better rev?
the material used on this mobo is good enough to me adi
b4 it launches , i googled for the pic
found that it has only 3 mosfet at each phase of PWM


and this is what i get here , 4 mosfet~

If you try to google for TA770 pic , you can see 1R0M choke only
but take a look at this PWM , surprisingly it's R60 which i believe that it is better PWM choke than 1R0M
( Need to download datasheet and compare the spec if really wanna find out )


edited: random pic get from google search for comparison
this is 1R0M choke on TA770 in other country

that one i'm not sure

Experience sharing here. When i was using TF7050 and TA690G, both mobo are using these 1R0M chokes. When vcore add to 1.55v above, the chokes will start making noise. Yesterday i tried to add 1.55vcore on this TA770 with R60 chokes ... so far didn't hear any noise yet
maybe it is still new? or maybe it is better

Will try higher vcore later and i believe that the temperature is much lower for this R60 chokes when oc . Will find it out tonight

it's a 1R0M PWM with 3 mosfets
sorry pic not clear



i believe that the one that you referring is not northbridge temp.
i use my hand to touch the tiny HS for NB, didn't feel warm also .
you are looking at system temperature is it?
that one should be the surrounding temperature.
what kinda casing that you are using ?
Looks like air ventilation not good enough to me

CRAZY_OCCT.jpg ?
what's so crazy bro? the HTT ?


edited: saw it ....really crazy

tried bro ah_khoo's suggestion just now
instead of set the cpu multiplier manually , i leave it as 'auto'
problem solved, no more auto jump to 9.5 multiplier

best try so far...
3.6GHz with air cond assistance

edited: opps, one of the CPU-Z tab (memory) repeated
suppose i wanna show motherboard info

vcore quite high to me
same question, what's the ram that u are using?

bully me

hehe bro DJericzzz,
are you sure you don't wanna warming up 1st b4 get into hardcore?


currently i'm trying to find a suitable oc software for this mobo.
AMD overdrive 2.14 beta , setfsb 2.0.b.19a , clockgen 1.0.5.3 and Biostar oc tool II all tested
cannot work

p/s: the clock generator for this TA770 A+ is ICS 9LPRS477BKL

This is bad, means that this mobo cannot use to oc for validation for now
will try one more time again later

My highest stable oc is 3.8GHz
unstable one , 3.99GHz

hmm... actually i have my own way to define a good overclock mobo
a good oc mobo to me must meet these requirements:

1) HTT/ HT link highly overclockable
2) 'More than enough' for Vcore & Vdimm options
3) Those important ram timings & sub-timings must be available
4) bug-free bios ( things like TF6100-am2 cannot use 667 divider consider as bios bug)
5) OC Software such as clockgen or setfsb supported. This is important for validation
(actually not true to say like that , suppose it should be the software support that particular hardware. But i assume that u guys get what i mean here )
6) CMOS reload function must be available. This function is extremely useful when come to extreme overclocking
7) Maybe there are more but i cannot recall it now, will add in when i remember

For TA690G & TA770 comparison,

TA690G Pros

1) Powerful bios boot up ( Dunno how to explain this , what i meant is after set 400HTT in bios still bootable)
2) HT link is very overclockable
3) clockgen supported ( however, you need to know how to setup properly)
4) Suitable for extreme overclocking

Cons
1) Not enough vdimm? ( i know 2.6vdimm actually is quite high already )
2) Driver for the chipset and integrated gc are kinda unstable to me, need proper installation
3) Voltage drop ( For vcore actually i think it's good, can save electricity mar )

TA770 Pros
1) Enriched with PCIE 2.0 , HT5.2 , ESATA ...blar blar blar
2) max vdimm 2.9v ( But i still dare to not use that high )
3) Endless HT Link oc
4) No voltage drop


Cons
1) Currently no oc software supported ( Will test everything again one last time for 100% confirmation )
2) Buggy bios need to be fixed ( Gambateh, biostar bios programmer )
3) The HTT is not so overclockable for my 1st trial on it ( Stucked at 380HTT. Not sure why. Will verify it again some other day. Temporarily add this to cons 1st )

For time being, i would say that TA690G is better overclocker.
Let's see after bios update in near future, TA770 can become a fierce beast or not

break my record? TA770 cannot use software overclock for now
cooling not efficient enough already,
cannot go further


should push the proc 1st
why not use 10x multiplier?
for air cooling, try not pump more than 1.55v
turn off itself?
that's dangerous bro

ice + wc + clockgen

chilled water, you can try 1.7v.
that's max vcore that works for chilled water..
add more won't help
and don't forget to monitor the temp all the time
you are using ABIT nview mobo rite?
kinda weird to see that 10x multi couldn't be used
IIANM bro lohwenli also using the same mobo,
i think he don't have this problem

ape tunggu? waiting for you to post result

Mod , what's the highest clockspeed with stock vcore ?
nice result there

higher...higher
the 1MB L2 cache really make me

holycow.... flashed corrupted bios for that TA770
not sure bcoz of the file corrupted or i flash in OCed condition
now 911 rescuing

in my case , the boot block still working.
it prompts me to insert cd or diskette
now trying to make rescue disk,
dunno it works or not

i'm trying to make rescue CD now
sh*t , nv tot can come into such trouble

hang on, i will create rescue CD now

yesterday too tired, terus sleep liao

bro, bring some engineering sample for us la

why not use latest version of Super Pi?
