How do we test memories for Mac Pro 6,1

Posted by Yunyan Qi on

Mac Pro 6,1 can work with max 128GB DDR3 ECC memories. We sold lots of those memories. We do extensive testing before we ship each set. It's not practical to test every set using a real Mac Pro. Mac Pro is expensive and shouldn't be used as testing device too often. So what shall we do? Actually, instead of testing memories on real Mac Pro, we test it on a PC board. The most compatible motherboard for such memories is Intel x79 boards. We build a PC on such motherboard and run Mac OS on it. Once Mac OS can...

What's the difference between Titan Ridge and Alpine Ridge

Posted by Bill Dong on

TITAN RIDGE VS ALPINE RIDGE Alpine Ridge: The Alpine Ridge uses Intel chipset DSL6540, and the video links are negotiated at DisplayPort 1.2 speeds and sent down over either HDMI 1.4 or Thunderbolt 3.  The manual states to officially allow for a maximum resolution of 4K 24Hz over the HDMI port, but the Thunderbolt ports allow for up to 4K 60Hz (a single 5K Thunderbolt display can allegedly work on the Alpine Ridge as well).  Only bus power is provided with the Alpine Ridge unfortunately and the card is supplied with a total of 38W, which allows you to power...

Can LG 5k Thunderbolt Display fully work with Titian Ridge card?

Posted by Bill Dong on

We know that LG 5k display can work with flashed titan ridge card, without camera or sound support. I did some experiment on finding an easy way to enable camera and sound. There is an interesting cable like this: https://www.amazon.com/Panghuhu88-External-Mainboard-Internal-Extension/dp/B07T87XY77?ie=UTF8&fbclid=IwAR1yA1_xJPpgk-ooLLGPgR4X4p4DZJt6llmTyfe1c6xONuN7ySTB7uuYzrE&ref_=pe_2640190_232748420_TE_item%29#ace-2342880709 It can connect usb header of your card in to one of Mac Pro's external USB slot. I did two experiments on this cable: 1) I tried to connect my wifi PCIe adapter to Mac Pro's external usb slot using this cable so that bluetooth may work. But it burned my wifi card. 2) I tried to connect titan ridge's...

How do we test Airport wifi bluetooth cards for Mac Pro 4,1 5,1

Posted by Bill Dong on

We sell wifi & bluetooth cards, for both bluetooth 4.0 and 4.2. It's not easy to test those cards to see if they work or not. For a full installation, you need to connect four anntentas on this card and it's not a simple job since the anntena connectors are very small it may take long time to finish connectiing them. Also, those anntena connectors are pretty fragile so you cannot keep connecting and disconnecting many times. Fortunately we don't need to connect anntenas before we see if this card work or not. Without anntenas connected, we still can determine...
