When a card is keyed for A and E that would make me assume that it would only be able to provide PCIe x1. Regardless of that, the P11F part of the link product provides 2 PCIe x1 slots, so no, this would not get you up to x2 2.0, but rather, allow you to hook up two PCIe x1 cards to the one M.2 connector.

Moderator angerthosenear Posted November 20, 2013 Moderator Share Posted November 20, 2013 I wonder if you could SLI in this case - if they are considered separate ports. Would be something really neat to test. Quote Link to comment Share on other sites More sharing options...
Tech Inferno Fan Posted November 25, 2013 Share Posted November 25, 2013 Anybody wanting to investigate NGFF M.2 eGPU solutions should be aware that the vendors can wire through either SATA III or pci-e 2.0. Only way to find out would be to probe the system with the NGFF M.2 SSD installed to see what architecture is used. The lack of standards is not making it easy for us.REF: Understanding M.2 NGFF SSD Standardization (Or The Lack Of) | The SSD Review 1 Quote Link to comment Share on other sites More sharing options...
NBRsuuxxx Posted December 22, 2013 Share Posted December 22, 2013 I tried a bunch of 2013 drivers and with them my framerate is literally divided by 7 compared to a year old driver. My egpu is a Sapphire 5770 running at 1x. So I'm thinking either the driver is made primarily for the latest cards and they didn't try it on 5xxx or they messed with pci-e bandwidth on purpose or something's wrong on my side. At one time I got sick of reinstalling the drivers back and forth... 1 Quote Link to comment Share on other sites More sharing options...
jot23 Posted December 23, 2013 Share Posted December 23, 2013 Hi! Nit sure if you saw that, but I've tested HD6850 eGPU at x1 bandwidth. Drivers used were 13.9. No severe slowdowns caused by drivers, I think. You could check out my Crysis 3 benchmarks (FPS logs) in the main topic.Since 5770 and 6850 are based on the same old architecture, I think the same drivers apply to them, so the performance loss shuold be comparable. But the performance I've got is quite as expected from such eGPU setup. Quote Link to comment Share on other sites More sharing options...
allstone Posted June 28, 2014 Share Posted June 28, 2014 I have read that key B+M at least is supposed to support up to 4x connection (url), and i.e. using P14S-P14FP (M.2 to PCIe X2 Edge Extender Board) adapter we could also get 4x PCI express. I maybe would be willing to try similar adapters.. but I am still not sure if its better to remove mPCIe wireless card and connect eGPU into that slot (then I would need to buy ngff m.2 -> mPCIe adapter to use wireless) OR leave wireless in its place and get the extender board from NGFF m.2 to PCI express to connect the eGPU. As y510p SLI is still good enough for all the games, I am not in a hurry to try that, but rather slowly gathering information and seeing whats happening in this area.

Headcrash Posted August 25, 2014 Share Posted August 25, 2014 Hi,I just wanted to know if somebody already tried or is going to try out to connect a PCI-Express GPU via M.2 NGFF Slot.I found this adapter (P14S-P14FP (M.2 to PCIe X2 Edge Extender Board)) but i dont know if it works with the eGPU Setup. M.2 supports PCIe x4 so it should be faster than mPCIe and Expresscard right?Thanks Quote Link to comment Share on other sites More sharing options...
trollinteemo Posted August 25, 2014 Share Posted August 25, 2014 Yes it is theoretically possible. However it would share many of mPCIe's problems such as mounting. However I suggest not to use bplus' adapter it wastes the bandwith of m.2, the protocol and many laptops support full x16 throuput from m.2 sockets. If you want to wait I could build you a kit of my egpu for m.2 connectivity. forum Quote Link to comment Share on other sites More sharing options...
Headcrash Posted August 26, 2014 Share Posted August 26, 2014 Are you sure with the support of 16x?On wiki it says m.2 supports only up to x4. I am interested in an m.2 egpu kit but it depends on the price and i don't need an case for it.Whats the mounting matter with mpcie? Do you just mean the effort of plugging and unplugging while half of the laptop is took apart? I havent tried an eGPU setup yet so i havent any expierences with that.

trollinteemo Posted August 26, 2014 Share Posted August 26, 2014 Yeh sorry, was thinking of MXM. My big issue with using mpcie and m.2 is that every time you want to use an egpu you have to remove the bottom cover. If you are considering using a laptop as a desktop and just leaving it there, then m.2 is fine i just suggest getting one of the cooling pads that has a hole in the middle for cord management. If you have soldering experience you can rewire the mpcie or m.2 to external ports you dont use (i did one of the display ports and a usb 2 since my laptop had usb3) it makes portability much more feasable and keeps the setup neater.

sutton101 Posted October 20, 2014 Share Posted October 20, 2014 Am looking to setup an egpu on a HP elitebook 820 and would really like some help, am aware I am reposting some of this stuff, so will be last time. The 820 has two M.2 ports, one for 'flask cache' / ssd the other for wwan and was wondering if it is possible it tell if either is pcie wired. @Tech Inferno Fan suggested trying wlan card in M.2 ports to see of it was registered, but have tried and unless there is something I a missing, or miss understanding, it will not fit, let alone the pins line up. 820 ports - mpcie, 'flash cache' M.2 and wwan(?) M.2 (sorry about picture quality) Also playing round in HWinfo64 and noted second pcie port with slot implemented, could it be M.2? or something else? The second thing, is trying to get a M.2 setup even worth it from a performance point of view? If my understand in correct a pcie M.2 will offer an 8Gbs x2.2 link, which will allow optimus for internal display, but not compression, however the link will still get better performance than 4Gbs + c, am I correct in this thinking? Lastly does anyone know how the i5-4300u will affect performance, will it bottle neck cards like 660ti/570/760 making something like a 750ti a better option?

In addition it's listed as a x1 width link, not x2 as you desire. I'm 95% sure that you have a SATA NGFF.M2 slot, which unfortunately makes it unsable for eGPU purposes. Which only then leads your mPCIe2 wifi slot which can be used to host a 4Gbps+c link using a NVidia card. 1 Quote Link to comment Share on other sites More sharing options...

So there is a high probability that it would work. If you end up having a slot that is not A. I can make adapters for M B and E. I have the m.2 spec for my m.2 daughterboard so it wouldn't be too much trouble to make an x4 cable. Though I'd have to force output into multiple cables for use on pe4c, I'm developing one with minidp but its in the pipeline for after I mass produce my main board.

Problem with the clevo laptops is that they already have performance comparable to a desktop so why try to make a external system. T We need a MSI Gs30 like laptop, small, light, quad core, socketed cpu, intel iris or GTX 850 ish gpu onboard and a free M.2 type M slot. Haven't found more laptops that support the M.2 Type we need, hope CES brings more but getting actual specs from internal connectors seems to be hard.

CBabs Posted February 26, 2015 Share Posted February 26, 2015 Found this thread and it seems to be the only thing going with any information on M.2 as an eGPU solution. What I am planning is to hook up the new i5 NUC (NUC5i5RYH) to BPlus' 4x PCIe adapter and am wondering if there are any obvious problems with this before I spend money. The NUC uses a M-Keyed M.2 Slot according to it's Tech sheet. The point of this is going to be to make a super small form factor gaming rig with a 970 or 980.

I also found this I´m looking for a new laptop and I´m on a budget (as always) so I was looking for the L540. Turns out a few new Haswell laptops are using M.2 ports instead of mpcie, so it´s time to get this going! What I´m confused with is that yoybuy already sells exp gdc with M.2 cable (they say themselves that it can use M.2 Key A for egpu purposes) but has someone already realised it? Another question is I already have a Exp Gdc beast and i have a spare mpcie to hdmi cable. A friend of mine said he could, if I buy the L540, put out the Wifi M.2 card and crack out the Wifi element and solder the M.2 Key board to the hdmi cable. Would that settup work? I guess if I ask herocloud, they would ship me that cable anyways but it takes ages to ship and you know, just for a cable? And am I assuming right that it if at the key B(?) port a WWAN card key B male is connected, it is using pcie and if at the same port a ssd card with B+M male is connected, it is using msata (like saying at M.2 NGFF SSD Compatibility List | My Digital Discount) ? Correct me if I´m wrong, its superconfusing! Quote Link to comment Share on other sites More sharing options...
L10n Posted March 30, 2015 Share Posted March 30, 2015 I think that the EXP GDC only is capable of using PCIe x2. Make sure, you get a laptop with M keyed NGFF. You could solder a cable but do you know which pins you have to connect?If you just wonder how you could get your EXP GDC back working, use this:P15S-P15FOr something else that does the same: Converting NGFF to mPCIe.The NGFF to PCIe x4 adapter I found, really is capable of doing x4 3.0 Speeds.http://www.amazon.de/Express-PCI-E-Female-Adapter-Converter/dp/B00OQ1Y5E6And it is the same adapter also available in US (just look at the numbers on the board):http://www.amazon.com/WBTUO-LM-141X-V1-0-Drive-Adapter-Desktop/dp/B00UKWWARY/ref=sr_1_15?ie=UTF8&qid=1427736012&sr=8-15&keywords=pcie+ngff+x4 Quote Link to comment Share on other sites More sharing options...
