I have the 1M long version and notice no problems. I even have the USB cables bundled together and coiled on themselves a few times, trying to antagonize something. Seems to be fine, I imagine USB 3.0 is pretty well shielded. Plus isn't pci-e 1x ~400mb/s, or about the same as usb 3.0?

That e-bay seller is turning out to be a slimeball though. He seems to keep increasing the price, but still hasn't shipped the cables I ordered days ago at a lower price. A real bummer, only place to get them Sad

Hi Mate what PCI-E to USB3.0 part were you referring too?? I can only find something like this (http://www.ebay.com.au/itm/Combo-PCI-E-Card-Adapter-2-Ports-USB-3-0-eSATA-3-0-SATA-3-0-20-Pin-extender-/190898812868?pt=AU_Components&hash=item2c7274b7c4)

Cheers

Ahh ignore that i missed the link right there at the top of this page!

Kk cool!

Are we talking about the same seller? http://www.ebay.com/itm/PCI-e-express-1X-to-16x-Riser-Extender-Card-with-molex-power-30CMS-USB-3-0-Cable-/321272676674?pt=LH_DefaultDomain_0&hash=item4acd580142#ht_2368wt_1188

They are expensive on there... but what I did was went directly to the site http://eshop.sintech.cn/index.php?main_page=advanced_search_result&search_in_description=1&keyword=PCI-e+express+1X+to+1X%2F16x+Ris Not sure if its any different in terms of how soon something will be shipped, but it's a little cheaper even with the shipping costs.

Just out of curiosity, now that were dealing with USB 3.0, is there any way to put a USB hub/splitter in between and run several PCIE cards off of one 1x? I'm probably thinking way out there! But the more cards you can get on a single Mobo, the better right? *lets assume power is unlimited Wink

No, it's not acual USB signalling going thru the cable, it's still a PCI-e 1x lane signals.

$30 now! He's raising his prices by the day!

I contacted the seller about getting more of them, and was told that they wouldn't ship out for at least a week.

I'm about to purchase four of those PCIe USB3.0 Riser/extenders. Two options.. one comes with 30cm of usb cable while the other comes with 100cm's. I know as soon as you get distance involved, heat can occur. But if these things are powered and simply data is sent along the USB.... can I get the 100cm one with no issues?

Thanks

The extra power (powered riser) is connected to the PCB connecting to your graphics card, so the card isn't powered from the mobo though the usb cable, it's used only for signalling.
Signal degredation over the distance may be a problem though, but I wouldn't expect them to be seeling a 100cm variant for a PCI-e riser if that was a problem.
Get one of each and test? can always get a shorter usb 3.0 cable from a local store if it doesn't work properly with the 100cm cable.

Make sure your rig temperature is lower then 70c and keep flammable object 10 meters away and your done..

Why remove anti-static bags?

AFAIK they are not insulator...

Flashed on metal coatings and all that.

"Worried about fire and using such a flammable material as WOOD to house your rigs?"

I stopped reading right there. Many computer cases are plastic and combust at lower temperatures than wood. I assumed everything else said was equally wrong.

Well, you don't use cases of any kind for mining rigs.

Open air "space frame" rigs are the Jizzle, Schizzle!

Try keeping 7 cards cool in any kind of a cse!

LOL!

An exercise in futility!

And wrongo, Boyo!

Most dry wood will ignite at the famous Farhenhite 451 but ABS, from which most cases are now constructed require high temp to flame up.

Heat and fire! Right now, my two rigs are simply layed out under a WOODEN table (with those anti-static bags below the mobo). The mobo's are raised slightly for air circulation. All GPU's are plugged directly into the mobo, no risers are being used at this time. The table/rigs are being fed cold, dry, canadian winter air... which is perfect. All GPU's run well under 75 degree's, dependning on the outside air temp.

Whatever You do in future, please get rid of anti-static bags under powered boards...

Yea, i'm extremely hesitant to do watercooling simply on price alone, but it might be something i'll look into for the summer.

powered PCI-E riser question: Is there any difference in powered PCI-e risers? Whether its a 16x-16x or 1x-16x? On ebay they range from $5 to $100+. Just wondering if some get more power than others, or are they all the same?

They should all be the same. The only exception might be the USB 3.0 riser cables that I love (a lot better than the flat ribbon cables) I believe those risers need 5V in addition to 12V, where a normal riser only needs 12V. Another reason I like the USB3 ones, airflow...

You don't need to waste money on x16-x16 risers, but I would get x1-x16 risers so the card can lock into the riser. Trying to maneuver and route a 4" wide x16-x16 link riser cable is difficult and entirely pointless for mining.

Hey Everyone,

LostDutchman - HAHA yup, fully aware of my current wood situation. I need to get away from it. As of right now, i'm fairly confident that my two rigs are safe. But it's when you think that, you get caught.. hence why i'm trying to find different solutions.

Everyone has made some great points! I will not build anything outside. I'm interested in the water cooling, but isn't it expensive? Is it cost effective?

Thanks!

Again, based on my own experience, wateror liquid cooling is a large pain in the ass. We actually developed a system loosely based on liquid cooling but found it to be expensive, complicated and although it worked, was best suited to certain automotive applications, so although we had gone so far as to apply for a patent pending status, we have essentially dropped it.

Air cooling is the best we have found using a manifolding system to delliver cooled air from an aira conditioner to each rig.

My $.02.

Waterblocks pumping water to a radiator. Stick the rad outside if you really want to!

As for avoiding fires a $10 smoke alarm is an essential piece of kit!
