hey everyone 

 

after weeks i waited for this adlink mxm to pciex16 adapter (https://de.aliexpress.com/item/1005003809556859.html) to arrive from aliexpress i finaly can make a review and detailed test to see how this things working.... actually someone did already i mod like this for his Clevo P751TM1 but many question was not answered...as you can read this thread https://www.techpowerup.com/forums/threads/failed-to-use-desktop-vga-with-laptop-egpu.292790/page-2

 

What bothered me at first was that the cable was a bit too long...it's a bit hard but is still easy to bend, but you should still be careful...

the next thing you definitely need is a separated heatsink because otherwise the cable has no space to come out on gpu side....and also you can only put one screw in but its enough for now...first pics

The only gpus for testing i have are nvidia gtx 970 windforce-amd readon r7 370 and gtx 560 ti

and the psu i found is from Be quiet! Straight Power BQT E8-CM-480W...

 

as i know from the P751TM1 guy is that the internal screen will not work because there is no intel gpu 

but i fixed this problem with this display controller https://www.amazon.de/dp/B06WVMPWHP?psc=1&ref=ppx_yo2ov_dt_b_product_details

 

after plugging in everything i pressed the power and its started normal without any problem...the gpu adapter

also powers itself immediately with the psu so its started perfectly into bios first..bios shows unknown GPU 

but you can still see the vbios version...after booting to windows 10 its automatically started to install the drivers for the 970

 

i could also install the nvidia drivers without any problem but I was surprised that I didn't need an inf mod 

like i needed on 980m 965m 970m long time ago with a modded heatsink...

time spy gived me a score 2713 so you rly get the full x16 speed with this adapter 😄

 

i did some basic test like restart,power on off,some stress tests to see how the adapter acts but its rly rly working amazing

like a normal mxm gpu so i will not putting my mobile 1070 back in...alrdy searching for a 2070/360 lets see...

 

but i also wanted to know if the older gpus and also the amd will work..so i put the readon r7 370 in and its worked also perfect 😄

but now in bios i cant even see the vbios version anymore so everything is unknown with the amd gpu but also on benchmarks 

you getting the full speed out..i could install the latest amd drivers without problems...

 

the old gtx 560ti worked also well...drivers also installed perfectly...

 

but I don't understand why it doesn't need an if mod and the amd graphics cards work but nevermind

some screens from gpuz https://imgur.com/a/0Bw2f6n

 

after all i am rly happy with this adapter...so i dont need the expensive mxm mobile cards anymore..know i can put any gpu i want and even intel gpu i think....will sell the 1070 mxm and stick with 970 for know before i buy the new one...techicaly i can go up to 4090 in future but lets see how the adapter goes...will send some more pics later and mybe i will buy one more adapter as replacement

 

if anyone has question i am here to answer them 😉

Good job!

 

You don't need an inf mod because it behaves exactly the same as desktop GPU's do. You only need inf mods for MXM because they work a bit different with the Device ID's and such. (my speculation)

 

Now you just need to figure out a way how to make it hot-plug =D

 

Having an adapter permanently stuck to your PC is kinda shitty. You could use some external connector for the PCI-E lanes and then have a hotswap system for your PC.

 

When in need just plug in couple cables and have an eGPU ready! But this needs some serious consideration. I tried once with 2 HDMI connectors and the latest HDMI cable (HDMI 2.1a) and while it worked it gave me PCI-E corrected WHEA errors like crazy because the wires I used were not the same length.

 

It was for PCI-E 3.0 4x. For 8x you would need 4HDMI connectors xD I think so atleast.

Weird thing is that even amd gpu works, just tested readon rx 7900 from a friend and works 💪...

well the adapter doesn't bother me that much...I extended the psu cable so it doesn't stand on the table...also at least the gpu isn't that loud anymore so but I am planning a enclosure like from the egpus...let's see how it goes 😀

That's also to be expected. No reason for AMD GPU's not to work. Good job!

I haven't disconnected the GPU fan yet because I've heard the system needs it to boot,

but I'm not sure yet otherwise the gpu fan also goes full speed when the cpu fan is also full 😞

Try disconnecting it. Maybe there is some custom software to put the fan speeds manually?

today i disconnected the gpu fan ,it booted well and worked great buuuut when the cpu was @100% for around 1min the pc shuts down sadly...

the temps are ok of course after connecting the fan everything is back normal that means the ec controller needs the fan for a reason....

also i can controll the fan speed only from the 970 😄 .....also clevo controll center shows me the 970.....
