Syba Dual M.2 M-Key NVMe Ports to PCIe 3.0 x16 Bifurcation Riser Controller - Support Non-Bifurcation Motherboard (SI-PEX40129)

There are over two benefits to it, and it works perfectly. The read speed is 9 GB/s and the write speed is Using a Samsung 970 Pro NVM blade, 2 GB/s of write performance is possible. Lycom DT-300 was what I was previously using A PCIe 2 slot can only support 120, which is the limit. Spec of the Mac Pro is 0 (a top speed of The third part of the equation consists of It is lanes 0 and 1. Both the M and M pads are thermally bonded to the card. This model has two blades with a chip, an internal fan cooling unit (really quiet). It is an incredible upgrade for a machine that is ten years old.

So far, the support has been excellent and the product is excellent. The only issue is the small font size. Summary

I would give the movie At the end of the day, I'm happy with the product and I'd purchase it again from Amazon. I'd give it a five, but Amazon only allows whole numbers and I can't justify perfect. There was no need for me to worry about the issues because the manufacturer could easily resolve them. It was super responsive and helped me to be very happy with the product.

Installation - It is supposed to come with 4 screws, but they never arrived. The NVMe sticks will be attached with two NVMe screws to hold them into the mounts, while the other two will hold them in the mounts. These were on the packaging, as well as 1 screw which was way Due to the fact that the 4 screws required to remove the heat sink and shield were the same ones, I was able to steal two of those and use only two on the shield until I could obtain I was very pleased to see the manufacturer's prompt response to my question on screw size, and as a result they referred me to their Support department. Their Support department was great, and they replied quickly to my order, and shipped out the missing screws quickly. I don't think a better handling of a problem is possible. There was also a small screwdriver included so you don't have to get one during installation or find one once you get it. It's always a plus to have the option to do this. No action was required on my part for Windows 7 to pick up the card and load drivers. Those drives are not booted from, so I do not have any info on them. -Family -As discussed in the "Manual" that comes with the product, the "Manual" is not a manual and is merely a small piece of paper listing product features, System Requirements, and includes no operating instructions. You will not find any support instructions or URLs. In addition to not finding any documentation on the Support site for the screws the rep sent me to, I also did not find any other documents on the site. My expertise let me get through it fairly easily, but other people may find it more difficult. I totally understand not wanting to spend the money on a big manual, and I am totally cool with that, but at least provide a pdf on the site for your * Support of compatible systems Using an MSI x99s Gaming 9 AC with a 40 lane CPU, I am able to run my games well. In the beginning, when I was looking for a slot for this or comparing it to other slots, I was not confident that this would work in an x16 slot with only eight PCIE lanes. That is true, as I can now tell you. The only issue I can tell you is that, on my motherboard at least, when put into the slot with two groups of 8 lanes mapped to it, it locked up all 16 lanes. That meant that my card in another slot that used the other 8 lanes could not run. I had a x8 card in the slot previously, which did not force the issue. It had to be put in the slot that had the second eight lanes and only eight lanes mapped to it while the NVMe drive was placed in the 16 lane slot with a standard PCIE adapter. After that, it worked like a charm. It's recommended that you contact your MB manufacturer to get a diagram of how the PCIE lanes are switched to your MB slots. In addition to its x16 capability, an x16 slot does not necessarily have 16 lanes at work. In the final slot configuration, there is a Lycom PCIE NVME adapter with a Samsung 950 Pro in Slot 1. Front eight lanes (Uses. The Samsung Evo 870 M was used for all testing. The Samsung Magician software is used to manage two NVMe drives each containing 1TB. The first time I tested it was in a While the performance was slightly lower with this adapter, I doubt you would ever notice. After testing it with a 2 slot adapter, I then tested it with this product. Overall, this card is not a major concern for users, because they would be spending more on their setup than this card. It is not a factor, but I am sharing the information in the interests of being transparent. **In the Lycom adapter, the following settings are used **Sequential (MB/s) The read/write performance stats for this product with two drives are Random (IOPS) - Read 412,109 / Write 300,781By using drives in both slots - Sequential Reading 3490 / Writing 2420, Random (IOPS) - Reading 390,625 / writing.

In addition to using it with a Samsung 970 Pro NVME, I also purchased the card to get the maximum performance from the As a result of the gen 2 PCIe slots on the classic Mac Pro, an NVME blade installed in one of those slots can only reach 1500MB/sec. Combined with a 16x slot, this card can be used to create 4x gen 3 speeds from 8x gen 2. This card allowed me to reach over 2900MB/s with the same 970 Pro card when using a blade. The problem is that when it is installed with one blade, when copying large files, it will hang and then restart the Mac. It would have been possible to buy another SSD, but knowing it would be troublesome with just one led me to return it. There was just something about it I didn't trust. Furthermore, the standoff screws included with the NVME boards were the wrong size.

There was no sign of it in hight sierra. This is not true. There is no such place.

Upgraded to Mojave and it still does not see it, nor does it offer it as a boot drive. It's a complete waste of money at the moment, and it makes me a little EDIT

This was my fault. I had a problem with the There is a rod on the number one card that secures the back notch. My mistake was not realizing it was seated when it was on the ground. The mistake I made was that I assumed something I didn't. Basically, I pulled it out and put it in an x16 slot (I used to have a Kingston Predator AHCI blade drive, but I moved it to an x4 slot) and then I put this in there. The drive came up after a bit of fiddling, but when I rebooted it, no problem. The new Mojave installation was cloned there and rebooted as well. I use the Amorphous Diskmark program, and it shows it to be about 20-fold larger The Kingston is about 25X faster than the stock Sata 2 port, which is about 10X faster than the Kingston. I decided not to take the risk of the faster Samsung speed by using a Silicon Power nvme drive rather than risk the higher cost. Two can fit in the carrier, but not one. Italics are required.

The product I purchased was at a Mid-price range Having 4 PCIe 2 slots on a 2012 Mac Pro is pretty impressive. The port count is 0. There are only two 16x ports. Card # 2 is a single wide slot, so it works excellent with a slot like this one. There is a double-width slot in the Mac, but it has an AMD Radeon RX 580 installed in it. This means that this card blocks slot 3, only leaving a single slot for another slow. In addition, the NVMe blades get very hot, and right after a while, I noticed things on the screen that weren't there before that didn't get fixed, such as "artifacts" Following the removal of the card, the message will appear. As you can see from Black Magic's SSD benchmark, this card with two Samsung 2TB drives (4TB total) can reach write speeds of up to 2450 MB/sec and read speeds up to 2895 MB/sec, which is pretty impressive for a PCIe 2 bay. Although the card is designed to be used with PCIe 3, it nevertheless supports PCIe 2. If you increase it to 0, it should run twice as fast and at the same time not display the artifacts. This is how it works in the real world The internal SATA-based performance tests give a realistic picture of real-life performance I found that the two drives on the Mac's motherboard with direct slots performed more linearly and produced a better result. Usually a Virtual Machine runs in only 20 seconds on my SATA drives, but I sometimes use them for other things Two drives (in a three-driver The RAID0 configuration) it would boot up My suspicions are not that this issue is related to the controller, but rather it might be related to the older PCIe backplane that was not sufficiently powered. Due to circumstances beyond my control, I had to return the card and.
