Difference between LGA775 Xeon CPUs and its desktop counterparts

hi there,

if somebody could throw some light on this please:

what are the differences between LGA775 Xeon CPU´s and its desktop counterparts, such as Intel Xeon UP E3110 and

 

Intel Core 2 Duo E8400?

also i´m wondering if a 1:1 FSB:RAM Ratio would be the way to go for me as i´ve got 667Mhz ram modules - so i would need a 1333FSB CPU?

thank you

Hope this helps a bit. As personally, i dont know much on the Intel Stable Image Platform & Intel Trusted Execution Technology.

Kind Regards,

thanks for your quick answer

that is quite remarkable as the Xeon E3110 is more expensive than the E8400 - so it seems that the E8400 is the better choice?

could you throw some light on the FSB:RAM Ratio thing?

i´ve got an Intel S3210SHLC board, as i´m not able to tweak anything in the bios i´m wondering if a 1:1 FSB/RAM ratio would be the most efficent setting?

to achieve this, i would need a 1333FSB CPU for my 667Mhz Ram, is this correct?

thanks in advance

Hi there,

Let's consider a CPU E5410 in this example.

The Xeon CPU has:

 

Speed 2.33 Ghz

 

FSB 1333 Mhz

So here the core frequency to fsb multiplier will be 1/7. [(2.33x1000x4)/1333]

If i am using a memory with speed 1333Mhz, then the fsb:dram ratio will be:

1:1 [1333/[(1333/4)x4]]

Now if you are using a memory with speed 667Mhz, then the fsb:dram ratio will be:

2:1 [667/[(1333/4)x4]]

I think so. I am not 100% sure.

Please investigate further.

Kind Regards,

 

Aryan.

i calculated it this way:

as Intel´s FSB is "quadpumped" (1333 / 4 = 333,25) i thought that the effective DDR2 frequency (667 / 2 = 333,5) would achieve an 1:1 FSB/RAM ratio

in the end - imho the most efficient setting, or?

maybe another person could chime in here?

is my calculaton correct?

CPU: (1333 / 4 = 333,25) ; DDR2 frequency (667 / 2 = 333,5) = 1:1 FSB/RAM ratio?

aryan, your computation confused me a little

in respect of "Intel Trusted Execution Technology" and "Intel Stable Image Platform" it seems that it isn´t quite important to me

i´m more concerned about the 24/7 capabilities of the E8xxx and Xeon CPUs (LGA775) - are there any drastically differences?
