Stupid overclocking question

[shaggy77]

Hi,

I got a stupid question. I have an E6420 that is overclocked to 3.2 GHz. With the memory running at 400 MHz that means my FSB is running at 1600 MHz. The chip is 1066 MHz FSB. The MB is 1333 MHz FSB. What actually happens? The CPU and MB are dynamic in allowing the additional data? Is it more or less 1066 is the official support speed but the bus is more accommodating to the traffic.

Alliteration.

The Motherboard is an 8 lane highway. The CPU is 6 lanes of traffic. When the over clock kicks in, it is like 12 lanes of traffic. That's how I would look at it.

if you need system spec, look at the signature.

CPU max official bus 1066
Motherboard max official bus 1333
Your bus 1600

1066 = 2.0L engine
1333 = 2.5L engine
1600 = 3.0L engine

It is all based on the FSB speed. The speeds you listed are the rated speeds - the MB supports 1333 FSB processors (quad pumped, so really 333), while the memory is rated at 800 DDR, which is 400 FSB. So if your FSB is set to 400, your memory is running in spec at 800 DDR, whle the motherboard is over-spec at 1600.

That's is assuming that your memory is set at 1:! with the FSB, gets freakier when you use dividers to run the FSB higher than the memory can go.

Hi,

Thanks for the answers. I just had this weird thought in my head about it. To me, I was thinking of the FSB being that highway at rush hour. (60% more cars on the highway all the time) I was trying to think how over clocking a processor is really helpful if the weakest link in the chain (in this case the CPU) was really the part that holds up a 1:1 ratio.
