pcie 1x to 16x riser cable

[manikyath]

so.. before people scream "bad idea"..

purely for experimental purposes

 

I have a mobo with a pentium silver, and only a pcie 1x slot.

I also have a GT640 sitting on the shelf.

 

i'm looking for a riser cable that'll do the whole voodoo of making the GPU think its in a 16x slot, but can plug into a 1x slot.

 

the general idea is it should be plug&play, it should allow me to install nvidia drivers, and it should allow me to use the GPU like normal.

it's mostly an experiment of finding out how much of a limit not being able to get a dedicated GPU on the pentium silver platform is, and how much of a limit running a gpu on pcie 1x is.

Past having the cable "work", i have zero expectations of performance.

 

my issue is, i have no idea where to find such a cable, and find one that will give me some sort of certainty that it'll even work. I dont really have a budget in mind, but i'd prefer something not astronomiclly expensive, and something that wont take a century to ship here.

 

so... TLDR, i want something that fills this gap:

 

GT640 (or any low-power GPU) => ??? => pcie 1x slot => working with windows 10.

Does it actually need to have a x16 link? Most all gpu's will work fine on a 1x link.

 

 

Id just get one ofthose mining calbes like these  Something like this https://www.amazon.com/Rebbic-VER009S-2-Pack-Riser-Interface/dp/B077N89ZBH/ref=sr_1_7?s=pc&ie=UTF8&qid=1527193181&sr=1-7&keywords=pcie+riser&dpID=51HU5HwRo8L&preST=_SY300_QL70_&dpSrc=srch

These adaptors are generally for mining, so a local mining group might be a place to find it.

dont nvidia cards need to be on 16x in order for the geforce driver to recognise the card?

 

EDIT: 8x.. math, it exists.

I think there are some miner adapters that you can use to do that

nope, 8x is just for sli. I have ran geoforce cards at 1x just fine.

digging out the back of the 1x slot as we speak, will report back with pics if it happens

yeah they don't require more than 1x  to install properly. I wouldn't recommend trying to game like that, but it works just fine - functionally-speaking.

pentium silver, in case you dont follow up on intel's new even more stupily complex naming scheme, there's supposedly a lack fo 16x slot for a reason

fair enough... I haven't used a Penitum CPU since the Pentium 4 days. They just don't make 'em like they used to

tbh.. for the ~€110i paid for the board..

not a bad pick.

everything about this feels wrong

[Electronics Wizardy]

but does it work? No one said its gonna be pretty.

well.. i have a display output.. and about 20 liters of sweat on my forehead

 

EDIT: it's downloading nividia drivers trough windows update

@Electronics Wizardy @Kalm_Traveler1

i am surprised..

actually hit ~95% GPU usage

 

time to toss some games on there!

[manikyath]

tried some rocket league, it's playable.. doesnt make me any better at the game tho
