Supermicro AOC-SLG3-2M2 PCIe Add-On Card for up to Two NVMe SSDs

Thanks, very nice! You answered some questions about this cards and how it works!👌🏻

Thanks a lot! I bought a Supermicro AOC-SLG3-2M2 now. (:

What language is this man speaking "delineation"?

thank you for the info, I benefited a lot from your video.

does this card work with aorus b550 slot labeled pciex 16 slot (pciex4) integrated in the chipset supporting pcie 3.0 x 4 mode?

Do you have anything against the M.2 slots on the motherboard? You simply have all your SSD's (including the boot) on the PCIe slots?

Thank you for informations!

Will this work in Mac Pro 5,1

Educational gold. Thank you professor

AWESOME CONTENT!!!!!

Hi Bill, Great video, do you know if i can place 2 Firecuda 530 with heat sink on this board? if not do you know any Hyper M.2 PCI-e 3 or 4 with 2 card that can hold 2 Seagate Firecuda with heatsink?

what is the best thermal compound you recommend? do we have any videos testing different thermal compounds?

AOC-SLG3-2M2 is pcie 3.0
980 pro is 4.0
how are you getting these 4.0 rates?

This channel is awesome, no sponsor, no yadda yadda, no flashing colors, 100% information we need!

Awesome video, my 2nd of yours, you are very concise and right up my alley. I am an older user (dos 6.0 with 6.2 upgrade!) and just recently into nVME drives and these videos were very helpfull. I have an Alienware 18 with mSata boot, SLI video and raid 0 drives, no NVMe possible there. My old desktop Gigabyte GA-X79-UD3 however has 4 - pcie 3.0 x 16 slots (2x16 electrical and 2x8 electrical). Installed a Samsung 970 EVO plus in the second x16 slot (8x elec) with a single rivo board and wow, I thought ssd was fast. 3300 read and 3000 write. HWinfo confirms 4x width 3.0 pcie @ 8.0 GT/s.

My question for you is I have installed two separate modded bios to include my new drive and it does boot but IMEI fails to start on either the new Win 10 install (shows PCI Simple Communications Controller error) on my nVME 970 or my old ssd dual boot (win 10 win 7, shows "Intel(R) Management Engine Interface" could not start). Its not a driver issue and I changed my battery. IMEI seems to be very important. Any idea what can be wrong? I have a SSD boot drive with an onboard intel Raid 1 with 2-2tb drives and an onboard Marvell Raid 0 with 2-1tb drives which I disabled prior to bios mod.

what an amazing video... thanks so much!

it's called wind-ow-s not win-da-s....hehe

sir...i really need your help...we are using supermicro mother board H12DSU-iN and AOC-SLG-3-2H8M2 raid card.. But we unable to install Operating system (Ubuntu version 18, 20 and 22 as well). I am ready to give you my any desk ID for support... Please help me

Awesome content! Love the Broadcom RAID controller videos. Keep it up!! (Oh, and that accent is really cool :)

Thank you for the good Video! Dell has no Dual Adapter for M2 NVME-Drives (only SATA). Now I have found one for my R540 (SSD-Cache), thank you!

I have an Aorus Elite x570 motherboard which has 1: pciex16 and 1: pciex4. the x16 is populated by my GPU, so I put this expansion card on the pciex4 slot but it's only picking up one of my two drives on the Supermicro card. Am I not able to do anything even If I run them at less bandwidth? Sorry I'm kind of new at this stuff.

Crazy amount of detail man i actually learned a shit ton. But mostly i Learned that i need a new motherboard

Hello BuildOrBuy. I check my BIOS for bifurcation but I don't see the option. I have an Alienware R11 Z490 motherboard. Is it something I'm overlooking? I would like to use this card for dual Samsung 980 pros with Heatsinks. The only options I see in my BIOS in regards to drives is SATA Operation with a selection for RAID on or AHCI. My BIOS is extremely limited.

Thanks again for your videos.

Thank you tremendously!

Just the video I was looking for.

Could you perhaps some day look at a card like the SuperMicro AOC-SLG3-2H8M2 which has a RAID chipset (And probably a PLX chip on it too) and see if it could RAID-0 two NVME SSD's into a slightly older computer motherboard that DOES NOT have bifurification support and let us know if it would work? It's something I have considered doing but no one on the internet has tested anything like this. And you seem like the sort of person that might be interested in trying something like that. I just found you today with this video and I love everything you have done for us. I plan to spend a lot of time tonight watching most of your other videos too. Please keep doing what you're doing. I found the information you shared here very useful.

The Gigabyte z590 Arous Pro AX has 4 M.2 spots on the board.

So, looking at the results, this adapter, with its gen3 x8 pins, intended in theory for 4GB/s times two(for two gen3 x4 NVMe drives), can actually do gen4 x4 speeds(max 8GB/s, in a gen4-slot), if used, as tested, with a single gen4 x4 NVMe SSD at a time. So it's basicly gen4 capable adapter, if I understand correctly. Just, though, for just one gen4 x4 drive at a time, as the test CrystalDiskMark-test does it, and the LED light showing the same. I think, bandwidth would possibly run out with this kind of gen3 adapter, if we would use both gen4 drives at the same time--as the intended usecase is two gen3 drives. Looking at the test results at read speeds of 7GB/s alone, which isnt possible when using an actual "speed-limiting" gen3 adapter for gen3 x4 drives. Makes sense; the math in theory states: 2 times (gen3 x8 =)8GB/s(rounded up, single gen3 lane being 985MB/s), which equals 1 time (gen4 x4 =)8GB/s(rounded up, single gen4 lane being 1,970MB/s). Very interesting results.

Motherboard speakers...yes...got a bag of them. They tell you up front if it will boot or not.

Thank you 🌹Learning a lot from you⭐️🌹

Thank you for the info and ideas. Bringing us together to intrigue the new technologies.

Love these videos! Your channel is awesome. I wonder if you have addressed chipset heat management, ssd , cpu , northbridge, mosfets ,etc... all dissipate lots of heat thus the need to keep em cool via thermal interface materials and heat sinks/heatpipes, I would love to see a video about the calculation/considerations when choosing TIMs and heatsinks, it’s so strange that most laptops don’t have any heat dissipation on the mostfets , and they get pretty hot and fail easily , I know the basics, but when I want to modify a high end laptop and add a heatsink on the vrm section I don’t know how to choose the right size/volume heatsink.

Hi Gill. 7/29/2021 OK something is up! ebay open box 3955WX hi bid winner $610. This morning new 3955WX $1000, This afternoon $950. IDK no one has any money? AMD's ZEN3 TR Pro is about to hit the market? Dealers want to dump their inventory fast? The dollar is about to take a big hit on the market? Due to a lack of funds TR Pro is not selling? Three years of TR and people still don't even know what the increased I/O will do for them?

the pin for the ssd standoffs goes back into the standoff to push outward the latches that retain the standoffs to the pcb of the card. They kept the pin short because the function was met, and with the pin in place the standoffs cannot be removed readily without the absence of the pin in that position.

This is actually interesting. Even product page show us that card is Gen 3, but in fact it... let's be 100% correct - show us "Gen 4 speed for SSD". Is it mean that card is actually Gen 4? Basicly card is simple (electrical) converter 1x PCI Express x8 to 2x M.2 x4 slots. So, no "special" electrical preparation on PCB level (extra layers or shielding)? Because i know that PCI Express riser cables actually have got stuff inside... well... cables - shielding of the signal. Maybe that shielding is important only for GPU (intense data transfer)?

It can't be that Supermicro don't have PCI Express 4.0 motherboards, right? Thay are big manufacturer.

P.S. But it good anyway, since this is cheap card. Even in my country it cost ~$50. Good for cheap raid experiments (SSD\Optane Raid combos).

Thank you, highly informative. Your videos are criminally underrated. Hopefully, the algorithm will give you the push you deserve.

What about heat sinks or fans for the m.2's? And like Regan, trust but verify. I know they need to be warm but not hot.

Great video with explanation of the hardware and how it interacts.
