Im going to build a new workstation based on micro atx and probably use the Fatal1ty X99M Killer or the Fatal1ty X99M Killer 3.1 version.Now,i coud swear i saw a while ago on the main page specifications that the board coud accept max of 128gb ram but now is changed to 64gb. But,in the memorry list i do see 32gb ram stick that is certified. So the CPU is going to be a i7-6950x(as intel ARC says it can handle 128gb ram)or a e5-2690 v4. I suspect that the available 32gb ram sticks are ECC only so maybe only the xeon is compaible. Leaving all this on one side,my question is if i put 4x32gb ram on the Fatal1ty X99M Killer will it work fine or will i get some kind of a nasty surprice(like system not stable,bottlenecking,ram not recognised by system etc)? Cheers

AFAIK, last time I looked those 32GB sticks are indeed ECC. ECC = Xeon, period. I've previously spoke with ASRock Tech Support concerning your exact situation. They affirm memory is limited by the CPUs max useable. Not BIOS nor even number of slots available, as is the case here.. Your conundrum now in your limiting yourself to Micro-ATX is, due to size constraints, mostly limited to 4 slots. Meaning to hit that magical 128GB it only leaves you using 32GB sticks. Finding those magical 32GB Non-ECC sticks will be a walk down a very dark rabbit hole. Then, when you do, pray for compatibility. If you're dead set on using ECC go with the Xeon and those 32GB ECC sticks on the QVL. Provantage here in the US has them for $162.14 USD + shipping. |

Sorry but I don't have any personal experience with 4 x 32GB of DDR4 memory in the boards you mentioned, or any other board. I doubt many other people do too, so knowing what would happen is impossible. The 32GB Crucial memory in the Fatal1ty X99M Killer Memory Support List is ECC memory. They seem to be sold singly, so no need for a matched set? Intel has a document about memory validation with the Xeon E5-2600 v3 processor family, and high capacity ECC memory. But notice the number of slots on server boards. A board with one slot per channel, and not built to server grade, will be unlikely to handle it. http://www.intel.com/content/dam/www/public/us/en/documents/platform-memory/ddr4-rdimm-xeon-e5-v3-validation-results.pdf" rel="nofollow - http://www.intel.com/content/dam/www/public/us/en/documents/platform-memory/ddr4-rdimm-xeon-e5-v3-validation-results.pdf ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Most likely not. At least in the limited production I'll bet they initially ran. And if I may continue with my assumptions, I'll bet the chips used are all of the same production/lot/binning. |

Thanks guys.I will probably go with the e5 2690 v4 but will try and contact crucial and asrock holping some of them made a test.Its possible that in the end i chicken out and go with 64gb ecc or buy the 32gb one from amazon do the test, and if somethings wrong try to return it fast. By the way,from asrocks list http://www.asrock.com/mb/Intel/Fatal1ty%20X99M%20Killer3.1/?cat=Memory Can someone recommend me some good 4x16gb kits ecc and non ecc? (i suspect the Fatal1ty X99M Killer/3.1 and Fatal1ty X99M Killer are the same board just with the usb add on) Cheers

So this morning i receved a message from Asrock. ¨We just tested the crucial CT32G4RFD4213.36FA1 which on the support list with 4 DIMMs, the system can detect all 128GB, please refer the snap shot. PS: Please be noted that only Xeon series CPU support R(Registered)-DIMM.¨¨ http://postimg.org/image/6xh8l4hd7/" rel="nofollow">  Looks like the thing works.I wonder why it says micron.Do they fabricate the crucial sticks? So, a quadruple 128gb + a e5 2690 v4 and probably a quadro m5000(as im offered one at a discount).and 2 ssd Shoud i be expecting some bottlenecking on something? |

Crucial is wholly owned by Micron. Take a gander at Crucials homepage, at the Crucial logo on the upper left corner. http://www.crucial.com" rel="nofollow - http://www.crucial.com |

Note taken hehe. And now for a probably dumb question.In the image above,did they overclocked the ram?

I almost said, did you look at the picture? But if you aren't familiar with an ASRock UEFI on an X99 board, how would you know? That's the Main screen in the UEFI, which shows, among other things, the DIMM slots populated with... uhm, DIMMs, memory sticks (I hate saying sticks), and the speed that the memory is running at. We can see it is at 3000. The Crucial part number is CT32G4RFD4213.36FA1. We can see 2133 (oddly) included in the part number. Just to verify, just search on the part number above. One result example: http://www.serversupply.com/products/part_search/pid_lookup.asp?pid=272137&gclid=CPPohMXNps8CFdgMgQodhkoHFQ" rel="nofollow - http://www.serversupply.com/products/part_search/pid_lookup.asp?pid=272137&gclid=CPPohMXNps8CFdgMgQodhkoHFQ The standard speed of this memory is 2133. I don't think ECC server memory would have an XMP profile, but who knows. Clearly, the memory is over clocked. It may be manually over clocked, which is no big deal to do. What is a big deal is 128GB of ECC server memory used with a Xeon E5-2650 v4 (a Broadwell Xeon) processor being over clocked to 3000.   IMO, to expect 128GB of this memory to be able to over clock at all is...  Oh wait, we don't know what the timings are, might not be good enough.  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Not on either of you twos lives is 128GB 2133 ECC OC'd to 3000. O_and_N, am I sure your building a production box or a gaming rig? Convince me. One simply doesn't build a production box around overclocking its components. They don't. That 3000 there is most likely an anomaly of production. My money's on they needed to select 3000 binned chips for quality, considering the number of chips on each stick, to run reliably at their rated 2133 speed. I don't believe for a split second they're running 128GB ECC overclocked to 3000. Impossible. Just impossible. Not ECC and it's extra bit. Anomaly. Period. |

The actual P/N is CT32G4RFD4213 . I suspect from the . period right is related to production tracking. http://www.crucial.com/usa/en/ct32g4rfd4213" rel="nofollow - http://www.crucial.com/usa/en/ct32g4rfd4213 |

Mmm, sorry. That wasn't meant the way it got typed out. Your choice of a MATX board, particularly a gaming board, is..... well.... perplexing. Are you aware ASRock has a subsidiary that produces actual MATX server based motherboards? I'm guessing not. http://www.asrockrack.com/general/products.asp#Server" rel="nofollow - http://www.asrockrack.com/general/products.asp#Server Then on the left select Micro-ATX as the Form Factor and then 2011-3 as the CPU Socket. |

You could be right about this. I was simply explaining how the Main screen in the UEFI shows the memory speed once it is applied. Now I see why the OP asked if that memory is over clocked. Not a dumb question. I would think ASRock would have said in their message to the OP that the speed of 3000 is an OC, or a bug in the UEFI when ECC memory is being used, even with a Xeon processor. Given these two scenarios, and the lack of an explanation, I must choose a bug in the UEFI. Or it was able to POST (??) but not boot an OS at that speed. To play devil's advocate  , the 3000 speed shown, if an anomaly, seems rather a random number. Sure there is 3000 speed DDR4 memory, but that is a more unusual speed.I can't figure where 3000 comes from, not a multiple of 2133, or the actual frequency of 1066MHz for DDR 2133 memory. Regardless, the 128GB was recognized on a mid-range M-ATX X99 board. That speaks to the quality of the build of that board. In this case, being a smaller X99 M-ATX board with only four memory slots, is an advantage. Also, the memory controller on that Xeon CPU is capable of handling 1.54TB of DDR4 memory! Sounds crazy? See for yourself: http://ark.intel.com/products/91767/Intel-Xeon-Processor-E5-2650-v4-30M-Cache-2_20-GHz" rel="nofollow - http://ark.intel.com/products/91767/Intel-Xeon-Processor-E5-2650-v4-30M-Cache-2_20-GHz Perhaps that gives it great over clocking mojo, even with ECC memory. So ECC memory has a parity bit, and other features for error correction. Why does that prevent operating the memory at a higher speed? Sure, it's not done for stability reasons, but why is 2133 safe, but say 2400 not? This Xeon CPU is rated for use at memory speeds of 1600, 1866, 2133, and 2400. When is a certain speed an "over clock"? When it is beyond the specs for the device. At one time not long ago, any speed above 1600 was an over clock. Just sayin'  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

What's Doo have to say on the OC matter? Or no ECC experiences? I just trolled though countless server manuals over at asrockrack and as I thought, as I have practically zero experiences with ECC myself, there's no mention of XMP in the text nor BIOS pics. Server memory is to be stable, not OC'd. A simple JEDEC programming for them to set up correctly is all that anyone buying these would be expected to look for on booting the first time. Hell, in all honesty I can't think of one reason one would change anything beyond defaults. Stupid and risky, all things ECC server memory related. Stability. Not something one would have to monitor. Nor tweak. Just like the Energizer Bunny, they just run and run. Plug and play. |

Hello guys.Yeah, I have no experience with a Asrock Uefi and frankly I have more experience with how to put the expensive parts to use rather than things like overclocking,and uefi settings.Thats why i tend to keep things stock and stable. The reason im interested in a micro atx motherboard was because im planing on building in the next 1-2 months a sff workstation and be able to take it with me in a small backpack. I know Asus have a nice micro atx x99 one but for some reason I thought that since I noticed that Asrock tends to support Xeons more, than i might get a litle more quality piece. The pc will be used to finish my game in the unreal engine 3 (and serve as a base for UE4 in the future)and the 128gb ram are going to help me with a process called photogrammetry which is a ram hog.I will be importing and rendering between 500-2000 photos 50mg(or more)per photo. For the unreal engine i know that from the xeon when tesing i will probably use only 2-4cores but when i start to render the final scenes, the more the better. Wardog,thank you for the link.Just took a look at the micro atx they have there and some how im not sure if it is what i want.It says it needs a narrow type CPU cooler and i was planning to put a noctua NH-D15 / or NH-C14S on the e5-2690 v4(no water cooling).And i find the Fatal1ty X99M Killer/3.1 to be more feature rich/balanced for the gaming/game dev part and the rendering part. I hope im not mistaking. By the way, this is a really nice forum |

Meh, are you sure? Those coolers are a lot of mass(read stress on a motherboard) to be transporting via backpack. Particularly the C14S as its heatpipes unfortunately allow it to unbalance any loading to only two of the four mounting holes. Unduly stressing one side of the cpu socket/motherboard. http://noctua.at/en/products/cpu-cooler-workstation-server/tdpguide" rel="nofollow - http://noctua.at/en/products/cpu-cooler-workstation-server/tdpguide ^^ Excellent chart. I'd look for the shortest (edit) that has heatpipes protruding from both sides of the cpu plate (stop edit) that meets the TDP of whatever Xeon you decide between here and build time. The shorter the better. I mean, c'mon. That backpack will one day too soon be heavy and a particular PITA that day, only to be nonchalantly flung by its straps over and out of the way. At which point you will gasp aloud and your heart will sink, displacing your intestines.  |

Small udate.As i asked asrock about the 3ghz thing and if the board coud be stable for days with this ammount of ram. Copy/paste --------------- Dear customer, Thank you for the feedback and query. Well, it's able to run with 128GB with CT32G4RFD4213.36FA1 but should not be DDR4-3000. The Xeon series CPUs are not able to overclock, and the R-DIMM memory (Which mean CT32G4RFD4213.36FA1) can only support up to DDR4-2133, so there must be some misunderstanding or mistake. However, we tested when installing 128GB memory with CT32G4RFD4213.36FA1, the system can pass memory test for few days, so we believe it can work well as you wish :) Thank you for your patience. If any, please feel free to contact us! Kindest Regards, ASRock TSD ------------- So it sounds good.I still have a small strange feeling in my throat but is understandable.So by default the e5 2690 v4 is not supported by the onboard bios.And when i get that i wont have a second cpu to make the update.So this is done by purchasing a bios chip(if its not soldered?)or i saw something about updating with a android phone?(but im not sure what motherboard was that method for).
