why are these cables so expensive? Is it any different from this $4 cable? (http://cgi.ebay.com/PCI-E-1X-Riser-Card-PCI-Express-Ribbon-Extender-Cable-/180673151583?pt=LH_DefaultDomain_0&hash=item2a10f5825f) and any idea why it costs $2.7 extra to cut the side of a pci-e extender?

I believe it's the same cable, but Cablesaurus ships from the US, while that Ebay seller ships from China.  With Cablesaurus you wait 2 or 3 days (assuming you're also in the US), with the other seller you wait 2 or 3 weeks.  If you're depending on having those cables to add more mining capacity, getting them quickly is of utmost importance.

and any idea why it costs $2.7 extra to cut the side of a pci-e extender?

Because there are lazy people who will pay that much to have someone else do it for them.    If you're not one of those people, you can save $2.7 per cable.

ok, makes sense.

is it complicated to cut it?

Not particularly: http://blog.zorinaq.com/?e=53

I use a hacksaw, and then a knife to cut out the remaining plastic bit that's inevitably still in the slot afterwards.

Plug 'n play ... and the guy obviously knows what he's doing.

So using 2 power supplies with these is a no go?

Hey guys I just got my 1x->16x extender and I can't get my comp to pick up the 3rd card. I've tried with and without dummy plug, still no go. Can anyone post up a picture of using a 1x slot with the extender to the vid card? My buddy tried everything even messing with bios and nothing seem to get the video card detected.

Comp stats:

-Win 7 64bit
-Already running 2- 5870, using extender to plug in a third card
-Mother board is Asus P5k Pro with both 16x slots already used and using the extender on a 1x slot.


Any help would be much appreciated!

Try running one of the known-good cards on a known-good slot through the extender.  If that doesn't work, either there's a problem with the extender, or you may need to short the presence-detect pins as shown here: http://blog.zorinaq.com/?e=42

I've tried different cards and switched them around and all the cards are in good working order. I'll look into that link you sent me thanks Chris. More help please! I have 400mhash that isn't being utilized, the sky will fall soon if I don't get it working asap lol.

Didn't Inaba say that there are issues with grounding/frying parts? How would you hook up another power supply so that both would turn on when you turned the computer on? There are only guides on how to jump start it...

Just checked out that article and I see there are 2 pins that must be shorted if the motherboard doesn't allow down pluging. What is it I'm supposed to use to short it with?

Ahh..I reread everything...
I'll just buy the Lian Li adapter from FrozenCPU..that should solve my problem!

Alright, time to order some of these modified cables

[Cablesaurus]

Shorting the presence detect pins should correct this issue, one would bridge pins A1 & B17 as in this picture:

A 24-ga wire should slide right into place without forcing.

This is something that seems to effect a small percentage of motherboards, while on the majority it won't be necessary.

[pokermon919]

Thanks Cable, I'll be giving it a try first thing in the morning tomorrow.

Will the 1x extender fit underneath a GPU? For example my rig uses an MSI 790 gd70, with 4 gpus. I'd like to add a fifth using the pci 1x slot, but I'm not sure if I'll need to also extend the gpu that covers that slot.

[Inaba]

Depends on the fan shroud on your GPU.  Most shrouds are too low to fit an extender in it.  Some aftermarket (and stock) coolers have some space between the HS and the board, you can run the extender up through the HS and then over to where you need it.

As far as the jumper goes for presence detect, all my motherboards required it, so I soldered the wire onto the extender. I will try to get a picture of it later today.

[lastobelus]

ok, seems like I'll need to use a dremel tool.

Now the question is power: I'm already using a cpu->pci and 2x molex -> pci.

I have only 2 more molex connectors on the PSU (which has plenty of watts -- 1250)

Do any of these have a chance of working, and which is likely to be better:

1. Split one of the pci connectors
2. Supply half of each of two molex->pcie adapters from a single molex line, using these adapters in two different gpus
3. Split the CPU line (cpu is a sempron 145, and I'm running headless so cpu usage is around 5%. so draw on the cpu line should be pretty low currently)
