recently my fatality an8 a strange problem...after i shut down with the stanby power on. a long beep sound will heard after i on the pc again. beep sound like" beep beeeeeeeepp" n follow by the normal beep sound.why????
i just set fsb @ 270 wif divider 5:4. is this course by the over vcore o vdimm???

For some tccd, ya, not cheap.
coz it promise go 600Mhz at 2.7~2.95V.

tat is older version of TCCD.
latest, go over 3V will gain more...
and price i can said is still affortable

Remove battery a while,
plug in back,
start the mobo and go to abit uguru in bios and check all your system temp...
fan slow will beep, cpu heat will beat... wrong ram timing will beep...
u need to post in abit forum to get more support....

cyberloner,

what is ur problem with me....did i borrow u any money and not return the money back to you when i purchased either DFI LP or Fatal1ty????

Lets talk here and not embarassed ourself in an official like (u know which one right)....

DFI has 4 phase power too. OTES is not necessary actually. Even without OTES DFI is able to clock very high. MOSFET can work at very high temperature, as high as 120-150C. 70-80C is just half of its treshold only. About yr 'stable clock', pls give supportive facts what u mean by stable clock. Do you measure the clock using an oscilloscope? If yes, why not u post the waveform of the clock here?

If you talk about layout, both Abit and DFI are good. Check here :
ABIT
DFI

If you wanna know results of O/C using stock board (no further mods):
here it goes

Also, if you are showing off with 385MHz of HTT, I don't want to disappoint u, but even MSI can reach 400MHz using a-sync timing. If u want real o/c do it synchronously with RAM. It's useless to get the CPU runs fast with a slow memory hogging its performance. If tat's the case, i rather run at a lower HTT to have better o/c performance. O/c is suppose to makes PC performs better, not just high numbers but poorer performance.

You might claimed me as a DFI fan, but I'm not. I just tell the facts and compare them. I'm not saying Abit is bad, but DFI is js doing better. Up till now I didnt even said Abit sux while I hv both of them died, and my DFI still survived until extreme stress test.

This is a quote from Anandtech :

Oh well, if DFI takes the place of Abit now, I would say Abit is good and DFI isnt tat good too. Neither DFI nor Abit pay me to promote their products, I'm js telling what i think is best with support.

i was a dfi lanparty nforce 4 sli d user and sold it because thinking of upgrading. then after a few weeks using my old pentium 4 rig, i bought abit fatal1ty an8 sli coz of hand itchy

what i can say in terms of overclocking is DFI is better because of its wide range of setting, and when i oc with abit, somehow i feel sthing is missing in the bios.. and when running benchies, the score is less than what i got with the same setting with DFI.

but in general use, as a student who use the same rig for assignments, i can say abit is better since i have never ever experience cold boot .. DFI nforce 4 is well known for this problem but not everyone experience it.. too bad i was unlucky with my board. and this DFI is board is very very choosy with ram.. cheapo ram wont run good with this board.. unlike abit which is more flexible towards ram compatibility.

i'm not suprise all reviews said that DFI is the best nforce 4 board since i myself also think that is true. but what i wanna say here the reviewers tested the board just for a few days or maybe some 2-3 weeks only and they wont have chance to experience any instability problem.
i used the board since march and the cold boot problem only appeared in july..

and i love to quote what i found in kelvin_hata signature :



DFI got a lot of problems, but still no other board can compete with it in oc..


owh n 1 more thing, i guess high htt shows what the board is capable off.. no matter at what speed ur ram is running.. just my 2 cents

for the Abit it is physically not possible to have options in bios to set drive strengths.

drive strengths goes by resistance.. 30ohms to 75ohms

1 and 2
3 and 4
5 and 6
7 and 8

those pairs share the same resistance.. 1 3 5 7 being weak and 2 4 6 8 is strong..

TCCD clocking should be better on DFI..

from personal experience of playing with both boards.. the DFI is still my choice..

Abit lacks many things.. altho they use japanese capacitors now like DFI.. there's still one big step away from DFI.. which is BIOS updates

time will tell...
no more argue
no more mobo fighting
no more promotion

lowyat mod keep del post... that is wrong... mod....

Yo irenic, i agree with you about the cold boot issue, it happens to DFI nf2 as well. It is fixed after the latest official BIOS update. For me there's no big deal becoz i nv turn off my PC. Uptime wise, DFI realy did better than Abit in my experience. I've no idea on the RAM incompatibility too, thanx for the info

About the HTT u mentioned, actually high HTT doesnt mean as much as running synchronous with RAM. It's bcoz HTT multiplier is always set to a certain value to get around 1000MHz, so going high isnt a big issue, js like setting to a high FSB but lower down a CPU multiplier doesnt mean shows the CPU real o/c potential. In my opinion, if the board can run sync with RAM at high speed, it needs a good stability to make sure the data transferred from RAM to CPU through the bus on mobo. Just my 2 cents

BTW, would u like to share the problems of DFI? I really wanted to know, thanx !

If only you are not obsessed perhaps you can spot the grass might be greener on the other side also.

the problem with my DFI was only the cold boot. beside that, all were perfect. i did a review and found out that my problem wasnt the normal cold boot problem. in my case, all the 4 led's were blinking and i found in one website ( either xs or overclockers.com .. not remember) they called it 4 leds of death.. meaning the board is dying hehe..
its weird becoz most of them who have the same problem are using high voltage ram.. but i was using ocz rev2 which is tccd chipset and i nvr go beyond 2.8 (2.9 in some cases).. even when i wasnt oc my system, everytime i switched off it took me at least half an hour to switch it on again..
i also very seldom switched on the pc since i stay in hostel and the electricity is free but one morning i wanted to restart the pc but instead of pressed the restart button, i pressed the shut down button.. then i never ever able to switch on my system again hehe.. so i changed to a new board at alphamatic system and straight away selling it. that time i sold it becoz i was thinking to wait for DFI crossfire and use my p4 rig for a while..
but one thing is i still prefer DFI for oc purpose. Since using this abit i never do serious oc although my 3dmark got higher score than what i got with my DFI hehe..
about the ram compatibility, i heard that DFI wont run well with value ram or d43 ram... my current abit works perfect with my ocz rev2 tccd and patriot d43 chipset..

It is true that DFI has problem to pair with value ram but this is fixed after the latest official bios released.

As for the D43 ram, I myself once paired the D43 with my DFI NF4 Ultra-D. The only problem is the divider. It wont work with any divider. But it still overclocked very well to 260FSB with a ratio of 1:1.

hehehe...I myself had the 4 LED issue before. I managed to make it running by using Safe Boot jumper after clearing the cmos. I was tweaking the RAM by playing with the timings and that led me to the 4 LED issue. I have no more problem with this mobo since i have found a stable speed and the best timings.

i think the thread needs to be renamed "Abit VS DFI" heh

i am not siding anyone here.. but like i say above Abit and DFI.. they are both great boards.. DFI being the one having the upper hand in overclocking than the Abit..

Ram compatibility wise they fixed it with having DRAM response time in bioses after 618 if i'm not mistaken

DFI boards still have the best TCCD clocking capabilities than the Abit.. the Abit does not have the physical capabilities to play with drive strengths..

I thought they've catched up since the POS AV8 i've been using for a while but don't think they quite made it there yet.. and one thing i'm really pissed off when i was using my AV8 and AN8 SLI fatality is the bios release that does not fix anything.. but instead it disables something

hehe babyelf, i js cant tolerate somebody who always say one brand is the best and another sux to max. It's very misleading. Thanx for sharing your valueable experience here
Well, RAM and certain compatibility issue can be solved by BIOS update, this works to my nf2 DFI UI. Up to now, i really cant find a single error and the board works perfectly well. I believe nForce4 based DFI can sooner or later fixed the problem.


Usual DDR RAM chip cannot exceed 2.85V according to specs, and Winbond chips should be around 3.3-3.5V. More than that of course will give some problems.

i'm not sure bout the DFI uncompatibility with value ram since the only ram i had paired with my DFI was tccd chipset ..Corsair XL (tccd), Gskill LF (tccd), and OCZ rev2 (also tccd) hehe.. i just said what i read in other forum..
DFI is indeed a better board in oc.. it cant be compared with abit or other board. maybe the current bios is good, which fixed all the problems that never be solved during my time with DFI .. or maybe i just unlucky to get a suck board.. i never ever manage to solve my 4 leds problem even using the tips given by other pro in overseas forum..
i really hope DFI will fixed every problem since i am targeting their crossfire board for my next rig hehe

after spending some hours playing with this an8 bios, i notice it has problem when running more than 227 htt @ 1T ram.. the system wont boot into windows unless i change the command rate to 2T..
sigh

both tccd & d43 have same problem.. anyone manage to solve it?

edited:: i tested using bios 13, 15 & 16. & i cant find any difference between bios 15 & 16..

normally users will stick at 13 coz its the most stable and less hassle than 15 and 16...but i my benchie below i'm using 16....juz to see the performance...

btw DFI users...here is one ex DFI/now Abit Kipas....(hahahhaha)

nope.. it's a known issue.. not fixes for it yet.. 1T will run up to a point only..

it's not the ram.. it's the processor.. only affects venice and sandiego so far AFAIK..

Mine,
166 = 270 HTT = Switched On + Boot = Like a charm...

Juz make sure voltage is above a lil bit to make sure enuff to run everything...
