looks legit

It's google's cache of Asus's own website, so yes, it is very legit.

What's the big deal with ECC?

Cool.

I don't think I've ever encountered a situation where I wish I had ECC, but it's nice nonetheless.

Ryzen is a forced meme.

Its something Intel locks out and the only real reason is really out of spite to drive Xeon and workstation chipset sales

Higher density modules, high precision workstation applications.

Theoretically, if the board supports it, you could put ~512GB of DDR4 RAM into a board with Ryzen in it (4x128GB ECC modules).

Does this mean we can use registered ECC DDR4 modules when they start selling them off cheap? You can get 4gb reg ddr3 as low as $5 vs $25 for the normal stuff

Why is non-ECC listed twice, I don understand?

Buffered vs Unbuffered, i'd wager.

meant for

Windows 7/8 32 and 64bits and Win10 32bits BTFO!

Annnnnnddd dropped

:/

As much as I would like Windows 7 to stay this shit was coming. Leave it to Microsoft to just not give a fuck to put out a new service pack to support this shit

Is ECC actually useful for consumer use or is it only worth it for people who are running servers on their machine?

Only really useful in certain use cases, the big thing here is the fact AMD is not telling you to fuck off and buy there server/workstation parts like Intel does

It's good for prosumers that run servers on their machines.

Basically AMD tells you not to fuck off for Opterons if you want consumer CPU-based workstation.

Right, but as for use cases in which ECC makes sense, are they only server-related applications or could it be useful for things such as intensive audio/video editing/rendering? I'm guessing ECC would be redundant for games too.

ECC would make sense for NAS/pfsense which do not need server grade CPUs or anything over 4 cores really

That's only registered you moron
It's noticeably slower and never in the past been supported by consumer boards/chips.

It's not like every AM4 mobo is going to support ECC, though. I think ASUS would support it for sure.

Hasn't AMD always supported ECC on everything?

IIRC those APUs lack ECC.

i know xeons use ecc memory but....what use will i have from it?

24/7 server use

Actually that should be a asus issue because biostar listed their X370 with drivers from w7 x86 onward, at least that's for the X370GT3

>uses the word ECC

why do you shit post? trying to lower my productivity by making me google what the fuck ECC is?

>Not knowing what ECC is in the first place

>Intel
>retard nigger

what are the chances to see core boot on zen

If you don't know what ECC is, firstly your time is worthless so 'productivity' being lowered is meaningless, and second you shouldn't be on Sup Forums. Fuck off.

Welp that settles it.
Going Ryzen.

Good, but slow.

phoronix.com/scan.php?page=news_item&px=AMD-Zen-Will-It-Coreboot

They have said all future CPUs will support it in the past. But who the fuck knows.

>Linux kernel module: On.
>ECC active

Due to the extremely volatile nature of RAM, you invariably get errors every once in a blue moon, although it's so rare and limited in scope that for consumer systems it's not worth considering. No one will care if an image you left open in Photoshop overnight will have the color of one pixel change slightly, and a random system crash can be chalked up to bad programming or something you did.

However as you scale up in memory, from a few to several hundred GB of RAM, and have it running 24/7, this multiplies the chance of an error happening considerably. And in a server room of many terabytes of memory you basically have errors happen every second. If you're running a simulation, this could be catastrophic for the results, or if it's a database, you will have wrong data be recorded to disk, even if it's one digit off it could still mean a bank loosing a million bucks worth of customer cash for no reason.

Servers, reliability in general if you don't want extremely fast performance.

cheap af

vga passthrough.

there is so much hype for Ryzen I expect people will legit kill themselves if AMD disappoints yet again

>Due to the extremely volatile nature of RAM

That is easily the dumbest fucking thing that's been said on this board in the last oh, 12 seconds.

>stupid fucking people will be the death of us all

>If you're running a simulation, this could be catastrophic for the results,
To expand, chaos theory expands the results of errors massively. ECC ram is used in weather simulations, because a computation error right near the start would compound on itself over and over again and produce completely inaccurate weather predictions.

Well if Ryzen fails, AMD is dead and intel will strangle x86 for the rest of time.
Basically meaning that ARM takes over and there's no actual reason to continue living.

Didn't the FX line support ECC too? I'd be surprised if Ryzen didn't.

what do I do with my 32gb of 1333ghz ram

Use it. Ryzen supports ECC; it doesn't require it.

They did support ECC, for the same reason. Consumer CPUs are just chips that didn't quite make the cut for the enterprise Opterons. The memory controller has the additional bits for ECC, it just normally isn't used by consumer boards.

Hes not sticking DDR3 in a socket AM4 board.

AMD enables everything on every chip pretty much. They're not greedy like Intel where they strictly segregate features into different segments of the market and make it impossible to get what you want.

He never said it was DDR3

Use your brain. Try. Just once.
He doesn't have 1333mhz DDR4.

Quit being a fucking dolt. Nearly nobody knows all of the possible DDR4 frequencies off the top of their heads.

Since I'm still on Core 2, even if it's a massive disappointment it'll still be an upgrade for me.

The minimum spec is 2133mhz. Its painfully obvious that he was talking about DDR3. Seriously get the fuck out of here and don't come back.

very good, they shouldn't support obsolete inferior trash used by only loud minority autists, called win7 but no win 8.1 support is kinda shit

Again, see >Nearly nobody knows all of the possible DDR4 frequencies off the top of their heads
Eat a dick, sperglord.

after seeing regular ddr4 prices the other week i dont even want to look at ecc prices

you can leave a machine on all day, every day and not worry that bad RAM or random bitflips won't go undetected/uncorrected.

ECC modules are more expensive than non-ECC and generally aren't sold in the higher speed grades, but it's a very nice feature in workstation chips for those who want to built their own file servers, etc., without paying the Xeon tax for support.

This is unbuffered, so it won't correct - but the machine will know the memory is wrong and can act accordingly rather than writing out faulty bits.

Technology exists to prevent silent data corruption.
Do you want it?

>it's not """needed"""
>something something servers
>muh games
t. Sup Forums cr3w -=[MLG]=-

ECC is usually always just about 10% more expensive.

...

>once in a blue moon
>so rare
Meanwhile Google released data showing about 5 single bit errors in 8 Gigabytes of RAM per hour on the high end. If you're willing to risk that with the assumption that "one pixel in an image can change slightly" (never mind the fact that if a bit changes there's a good probability that it's going to be in the high bits and cause a greater change than "slight") then you must not give a fuck about what your computer is writing to your disks. Bit flips in the kernel memory will probably lead to system crashes too, which are pretty fucking annoying unless you're autistic enough to save all the time.
>limited in scope
An arbitrary bit in your RAM can change its value. It's basically unlimited in scope.

Any details on the chipsets? Intel has been jewing us for years on the fucking chipsets.

Dude they announced chipsets back on CES. Just google it.

Ah, the old 'cosmic ray' attack.
Rating: Severe
Description: Vulnerability exists in the case where attackers can control cosmic rays to arbitrarily flip bits in memory.

>Attack
No one said attack, everyone is implying the potential for massive data loss.

There a 0.000000000078125% possibility that one random bit will flip. That's not very massive.

B...but what if it's the 'delete all data' flag?

what are you smoking?
buffered/unbuffered is purely the difference between an extra array of latches right before the bus that enables more DIMMs per channel.

ECC is about using more SDRAM lanes/chips (9 or 18 chips with 72b total instead of 64b) to store redundancy information that the host memory controller verifies. Every write sends the extra bits, every read sends them back, and the memory controller can autonomously read the entire SDRAM array ("scrubbing") to preemptively detect and fix errors.

They're strictly orthogonal things, even if buffering is almost never used on non-ECC sticks.

The consumer use would be for a home built NAS

The most probable thing to be affected by random bit flips is the operating system. It's the only part that is up at all times while the computer is on. User applications are opened and closed on demand so their memory is constantly being refreshed. It's possible but the window for an error to occur and then not be corrected is much smaller.

>What's the big deal with ECC?
People think it's to prevent random cosmic ray bit flips, but it's really more about detecting and correcting for subtly defective SDRAMs long enough to replace them.

Various large scale trials have shown that the majority of errors in enterprise come from flaky bit cells or bit column sense amps that fuck up once a day or week, i.e., not enough to be guaranteed to be caught in manufacturer QA or an initial torture test but enough to lead to probably bugs/data corruption/crashing in a server.

Did you fucking bother to read what I posted?
research.google.com/pubs/pub35162.html
The actual, field error rate is orders of magnitude above the old, assumed error rate.
>0.000000000078125% possibility
That means a lot when you don't have an interval assigned to it. 0.000000000078125% per 0x10^-32 picoseconds?

5bits out of 64,000,000,000bits = 0.000000000078125%

Not sure if I did the math right but there's a very small chance of any one particular bit flipping.

>4 DIMM max 65GB
I can't run exchange server on this

>ryzen doesnt have igpu
>HAHAHA AMD BANKRUPT ETC
>ryzen comes with ecc support
>y-you dont even n-need it goy
>w-whats ecc????

No, 5/(64e9) = 78e-12 = 0.000000000078 = 0.0000000078%

But you calculation is nonsensical in any case.
Like the user above said, you need to express errors in terms of rate per time or proportion of bits transferred. Beyond that, you also need to consider the nature of stored data and that a single bit flip will ruin an entire 64b pointer, etc.

>any one
But your system can use a lot of that RAM depending on what you're doing. Caching to minimize "wasted" RAM will also open up more data to memory errors.

don't worry famalam, you're allowed to stick 64GB DIMMs in the other 3 slots too.

didn't they charge you by the core? how umch did you pay for windows?

Its just Offendows 7 Enterprise. Max 2 physical CPUs and unlimited cores. (this image is a different server from other screenshot)

64 gigs per DIMM?

Things just got interesting.

>20c/40t x2
Noice

MORE CORES

meme

>don't worry guise, just wait for zen+!

>B350 "mainstream" chipset
>4 SATA ports total
Am I the only one who likes to have 6 ports minimum? The enthusiast boards will have 6 but I'm sure those will be $200+.

Nah, X370 starts at very honest 129 burgers.

>nobody knows
gtfo Sup Forumsshit!

There's two included with the Ryzen CPU and Stoney Ridge APUs themselves.

32 GB DIMMs are bad enough, but 64 GB is in pure "money is no object territory". You would be literally better off paying more for a Naples MCM with cores you didn't need just for more memory channels/slots.

Honestly, get a Broadwell (-E or Xeon) just for the extra channels if that's your main concern.

Memorizing a bunch of easily googleable numbers isn't a requirement to post on Sup Forums. And I didn't say nobody knows, dumbass. I said most don't, which is definitely a fact.
