You wont be able to even run a Q6600 on that board the 945G chipset doesn't support quad cores the best you can do is an older E6xxx and you have to make sure its a conroe not wolfdale. Conroes are 65nm and wolfdales are 45nm your boards chipset doesn't support 45nm either. So no quads and no 45nm. Your best bet would be to change motherboard out too. You can go an AMD Phenom II x4 fairly cheap you can do motherboard and processor for around $200. Now trading up to an E6xxx will give you a huge performance boost over the Pentium D, even though the Pentium is a dual core it doesn't run efficiently at all a core 3 duo will give you id say around a 150% boost in performance.
Good luck with it you may have to update the bios but it should work with out the update. Also remember to clear the cmos before installing the new CPU just take the battery out of the motherboard for a minute this will reset the bios. Again Good Luck
I've got the new cpu in and followed all the instructions but its not coming on properly. The power supply and lights are coming on but i'm getting no picture, hd sounds like its coming on but the processor and case fan are completely still. I've got everything hooked up and took all the normal precautions - static etc. Any advice? Is there something I'm missing?
You might be able too but first when you put new CPU in did you make sure you have the most up to date bios and also did you reset the bios by takeing the battery out the motherboard for a few minutes.
I am sorry that that processor didn't work out but in all seriousness If you have to get a new motherboard ditch that E6600 you should be able to resell that on ebay for exactly what you got it for no problem.
That motherboard you listed will fit but you might have problems with the front panel connections. But IMO sell the E6600 and get a AMD athlon II or a Phenom II you can get an x3 or an x4 chip for the same price you are paying for that motherboard and processor. You should also be able to sell the pentium D 920 for a little too.
Well your using a HP case so it can cause some problems in replacing the motherboard in it since the front panel connections are meant for that board. So if you do want to upgrade my suggestion would be to find a cheap case and use all the components from the hp except the motherboard of course.
cool. sure cheers for all the help, i've a good idea what i need to do now so i'll just do a bit more reading and decide exactly what i need. I might just go for a complete system upgrade down the road instead... my original plan was just to extend to life of my current system, but now that i'm seeing the limitations of what i have, i might have to rethink my plan
