Unusual Temps with i5-3570k

bokbchoy · Jun 9, 2013

Hi guys
I just recently purchased an h100i to assist me in overclocking my 3570k
I followed all the steps and it looks like it is working from the outside perspective (the lights are on, fans running etc.)
i followed the steps here
http://www.overclockers.com/forums/showthread.php?t=693613)?
to bring my 3570 to 4.5 ghz
however, i am getting around ~40C on idle
and when i run prime 95 blend i go all the way to 100C for all the cores
Could you guys help me figure out why the temperatures are so high when i know the h100i is a great cooler?

What voltages are you using at 4.5Ghz? Please tell me you are not OCing via software, which is a bad idea.

Novuake :

i set the voltage to 1.35v
should i be setting it lower?
heres proof of the voltage from aida64

and i did not overclock using software

OK 1.35V is a bit high. You should find the LOWEST possible Voltage you can for 4.5GHz. For example I get 4.7GHz on 1.28v.
What LLC level are you using?

Monitor your max Voltages with CPU-z.

Novuake :

my llc level is on high since there are no numerical values in the asus uefi menus.
what voltages would you suggest me use?

Novuake · Jun 9, 2013

OK your LLC should be either level 1 or 2. So just under the highest. Try 1.24v and work your way up until you have a stable 30mins prime run.

Novuake :

i changed the voltage to 1.24v and now i am not able to boot into windows (startup repair)

Novuake · Jun 9, 2013

Startup repair? Thats weird. Should not boot at all. Try 1.26v.

bokbchoy · Jun 9, 2013

Novuake :

ok i set voltage to 1.26
computer booted fine
however when i tried to run prime 95 computer froze and blue screened
do you think it might be a faulty h100i?
this is my second h100i ive had, the first one having a bad sata plug.

Novuake · Jun 9, 2013

No, its a failed OC. Hmmm try 1.28v If that does not work something is wrong. Il send you a guide.

bokbchoy · Jun 9, 2013

Novuake :

yeah 1.28 doesnt work either
blue screens and gives me different errors each time
first time was sys32 and the second time was memory management

Novuake · Jun 9, 2013

There is something wrong. Follow this guide. http://www.thinkcomputers.org/intel-ivy-bridge-overclocking-guide/

What are your full system specs? Makes sure XMP profiles are enable in your BIOS.

bokbchoy · Jun 9, 2013

just a few clarifications
should i be running the cpu voltage on offset mode or manual
also how would i set up the xmp profiles
ive heard of those but i never got to find out what they were and or how to enable them
system specs are at the top

Novuake · Jun 9, 2013

bokbchoy :

XMP should be somewhere in your BIOS, just enable it.
Keep manual fixed mode.

Novuake :

what voltage would you recommend me start at now?

OK here : From one of my previous threads.

1. Disable all power saving adn turbo boost features and pick a load calibration, 1 being very stiff and one voltage constantly, 2 being a little more relax(easier to achieve stability), i prefer level 2.
2. Set voltage to fixed at first and drop it to 0.9v. (You can do this with stock cooling as it reduces heat generation)
3. Boot into windows and run prime 95 or similar stresstest to test for stability for atleast half an hour. This will give you an idea of how sensitive your specific CPU is to voltage change. (You can do this with stock cooling as it reduces heat generation)
4. Increase your voltage to 1.2v and multiplyer to 4.2GHz. Test thoroughly for an hour. Keep a close eye on temps with real temp or HWmonitor.

After that you can increase Multiplier one at a time testing for half an hour between each bump. When stability is lost, add 0.05v and try again.

Repeat process until you reach your desired OC or unacceptable temps(drop one clock and/or Voltage) and viola you have your OC...

DO NOT EXCEED 1.3V! Also keep temps under 90C under max load. Although if it touches over it its still fine. It will shut of automatically if it gets TOO hot(103C).

Ignore step 2 and 3 if you like.

Thank you so much for helping me.
Also as a side note, I finally realized how useful it would be to have a good ssd to help with the boot times XD
will now consider getting one

Well it improves general responsiveness too. So yeah its awesome.
