Best 800MHZ FSB DUAL/QUAD CORE CPU

[Khaleal]

Hi,

What is the best 800MHZ FBS dual/quad core LGA775 CPU?

 

[unknownofprob]

I'd get the quad core LGA 775 Processors.

Intel Core 2 Quad Q8200/Q8400 are good options.

What is your motherboard?

I'd get the quad core LGA 775 Processors.

Intel Core 2 Quad Q8200/Q8400 are good options.

Those are 1333 FSB.

Q8200/Q8400 are both 1333MHZ FBS.
The problem is that the mobo in the PC I'm trying to upgrade supports 533/800MHZ FBS 🙁

What is your motherboard?

Intel 945GC. It came with a Lenovo 3000 J200 9691 34G desktop.

 

[unknownofprob]

yeah i know, I was just listing 775 processors. but i just saw the 800MHz FSB, woops.

what is your motherboard?

According to this website: http://www.cpu-upgrade.com/mb-Intel_(chipsets)/945GC_Express.html the best is the E4700 core 2 duo.

The Intel site also says E4700.

The Intel site also says E4700.

Thank you.
BTW, What will happen if I install a 1066MHZ FSB CPU like E6600 with this motherboard?

 

[unknownofprob]

Occasionally a motherboard will boot with an unsupported CPU (higher FSB), but I would be very cautious as this is usually unstable

 

[rehed21]

If you have an E6600 laying around you can try, but like unknownofprob said, it's highly unlikely that it would work, especially on an OEM/Intel board.

Thanks a lot guys.. I've upgraded to E4600 2.4GHZ from E2160 1.8GHZ and I can feel a difference especially in games (The 2MB L2 CACHE made the difference)..
Some guys told me that I can overclock easily to 3-4GHZ.. Does my mobo support that? And will it work with the stock cooler?

 

[rehed21]

You would have to check your bios options to determine if you can overclock, Lenovo might have locked those options. Can you increase the front side bus and voltages, or is there a "burn in" option? An aftermarket cooler is recommended if you want to overclock due to the higher temperatures it causes.

 

[Khaleal]

No I can't find these options. Is there any way to OC this CPU (By unlocking the BIOS for example)?

 

[rehed21]

You can try overclocking with software - ClockGen is one program. There is no way to unlock the BIOS.
