HP Z600 Workstation details, upgrades and benchmarks
                   HP Z600 Workstation    (WS)       
                   Why buy one and how to set it up.

P/N#:WD059av (top tag)

This WS is not some weak cheap PC, at all. 
It runs W10 64bit, OS, and has real ECC memory and up to 2 processors, E5620 ( Westmere-EP) quad core Xeon.  I think max Xeon CPU would be E5675 95watts limits this....
To run 2 processors you need both banks with matching ECC RAM.  DDR3-1333 (PC3-10,600)  in my case.  (4 cores each 8 threads each) With Quick path, (up to 25.6 GB/s between processors)
Why run ECC RAM?. The answer is simple, see this test done at Intel,  (hard cold proof of it working like magic)  The power of XEON's !
ECC ram has 9 chips not 8. (a huge clue  there) and Registered RAM allows the 24GB limit to go increase to 48GB total ram. (for those interested)
ECC is a low failure rate too, it has better testing done in production. (ECC is for Servers or  very high end Work stations, as this was)

The F10 BIOS info page shows processor stepping codes clear as day.(as does the CPU package top of the actual xeon CHIP) as does the intel processor scanner.

What are some of the cool things about this system.
One is the huge powerful mother board, even with open ended X8 slots ! (as seen below)

The Glue logic chip main, is  the the Intel ICH10  as is the X58  + ICH.  The X58 (IOH) has it's own tiny fan !  Note the QPI bus rates of 12.8GB/second, making Dual CPU's fly.


The PCI-e slots are version 2.0 compliant, not 3.
500 MB/s. per lane, so x16 is  8GB/s speed.  (version3, is  near2 times faster)  Gigabytes per second.   (version 3 mostly does not make the GPU go faster)
Even a new Nvidia (non LSI) TITAN card, will run full speed on v2.0 x16 PCI-3 express slots..  ( I have  spare GTX650 and will test it here later)_
SATA  3.0 Gb/s natively supported internally, fast enough for SSD if you like. (I have 120GB disk SSD)
Buy only C2 revision mobo with  this date 01/07/10" . Called the Boot block data;. B3 is the old version.  C2 can use registered DDM memory.
This WS is a tank,(at 33 to 43 pounds) and will never overheat.  (but if it did, no harm would happen , the BIOS speeds up fans  and slows down the clock rates or even halts both processors if need be.)
One advantage of a real workstation, is vastly better documentation, and longer support, mine is 8 years old and has full support. Manuals and drivers!
Be sure to flash the BIOS to 2018 , version. v3.61A or higher if found higher.  (BIOS F10 BIOS update works off one binary file and super easy to do! ) Never use WINDOWS to flash any PC.(use the BIOS engine)
Make no mistake, this is no HP Z6 G4 or Z8 system 2018. Intel® C622 chipset with up to 28 cores Z8 and DDR4 (for $10k bucks) 
The dual processor below is not slow, 8 cores total and 16 threads. E56xx Xeon's
This 2 processor upgrade cost me about $90
This workstation has great air flow baffles inside for CPU, memory  and many fans,  (2 in PSU, 5 inside case but is very quiet thinks to great firmware and the fan controller chip by SMSC not seen below.)



Block diagram 1: (real HP)  the GP Intel drawing is here.
Note the 2 times PCI slot power spec !  .. 
The  IOH is the Intel X58 chip IO-HUB circa 2008 (
The X58 has 36 PCIe lanes that are arranged in two ×16 links) (click to zoom drawing)

As you can see the X8 slots are wired X4 and are open ended.




CTO this box is Configured to Order:
No USB 3 here, but can be added super cheap to the PCI-e slot x8. (NewEgg sells them or near nothing)
Many of these have nice video card up grade, HP solid it with like 16 GPU card choices. Like the: NVIDIA Quadro 5000 2.5GB Graphics Card (I run a GTX650-Ti) (useless for gaming)
This WS were sold with up to 48GB of DDR RAM.  (6x8)
If the WS has a used HDD, make sure no kiddy porn there, best is do a DOD erase on the sucker.
Then load W10 fresh, in all cases do not leave other persons data on your just bought used PC. (DBAN the drive get the program here)

When you  buy any PC or workstation, be sure to reset the BIOS, hit the BIOS hot key prompted, at power on and then set BIOS to factory defaults. (day 1 , box opened)

This avoids Windows 10-64bit  going berserk with SATA PORTS SET in LEGACY mode, or worse "PIO",  set it to full DMA SATa ACHI mode.  Avoid SATA Native mode (IDE only).
Berserk as if W10 is running on  a floppy disk !
In BIOS turn off PXE boot features, fully. (or it will never boot to hdd )
In all cases I read each page of the BIOS and what is there, and not there and what I want and do not want.  (I want the PC to boot to HDD/SSD  and the SATA setup to max full featured(non legacy)
If UEFI or Safe boot is seen there, (can happen with BIOS upgrades) I shut them all off and the TMP chip OFF (not on this mobo).  (not only are  those a pain but tend to be buggy when 10 years old)
Make sure all fans work. (and the variable speed features)
Make sure all temperatures read ok,  below 50C in most cases is good. Less is better. (google Realtemp, download and run it , GT mode) Min runs near 34C

Load Windows  10-64bit last, when all above looks ok fresh install W10 now.
If you have  a SSD drive installed the OS  will scream. (acts snappy too) as I do.

That was  it for Day 1 checks.

I will next report all chips , that may !  fail freshly loaded  W10-64  (32bits PC's are now history/legacy/obsolete )
The results are that W10-64bit loads with no errors, and no drivers missing at all. (installed with 1gigalan cable plugged in and working)
The video card  works out of the box experience,  W10,  Mine is  ASUS Geforce 210 (GT218) in the X16 slot top. (business grade)  The MS update happened and the screen resolution what to 1600x900. Not soo shabby.
What matters most are sound and the NIC chip (Broadcom 5764) and Realtec. (realtek is correct spelling  ALC262)   All things inside hit the deck running.
My inspected,  chip list is here, in text form.

The ICH10R is fully supported . (R= raid option)
Integrated Intel/Realtek HD ALC262 Audio is on board.  (try the HP W8-64 driver in compatiblity mode if need be... or from Realtek actual or at MS) (or here)
Creative X-Fi Titanium PCIe Audio Card (slot CTO) options. (I don't have this)

The PCI-Z  report in text and csv(excel) are here.
That is it on Z600. (enjoy)


Bugs:?  The BIOS patch gets them all...and the world wide panic attach, called Meltdown ,etc.
Chip bugs? none
This PC(WS) has no buggy H67 intel chip DEV=1C02 ver 4 chips (SATA) . (port 2 to 5 bad bug can overheat and fail)

UPGADING TO a 2nd CPU: (done twice , 5620s then 5672)
The 2 processors both must be marked as E56xx (or as yours shows!)  and must have same Cache sizes internal., same speed clock, and same stepping code B1 in this case. The SLBv4 is what matters for matched.

I think 99% of all E5620s made are like this S-spec code (SLVv4)


Quote the service manual:
"Support for Xeon 5600 Series processors requires the C2 revision of the Intel 5520 chipset. Two methods
are available to determine if a specific Z600 system has the C2 revision of the chipset. 1.
Use the BIOS F10 setup menu to access the "Boot Block Date" from the "System Information Menu"  The mobo P/n also shows C2.
sSpec number must match, in this case SLBv4  ( the stepping can change and not the sSpec, or can change) but only you care about sSpec.

To add the 2nd processor, you need same ram added to CPU2 bank and a matching version of CPU by stepping version, speed etc.
"The second processor must be the same speed, cache, size, and type as the primary processor" (and maybe same stepping revision)
The memory must match side to side, like mine,  4G,2G,2G >>>>4G,2G,2G, same 240  pin sticks , unregistered (aka: unbuffered) ECC memory , (it will run as the slowest stick is)
Or buy 6x 4gb kits , registered   ECC. (all same type)
The Processsor is like $5 used, or $7 a pair on fleabay  and memory way more, at near (used)  $42 for memory for me, and $24 for CPU fan adds up $87 to upgrade , for the cost of adding the 2nd processor.
Here is the output of Intels own processor ID program.   Matching the top left data below, is what matters. CPU  TYPE down.  Mine below is: SLBV4 (B1)  I am told this code must match. (both mine match below)
This program is at Intel.com

CPU:
Do not attempt to mix processors as see below.    EBAY has vast amounts of these now, less than a pack of CIG's due to vast numbers of scrapped commercial servers (like Proliants 8 years old)





C2 is mine.
C2 tag looks like this on my MOBO, this is  the good newer version.

Below are some bench mark tests.   (1 and 2 processors, on line averages and my systems 5 column.)
Using  free  PASSMARK v9. (and CPU mark)  a $29 license I have,  CPU mark is my goal here, not graphics / disk/ or memory speed or size.. 
DB means data base averages of vast owners of this CPU.

Fastest Dual CPU is 39,000 rated, $10,000 each cost  the blazing fast  [Dual CPU] Intel Xeon Platinum 8168 @ 2.70GHz
The RANK above holds no importance to me, after all it changes by total system configuration and would be only good comparing 1 total system to another, what matters is the function Performance.
The newer version 9 Passmark program is a very fancy tool.

What is good with Passmark is this !
"Flexible no nonsense licensing. Once purchased you can move the software between machines as required. There is no hardware locking, no online activation process, no time based expiry & no annual fees. The software can be run direct from a USB drive or CD drive, and a network connection is not required to use the software. Multi user and site licenses are also available. See the FAQ to work out how many licenses are required in various scenarios."

My Z600 below (1 CPU here)
 ({ the Z8 with
[Dual CPU] Intel Xeon Platinum 8180 @ 2.50GHz  at $20000 for 2, SkyLake processors ($10k each CPU) ,  would do 31092 score, 6 times faster at 200+ times the cost of Z600  } (I think the full blown Z8 are $25,000 per PC) or more CTO.


My Game box  with GTX1050 , and AMD FX4250 does this.

2 CPU Z600 next, then 2 CPU with E5620 pairs.
Done...

next is
2 CPU Z600 next, then 2 CPU with E5672 pairs, the fastest CPU set that runs here, and not violate the 95watt limit. (each)  Chip version SLBYK(matched codes)
(pending ,,,, BINGO.   Pretty fast or and old Z600  82% percentile,too.





My DL380 G7 server is next. (as  point of reference only) below:




I was not happy with my new SSD speeds, and could not get max speed out of the stock SATA ports (1/2 of expected), (any ports) and I expect the mobo BIOS is weak on AHCI MODE?
I then inserted my SAS9211 RAID card (flashed to "IT" mode HBA) and connected it to the SSD,  and it screams fast   525/550 MB/s  (write read seq) sure the Raid card slows the boot time a tiny bit, but I could care less there.
 I added a 30mm  fan to the 9211 heatsink, the heat sink runs amazingly cool ! now.
The Dell H200 card ($30 used one of the cheapest made and fast) can be flashed to HBA firmware (seen  here) using the SFF-8087  cable adaptor
Kingston SSD model...SA400S37-120G(via RAID 9211,card, flashed to HBA mode."IT")
