I am now.
did you read the service manual first.
mine has matching SLBV4 cpu,, see link below.
both with matching CPU, and with working fans, (plugged into correct fan power jack for speed regulation)
the 2 ram banks for CPU and matching and in correct slots. i bet you forgot RAM for CPU 2?
once correct, BIOS clearly shows both processors.
i get the same speed seen here. cpu Assmark 2xCPU =10053!) (smoking fast)
NO warranty answers by me.

thank you .
i have exact same cpu both are x5670 and work in socket 0 . ( none of them work in socket 1 !!! is it normal ?)
but my cpu fans have 4pin cable ! but board connectors are 5 pin !!
and i put ram (which is the same ) in slots :
cpu 0 DIMM 1
cpu 1 DIMM 1
is it possible that my board support only one x5670!!!!!
and for dual use i must buy another cpu like x5570 ?!

this has been covered numerous times on this forum, please use the search feature to read the previous posts/answers in the future
the z600 rev 1 is not certified for the xeon 56xx line of cpu's you need a rev 2 board that has a updated intel chipset
it has been documented numerous times that rev 1 boards may or may not boot or reliably boot when using a 56xx xeon and trying to add a sec 56xx cpu to a rev 1 motherboard will usually not work
solution....................replace the rev one motherboard with the rev two board

Dear Professor: You stated that the Xeon Z600 will NOT support any 56XX ! Well sir, my Z600 came w/ TWO Xeon X5620's and 'she works just fine. Sooo, I simply want to UPGRADE in SPEED w/o busting my social INsecurity bank. Thanks for your time.

Donald81150,.......... you either did not read my post in full or you failed to understand what i posted
nowhere did i state that a z600 rev 1 motherboard would not run a xeon 56xx series cpu, i only stated it is a unapproved HP configuration that may or may not work with one cpu and more unlikely to work correctly with two cpu's
i suggest you go back and fully read my post on this subject

You may not know that there are two versions of the Z600..... an earlier one and a later one that I believe you have. Take a look at this post from the past, HERE .
It is easy to go into BIOS and confirm that your boot block date listed there is 1/7/10.... that confirms you have a version 2 workstation for your Z600. Let's assume you have a version 2 and would want to use the X5675 processor I describe in that post. Here is some up to date information: There was only one sSpec code release for that processor so use SLBYL to look them up on eBay. They each cost $1443.00 USD on release by Intel, have a max wattage draw of 95W, and are approved by HP for use in the version 2 Z600 either as a single or as a dual processor installation.
Current eBay cost is $30.00 each, shipping included. Your current heatsink/fan will be rated to 95W so you only need to buy some thermal paste and the two processors and you should be good to go. Passmark score for your dual E5620 processors is 8050. For dual X5675 it is 12447. So, $60.00 for the two processors and $7.90 for some Noctua NT-H1 thermal paste seems like quite a good investment. I'm still using mine upgraded that way..... plus a bunch of others.
