Actually they accepted it back for a penalty of 15%. That's still reasonable :)

Well those are the only DDR4 based systems I have and there it doesn't work. Approx 100 EUR.

Yep. Unfortunately I think I missed the 14-day return deadline on 1 DIMM stick out of 8. Not sure if they could still honor it with a reduced refund or it I have to try to sell it on eBay :(.

Just tried with Kingston KSM26ED8/16HD. Very short test so far, but all memory detected and not getting random reboots yet. IPMI/BMC event log is also empty (not getting Uncorrectable ECC Errors in System Event Log). Seems like the DIMM RANK matters after all :(. Too bad because the Crucial was...

I think we are not talking about the same thing. For me "A" is one channel and "B" is another channel. They are controlled by independent memory controllers. In order to have a "dual channel" RAM you need to populate both B2 and A2, we agree on that. What I meant is that when mixing memory...

Weird, I had the feeling it was channel A/B/C/D (at least on dual socket motherboards), and "1" and "2" were the number of the DIMM within that channel. Are you sure the "logic" is reversed on single socket boards ? No standard regulating interoperability? Damn it ... Here in Europe you get...

It's the same CPU model, but a different one. Same with the MB: same MB model, but a different one.

It was the same P/N as before, that was the Batch number (just to say it's again different batches, even though I ordered at the same time from the same retailer). I installed A1 and A2 (channel A) with one batch number, installed B1 and B2 (channel B) with the other batch number. The channels...

Short update. Just tried a different set of MC+CPU+PSU and 4x new&different sticks of RAM (2 sticks DPASAYN001 - 2146 / 2 sticks HM00004A33 / 2141). Same instability and lots of Uncorrectable ECC errors reported by BMC/IPMI. Debian Linux crashes/panic & reboot approx 30 seconds after login...

Just got a Antec Signature Platinum 1300, since it was about the same price as the Antec Signature Platinum 1000 (for the Desktop) :).

I don't believe I can tweak the voltage. Most I think I can do is tweak the power limit for Intel Turbo Boost. It's not a board intended for overclockers ;). I cleared IPMI logs before any new "attempt", and yet it got full 5 min after starting Memtest86 again (although nothing was reported in...

I don't think I did. Might as well try. I'm just a bit unmotivated to remove the cooler every single time :(.

I am tempted to also upgrade my Desktop, that way I can test these RAM DIMMs to see if they are the faulty ones. Some new NVIDIA GPUs (RTX3000) apparently had issues with Seasonic, although I am stuck on GTX 1000 for now ;). Would you say the Antec Signature Platinum 1000 compare well with...

Could be a case where 4x half bad sticks allow the MB to boot, but as soon as something "real" gets done, it just crashes :confused:. I agree with Intel TDP ratings being very off. AMD usually is/was more realistic on those. About the PSU rating, I'd tend to agree that it's not hugely...

First of all, thank you for your exhaustive and quick reply, GiGaBiTe ;). I'll have to dig this up ... I assume previous boot I can find out with "journalctl -k -b -1" (-1 argument for previous boot) Ah, alright, thanks for the explanation :). Sorry, my bad, probably I didn't express myself...

I just built a new server out of second hand components (minus the RAM which is new). - Motherboard: Supermicro X11SSL-F (updated to BIOS 2.6) - CPU: Intel Xeon E3 1240 V5 - RAM: 4 x Crucial MTA9ASF2G72AZ-3G2B1 (DDR4-3200 ECC UDIMM 1Rx8 CL22) - PSU: Seasonic G-360 - Cooler: Noctua NH-L12S All...

Thank you for your answer. The Windows 10 sits on top on a NVME drive. Right now it's a striped pool (RAID0, no redundancy at all) so I'll have to move it / destroy existing pool / recreate it using mirror VDEV. Right now that project has been put a bit on the side. In order to have...

I quickly checked them but they seem to provide only outbound SMTP. I would really like to have also POP/IMAP. Like from my LAN, send an email through the SMTP relay server and store it on the server where it can be accessed. That way I will be able to read notifications all the time (webmail...

I used to use Google SMTP server for sending cron notifications in case of faults (e.g. mdadm array broken, smartctl errors, now ZFS, etc) but I am seeing that it's getting more and more unreliable. In the paste i used msmtp to interface directly with the google server wih a gmail account. Now...

Dear all, I know it might be a strange request but please bear with me ... I started using VMWARE ESXi about 5 years ago as my virtualization platform of choice in my home lab. Since then, due to easier backup, scripting and base OS (Debian), I switched to Proxmox VE (without subscription). All...

Thank you for your replies as usual, _gea. Is there a "zfs set" command to force sync at all times? I'm not so much concerned about performance as I am about consistency. I doubt a SLOG is required if the primary storage is NVME anyway. In Proxmox I disabled Caching options for each virtual...

I would be interested in your opinion because I am migrating all my machines to Virtualized solutions (mostly Proxmox VE, still have one ESXi Box). For the Host (or AIO using OmniOS + Napp-IT) filesystem I'm without doubt using ZFS. Does it matter the FS that the Guest will be using? Of it...

I have a crazy request. I have a X9Dri-LN4f+ Motherboard and PCIe bifurcation seems to work just fine (tested with an ASUS Hyper M.2 adapter). My problem is that the GPUs take 2 slots each and then I'm left without any room for other devices. So I'd like to cable using some riser extensions to...

I found a solution that works for me (Supermicro X10SLL-F, Xeon E3-1270v3 CPU) that I just bought second-hand and came with this CPU backplate (BKT-0028L) installed as well as a Passive Dynatron heatsink. Here is my solution to install a more efficient (and less noisy) cooler on a Motherboard...

Sorry for not replying sooner, I didn't get any new notification :(. Unfortunately that's not the case. I'm renting an apartment and no individual garage. Plus I wouldn't put my server in the laundry room because of humidity. However I noticed that since I moved in this apartment, the walls...

As a side note I should add that these servers will basically be only turned on when needed. Essentially all they will be doing is compiling (DistCC or Icecream clusters). They generate far too much heat to be able to use them all day long. Also the electricity bill suffers :( So I would...

Sorry for not saying before. I live in Switzerland. I can also order things in Germany though (ship them to a friend :)). Oh my god :eek:. So expensive. That's almost 700$ :confused:. And I'm fairly sure here in Switzerland but also probably in Germany it's going to be more expensive than in...

I'm not sure i understand your point about the electrical conductivity. From what I know the heatspreader of the CPU is supposed to be grounded. I assume so since the coolers I know touch the case chassis, and since this is earthed, it wouldn't be a very good idea that the spreader is at...

Yes references to specific products would be great, thanks ;) So every say 6 months you need to change your coolant :confused: ?

Can you provide some more specific references please? I'm a bit against putting both servers on the same cooling circuit because then the electrical wiring will probably get more complicated, right ? Also thermally the last CPU will have much higher water temperature. Series connection of...

Would you have a water cooling configuration in mind ? There don't seem to be many 2011 Narrow/Square ILM water coolers. I think there are adapters for the Corsair H series on eBay but I'm not sure. The problem would be how to get the "pipe" out since it's a closed loop I need to put the whole...

As the title says I did the (probably big) mistake of buying 2 x Supermicro SC825 TQ-R740LPB 2U chassis. One at the moment is equipped with a X9DR3-F (one socket not working, I will probably need to check for bent pins) and the other with a X9DR3-LN4F+ (both sockets working). Both boards are...

I had the impressions until now that in all your tutorials you reccomended PCIe passthrough as the only solution reliable for ZFS. Raw disk mappings were highly discouraged since they could lead to all sort of problems (data corruption, access timing issues, ...). What changed ?

When you say "can block a NIC" I assume you mean by its MAC address, right? That's not considered very safe on a (W)LAN as anybody can easily spoof and fake its MAC address. It provides an additionnal layer of protection, sure, but not a very tough one. Isn't NFS via ssh private key possible...

How would be a firewall any different ? You would still apply rules based on IP and ports, right ? I could also implement 802.11 x authentication but that poses the problem with the few unsupported devices. Then I need a separate (V)LAN, firewall rules, ... I guess it gets complicated really...

Thank you for your reply _Gea. Would you mind explaining this is more details please ? In your napp-it all-in-one tutorials you purposedly suggest using OmniOS+Napp-it to host esxi virtual machines using NFS. I agree that there is no SMB support in ESXi, but is this unsafe then? What would be...

Hello, I hope I can get some help with napp-it since I really like it. For samba setup it works flawlessly. However for NFS setup I'm starting to lose my hair for NFS. Normally on GNU/Linux (or FreeBSD) you setup a new group (adduser/useradd with its GUI) and a new user (with its UID) on the...

Not sure if I should post here but with the latest AIO appliance (napp-it_15d_ova_for_ESXi_5.5u2-6.0. (Sep 18,2015)) I manage to get my IBM M1015 detected. However no disks were detected (tried Disks -> initialise and parted -l but to no avail). Controller was cross-flashed to LSI 9211-8i IT...

Bump. Anybody has any ideas on which adapters to pair with this switch ? I don't think the Mellanox I own are compatible ...

I just purchased a Voltaire InfiniBand 4036 Infiniband swich for what I consider a steal for that kind of hardware (400$ but with shipping&duties it became 480€). As far sa I understand I now need some Mellanox Connectx-2 VPI cards for use with this switch, right? The Mellanox Connectx-2...
