With my air cooling set-up I hover in the upper 70s with spikes into the 80s that do not last long. In the most recent test I did, the highest temp was 91 on one core, with the rest all 87 and under. My average temp ended up being 78 because the 80c temps occurred frequently enough to raise the average. Haswell seems to spike in temp a lot more often than Sandy does (just an observation that is totally subjective on my part). I can't wait to get some water flow in my case.

AIDA64, Prime95, Linpak, OCCT ? ..... I wouldn't do it under adpative...... under manual yes..... but I really don't see a use for that as I don't wanna run my system day in and day out at max voltage.

Asus has a fine little program that seems (so far) to be good at determining system stability under real\ world apps ....it's called RoG RealBench Ver2 and can be downloaded off RoG Forums.

My goal was 4.6 Ghz at under 1.4 volts and < 75C on hottest core with no reductions in other BIOS parameters. Finished build last nite.....but had to clear CMOS cause of a windows cant keep time issue so restarted tonite. So far ....settings as follows:

Multiplier = 46
Vcore Setting (VID) = 1.380
VCore (Observed) = 1.408 (1/2 second peaks to 1.424)
DDR-3 Speed = 2400 (XMP)
DDR-3 Voltage = Auto
DDR-3 Voltage Observed = 1.677 (bit hi for my taste)
Windows Power Scheme = Balanced
All other BIOS settings at defaults
Idle Temps = 30-29-28-27
Max Temps = 74-73-70-65
Water Temp In = 26.0
Water Temp Out = 25.6

Tried reducing the DRAM voltage but anything under 1.64 setting was unstable.

I feel like I am doing something wrong in getting 80-85 C range for Prime95 Small FFTs or 2nd round of blend (800000) at only 1.3 V. I did reseat my procesor and added in new thermal paste (Glecid GC Extreme instead of an old tube of MX-4) which helped reduce my temp by about 4 C.

The use of prime 95 on Haswell is shall we say "widely discouraged" by Intel and MoBo manufacturers..... and if ya on Adaptive mode, can be downright suicidal. While the MoBo manufacturer's say ya can go ahead and do it, **if** you use only the manual setting, since I would never run under manual for every day 24/7 use, I don't see the point. Due to the unnecessary heat and noise while under low loads, since I'd never use the system that way, I saw no real value in testing under manual. I frustrate myself enough with the trial and error time investment tuning my system for every day use smile.gif.

While I appreciate that many do enjoy it and I love reading about the results, to invest that time to say "Well I can do 4.7 under a setting (manual) I'll never use again" is just not something I'm willing to invest time in right now. So again, w/ all the manufacturers saying "No AIDA 64, no Prime95, no OCCT", I went looking for something that would stress the system to the point that I could reasonably be assured I won't experience crashes on a routine basis.

JJ recommended RoG RealBench in Asus' Manual Z87 Overclocking Guide on Youtube and I followed the threads on the RoG Forum a bit before trying. I even asked how folks found it compared to the "ole standards" and the responses both public and private were favorable, basically indicating that if ya "can pass RoG RealBench, you system is likely to handle anything ya can throw at it. This will be a production box (CAD) ....with off hours gaming fun on occassion of course:) ........... and I haven't been able to make it stumble as yet with the settings I obtained running RealBench

If ya wanna give it a try.

What is ROG RealBench?

RealBench uses real, open source applications to test your PC as it would perform in RL. Although it can be competitive, it's not primarily designed to be more hardcore and time consuming - it's a benchmark for everyone.

Select the three (now 4) tests and run the benchmark to get your result. Each test uses different parts of your PC subsystem, so all areas are covered. Share the result here on the forum to compare to others, or, compare to pre/post overclocks and pre/post upgrades to get maximum value from your PC.

By using open source apps there is absolutely NO ASUS-bias. Our focus is to offer a value-add to PC enthusiasts as a whole, by offering a branded tool to better evaluate your system, overclock and upgrade. Please share its existence on other forums to help others.

It has both benchmarking and stress testing mode.

BTW, the benchmark function uses the following in it's test suite ....

Gimp Image Editing
Handbrake h.264 video compression
Open CL using Luxmark Open CL
Heavy Multitasking (Combination of the above)....

Stress test applies a very high multi-tasking load.... way more then benchmark setting .... if ya gonna crash, the tough part comes at 12-15 minute marks.

The uncore settings are in the chart too. Only one person has uncore at 3.4ghz when looking at OC @ 4.7 or higher.

I was more interested the "no reductions in any settings" group ..... in how many have it running all out (at same frequency)

FWIW this is what I use personally. Note that these do not guarantee games will work, etc per Darkwizzie's guide.

Stability:
1) OCCT for 6-8 hours. This is by far my favorite, most sensitive test for my own system. Most issues detected bw. 30mins-4 hours,
2) if above passes, 30 passes of x264
3) Intel XTU Stress Test for X hours (this is a modified version of Prime95 afaik -- no high temps!)
4) Chess for 24hrs (it doesn't really affect my PC responsiveness so I can leave it on for days if needed)

If all these pass, I don't really bother with Prime95 or IBT but if I do end up using them for kicks
1) Prime95 blend (to test RAM as well and for lower temps) for 20 passes or so (which I can barely do at my stable 4.6Ghz voltages b.c. of temps)
If you do the "Small" test, temps will be even higher since cores get even "busier" due to no trip to RAM so be careful!
2) IBT "High Memory" for 20 passes (can barey do at my stable 4.6Ghz voltages b.c. of temps)

Benchmarking:
Intel XTU
RealBench
CineBench
MaxxMEM2

Happy Thanksgiving for those who celebrate it!

Ram Speed: 2133mhz CL9 - Corsair dominator platinum 16gb 2x8

Max temps are at 86c on prime 95 default blend test for 10+ Hrs
I hope to push this chip to 4.6-4.7 and then i will be very pleased, i can achieve 4.4ghz at like 1.23~ are the other voltages i should look at other than CPU Input voltage and Vcore? i dont wanna lower my ram speeds, cause i paid for the speeds im running at. Any tips to help push this chip a little further will help. Overall i can easily do 4.4ghz at 1.23~ so im happy
