List of motherboard that require shorting pin A1 B17 for pci-e 1x to work.

[multi#lord]

Shouldn't this thread be transformed into a wiki (and organized by platform/socket)? Probably be little easier to find a specific board/cpu/manufacturer, just an idea  .

EVGA P55 Micro:

-x1 needs shorting, and powered riser; unstable when booting into Win 7 64 (using a 6850 or a 7970)
-Legacy PCI slot with riser to PCIE x16 and a powered riser makes system unstable and locks, won't reach Win 7 64 login.

Wiki, Well I'm trying to update OP with new board contribution.

Are you sure you need powered extender for, what 2-3 cards ?  It is recommended when going 5 gpu and above.

If I use a video card on the x1 slot, it apparently won't be detected unless it is a powered riser (while other slots are populated with gpus), I do not know why that is. I use a powered riser on the PCI slot just to be cautious, given that it provides lower wattage at the slot.

I am going to be testing out my pcie x 1 slot with an adapter & a card.

Would any type of overclocking while using the pcie x 1 slot, fry the pcie x 1 slot and/or the gfx card?

What are you guy's thoughts?

I am taking extreme caution before preceding.

Of course, this question is for the slot being shorted and not shorted.

I tested running only a 7970 on x1 of my P55 micro, I was able to raise from stock 925 MHz up to 1200 MHz without any issues. Although, needless to say, once you start increasing clock, wattage will increase, it should not be an issue if the card is receiving enough power (and good cooling).

Ok, fantastic, ty. I was worried as stated here in the thread, few come back saying this or that fried.

Are you using a powered riser? or a combo of x1 to x16 followed by a x16 to x16 with a molex power adapter?

The ASRock Z75 Pro3 1155 does not require short pinning of the PCIe x 1 slot.

[multi#lord]

The ASRock Z75 Pro3 1155 does not require short pinning of the PCIe x 1 slot, but I do not receive the correct mhash/s.

Hmmm... I would get the same hash rates using a 7970 on either a x1 or x16. Although, I did need to reconfigure (such as workload, size, cpu or gpu ram, bfi, etc) the 7970 when it was newly installed in the x1 slot, but I'm assuming you already did that?  PCIE bus clock probably isn't the problem, you have more than enough bandwidth to do mining on x1 pcie.

Does the slot on the board have to be shorted or can I sort the pins on the end of the cable?

I figured the shorting is why my board doesn't see a card (Gigabyte 965P-DQ6)? I'll post more specific results tonight.

Either or should work. Also if you insert the jumper on pcie x1 slot, as you slide an adapter in the slot, the wire gets secured.

[runlinux]

No luck... must be a bad cable. I have some new ones coming Monday. Will post back again later.

The Foxconn Destroyer needs both x1 and x16 slots to be shorted to use extenders (x1-x16 or x1-x1).

[runlinux]

ah ha! helps if you read the manual... installing a card in the second pci x16 slot disables the 3 x1 slots... ungh...

No shorting needed on a GA-965P-DQ6 !

ASUS P5Q DELUXE also needs this fix

[Ilikeham]

Asus F1A75-V EVO does also

How do you guys usually do the short?  Just cut it out of the ribbon and then connect them with a wire?

You see the picture in the OP ? This red thing is a wire,

Use a solid core cat5 braid and insert in behind the pin of either the extender or the slot itself.

How do I keep it from making contact with the other nearby pins?

Look at it a little longer,
Every pin are isolated in their own little compartment, stick the wire in there. (On the motherboard side, not gpu)

Okay, shorted successfully using 4 mini staples soldered to two cut molex cable wires and successfully activated 2x PCIe 1x slots with risers on an eVGA 680i motherboard.  Yay!  If you have mini staples they're perfect for this, although once you stick the card in it bends the normal wire and messes up the slot permanently for use without the short.  Not really a big deal though.

Solid core 24 AWG , solderinh ?

Solid core 24 AWG , solderinh ?

Problem?  The rig seems happy enough.  It was just a dab to get it to stick to the staple.
