PCI-E 1x for GPU

[AhmedFromKSA]

Hey guys

 

I have a mining rig that works perfectly right now and i want to add an extra GPU.

the problem is that the motherboard on that rig only has one PCI-E 1X slot free left. So i was wondering if it is

possible to use something like this ( 1X to 16X riser ) as a solution and if so will it effect my mining performance?

It probably won't even recognize the card. I think motherboards only check for graphics cards if they are plugged into a full length 16x slot. 

 

I could be wrong though. 

[AroundWayOtherThe]

I think it would run, just the bandwidth would be severely limited, and mining performance would drop as a result... Feel free to correct me on that though

[ExDreamer]

Even you use that,it would only use 1x bandwidth so it would badly affect gpu performance.

 there is an easy way to jump start the motherboard and make it recognize it as a GPU

[Woodypc]

NO, Just NO! :huh:

[AhmedFromKSA]

I'm going to buy the raiser and try it out with my current card. then ill come back to you guys in a week or two lol

crossfire in a z77 board means you use two x8 slots, or some do 3 4x slots so it might work.

I meant a full 16x length slot that a graphics card can fit in. Not a 1x slot or a standard PCI slot. 

 

I know some slots only run at half or quarter bandwidth.

works on folding, i dont see why not

[Levent]

yup it should work since you really have no use for bandwidth while mining

[DjArtifact]

I've used risers like this for mining and it works fine.

[MG2R]

Should work perfectly. PCIe is designed to not be bound by the amount of lanes you allocate. If you allocate less lanes, you get less bandwidth, but the card will not stop functioning.

 

For mining, you don't need a lot of bandwidth, so using your card in a 1x slot shouldn't be a problem.

doesnt seem bad at x1  at 2.0

if u have x1 at 3.0 it would be great

btw sometimes u dont need a riser

the end of the x1 x4 x8 lanes are  cut out at the end of the lane so u can put any card you want

if it isnt u can just dremel the end of the lane

there is a less risky way 

cut the end of the pci slot with a knife heated with lighter so you can cut it like a cake

any hashing rate decrease ? Edited July 6, 2013 by AhmedFromKSA

a 2 slot card cant fit in the 1x slot since the slot under it has the current graphics card so thats why i need a raiser

there next to no difference between pcie 1.1, 16x, pcie 2.0 8x and pcie3.0 4x i dont know what yours is but if its anything like these i mentioned you will get a performance hit (not sure how much cus i dont mine/fold yet).

id say try it :D let us know..

[elazar55]

For mining it will work fabulously, many many miners use risers for this. Good luck getting one though kinda sold out in a lot of places so many people buying risers lol.

[DjArtifact]

The decrease is marginal, I was running a 5970 off of it so a single card will need even less bandwidth.

performance stays the same?

[Whaler_99]

Performance should be the same - this is very common for Folding. The main thing that you need from x16 over x1 is transfer rates - so playing a game where you are sending and receiving a LOT of data, this can make a difference. But I know for folding, typically the card gets "loaded" with the work and then Folds... there is not a lot of bandwidth transfer and almost zero difference in performance.

 

Now bitmining, I don't do this, but the principle is the same, but I believe because of the hases on the work, there is more transfer of information, but honestly, it isn't a lot, and therefore you are not overly affected. The actually processing power of the card is not affected.

i dont think the computer would even register it as a graphics card

[AMICLG]

Most motherboards that are made to handle 3+ graphic cards have PLX controllers so it's not in x4.

i commented on that before

there is a way to short the motherboard into recognizing it as a graphics card

 

like what is shown here
