When setting up an XPEnology system, you must first select a DSM platform and version. XPEnology supports a few specific DSM platforms that enable certain hardware and software features. All support a minimum of 4 CPU cores, 64GB of RAM, 10Gbe network cards and 12-disk arrays. When you choose a platform and the desired DSM software version, you must download the correct corresponding loader. That may not be the "newest" loader available. The last 6.x version (6.2.4-25556) is functional only with the TCRP loader. TCRP is very different than the Jun loader. If you want to learn more, or if you are interested in deploying the latest 7.x versions, see the 7.x Loaders and Platforms thread. Be advised that installing 6.2.4 with TCRP is basically the same procedure as installing 7.x. Each of these combinations can be run "baremetal" as a stand-alone operating system OR as a virtual machine within a hypervisor (VMWare ESXi is most popular and best documented, but other hypervisors can be used if desired). Review the table and decision tree below to help you navigate the options. 6.x Loaders and Platforms as of 16-May-2022 Options Ranked DSM Platform DSM Version Loader Boot Methods*** Hardware Transcode Support NVMe Cache Support RAIDF1 Support Oldest CPU Supported Max CPU Threads Notes 1,3a DS918+ 6.2.0 to 6.2.3-25426 Jun 1.04b UEFI, BIOS/CSM Yes Yes No Haswell ** 8 6.2.0, 6.2.3 ok, 6.2.1/6.2.2 not recommended for new installs* 2,3b DS3617xs 6.2.0 to 6.2.3-25426 Jun 1.03b BIOS/CSM only No No Yes any x86-64 16 6.2.0, 6.2.3 ok, 6.2.1/6.2.2 not recommended for new installs* DS3615xs 6.2.0 to 6.2.3-25426 Jun 1.03b BIOS/CSM only No No Yes any x86-64 8 6.2.0, 6.2.3 ok, 6.2.1/6.2.2 not recommended for new installs* DS918+ 6.2.4-25556 TCRP 0.4.6 UEFI, BIOS/CSM Yes Yes No Haswell ** 8 recommend 7.x instead DS3615xs 6.2.4-25556 TCRP 0.4.6 UEFI, BIOS/CSM No No Yes any x86-64 8 recommend 7.x instead DS916+ 6.0.3 to 6.1.7 Jun 1.02b UEFI, BIOS/CSM Yes No No Haswell ** 8 obsolete, use DS918+ instead DS3617xs 6.0.3 to 6.1.6 Jun 1.02b UEFI, BIOS/CSM No No Yes any x86-64 16 6.1.7 may kernel panic on ESXi 4 DS3615xs 6.0.3 to 6.1.7 Jun 1.02b UEFI, BIOS/CSM No No Yes any x86-64 8 best compatibility on 6.1.x * 6.2.1 and 6.2.2 have a unique kernel signature causing issues with most kernel driver modules, including those included in the loader. Hardware compatibility is limited. ** FMA3 instruction support required. All Haswell Core processors or later support it. Only a select few Pentium, and no Celeron CPUs do. ** Piledriver is believed to be the minimum AMD CPU architecture to support the DS916+ and DS918+ DSM platforms. *** If you need an MBR version of the boot loader because your system does not support a modern boot methodology, follow this procedure. CURRENT LOADER/PLATFORM RECOMMENDATIONS/SAMPLE DECISION POINTS: 1. DEFAULT install DS918+ 6.2.3 - also if hardware transcoding or NVMe cache support is desired, or if your system only support UEFI boot Prerequisite: Intel Haswell (aka 4th generation) or newer CPU architecture (or AMD equivalent) Configuration: baremetal loader 1.04b, DSM platform DS918+ version 6.2.3 Compatibility troubleshooting options: extra.lzma or ESXi 2. ALTERNATE install DS3617xs 6.2.3 - if RAIDF1, 16-thread or best SAS support is desired, or your CPU is too old for DS918+ Prerequisite: USB key boot mode must be set to BIOS/CSM/Legacy Boot Configuration: baremetal loader 1.03b, DSM platform DS3617xs version 6.2.3 Compatibility troubleshooting options: extra.lzma, DS3615xs platform, or ESXi 3. ESXi (or other hypervisor) virtual machine install - generally, if hardware is unsupported by DSM but works with a hypervisor Prerequisites: ESXi hardware compatibility, free or full ESXi 6.x or 7.x license Use case examples: virtualize unsupported NIC, virtualize SAS/NVMe disks and present as SATA, run other ESXi VM's instead of Synology VMM Option 3a: 1.04b loader, DSM platform DS918+ version 6.2.3 Option 3b: 1.03b loader, DSM platform DS3617xs version 6.2.3 (VM must be set to BIOS Firmware) Preferred configurations: passthrough SATA controller and disks, and/or configure RDM/RAW disks 4. FALLBACK install DS3615xs 6.1.7 - if you can't get anything else to work Prerequisite: none Configuration: baremetal loader 1.02b, DSM platform DS3615xs version 6.1.7 SPECIAL NOTE for Intel 8th generation+ (Coffee Lake, Comet Lake, Ice Lake, etc.) motherboards with embedded Intel network controllers: Each time Intel releases a new chipset, it updates the PCI id for the embedded NIC. This means there is a driver update required to support it, which may or may not be available with an extra.lzma update. Alternatively, disable the onboard NIC and install a compatible PCIe NIC such as the Intel CT gigabit card.

I finally made the jump for the update from 6.2.1-23824 Update 6 to 6.2.2-24922 Update 2, i only use a custom extra.lzma without i915 drivers, and everything work nicely, onboard Lan, HW transcode, i even made some test with geekbench to find out if the cpu burst work and its a big YES ! With the turbo states OFF in bios > https://browser.geekbench.com/v4/cpu/14202331 With the turbo states ON in bios > https://browser.geekbench.com/v4/cpu/14202575 *I made 2 bench of both turbo state to be sure. For the custom extra you can find it with instruction in this topic >

На 8.2.2 все оки доки.

From this thread, It's made by real3x. It has the i915.ko and the drm*.ko's removed. I too have a j3455 so I wanted to play with it. extra.lzma

You just see the "duplicate" extra when you unpack the extra.lzma ( cpio -idv < extra ) You' re right for the firmware, i'll test to remove then and see what's loaded. Nice ! but i did not make a lot, i just removed a driver

Just correct cpu information view It does not affect performance or anything.

My guess is that the maximum thread represented in DSM is 8. I have not had a system with more than 8 threads, so I have not checked, can you show me the full results of your system cat /proc/cpuinfo ?

Today Update!! Download Available Right Now !!!

Dear Xpenology forum members, I'm come back!!!! I have been very busy at work. So I could not cope with the changed code because I could not upgrade DSM. But! I have recently successfully migrationed the "ivybridge" of existing my systems to "haswell". I also added an additional LAN card. The latest version of "DSM 6.2.2-24922 Update 2" is now available for the DS3615xs, 918+ and other versions. I'll be updating and distributing the "ch_cpuinfo" tool soon so that it will work with the latest version. I'm sorry to have kept you waiting so long, and thank you for waiting. See you soon. Dear @Polanskiman , Thank you for your patience and care for the topic I could not manage. I'll update soon. Dear @gericb , Thank you for your concern and supportive mentality

Try my extra : (no need to disable anything in bios) Change of this extra.lzma > - removed drivers i915.ko drm_kms_helper.ko drm.ko in usr/lib/modules - removed reference of this drivers in etc/rc.modules Installation > sudo -i echo 1 > /proc/sys/kernel/syno_install_flag mkdir -p /mnt/synoboot1 mkdir -p /mnt/synoboot2 mount /dev/synoboot1 /mnt/synoboot1 mount /dev/synoboot2 /mnt/synoboot2 Remove extra2.lzma and replace extra.lzma by the one attach at this is post in /mnt/synoboot2 Important > clean /usr/lib/modules/update/* - Be careful with the rm ! rm -rf /usr/lib/modules/update/* And reboot. you might not have KP on i915 but you''ll probably lost your LAN, since this motherboard only have an old PCI port, i have no clue about a LAN card in PCI that might work. Alternatively you can use a dongle USB3 > LAN, a one with a ax88179 chips like this one > https://www.amazon.fr/gp/product/B00MYTSN18/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 This chipset work natively with the DSM driver : [ 240.104583] ax88179_178a 2-3:1.0 eth1: register 'ax88179_178a' at usb-0000:00:15.0-3, ASIX AX88179 USB 3.0 Gigabit Ethernet, 00:0e:c6:bd:d5:13 [ 240.118675] usbcore: registered new interface driver ax88179_178a extra.lzma
