Oops yep KB sorry mate missed that and while I am here (off to work in a tick) I found the G Skill site was more helpful re sorting this out than the Asus one as most of the stuff I can afford at the moment are listed as suitable for the Z77 chipset.



Sorry wrong board

Whut?
Intel FSB is 100MHz on Sandy and Ivy Bridges.

I meant cpu fsb . .
like
that are for e.g
800mhz for e5700
1066mhz for e7500
1333mhz for e8400

Sorry beret but still don't know what you mean as there is no ref to the bus speed in this ARK | Intel® Core

plus I see it states 1333/1600 memory speeds so am even more confused now.

Plus this has me thinking I ought to reconsider my options re the CPU if 1600MHz is the top speed that I can put in - it's all getting a bit too complicated now

Intel I5 3570k bus speed questions. Please help

I aint expert but i studied in computer architecture that fsb " front side bus" is the main link of ram to cpu so best choice is to match their speeds . . . . .

For example

If a one worker has to carry one brick at time to a room i.e. your CPU and there are 160 bricks and 133 workers
some workers have to do double work (WORK BEING SLOWED)
If a one worker has to carry one brick at time to a room i.e. your CPU and there are 133 bricks and 160 workers
some worker have nothing to do (WASTE OF HIRING more)
So the best way will be to have equal number of bricks and workers . . .

Same way send data to your cpu which it can accept and work at efficiently ..........

Might be a boing story but i think it will help

Yes beret I sort of get it from looking at this Front-side bus - Wikipedia, the free encyclopedia the bus you are speaking of is the total of the caches being channeled to the chipset and then to the RAM.

But if the FSB is set at 100MHz unless clocked higher somehow then the transfer rate to the RAM from the chipset will also have to be held at the same rate? Now taking that I want to use 1866MHz RAM how am I going to achieve that speed from the chipset to the CPU? if the transfer rate (1866MHz) is achievable (as it is confirmed by the Asus site specs) from RAM to chipset?

That is a lot of speed difference my friend

It is going to be an i5 3570K on an Asus P8Z77-V board. The problem all along has been that any RAM I can get reasonably easily and at a reasonable price does not have my Asus board compatibility - listing it as certified to run on that board. Z77-V PRO, Premium, LE, L etc etc do but as you can see my board is a plain -V.

If i am not wrong !
i5 3570K processor memory specs show that it can give max performance with 1600mhz DDR3 .. . . .
Any thing above that will work for sure but wont give the performance it is made for !!!!!!!!!!!!!!!!!!!!!

The Jedec standard for Ivy Bridge is 1600MHz, not max performance. They don't go by FSB anymore like they did back in the day.

As for the RAM being compatible with that board........that is one of the most popular Z77 boards around, find some GSkill or Corsair and it will be compatible.

I think there has been a disconnect somewhere so I will attempt to fix it.......Get the Corsair 16gb 1866MHz 9-10-9-27 kit for less than $100, you can decide whether you want it in blue or black.

The End
