First 8rda+ Vdd mod casualty...

My 8rda+ went up in flames at 1.94v Vdd today... The chip right next to the chipset voltage regulator (1cm to the left) catched fire (no kidding, it was glowing as bright as a LED).

I was going to overclock, so i slowly turned my pot.
mbm5 reported 2.04v, so i turn it back and it said 1.94v, i was aiming for 1.90v, so i turned it a little lower but windows froze.

Rebooting didn't help (motherboard turn itself of immediatly) so I unplugged the grounding of the mod (i didn't solder it on pin 4, but connected it to a fan connector grounding). Rebooted again and the chip right next started to glow... f*ck.

It killed my vidcard as well!!!!! I've yet have to test my friggin' expensive ram (2* Corsair XMS 3200) and CPU (XP2400+). I hope they still work...

By the way, my northbridge was watercooled.

Damnit. :'(

ARGH
sorry to hear that! :( :( :(

I hope someone can learn from this...

Damn mate, that is realy :( :( :(. I don`t know what to say, damn.... damn... damn...... :( 8rda+ rest in peace :(

For the people who are planning the Vdd mod. Don`t go higher than 1.85 Volt or lower than 680 ohm. Cool your chips with a good airflow, I think 1.9 Volt is realy the max (like 550/600 ohm) <<< BUT THAT IS OVERKILL!!!!

Sorry to hear that RB.

Well at least you got to enjoy your 8RDA+. Mine was dead after 5min of playing with it today.
5 minutes !!!

Just tried for maximum cpu overclock on the mobo. nothing froze.. straight: BiosRom checksum error. when I went to high.
=> Biosrom chip is fubar. if i can't get a replacementchip it's good for the bin too.

Sorry for the Epox fanboy's but something like this would never happen on an abit. Abits freeze at post; power down, clear cmos and everything is fine.


My first Epox OC experiance was verry dissapointing. :(

Btw, it just hit me but If you aren't going to try to rma the board or can't get it rma'd may I have your bios-chip???
I know it's a lame thing to ask, but it would save my board

Entus, if can get to leuven before Monday, you can have my bioschip.

Can you have a replacement for my board? It looks fine. :D ;)

Hmm, that`s a pity for you :( I`ve had in 4 years like 4 epox boards (kt133-266-266a-nforce2) and never had problems with ultra high settings. I think it`s just bad luck for you.....

Well I must of had that bios checksum error appear about 5 times already since I got my board and as yet it has not failed on me ;)

Also when it does appear I just reset the PC and hold the Insert key down and it fires straight back up :D

Hmmm, I'll have to give my board a visual when I get home later... I'm running at 2.0Vdd. Yikes!... Hey, what is the warranty on these boards anyway's? I guess if it fry's, screw it, this one requires too much Vdd anyway for high fsb. I wouldn't mind trying another one.. Maybe a V1.1 board.. :p

Are we talking about the same checksum error?

There are 2; the usaul post and get checksum error. And the Bootlock Bios Rom Checksum error. (no normal post; epa logo or anything) meaning a dead bios :(

unlucky Richbastard, hopefully you can live upto your name and buy another :(

I started a thread on AOA in your honour
http://www.aoaforums.com/forum/showt...threadid=12995

Can i ask if you used SMG grabbers or solder ?

Dude that sucks... :(

You can't be serious? :confused: I'll guarantee you I can fry any other brand board just as easy as an Epox when dealing with overvolting via Vmods.

Indeed, playing with Vmods is like playing with a loaded gun, Don`t do it ;)

This could happen to every mb....

Agreed, anyone who ever played with a kr7a at high FSB knows the meaning of dead BIOS. TG for BIOS Savior :)

Yeh, like my BD7II that stopped booting all of a sudden, then when I got it to work by leaving battery out for 3 days I can't OC for §§§§, and it's not the CPU I tried that already. Then 2 IT7s that blew on me (it's happened to several people). Yeh they're Intel boards but it's not like Abit is any better, at least I didn't do any mods and push it too far. What about the bad caps Abit used...I don't care who else used them, but Abit used them too, so they do do things like that.

Other than that I'm sorry to hear about that, hope you have better luck with your new BIOS chip :)

Dont you just love the term fanboy, were obviously Epox fanboys but ive never in my life seen an Abit fanboy. One can only wonder why.

:P

The bleeding edge.

What resistor will give like 1.80v for the vdd?

680?

About 750 :)

Im using 820 Ohms for 1.77 - 1.79.

I think the limit should be in the 1.80v range. 1.85v is the tops, but I'd still stay with 1.80-1.82v

First of all I'm not an Abit fanboy, I'll take whatever is best at the moment. Currently it's the 8RDA+ simple as that.

I didn't mean about killing the board due to Vmod. I meant about killing the bios just by raising cpu speed. Going from 1 bootup without errors or freezes to a slightly higher speed giving a direct biosbootlock, not a usual freeze at post or something.
I realise that posting my story in RB's vmod problem has caused some misunderstanding.

Unfortunatly bios problems seem to be a Nforce2 thing :( later bioses seem more stable now.
And offcourse I was a bit pissed off when posting this as I had a piece of new hardware that only worked for about 5minutes :)

About the Abit vs Epox thing. This was just my experiance in overclocking with both boards. Abit's freeze @post when gently pushing your cpu to far. The epox didn't, it just went from good post to fubar bios :( that's what I was supprised of. Not getting any warning/ heads up.

Hoping not to have offended the Epox fans.

You can get a new bios chip (pre-programmed to the bios level u want) from BadFlash.com...

More details in that

If you get a no boot situation, power down reset Cmos before going back into Bios as I found out the hard way, if you just reboot and go straight into BIOS if it freezes on you in BIOS in all likelyhood you just corrupted your BIOS chip

Not always like this but it's always good to know...Have you tried booting from a floppy and reflashing the bios - sometimes this step works when u think ur bios is gone south...

--fibo

Sorry to hear about your 8RDA+. I'm about to get one and I'm just wondering, I thought the VDD went to 2.2 in bios? And the Vmem goes to 2.9 in bios? If that's wrong, what are the volts?
