Desperate for advice to overcome port shorting...

[gox1201]

As the title says, I'm pretty much pulling my hair out on one of my motherboards.

I have to short every port to run the GPU's from the 1x powered riser cables.

This in itself is a total P.I.T.A, but having finally overcome my tremor, and managing to short A1-B17 its all fine and dandy.

However, ive had several instances where my fans have dislodged a cable ever so slightly, and then it stops mining

or even more irritating, the cable erodes with time, and after about 2 weeks of mining has sufficiently degraded that I have to remake another cable etc.

I just DONT have the energy for this crap every 2-3 weeks.

So questions to those that know:
1) Any motherboard I can run 6 cards on that doesn't need port shorting? (motherboard that is available locally I mean ---> not asrock BTC boards)
2) Do the USB risers still require port shorting like the ribbon cable ones?
3) Any other suggestions?

Solution is simpler than you think. Short the pins on the riser itself, then you don't need to muck around with the slot on the board Solder the scoobie wire to the 2 points like this:

Easy as

Heh, there is no way I have the ability to solder that fine. I don't think I've soldered more than twice in my life truth be told. Will keep on looking

Practice on old electronics. I used cd roms to learn a few years back. If you the have precision for surgery, I'm sure it won't take you long.

I will be running 7 x cards (hopefully) only using USB risers, I will test this first hand and report my finding back here for everyone to read.

Will send you a whatsapp

Sorry for derayling but why does port shorting happen? I am just asking if maybe I should run into this because I am looking to buy risers still deciding between the usb and normal powered one

It's called a presence short. Some motherboards need it else they won't recognize all the GPU connected. You will need to short the USB ones as well, unless it has the short built in.

I'm running 7x cards in my rigs, and in Linux, all hashing, no presence shorts nothing. It comes down to the planing on what hardware you are gonna use to avoid issues such as these later on.

Some yes, not all, which is why... I went with Z77 Mpowers, with my risers I do not NEED to short. I've given a TON of info away in my for sale threads about what hardware I use in my setups, just from that you guys can simply copy my setup
[MENTION=23192]gox1201[/MENTION] bud, I suggest you seriously look at the Z77 Mpower or Z87 Mpower, they are pricey boards but it'll stop headaches such as these happening to you.

Let me know if you need more advice.

I run 6 per board by design, but those mpowers are double the price. For the 30 second solder job it was a no brainer for me to save that cash. Most of the time it's 2 or 3 risers that require the short...You can actually presence short every riser, it doesn't make a difference.
