Ah, thanks. Good to know. Is there a schematic somewhere for the Z170-Deluxe, what ADCs are used? Just asking, since not all voltages I monitor show a 16mV resolution. VCCSA for example, shows 1.080V which is clearly not in the 16mV grid. I would be nice to know the resolution of the specific voltage readings.

Thanks,
Matthias

Hello

If accurate voltage reporting is required a DMM with the required resolution and precision should be used.

I am currently trying to find an instability issue with my new machine and I am just trying to figure out the resolution of the different readings. That is all.

Thanks,
Matthias

Hello @all...

I would like to kindly ask for help on an instability issue I have. Even though I already posted this over at the G.SKILL and MersenneForum, I will summarize it here again:

Basically, if I run Prime95 v28.9 blend stress test, sooner or later, the test will error out on a worker. The time is unfortunately spread rather wide: 13h, 19h, 39h, 49h and today 14h. The FFT sizes for the last three failures were 8k, 800k and 320k. The failures are always zeroed results like "FATAL ERROR: Final result was 00000000, expected: EE20AC08" and never rounding errors.

The system is generally not overclocked -- except for the memory and thus system agent and imc. But the last few tests were done completely at stock, meaning the memory was also clocked at DDR4-2133 @ 1.20v and everything at stock voltages.

MemTest86 v7 Pro with parallel testing on all cores revealed no errors but I have to admit, the longest I had it running was for 13h since I do need the machine for work.

I have meanwhile swapped the memory kit for the exact same model and the last failed test was performed with the new memory kit. Prior to that with the "old" kit, I also raised the VDIMM voltage, which had no effect either.

Temperatures are all in the green since the case is well ventilated and the CPU is kept well in line with a Noctua NH-D15S. During the test, I monitor everything with 500ms resolution through HWMonitor64 and see no anomalies whatsoever.

Here the specification of the machine:
  • ASUS Z170-Deluxe with EFI firmware 1902
  • G.SKILL Trident Z F4-3200C14D-32GT
  • Intel 6700k (MC 74)
  • Corsair HX850i
  • Zotac GTX 1080 FE
  • 4x Seagate ST2000NM0033 (Intel Rapid Storage RAID10)

The magic performance enhancements in the UEFI firmware are all off. Everything voltage related is on Auto. I also tried setting Vcore to Offset with SVID enabled, but that made no difference either.

I am now considering swapping CPU and board but since I cannot really locate the culprit, it leaves a very bad feeling that this becomes an endless cycle/story. I am still not 100% convinced that this is not another Skylake and/or Prime95 bug. Over in the MersenneForum, another user reported he is seeing the exact same behavior on a different brand board -- which naturally can also have an absolutely different cause. I know. frown.gif

If anyone has any ideas or suggestions... I would really appreciate any helping hand. This is really grueling since I need the machine to be stable and dependable. And since I am walking in the dark here, it is even more frustrating. With real software bugs, I can at least have a look at the sources and fix it myself... but that is sheer impossible with hardware. :-(

Thanks so much in advance for any help,
Matthias

I can't tell any difference running 1902 but it's possible that the changes benefit those running faster RAM than I...I've heard that on another ROG board but not sure if it applies to the Hero or not.
But for sure, nothing about 1902 is worse in any way for me...I had to make no changes to any BIOS settings and my overclock is the same.

Nope, they aren't stickers, they feel like paint, the pch heatsink looks like it could be pried off

You might be able to put some vinyl over them, but heatsink itself feels like anodized aluminum, if they are wet mount decals you'll have to remove the heatsinks and soak them then using isopropyl alcohol to clean off the residue, if it is paint, there really isn't an easy way to remove it without taking the anodized layer off with the paint, maybe goof off.

either way good luck, i wish more manufacturers offered a set of plain/different colored decals for boards over $150, make them cost $10-15 for a set

i should also mention, there is a red standby led that you can't disable, so you'll have to cover it with something anyways

Forget Western "Six Sigma" style concepts and embrace "well enough". China has been dragging the rest of the world down that path for quite sometime now. Replace Prime95 with something like RealBench and see how that works out.

Unless you have more money than brains, I wouldn't be picking around on a layered mother board with any kind of a voltmeter unless you are a "skilled" technician and in a lab environment. It's even risky using a scope unless you are experienced. Over 50 years of experience speaking - not trying to gouge you as it's all in the realm of common sense.
