It would work as long as you have a SLI capable chipset.

That might be interesting to test, actually.....

It doesn't suck ! I gets twice the FPS of whachamacallit's PCI 8400GS, that means I can run Crysis at 50FPS maxed out on an Atom 230 !

Seriously, though, good is relative. If anyone does this to the HD4870, he's a certified nut, but somewhere along the lines of the 8500GT and below ? That sure has applications.

Mussels · Jun 25, 2009

oh yeah, i mean, whats to stop me using a PCI-E 1x slot with an 8500 for Physx, for example? 10 minutes with a hacksaw, thats what.

mlee49 · Jun 25, 2009

3D06:
1x

16x

Yukikaze · Jun 26, 2009

Thanks, mlee, can you try and run a game or two with it taped down to PCI-E x1 ? Crysis should be interesting to see.

mlee49 · Jun 26, 2009

Yuk,

Dont have crysis but I could do Aquamark or another 3DMark run. 05 would be good since that was the era of the 8600.

Nice table of PCI-e x16 pinouts: http://pinouts.ru/Slots/pci_express_pinout.shtml
Yukikaze, why did you slice off the whole finger length except for lane 1? Wouldnt it be better to dremel out the single lane required to "jump" the plastic slot on the mainboard, leaving a 15 lane GPU? Goodness knows if a 15 lane GPU would work. Or a wider slot, leaving a 12 lane GPU? While you dont need it now, it might come in useful at a later date.

REQUEST: Could someone tape their GPU and try a 12 lane (not 16, not 8) setup and see if it works. If it does, could you try taping just ONE lane, and lane, and see if it works? I cant do the experiement because I'm on AGP.

If taping just one lane works, then there is no need to slice the whole finger off, but just "notch" where the socket is. The would be great to turn a 16 lane into a 15 lane, that is compatible with x8 socket, or x4 socket (depending on where you put the notch).

So are you wanting to try just the 12th pin taped over? Can you use a pic of the gfx card and show me what you want? I'd be willing to try it

Mussels · Jun 26, 2009

oh, dont use 3dmarks. they barely take a hit from the lower PCI-E lanes, while games take far more of a hit. I learned that myself with my crossfire setup. (and someone pointing this out to me)

mlee49 · Jun 26, 2009

So Street Fighter 4 benchmark ok? Last Remnant benchmark?

SF4 16x:

1x:

LR 16x:

LR1x:

For both:

mlee49 · Jun 27, 2009

benchmarks updated!

I want to run this as a Physics card next! I'll try that and get back to ya's!

HA! I need a Physx benchmark ASAP!:

MONEY!

EDIT: Running at 1x!!

With PhysX: 2162
Without PhysX 1368
Difference: 794

i think he modded the card because it is much cheaper than the motherboard. what would you rather destroy a cheap graphics card or an expensive motherboard.

Interesting mod. I think it was done out of desperation.

Far out!

I would never do this. I wonder how long the card will continue to live. I'd be worried about an electrical short destroying all the hardware attached to the MB.

you are not modifying the power pins that are in the first part of the pci-e slot. the second part is the pci-e data lanes that are grouped in 1x 4x 8x and 16x with this mod all you are doing is limiting the amount of pci-e lanes that the card can use from 16x to 1x. this mod should also work with 1x 4x and 8x pci-e lanes.

thebeephaha · Jun 28, 2009

I modded an 8600GT to 8x for a server motherboard. Worked great.

Taz100420 · Jul 5, 2009

Would this work on a 9500GT? I have it sittin around and I use my 8600GTS over the 9500GT. And would it work to use the 8600GTS in the X16 spot and 9500GT in the X1 for Physics?

It *should* work with any PCI-E card. But killing/castrating a 9500GT is a bit of a shame, IMHO.

Oh I wont cut the card lol Id just notch my X1 slot
I basically got the 9500GT for free :rockout:

In theory you could put 4 notches in the GPU, to have a 12 lane GPU, compatible with x1, x4, x8 and x16 slots!

a big

for the link to the pci express info ,i love having pinouts for anything to do with pc's

again

cobular · Jul 30, 2009

They do this!

Just thought I'd let you all know there is a motherboard out there filling the ITX need for fitting a graphics card but not able to support a x16 slot that uses something similar the "notching approach". It has a full sized PCIe x16 slot physically but is only pinned out to a x4 slot. Its the J&W MINIX 780G-SP128MB if you find a top down pic (like the one you can hopefully see below) you can see the pins stop after x4.

Mussels · Jul 30, 2009

the minix is old news by now, but still one hell of a HTPC mobo.
