DQ77MK MSATA Port SPEED ? 3 or 6Gb

Jump to solution

 

Hello,

Refering to : http://downloadmirror.intel.com/21340/eng/dq77mk_TechProdSpec02.pdf http://downloadmirror.intel.com/21340/eng/dq77mk_TechProdSpec02.pdf

On page 16 : it's told 6Gb port

Letter : X SATA 6.0 Gb/s connector (multiplexed with an mSATA port, routed to the PCI

Express Full-/Half-Mini Card slot) (gray)

On page 17 : for the same connector 3Gb

I bought a 6Gb SSD mSATA drive and it's detected as 3Gb under ESXi 5.1.

I have no hope, cause i think it's a bus limitation but if an intel Employee could give me a clue for the technical possibility by design.

And if so for a bios release...

TIA,

Hi,

recently I got the DQ77MK motherboard and I installed an intel 525 mSATA SSD (120G).

The newly installed drive is recognized under the operating system (Win7) and is fully functional,

 

however, I cannot see it in BIOS SATA management page, only in the boot options.

How can I make sure the SDD is running at it's designed port speed (6Gb/s)?

Thanks,

Dimitar

Pages 26-27 from the http://downloadmirror.intel.com/21340/eng/dq77mk_TechProdSpec04.pdf DQ77MK Technical Product Specification provide additional information. However, I will request a correction on this document since the information does not appear to be clear regarding the port speed.

You may try a third party tool such as http://www.piriform.com/speccy Speccy.

The MK board has PCH SATA Port 4 connected to the MUX supporting the mSATA and (Grey) SATA4 connectors. PCH SATA Port 4 is a SATA II 3.0 Mb/s port.

I verified this using CrystalDiskMark. On an 8 Series board (which has 6x SATA III 6.0Mb/s ports), a mSATA drive achieves R/W of 562.5/323.6. On the 7 Series board (which has 2x SATA III 6.0Mb/s ports and 4x SATA II 3.0Mb/s ports), a mSATA drive achieves R/W of (only) 281.0/186.2.

It is page 16 of the TPS that incorrectly states that this connector supports SATA III 6.0Gb/s.

Hope this helps,

Thanks for the answer but i didnt get it...i m talking about connecting an m sata ssd (sata 3 speed at 6gb/s) without sata cable directly on the mobo's slot.

That's *exactly* what I was talking about as well. I was detailing the physical connections (signal traces) that exist on the MK board itself. The SATA4 port comes out of the PCH component (the chipset) and goes into a MUX device that allows either the mSATA connector or the (grey) SATA4 connector to be utilized. You can see this in the board's logic diagram on page 17 of the Technical Product Specification.

Bottom line, the mSATA port on the MK board provides a SATA II 3.0Gb/s connection. This is why the measured performance was roughly half what I get from the mSATA port on my 8 Series (Z87) board, which provides has a SATA III 6.0Gb/s capability in the mSATA port.

For the best performance, you want to use a SSD connected to the (blue) SATA0 or SATA1 connectors on the board. If you have already purchased a mSATA drive and would like to get the most out of it, use an adapter like this: https://www.amazon.com/gp/product/B004YKJ5TE to connect the mSATA drive to the SATA0 or SATA1 connector.

Hope this helps,

No, your board and processor are simply too old for that. Its BIOS does not have support for NVMe boot included. In fact, it wasn't until the 5th gen processors (and boards with 9 Series chipsets) that support for NVMe Boot was enabled in the BIOS.

Sorry,
