Hi! I'm new here but done a bit of research already... And couldn't find an answer to that real question (found similar ones but not same). I have (because of warranty) 2 kits of RAM (same manufacturer, same model, same frequency) : 4x8GB 2x16GB My motherboard (Asus Prime Deluxe X299) has 8 slots and CPU supports 4 channels... What is the best way to install them as to preserve multi channel... And overall performance? Thanks in advance! Feel free to ask if info is missing

Hi all! I'm about install a new server and can't pick what would be better for SMB, 1x 10Gb or 4x 1Gb using SMB Multichannel. All the computers will be connected via 1Gb/s ethernet to a switch and the server to the switch. That's about it! Thanks

So i am looking for some 2.1 Speakers for around 100-150 €. What i really need is that they have a Multi Channel Input , so i can connect my PC and TV. And they should have a Bluetooth connection. The only one i found are the Z623, but i dont like the Satellites. Does somebody have some recommendation?

I'm have this multichannel usb sound card which is better than my on board sound card on my pc and on my android. When I plugged it on my phone, SPDIF out light is on but line out does not produce audio I use OPPO F5 Youth which supports OTG even in audio but it is only activated on SPDIF, how can I reroute or change my audio device to the 3.5mm Audio Note: I tried plugin my headphones from all the ports except SPDIF since I do not have one but the light in SPDIF is turned on

Hello forum. In short I want to achieve 2gbit transfer speed between my uRaid server and my Windows 10 workstation. I have my Windows 10 workstation with specs: Intel i7-6700k Asus Maximus Hero VIII 2x8GB Ram 1x Samsung 850 evo 1x 2TB Seagate sv35 Lan1: Integrated intel 219-v 1gbit Lan2: Realtek USB GBE 1gbit And my unRaid NAS with the following specs Intel i3-4160 Asrock B85 Pro3 2x4Gb ram 1x 2TB Seagate sv35 and other HDDs Lan1: Integrated Realtek 1gbit Lan2: PCI-E Realtek 1gbit I have my switch d-link DGS-1100-08 and router TP-Link Archer C7 I have researching these week a lot regarding this topic and the final answer tend to No. But i will show the options I find Link aggregation, NIC bounding and samba multi channel. I tried multiple combination of OS and methods. On the unRaid I setup bounding and set it to balance-rr - the only mode that can split a tcp connection. Between 2 unraid boxed and switch setup to link aggregation I achieved ~200MB/s (NICs in any combination) Transferring from unraid Box to Windows Server 2016 with balance-rr oin unraid and static teaming on windows i achieve ~200MB/s dl and ~100MB/s upl . Don't know why but it seems windows doesn't split traffic but i saw in the switch the traffic goes on both NIC to unraid. Windows 10 doesn't support NIC Bounding . I see NIC bounding doesn't work windows 10 - linux . The only Requirement is that my workstation to be Windows 10. The Server can run on windows or unraid. I tested samba multi channel and between Windows 10 - Windows Server 2016 I got the multi channel to work out of the box almost( worked only when pairing intel NIC with the USB NIC and on other pc the two realtek, swaping the usb with the PCI-E card didn't work with multi channel). Achived ~200MB/s. That is fine with me but WIndows server works very slow and i see decreased in speed and lag when using it. I tested unraid with all its features and it is what i want due the multiple options, easy samba share, docker, wm and many useful plugins and also very good performance. I rather prefer Unraid The main problem I can't get samba multi channel to work. I enabled it in config and checked if the version of unraid haves samba version that haves multi channel. Swapped the NICs and still doesn't work. Can someone suggest what i need to tweak or what can be the problem?. unRAIDServer-6.3.5 having samba: 4.5.10 (CVE-2017-7494) Settings added in samba: server multi channel support = yes aio read size = 1 aio write size = 1

This guide has been written by someone who is NOT a certified expert. If any information is inaccurate or could be phrased better do contact me so I can update it. A step by step guide to setting up SMB3.0 Multichannel on FreeNAS. What is Multichannel? Multichannel, which is a feature of SMB3.0 (a Microsoft file sharing protocol) enables people to simply and easily aggregate multiple physical network links and allows a single client to utilize the combined bandwidth. For example, instead of being stuck with 1Gbit file transfers you could have 2Gbit or 4Gbit. In theory if you're using 10Gbit you could aggregate them to create 20Gbit or 40Gbit to a single client. As of Windows 8 and later SMB3.0 Multichannel is included and enabled by default. At the same time Microsoft has refined the drivers for this process to a point where setting it up is plug'n'play in most instances. Now SMB3.0 multichannel on FreeNAS or any other *NIX based system on the other hand isn't as easy. Not only are there prerequisites but your configuration has to follow specific instructions. SAMBA is responsible for bringing SMB support to *NIX not Microsoft so enabling certain features of the protocol are done differently. This guide will help people who want to set this up on FreeNAS but may prove to be useful for people using other versions of *NIX. It should also be known that Multichannel as of late 2017 is still considered experimental and you mileage may vary. SAMBA has no official support for it but it can work with the right setup. What are the prerequisites? In order to use multichannel at all on FreeNAS you need to have SAMBA version 4.4.0 or later. You can check what version you have by entering shell and using the following command: samba --version If your version is outdated one method of obtaining an up to date version is to update FreeNAS itself. What hardware is needed? There's a few options. You can use a single multiport NIC that has 2 or 4 ports or you can use multiple NICs which will offer redundancy as SMB multichannel if the aggregated link is lost the remaining link(s) will continue to operate at the cost of reduced performance. Each machine will require an equal number of ports. IMPORTANT: It is very recommended when aggregating the links that the NICs support Receive Side Scaling (RSS). RSS allows the responsibility of handling multiple TCP/IP connections to be divided up across multiple CPU cores. If you just so happen to have NICs that support Remote Direct Memory Access (RDMA) this will also work but this is a feature on enterprise NICs and is only really applicable to very low latency applications. The best way to check if your NICs support RSS is to find what chipset is used and search that chipset on the web. For example the Intel i210, Intel 82574L, & Broadcom BCM57810S all support RSS. You will also require a network switch. Any layer 2 switch should suffice so long as it has a sufficient number of ports and the ports support speeds equal to that of the NICs. How to configure: This is where things differ quite a bit from Microsoft Windows implementation. Note that the interface configuration on your Windows machine will need to follow the same structure as on the FreeNAS server. The way Microsoft setup the protocol to work was in 2 different ways. The user could plug every port into the switch, have a router connected running DHCP, have every port on the NICs set to DHCP, then SMB would automatically see every port on the same network and aggregate them. IMPORTANT: The other way SMB3.0 multichannel can work is by setting up the interfaces in pairs on different networks/subnets. At this time this is the only method SAMBA supports for multichannel. Below are a few ways of achieving this: If the server is part of your local network and you want 2Gbit or 4Gbit but everyone else is fine with 1Gbit then that means the existing network needs to stay in place. So lets say the existing network is 192.168.0.0 255.255.255.0 and the server has a static address of 192.168.0.254 you can set up the other interfaces on the server on the 192.168.1.0 network then 192.168.2.0 and 3.0. Now admittedly this is a huge waste of addresses if the aggregated connection is only for one host. The following is a more proper configuration in this instance: PC NIC1: 192.168.0.10/24 (/24 = 255.255.255.0) PC NIC2: 192.168.1.1/30 (/30 = 255.255.255.252) FreeNAS NIC1: 192.168.0.254/24 FreeNAS NIC2: 192.168.1.2/30 A /30 subnet is very useful for point to point connections. This prevents wasting addresses. If you have 4 interfaces on the server and you're the only person who needs 4Gbit probably the best way to set up the addresses without modifying the existing local network would be to go: PC NIC1: 192.168.0.10/24 PC NIC2: 192.168.1.1/30 PC NIC3: 192.168.1.5/30 PC NIC4: 192.168.1.9/30 FreeNAS NIC1: 192.168.0.254/24 FreeNAS NIC2: 192.168.1.2/30 FreeNAS NIC3: 192.168.1.6/30 FreeNAS NIC4: 192.168.1.10/30 In this configuration (above) each pair of interfaces (.10 & .254, 1.1 & 1.2, 1.5 & 1.6, 1.9 & 1.10) are all on different networks or more accurately would be to say each pair are on different subnets. The subnet mask (the /24 & /30 also depicted as 255.255.255.0 & 255.255.255.252) determines what addresses or octets are network bits and which are host bits. What if I want an independent dedicated 2Gbit or 4Gbit network with 1 host? If you buy or have a pair of dual/quad port 1Gbit NICs and have a switch you want to dedicate to linking the server to your computer with then it makes things easier. First off you'll have to setup the interfaces on networks other than your home/office network. Personally if the primary network is 192.168.0.0 or 172.16.0.0 or 10.>0.0.0 then the easiest way for me to subnet the interfaces would just be to use Class A: 10.0.0.1-.2/30 10.0.0.5-.6/30 10.0.0.9-.10/30 10.0.0.13-.14/30 What other configuring is necessary? A big thing that differs from Windows is that SAMBA has multichannel disabled by default. You have to enable it. You can do this by going to the FreeNAS WebUI then going to Services and configuring the service CIFS/SMB (its name will be either CIFS or SMB depending on your version) you will then have to find the Auxiliary Parameters option (to see it you may have to click Advanced Mode). In here you will have to type the following command: server multi channel support = yes This will modify the smb.conf file. You will also have to set the Server maximum protocol to SMB3.0_11. There's also _02 & _00 these correspond to which version of windows you're using but setting the maximum protocol to _11 will make the connection between Windows and the server use the highest protocol that they both support. Troubleshooting: With everything setup in this manor you should now see speeds in excess of 1Gbit for file transfers. If not re-check your configuration. If this doesn't fix the issue try using SMB3.0_02, SMB3.0_00, or SMB3.0. If none of this helps it is sometime necessary to update windows for multichannel support.

Hello I'm having a little trouble with my transfer speed to and from my storage "server". Gaming rig: Intel i5-4690k 16GB RAM Samsung 840 Evo 500GB 1 Intel nic 1 Realtek USB3 nic Latest W10 Server: Asrock C2750D4I Intel avaton C2750 32GB RAM Samsung 840 evo 250GB system driver 8x2TB HDD with parity through Storage spaces 2 intel nic The speed is great in the beginning with over 200MB/s, but halfway it drop to about 30MB/s. If I pause the copying it pick up speed a little, then drops down again. Have tested with a lot of setting but no difference. Any suggestion? Best regards, Henning

Hi, Just finished my new media server built, however I came across a strange situation the SMB Multichannel file transfer only work it one way. Here is the situation: Gaming Rig (A): Intel Core i7-4770k at 4200Mhz Kingston HyperX 16GB at 2400Mhz Asus Z87-A Plextor 128GB 128M5S Seagate Desktop HDD 2TB ST2000DM001 Sapphire Tri-X OC UEFI 290X Intel i350-T4 AM4 Quad Ports (Fake intel nic) Win 10 Pro ver 1511 build 10586.164 Media Server (B): Intel Core i3-6100 at stock speed Kingston Hyper Fury 1866Mhz 16GB Asus H170M-E-D3 Plextor 256GB PX-256M6G-2260 M.2 LSI MegaRaid 9261-8i 8 x Seagate ST4000VX000 at Raid50 Intel i350-T4 AM4 Quad Ports (Fake intel nic) Win 10 Pro ver 1511 build 10586.164 Both Rig are connected to D-Link 1024D Unmanage 24 Ports Switch The scenario is I can copy to and from (using rig B) to A with SMB Multichannel triggered 8 of the ports and the load evenly distrubuted, but if copy to and from (using rig A) A to B only 1 port is using and no the SMB Multichannel are not triggered, I have made sure the multichannel server and client are both enabled using PowerShell and the RSS are properly configured, so could anyone shed some light of what really going on here? According to Linus video he said SMB require powerful CPU to fully utilize the SMB Multichannel, but on my case I am able to trigger the SMB on less powerful machine tho. If the CPU really the cause does i5 enough for the SMB? Thanks!

<rant> I got a great deal on the Tiamat 7.1 and decided to buy it. It was the worst mistake of my life, well apparently. It's a good idea and all but the audio quality is just so pathetic! Here are my 1. Comfort - It isn't as comfortable as I'd like it to be but that's just me and I'm comparing it to my old trusty HD518. 2. Ear fatigue - I can't keep them on for long hours in the day. I understand that comparing this with my Sennheiser HD518 is unfair but I have worn those for 10 hours straight without any fatigue whatsoever! With the Tiamat, 30 mins and it feels like my ears can just start bleeding any moment. 3. Audio quality - It's truly, amazingly and spectacularly terrible. The worst sound that I have ever heard in a headphone by far! 4. Build quality - Apart from the headband, this appears as if it was built by some crappy Chinese OEM which makes low cost products. And this isn't a cheap headset. 5. Cable quality - Perhaps the only positive thing I can say about this headset. The cables are well braided and very sturdy. What I don't get is, how can reviewers lie so much about the sound quality of this crappy headset. Am I doing something wrong here? I was using it with an M-Audio Revolution 7.1 and then an ASUS Xonar (7.1), which I bought solely for this trash (what a waste of my hard earned money!) and it was just plain bad. **** you Razer! Seriously, I'm never buying an audio product made by you again. Why are people buying this crap? It's bad with games and movies. I have boxed it back and it lies now at the back of my storage. If anyone in India is interested in buying this garbage, I'd be happy to sell it to you. But my advice is, DON'T. This is a bad product and should not be used by anyone, ever! </rant>
