Lord Lucifer Posted June 24, 2014 Share Posted June 24, 2014 Hi all, I'm new to the forum and am need of desperate help! I built a new 4k gaming PC, but can't seem to use my cards... I've tried to follow this: http://www.corsair.com/en-us/blog/2014/may/setting-up-ocp-on-the-ax1500i But not having any luck... I understand theres 2 cables for Corsair Link, I only have 1 connected (mini USB -> USB port on Motherboard) and perhaps thats the issue, but I can't work out where the digital cable goes... I'm desperate to get gaming @ 4k any help is appreciated... PS: Wasn't sure if this is a PSU issue or Link issue. If placed in the wrong place apologies.

Corsair Employees jonnyguru Posted June 24, 2014 Corsair Employees Share Posted June 24, 2014 First things first: You don't use both connectors. You use one or the other. So you're fine there. Second, how are you using your PCIe cables? Since X2 cards are essentially two-in-one solutions, it's suggested that you use two PCIe cables per card and not use the "pig tail" connector on the cables.

Cool, perhaps thats the issue then, it's defo the "pig tail" solution I'm using currently... Link to comment Share on other sites More sharing options...

jameyscott Posted June 25, 2014 Share Posted June 25, 2014 Mine whispers to me in the night.... "Jonny... you are a wonderful person... Smile and the whole world will smile with you....." First off.... LOL Seocnd.. When it comes to pig tail connectors, they definitely should not be used. I honestly wouldn't suggest anyone use them for any GPU. Some GPUs will be fine with it, but I think it is always better to have two cables going to your GPUs whenever possible because that actually allows you to safely overclock. Whereas, you might be putting too much load on one cable (Like you did with the R295x2!) and either it won't work, or it will melt through the sleeving on the cable.

Corsair Employees jonnyguru Posted June 25, 2014 Corsair Employees Share Posted June 25, 2014 The sleeving isn't going to melt off. The pins are the weakest link, they'll overheat and cause some discoloration and sometimes melting of the connetors. But the wires never get hot enough to melt anything. Pigtail connectors are fine for GPUs with a 6-pin and an 8-pin as those cards shouldn't be pulling anything more than 225W from the PCIe cables, but certainly not anything with a pair of 8-pin connectors.

jameyscott Posted June 25, 2014 Share Posted June 25, 2014 So, the pigtail connectors can actually supply the full 225w TDP? I was unaware of this. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted June 25, 2014 Corsair Employees Share Posted June 25, 2014 Actually, you have the potential to deliver another 75W through the PCIe slot. But power is going to take the path of least resistance. Link to comment Share on other sites More sharing options...
jameyscott Posted June 25, 2014 Share Posted June 25, 2014 More if you can control the PCI-E voltage like you can on the classified cards. :P Link to comment Share on other sites More sharing options...
