Hi,
I'm using DFI Ultra-D NF4 mobo and i'm using the 3/29/06 bios update..

my prob is, i've o/c my pc and i always get the cmos checksum error IF i turn off the power source.. i mean if i shutdown the pc it won't come out but if i turn off the power plug and upon turning on the pc, the cmos error will come out.. do u get whut i mean?

btw, i've tried all kinds of method already :
- changing the mobo's battery
- re-flash the bios
- clear cmos

is there any way i can fix this prob? thx

since the mobo have features cmos reloaded, y doncha try to reload another bios from other slot. maybe the slot where u using currently have problem

i've tried saving and loading on the other bank from cmos reloaded.. but still no luck...

if u running on default setup oso like that ka?

seems to me that ur mobo is faulty.
maybe its a sign to get a new one

still got warantty rite?try claime at alphamatic

Do you plug in all the power connector in Mobo ?
give it a try.
last time i did encouter once cannot save BIOS setting just becoz i didn't plug in the floppy and molex power connector for mobo .

ya same here

u should have your 24 pins, one 5v and one 3.3v. and make sure ur gpu got enough juice too

sometime cmos failure is due to mobo battery problem. check it out.

i 2 think that the mobo is about 2 die on me.. and there's no warranty left..

i'll try to connect all the power cables bcoz i didn't connect the floppy n molex power 2 d mobo..
irangan, i've mentioned that i've changed the battery ler..

thx 4 ur replies guys

after connect the molex still cannot?

and did u bought the board 2nd hand? i yes, where and who u bought it from?

tried connecting all the power supply to the mobo but still no luck.. damn

probably has got nothing to do with the power supplies, more because your board is not able to retain the cmos memory when the comp is turned off. so that means everytime u turn off ur comp, your cmos resets. it happened to my abit nf-7 and after i change the batt its back to normal again.

try PM lys008 and ask him for the solution. i think he faced the same problem before.

last time i just flash back the new bios already ok... , i think different with your 1.
