I don't believe that's entirely true. Based on two things. Number one, the fact that when you lower the voltage, less wattage is consumed. As you no doubt know, Wattage = Volts X Amps. So evidently, as the voltage is lowered the current stays the same, rather than rising.

Two, when you overvolt, the current to the CPU doesnt drop does it. It stays the same (i think), otherwise we'd find the CPU running colder when we overvolt because if as you say they are inversely proportional, then that would hold true. Because it is certainly current that causes heat rather than voltage, hence why Power lines run 10,000v through them.

I imagine your thinking of what happens with a coil transformer. Lowers the current by raising the voltage, and vice versa.

:D So all we can learn here is: Always try to overvolt Ya board...... :hrhr:

What PSU do you have, do you have UPS or surge protection?

i know this kind of information everyone wants to know:

i just bought a brand new power surge protector, like 4300 joules rating; plus i have a whole house surge protector installed.

as for the power supply, a brand new OCZ 700W SLI ready gaming supply.

you know, I would think you could over volt the cpu using Vcore but, ut-eh!...they figured out a way to give you under/over volt everything else but the darn Vcore!;)

EDIT:...actually, i think you could undervolt the Vcore.:)

It's been three years since I did my physics A-level but this is what I was thinking!!!

Current remains the same, the only variable is the voltage here which we manually change. Remember, IVy Watts is a Powerful lady!

One thing I will say, it's more resistance to the current that causes the heat, rather than the current itself but there is a direct link - just being a bit pedantic. :rolleyes:

the only thing i have learned from all this, is that if foxconn started selling toilet paper tomorrow i wouldnt buy it.

I guess it is possible . A frind of mine did a RMA of an Asus 7800gt that blew up due to bad heatsink contact with the core ....and yes , it had a huge burn mark :) . I think as long as they believe you don`t kill it by yourself it is possible to RMA ...who knows ?

PS : Sorry for your board :( . Burned silicon really sucks

i am going to call newegg and describe what happened...i will either ask for a full refund or get credit for another purchase...they have been very good to me so far and i have been a good customer for them.:)

Ohm's Law, it takes 1volt to push 1amp through 1ohm of resistance :)

Ohm's Law
For many conductors of electricity, the electric current which will flow through them is directly proportional to the voltage applied to them.

hmm why would burn marks affect anything?

The board was faulty, therefore you are bound to end up with burn marks at some point or another. Just because it has burn marks doesn't mean that it was user error...

:D

i am debating with myself whether i should tell newegg that it caught fire...they have a "no return" policy for physical damage...i presume they are talking about what i do to the board by making a mod...i do not think they are referring to physical damage caused by Foxconn's design inadequacy.

to be safe, i will just tell them that the board quit working after about 10 hours of operation and leave it that....telling them that a fire occur makes it sounds like i did something wrong when we all know this is the "YUGO":D of motherboards!

The only Fireconn board I had was a s754 board - the onboard sound never worked & the onboard USB gave up a few weeks later; it hasn't burst into flames, but its definitely a YUGO. GL with the refund Ace.

newegg is super in my book..they gave me a full refund....of course, i didn't say it caught on fire...LOL...i just told them it stopped working.;)

if the wattage is to remain the same, if you lower your voltage, the current MUST increase to perform the same amount of work. Wattage is a unit of work performed... if you have a 100 watt lightbulb, and you want to get 100 watts at 100 volts, it will take 1 amp... if you want to get 100 watts at 50 volts, it will take 2 amps... if you half the voltage, you must double the current to get the same amount of work done. Simple electronics.

BUT YOU ARE NOT GETTING 100 WATTS AT 50 VOLTS when dealing with CPU's !

Why does everyone keep overlooking the TOTALLY OBVIOUS ?
Overvolt a CPU, wattage, heat goes up.
Undervolt it, wattage, heat goes down.
This output is even listed on Intel's webpage.

If this did not apply, as everyone else said, if you overvolt a CPU, it should get cooler. Right?

When you lower the voltage to a CPU, the WATTAGE DECREASES. It does NOT REMAIN THE SAME.

I don't know if this applies to the other circuits on the motherboard.
If your above statement is ONLY for motherboard power components, then i"m wrong.

good to hear Newegg gave ya a refund :)

I got a RMA for the board before it even got to my house, held on to it for a
few days to see if any new bios where coming out to fix the Vcore issue ... soon
as I saw this thread I tossed this POS board in the mail on its way back to the Egg.

EXCELLENT decision on your part!:clap: ...no reason to have a frustrating event with the Fox(fire)conn:eek:

Yes, but not many circuits use a constant power supply. This is a constant voltage supply. It is not a question of more current to make the same power, it is a lowering of total power, but a shifting of power from one component (chip) to another (transistor) many times.

i see your point...i just lowered the voltage so it should have produced less current...my question is that how does that affect other circuits which rely on a power circuit that is now putting out less power?
