Official GIGA P35-S3/DS3/DS3R/DS3P/DS4/DQ6 bios/info thread

[zsamz_]

I did some research for y'all. It's a E6420 versus my brand new E6850 on my P35-DQ6. I used a Kill-A-Watt to measure power consumption.

Summary:
1. The E6420 kicks its own butt, as it can OC to 3.2GHz at its stock voltages on this MB!
2. The E6850 kicks everything, as it can OC to 3.6GHz at stock voltages and uses less power while doing so; 20W less at 3.0GHz! 10W at idle! Thus, with this CPU, I can idle at the 3.6GHz setting, and use very little power, but it will use 80W more when fully loaded. It's the best of both worlds: low power when idle, high power when not idle. Now if only nVidia can do that...
3. I couldn't get 3.8 or 4.0GHz at "auto" voltages". Trying not spend too much time OCing this thing...
4. Using "Auto" voltages on this MB makes power consumption go through the roof.


Setup:
- P35-DQ6
- ambient temp around 76-80F
- F5g BIOS (F5L didn't work as well at 445FSB, 2.4x mem multiplier)
- 2.4x mem multiplier seemed the most stable
- dual 24" LCD monitors
- mem at 2.0V 1066MHz 5-5-5-5-9 (except at 375MHz, where it is 900MHz)
- nVidia 8800GTX BFG OC 600MHz/900MHz
- Scythe Ninja cooler with NExus 120mm fan at 12V
- Corsair 520W PS; at this power range it is around 85% efficient, so I included these numbers
- APC UPS used 30-35W at idle; the two monitors together use 86W; thus PC box is using around 120W less than shown, and PC parts are using 85% of that number
- In the lowest idle case, it's (300W - 120W = 180W) * 85% = 153W
- In the highest OC case, it's (444W - 120W = 324W) * 85% = 275W, thus the CPU and associates VRMs are consuming 122W more over minimum!!
- Temps aren't final; burn in time was around 30 seconds; TAT was used for burn in and temp reading



E6420, B2 stepping
- In Windows, idle:
- 133MHz FSB bus, all stock voltages (0.8GHz 6x) - 35C - 306W - (underclock, and memory was at 533MHz - since CPU was same temp, 35C seems to be min temp)
- 266MHz FSB bus, all stock voltages (1.6GHz 6x) - 35C - 310W
- 333MHz FSB bus, all stock voltages (2.0GHz 6x) - 35C - 310W
- 375MHz FSB bus, all stock voltages (2.25GHz 6x) - 35C - 311W (mem at 900MHz)
- 400MHz FSB bus, all stock voltages (2.4GHz 6x) - 36C - 312.5W (mem at 1000MHz)
- 445MHz FSB bus, "auto" voltages (made 1.46Vcore) (2.67GHz 6x) - 44C - 340W

- In Windows, TAT on both cores:
- 133MHz FSB bus, all stock voltages (1.066GHz 8x) - 44C - 335W - (underclock, and memory was at 533MHz)
- 266MHz FSB bus, all stock voltages (2.133GHz 8x) - 50C - 366W
- 333MHz FSB bus, all stock voltages (2.666GHz 8x) - 54C - 380W
- 375MHz FSB bus, all stock voltages (3.000GHz 8x) - 58C - 389W (mem at 900MHz)
- 400MHz FSB bus, all stock voltages (3.200GHz 8x) - 60C - 396W (mem at 1000MHz)
- 445MHz FSB bus, "auto" voltages (made 1.46Vcore, up from 1.35Vcore) (3.56GHz 8x) - 66C (30s burn in time) 444W - Got BSOD from heat? Normally single thread prime stable.


E6850, G0 stepping (memory is at 1068MHz in most cases)
- In Windows, idle:
- 333MHz FSB bus, all stock voltages (2.000GHz 6x) - 19C - 300W
- 356MHz FSB bus, all stock voltages (2.136GHz 6x) - 19C - 305W
- 400MHz FSB bus, all stock voltages (2.400GHz 6x) - 24C - 305W (mem at 1000MHz)
- 445MHz FSB bus, "auto" voltages (made 1.44Vcore, up from 1.32Vcore) (2.136GHz 6x) - 26C - 328W

- In Windows, TAT on both cores:
- 333MHz FSB bus, all stock voltages (3.0GHz 9x) - 39C - 367W
- 356MHz FSB bus, all stock voltages (3.2GHz 9x) - 42C - 376W
- 400MHz FSB bus, all stock voltages (3.6GHz 9x) - 47C - 386W (mem at 1000MHz)
- 445MHz FSB bus, "auto" voltages (made 1.44Vcore, up from 1.32Vcore) (3.560GHz 8x (not 9x)) - 54C - 416W

last thing you wanna do is go on auto lol voltages crazy

i can get to 3.8 with 1.4v
4.0 i need 1.55
i'm happy with 3.8 though 21c

Why does my Gigabtye keep on restting to stock speeds after every reboot even after I set the correct voltages?

here too lol just happens

Try starting at default settings and tweaking one thing at a time, save and exit bios each time you tweak something until you find the setting that's causing your problem.

I do that but as soon I try add some FSB it just resets completely no matter how much voltages I add. Memory settings and voltages and so on.
