945gc chipset limitations

i recently purchased a motherboard with a 945gc chipset. On the intel website it say it has a 800Mhz FSB and DDR2 667. Does this mean i will not get them most out of my duo for 2.3Ghz processor with 1333Mhz FSB, and 800 Mhz memory? If so, what are some standard chipset that will take full advantage of my components. Thanks for the help.
 
Did you check to see if your motherboard supports the Core 2 Duo? I know many if not all of the 945-based motherboards do not support the Core 2 Duo's with a 1333MHz bus speed.

I would recommend the P35 or the X38 if you don't mind spending quite a bit.

I am pretty sure it supports a core 2 duo. Its a AS Rock Conroe 1333. My question is that on intel it says the chipset has a 800Mhz FSB and supports 667Mhz ram. But the motherboard advertizes it supports 1333 FSB and 800MHz ram. I am confused.

The site says the following:

"FSB1333-CPU will operate in overclocking mode. Under this situation, PCIE frequency will also be overclocked to 115MHz."

I checked the Intel site on the 945G and it said the following:

"1066/800/533 MHz System Bus
Supports Intel® Core™2 Duo processor, Intel® Pentium® D processor, Intel® Pentium® 4 Processor with HT Technology and all other Intel® Pentium® processors and Intel® Celeron® processors in the LGA775 socket, with scalability for future processor innovations."

So it seems like that board will support the Core 2 Duo's, however processors with a 1333MHz bus, the motherboard needs to overclock the bus speeds in order to operate at that speed.

My chipset is 945GC, different from 945G, which i believe from the site has a 800fsb. In addition, would the motherboard overclock automatically, and is this bad?

The chipset that was listed on the ASRock website was 945G, not 945GC.

Well, i guess the company i got my barebones kit from got a lot of stuff wrong. They said 945GC chipset. 800Mhz ram, which i a pretty sure it cant handle, only 667Mhz ram. Will my computer achieve the 1333FSb, and if so does it happen automatically or do i have to manipulate something. Also what does this mean "PCIE frequency will also be overclocked to 115MHz" I bought a 550 watt consumption pci express video card. Is there going to be a problem. People said that my Echo Star 600 watt power supply was a bad company. What complications could occur here.

It will work with DDR2 800, although it will slow down to run at DDR2 667.

I'm not completely sure on the "automatic overclocking", it seems as though it's automatic when you use a CPU with a 1333MHz bus speed, it will automatically raise the speeds in the BIOS for it to run at that speed, which may in turn overclock your CPU as well.

As for the PCI-E bus speed, It's generally not a good idea for it to be over 100MHz because it can cause instability, however 115MHz isn't too high, so it shouldn't be a problem.
