they are just bein wise in spendin their money... smile.gif

imagine, d money spend for e21x0 + dfi dk is less than any x3 or x4 + dfi dk, but u get better performance w/ d blue camp. why not? wink.gif

sumore u can clock d shite outta e21x0, can x3 or even x4 do that atm? blink.gif

Biostar TA770A2+SE Special Edition

Every thing look good chipset AMD770 with SB700 .  thumbup.gif  and SE version has a slightly different PWM design but sound quite old version  doh.gif
*
this is a downgraded version of TA770
It seems good because added one more choke,
but they reduce the amount of mosfet for each phase already.
theoretically it can handle larger amount of current,
but the reduction of mosfet definitely will leak to overheat issue,
i would say that previous version is a better one.

Look at the mobo layout carefully, nowadays they use cheaper and outdated onboard audio codec chip for almost all coming up T-series mobo.
Realtek ALC662 6-Channel HD Audio, swear to god i will never buy any T-series mobo with this spec rclxub.gif
i just rma my TA770 few days ago, hopefully i won't get this second edition sweat.gif

Actually 4pin and 8pin is same...the most importand is the rail voltage for 12v2 is how much volt and amphere ...example like tis  11.90v  with 18A
*
what different between 4 n 8 pins?
the latest one is 4 or 8 pin? icon_question.gif

bro, forgive me for shallow minded, isn't it 8 pins supply more stable & "clean" voltage? unsure.gif

yeah, i feel it very unstable. Typing this in IE also lagging. How much Vcore you used at 3.0ghz? I tried to increase the Vcore in Mobo Bios, but the Vcore still same. I think it because my chapalang PSU.

apparently ur mobo supports up to 1.55vcore but many says that it's a cheap board and might fried if u raise it too high :S

it's the mobo and not sure it's the psu? ..Orthos should run for at least more than 6 hours to show that it's stable...

allright. I will run orthos and leave it overnight. But last time can more than 7 hours. lately only i found this little weird problem.

does anyone here using DFI Mobo with Genie Bios in it ?? .. damn i got hard time to understand every single thing of it sleep.gif ... anyone mind to teach me ?? .. wanted to OC my BE to 3.0 or 3.2 ...

increase your Vcore to 1.4v to achieve stable 3.2GhZ.

He need to increase Vcore also. Maximum clock speed for stock voltage for BE 5k is 3.1GhZ.

that is pic of Genie Bios .. sleep.gif

which 1 is Vcore ? .. CPU VID ?

DRAM config page - we will leave this for its own subsection.
LDT and PCI Bus control - defaults here are all you need
PCI Device control - here you find the switch for ULI raid and SATA setup off the South Bridge.All sata controls and the onboard LAN's enable or disable.

Overclocking features


FSB Bus Frequency - Otherwise known as HTT Bus frequency, this is where we tweak up Bus speed.
LDT/FSB Frequency Ratio- Here we set the LDT multiplier. Remember CPU speed is worked out from the LDT bus speed, CPU multiplier and the LDT ratio.
CPU/FSB Frequency Ratio - commonly known as the CPU multiplier, here we usually down clock the multiplier so that we ran ramp up the HTT frequency.

RD580 HT PLL speed - The RD580 chipset has 2 modes for setting the clock on the Hypertransport speed, normal(LOW) and High speed.
Sub 250HTT running LOW speed is just fine, over 250 choose HIGH speed

HT Bus NMOS Drive Strength, HT Bus PMOS Drive strength 0 to 31 - These options cover the drive for the send and recieve functions of the Hyper transport bus.
For high LDT overclocking 25 or higher may be needed, I use 31 on both options when pushing 300X5LDT. If you are not interested in LDT overclocking remember the board will do around 1200HT easy so you should only ever need to set either 5X or 4X for the LDT multiplier and leave the drive strengths at the default of 5

HTBus Reciever Impedance 0 to 31 This option controls the impedance the board sets to counter signal reflection on the RD580 chipset. SO, as you clock higher you may need to increase the value higher. I have tested at 5 and it does seem ok for most overclocks, if you are ramping up the LDT you may find upping this value gets you a higher stable overclock.

Between 5 and 10 seems to be the settings to test, 10 actually gets me the best clocks with 2gig kits.

CPU HT Bus Drive strength Weak or Strong options.
for high LDT Bus overclocking choose Strong
K8 Cool n Quiet.....if overclocking best to leave this disabled.

Voltage Controls


CPU Vid Options here depend on the max VID your CPU will allow, its usually 2 options above the normal Vcore the CPU runs at.
CPU VID Special Control Here you can set the over volt for the voltage you want to run on your CPU, remember to to keep this below 1.6V for most CPU's if you can, to much Vcore can damage your CPU.

Dram Voltage control Here we find the finest Vdimm control seen on any motherboard. Dependant on the Powersupply voltages to your mothertboard you may see voltages actually measured on the board higher than you set in bios, as a rule the voltage on the board is usually 3 options higher than you set in bios, IE, 2.6 in bios will give 2.65V on the motherboard....try to keep this in mind

SB PCIE Voltage
- this option in reality is the SouthBridge Vcore voltage.A slight bump will allow for higher PCIE overclocks and can aid in getting your general overclocks stable
NB Analogue Voltage - ???
LDT Bus voltage - when overclocking the LDT bus you will need to tweak this voltage higher, small jumps here, don't ram the voltage
NB Core Voltage - vcore for the Northbridge, high LDT and PCIE overclocking gains from a bump in voltage here.
