Machinist X99-MR9A (Pro) - my favorite LGA 2011-3 motherboard from AliExpress

[@Miyconst]

It turns out that I have missed one very important detail: X99-MR9A Pro has 8 phases VRM while X99-MR9A non-Pro has only 6 phases. The MOSFETs are and their configuration is identical between the motherboards.

[@eduardomartins8186]

Chinese X99 mobos do not have X99/C612 chipset, so this is a poor source of information

[@andrewsturmey]

Certainly correct for most of the boards. Some of the Chinese dual-socket ones do use C612. That's my only real interest in this scene, admittedly.

[@uzerek]

@@andrewsturmey I've been on the subject of lga2011 for two years and only recently I find out what the real chipset is. it's sad, I watched a lot of materials on YT and no one mentioned this little detail. I'll watch your video now.

I had no idea what I was buying with my first board, and it was a bit of a disaster. I've done three videos on “X99” stuff now, and come to realise it's definitely a false economy. Fun though. Definitely cannot trust the people who manufacture these boards, mind you.

Thank you for your very informative video. I bought this motherboard at a good price and built a second X99 computer for general use. I watched your previous MR9A video. Furthermore, I tried to use the non-ECC bus 2666 Kingston Fury RAM, but it did not boot up. So I went to the ECC ram, and it boots normally. Have a great day, and keep up the good work.

Hello, did this happen after flashing the bios from ieng?

[@greenprotag]

For around $50-60, these boards still represent a fairly good value when paired with a well priced v3 Xeon. It's just harder and harder to recommend paying $100-150 on the Xeon v3 platforms when used Ryzen is also fairly affordable. The big attraction for me is dual x16 slots AND dual NVMe drives with 40 PCIE lane v3 CPUs

Very true, paying premium for a "high end" X99 motherboard from AliExpress makes zero sense.

Yes, you can use the 8 pin PCI-E connector in the 6-pin.

valuable info. Another Great vid

MR9A has 2 smart fan ports that works, CPU and sys header. You can control it using a open source software like fan controller and you can set a curve and temperature sensors. I tested and works perfectly with any pwm fan.

sys is 3pin so it works through voltage regulation? does it work with Linux or the bios fan curve?

[@tyrellwreleck4226]

Techyescity also mentioned this in machinist motherboards. Unlocking turbo boost is a pain in the butt cheeks. You have to double the step and there's a chance that the bios may break. Also it sucks that its temperature sensors doesn't work. Most of us can't afford a thermal camera

I still don't see the X99 MR9A Pro listed in your Mi-899 program. Which makes me wonder how you were able to flash the MR9A Pro BIOS, when you don't seem to specifically share a link to explain the flashing process described as "working really well" in this video. It's not in your blog either, I looked. I just can't take a risk on using the wrong BIOS for my main PC right now. Is this a blind spot? Or did you simply not mention that the old X99 section and BIOS options work for MR9A Pro as well?

[@Miyconst]

MR9A and MR9A Pro share the BIOS. Please download the latest Mi899 app and select MR9A as your motherboard then pick desired BIOS. Also, with Chinese motherboards I can never guarantee BIOS compatibility, even if two boards are called the same and look the same.

[@kansax8253]

I snagged one of these for 45gbp including tax about two months ago. Genuinely surprising, as it was 20 cheaper than the shitty Machinist X99-K9 I bought for 65

[@Miyconst]

Yeah, sometimes Ali prices make no sense but the bigger batch they make the cheaper it is, and MR9A is probably a more popular option than X99-RS9.

[@DrywFiltiarn]

If you had to choose between Machinist MR9A and Huananzhi F8, which would be your preferred board?

X99-F8 if the price is the same, MR9A if we take the current Ali prices.

[@zeukrob]

Three flaws: 1- It doesn't specify it in its description, but of the two M.2 ports it has, one is NVMe and the other is SATA. 2- The sound card delivers terrible audio, and the front 3.5 jack doesn't work for me. 3- The small VRM fan starts to hum very annoyingly after a while, you have to buy a few 30x30x7mm Brushless fans in advance. The M.2 ports don't surprise me, they should be clearly specified. I've tried audio drivers but I haven't been able to do it. Two years with it.

[@Miyconst]

Yes, the older revisions had one SATA and one NVMe slot, the newer ones come with two NVMe. The sound card and the VRM fan are sadly just poor quality of your unit. AliExpress is a lottery, as I always say.

I wished they made budget 3647 or 2066 motherboards for AVX-512 dependent workloads.

Have you encountered an issue with this board as below, Whenever I open device manager I see heaps of base system devices missing etc The moment the system seems to check or scan devices it immediately reboots. It is Windows 10, fresh install I am struggling to ensure all devices are installed. It also reboots the moment I try and install drivers from AMD adrenaline, and the audio driver link you have included also.

[@glimmerman101]

I managed to get all drivers installed but the one problem I still encounter is if I run AMD adrenaline installer (I have an RX 6700 non XT) the moment the installer opens, I hear the hardware disconnect sound and the PC restarted itself. Now after a few windows updates, it restarts and then immediately after I see it complete post and windows loads, windows goes straight to "shutting down" and repeats the cycle. Very frustrating, I was very excited to get to use this. Taking up so much time with clean OS installs and iengineer bios flashed, still can't crack this problem.

[@Miyconst]

It sounds like you may have a hardware failure. In general it's enough to install all Windows updates including the optional ones.

[@glimmerman101]

@@Miyconst I've installed all Windows updates and optional also. I'll flash back the original BIOS and try and return it. But I'll also make sure it isn't a compatibility issue with my GPU being too new. I did however to get all drivers installed need to use PowerShell to install them in bulk as the second a program seems to state "your device needs a restart to complete installation" the PC immediately reboots. Might even be the PSU perhaps as it keeps stating "PC has woke from low power state" or along those lines. Troubleshooting... Such a pain Thanks for taking the time to respond.

[@Andre-uf9lj]

It depends on the game. But on 1440p ur most likely to be GPU bottlenecked. I would suggest the E5 2680v3, pretty decent Xeon i think.

[@Miyconst]

It really depends on your budget and wishes. In general, the higher resolution is the stronger GPU you need.

[@-_-DatDude]

If you're going to build a Xeon gaming rig, prioritise higher clock speeds and high single thread performance over insanely high core counts bro. Its also worth mentioning that most games don't benefit from the level of multithreading peformance that the 12 core,14 core, 16 core, 18 core, 20 core and 22 core Xeons were designed for. I made the mistake of buying a 2698 v3.😂😂🤦‍♂️🤦‍♂️ What the X99 community wont tell you, is a lot of the higher core, low clock rate CPUs more or less requires you to flash your bios and undervolt your CPU so all cores are in turbo mode for optimal gaming. Undervolting and flashing your bios is not something a first time PC builder should be worrying about imo. The post is getting long so I will state my recommendation...Go for a 1650v4 or go 1660v4 if you are obsessed with more cores. Anything else and its more of a workstation than a gaming rig.

[@Miyconst]

@@-_-DatDude please watch this video before recommending E5-1600 V4 CPUs: kzbin.info/www/bejne/aIHSf56PeMuCmas

[@-_-DatDude]

@@Miyconst In fairness, the higher core V3 CPUs that you tested were either overclocked or you flashed your motherboard to enable turbo on all cores. So its not the fairest test as you cant do the same on the V4's. It's worth mentioning that not everyone is as confident or as skilled as you are at tuning their rigs as you are mate. I'm purely talking about out of the box performance here mate. The out of the box clock speeds are too slow 🐌 on the higher core Xeons for gaming. Im not going to be disrespectful and mention other KZbin channels on here but let's just say I've seen other videos on KZbin were the 1600's V4s consistently beats the other Xeons *WITHOUT TUNING* in most games that are more optimised for GPU.

Sure about what? Yes, X99-MR9A uses desktop chipsets randomly.

About it to be a 'go to motherboard' :-) No offense, but depending on the Chipset, some motherboard have strange behaviors :-) For instance, if one tries to setup a Raid10 with spare drive across 6 drives, using SSD.. flipping coin constistancy :-) If you're only interested in gaming, maybe it's a good choice, but if you plan on something else, I'd chose Another motherboard, be it Machinist or not :-)

If you are looking to RAID your drives it should be done with software, if you need reliable hardware RAID support you should use appropriate hardware for that, for example Dell T5810/T7810 workstations.
