ASUS Z-87 Pro Floating between detecting SSD

I just finished building a new computer with a ASUS Z-87 Pro motherboard and I have an OCZ Vertex 3.

Sometimes when I boot up it detects the SSD and other times it doesn't.

I've swapped the SATA cord.

And sometimes when windows logs in I have the default windows background and the screen will just turn the light blue color of the background and I have to force restart it.

And now it seems to go in between detecting the DVD drive as well.

Which SSD is this? If it's a Sandforce 1200 controller this is a known issue. The SF1200 controller is non-compliant with SATA spec. Intel tightened up signal tolerance on Z87, so the drive will not detect at all times. There is no long-term fix for this, you will need to use a compliant SSD. The newer SSDs are fine

Also, due to the tolerance margins of this chipset make sure you use the SATA cables that came with the board - some third party or generic SATA cabes will also cause non-detection at POST.

If you are wondering why, all Intel Z87 ports are SATA6, the signal margins to support this mean that crosstalk and noise must be kept within spec. Non-compliant cables and controllers therefore have issue.

If this is a Vertex 3 and not a Vertex 2 what is the firmware version of the drive? The Vertex 3 should have no issues when used with the Z-87 Pro when connected with the proper SATA cable as Raja wrote.

I will be doing a BIOS update and a firmware update for the OCZ Vertex 3 when I have time after work. I'll let you guys know what happens.

It never fails to detect the hard drive I have in there too but it does rarely fail to detect the DVD drive.

Another issue is that when it does detect the SSD is also sometimes does a blue screen right after the windows logo that only shows for less than a second then the computer restarts. Generally after this happen the SSD is not detected after the restart then I have to restart it again and it's usually good to go.

When it does boot up and get through windows there doesn't seem to be issues.


EDIT: Well I bought it from a friend and now I see that Speccy is saying it's a vertex2. If I return it and get the new Samsung 840 pro there shouldn't be any issues?

Picked this one as solution because it was that fact that I was using a Vertex 2 that I thought was a vertex 3. I returned the vertex 2 and put a Samsung 840 Pro in and there have been no issues what so ever.

Thanks everyone!

just saw this and i am waiting on the exact same motherboard as this with this ssd - SanDisk SDSSDP-128G-G25 128GB SATA 6GB/s 2.5 Inch Internal SSD

This was only £65 on amazon so now i'm worried that i'll have the same problem?!

The SDSSDP-128G-G25 is a SATA 6Gb/s SSD so will not be using the incompatible SandForce controller. The SSD should work fine with the ASUS Z-87 Pro.
