Stupid question regarding OC and FSB

My motherboard is 1333 FSB, the chip I want is Q8300 which is rated at 1333 FSB. Since at it's default CPU it's already at the max FSB that my motherboard can handle will I not be able to over clock it? Where if I get the Q6600 it has a standard of 1066 FSB (I think) which would get more room to overclock?

Do I have this all wrong? It's complicated for a noob.
 
A very good question actually.

You can probably still overclock, the difference is you'll be overclocking the chipset AND the processor, so you probably won't get as high of an overclock becuase you'll hit a FSB wall a lot sooner with the Q8300 with it's high FSB/low multi configuration.
 
You'll have to increase the FSB speed to increase your CPU speed, which is totally doable. I can't remember my FSB speed, but I was able to overclock my E6400 from 2.13GHz up to 3.3GHz by increasing my FSB. A +1GHz OC might be a bit much for your setup (maybe not, I dunno) but you can probably crank your FSB up a good bit and get some extra speed out of your processor.

I would find a tutorial for overclocking with your particular motherboard. Just because your FSB is 1333MHz doesn't mean you can't push it much higher.
 
Q8300 you'll have to increase the bus clock to 400MHz (after quad-pumping = 1600MHz FSB). Assuming you leave the multiplier to the max (7.5 for that chip) that will equate to a 3GHz OC. Of course, this is assuming 1) you have a decent P35/X38 mobo with BIOS update for 45nm Core 2 chips, or a decent P45/X48 mobo. 2) Your chip will accept the volts required to hit such an OC. 3) Have an after-market cooling solution that will help cool it.

However... if you're using that GA-965P-DS3 in your sig... that's a big problem. That uses a P965 chipset, and if you look on gigabyte's website, the best quad-core chips you'll be able to use are the 65nm ones (QX6850/6800/6700, Q6700/6600).

Q6600 revision G0 chips were great overclockers, and could very easily accept a 400MHz bus with the right amount of voltage and cooling. Q6600s also feature a higher 9x multiplier. This would equate to a 3.6GHz OC. However if you keep the bus clock at 333MHz (1333MHz FSB) and keep the multiplier at 9... you should be able to have a 3GHz OC without changing the voltage at all!
 
Thanks for the replies, I will definitely stick with the Q6600. Just picked up a Coolermaster 212 Pro. Now i just need to find a deal sub $55 on the processor. I should be good for a couple more years for what I do.

Hope you find a good deal! Do you mean 212 Plus? If ya do, it's a really good heatsink (especially considering the price), have fun. :)

Are you just going to do a 333MHz bus speed overclock or going to try for more [if you can]?

Also, gigabyte's website doesn't say it's supported... but it just might. Could try finding a Xeon X3220... it's exactly the same as the Q6600, just a different name. People don't search for those as much so you might be able to bid on one real cheap on ebay. Could be worth a shot if you want to be adventurous.

Well as far as the overclock, it depends on what I really need. I want to play planetside 2, and I have actually been able to play a little with my e4300 clocked at 2.5. As for the Xeon X3220 I had never heard of it as I was going off the list that is supported for my motherboard. It's very interesting how steady ebay prices are, there aren't really any steals of a deal, every processor always has watchers, I just can't believe theres thousands of others looking for old processors. I think just maybe that the enthusiast crowd is the minority.

This is what I was going to follow up with on your other thread. Because you have an older chipset an unlocked multiplier will do wonders. Good luck with the OC. Btw, what's your power supply?
