DX58SO Smackover Pcie 2.0 ports not working

On the lastest BIOS 5600.

I have an ATI 7790 connected to the primary PCIE 16x video port.

The secondary PCIE 16x port is only showing up at 2.5 GT/s for my Nvidia GT240.

The top port which is supposed to be a PCIE 2.0 4x port will not show up as 5 GT/s for my Asmedia 1061 SATA III controller.

If I take out the secondary video card and put the controller into that port it will then show up at 5 GT/s.

Yes I am aware that I will only get 5GT/s instead of 6GT/s of a real sata III port.

Yes I am aware that I lose some 4k read/writes on my ssd but gain in sequential read/writes.

This board also refuses to boot when theres a usb thumb drive connected ( i've tried about 5 different brands ) set up to be bootable or not. Interesting the 1TB external USB drive seems to work just fine. This leads me to believe its a power related issue.

This board has never let me sleep/hibernate and wake correctly if overclocked. I can only go up to 150 from the stock 135 to still be able to wake. Any higher overclocking results in it not being able to wake up.

This board used to randomly lose connection on the LAN port, at first from waking up, but that was fixed from a bios update, but would still lose connection on the ethernet after a while on windows 7, I had to mess with alot of different drivers and might have solved the problem later on. I haven't seen the issue in windows 8.

Anyone had success using the PCIE 4x slot at 5 GT/s ? The board technical notes seem to suggest its a PCIE 2.0 4x port while the two 1x ports are PCIE 1.0a.

Main page description shows : http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-board-dx58so.html Intel® Desktop Board DX58SO

Expansion capabilities
  • One PCI Conventional* bus add-in card connectors (SMBus routed to PCI Conventional bus add-in card connector)
  • One primary PCI Express* 2.0 x16 (electrical x16) bus add-in card connector
  • One secondary PCI Express 2.0 x16 (electrical x16) bus add-in card connector
  • One PCI Express* 1.0a x16 (electrical x4) bus add-in card connector

However available configurations link shows :

Expansion OptionsPCI Support 1PCIe x1 Gen 2.x 2PCIe x4 Gen 2.x 1PCIe x8 Gen 2.x 0PCIe x16 Gen 2.x 2

Which implies all parts are Gen 2 ( PCIE 2.0 )

And Technical Produc Specifications PDF shows:

• Two PCI Express 2.0 x16 bus add-in card connectors

• One PCI Express 2.0 x4 bus add-in card connector

• Two PCI Express 1.1 x1 bus add-in card connectors

Which imples the x4 slot is a PCIE 2.0 ( Gen 2 ) but isn't operating as a Gen 2.

So which is it, is the PCIE x4 slot above the video card a Gen 1 or a Gen 2 slot ?

Hello Vo_Danh, I am afraid to say that this motherboard has been out of support since June 2013 http://www.intel.com/support/motherboards/desktop/sb/CS-034322.htm http://www.intel.com/support/motherboards/desktop/sb/CS-034322.htm Intel no longer provides interactive support for these products via telephone, e-mail or chat. Technical support is only available through the http://www.intel.com/p/en_US/support support site. http://www.intel.com/p/en_US/support/highlights/dsktpboards/dx58so http://www.intel.com/p/en_US/support/highlights/dsktpboards/dx58so

This behavior could be related to a lack of power or to compatibility. I would recommend you to test each video card separately in order to find which is causing the conflicts

You can also try rolling back to the previous BIOS version and check the behavior of the system.

Look with the video card manufacture if they can a new firmware updated you can try.
