Hi guys, im looking to pick up a budget server mobo and corresponding CPU, it doesn't need to be anything flash but does require the following: -ECC Ram support -a minimum of 2X8 pcie lanes (16x 2 slots with minimum 8 lanes each) for SAS and SFP+ cards NVME m.2 slot In my local market I have found this: ASRock C236M WS Micro ATX https://www.asrockrack.com/general/productdetail.asp?Model=C236M WS#Specifications

Hi i try to build an pc with ECC memory. I have an asus pro ws x570-ace motherboard and a ryzen 5 3600X processor. The first ram i tried didn't work - the "DRAM-LED" on the motherboard was Yellow an nothing happend. Now i have a RAM that is officially supported by the Motherboard (HMA82GR7AFR4N-VK), and i have the same issue. Is there a Bios setting i have to apply? Now ECC support is set to "auto". With memory form an other PC the System is booting, so the motherboard and cpu work fine. Any ideas to solve this problem. Thx, spitzbuaamy

Hi everyone. Here is a strange problem that you might be interested in. Welcome to send any comments and I will update my debugging process (and communication with vendors, if any and if possible). TL;DR for problem description If all those conditions are met: RAM is inserted in DIMM_A1 Stable Load (0 load or 100% cpu usage is okay, as long as it is stable) Then on my operating system (Linux 5.11.10-hardened), after each 5'14'' (which means 314 seconds, or 100 * pi), there would be an ECC CE (correctable error) on random page/bank at random offset.

However, those (physical) modifications are not ready yet so here is its workbench now: Measures taken and results Clean golden fingers: CE continue Swap RAM to DIMM_A2 or DIMM_B2: Won't boot (as expected) Swap RAM to DIMM_B1: No future errors but I just don't want to use B1 since the problem is just hidden, and I hope to add more memory later Run memtest86 (both the Freeware version by PassMark, and the FOSS version memtest86+) and: RAM at DIMM_A1: FOSS version would fail at random block in first 1M if SMP is enabled, but if disable SMP or change SMP mode to round-robin, no error is reported Freeware (paid) always pass RAM at DIMM_B1: Same as A1 A2/B2: not bootable so N/A Run stress and memtest for memory pressure test under Linux: Errors would be more/less at first, but after ~10min (which means 2 rounds of error), CE continue When DRAM at A1, push forces to the motherboard itself genteelly by following ways, CE continue. Ways are (DO NOT TRY THIS AT HOME IF YOU DON'T KNOW IR SOLDERING): Loosen/Tighten CPU cooler screws Bend the board at less than 2 degrees Read the whole BIOS settings, related manuals, but found nothing looks reasonable for me Suspects I think at least one of those parts is faulty (sorted by possibility based on current findings): Software problems, including The default BIOS settings for this motherboard will cause false alarm for Linux MCE related subsystem The default BIOS settings cause the data being changed without properly set ECC bits Linux MCE things is just not working on Ryzen ...... Software problems is really possible, since 314 seconds looks like something periodic, not random CPU memory controller for channel A (mc0) is broken (which means, RMA ). I think in Ryzen, memory is directly connected to CPU and if I put memory on channel B (maybe another MC?), runtime error disappears. So mc0 seems suspicious. RAM is not stable DIMM_A1 is much shorter than B1 so due to some magical physical things (reflection, etc.) an unstable RAM is possible. Additionally, the vendor of this RAM is also suspicious, and I have never brought things before. Motherboard trace is broken, including traces from A1 to CPU, B1 to CPU, and the DIMM slot to motherboard This is reasonable because when I got the motherboard, the package seems treated violently, although the internal box seems fine. CPU Socket connectors are not in good contact Least possibility. By the pinout diagram (source), MA_* pins are really near MB_* pins, and even located more insider. Affected by EMI Can't explain why B1 works. No high-power devices working near me. To-Do List Try if Windows (PE) have same system logs (if they can generate any, hehe) Re-plug CPU Contact AMD and ASRock for help since I'm not sure if this is really some hardware problem Try a new memory Try a new CPU The most interesting thing is: Why 314 seconds? Is this a periodically thing, or I just treated it wrongly? In my experience of R&D, even if I need some counter for, like drawing an circle, I would use 2**n instead of pi since this is how binary works. Oscillators generating sin wave also don't really use pi, although the sin function have some historical relationship with it. This makes me think maybe those CEs are some software bugs, not hardware problems. But why would this happen.... I spend about 16 hours continuously to change sockets, read kernel source code... but still have no idea about it. Anyway, thanks for everyone's help and I hope if you have met things like this before, you could give me some instructions. It would be better if some engineers from AMD, Micron or ASRock is interested in this. Totally pi**ed off, izumi_konata

I have more than 16 of these 16GB sticks of DDR3 RAM. They are ECC. can somebody tell me if they will work in normal boards ?? Model of RAM : KVR16LR11D4/16 I really have no use for them and they are just lying around with me. if they are worth anything. I wanna sell them. please suggest.

i have a server that used to run a bunch of VMs (2697a v4) with 64gb ecc ram, now that it doesnt need all those cores, i need fewer higher speed cores to host some game servers, i have a 5930k, can i just throw that in the board instead of the 2597a v4 but still keep the ecc ram, will it just run as normal ram without being able to use the ecc features? or do i need to get new ram?

Okay, so I'm new to this page, but I've been a tech enthusiast for many years. I know a base amount about how to build computers and how everything works. But one thing I admit is that I am not an expert, but I have big ideas. But anyways to my questions... I really want to build a new computer that fully supports ECC. I know it's one of those things that really doesn't matter to some, but I'm looking to go for a computer that is built to last, and also is going to have a simple RAID set-up, and an external firewall in addition to the one in the software. I am trying to do something well maybe is a bit insane. So please I ask ppl to be open minded. I need to know how I can modify a pc to run 2 separate raid set-ups that doesn't necessarily need to be able to function at the same time. See I'll be running 2 different operating systems, windows vista & the other is optional maybe windows 10 or 11. Most likely 10. I'll switch between hard drives in the bios with the bios set to run at start up. And I want a back up hard drive set up for each OS as the RAID. And, because I'll be running an older OS I want to add ECC support to help with any errors caused by outdated software, drivers, or whatever. I know I'll get a lot of responses about why in the sam hill I need this kind of set up, well, lets just say I'm married and my wife is quite attached to an old game her siblings used to play a long time ago. Anyways, moving on lol. Due to the older OS that's why I am also adding an additional firewall hardware on the network since it's likely Windows vista isn't updated with the latest protection anymore. As far performance in hardware I'm not necessarily looking for high end, but something in-between, not too hot but not sub-standard either. I did a little research already and I guess AMD still has boards that still enable ECC, and that most or maybe all intel ones don't anymore. My preference is at least 10 cores for the processor with a base clock of at least 3.2 GHz. And at least 64 GB of memory. I'll be using this pc for a lot of moderate and occasionally heavy processing operations, mostly on the windows 10 OS. So first things that come to my mind is does all the hardware need to be ECC compatible? I would assume so, like the CPU, motherboard, ram, and I wonder about if ECC would be necessary for the GPU?... probably not idk u tell me. I'll only be using a basic GPU not for gaming primarily, but more for a modest touch in capability, and streaming. What should I do to prepare to put together a rig like this? Any Adaptors? Drivers? Reformatting? Details beyond the normal standard knowledge of making a pc is what I'm looking for. Even if you don't have the complete list of answers if you at least know one piece of the puzzle it's appreciated. I know what I am looking for I just need some guidance on how I may implement my ideas here. I know how to build a basic computer, but just not with any of these additional crazy stuff lol. I'm open to anything that'll make this happen, even if it's out of the box thinking.

Does Ryzen 5600G support ECC Un-buffered DDR4 memory? Or do I need pro model Ryzen apus to support ECC Un-buffered DDR4 memory? TIA

Hi, i'm a noob at building NAS (TrueNAS) servers and i would like to know if using the Gigabyte GA-H270N-WIFI and i3-7100 / i3-6100 would allow me to use ECC memory, i know that skylake i3s do support ECC, the gigabyte mobo support up to 6 sata connections + 1 nvme but it says: Does this mean that if paired with an i3-7100 / i3-6100 it would get ECC support or its a waste of money and time? PD: the mobo/cpu combo can be obtained in less then 160usd which is great value imo, thanks for the help.

I got 4x16 gigs of ddr3 ecc ram offered from a friend for almost free. As I've been planning on building a second pc for home server purposes, I bought them. Although, my problem is that I can't find any decent motherboard that supports it. I'll be building it on my own, have no other components other than the ram yet. What are my options for a good motherboard and cpu combination, if there are any, that support it?

With 2021 releasing a plethora of new Ryzen gaming laptops - and Ryzen supporting ECC at the hardware level - could we get ECC memory working properly in one? Would we be limited by the mobo? Has anyone attempted it yet?

I am hoping someone here can help give me a lead on what memory to purchase for my supermicro X11SSL based NAS. I am trying to find a 64Gb kit and coming up empty. I am scowering the internet (eBay, PCPP) but the only kits I have found are fully buffered, out of stock, or extremely expensive. Does anyone have a good tool/resource for sourcing unreg ECC DDR4? Thanks in advance!

Budget (including currency): doesn't matter Country: India Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): i have everything, I am just looking to buy some memory Hello, I want to upgrade my ram from 4GB to 8gb and I am looking to buy some ecc memory because it's cheaper than regular ram but I am confused on what type of ecc memory to buy (registered or unbuffered?) My PC specs: Celeron G1840T(supports ecc memory) 4GB OCZ platinum DDR3 1066 Intel HD graphics PlexHD Q87 motherboard

I am currently switching from my bootleg "server" to something high quality and was wondering about Timetec's memory compatibility. The server will be running an R7 2700 cpu and asrock b450m pro4 matx (supports unbuffered ECC). I am under the impression that if the motherboard supports the memory it should work, but the memory manufacturer does not list my board under their supported hardware. https://www.amazon.ca/Timetec-2400MHz-PC4-19200-Unbuffered-Upgrade/dp/B07NQ2PRJT/ref=sr_1_5?keywords=Unbuffered+ECC+ddr4&qid=1644957887&sr=8-5 Could someone enlighten me?

I'm working on my first PC build, and the X470 Gaming Plus Max ticks all the boxes. Only problem is that I don't know if it supports ECC SSDs. I'm using the Team Group MP33 which does use ECC. I would rather keep ECC and find a different mobo than get a non-ECC SSD, though changing the SSD might be easier.

Budget: <$1000 (cpu, ram, mb, gpu, case, psu) Country: US Games, programs or workloads that it will be used for: homelab server Purpose I think it's the time when I outgrew the good & old HP Microserver Gen8 with all the upgrades possible.

I'm slightly out of the PC hardware space for a few years now. Putting this build together took me a while. Any comments/suggests/changes you can suggest?

Hi, I'm building an entry level server that will be mainly running a whole bunch of node-red automations, hosting influxdb and grafana. In the future, there will more complex automations running on the system with the possibility of machine learning and image processing. Currently, This server will be running 24/7 for at least 5 years. I need a simple reliable server at a budget that has room for upgrades. I have looked at server grade processors which are far over my budget. Hence, I plan to go with a Ryzen 3. To make the system more reliable I would like to use ECC RAM. Based on the ASROCK B550 Pro 4 page, Renoir APUs support ECC RAM. Will a normal Kingston DDR4 PC2666 ECC 8GB RAM work in this system? The main reason why I'm going with the pro series because its stated that only the pro series supports ECC, is this true? PS. Is there any other things I should look out for to make the system reliable and running continuously?

Well hello there, I'm currently searching and conceptualising a new computer build and I'd like to hear any recommendations you guys have. For some context, I work in the cybersecurity industry so I'm trying to figure out a multipurpose workstation. My main hardware needs for my workflows are high CPU core counts, best connectivity and as much/fastest ram as possible. I do a huge load of code compiling and machine learning, also constantly have whole virtualized networks. And, I'm also a bit of an audiophile so as a hobby I tend to do a whole lot of playing with audio tech. But here's the thing, I'm the kinda guy thats had the same computer since 2011 and keep upgrading it constantly throughout the years (Dual Xeon Mac Pro) so I want to build something that'll last me potentially another ten years. I'm guessing for high core counts and ECC im stuck with Xeon, and I also really want to be able to expand the ram to the TB's at some point. My main focus would be future proofing in every aspect, so id love to hear any recommendations you guys might know about. My wishes would be: -Hardware: TB ram expandability Minimum 4 Pcle x16 (gen 5 available anywhere yet?) And as many more as possible As many nvme slots as possible (raid capable) ECC memory -I/O: Minimum 6 Sata connectors for HDD 10gb Ethernet USB 3.2+/thunderbolt Optical interface (to not need to occupy Pcle) Also, anyone know of any features geared towards direct storage by any chance? Form factor isn't really an issue for me but I'd like to evade going the rack route if possible. Any ideas guys?

hello just looking for some help I'm here trying to build a gaming server and a streaming PC that just encodes maybe later a media server prob not all at once. I was thinking about 4750g for a little mini ITX PC. I was wanting this to have ECC ram and but I'm not sure what to get for ECC so if anyone has suggestions for a build for something this like a hole build that would be great. I the budget like 1500 -2000 this is going to be like a 2nd PC not a main gaming rig.

I’m building a high end desktop for optical design and CAD work. Ray trace optical design is very memory intensive, so I need 256GB. My question is what is the real world difference between ECC and non-ECC RAM? I have been doing this type of work for a few years on an Intel x99 system and have only encountered BSD twice. Comments and suggestions appreciated. Basic build: MOBO: ASUS TRX40-XE CPU: Threadripper 3970X RAM: 256GB GPU: Quadra RTX 6000 Boot: Samsung 980 Pro 512GB Data: Samsung 980 Pro 1TB

Hi there, I build myself a small home server with a Ryzen 5 3600 and a MSI x570a pro. Now I want to upgrade it to ECC RAM, because I want to save my ( more or less ) important files there. I know that I have to get myself a new mainboard with ECC support. But I am not sure if I should stick with AMD and try, if Rhyzens really support ECC or switch to a, lets say Intel XEON Setup. Btw. My sever should be as quiet as possible cause it stands in the room i sleep too. And I dont wanna sleep in a Server Room with loud noises. Hope someone can suggest me something.

Hey Guys, I'm planning on Building a Nas in a Node 804 Case, I've been looking around for decent uATX mobos and found myself hanging between Intel and AMD and the support for ECC. AMD unofficially supports ECC but mobos seem to be hit or miss. Do i even need ECC? I'm on a strict budget and I've been suggested B450 Aorus M and Asrock B450M Pro. All i want is a functioning Nas for Data Archival and Casual Plex usage. Having atleast 6 sata ports and PCie lanes that do not share bandwidth with either m.2 slots for GPU, hba and 10Gbe networking is also planned. Please help.

Hi all Assuming i have a bunch of the memory sticks from this picture, a proper gpu, m.2 drive and ssds, Could i use them in a ryzen (zen 2 based) And a x570 board build? My plan is to build something that would reduce some of the costs at first and then slowly upgrade (cpu, gpu, memory) over time when budget allows If this is indeed possible, which x570 board would do a good enough job and have 4 slots of memory to use, so that when i do upgrade to higer speed memory, i can use regular (but high speed memory) and have enough capacity

What kind of RAM do I need for a Intel NUC 11 Essential Kit NUC11ATKC4? The specs say DDR4-2933 1.2V SO-DIMM. I looked at several vendors and 2933s seem to be very rare at SODIMM configuration. For ECC SODIMM however there seem to be lots of 2933s. Does anybody know if I can use an ECC RAM on this Intel NUC Kit (CPU: Intel Celeron)? For example the Samsung M474A1K43DB1-CVF? Or which RAMs would fit here? Btw. I want to have 8 or 16GB in dual channel.

EDIT: If anyone finds this after all this time, I managed to get it to work with 4x32GB Dimms. I had to reset BIOS multiple times until the System was willing to boot.

Does anyone have experience with using ECC RAM on Ryzen? I looked at the supported RAM for my Mainboard, which seems to support Unbuffered ECC RAM: https://rog.asus.com/motherboards/rog-strix/rog-strix-x570-f-gaming-model/spec/ The cheapest Unbuffered ECC RAM per GB I found was the Kingston DIMM 32 GB DDR4-3200 ECC (KSM32ED8/32HC). Can anyone approve, that this will work with my setup? Thank you!

hi, i have some loose memory modules from some older servers that i need to identify if are : ECC Unbuffered ECC Registered But i have no idea how to check that. Example: SK Hynix 16GB 2Rx8 PC4-2400T-RE1-11 (HMA82gr7afr8n-uh t2 ac 1838) Anyone know of somewhere to find this info? /D
