In 2008, Intel launches 2 latest Chipset which are P45 and X58 plus ICH10.
These architectures are new goal for all the motherboard manufacturers.
“P” series always become the mid-high end products.
As per the experience, Intel P35/45 is still the most popular products as the OC ability is easily to catch “X” series.
GIGABYTE is always very good at Intel MB product line and separate products into DS3/DS4/DQ6 3 levels,
the familiar model names for users buying guide by budget.
In new P45 Chipset, GIGABYTE launched a new model is more hi-end than DQ6.
The leading role of this test - GIGABYTE P45T EXTREME.
For a long time, DQ6 is always the most hi-end model.
However, after then Extreme series is the new flag ship.

DRAM provide extra2 phase PWM, the next by is 24-pin power connector
CPU PWM, use 6+6 phases PWM and support DES advanced technology.
The new VRD11.1 design guide, Intel E0 CPU will run with Intel latest energy saving technology.
In my personal view, the 6-phase CPU PWM or support 8-phase in digital are good enough for the hi-end model.
Ex. GIGABYTE uses 6+6-phase, DFI uses 8-phase digital.
The entry like Biostar uses 4-phase PWM also can run Dual core and Quad core OC.
The great benefits are power saving and environmental protection.

The heat sink comes with board
GIGABYTE always use very good quality components compares to the same price level products.
This time uses 100% cooper thermal module which is good looking and better thermal dissipation.
This thermal module is very beautiful design. There is another 2-phase PWM for MCH.
For the water-block built-in module, GIGABYTE provides a special and power thermal kit - Hybird SLENT-PIPE
100% cooper provides the best quality for thermal solution
The Hybird SLENT-PIPE install at the PCI-e slot position.
It also enhances the whole system thermal solution.
(Installing Hybird SLENT-PIPE will occupy 1 PCI-e x1)

EasyTune6 integrated all necessary features and info into one software. It is very convenient.
MB also has LED to display the DRAM voltage and PWN loading status.
Just mention, this time I also use JETART Nano Diamond thermal pad to replace Y-500
VGA
Using Gigabyte HD4870 DDR5 512MB CorssFire which is the hottest VGA combo at the moment.

2008 most popular game - Crysis
Now, the highest C/P values VGA are 4850 and 4870 for sure.
GIGABYTE HD4870 DDR5 512MB CorssFire is really fast, especially in Crysis it has very high pages ratio even in 1920x1200
DRAM
Uses CORSAIR Dominator TWIN3X2048-1800C7DIN, supports XMP
Enable XMP in BIOS, it runs 450x6,DDR3 1700 CL7 7-7-20 2.1V automatically.
Passed SP2004 Blending XP
CORSAIR Dominator TWIN3X2048-1800C7DIN official spec is DDR3 1800 CL7 2.0V.
GIGABYTE has more improvement room here.
DDR3 1933 CL7 6-5-20 EVEREST bandwidth
The DRAM voltage and frequency after OC are mid-high standard.
However, there is still more3% to 5% room to improve.
P45 combo with ICH10R. I use the best stuff to see the capability of the new ICH
SAMSUNG 64GB SSD SLC,
market price is 700 USD. Also heard the price drops to 580 USD last week.
EVEREST
Tune
This SAMSUNG 64GB SSD SLC is much faster than the MLC version, the Read/Write life cycle is also 10 times more.
The transfer performance is really amazing.
It takes less than 20 minutes to install the Windows XP. It is also very fast to enter the XP.
ICH10R has its own advantage, because this SSD only reach 100Mb/s in ICH7.
ICH10 is really improved a lot in performance.
CPU
Intel C2D E8400 for dual core
I believe 99% think the stable frequency after OC is the performance standard.
615Mhz SP2004
Dual Super PI 32M
This is almost the best OC capability in the all P45 boards.
Running stable in 610~620Mhz is really amazing.
Coming more for dual core CPU extreme OC
644Mhz Super PI 1M
Mostly 646~649Mhz also can enter to OS and get CPUZ certified.
Many users use software OC to get the higher frequency for CPUZ Cert This is my first try for software OC.
Using software can pull in the frequency for more 10~15Mhz to make the extreme OC be greater.
However, in this condition, you cannot run any software.
If I don’t mention it, the results are all from BIOS adjustment.)
In Quad Core CPU, it can run stable in 500Mhz and passed 1M at 530Mhz.
It proves the P45T EXTREME is in very high standard for both dual core and quad core system.
The Energy Saving Software from GIGABYTE-DYNAMIC ENERGY SAVER
Later called DES. DES needs C1E to operate.
DES disable, 2700Mhz shows 15.51W
DES Enable, 2700Mhz shows 13.46W(4-phase)
DES Panel provide lots of info, usage duration, power saving watts and CPU current power consumption.
DES Disable,4050Mhz shows 80.07W(12-phase)
DES Enable,4050Mhz shows 45.81W(8-phase)
80.07-45.81=34.86W, the full speed power saving by DES display.
But this is the software come with the product. I have to double check it.
This time I use Seasonic Power Angle as the tool.
All equipments are the same.
DES Disable,4050Mhz system shows 339W(12-phase)
DES Enable,4050Mhz system shows 292W(6-phase)
The all system saving is 339-292=47W.
It’s 35W more than the DES displayed. DES is a good prediction software.
GIGABYTE P45T EXTREME
Strength
1.100% Japan made solid capacitors. Full LED display under system operation. ATI CorssFireX supported
2. Rich applications in OS. They are all powerful function and exquisite interface.
3. BIOS provides wide voltage range and the options are never seen before in GIGABYTE products
4. Dual Core/Quad Core CPU OC are excellent. It let CPU has 20~50Mhz possibility
5. High cost 100% cooper thermal modules. It is hard to see in the other brands boards
6. Debug LED, Power/Reset/Clear CMOS buttons
7.6+6-phase dynamic power saving with Intel latest VRD11.1 PWM design. It combines very well with own DES software for lower power consumption
Weakness
1. The cables are too less. The cables are enough but should be more for hi-end products
2. DRAM voltage is higher than other brands. Also hope the future BIOS can support over DDR3-2000.
3. Clear CMOS battery is under the cooper pipe. Not easy to use.
Performance ★★★★★★★★★☆
Components ★★★★★★★★★★
Outlook ★★★★★★★★★☆
C/P ★★★★★★★☆☆☆
GIGABYTE EXTREME series is really for Enthusiasts.
For the scoring system, I am always very strict for it.
This is the 1st product I ever score 10 stars.
It is because GIGABYTE really puts a lot of effort in components.
7 stars in C/P, because 330USD price is too high even with very great OC and components.
The hi-end board C/P is always very low. It’s coming with DDR3, so I minus 1 star from 8 to 7.
I’ve been testing many P45 boards, the good OC board should run stable at dual core 600Mhz and quad core 500Mhz.
DRAM must reach DDR2 1200 and DDR3 1800 CL7.
The 9 stars are scored by this standard.
I still have to mention, I hope P45T EXTREME DDR3 OC ability can be improved by future fine tuning BIOS to reach 2000.
No matter what product range, 330USD is still also very high C/P value with GIGABYTE P45T EXTREME.
Mid-end P45 has Biostar which are between 130~160 USD and hi-end OC P45 has GIGABYTE P45T EXTREME.
If you cannot find any points to upgrade from P35 to P45, you can wait and see for awhile.
However, for personal view, the P45 runs stable at 600MHz is improved quite much than P35 in OC capability.
GIGABYTE launched P45T EXTREME(DDR3) and P45 EXTREME(DDR2) make the more choices for Enthusiast market.
Windwithme reviews all take much time and effort.
Normally, it takes1 to 3 weeks to complete the article.
If you think my review is good for product info and buying guide, please reply my post.
Hi windwithme
Im planing on buying the GA-EP45-EXTREME, and I stumbled on your product review.
Thanks for the review i can tell you've really spent the time in researching this product and im now 100% spent of buying this for myself.
Im new into overclocking so i wanted to ask, im planing on buying the Intel Core 2 Quad Q9550, 2.83GHz with this board(DDR2 1200 version) and was wondering if I should purchase 800mhz ram or go for 1200 as thats the max mhz it could take, tho im gessing 1200mhz ram would unbalance the cpu:ram ratio ?.
Is the overclocking software simple to use for a beginner like my self ? can I just shift everything to max and the software will do all the calculations it self for FSB,voltage and all that jazz or do i have to manually figure out the mathmatics behind the system ??
To the other poster, if you get the ddr2 version, it's pretty simple to determine what RAM you will need.
The CPU Multiplier x the FSB = the CPU speed. Yours will be 8.5. Stock uses 333 x 8.5 for your stock speed.
And since the FSB will decide your higher over clocks, your RAM will need to at least be near this.
To get from 2.83 to 3612 Mhz, you'll need a FSB of 425. So in sync mode, the RAM will be at 850 Mhz.
While in sync mode, its FSB x 2 = RAM speed. Pretty easy.
So basically, if you want 3.6 Ghz, most name brand decent 800 Mhz stocks can maintain their stock timings and stuff at about 425 FSB or 850 Mhz.
My reaper x starts to loose its 4-4-3-15 timings near there as well.
If you want to over clock any higher, all you will need is 1066 RAM.
Since to get 1000 Mhz you'd have the processor at 8.5 x 500 = 4250 Mhz.
So there you have it!
800 Mhz will work for 3.6 Ghz or lower, and keep their same timings. (Some you could loosen from 4-4-4-12 to 5-4-4-15 and get a bit more speed at the cost of timings.) So could over clock a bit higher on, if you wanted to, or needed to.
For over 3.6, 1000 Mhz or 1066 will suffice until the chip explodes!
I think i will pick up one of the better P45 boards, too. Dunno the brand yet, but they get the good FSBs!
Thanks for the review, the only drawback, x8-x8-x4? Wonder how that effects the powerful video cards performance! Isn't that a bit low on lanes?
Would i be correct to say i could run RAM with the intel Q9550 2.8ghz multiplyer 8.5 and get these results?
+ 1066mhz ram - at FSB 500mhz = 4250mhz cpu
or 1200mhz ram - at FSB 600mhz = 5100mhz cpu
I read in the over clocking forum "how to overclock" that with a FSB above 400 you would have to start pushing your Voltage above 1.4v and chances are above that limit and you'll fry your CPU is 600mhz possible as you've stated windwithme ????
I have a new Gigabyte P45 and it is great, I find no need for anything over 400(1600 FSB) which give me400x9.5=3800 or 3.8Ghz on my E8500 which is rock solid with mem@1:1 800 5-4-4-12 seems to be the best performance thats on xmp extreme settings.
