i7 860 core voltage 1.672 and 1.686

[darkaria]

I have a HPE-170T

Using CPU-Z
Core Voltage: 1.672 ATI radion 4850 460W PSU Orignial

Core Voltage: 1.686 Geforce 460GTX MSI Cyclone 650W PSU Upgrade

I noiticed a few weks ago my CPU temps were getting abit high, 35-40C idle and 60-70c under heavy load. I thought it was because of the ATI Radion 4850 1GB card I had. I normly gets 70-80c during a heavy load (by design it seems). It makes the bracket area and mother board area aorund the PCIE slot realy hot so I thought this might be filtering down to the CPU some how. So I bought the Geforce 460GTX MSI Cyclone 1GB because A. It is 10-14c cooler, and b. It will fit in on my motherboard do to a badly placed motherboard heatsink. However I am still getting the high tempatures. This is a HP OEM BIOS. There is no options for changing the voltage rating. I used Real Temp and saw my GHZ getting to 3.3ghz at times. So my HP has turbo mode on by default? Real temp can disable turbo mode but I am still getting the core voltage of 1.672 or 1.686. How can I lower the core voltage to safe lvls if there is no option in BIOS? I know nothing about overclocking.

Your computer will be fine. Software has problems reporting correct voltage, and I can guarantee you that your processor is not running 1.672 at stock settings. Its probably something close to 1.2v.

60-70c is decent as well and I would not worry about these temperatures. Modern processors can handle temperatures in excess of 100*C for years on end strait when running under default settings. There is absolutely nothing to worry about unless your computer is throttling or unstable.

Please show a screenshot. These numbers are unlikely, at 1.672 volts i7s will fry quickly.

Those CPU temps are ok.

CPUz is wrong. It has been wrong in the past, its wrong now, and it will be wrong in the future.

Either CPU-z is wrong or you will be needing a new CPU very, very soon. The threads I have seen where ppl have run i7s at 1.6 volts+ report them dying in a week or less.

Those voltages will definitely destroy your cpu quickly. CPUz has been wrong but that cpu has been out for what, 2yrs now? It would be highly irregular for cpuz to get it wrong on a part that has been out for so long.

I can still get it to say my 920 is running a 22x multiplier

I have no idea what to do then since my HP BIOS has does not include any abilty to change the voltage.

There is no reason to worry about it. You don't have any reasonable control over the situation.

Lets for example just say that you have an extremely defective motherboard that is feeding your CPU 1.686v. HP isn't going to take it back until something is actually broken so you are just going to have to sit out and wait.

I find it incredibly incredibly unlikely that this is the case however. 1.686v degrades processors under even a few hours of LN2 cooling;and, unless HP decided to include a phase change or a sweet water setup, you would not be seeing 60c-70c load temps. No air cooler available today would be able to keep that massive amount of current at a reasonable temperature.

I would also be incredibly impressed if an OEM HP motherboard could handle 1.686v without losing stability. Whatever engineering team gave the okay for that board to be included in your system should be let go. Completely over-engineering something like that would be costing HP a few bucks for every system they sold, unacceptable.

All the signs point to CPUz being wrong, its nothing new and happens all the time. Go look on XtremeSystems.org where they have screen shots of CPUz showing a x56 multiplier on a 920 doing superpi runs at 12Ghz.

Your CPU is running at 1.25v or less

I am wondering if applying Artic Silver thermal past would realy help much to reduce the tempature. I also spiked to 79c just a while ago. I am starting to wonder if my CPU fan is dying. I sent my HP in about 5 months ago because the on-board video died and took the pcie slot with it. The work paper came back and also the CPU fan was replaced as well. What is a good speed for a i7 860 fan to be spinning? The only heat issues I have delt with in the past only involved new thermal paste, and a good fan and heatsink dusting to fix it.
