What would be better

there is a good chance the motherboard simply does not support any of the core/core2 cpu lines. back when the 820/830 and 840 were around, we had 945 and 955 chipsets, and the core2 wasnt even in the picture. core2 uses same socket but requires a different voltage regulator spec...so , like i said, good chance you are stuffed.

So a new mobo and proc probably. Not a bad thing if they all fit into the Dell case. What are the chances though... Sheesh
 
I'm running a E4300 on a 865 chipset, which is ancient coz my old P4 478 had the same chipset.

See if you can update the bios for it
 
Which case do you have? I don't see why it wouldn't fit a new mobo. They're pretty standard sizes.
 
If its an old Dell, there is every chance they won't fit as Dell do custom design some stuff.

yes, the mobo manufacturers are able to rectrospectively add features to the older chipset designs to get them up to core2 spec. but as you yourself said, your 865 wasnt a 865 that was made when 865's first came out.

on original designs, 865 and 875 was skt478 ddr
915 was skt 775 ddr or ddr2, same with 925 (although i havent seen a 925 that uses plain ddr, only ddr2, so perhaps this SKU was never made)
955 and 975 was skt 775 ddr2, first designs to support DUAL CORE smithfield Pentium D cpu's.

later 975 designs were the FIRST EVER to support Core2. (the intel 975xbx motherboard, from revision 3 iirc)

refinements were then made to older chipsets, and it is now common to see core 2 support on 945/946 motherboards, and even older "chipsets" in newer motherboards designs, as you have.

but this proves nothing, as i take it the original poster bought his machine as a complete unit, mobo+cpu already fitted and working and warrantied from Dell, at a time when Pentium D was current tech, so my statement still stands.
 
Well my board takes AGP and DDR and only supported P4 6xx series when it first came out.

After flashing the bios a couple of time, i upgraded from a P4 631 to D820 to a E4300.

I'm noy saying u're wrong but flashing the bios could be a solution...if Dells are even flashable
 
Yeah, as mentioned earlier on in this thread the Bios is on A03 which is the latest.

I fear Dell has hard coded the mobo to accept only this proc:(
 
Have you done the bios update? Maybe use cpu-z to get the chipset of the mobo and then we can take it from there...
 
I have done the update, I will post the chipset once I get the thing installed with XP.

I've tried calling Dell SA in Jozi for advice/assistance but because the machine was bought in the US they wont help me. The Dell community forums are down as well:(

Funny thing is as well is that with 8GB Ram in it it will boot fine with XP (obviously wont see 8GB) but with Vista x64 it wont boot at all.

It also has an Ati Theater 550 Pro card in it.
