Damn that sucks :-(
whats your mobo and PSU...got that aux. 12v line??? (ie abit nf7 with an antec PSU)
I'm hoping when i get my 1700 later this week that the alarms that go off when i up my vcore go away (that is i hope i screwed up my CPU)

my psu is the "came with the case" 300W generic. my mobo is the abit kd7, and its does have the extra p4 12v power connector. im not using it though caause my psu dosent have it.
it worked finewith my jetway and 2100 pali.

i shouldprobably turn it off.

just doesnt make sence to me...either way you should really upgrade to a name brand PSU if you want to have a "safe" overclock
damn it gets confusing! looking at your ava's been the same! sometimes it makes me think your all talking to yourselfs! lol!
If it doesn't go away with a better psu then its not a problem with the psu!

Come on man, you should know that a generic PSU is junk for overclocking...now get your wallet out and at least spend around $35 and get the 350w Fortron from Newegg.

That is your negative 12v rail you are talking about right? Well I wouldnt worry about that because firstly readings for negative rails are always inaccurate and secondly this is only for data communication anyway.
He said it was the +12v rail. I would head over to newegg and get yourself an Enermax, Sparkle, or Antec PSU if I were you...

No, he mentioined explicitly -12V rail as shown below.

:eek: opps. Sorry bout that...I wasn't really paying attention.
What are the negative rails for anyways.

I would run prime95 for a couple days and if there are 0 errors.... turn off the alarms :D.

it worked finewith my jetway and 2100 pali. KD7 and KD7-E are very finicky about power. The +12v (four pin) connector is an absolute got to have. Be very careful with that board. The bios will freak out on you if you don't get it right. I have two KD7-Es right now that won't boot at all. Both were tried wth the same PSU (Enermax 365) and niether will boot at all. This is with the +12v connector installed. Search the forum about this board. There are a lot of posts about it.

well, I turned it on for a while and everything worked fine. no i dont have that extra power connector :( And yes im talking about the negative 12.
oh, btw, I booted into windows error free at 2.3Ghz on 1.55V :eek:
If i can do that, should i just turn off the alarms and act like normal?
In the pc health status thing in the bios, there is no thingy for the -12V. In the monitering software that came with the mobo, there is no monitering for the -12V line. only in the old monitering, and mbm5 is there monitering on the rail, and alarms. because all the mobo stuff dosent moniter that rail, could that be normal? anyone else have this problem with the KD7?

OH!!!!!!! i just thought of something !!!!!!!!!
one of the leds on the mobo lights up orange whenever the power strip is turned on. could orange mean "trouble with the power?"
yesterday i also smelled a burning smell. At first i thought, "oh s***" but my temps were all normal 45°core 35° surface. so then i thought it was coming from my power strip. but im not sure if it was the box fan or the power stip.

ignore it, some of the stuff in mbm5/ anything else is iffy.
The only ones you should be looking at are the +5v,+12v and the Vio(3.3v)
i was alarmed too when i first installed it, but i dont believe it, i have no stability probelms with my oc below, and im only using a 300w psu. (atx2)

so you have the -12 volt problem too?

I think ill just ignore it.

ignore it if you wish, but that still doesnt change the fact that a 300watt (gennerally over rated) generic PSU is a no no in the overclock world

ignore its, its a bug, not a hardware issue.

Like I said -12v readings are unpredictable and it is only for data communication anyway. Just forget it!
You seem to be skippin over alot of the posts... Worry about positive rails .. forgot the -12v and -5v because they don't report those right.

That is correct, The neg allways seem to read off, but the Pos is the main concern. Why the alarm tho? Most mobo alarms have a sequence of beeps that are described in the manual. If ou dont have a manual, you can download it from the man. website. BUT! I have had it with cheap PS's! Even the 300w that came with a case I bought had a true voltage reading of 4.85-4.92 on the +5volt rail and a 3.2-3.25v on the 3.3!!!! That S%#^s!You could even hear the fans slow down when the proc was put on a full load situation. I learned my lesson here and just got a 400w antec and the voltage seems to be exact and steady no matter what the load. I also in case you looked at the sys we got, the pelt is powered by a second meanwell power supply designed to power our 226w peltier. So at no time have we put that task in the hands of our sys ps.
Have a great week and thanks to all for advice and tips!
