Gigabyte P45T - Extreme = 665MHz and 650MHz Spi 1M

[redratamd]

After some tests on aircooling. I'm very impressive by this mobo. Ive just tested the F2.

Picture of setup

- E8400 Q750A
- OCZ Vendicator
- GSkill Pc10666 on dual mode ,single is the same thing.
- Hiper 580R
- Sunon 150CFM on the memory and NB

For beginning " full aircooling " ,after with the NB is watercooled by the Gigabyte system and 15L of water .

Settings 
 - CPU Clock Ratio : 6X
 - CPU Host Frequency : 600 ( 635 max for windows )
 - PCI Express : 100
 - CPU Clock Drive : 1000mv
 - PCI Express Clock Drive : 700mv
 - CPU Clock Skew : 150ps
 - MCH Clock Skew : 50ps
 - Performance Enhance : Turbo 
 - MCH Frequency Latch : 400 MHz
 - Sys Memory : 2.00D
 - Timings : 9-9-9-25
 - Sub Timings : Command rate on 2T but it's 1T on Cpu-z and Memset others on auto ,i've no more time for trying

I check with multimeter tomorrow.

 - Vcore : 1.29375V in Bios = 1.26V on Cpu-z. And you can look for Spi and Pifast on the screenshot :D
 - CPU Termination : Auto
 - CPU PLL : 1.50V
 - MCH Core :1.42V on air and 1.54V with water. 35°C in bios .
 - Vdimm 1.80V
 - Auto for others

I use Set FSB and i obtain 656 MHz on dual with 2 cores
I put water on NB : 661Mhz
I try with one core and NB watercooled : 665Mhz
The 666MHz was not validated .



I' m very happy to see that.
I run some spi and pifast. Don't watch the score ,because it's not the good OS and bad memory .


Spi 1M @650Mhz

Pifast 10M @635Mhz

I think 3D is around Pifast .

This is a good part Next with better memory and cooling.

Thx to Christophe of Gigabyte France.
