High Processor Voltage

I purchased a DS Ode system last year and with the exception of a couple of small issues after receiving it it has so far been a great system. However, I was recently made aware of something which has me greatly concerned regarding long term stability.

In short, I showed the system to a friend visiting from out of state who has been a computer and IT specialist for years and he was impressed with it's overall quality until he looked at the CPU-Z stats which showed a v-core of 1.416v regardless of the system power settings.

He advised that the Intel maximum recommended voltage for the i7-4930k processor should not exceed 1.40v. He further stated voltage at that level could, and in his opinion, most likely would result in early failure even if the cooling system keeps temperatures in check. He even went so far as to say that a processor needing that kind of voltage to operate even OC'd (it does have a OC to 4.3 GHz) should never have been placed in a system.

I'm deeply concerned about this and wanted to post to get the opinions of others here and hopefully have my fears allayed that that it isn't as big of a deal as indicated. I've already had the system several months with no significant issues, but a processor failure is something needless to say I'd like to avoid.

I hope I posted this in the correct part of the forum and thanks in advance to everyone for taking the time to read and/or answer.

I will say that my experience with DS so far has been quite positive and I really like my comp. I'm just distressed at the possibility that my jewel may in fact turn out to be a lemon in disguise.     

Hi Wholly_Knight.

As a general rule most CPU Vcore voltages should not exceed 1.4 volts. There are a bunch of Over Clockers that run quite abit higher than that. Especially if they are going for high bench scores. It may or may not shorten the life of the CPU with a Vcore over 1.4. Conservative people may not want to exceed 1.38 or so. CPUs vary from chip to chip and what destroys one CPU may be no problem on another CPU. If you are concerned about your Vcore setting you may want to reduce it to 1.38 or 1.39. Your setting does seem a little high but DS must of had good stability at that level. You may have a chip that doesn't respond well to Vcore voltage and DS had to raise it to reach you 4.3 OC. Give DS a call and they will be glad to adjust your OC if you will be more comfortable with a lower Vcore setting.

Intel lists 1.4V as max on this link in section 7.4.

Notes:
1. For functional operation, all processor electrical, signal quality, mechanical, and thermal specifications must be satisfied.
2. Excessive overshoot or undershoot on any signal will likely result in permanent damage to the processor.



From what I have seen people are OCd to 1.37 to 1.42 and stable. My sources say it can be highly dependent on the chip its self, the BIOS and motherboard.

You are about 1% higher voltage which isn't very detrimental to the lifespan of the chip.
If it is a great concern you can try the 1.37V and see if it is stable. If it is just save the bios as profile 2.

1.399 Vcore and stable.

I really don't think the vcore is anything to worry about, but let DS decide and they will turn it down if you like. 

Stay in touch.

Lies, Bprat is OC God.
