Issue with USB risers
-
Yup tried swapping parts and got the same exact issue on both rigs, however when I plug them directly on the motherboard they work like a charm. I had some old fashioned risers from ModDIY the 30cm ones but never worked so I sent them back. By never worked I mean no screen or anything. Was 30cm too long? I may potentially consider reordering powered risers that are flat if this does not seem to work.
I really don’t see what could be causing it because when I pushed all 3 side by side together as I said directly on the board, although it was smoking hot (I think I burnt my finger when I accidentally grabbed it when I was talking to a buddy). Is it possible if the cable is slightly taught that it could be pulling on the riser card and/or the PCI-E X1 card causing my issues? I have 12" cables (30cm) currently and they seem kind of taught. -
Did you get anywhere with these? I was looking at bringing in some of these for a couple of new rigs I’m building, I also spoke to them about bringing in 500 - 1000 to become a UK disto for them, but your post is making me very sceptical about them.
The look like a good idea, and would make the cabling a lot tidier, but if they don’t work then a total waste of money, I might just make some of the old style ones I have longer (replace the cable) as I don’t have any issue other than cost of the damm things running 3 connected together to get the card spacing right.

Well my next theory is that the cable is too taught and the vibrations are pulling it slightly out of the board, So I ordered 6 18" USB 3.0 cables to replace the 12" cables and some sugru that should be here tuesday or wednesday. So I will let you know. But no one has answered if the cable is taught could the vibrations from the fans be causing the card to slightly pull causing the system to lock up?
-
Just a thought, I saw in a listing on eBay that the cables are custom made - this may mean they are not wired the same as an ‘off-the-shelf’ cable, its worth double checking anyway… ???

I can’t really see this being the issue TBH, fans are balanced and they don’t cause that much vibration. It might be worth testing one with a card carefully positioned so that they are not taught and see what happens, the guy I was talking to said he had spent a long time looking for a reliable supplier and hinted that he hold sold plenty of them.[quote author=CloudScrypt link=topic=7322.msg56732#msg56732 date=1391385837]

I have seen the same comment in a couple of places, but without having one to hand to look at, poke with a meter I couldn’t pass commentUM

Many of them are poorly or incorrectly made - seems everyone and their grandmother are trying to make these cables for a quick buck in the mining boom. I make them myself, as I don’t trust anyone else to do it correctly ;)

How do you make them yourself? Also have you heard anything about the Magic Growing risers? I mean they work it’s just a question of how long they last, they boot up fine, screen is fine, then after a period of a few minutes to 20 minutes the system just locks up -
Issues are still continuing I have a video I will post later from youtube of me trying it out and then seeing it lock up

Here it is a video of it locking up

Now I had another thought even though I tested it on just one GPU… Do I need to increase the latency on the PCI bus possibly? -
I sent them back after all… I tried EVERYTHING on the BIOS with same results. So I ordered 12 PCI-E X1 -> X16 risers from [url=http://litecoinminingparts.com/]http://litecoinminingparts.com/[/url] hopefully they should be here next week. Hopefully these new powered risers will do well with my Gigabyte Z77X-UP7 and ASUS GPUs. I could not resolve lock up issues. So USB risers are a no go thus far. On to X1->X16 flat powered risers…
