SE7501HG2. Can it run the E5-1607 v2 Xeon?


My board is nearly 10 years old. In the Intel pages, there is one which lists Server Products, and for the SE7501HG2 there is a list of "Supported processors". Intel� Server Board SE7501HG2 — Supported processors

To my big surprise I find brand-new Xeons in that list, e.g. under 3.00 GHz the E5-1607 v2.

Q.: is it really possible to upgrade that old board to a brand new Xeon?

Should the answer be yes, that would really please me.

Sadly, no, that won't be possible. If you look at the rest of that table, the 3.00GHz must also have a system bus speed of 400 MHz, and the table even provides the order code of the one that works.

I can see why it would be misleading, since the url runs a search on ARK for "Search.aspx?q=3.00%20GHz", which just returns all possible processors that have that speed.



Thank you very much. However, I am not familiar with "system bus speed". In the server-board product specification it says: "The Intel Server Board SE7501HG2 accommodates one or two 400MHZ FSB or 533 MHz FSB Intel Xeon processors with 512 kB L2 Cache via two SKT604 604-pin ZIF sockets." Thus there is at least some speed mentioned that agrees with the one you cite.

Do you refer to another speed?

Furthermore: The text above the tables of the above mentioned links says, and I copy the text:

"Note: All processors listed below are supported by the Intel® Server Board SE7501HG2."

Could you please indicate a bit more clearly why I have to give up my hope of being able to upgrade the processors?

Dan O is correct,

The FSB (front Side Bus) which ran at 400Mhz or 533mhz between the processors & the North Bridge chip which connected to a memory controller and a south bridge chip to PCI slots, Network controllers and HDD controllers.

In 2008 the QPI bus replaced the FSB and opened a new leap forward in processor speed

QPI buses run speeds up to 8 Gigatransfers per second. The features of a North Bridge are all inside the CPU as well,

Not enough yet?

The old Xeon's in your board have 604 pins that plug into the board,

The E5-1607 (which is not a dual CPU processor) has 2011 "pins" on the mother board that connect to pads on the CPU. (reversed)

Intel has a Tock \ Tic strategie so that customer can upgrade a board's CPU. This means when they design a board for a new CPU, (the tock), about 1 year later the Tic CPU releases and is usually a drop in replacement as far as the hardware is concerned. In the current CPU's the E5-1607 would be the Tock and the E5-1607v2 is the Tic. The computer technology leaps ahead so fast that the CPU's that come after the E5-1607v2 are going to need new mother boards to support the newer features.


Thank you both for clarifying the matters; especially the interesting details that follow "Not enough yet?".

Case closed.
