An update: this is a BIOS bug but there is a work-around. I have been testing several systems (Z77 and H97-based) after I disabled all references to 'xHCI' as it pertains to USB settings[1]. I also enabled wake on keyboard[2]. And finally, I disabled EuP 2013 which affects wattage in power off...

OK, ran out to ~200 hours and as expected, no change in the conclusion. The original post was updated with these results.

I honestly never observed temps going up over time...

@flod - No, too much work since you can get a "bad mount" thus the need for replicates. Someone did this (3 or 5 mounts) per paste and published it. You'll have to google for it. My particular study is less affected by mounting variability I think since any curing effect should be similar as...

Purpose According to the manufacture of AS5, there can be up to 200 hours of break in time required for temps to stabilize. This claim has been tested the results are shared in this thread. Materials, software, and experiment A delidded i7-3770k (over-clocked to 44x100 with fixed vcore) was...

Consider the results I presented invalid. I did not control for the FFT size (thought I did but later realized the defaults define a range). I edited the first post of this thread and will repeat.

I compared Arctic Silver 5 to MX-4 between my new i7-4790K and my NH-14D. In short, I ran mprime (Linux64,Prime95,V28.5,build 2) using large FFTs with 8 threads and logged the temps throughout the run once per second using a shell script. Ambient temp which is very important to consider did...

Under linux, displaying the processor's pstates can be done with programs like i7z, powertop, or turbostat. Can someone recommend a Windows utility that can display processor pstates? % sudo i7z Cpu speed from cpuinfo 3500.00Mhz cpuinfo might be wrong if cpufreq is enabled. To guess...

I just tested it under windows 7 to see if it was a Linux problem, or universal. This machine runs Linux.

Booting into windows 7 and then shutting down from there does not exhibit this behavior. It seems to be something unique to Linux...

This is the only issue stopping me from recommending the board at present. It is fine otherwise, but if you need WOL it is a critical one. Can you post a few links to the posts to which you refer [i.e in the NAS and HTPC forums]? Thanks you.

Odd, I too have this drive. Here is the output of the seagate tools drive detector: Model: ST3000DM001-1CH166, Serial: X1X4C0XX, Firmware: CC29 The error would appear to be in the firmware since smartmontools also reports this as the model: # smartctl --all /dev/sdb smartctl 6.2 2013-07-26...

Update - Latest BIOS 1005 does not fix this problem and 14 emails between myself and the people at Asus who barely speak English have not been fruitful.

If not in the BIOS file, perhaps in the BIOS on the board.

@Blue - Thanks for the confirmation. It is likely something intrinsic in the BIOS then that occurs when it detects bad blocks. Mine is an Asus P8Z77-V Pro... what is your board?

@Ehren - Yes, but did it look and say exactly what mine did? I would have expected to see the Asus branded, colorful flash util but these was black and white as I described making me think that it was not a vendor thing, but something external.

@Bluesun - OK! So you can confirm the "bad blocks in BIOS" hypothesis? When your overclocking some how triggered a bad condition in your BIOS, you saw exactly the same message as I did? BIOS is updating. Do not shut down or reset the system to prevent system bootup failure. xx% complete

Only if it were an iphone.

Ha, me too. Nothing from rkhunter either.

Thanks, I am using clamav now but haven't detected anything... http://www.clamav.net/lang/en/

@radgoos - Nothing connected. I did flash to the latest BIOS on a fresh USB. @CacaSapo - This machine has never seen windows; it only runs Linux. Not sure what kind of virus scanner to use... any recommendations? EDIT: http://www.clamav.net/lang/en/

Just experienced something very odd. I switched on my workstation and was presented with an unfamiliar and simple black screen/white text which read something like: BIOS is updating. Do not shut down or reset the system to prevent system bootup failure. xx% complete Board is an Asus...

Yes and yes :)

In order to support WOL, my Asus H87I-Plus requires an option set in the BIOS (Onboard>APM>Power on by PCIE). When I have this enabled, I can indeed start the machine using the wol magic packet, but there is an undesired side-effect: about 25 % of the time I shutdown the machine, it stays shut...

Bumped to mentioned that I updated the main post to recommend using two additional 'stresses' including x264 encoding and compilation of something large like the kernel itself. On my current i7-3770K, I recently discovered that my long-time stable settings have become unstable, requiring an...

Not gonna happen :p

Interestingly, the lower offset (-150 mV) only translated into -1C drop across cores: Squares are the offset of +0.020 V and circles are the offset of +0.005 V. Here are a few visuals on the VID distributions. Remember, my script is sampling 30 times/sec and that on day 4, I dropped the...

I was able to drop my vcore offset from +200 mV down 150 mV to +5 mV and have a stable system as evaluated by: 5 h of mprime large/FFTs, 2 h of continuous compiling, 2 h of systest 64M, and 2 h of linpack+gcc. Lower operating temps have their tangibles. This is @ 45x100. I'll now switch over...

@WFD - Thanks and right back at you. You planning to use LP on your die?

I updated the first post of this thread with new results having lapped both the IHS and the base of the heatsink. They start under the section entitled, "Part 2."

I've read that LP can damage parts if you attempt to remove them after months of usage as it will literally bond the two metal surfaces together. Is this fact or rumor?

Worry about something else. This is the manufacturer's recommended method. Has been just fine for me.

Depends on the type of TIM. AS5 in my experience gives best results both 'tinting' the HS and using the line method. MX4 on the other hand works equally well spreading it with a plastic bag over your finger or using a small drop and letting the HS do it.

Arch has been my home for several years after distro hopping. I love it. Here are the links to the non-repo packages for stress testing under Arch: mprime -- https://aur.archlinux.org/packages.php?ID=56009 linpack -- https://aur.archlinux.org/packages.php?ID=34243 systest (superpi) --...

TL; DR Summary The linux kernel is a powerful tool to detect instabilities in your overclock settings with both greater accuracy and sensitivity than either Prime95 or IBT/LinX. More Details The linux kernel supplies users with a dead simple method for measuring hardware instabilities -- like...

First post updated

PART 1 Introduction Feeling somewhat curious about the reports that inferior Thermal Interface Material (TIM) ships from the factory inside Ivy Bridge (IB) chips, I found myself taking my new 3770K out of the safety of its socket this afternoon and on to my desk where it went under the knife...

I have the system described below overclocked to 45x100 and am prime95/large FFTs now to test for stability. I didn't do a whole lot of tweaks but I do want to share the settings I am currently testing and get feedback: 1) Others settings I should tweak? 2) Are these values sane? 3)...

I am considering this CPU and wanted to ask if anyone has this chip to run a linux-based benchmark for me. How long does it take your system to compile the Linux kernel? To make things easy, I tarred-up and pre-configured the linux source for v3.4.5 and am hosting it here. You may use a...
