What temps are the system headers based off of? I plugged in a pwm fan and it didn't appear to ramp up when I launched prime so I would imagine that its not the cpu temps.

I hit 4.6Ghz @1.284V (more than the 1.272V under 1.25V + PLL Overvoltage under Prime) Prime95 for 14 hours, when I woke up MS Windows said Easytune6 (ET6) crashed but Prime had no errors and there was no BSOD.

I had OCed manuallly via BIOs and EasyTune6 wasn't open. I think EasyTune6 was running as a background process.

So is it stable (and EasyTune6 is just buggy)? Or is it unstable? AFAIK Easytune6 doesn't go up to 4.7GHz at <1.3V.

edit: will run OCCT for 2 hours w/ LINPACK later

EasyTune6 is garbage.

Happened to me with Easytune6 but didn't affect anything else.
Check your Event viewer's Windows logs, system tab. Look for WHEA errors...Probably it's stable and nothing to worry about biggrin.gif

EDIT: Easytune6 is NOT garbage, I like it more than Tweak Launcher for certain things, both have their uses.
Software overclocking can be a great tool if used right. thumb.gif

This has evolved into a huge frustration for me! I invested in three new premium 4-pin fans with PWM control capability, and plugged them into the 4-pin PWM headers on the UD5H motherboard. Firstly, they spin at full speed no matter what the BIOS setting (standard, silent, custom at all values). Secondly, EasyTune6 only slightly adjusts the SYS fan speeds down, even with the most extreme plots on its graph -- and the application crashes on its own (Windows 7 64-bit) consistently within an hour or so of doing nothing. Thirdly, HWMonitor Pro and SpeedFan simply do not control PWM fan speed, period, even though they are advertised to be capable of it. Fourth, and worst of all: there is not a single fan controller on the market that controls PWM fans with 4-pin connectors. No joke!

The fact that there is no demand for these minimum requirements, from a fan controller to a firmware fix, suggests that hardly any consumers spend the time to figure these things out (far from rocket science)!

I'm controlling my Arctic cooling F14 fans which are 4-pin pwm fans using a lamptron FC4. Its just a standard rheostat.

For some reason, i'm not stable anymore.... also, my temps are going sky high now, hitting almost 90, didn't change anything on my stable oc profile. i'm even not passing ibt on factory settings. ***?

I'm guessing ambient temps changed. I have the same problem when ambient temps rise past 25c, I use my 4.4ghz oc profile then. Or my power saver 4.2ghz offset oc.

wish you had the same cpu as me. would like to take a look at that 4. profile of yours.

edit: i even did went back to the f7 bios to see if would get beteer, but nothing changed. Also, i would like to know more about this offset thing.. I'm a first time intel OC, all my life i had AMD cpus, this is my first Intel EVER!!!!, So you could call me a NOOB. tongue.gif

Offset voltage is an extra vcore that applies under load, over your VID value. It helps get some power savings when idle, not applicable if you fold 24/7 for example...It's harder to stabilize it than regular fixed vcore/clocks setups.
