to be found.

Thanks for looking.
 
Found a BIOS update...

Go to ftp.gateway.com and browse to /pub/hardware_support/bios/pentium/pb94510j/

Readme's don't say anything about support for new CPU's though.

I think you're fine for Duo's, but not Quads. I went and looked at the CPU support list for a Gigabyte mobo with the same chipset. It supported the C2D from the original PCB revision and BIOS from what I could tell. On Asus's site, all but the very first 945G board supported C2D's.

I know it's still not a 100% answer, but it's something to go on.....
 
wow

Too cool man. Thanks I'll go check it out.

Guys over at had me convinced no hope. Kinda convinced myself too.
 
How did you find that?

That was the actual update for this motherboard.

I now have a bios date of 4/20/06. But like you said, it makes no mention of adding support for new CPU's. Just a flash drive bugfix.

I think I have a shot now though.

Maybe pick up a cheapy C2D off of FS/FT and see what happens?
 
The essential requirement is the volatge regulator module meets the specification VRM 11.0 that was released in June 2006. Needless to say, 840GM is too old to meet VRM 11.0.
 
Went on wikipedia to look up the release date for C2D and sure enough there was a reference to the VRM 11.0.

BAH!

I really thought they came out before July 06 but I guess not.

But isn't motherboard support usually built in way before the proc releases?


 
Here is Voltage Regulator-Down (VRD) 11.0 Processor Power Delivery Design Guidelines. The official initial release date is June 2006. Core 2 Duo was released on July 27, 2006.

There are many motherboards with chipset released before June 2006 (e.g. 945G/P) but that support Core 2 processors. All of them were manufactured after June 2006 with new VRM. For example, MSI 945PL Neo does not support Core 2 Duo with PCB 1.x but supports it with PCB 2.2. There are also plenty of 945 motherboards that do not support Core 2 (VRM 10.0/10.1!).
