Thank you Computer Gods for your divine intervention and BIOS Settings

Posted on Updated on

I’ve been in IT for over 20 years now and in my time I’ve seen some crazy stuff like –

  • Grass growing in a Unisys Green Screen terminal that was sent in for repair by a Lumber yard
  • A Goofy screen saver on a IBM PS/2 running OS/2 kept bringing down Token Ring till we found it

But this friend is one of the more weird issues I’ve come across….

This all started last March 2012. I bought some more RAM and a pair of 2TB Hitachi HD’s for my Workstation 8 PC. I needed to expand my system and Newegg had a great deal on them. I imaged up my existing Windows 7 OS and pushed it down to the new HD. When the system booted I noticed that is was running very slow. I figured this to be an issue with the image process. So I decided to install from Windows 7 from scratch but I ran into various installation issues and slowness problems. I put my old Samsung HD back in my system and it booted fine. When I plugged the new Hitachi HD in the system as a second HD via SATA or USB the problems started again, basically it was decreased performance, programs not loading, and choppy video. I repeated these same steps with the 2nd Hitachi HD that I bought and it had the same issues.

A bit perplexed at this point I figure I have a pair of bad HD’s or bad HD BIOS. Newegg would not take back the HD’s, so I start working with Hitachi. I tried a firmware HD update, I RMA both HD’s and I still have the same issue. Hitachi sends me different model but slower HD and it works fine. So now I know there is something up with this model of HD.

I start working with Gigabyte – Same deal as Hitachi BIOS Update, RMA for a new System board Revision (Now I’m at a Rev 1.3) and I still have the same issue. I send an HD to Gigabyte in California and they cannot reproduce the problem. I’ll spare you all the details but trust me I try every combination I can think of. At this point I’m now at this for 5 Months, I still cannot use my new HD, and then I discover the following…

I put in a PCI (Not PCIe) VGA video card into my system and it works…

and then it hit me – “I wonder if this is some weird HDMI Video HD conflict problem”

I asked Gigabyte if disabling onboard HDMI video might help.

They were unsure but I try it anyway and sure enough I found the solution!

It was like the computer gods had finally shone down on me from above – halle-freaking-lujah…..

 

 

 

Here are the overall symptoms….

Windows 7 x64 Enterprise or Professional installer fails to load or complete the installation process

If the installation completes, mouse movements are choppy, the system locks up or will not boot

Attaching the Hitachi HD to a booted system via USB the system will start to exhibit performance issues.

Here is what I found out….

Any Combination of the following products will result in a failure…. Change any one out and it works!

1 x Gigabyte Z68XP-UD3 (Rev 1.0 and 1.3)

1 x Hitachi GST Deskstar 5K3000 HDS5C3020ALA632

1 x PCIe Video Card with HDMI Output (I tried the following card with the same Results – ZOTAC ZT-40604-10L GeForce GT 430 and EVGA – GeForce GT 610)

Here is the solution to making them work together….

BIOS under Advanced BIOS Settings – Change On Board VGA to ‘Enable if No Ext PEG’

This simple setting disabled the on board HDMI Video and resolved the conflicts with the products not working together.

Summary….

I got to meet some really talented engineers at Hitachi and Gigabyte. All were friendly and worked with me to solve my issue. One person Danny from Gigabyte was the most responsive and talented MoBo engineer I’ve meet. Even though in the end I found my own solution, I wouldn’t have made it there without some of their expert guidance!
