Hello people,
I've recently build a new rig:
CPU= ---------------- i5-4690k
Motherboard= ------ Gigabyte G1 Sniper z87
RAM= --------------- 2x4GB Gskill Sniper 2400 CL11
PSU=---------------- XFX Pro 850w Semi-modular
Cooler= ------------- Hyper 212 Evo


I've not tried to overclock yet (haven't had the opportunity), but I've put the CPU through a short session (about 5 minutes) of AIDA64 stres test, set to Stress CPU, Stress FPU and Stress Cache. Temperatures were really good, all cores around 45°C +/- 2°C (Ambient temperature was probably around 20°C).
But what really surprised me was the CPU Voltage, as it was always around 1.09-1.10 (it actually didn't reach 1.10). I looked at the BIOS setting, and it was set to AUTO = 1.095 if I remember correctly, which matched the voltage at that time, according to BIOS. I've read everywhere that stock voltage usually is 1.20-1.25, and that AUTO settings tend to set the voltage even higher, especially during a stress test. Therefore, I began to think that this was really weird.

So, is this true? Is the cpu voltage really that low?
Is AIDA64 reliable when it comes to measuring CPU voltage? Could it be a wrong voltage reading?

Well, just let one of us know and I'm sure myself or one of the many other members here would be more than happy to walk you through it or point out an excellent guide for doing it manually. Just keep in mind that not everybody who jumps in on these threads is fully or accurately knowledgable about what they are talking about. Any of the moderators should be 100% reliable and many of the members too. If in doubt, check badges. Obviously that's not a proven indicator of expertise but anybody with a lot of expert or authority badges is likely to be at least somewhat knowledgeable and most members with Legacy badges in addition are almost certainly so.

With turbo boost and power management features enabled it probably wasn't ramped up to the same level it would be under full or even near full loads. If you disable those features and change your advanced power settings in control panel under processor management to a minimum setting of 100% you would see a difference that would likely be nearer to the 1.25v spec. It's nothing to worry about. If you were overclocking I'd be worrying about stability at that voltage.

Turbo boost wasn't working, as all 4 cores were being used at 100%, and even the FPU and cache, so power management features shouldn't have been working as well... According to AIDA64, it was at full load during the entire duration of the test.

And I know it's not wrong to have lower than 1.1 at stock speeds, I'm just surprised witht he fact that it was automatically set at that number, and didn't ramp up even at full load o.o
Is that normal?

I just want to make sure that I AIDA64 CPU voltage reading is reliable... Or should I just get another voltage reading software?

You might check your bios version against the most recent available version and upgrade if a newer one is available. There could be a revision to the newer firmware that addresses voltage profiles. You might also change your power settings to performance if they are currently set to balanced. Of course, this might defeat any power management schemes designed to limit thermal issues too but with the low TDP of that cpu I doubt it.

The BIOS is updated to last version, was updated last week as a matter of fact.
I just want to clarify, I'm not getting any kind of problem or instability. This is not a problem, just a doubt. I just want to make sure that the readings aren't incorrect.
My power settings are set to performance (windows 7 64bit).
I will check to see if there is any kind of power management active and disable it. I will need to do that anyways, since I will be overclocking.
Unfortunately, I won't be around the PC until next saturday ._.

Ok, thanks!

I will probably be asking a lot about overclocking when I get my chance, too.
I have read a lot, but it would be my first time really overclocking, so I'm sure I'll have a lot of doubts...

I'll report back with the results as soon as I get a chance.

Thanks!

1.1v is actually quite a bit on stock speeds. 3.7ghz turbo on 4 cores, my I7 4790k at 4ghz on auto setting takes 1.08v. You also have the lastest bios version, which fixes putting in too high voltage on devils canyon chips.
But in your case, theres really nothing to fix or worry about. 1.1v vcore is not little (I'm sure 1.0v should work on 3.5ghz easily) but not too much either.

The thing that seems strange to me are 45c max. temp during stress test. Thats really low for a 212 evo. But thats mostlikely just Aida, I found my cpu to not go past 63c on aida but reach 95c in prime.

I have the stock i5-4690. (Not the K version.)

In BIOS I read:
CPU input voltage = +1.776v
CPU core voltage = +1.077v


However in CPUID Hardware Monitor I read:
Vcore = 1.776v - 1.792v
Vin3 = 0.136v
Vin4 = 0.272v



Basically Vcore in HWMonitor matches CPU input voltage in BIOS.

If you can make any sense of these voltage, than I hope it helps someone.

However I am confused as why my readings seem to contradict. Vcore in HWMonitor, I would have thought matched Core Voltage in BIOS. Instead it matches CPU input voltage in BIOS.
