MP 1,1-5,1 Syba I/O Crest SI-PEX40129 usage?

[mikas]

Speedwise no difference. You will loose one slot though, maybe two, depending on your graphics card dimensions.

Please make sure you read the upgrade sticky and PCIe sticky too, if you haven't already (the first posts of them at least).

Got it. Thank you for the info. Much appreciated.

I'm real late to this party, but I'm looking at getting the Syba card for my 5,1.
No difference running the video card in slot 2?
(It looks like it's the better solution all around.)

No difference, the Video card run's real great. By the way, I have slightly upgraded my Syba card with a little resistor that slows down the fan a little bit and makes the complete package a lot less noisy. If you have a Dremel tool to your disposal, I really recommend this mod for the Syba card. It was a fun little weekend Dremel job that works well.

You could consider the HighPoint SSD7101A-1; for me it gives better results

Hi, I have a 5.1 cMP, 2x3.5 Ghz 12-core, 128 GB RAM, AMD Radeon VII on PCIe slot #1.
Above the GPU card, in PCIe slot #2 I have a Syba I/O CREST SI-PEX40129 card with two NVMe 970 EVOPlus 1TB (latest firmware).
I see that others are able to reach a read and write speed even at 2500 Mb/s, while in my case I can't reach over 1500 Mb/s.
How can I solve this limitation keeping the same Syba card?
Thanks in advance!

 

[DigitaLife]

I have a cMP 2010 5,1 and I ordered a SI-PEX40129 card to solve the 1500MB/s limitation. I already have a Samsung SM951 MZ-HPV5120 SSD mounted on a PCIE 3.0 card running Catalina.

The SI-PEX40129 card supports dual SSDs. I would like to have installed a different OS on each, so I can perform the OpenCore upgrades easy.

Do you think it will be possible to boot from a specific SSD mounted on the PCIE card? Also, can I mix the type of SSD used, based on the compatibility guide we have on forums? I was thinking to use a Samsung 970 Pro, next to SM951.

Way back when I purchased the SM591 (and paid a lot of money), the only solution to have an external bootable drive was the AHCI type. From what I see, with the latest 144.0.0.0 firmware, we can use other SSDs, which are way more affordable.

Thanks for your help.

Hi,
in an other thread you confirm this: "My NVMe's are a lot faster than my Sata SSD (Mojave), that is why I run Big Sur and Windows on them.My NVMe's are a lot faster than my Sata SSD (Mojave), that is why I run Big Sur and Windows on them" and you showed this results (see the picture attached).
Could you please tell me how you achieved these speeds with the Syba card and NVMe 970 EVOPlus disks?
I can't understand why I don't go over 1500 MB/s!

You can achieve this speed with the syba in SLOT 1 OR 2 only, in slot 3 or 4 you will only have 1500Mb/s approx.

I know, but my Syba card is already in slot 2!
I also tried to put it in slot 1 but the maximum speed remains the same (max 1500 Mb/s).
Please help me!

 

[DigitaLife]

I installed the Syba card in slot 2 but had to add a round foam sticker to the video card, to have clearance for the RX580. Is the white foam between the GPU fans, into screenshot. Thank you IKEA for these foam stickers ?

You can see the Sonnet Allegro above the Syba. I prefer that card, instead of a regular USB3 card. I can use a USB-C to USB3 connector, if I want to attach an USB3 drive. The Allegro works perfectly in Catalina, very happy with the purchase of these two upgrades.

The EVO Plus results are definitely not spectacular on the Write side, I should've purchased the Pro. Can anyone post the AmorphousDiskMark results with their Pro? Here are mines, I hope the Writes are as bad for Pro also.

View attachment 889447

I have the similar configuration, Syba + NVMe 970 EVOPlus (slot 2) and Radeon VII (slot 1) but, as you can see in the picture attached, the maximum speed for me is only 1400/1500 Mb/s (W/R).
Any suggest to solve this issue?
Thanks in advance!

 

[TECK]

You have the latest firmware on your EVOs?

Certainly! 2B2QEXM7 (See attached image).
Please TECK, my only hope is on your competence!
Tell me what I can try to do!
Thank you very much in advance!

I run the I/O Crest dual PCIe card in my 5.1 with two AHCI blades. I am very happy with the card, the cooling is excellent and it is very fast.

@TECK
If you want the max speed out of your I/O Crest, you will have to put the card in PCIe slot #1 and move your GPU card to slot 2&3, - loosing one slot in the process...

AlexMaximus, isn't slot 1 & 2 identical 16x ?

 

[Flocarino]

Yes, they are 16X identical slots both of them (1 and 2)

 

[basslik]

I seen mentioned to place in slot 1 and to loose a slot didn't sound right to me. Although I do wonder how the heat dissipation is working with the fans being almost completely blocked.

One reason to put the GPU in slot 2 is if it is more than two slots wide. But then putting it in slot 2 would make slot 3 AND slot 4 unusable. In that case I might try finding a x16 riser that could fit under the GPU in slot 1 to give access to slot 2. I don't know if such risers exist.

 

[flygbuss]

I have a 5,1 with two of these cards, one in slot 1 and the second in slot 2 and they perform identically.
As @joevt mentioned there are other reasons to put the gpu in slot 2.
I use the 5,1 most of the time headless as a server, so I don’t mind having the gpu not in one of the x16 slots.

 

[joevt]

I remember having a boot issue with some GPU / SATA controller card combination. Moving the GPU to slot 2 helped in that case. I think it was a Boot Camp problem. Now I don't use SATA controllers in my PCIe slots.

According to your signature you use a RX580 (Pulse I suppose) which is 2slots high.

If you install the GPU in slot 1 and SYBA in slot 2 , as you mentioned, both GPU fans are almost completely blocked and you may even have to put a foam/plastic spacer between them to avoid rattling.

If you install the SYBA in slot 1 and the RX580 in slot 2, you'll lose slot3 (obviously), but the advantage is that e.g. a USB card (being way smaller than the full length SYBA), will only obstruct (partially) the airflow to one of the GPU fans.

 

[basslik]

Yeah I have the RX in slot 1 and the SYBA in slot 2. It seems to be running fine and I don't see any heating issues quite yet. Although I don't game and only for recording so the fan only spins on boot up and doesn't run at all that I've noticed. I read somewhere it's designed to only run when needed ?

Thank you all for your input.

 

[KeesMacPro]

Correct , at ~50 degrees the fans start spinning.

 

[basslik]

KeesMacPro, right on, good to know.​

Noticed I have the display port plastic cover from the RX placed as a backup spacer LOL

 

[KeesMacPro]

I made a passively cooled version last year.
Bought a heatsink, distance bolts, a piece of copper, Noctua heatpads and Phobya thermal glue.
PCI fan is controlled by the blade Temp ; it never goes over ~38Celsius.

WOW that looks really nice. That's a SYBA ?

Hi,

Wondering if anyone can help me out - I have the SYBA SI-PEX40129 controller installed in my MacPro -

Model: 4,1 updated to 5,1 firmware
OS: Catalina 10.15.7

The card is installed in slot 1, x16.
Im using two 500GB Samsung 970 EVOs
Firmware of both drives is 2B2QEXE7

When I look at the system report, "Hardware > NVMExpress", both drives have a link speed of 8.0 GT/s, but one drive has a link width of x1 and the other x4.

When I run AmorphousDiskMark separately on both drives, I get different speeds. Is this to be expected? I would have thought both drives have the exact same speed? Is it possible my card is defective, or is there some additional configuration Im missing?
