Just built my PC, 4770K, CPUID states I am running at 1.760v?

Hi all,

After finding my purchase of cooler to have been incompatible due to it hitting my GPU, I built the system with the stock Intel to get me by.

Temps are not great, hovering around 39/42 idle, and earlier in the high 70's. Though system is reasonably quiet.

I have done nothing in bios but set my memory at 2400Mhz, yet, CPUID reports the CPU as running at 1.76v.

That can't be right can it?

System as below, running W7 64bit.

1 x Intel Core i7-4770K 3.50GHz (Haswell) Socket LGA1150 Processor - Retail £275.99
1 x MSI HD 7950 Twin Frozr III Boost Edition 3072MB GDDR5 PCI-Express Graphics Card **NEW REVISION** £239.99
1 x Samsung 256GB SSD 840 PRO SATA 6Gb/s Basic - (MZ-7PD256BW) £193.99
1 x Asus Z87 MAXIMUS VI GENE Intel Z87 (Socket 1150) DDR3 Micro ATX Motherboard £169.99
1 x Hitachi Deskstar 7K4000 4TB SATA 6Gb/s 64MB Cache 7200RPM - OEM (0S03356) HDD £163.99
1 x Seasonic X-Series 650w '80 Plus Gold' Modular Power Supply £119.99
1 x Silverstone TemJin TJ08B-E Midi Tower Case - Black (SST-TJ08B-E USB 3.0) £83.99
1 x Patriot Viper "Black Mamba" Generation 3 8GB (2x4GB) DDR3 PC3-19200C10 2400MHz Dual Channel Memory Kit (PV38G240C0K) £73.99
1 x LG CH10LS28 BD-ROM 10x BluRay ROM / DVDRW SATA-II Optical Drive - Black (Retail) £63.98
 
That's a good idea,

Have a look what it says in the bios, I'd set manually anyway. 1.744V would surely kill the chip wouldn't it? cpu-z must be wrong, that more like it in HWMONITOR.

If there is no fire in your case i would suspect cpuz to be wrong and hwm to be right. Try and re install cpuz and see if that helps but in any case you are fine because this happens a lot.
 
Firstly 1.76v would not be a problem for the RAM, yes you might not want to run at that 24/7 but it should cope without issue. If it were too high for the RAM it would just not boot.

I notice you have the ASUS board. Get the Asus software installed and use that to check the voltage.

I would also recommend that you set the RAM using it's XMP profile rather than just set the speed to 2400. This is done in the bios.

Are those temps at idle?

And if you put 1.7V thought that CPU not under LN2 it would be dead
 
CPUz 1.66.1 reads the wrong sensor on z87.
Tried it myself and it reads the voltage in not the vcore.

Use an older version till they fix it.
