i7 870

[Bone]

im currently Using This CPU Over I5 750

but is it Overvolted ? in stock CPU Settings No oc no voltage Option

it just hot as 80c above

so i had to undervolt i little abit now even gaming i had 73c avg

mobo is ASROCK p55de3

Which one do you have the i7 870, or the i5 750?

Also write down the volts you have for default, then work your way down by decreasing 0.10 each time you do a test with Prime95, or Cinebench, if you get a BSOD, go up by 0.05, until you stop getting a BSOD, or what you're comfortable with.

i7 870

when bios default it running over 1.350on stock [not sure] so i had to decreasing voltage on 1.17 and worked fine

That's pretty much all there is to it, get to a point you're stable and comfortable with. Also is this 73C when underload? If so, then I don't see a problem at all.

Ok thanks this is first experience that i had to undervolting cpu that running stock

Did you properly apply thermal paste? I recently replaced the old i5 650 with i7 870 using the stock cooler that came with Dell XPS 8100 from 2010. When I first booted, the CPU fan raced for a while, but then it quieted down and has been quiet ever since, even running Unigine Heaven at Extreme settings which works and heats my GTX 1060 a bit hotter than with the i5 (GPU peak 72-73C vs 64-65C). Maybe the thermal paste had to flow and take a set initially, then all was good with all stock BIOS settings (I have no voltage or speed settings).

At the same time I upped my RAM from 8 GB 1066 to 16 GB 1333. So with CPU and RAM upgrades I was able to up graphics settings significantly and see details in games that I could not see before.

PS: My i7 870 is at stock settings 2.93 GHz (3.6 GHz turbo). And it seems to idle at the same 1200 MHz as my i5 did. So idle power use with i7 870 and GTX 1060 is still around 50 watts. I installed a package in Linux to monitor temperatures and when running Unigine Heaven at Extreme settings with full tessellation, maximum temperature of all cores of the 870 was 66 C. Idle or with just Steam client running the cores are 31-33 C. My only case fan is the exhaust fan built into my PSU at top of case (not counting CPU and twin GPU fans that just blow air around within case).

Does overclocking run it at that speed all of the time, vs. SpeedStep which varies speed on demand? When I put my 116 watt GTX 550 Ti in an old PC I have with single-core (hyperthreading) 3.2 GHz Pentium without speedstep it uses more max power (and idle power) than brief peak power (and idle power) of MUCH faster i7 870 with 120 watt GTX 1060 (measured AC input).

Yes I have MX-4 Artic Thermal Paste and re applied with Stock Cooler and eventhough it ran up 90c at maximum

currently i just oced at 3.52ghz(which is safe bet for Stock cooler) with decreased voltage to 1.21

idle is 49c and fans most up to 2800rpm or 3200 its loud but it doesnt matter when playing with headset on

when load it ran 75c

Playing DiRT Rally, which takes advantage of up to 8 threads for different things, my i7 870 core temperatures did get higher: 78C 82C 77C 83C max for the 4 cores. I don't know how that relates to rated max T-case 72.7C. Maybe individual cores in turbo mode at varying times are allowed to get hotter as long as overall case temperature at the integrated heat spreader does not get too high. I did not have any issues at all (other than my skill and being up too late last night).

My GTX 1060 maxed out at 65C. When running Unigine Heaven benchmark, CPU was cooler and GPU was hotter.

For the sake of $15-$25 ppl can buy a 120mm tower cooler I don't know why they don't like the 212evo or Cryorig H7.

$15 lousy dollars ^ would give you piece of mind and much better cooling.

im not gonna oc that much by using that and

as far when I use 2500k on stock cooler and stock speed never got this hot as it

I slap after market coolers on stock cpus all the time they're quieter and do a much better job than stock coolers.

Maybe your stock cooler push pins aren't locking in right it's anyones guess why you're getting high temps.
