An update on my stress test "problem".
It does look like VDroop is the culprit.
No matter if I'm OC'd at 4.9, 4.6, 4.4 or not OC' at all(default 4.0 with core #0 at 4.2 turbo boost) I (only) when I stress test the voltage drops.
I found this while learning to use OCCT better, and it makes a series of chart shots save to .png files when it has run through. Here is an example of 4.6GHz:
voltage Vcore
Here you see that the LLC Ring stays steady although:
voltage LLC Ring
And the VID voltage looks like a heart attach:
So now I need to learn how to compensate(safely!) for it in MSI Click 5 BIOS
Load-Line Calibration: why overclockers should care - CPUs, Motherboards, and Memory - Linus Tech Tips*Given the small voltage tolerance that overclockers are working with (increased voltage is proportional to the CPU frequency/multiplier that an overclock can achieve), a droop in voltage applied to CPU can make a theoretically stable overclock unstable (dropping the voltage below that required to achieve the set frequency). *LLC applies additional voltage to the CPU to combat vdroop so that when switching to load, there is sufficient voltage to keep that frequency stable.
This one is for t5he Kaby owners(I mean you @Dude ):
Intel Launches Optane Memory M.2 Cache SSDs For Consumer MarketLast week, Intel officially launched their first Optane product, the SSD DC P4800X enterprise drive. This week, 3D XPoint memory comes to the client and consumer market in the form of the Intel Optane Memory product, a low-capacity M.2 NVMe SSD intended for use as a cache drive for systems using a mechanical hard drive for primary storage.
The Intel Optane Memory SSD uses one or two single-die packages of 3D XPoint non-volatile memory to provide capacities of 16GB or 32GB. The controller gets away with a much smaller package than most SSDs (especially PCIe SSD) since it only supports two PCIe 3.0 lanes and does not have an external DRAM interface. Because only two PCIe lanes are used by the drive, it is keyed to support M.2 type B and M slots. This keying is usually used for M.2 SATA SSDs while M.2 PCIe SSDs typically use only the M key position to support four PCIe lanes. The Optane Memory SSD will not function in a M.2 slot that provides only SATA connectivity. Contrary to some early leaks, the Optane Memory SSD uses the M.2 2280 card size instead of one of the shorter lengths. This makes for one of the least-crowded M.2 PCBs on the market even with all of the components on the top side.
The very low capacity of the Optane Memory drives limits their usability as traditional SSDs. Intel intends for the drive to be used with the caching capabilities of their Rapid Storage Technology drivers. Intel first introduced SSD caching with their Smart Response Technology in 2011. The basics of Optane Memory caching are mostly the same, but under the hood Intel has tweaked the caching algorithms to better suit 3D XPoint memory's performance and flexibility advantages over flash memory. Optane Memory caching is currently only supported on Windows 10 64-bit and only for the boot volume. Booting from a cached volume requires that the chipset's storage controller be in RAID mode rather than AHCI mode so that the cache drive will not be accessible as a standard NVMe drive and is instead remapped to only be accessible to Intel's drivers through the storage controller. This NVMe remapping feature was first added to the Skylake-generation 100-series chipsets, but boot firmware support will only be found on Kaby Lake-generation 200-series motherboards and Intel's drivers are expected to only permit Optane Memory caching with Kaby Lake processors.
And Linus say's:
Intel say's.
Oh, the ole VDroop and Load line issues/tricks. Leant about that when I was trying to stabilize an OC on an X58 Gigabyte MB. The trick is to find a LLC level without creating extra heat from the increase voltage required to keep the CPU stable at load.
LLC and VDroop are dependent on how well the MB is made and what components it uses. Some MB's are better suited to handle VDropp than others. This is where "OC" motherboards are "supposed" to shine.
Anyway now that you know what the culprit is, hopefully you can solve it. And again, remember not every chip is guaranteed to run 4.9 stable. Luck of the draw.
