Killed my BIOS chip on DFI NF4 - why??? Made no mistake........

**HARDCORECLOCKER** · 04-09-2005, 01:07 PM

O.K. - Here's the story:

After some time with my BH-5 I decided to go for another try with my TCCD.

Shut down the rig, unplugged the power cord and waited till all onboard lites were off.

Swiched the jumper to the position for 3,3V rail and replaced my BH-5 with the TCCD.

Cleared CMOS and started the system - long beeps, a constantly blinking power lite on front panel and 3 red onboard lites at the diode area.

Hm, rebuilt all like it was before but still no POST. Then tried 3 kits of RAM, long CMOS clear, removed the battery, unplugged all USB connections and all the other tricks but still no go.

Fortunately I have a second BIOS chip - threw it in and ooooooops, rig is running again !!!

Hm again - gave the first BIOS chip a second try - but again no go, definately killed. But why?

Replacing the RAM can not kill BIOS and when I swiched the jumper for the voltage rails there was no power to the system but the battery.

Never heard that it is recommended to remove the battery before setting the jumper........

Conclusions:

1) Any ideas what happened here?

2) All You people with 3 red LEDs on and spinnin' fans but no boot try a second BIOS chip.

Thanks for the heads up, unfortunately I doubt that most of us have a second bios chip floating around.

You can always hotflash

**Skip** · 04-09-2005, 03:41 PM

yea just hotflash so you have that bios chip incase the problem happens again. i would suggest hotflashing as soon as possible.

**BLHealthy4life** · 04-09-2005, 03:56 PM

what is hotflash?

I don't know, something life-saving perhaps?

my bios got corrupt when I changed some of the mem timings too low. luckily the bootblock wasn't damaged, but it was all buggered up for a while. At first I just got the beeps, then turned it off. Turned it back on and it came up to the bootblock saying checksum error, please insert floppy... turned it back off and walked away pissed (and to find a floppy drive). Came back and it powered on to the Lanparty splash screen as if it'd just had the cmos cleared. Went into bios and there were all kinds of droppings in the menus and chopped text and whatnot...so I promptly re-flashed and the problem went away.

DFI and bios death, two good old friends

Bios savior fever ahead

**conrad.maranan** · 04-09-2005, 05:39 PM

There are too many threads open at the moment dealing with DFI problems. We only need one active thread since most of the issues being discussed are already being discussed in another thread.

Please refrain from starting up threads on the same or similar topic from this point forward. In the future, multiple threads on relatively similar issues will be consolidated into one thread.

Please refer to the AMD section Guidelines for advice and suggestions on how to initiate and participate in discussions.

Thanks.

I totaly respect what your saying conrad, but I believe HCC is bringing in a new concept which would have probably been lost in the 30 odd page DFI thread. I agree compleatly that there is a trend arising to post willy-nilly in the AMD section, but I do think this has worth outside of the huge DFI thread. Do you enjoy trawling through 18 pages of posts looking for little gems like this?

Subscribed - THX. That was exactly the reason I started a new thread.

i feel worried about changing memory now if it can cause problems

already fed up of computers atm, took me a week to sort out my dfi ultra-d

**Theo404** · 04-10-2005, 04:11 AM

Might be an idea to try and fully discharge the components before messing with them, I read in another thread (the name escapes me) that you should pull your power supply cable, wait a few seconds then press the power button (on the PC). Makes sense to me because I tried it and the leds came on for a second and the fans moved a little, suggesting there was still stored current somewhere.

Nah - think it was not caused by changing RAMs - has to do somethin' with the Vdimm jumper in my opinion.......

**Theo404** · 04-10-2005, 04:19 AM

Ya, far more likley it was a surge or shock when you switched the vdimm regulating curcuit over to the 5v line.

**Skip** · 04-10-2005, 04:37 AM

it could just be a fluke or something?

yeah you are right. i always unplug the system flip the psu's switch and wait for all the lights to go off on the mb before even sticking my hand in the case! i would be willing to be that it was some sort of surge that caused the problem not just changing the memory.

peace perc,

Absolutely...the best precaution. I think OPB posted the warning way back....

**mad mikee** · 04-10-2005, 04:56 AM

1. Oskar said awhile ago that yeah you can do bad things if not COMPLETELY discharged so maybe a factor.

2. Try hotflashing (boot, pull working chip, and replace w/ one you wanna flash , then flash the 'new' chip) including the boot block (just to be sure) the 'bad chip and see if that brings it back.

3. Thinking it was prolly 5v jumper since I have swapped memory in this board literally hundreds of time w/o issue (other than occasionaly loosing a cap off the dimm

)

peace perc,

Hey folks I know that and did it, turned off sys, swiched off the PSU and unplugged the power cord, waited for 2 minutes and all the lites were out of course.......

**Theo404** · 04-10-2005, 05:05 AM

I dont think anybody actualy got what I said.

Of course you have to power down the system and pull the PSU chord, everyone does that. The point I was trying to make is to push the power button on the system after you've done that! Give it a try. on my system the leds came on for a few seconds....ie. still juice in it.

Now I see Theo - sorry for misunderstanding. Will do that next time. THX.

**|SiLA|** · 04-10-2005, 08:06 AM

it happened to my friend to 2 weeks ago..he was benching with his new geil ultra-x(bh5) then since it was sucking bad he changed back the rams with the gskill..and suddenly he couldn't boot 3 leds on(it means can't "find" the ram FYI) told him maybe it was the mem controller died..then i also told him to use single channel using the second orange slot..then worked..then worked also in DC

dunno where the explanation is on why happened but it's scary

Sorry about that.

So far when ever i've made changes i've unpluged everything and discharged and i havent had any problems. "Knocks on wood"
