Hey Guys,

I wanted to inquire with the professionals on the settings I have setup for my motherboard to make sure everything is tweaked to its max potential. As of right now, the the CPU is prime95 stable at 24 hours, but after so much research, I figured I would ask that you guys 'check my work', see if there is anything I could tweak or change that I might have missed, forgotten, or misread. Nothing too crazy, I hope. Let me give my specs first:

CPU: Intel Q9550 2.83ghz @ 4.00 ghz
Motherboard: Gigabyte EP45-UD3R Rev. 1.1
RAM: 2X2GB Corsair XMS2 1066
Video Card: EVGA GTX 470 (overclocked also, but thats for another post)
Hard Drive: Western Digital 500gb 7200rpm, 32mb Cache
Power Supply: ATX Ultra 1000 Watt
Cooling: 4 x 120m Fans, Thermal Take Blue Orb
O.S. Windows 7 Ultimate 64-Bit
Sound Card: Sound Blaster Audigy SE
Monitor: Acer 1080P HD 24", Samsung 19"

There's probably more info then anyone needs there, but I figured I would tag along the whole setup just in case. I mainly use my Computer for for work during the day (I'm a 3D Artist for Video Games) and playing WoW with my wife for a couple of hours at night.
Alright then, onto the BIOS.

Thanks Again for any help:

Alright, I have other information as well, such as what can be found under the separate RAM Channels, but for now I think this should do.

Any help would be appreciated, so if anything catches your eye, or if you see something you personally like to keep on/off, let me know.

I really thank you all for your time, and I hope you all had a happy and safe holiday.

A 24hrs stress run without errors that is absolutely stable enough and have nothing to worry about.

Hey Wen, thanks for the response. I guess I'm not worried as much as I was just curious if there is anything that can be optimized that isn't necessarily set properly right now. Any other feedback would be great.

I'm not an expert on voltages but yours doesn't look bad. IIRC 4.0GHz is pretty good for a quad processor with air cooling. But you did leave one thing out- what were your temps while running prime95? That is the thing you need to watch.

Oh, temps are good to go man. Thanks for bringing it up. I have one stuck sensor that never goes below 37 C, but the rest sit at 34C idle and prime blend maxes it about 65C, sometimes it would spike up to 67, but nothing crazy, and this is only when I prime blend. It was important that temps didn't go over, since processors peak at a constant 100% usage on all four cores when I'm rendering, and some of the rendering I do can go for 8, 12 or even 72 hours straight.

Great question, though. Thanks for reminding me to mention this.

Nothing wrong with your settings. You avoided all the usual mistakes. The only thing I would do is reenable EIST (SpeedStep).

I have a similar system in a UD3P, unfortunately with a C3 core and a relatively high VID. The best I could do was 3.6 GHz.
