M.2 to pci-e x16?

[Deuxez]

So i recently got a Lenovo thinkpad L440 and i first thought it had 2 mini pci slots on the motherboard but later found out its an M.2 port, is that true? And if it is a M.2 port are there any adapters that goes from M.2 to a pci-e x16 or a normal pci? or do i need to use the wifi card slot? It should work since the M.2 is much faster than the mini pci? The laptop got an intergrated HD 4600 that i want to replace with a bit more powerful card. The card is an Gigabyte GV-RX80L512DE (ATI Radeon X800 XL VPU). My other question is that this Radeon X800 card doesnt require an additional power cord and therefor takes energy directly from the pci, but will that work if i have an adapter from the M.2/mini pci? or do i need to use an gpu that needs an additional power cord. Hopefully could you understand my english, and i really hope that this is possible

the dedicated card is even worse

M.2 will not power a graphics card because it's not designed that way. Also the maximum number of lanes available for an M.2 card is 4, not 16.

 

In this case the M.2 slot is only useful as a data line. And while I have my reservations that the maximum bandwidth speed is going to be 4 lanes of PCIe 1.x, which severely bottlenecks modern cards, it might not be bad on an older card like the X800.

I got an 1050ti and a hd7850 sapphire, and those are more powerful. can i use those if i use the mini pci to pci x16 adapter? And use the 1050ti with just power from the pci?

How about getting a new motherboard.

Actually, Linus did a video on this and the performance difference was far from being drastic.

Testing fewer PCIe lanes on earlier cards or later cards?

Its a laptop, not Desktop. Cant just change it.

Will it work with a 1050ti on a mini pci to pci x16 adapter? And will it get enough power from the pci or do i need an extra Power supply?

No it's an adapter that attaches to your m.2 NVME slot so it must be m.2 NVME not m.2 S3. He used newer cards, I believe they were 10/10ti series.

Depending on the game at 1080p, PCIe 1.x x4 speeds will reduce the performance of a higher end GeForce 10 series card quite substantially. And it's that speed because the X800 isn't going to talk over a PCIe bus at anything other than the version it was rated for. What I'm arguing in my post is that it's probably not really a big deal for an older card because that won't require as much bandwidth.

 

However that's also assuming the M.2 slot was keyed for x4 lanes. It may have been keyed for x2.

 

It's probably not going to matter anyway since the X800 is a woefully outdated card.

I believe you'd need an extra PSU from what I remember. Any cheap PSU will do for 30$ USD or so, it'll never reach a high enough load to genuinely worry for failure.

I don't believe that's true, skip to 3:33 for the benchmarks. The "beast" is the product in question that allows you to connect a GPU to your M.2 NVME slot. There are very minor differences between a plain 1080 in a desktop and a 1080 connected via the m.2 slot.

In that setup the M.2 slot is running at PCI Express version 3. The Radeon X800 can only speak at PCI Express version 1.x. I'm using the performance loss of a GTX 1080 using PCI Express 1.x because that's what the X800 is going to be talking at.

You'd probably see LESS performance difference as you step down the ladder since 1x is a lower bandwidth. Doesn't really make sense that the perf loss would be higher when the bandwidth is already lower. Also, OP said they have a 1050ti and an HD7850 in addition to the X800.

I don't think my point is clear here.

1. The Radeon X800 uses PCIe 1.0
2. M.2 has a maximum of four lanes, therefore, a maximum of PCIe 1.x x4 bandwidth is available to the X800
3. I was using the GTX 1080 performance loss using PCIe 1.x x4 to gauge how badly the performance loss would be on the X800
4. At which point I realize this wouldn't really matter so much because this is an older card which wouldn't require that much bandwidth anyway.

Points 2-4 can be concluded from my original post:

So... I don't know what you're trying to argue here other than you're agreeing with what I'm saying and you think I'm not saying it in the manner you want me to.

i found this thing on ebay but i dont think it will fit the ports i have on my laptop. Do you guys know if it i will?  

 

[markr54632]

The compatibility of the gpu adapters you are looking at is horrible. It is also worth mentioning Lenovo locks down their bios tight, even wifi cards have to be on the Lenovo whitelist to work. Even if it fits most likely it is not going to work without flashing a custom bios. 

 

Iirc in that video they had to try a few laptops before they found one that works.

[Deuxez]

 anyone try to find a adapter to pci x16 that will fit in this type of port?
