Hypothetical Adaptor question

Postby Choma on Wed Nov 09, 2011 2:35 pm

This is purely for research purposes - just something i started wondering about...
So, hypothetically speaking - Someone has an old Desktop PC that doesn't have PCIe,
& they want a Super-Recent-Awesome-NameBrand-GPU without upgrading the whole PC.
Which only has AGP & PCI. I know an adaptor from AGP to PCIe is fairly hard (or impossible) to do.

Now, all of this, although insane, sounded quite interesting to me!

SO i looked at various external solutions:
like the ViDock - http://www.villageinstruments.com/tiki- ... age=ViDock
Which unfortunately would require an internal PCI card that gives an ExpressCard port to the desktop.

And of course some internal ones:
Like using http://pinouts.ru to manually wire up a card (Dangerous & UnReliable Sounding)
OR using adaptors like http://www.epn-online.com/page/42574/pc ... ridge.html
However i am unsure if the above adaptor is for PCIe(16x).
So just in case: an adaptor from PCI to PCIe(1x) and into that plug a PCIe(1x) to PCIe(16x) adaptor?
So like this (PCI->PCIe1->PCIe16):

Straight onto the motherboard goes this adaptor:
http://intrl.startech.com/Cards-Adapter ... d~PCI1PEX1


And into the previous adaptor goes this adaptor:
http://intrl.startech.com/Cards-Adapter ... ~PEX1TO162


Thus allowing a PCI-E card to be plugged into a PCI slot.

NOTE: i know that it would require custom housing & power - so dont worry bout that...

but what about bandwidth requirements?
Maybe it would require 2xPCI slots adapted into 2xPCIe1 - which are then wired together to the 1xPCIe16 - thus providing more bandwidth? is any of this even possible???

Certainly worth investigating re: a set of PCI slots maybe, but I suspect you'd still have bus speed/bandwidth issues..

By the time you've bought a bunch of parts to work around it, trouble is, you've probably spent enough time & money that it's actually cheaper just to go buy new ram/cpu/mobo.

Yeah, i figured it would be cost prohibitive to do it exactly that way.
but if the adapter method could work?
then one could possibly jury rig using cheaply bought or harvested components...

Something else stumbled upon - I'm guessing it would be ludicrously expensive :(

That board connects to a pc via PCIe(1x) & has a PCIe(16x) (among other things)
Wonder if it has problems with bandwidth aswell?

That's an interesting mind exercise.. my gut feel is the high bandwidth would make PCI-E graphics cards very sensitive to timing and electrical interference issues so any of these adapters would be VERY touch and go and sensitive, if they worked at all.

older PCs with PCI-E slots are close to landfill status so replacing the motherboard would lead to a lot less hassles.

Surely the adapter is pretty pointless as although you will be able to use a pci-e graphics card with this adapter in this old PC, The new graphics card would be restricted by the pci bus speed of the motherboard.
Me thinks you should ditch the motherboard, RAM, CPU and rebuild.

Agreed - I had an AMD quad with mainboard death that was only a couple of years old.. it took a lot of phone calls and a drive across melbourne to find the last of what was for a relatively new CPU type.. (AMD AM2) - in the end the only board still around supported AM2/AM3, so even the fact it existed was a piece of luck.

Here's the thing though... improvements on stuff are so fast moving that by the time I had it up and running again, it was only a few weeks before I was considering an 8 core that was a lot quieter and higher MHz - I ended up giving the quad to a friend under 3 months of fixing it.
