Gigabyte Z97X-UD5H mobo + Intel SSD Drives - BIOS does not see the SSD drives.

Have a new Gigabyte Z97X-UD5H motherboard and Intel SSDSC2BF480H501 2500 series enterprise-level drives (OEM versions from NewEgg), and the BIOS won't see the Intel drives. I've upgraded the mobo BIOS to 10F (the latest), updated the Intel drives to the latest firmeware with the Intel Toolbox utility, rebooted, loaded the "optimized defaults", but no joy. I've swapped power cables, SATA cables, etc etc - still nothing. I have only my keyboard, mouse, DVD drive, USB hub, a single 8gb memory stick (the correct kind according to the Gigabyte site list) and a single monitor (installed on the onboard video currently). I have the network cable connected. No other peripherals are installed.

The PSU is a new 550w ThermalTake from BB, and the voltage is correct, and will power my older platter drives perfectly well. The board also report correct power in the BIOS screens.

If I put the Intel drives in another machine with an older ASUS mobo, they're recognized. As mentioned, while they were in that machine I ran the Intel Toobox and updated the drive to the latest firmware. The ASUS systems shows the discs in disk management, allows me to format them, etc etc.

Is there something obvious I'm missing? Or do I have a bad mobo, or incompatible components?

Check BIOS settings and make sure your SATA's RAID/ACHI is set for ACHI (or RAID if you are doing RAID) and your boot mode is UEFI
Andy MIT Systems ManagerCommented:
Have you tried the drives separately and in different sata ports? Just noticed the following on the board's spec page:


    1 x M.2 PCIe connector
    (Socket 3, M key, type 2242/2260/2280 SATA & PCIe SSD support)
    1 x SATA Express connector
    6 x SATA 6Gb/s connectors (SATA3 0~5)
    (M.2, SATA Express, and SATA3 4/5 connectors can only be used one at a time. The SATA3 4/5 connectors will become unavailable when an M.2 SSD is installed.)
    Support for RAID 0, RAID 1, RAID 5, and RAID 10

Marvell® 88SE9172 chip:

    2 x SATA 6Gb/s connectors (GSATA3 6~7)
    Support for RAID 0 and RAID 1

* Due to system limitation, Intel RAID and Marvell RAID can only use either one

It's possible a bios configuration or connection is disabling the connectors the SSD's are attched to. Aside from that not sure what else it would be outside of compatibility but you could contact Gigabyte support who may be able to provide more assistance.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
The SATA mode is ACHI (I'm not configuring a RAID at this point, but will in the future). I'm not sure exactly what you mean by "UEFI Boot Mode". When I boot the machine, it goes to my BIOS setup screen, and the top banner reads "GIGABYTE - UEFI DualBIOS". I don't see a "boot mode" setting anywhere. Can you give more details on how I'd do that?

I have tried each drive separately, and in all of the ports, including the ones controlled by the Marvell controller. The board does not detect them on any of the ports.

return the board for an RMA
NerdsOfTechTechnology ScientistCommented:
Sata power or boot mode may be preventing the recognition of the drives.

Try alternate psu or power to drive
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
Don't have an alternate PSU, so I can't do that right now, but I'll see what I can dig up.

I have all available power connections, with all available SATA ports (all combinations), and none of them work.

My only concern with a board RMA would be that my drives are not compatible. I've got a ticket in to Gigabyte support to determine if that's the case. If so, then I'll have to return the drives and get different ones.
NerdsOfTechTechnology ScientistCommented:
I guess another test would be to see if another SATA drive will be recognized.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
The board recognizes other SATA drives - it's running right now with a 500 GB WD platter drive - but it won't see the SSD drives. I don't have any other SSD drives to test it on, unfortunately.
NerdsOfTechTechnology ScientistCommented:
Try connecting the same cable and power connected to the platter drive? Same results?

If same, mb is suspected. Incompatibility?
best contact Gigabyte with this problem - they may have a newer bios update
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I did contact Gigabyte, but they have not responded. I ended up purchasing a Samsung SSD drive that was on their QVL, and the board immediately recognized it, and I was able to complete the process.

I did update the BIOS on the board, and updated the firmware on the drives. I also performed a low-level format on the drives, and that actually got the board to recognize the drive a few times, and I was able to install Windows. However, after installing Windows 10 on the drive, the machine again failed to recognize the drive. Can't have something that unreliable, so I am going to RMA the drives instead of the board.

Bottom line for me was - make sure the hardware is on the mobo's Qualified Vendor List. I realize others have had good luck with installing drives that aren't on that list, but for me, and for my needs, I'm going to stay on the straight-and-narrow!
it looks like the disks go the way the Ram did before

maybe the density, or format is different.  i wonder what difference there is , causing this problem
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I'm not sure. I contacted Intel, and they essentially said the disks comply with the current SSD standards, and if the mobo doesn't recognize them then the board/bios must not be compliant with those same standards. Gigabyte claims the board is compliant with current SSD standards, but then goes on to state they only certify their boards will work with discs/memory/cpu as defined in their Qualified Vendor List. Seems if the board is compliant, and the disc is compliant, then they should work together - but I'm here to tell you that ain't the case :)

I purchased the mobo + cpu + memory all together, and made sure the cpu and memory were on the same QVL for the mobo. So far, all is working, with the exception of a few display driver issues.
is Gigabyte willing to exchange the board for another one?
maybe it has a flaw somewhere, and that is the only test method i know
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
Not sure, but the gist of the conversation I had with their support staff was "we only guarantee that our boards will work with drives on the QVL". I could ask them, I suppose - but I don't think they'll do it.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
So another Gigabyte tech is apparently involved, and this guy said the board should recognize that drive. Not sure if they're going to RMA it or not at this point, but I've already got the Intel drives RMA'd, so it's kinda of a moot point.
i'm curious as what the result will be
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I'm thinking more and more it's incompatibility with specific Intel drives. BestBuy had Intel SSDs on sale today, and one was a 240 GB drive with this model number:


The Gigabyte QVL shows this 120 GB one as a match:


I figured what the heck - it's the same drive, just more capacity, so it has to work. I bought it, plugged it in ... and the BIOS would not recognize it. Plugged it into my machine with an Asus board (older chipset, believe it's an H61) and it saw the drive.
NerdsOfTechTechnology ScientistCommented:
Incompatibility may likely be the problem in this case.

An additional test with another sata, non-Intel, ssd drive (Kingston, Corsair, etc),  would further  solidify the hypothesis.

Or RMA board and cross your fingers the issue doesn't persist.

More shopping may save you more time than rolling the RMA dice.  

 Trying other SSDs may also be able to shed some light as to if the motherboard is the problem or not.
try to get the board swapped - seems like a flaw
also - check if there is another bios update  available
NerdsOfTechTechnology ScientistCommented:
Can the PSU sata power be an issue?recommendation before mb RMA : Purchase:
 another PSU
 a non Intel SSD)

Recommended procedure:

Try recognizing the non Intel ssd

Then, if no success, replace psu,  try Intel ssd.

Finally, if no success Replace m/b (RMA or new board)

Return all unused parts.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I have a Samsung SSD coming in on Monday, will try that. So far, no issues with the current Samsung drive so hopefully it's just a compatibility thing.

To date, the mobo has recognized my current Samsung drive (which was on the QVL list) and a Seagate SSD that I pulled from my wife's old, dead laptop (the Seagate drive was NOT on the QVL list). With one brief exception, the board has not recognized 4 different Intel drives.

The PSU is brand new - I know that doesn't really count for much, since new PSU's could be dead as well, but the PSU has no issue powering the Samsung and Seagate drive, so it would seem the issue is not with the PSU but rather the drives.

I already have an RMA number on the Intel drives, and they're going back today, and I'm returning the other two Intel drives to BB today.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I'm also going to push Gigabyte to RMA the board. I really cannot afford to be down any longer, but I also don't want to risk troubles down the road with a bad mobo.
that's what i also expect  would happen " troubles down the road "
NerdsOfTechTechnology ScientistCommented:
With the final ssd test confirming both that the non-Intel  SSD is recognizable and that the PSU sata cables are operational and functional, there is therefore, either

1.) a defect / problem with the motherboard; or,

2.) if there isn't a defect, a compatibility issue exists between the board and Intel SSDs.

 Let us know if the same problem exists with the replacement board.
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
Gigabyte has confirmed troubles with the board, so I'm going to send this one back. I've actually ordered another identical board (can't be down for a week with the back-and-forth), and this time I got the "black" edition of the board, which is supposedly "burned in" for 168 hours.

I think I'm also going to hang onto the Intel drives until I get the new board, since Gigabyte claims they should work. I'd much rather use those for my boot drive than the Samsung EVO I ended up with. I've RMA'd them already, but haven't shipped them back, and I've got about 10 days left before the RMA is void. I should know something by then.
David Johnson, CD, MVPOwnerCommented:
Personally I'd return a product that does not work with standard hardware. I want to mix and match hardware on demand or a whim.  This is why I use a PC not a MAC
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
Agreed, which is why I'm taking your original advice and returning that board. Gigabyte has said the Intel drives I had should be recognized, so hopefully the new board will do so and I'll be back on my way.
NerdsOfTechTechnology ScientistCommented:
Testing aside, replacing the board directly with another model sounds to be the optimal solution in this case.

It sounds like the Intel drive (incompatibility?) issue only affected that board so far.

Can't wait to hear the results from your new board test with Intel ssd's. Chances are it will work. I have doubts about the  rmd'd board and commend you on your instinct to replace the board  model.
i'm curious for the result
Scott McDaniel (Microsoft Access MVP - EE MVE )Infotrakker SoftwareAuthor Commented:
I received the new board and installed it over the weekend, but unfortunately the same result - the board refused to recognize the Intel drives, but it immediately picked up the Samsung drives I purchased. At this point, I'm putting it down to incompatibility with the board and drives.

I've sent the old board back for refund, and have done the same with the Intel drives. Never thought a mobo would be unable to recognize drives from a big-name company like Intel. Could kinda see it if they were off-brand stuff, but Intel drives?? Makes me wonder about Gigabyte boards in general. Shoulda stuck with ASUS like I've always done.
