Hello experts,

Normally working with Dell, i have a HP server ML350 G6 where i need to add a second CPU. I order 1 that i was thinking the same but the supplier says if it is not working it is a power issue..  there is a 60 and 80 watt CPU..  I order a second CPU with the same part #, i'm sure i have 2 identical CPU.   But i also have the problem.

As you can see on the picture, the second light from the right is flashing red. the fan are running faster than usual.  No POST or bios access possible.

Is there something i'm missing toggle switch, power module that i need to add, Jumper????  

Any help appreciate.

Rather a different shape between a DL380 and a ML350, any chance of a photo with the lid off rather than just the LEDs on the front?

did you confirm the other items in my link?  there are specific numbers on the processor that must match.

not just part #

Can't see any bent pins. I would remove the new RAM and borrow a stick from CPU1 to eliminate that possibility since you know the orignial sticks are good. Also if you have spare thermal paste I would prove the new CPU works by putting it in socket 1.

stick are brand new..  24Gb per CPU.   I already test each CPU, in socket 1 and they are working in a "single mode"

When you add a second CPU you need to add a second fan and the memory may need to be moved around or memory may need to be added.
 Bent pins will usually throw a memory error on the screen

Ok, got your answer...

per HP, you must update the BIOS to support the CPU.

This must be done PRIOR to installing the CPU.

Good Luck!

no fan needed for ml350g6

update the bios to the latest revision, or use the jumper or switch on the board to clear it.  I recommend just flashing it to the latest

Take a look here
http://h18004.www1.hp.com/products/quickspecs/13241_div/13241_div.html
But see the attached file as well
You will have a total of 4 fans doing push pull across the memory and processor.
When you install the second processor you also install, Heat Sink, Fan, and memory shield.

Not so, BIOS update is sometimes required to support later CPUs but it is not generally needed to support a second CPU of the same type. Still, it won't hurt.

There is certainly a 2nd fan included with the CPU kit but I thought that was already installed?

YES SO andy - I spoke to an HP rep directly who advised either clearing the bios using the switch/jumper would work (if the bios was new enough to support the processor) or just outright flashing it.

Dont naysay what you dont know.
