Z400 with Non-ECC memory?

[Dan_WGBU]

Tiebreaker, as you found out, systems might work with non-ECC memory.  Mixing ECC and non-ECC will probably cause all the memory to work in an non-ECC mode.  

ECC memory is nice since it automatically corrects single bit errors, and prevents system crashes. 

If you're curious how well the Z400 is working with non-ECC memory, you could see if there are any hardware errors in the Windows logs.  

   - Launch Computer Management (one way to launch is to right click on "My Computer" and click Manage).  

   - Then go to Event Viewer -> Windows Logs -> System

   - Under Actions in the right-hand column, clik on "Filter Current log..."

   - In the Filter Current Log popup window, select Critical, Warning, Verbose, and Error in the Event Level selections, and click OK.

You may see a lot of items.  Click on the Source header to group the same items together.  If there are some WHEA errors, they could be caused by memory errors, either corrected or uncorrected.  Look at the description of each error. 

Let me know if you see these WHEA errors, I am curious what you find.  If there are none, great.

I have Z800 with 48 GB of non ECC ram and the system does not show any WHEA errors under Windows Server 2012 R2.  I am running 3D and VFX and Editing software without problems.

The Advisor shows this for ram:

Size:     4 GB
Memory Type:     DDR3
Rated Speed:     1333MHz
Error Correcting (ECC):     No
Device Locator:     CPU0 DIMM1
Bank Locator:     
Manufacturer:     JEDEC ID:01 98
Serial Number:     1A571652
Asset Tag:     
Part Number:     9905471-009.A00LF
Total width:     64 bits
Data Width:     64 bits
Form Factor:     DIMM
Device Set:     not part of a set
Type Detail:     •    Synchronous
•    Unregistered (Unbuffered)
Number of ranks:     2

I am wondering how can I find out who is the  Manufacturer:     JEDEC ID:01 98    by JEDEC standard number.  I know there is a PDF for download but for $500 with all manufacturers listed. 

I would like to go to 192 GB of ram for After Effects and was wondering if I can use the same ram in 16 GB sticks if they exist but non ECC.

I confirm that non ECC works with my Z800 workstation without single memory error.  I am running the last revision board from HP for z800 and the last BIOS.  I remember long time ago reading about non ECC support for this revision and BIOS but I can't find that info anymore.

Cheers,

FILMTOOLS, the 98 might mean Kingston memory as the manufacturer of the DIMM.  I am not positive about that, though.

You did not say if you were going to try 16GB unbuffered or registered memory. 

Registered (buffered) memory is recommended on the Z800 because it puts fewer loads on each memory channel.  For example, 16GB sticks might have 2 or 4 ranks of DIMMs on them, so each memory socket will have 2 to 4 loads, or 4 to 8 loads per each channel (a channel is a pair of black and white connectors).  High loads reduce signal integrity, and makes errors more likely.  Registered memory puts one load per socket, to reduce the load.

I was looking at ECC memory but it is expensive I was hoping to find non ECC ram that I am using now but in 16 GB config so I can go up to 192 GB and see how it works.  Right now in After Effects when I have large comps I can easy reach 48 GB that I am using now and then it is cached to disk.  I would like to have a lot more ram for previews.  So far I have not seen any mem. errors in windows log.  Does that mean that ECC is a lot faster compared to non ECC ram? 

And do we have any info that it will work with non ECC past 48 GB that I have now?

thanks,

Edin

Can confirm, HP Z400 board working with non-ECC ram:
4-pin PWM CPU cooler
4x4GB of RAM, 2x4GB G.Skill Ripjaws X DDR3-1866 non-ECC low density (double sided, 2 rank), 2x4GB Kingston KVR13N9S8/4 non-ECC high density (single sided, 1 rank). Total 16GB RAM
80GB SATA1 mechanical hard drive w/ Windows 10 Pro
512MB GeForce 8800GT
500W EVGA Power supply

Have not tried mixing non/ECC DIMMs, but all RAM only requires 1.5v so higher voltage RAM not tested (wouldn't recommend it either).

I'll be testing later: high power GPU's, SLI (afaik SLI is supported anyway)
off-the-shelf SATA 3 SSD (Samsung EVO 850 120GB) [I read these may have issues, will report]

Not bad for a system that cost me $70 + parts I had lying around from incompatibilities and upgrades.

--ISSUES--
Only thing I'm having trouble with is I cannot for the life of me get it to connect to my network via onboard Broadcom Extreme ethernet.
The router (ASUS RT-N66U) sees it and assigns it an IP address, but it only runs at 10Mbps speed, and Windows 10 displays "unidentified network", status page of the adapter displays no IP address, even attempting to assign a static IP doesn't work.

Assistance?

Hello,

Has anyone tried non ecc memory on z640 ?

Thanks

[jvpprov2416]

Yeah well listening to all you guys I bought some non-ecc and it does not work. System does not boot. Power button turns red instead of blue. I have version 2 with 6 memory slots and the latest bios update.

hynix 4GB 1Rx4 PC3L-10600R -9-10-C1...... I tried 6 of these, then tested them all one by one...non of them work in the machine.....

[mew905]

10600R indicates it's a Registered DIMM.... these dont work in anything but server hardware and high end workstations (such as the Z800 mentioned above) 😞 You need unregistered DIMMs, the Z400 isn't compatible with Registered DIMMs, (typically denoted by a "10600U") Sorry man. I didn't even know non-ECC RAM COULD come in Registered form.

Another thing: high density RAM doesn't work in these early intel boards. I cant remember how you can figure this out, but essentially if memory serves, a 4GB DDR3 DIMM needs to be double sided, with 8 chips per side (I MAY be thinking of the 8GB DIMMs though, you'll have to look into this). the cheaper RAM that you can find usually from G.Skill and other manufacturers that says "guaranteed compatibility" are usually low density DIMMs, as thats how they can guarantee compatibility with nearly every DDR3 capable board. AMD has never had this issue to my knowledge.

I didn't realize that either.....hehe

[jvpprov2416]

That meme is so much more...I was trying to find something cheaper.
