Is 1.45v safe for a wolfdale?

[SlyReaper]

I've managed to get my E5300 stable at 3.8GHz, but it needs 1.45v to do it. Is that safe? I've heard stories about 45nm chips being damaged if they go above 1.4v. The temperatures are 60C on each core under prime95 small FFTs.

Edit: bah spoke too soon. Prime95 just threw up a rounding error. It needs even MORE volts. FFS

How much extra volts are required from you going 3.7 to 3.8? If it's loads more then I say it's not worth it as the extra performance you're getting is minimal.

It's pushing it a bit imo but they are all different, I would be happy with 3.7 from that chip tbh

Is that vCore you set in BIOS or actual vCore the chip gets while under load? (as seen in CPUz)

What temperature is it at?

I'd consider 1.45V at 50 degrees fine, but 1.4V at 80 degrees to be pushing it too far. As you may have guessed you're rather borderline here

Can you afford the £50 to replace it? if so fire away... if not I'd back off to atleast 0.1v below the accepted "safe" level...

My max was and still is 1.45. I've heard tales of severe degradation beyond it. Also that is a good clock for that chip, only 200mhz off my E8400

3.7 requires 1.4v. That's volts set in BIOS. CPUz reckons the voltage atm is 1.392. I never did work out why CPUz always disagrees with BIOS voltage.

 

[JonJ678]

Bios voltage is the maximum the board will offer to the chip.

CPU-Z is the voltage currently seen by the chip. Even 'idle' it is less than the maximum because voltage decreases with current and current increases with cpu load, and the cpu is never truely at idle.

The other issue is that neither cpu-z nor the bios is particularly well calibrated, and load line calibration which destroys all this by changing the bios voltage to a target rather than a maximum.

3.7 requires 1.4v.

and yet another 0.05v won't even get you 3.8ghz stable? seems hardly worth the effort trying to push it any further.
