i5 processor always require voltage increase?

[mxnerd]

In the past 2 years I bought 3 Intel motherboards and 3 CPUs

2 Z68 (ASROCK and Gigabyte) and 1 Z77 (MSI), one i5 2400, one i5 3470, one i3 3120

I found that I always needs to increase CPU voltage by 0.02v, or the system will just randomly freeze or bluescreen. I just can't use default auto voltage. i3 CPU seems OK though.

Sometime it will happen once or twice a week. Sometime it will happen several times a day.

I wonder if it's a common problem across sandy bridge and ivy bridge CPUs? All motherboards have most recent BIOS.

It's really frustrating. Anyone have similar problems?

I don't overclock at all.

Even with a mild overclock, I can run stock/auto voltage with excellent stability. What kind of power supplies are you using?

I would be willing to bet I could run on auto voltage at stock speeds. But that would just be silly. :biggrin:

At first I also think it's probably the power supply, so I purchased 2 new power supplies, Corsair CX430, COOLER MASTER GX 450W in the past 3 months, I even bought new power strips.

I swapped about everything, RAM module, power supply, motherboard, CPU, but it all comes down to the voltage problem. As long as the CPU voltage increased in the BIOS, the system stabilized, even with cheap power supply like Coolmax.

I only have one i5 on a Z77 board and have not had this issue.

 

[Ayah]

I have a 2120 on a C202 and a 3220 on a Q77 and both are fine at stock volts
I don't see why an i5 would be any different

Didn't see this happen with i5/i3 personally. Are you running any specialised apps?

What sort of memory are you using? Did you try raising the memory voltage instead of the cpu in your testing?

I never tried to increase DRAM voltage.

The only special program probably is VMware workstation. But it still freezes when I was not running the program.

The major system I was running begin to freeze up last week, about twice or 3 times. 2 days ago it starts to freeze up as many as 5 times a day.

I swapped the Corsair power supply with Cooler Master and it does not help. The system freeze up in an hour.

I replaced with inferior Coolmax PSU and increased CPU voltage, and the system hasn't freeze up since.
