@74Eric74 I ended up getting the H70, These chips sure are cool, on idle it never goes more than a few degrees over room temp. And stress testing it, it never goes over 35c om full load so im good to go with the overclock.
@mrfuzzer1 You’ll be fine with an H50
These chips don’t get as hot as the other i7′s from the 1156 and 1366 sockets.
sounds like Sonic the Hedgehog music
@Mirmidon87 Is it in idle? or is it being stressed?
@Mirmidon87 It runs to the speed you NEED. If you’re just browsing internet etc. your CPU will down-clock to save energy with no noticeable affect on performance. When you open your game, the CPU will ramp up to 3.3GHz, then your turbo mode o/c.
@Mirmidon87 i think that the cpu under clocks itself when there is not much going on change your window power settings to the highest and then it run at the 3400 mhz speed
Nice,im going to do this build but with 4,5ghz i think. Do you think a Corsair h70 will work fine for that or would you rather go with Noctuna Nh-D14? Those two are the once im thinking about
why did he disabled the CPI C1E?? what it’s for? to stabilize the cpu when overclocked?
@Mirmidon87 that’s because of intel’s speedstep technology… when the cpu is idle the multiplier will go lower to save energy, but once you introduce a load the multiplier will go up go 34
you can disable this setting in your bios
@Mirmidon87 Its because it automatically reduces the clock speed if the cpu is not under load. Try running the cpu at 100% load and then check CPU-Z
@Mirmidon87 its idleing at 1605 mhz. open up AISuitell and look at "monitor" then "cpu frequency" watch as you open up a program or web browser or something, it will jump up to approx 4300 mhz. if you play games it will go to 4300 mhz. its just the power saving mode. disable this in bios if you want.
can somebody tell me if there is something wrong with my core i5 2500k default core speed ??? I ran the CPU-Z software and it says that my default Core Speed is @ 1605.x Mhz, and the multiplier is x 16.0…..shouldnt this be around the 3400 Mhz with a 34.0 multiplier ??? I havent messed with overclocking btw or anything like that…
Thumb up if u muted!!!
Run Flight Simulator X on that man if you too busy and fly high with all add on set on suppppppppeeerrr high setting and download a PMDG Boeing 747-400 with weather reader on high detail and Ultra high XXX high::)
I thought it was dangerous to take intel CPUs over 70C?
I still have to reach the 5ghz mark. But don’t want to go through bios and also not wanting to disable the power saving mechanism. Highest I’ve ever done has been 4,9Ghz but that was on another mainboard.
At least mine won’t be running at 70°C o_O
@POPCORN454545 he set cpu voltage to 1.350 and the 1.7 was PLL. The chip voltage was 1.412v at 100% load.
Someone has got a hand picked chip or a engineering sample if power draw at 100% is under 1.4V. Almost all require 1.4+ volts for 100% load at 5GHZ.
The sweet spot seems to be 4.7ghz @ 1.345v and 1.368 draw at 100% load for 2500Ks.
you definatley coulda used a lower voltage…1.7 is high even for 5 ghz…mine at 4ghz and 1.45 volts…granted its an older chip but…eripjhdfg i dunno…really dont need 1.7…im thinking 1.55 or 1.6 woulda done it…try to eliminate as much heat as possible…longer life span
@TheGlobalflight 4.7
which air cooler do u use??
Is it stable with this much over a long time…. and what do you think is the best for stable long term use 4.5 or something like that?
@nawaz2kx Yes , you only overclock the turbo mode , when u go ino a game , it goed to the overclocked settings
@Darthkeyblader13 lol, if its only at 1.35 then keep goin man!
@ImperviousMason 1.35 is too high? i thought it was aight
@Darthkeyblader13 You don’t want to over volt your cpu, even if it is stable at 5ghz it may take a ton of power to do so, shortening the lifespan of your chip. You should establish a voltage range imo
