abit Introduces First AMD Phenom™ Ready Motherboard, the AX78

AMD 770 chipset with native support for AM2+ Phenom™ CPUs with HT3

abit today announced their latest AMD 770 chipset-based motherboard, the abit AX78. This is abit’s first motherboard with native support for AMD Phenom™ quad-core processors delivering best performance for true quad-core processors, HyperTransport™ 3, Dual Channel DDR2 1066 memory, PCI Express 2.0 and CrossFire X. The unique abit engineered features set you apart from others and warrant for a most advanced computing experience with abit’s patented Silent OTES heatpipe, 4-phase PWM for AM2+ processors, 100% Japanese made capacitors for lasting durability and the external EZ CCMOS switch to reset your BIOS without the need to open your computer case. Set yourself apart with most advanced computing.

With AMD’s latest Phenom™ FX processors you get true quad-core computing power through the implementation of four cores on one silicon. An increased L3 cache shared by all four cores allows for quickest access of your most accessed data. Native support for dual channel DDR2 1066 memory modules in combination with the latest HyperTransport™ 3 bus technology, which can reach an overall peak datatransferrate of up to 20.8 GB/sec., are only the most outstanding new features for AMD processor based platforms. This is the best foundation for ultimate performance in a megatasking environment.

For high-end gaming and visual performance the abit AX78 is equipped with two PCI Express 2.0 x16 slots (1 x16, 1 x4 bandwidth) supporting ATI CrossFire X dual graphics. For further upgrades with add-on cards, one additional PCIe x1 und three PCI slots are provided for. The integrated high definition audio is scalable up to 7.1 channels for a fully cinematic surround sound soundscape. Supporting a total of 10 USB 2.0 ports of which 4 are already accessible through the back panel the user has sufficient connectivity for other multimedia devices of all kinds.

abit SoftMenu
The complicated procedure of tuning or even just adjusting the BIOS settings frequently gives users a hard time. With this ease-to-use BIOS-based interface, you have direct access to all major system parameters.

External CCMOS Switch
You are able to clear the CMOS memory directly from the back panel, using abit's innovative new EZ switch. If you are pushing your hardware to the extreme and experiment with risky settings, you do not need to open the computer case to go back to save grounds.

abit Slient OTES
The abit patented heat pipe absorbs and conducts heat from the NB to a special heatsink at the PWM area where the airflow from the CPU fan rapidly exhausts the heat from the computer case.

On the abit AX78 motherboards, abit provides 4-phase-PWMs. With 4-phase-PWMs, the system is providing better power supply and increased stability. Moreover, each phase is composed of one high-side MOS and two low-side MOS. This design adds to a better power switch efficiency.

PWM Heatsink
To provide end-users with the best and the most stable system environment, abit designed a dedicated heatsink on the PWM area. Generated heat is efficiently dissipated and the system remains cool and stable all the time.

guess I can do it myself, so in Exact Mode all I need to do is set "Extra" to 1.1v then save and flash?

thats correct. just change exact tab - extra to 1.1 save and flash

thats correct. just change exact tab - extra to 1.1 save and flash

ok cheers will try later tonight but currently running at 720/950 with 34C load and no problems so far.

cool. here is a little guide i did for someone else

Download NiBiTor.v3.5a

save your bios file tools - readbios- read bios to file (save as orig.rom)

Then tools - readbios - read to NibiTor

then go to the voltage tab

then click on exact mode. Should say 1.05v Change this to 1.1v

Save bios (new.rom)

Get nvflash and stick it on a usb stick that can enter dos (or floopy) with your newly created bios

Then uninstall nvidea drivers and rivatuner if you have it installed


Boot into Dos
type *nvflash -4 -5 -6 new.rom* (without the *)

Asks you to confirm - press Y


Reboot back into windows reintall drivers etc

Open Nibitor tools - readbios - read to NibiTor

Go to voltage tab and in exact it should now say 1.1v

20-11-2007, 13:45:33

There are no voltages selected in Exact Mode on mine but guess I'll just go ahead and select 1.1v.

20-11-2007, 14:01:42

just 3Dmarked at 700/995 and got 14730


20-11-2007, 15:34:35


You don't need to hard mod to get the extra volts. There is a 1.1v bios

I know, I meant to get more than a measly 1.1v

20-11-2007, 15:34:53

14k+ is outstanding.

20-11-2007, 15:39:11

nice work. Really i should stick mine with a quad core and see what it gets

20-11-2007, 16:10:16

flash the bios and now multimeter shows 1.1v :D

will see how clocks now :)
