i7 930 + GTX 470 OC Problems

post #1 of 4
Thread Starter 
I am using this as a baseline for my overclocking (4.01 GHz with HT). My settings are either same or slightly higher with RAM timings on automatic. Nvidia drivers are latest stable (did a clean install of this twice) and DirectX is up to date. Only the CPU is overclocked with the graphics card left on its default settings. BIOS is at 1301 (latest).

I recently did a clean install of Windows 7 and have been plagued by BCCode 116 which is "0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)". Display would go black when I log in or some times after logging in.

I've adjusted IOH Voltage to 1.2 and the issue seems to improve but still occurs. Prior to the clean install, I was running under the same setting without any consistent issue (a few rare 0x124). I think I will have to play around with both QPI and IOH, should I be attempting my adjustments elsewhere? How far should I go with IOH?

Strangely enough - on the system default (no OC) my system boots through BIOS(?) part MUCH faster than when it's overclocked. Particularly it is noticeably slower when loading my HD. System is also stable with no OC. I also got my first BSOD yesterday (need to check which one it was) - I usually just black-screen and reboot.

Sounds like you accidentally set your hard drives to IDE mode in your overclock. Set them back to AHCI with 2.0 tables enabled and watch your boot times soar. It may also solve some of your issues you're having. Can't say how many times I've done this myself.

I double checked and it was always set to AHCI. However, I didn't realize there was a separate timeout for IDE (set to 5sec) and AHCI (set to 35sec). Adjusting the timeout for AHCI to 5sec lowered the boot time.

For the 2.0 tables, are you referring to the power management option? I don't remember that option off the top of my head but I enabled it.

EDIT: I decided to go back to the ASUS (linked in my first post) and give the 4.2GHz setting a go. Booting up looks alright, I'll give it some stress test later.

Any advice is appreciated.

I did manage to get a stable 4.2GHz OC with higher IOH Voltage and IOH PCIE Voltage. I then preceded to attempt a stable 4.0GHz OC and was able to achieve it with the exact same setting as specified in link in my first post. Strangely enough, this was not possible before...
