BSOD running prime95 "Blend" torture test, error 0x00000124 (Win7 x64)

After checking the manual, I managed to find the following:

I'm guessing this is the "C6" you're referring to:
1) RC6(Render Standby)
Allows you to determine whether to let the onboard graphics enter standby mode to decrease power
consumption. (Default: Enabled) - This will be disabled provided you were referring to this

2) CPU EIST Function
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. Auto lets the BIOS automatically configure this setting.
(Default: Auto) - This will be disabled

3) CPU Enhanced Halt (C1E)
Enables or disables Intel CPU Enhanced Halt (C1E) function, a CPU power-saving function in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to
decrease power consumption. Auto lets the BIOS automatically configure this setting. (Default: Auto) - What should this be set to?

4) C3/C6 State Support
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically configure this setting. (Default: Auto) - Should I set this to C3 or Off?

Looks like things have changed; I'm afraid I can't find any mention of "C-STATES" anywhere in the manual. The "Power Management" section of the manual contains nothing applicable; looks like "Advanced CPU Core Features" is the only section that contains settings of this nature. Here's a copy/paste from the manual:

1) Core Current Limit (Amps)
Allows you to set a current limit for CPU Turbo mode. When the CPU current exceeds the specified current limit, the CPU will automatically reduce the core frequency in order to reduce the current. Auto sets the power limit according to the CPU specifications. (Default: Auto)

2) CPU Core Enabled
Allows you to determine whether to enable all CPU cores. Auto lets the BIOS automatically configure this setting. (Default: Auto)

3) Hyper-Threading Technology
Allows you to determine whether to enable multi-threading technology when using an Intel
CPU that supports this function. This feature only works for operating systems that support multi-processor mode.
Auto lets the BIOS automatically configure this setting. (Default: Auto)

4) CPU Enhanced Halt (C1E)
Enables or disables Intel CPU Enhanced Halt (C1E) function, a CPU power-saving function in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power consumption. Auto lets the BIOS automatically configure this setting. (Default: Auto)

5) C3/C6 State Support
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically configure this setting. (Default: Auto)

6) CPU Thermal Monitor
Enables or disables Intel CPU Thermal Monitor function, a CPU overheating protection function. When
enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. Auto lets the
BIOS automatically configure this setting. (Default: Auto)

7) CPU EIST Function
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. Auto lets the BIOS automatically configure this setting.
(Default: Auto)

This is driving me bonkers, and should be incredibly simple. I'm considering opening up a support ticket with Gigabyte just so they can answer this basic question.

I'm hoping to have the chance to review the BIOS this evening to see if I can figure out how to disable what you've outlined and do the next stress test...will keep you posted =)

Haven't had a chance to do the additional testing yet, hoping to be able to try it before Friday!

As a side note, I'm considering purchasing this bad boy to nullify the PSU as being a potential problem (figured I'd share the deal as it expires on 8/31):

I finally got Microsoft Office reinstalled, and had the opportunity to review a log I captured using HWiNFO during the very first prime95 blen torture stress test where the computer ran for 14 hours and 15 minutes before it crashed with the original BSOD. I figured I'd attach the file to this post in the event it can maybe help shed some light on what went wrong. Please note I had to .rar the file in order for the Seven Forums upload system to accept it.

Thanks,
