i5-2500k cpu temperature

[dhamiltongrey]

Good morning,

I built a custom computer for myself with the following specs

INTEL I5-2500K
ASROCK PRO 67 SE MOBO
8GIG VENGEANCE 1600MHZ RAM
NVIDIA GTX 650TI SSC 1GB
850 WATT PSU
AKASA VENOM VOODOO CPU COOLER
64 GIG SSD - OPERATING SYSTEM ONLY
500 GIG - MAXTOR - PROGRAM FILES
3TB - WESTERN ELEMENTS - STORAGE

When i first installed the system i used the stock cooler that came with the cpu and my temps were at
37degrees idle and underload on prime 95 they sky rocketed to 90degrees plus
i recently purchased the AKASA VENOM VOODOO cooler and the idle temp has dropped to 27degrees and prime 95 peaks at 62degrees

my question: Is it safe for me to overclock this system to 4.5ghz and how do i accomplish this using the bios on the asrock board.. ive turned the turbo boost option on, but the CPU-Z is showing the cpu running at stock 3.3ghz - do i just adjust the multiplier to x45

Thanks
Looking forward to hearing your views
Kind Regards
David

When you had the stock cooler on, you must have not had it mounted solidly. Did it have TIM applied? Was it the correct stock cooler for the CPU? There's no way it should have allowed the CPU core temp to reach 92C in Prime95.
As far as the Akasa cooler, that is much better. I presume you are referring to core temps or Tjunction temp. Here is a refresher on temp terminology:
http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html
As long as you can keep the core temps below ~72C, you can OC.

Btw, here is what I use to work up my OCs with: http://www.techspot.com/downloads/4965-intelburntest.html
Much quicker. If it passes the default 10 pass run, chances are it is stable. You can verify with Prime95 over long periods if you want. Sometimes heat will build up over several hours and cause a fail.

thanks for the link, i ran the burn test on medium, 10 passes no problem, then high, no problem, the very high, no problem, but when i selected maximum on the second pass i got a BSOD... does that mean its not a stable system.. temps were peaking at around 70-74degrees

After reading the hundreds of posts on here.. ive come to the decision that overclocking while it has its benefits seems to cause more problems than it does solve.. i use 3ds max an awful lot which is why i went from the stock cooler.. my performance in games is outstanding. i know ill get grief for this but i dont care, i use a really big 50" tele thats over 10years old now and the maximun resolution is 1024x768 connected via the vga cable on back.. it works and i can see everything from the other end of my bed where i have a wireless keyboard and mouse.. i can play battlefield 4 on ultra settings and using fraps im getting a constant 60fps never dropping below or going above.. its silky smooth and when everything is going nuts with bombs and explosions its still at 60fps.. absolutely no need for me to overclock whatsoever.. so i think im going to stick to my stock settings, have a long cpu life and leave this overclocking in the forums... after 4hours of BF4 my temp reached 45degrees.. awesome!!

Lol... yeah, at 1024x768 you SHOULD be getting great framerates. BF4 while lying in bed on a 50" TV. Man. Is that livin' or what?

Btw, what's the native resolution of that TV? 720p? 1080p?

to be honest im not sure.. i imagine since its so old it would be 720p.. it does have a hdmi cable.. i did try that at somepoint in the past but it was too blurry..

in response to the link you sent me.. any thoughts on the maximum burnt test.. second round on the burn i got a BSOD..

Did IBT fail at stock speeds or after you OC'ed the processor. If you run the default 10 pass run and it fails, you have an unstable processor. I hope that wasn't at stock.

It's odd though that the HDMI connection was blurry. That should have been sharper than analog (VGA). Maybe because the HDTV is so old. But as long as you are using a VGA connection, try switching to 720p resolution. It might be designated as 1366x768 or 1280x168. Wide screen will give you much better gaming.

The turbo boost option was set to 4.4ghz
i ran the IBT at medium - 10 passes success
i ran the IBT at high - 10 passes success
i ran the IBT at very high - 10 passes success
i ran the IBT at Maximum - 2nd pass BSOD

I tried switching over to a higher resolution but the screen wont display it correctly, i tried everything to get it stay on the screen but it goes off screen at the edges quite considerably to the point where im having to guess where the mouse is.. the only resolution i can get to fit the screen is 1024x768

for overclocking, just play with the multiplier. stock is 33x. move it up to 40x and keep retesting with IBT set to maximum stress level. if you make it through, move up one multiplier to 41x. leave everything else on auto, dont change anything, even leave your ram at stock 1333mhz. keep moving up until you bluescreen, obviously your bsoding at 45x, sounds normal for auto settings. first you want to find out your max stock stable multiplier while using the automatic cvid voltage. find it and report back... also go download hwmonitor as you will need that later to watch windows reported vcore to compare to the cvid automatic voltage. later we can start either removing vcore to create less heat if your going over 80c, or adding more vcore to get a higher multiplier but staying under 80c.

also sandy bridge is not at all like ivy or haswell, it can take the heat and voltage much better than the newer architectures, 80c@1.35v vcore is nothing to sandy bridge.

My asrock pro 67 se motherboard is confusing in the bios, theres no multiplier option.. theres lots of voltage offset options and hertz increase options but i cant find a multiplier option..

cpu ratio? should be 33x. leave the turbo settings alone or just automatic.

when i get home from work i will go through the bios and take photos of all the overclock features so you can see what there is.. i think my motherboard is a bit lacking, but built upon a budget i must suffer.. i didnt have overclocking in mind when i bought it.. im also little bit annoyed with my akasa voodoo venom cooler, its perfect for cooling, but i was planning to run an sli setup in the future, this big box of fins and fans completely covers one slot up.. i even had to remove the funky casings from my vengeance ram.. boohoo.. oh to win the lottery!! hehe

I never run IBT at any setting other than the default. I love my processor too much. Besides, after passing the default setting, it has never BSOD'd or crashed a game. If you ran 10 passes at very high (!) you have a stable OC. There's absolutely no reason to even OC if you are gaming at only 1024x768 (?)... let alone take it to that extreme. Your GTX 650 Ti is your weak link, not the stock i5-2500k.

that makes me a very happy chappy indeed..
