Z400 Workstation (6 Dimms)

[ravenly]

Hello HP Experts,

I need help with the following questions/doubts for my Z400 Workstation.

Q1 Does Z400 Workstation support or will work with a Non ECC Unbuffered RAM  as long as it is DDR3 1333 Mhz ?

-Base on the links below :

Page 8 and 9
Only unbuffered DDR3 DIMMs are supported
http://www.bargainhardware.co.uk/content/specifications/z400_datasheet.pdf

Page 2
http://file.e-disti.com/new_z400_datasheet.pdf

It only says ECC Unbuffered RAM is supported, but I want to get confirmation just incase we can use a non ECC RAM

I also found this in forums

z400 - 6 slot memory configut=ration

https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/z400-6-slot-memory...

Please confirm.

Q2 The Z400 Workstation I have is with  6-DIMM slots and Intel Xeon processor W3505, 2.53 GHz, 4 MB cache, 1066 MHz memory, 4.8GT/s QPI, Dual-Core:

-What is the maximum capacity per DIMM slot/Memory slot? I noticed on the documents I found below that the maximum per slot is 4GB? Please confirm if more than 4GB per stick is still supported ? Ex. 1 stick of 8GB

-Also I want to confirm the Memory Speed Supported are 800 MHz, 1066 MHz and 1333 MHz DDR3? how about more than 1333 MHz? example this 1 stick of 8GB DDR3-1600 is this supported in Z400 Workstation ?  

Some one is trying to sell me this "1 stick 8GB DDR3-1600 ECC Unbuffered DIMM CL11 2Rx8 1.5V Kingston F Die (Server Premier)   8GB 2Rx8 PC3-12800E-11-12-E3"  not sure if this is supported but he said that he got it from a Z400 worksation.

Q3 Is Nvidia Geforce gtx 550ti oc edition 1gb 192bit ddr5 compatible with Z400 Workstation ? I can't find compatible matrix or reference saying its compatible  please confirm.

Q4 Currently I have Intel Xeon Processor W3505 2.53 GHz, 4MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core and as per the document below are the available processor for Z400 Workstation:

Intel® Xeon® Processor W3503 2.40 GHz, 4MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
Intel Xeon Processor W3505 2.53 GHz, 4MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
Intel Xeon Processor W3520 2.66 GHz, 8MB cache, 1066 memory, 4.8 GT/s QPI, Quad-Core, HT, Turbo
Intel Xeon Processor W3550 3.06 GHz, 8MB cache, 1066 memory, 4.8 GT/s QPI, Quad-Core, HT, Turbo
Intel Xeon Processor W3565 3.20 GHz, 8MB cache, 1066 memory, 4.8 GT/s QPI, Quad-Core, HT, Turbo
Intel Xeon Processor W3670 3.20 GHz, 12MB cache, 1066 memory, 4.8 GT/s QPI, Six-Core, HT, Turbo
Intel Xeon Processor W3680 3.33 GHz, 12MB cache, 1333 memory, 6.4 GT/s QPI, Six-Core, HT, Turbo
Intel Xeon Processor W3690 3.46 GHz, 12MB cache, 1333 memory, 6.4 GT/s QPI, Six-Core, HT, Turbo


Is it okay if i'll purchase or just replace my processor with the latest/fastest processor for the HP Z400, Intel Xeon Processor W3690 3.46 GHz, 12MB cache, 1333 memory, 6.4 GT/s QPI, Six-Core, HT, Turbo? without changing motherboard ?


Please confirm thanks in advance.

Hi,

Review page 13. The documentation indicates ECC only dimms. Also, review page 5 to determine which processor supports your DDR3 1333 Mhz dimms.

Thanks for the answer.

But what can you say about this topic from forums :

z400 - 6 slot memory configut=ration

https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/z400-6-slot-memory...

Its seems that non ECC will work with  Z400..

Then regarding if my Nvidia Geforce gtx 550ti oc edition 1gb 192bit ddr5 is it compatible with Z400 Workstation ?

Thanks in Advance

Hello, I am in need of some help, I am a new user of the HP Z400, I recently acquired a memory of 8GB ECC each bank. But I'm discovering that it only supports 4gb. Is there any BIOS update that allows you to use 8gb dimm's? thank you very much.
I apologize for my English, which is very bad. I am from Argentina.

Did you try inserting the 8gb ecc ram to your Z400? did it work?

Hi, due to lack of time I still can not work on the z400, with the version of BIOS v.3.10 that it has currently not working, but I want to update to v3.61 to do the test again.

Hello. I run a Z400 workstation with 6 dimms. all running

Ram -  4gb 1rx8 pc3l - 12800u , so 24 Gb ram.

CPU - Intel Xeon E5649 six core CPU.

Video - GTX 760 4gb ddr5.

The Motherboard shows up as HP 0B4Ch D with x58 chipset.

BIOS: Hewlett-Packard 786G3 v03.61 03/05/2018
