Those of you waiting on an Apex are in luck! BH Photo is now shipping them smile.gif

Me personally will wait until the Canadian vendors start stocking them as there’s a hefty customs fee !

Edit - my will is weak, ordered placed for expedited delivery this Thursday! biggrin.gif

There have been numerous posts regarding incorrect VCORE compared to the voltage set in the BIOS. After some testing part of this can be attributed to incorrect BIOS settings or not taking into account Intel's programming of the VID tables.

All the screenshots below were taken with the same BIOS settings. All testing was done one after the other with no reboots in-between the tests. Software used was Prime95, HWBOT x265 Benchmark, CPU-Z and HWINFO. The DMM is connected at the CPU socket to eliminate PCB trace induced errors. The related BIOS settings are as follows:

CPU Multiplier - Sync Cores, 47 Multiplier
Cache Multipliers - Auto
AVX Offset - 0
CPU Voltage - Adaptive set at 1.27V
LLC - Level 5
IO AC/DC - 0.01
SVID - Enabled
SVID Behavoir - Best Case
Warning: Spoiler! (Click to show)
Prime95 Small FFTs FMA disabled, AVX enabled. Actual voltage under load 1.248V. VDROOP - 0.022V




Prime95 Small FFTs FMA3/AVX enabled. Actual voltage under load 1.246V. VDROOP - 0.024V




Prime95 Small FFTs FMA3/AVX disabled. Actual voltage under load 1.216V. Appearant VDROOP - 0.054V




HWBOT x265 Benchmark. Actual voltage under load 1.265V. VDROOP - 0.005V


As can be seen in the above screenshots reporting software is not accurate and should be used as a general reference only. With that in mind CPU Package Power can still be used for comparison as the actual measured current differences were similar. It's known that Prime95 Small FFTs utilizing any of the AVX instruction sets places a higher load on the CPU compared to the same run without using AVX. This is evident when looking at the reported power shown in HWINFO. The amount of VDROOP also increases as the amount of load increases. With these facts in hand it is obvious that the 0.054V difference in VCORE compared to what is set when running non-AVX Prime95 cannot be the result of VDROOP alone. It seems that when SVID communication is enabled the set VCORE applies to AVX enabled workloads and for non-AVX the voltage is substantially reduced. What appears to be excessive VDROOP is actually a difference of base voltage depending on the workload.

When moving away from synthetic testing and using tools that mimic actual programs VDROOP improves significantly as can be seen with the HWBOT x265 Benchmark. Even though AVX is used there is virtually no VDROOP when the system is set up properly. VDROOP can be further improved but consequences such as overshoot come into play. If relying on software reporting or limited in the tools available for proper testing 0.020V - 0.030V seems to be an acceptable VDROOP value for AVX enabled Prime95. Also depending on settings and the board venturing above 1.28V VCORE may result in voltage extremes not seen by software or DMMs.

Nice! Thanks. which bios?

Motherboard: Z370-I
BIOS Version: 0430

When you shut down and unplug the system, it loses the RGB lighting setting (off becomes on). When you plug the system back in the RGB lights immediately turn on even though the system remains off. After powering up the system, the lights remain on until you enter the BIOS, then save and exit (no changes are made).

One more: "Ring Down Bin" defaults to disabled which is the opposite of what the description text says.

It should be Auto as the Default - right?

Auto is the default setting and the default behavior of it is "disabled". However, the description text says the default behavior of Auto should be "enabled". Clear as mud, I know.

The OP in the following thread shows how to properly test your memory for true stability.

Thanks for your suggestion. I wasnt explaning myself properly. I ment that the PC wouldnt even post. I agree that booting into Windows isnt a measure of stability. Yesterday I left my PC with CPU and GPU at 100%, with distributed computing an mining, for 9 hours straight and no stability issues. I might use the test you suggest, but so far no stability issues even with good stress for the PC.

Bought my self a Maximus Hero X and a 8700k, got it running at 5200mhz.
Got it delidded and at this volt it doesnt get hotter then ~75c - 77c while stressing it and while gaming around 40-50c.

Also got the memory running at 3700mhz at 1.450v (up from 3200mhz)
So far it runs really smooth and im very happy with the system.

nice! I'm really liking this 8700K. Very "snappy".
