Itanium2 "DP" processors in Intel SR870BN4 quad server

Post by echo5julie » Thu, 16 Sep 2004 23:27:04


I am suffering under some confusion, hopefully someone can clarify.

I have an Intel SR870BN4 quad cpu Itanium2 server. It currently runs 4
900Mhz/1.5M processors.

I pulled the processors and put in two 1.4Ghz/3M processors. Upon power
up the machine just beeps at me. No EFI, no bios.

The proocessor's SPEC number is SL7FP.

The bios is updated to the most recent 9.1 revision. In reading all of
the documentation I cannot see anything about certain I2 processors not
being supported by the 870 based system. I have tried single proc as
well as procs in different positions. Single proc in CPU0 as well as
two procs in CPU0 and CPU1 do not work.

In looking over Intel's website I can see where Intel mentions
"Optimized for DP" and "Optimized for MP" yet I cannot find any
specific part number that says whether SL7FP is a "DP" or "MP"

Can anyone shed light on what might be keeping this from working?

It might be that you don't have the correct firmware. I assume the BIOS
9.1 is something the motherboard requires (I'm a chip guy so don't know
that much about the boards). The processor itself also requires a
firmware. Each stepping of the processor requires a specific firmware
version (this includes what are called PAL and SAL and is essential to
power on of the microprocessor). If you are manually swapping CPUs
around, you will probably have to manually find and apply the firmware
update to support the exact stepping of Itanium 2 you are using. Since
your old chip was a "McKinley" and your new chip is a "Madison", you
will definitely need to update PAL.

The SL7FP identifier is not familiar to me. Intel's web page lists
1.4GHz/3MB versions as both DP and MP products. So just knowing the
speed and cache isn't enough and since I don't know that code, I can't
help you here.

My words are my own. They represent no other; they belong to no other.
Don't read anything into them or you may be required to compensate me
for violation of copyright. (I do not speak for my employer.)

Keep in mind I have no idea what I'm talking about, but if Intel did a
single, dual, and multi thing like AMD, they may not match the BIOS
looking for an MP part.
