Now I've been using well over 1.4V on the CPU/NB, is that dangerous

post #1 of 5

Now I've been using well over 1.4V on the CPU/NB of this x3 740 unlocked to a x4 40, is that dangerous

Currently I think its at 1.471875 Volts

the CPU is at 1.45

so

310x12=3720 CPU
310x9=2790 CPU/NB

to get a ~3h30m prime95 fail on the 2nd core, which is the weakest, I had

1.471875 V cpu
1.45 V cpu/nb

so I lowered the CPU volts, and that has the biggest effect on my socket temps (no core temps on a unlocked x3 740) and upped the CPU/NB volts, haven't prime95ed yet though

But previously people have said over 1.4V isn't needed, but it is for this chip, I have seen the stability from using over 1.4V on the CPU/NB

So how dangerous is that???

You're fine on CPU-NB, though it's a lot of voltage (often you never need over 1.4V) but safety-wise/longetivity-wise it's fine.

Solid

and thats no mistype on the volts

CPU is 1.45V
CPU/NB is 1.471875

I did a quick p95 test for 1h25m, I will try a 10+ hour test when the dirty bronfmann booze runs out....

1.4 to 1.45 is fine for 24/7. just prime95 blend for 2-4 hours and use it. you'll know when its not stable. best way to know if its stable is to just use it on a day to day basis, no need to stress out your cpu more then what you need. unless you fold 24/7.
