I thought that a new Bios was supposed to fix problems Not create them.

Here's my story.

I was having vary slight problems with stability "Blue Screen" here and there.

I asked for help here at Tom's!

This nice guy answered and thought it was the Ram voltages.

Not thinking so I went to looked for a
Bios update and saw all the things the P08 was "supposed to fix" .

So I updated it and went about my business.

Now I'm not sure if it takes 2 restarts before a Bios takes effect or not,But that's what it seems.

the next day I started up and it got to my desk top and Locked up!
I tried 6 times and same thing.

I thought it was a Virus or something!

Finally I got it to work by setting defaults in the bios.

It just went down hill from there,
Everything from starting up and locking my desktop,
To starting half way and restarting,
To locking up 20 min later,
To getting started and turning off but staying on?


then I knew it was the Bios.

Rolled back to my good old P06 and upping my ram volts 0.050v.

Working Great! "like it was" You ever try to fix something thats not broke? DON'T.

If I just would have listened to ( badge ) I never would have had any trouble.

So take it from me Newbies!
If a long time member of Tom's tells you whats wrong, LISTEN!

Thank you Tom's!!!
And all members!

And Thank you vary much badge for your good help.

I would advise Anyone to listen to badge,he's bean here for 39 Years!
I hope they give You an Award badge!

these are the instructions on updating bios for an EVGA 790i Ultra SLI. It's key that you update you bios with the manufacturer's release and follow the instructions exactly.

This link is where i got this information:

This BIOS is ONLY for the EVGA 790i Ultra SLI Motherboard (part number 132-CK-NF79-XX)
This BIOS is NOT for the EVGA 790i SLI FTW Motherboard

P08 Updates:

Improved memory support for 1600MHz EPP DIMMs
Better support for Hynix DRAM
CPU Microcode updates for Penryn CPUs
Improved Memory Compatibility
Improved overall system stability (including games)

BIOS updating can be accomplished VIA the below methods:


FLOPPY Installation - Recommended installation method
Download the following executable: NF79_P08.exe

Insert blank floppy disk into drive and run executable
Restart machine, and set floppy as the primary boot device
Press "Y" to program BIOS
After flash, power off PC completely, on reboot load defaults in BIOS


CD/DVD Installation - Recommended installation method
Download the following .iso file: NF79_P08.iso
Use a CD Burning software to burn the .iso image onto a blank CD (Nero, Alochol 120%, MagicISO etc.)

Restart machine, and set the CD Drive as the primary boot device.
The BIOS flash process will begin, Press “Y” to program BIOS.

After flash remove the CD, power off PC Completely.
Turn on the PC and load defaults in BIOS.


Windows Installation - Alternate installation method
Before updating your BIOS, please load BIOS defaults by hitting the delete key during POST and select: “Load Defaults.” Now select “Save & Exit Setup.” After that has been completed please follow these instructions:
Download nForce System Tools and NF79_P08.bin

Install nForce System Tools Suite and run the NVIDIA Update Utility

Once Update Center opens, Check the box “Clear CMOS” and then hit apply at the bottom right hand corner
Now select browse and locate NF79_P08.bin

Select load bios

After update center finishes, completely shutdown your system
Once the system is off, unplug your PSU and press the power button on the front of your case. (This will discharge the Motherboard.)

Wait 30-60 seconds to turn on or plug in your PSU and start up your system.
Press "Delete" to once again enter the BIOS, and load defaults. Save and exit; your system BIOS is now updated.

**not sure who badge is or what you meant by "...he's bean here for 39 Years!" since the internet hasn't been around that long. But hope my post helps anyone trying to update bios. Bios is a tricky thing if you don't know what you're doing.
