Too low voltage harmful?

[grandpatzer]

Hello

I recently started tweaking my 2500k and found out by Enabling PLL Overvoltage, LLC to 75% and putting CPU VTT to 1.20v (default was 1.10v) made me achieve above 4.4ghz speeds.

I'm currently testing 46x * 100 = 4.6Ghz, Vcore Offset +210mv gives me 111GFlops (Linpack with AVX).
But I'm experimenting undervolting and so far Offset +180mv gives me 110GFlops.

Now I would prefer lover voltage but is there any way that CPU gets harm with the fact I'm getting 1GFlops less thus the voltage might be slightly too low.

So, I could leave it at +210mv and Linpack reports 111Gflops.
Or I could leave it at +180mv and Linpack reports 110Gflops.

My next step is trying out +170, +160mv.

I might even aim for 4.7-4.8Ghz problem is that +180mv gives me 75/82/85/82/85c so Hottest core after Linpack is 85c.

Running the cpu at a lower voltage will not harm it in anyway what so ever. Running it at a lower voltage will decrease you temps and make it more efficient thus making it (in theory). Last longer.

Lowering the volts won't harm, if anything it will save power and extend the life of the cpu, but there will be come a point where at 4.6Ghz or whatever your running at, the cpu wont have enough volts to run and maybe become unstable or pc may re-start, just need to find the lowest voltage point at where the cpu will run stable, thats all the fun asleast it is with x58

Harmful in the sense that it can cause instability. We all know that blue screens are bad especially when it all seems to be working fine, you could lose work and it's just an unconfortable experience.
It's not harmful in the sense that it migh damage your CPU, everyone knows that. As said above, temps will be cooler and your machine will live longer. That's a rule that is applied to ever electronic component.

Low voltage wont harm the cpu in any way, and as someone said already, it will make it last longer.

.... though blue screens can be harmful to the operating system. at worst you might create a fatal error and have to reinstall your OS. this is highly unlikely though.

i once read an article by a guy who undervolted his CPU and his brand new GPU, the $800+ Geforce 4 Ti4600 and tried to prove his system would be so cool he didnt even need to cool it.... and fried the lot. Later that same day... his super awesome Ti4600 was part of his keychain LOL

undervolting will be no problem, just remember you still need a fan on it.

Thats standard procedure! guy must of been an idiot haha

:lol: How can someone be so naive? I guess you need to be either a loon or wealthy enough not to give a damn , to do something like that :lol:

Yar, the funny part was the guy got really pissed off when the ti4600 fried. Why does the word 'moron' spring to mind? No, he wasnt rich enough not to care, as he ended up replacing it with a Ti4200.

He was simply trying to prive the point that undervolting reduces heat and therefore parts run cooler (but not so cool as to not need a fan, derp.)

What he proved was he was capabale of 'epic failure' lol derp
