Adapter M.2 Pcie X8 is the best choice?, heeelp!

[SARAH FABREGAS]

Hello i have a gigabyte b450m ds3h and an athlon 3000g, but i want one of those to have fastest load of files of a custom app im using. Not for games.

 

it has the asmedia asm1182e, is this a good solution or is a scam?

 

thanks.

Does your mobo/BIOS support PCIe Bifurcation? You'll need that to see both nVME drives

Does your board support PCIe Slot Bifurcation? You need the ability to run the slot as x4/x4 instead of just x8, as the image you posted notes. I have a similar card from ASUS, the Hyper M.2. It runs 4 NVMe SSDs, so it needs an x16 slot split out to x4/x4/x4/x4. 

 

If your board doesn't support it, you need a card with an onboard chip that will split the lanes itself. IIRC those are $300+, so you're better off just buying a new motherboard that supports bifurcation.

I want to use only 1 nvme slot, do i still need bifurcation if i only want to use 1 slot? my mobo does NOT support bifurcation.

ASM1182e, PCI express packet switch, 1 PCIe x1 Gen2 upstream port to 2 PCIe x 1 Gen2 downstream ports

It'll work but the performance will be pretty bad.

 

For faster performance you will probably want something with the ASM2824, but it's pretty expensive.

That's an understatement...I have two of those cards, each support 4 nVME cards. I love them (bootable no less, on my Ivy Bridge dual Xeon rig) but yeah...pricey

Just get a cheap single M.2 one then, I have multiple EZ-DIY or whatever ones I got off Amazon, ran single x4 drives without issue.

this ASM1182e cost the same as the single solution, hahaha, but i thought ASM1182e is better than single solutions. what is best for me with my actual mobo b450m ds3h since my athlon 3000g does not support nvme slot due lack of pcie lanes in the cpu.

If you only use a single slot, how would it be better than a single slot solution.

Are you running a dGPU or something? From what I'm seeing you should have x8 lanes free. If you're already using a dGPU at x8, then you don't have any PCIe lanes left. PCIe slots use PCIe lanes, so it won't magically give you more lanes to use an add-in card vs the motherboard's built-in M.2 slot.

this is my pc, sorry i recently upgraded from a pentium 4, i dont know new terminology. 

 

im using igpu, but pc store told me amd athlon 3000g does NOT support NVME ssd, is that right?

 

thank you.

You have no other PCIe cards installed, so there should be enough lanes to just use the M.2 slot on the motherboard, no need for an add-in card. 

 

As an aside, I'd also look at getting a 2nd stick of RAM or just a new matched kit, DDR4 is very cheap right now (at least in the US, you can get a 16GB kit for around $40) and dual channel RAM will help in CPU and GPU tasks - as the GPU on the 3000G uses system RAM as VRAM. 

[--SID--]

Athlon 3000G only has 4 PCI-e lanes for the upper PCI-e slot (and 4 lanes for the upper M2 slot). From the chipset there are 4 lanes for the bottom PCI-e slot so a a PCI-e card that needs 8 lanes is useless with a Athlon 3000G.

so, what is the best choice for my athlon 3000g? ... NVME ssd?, it will work with my 3000g?.

 

pc store told me to use NVME SSD in my b450m i need new cpu ryzen 2000 at least, is that true?.

 

I DONT WANT TO BOTHER YOU GUYS, but i dont understant nothing of new terminology, hahaha, there is self teaching guide to study what the fuck is going on with my ryzen 3000g?

 

Thank you.

since i dont play games, more ram slots to dual channel , matters?

Isn't new terminology, PCIe has been around since 2003. AMD doesn't actually say how many PCIe lanes the 3000G has on their spec page, so you'd have to hunt down videos or reviews of it and hope they address it .

They might have assumed you had a dGPU installed. The manual doesn't specifically mention anything like that so it's unclear as well. 

 

I would either get the SSD and try it, or depending on budget/country you may just be able to get a cheap 4000/5000G chip which should have the full PCIe lanes. A 5600G is around $100 USD right now, that's a 6c/12t chip with the full 24 PCIe lanes (PCIe 3.0 only, x16 to GPU slot, x4 for CPU M.2 or another PCIe slot device, x4 to chipset - which can also feed other M.2 slots in addition to all your USB ports and such). Would be a drop-in upgrade on your board with the appropriate BIOS update. Here it is on the CPU Support list, needs BIOS version F61:

They are talking about the M.2 connector, that the M.2 will not support any PCIe SSD, because of lack of PCIe lanes in athlon 3000g.

If you use PCIe x4 -> M.2 key M adapter, on the PCIe x16 port, it will work with one SSD and at 32Gbps speed so full PCIe 3.0 x4 

asmedia asm1182e - that's a PCIe 2.0 x1 PCIe switch, it would work (no need for PCIe bifurcation support),  but I don't recommend, the speed will be afoul. I ran SSD like that on PCI e2.0 x1 (you get like 350MB/s). Now I use ASM2824 PCIe switch, with four M.2 ports, on my sandy bridge machine.
