Soooo are we going to get in-bios stress test on z370? Coffee lake is arguably the larger enthusiast and overclocking consumer, not to mention a generation newer than x299/skylake-x.
 
Also, the lack of vdroop control / LLC really is the only downfall of the EVGA z370 lineup.. If we get those two things I'd buy another EVGA board for the impending 9700k. Without it.. i'm not sure.
 
Edit: to clarify, the current implementation of "cpu vdroop - disable" simply tacks on 80mV (which is huge) when under load and is largely a useless option. I.e. if you put 1.3V and disable vdroop, actual voltage will be over 1.38V. If you use adaptive, it scales with VID so you may end up 1.4V+!!! That's unacceptable!
 
Edit2: Also remove the minimum Vcore of 1.2V because some people like to minimize voltage at stock clocks.

    This!!! The absence of these features (minus in bios stress testing) are why the initial reviews (at least of the classified k) were so poor, leading to such poor sales that it's impossible to find any monoblocks, vrm cooling, or any other add-ons. To cool my vrms I had to buy universal vrm blocks, then put it on my bench grinder, and grind the WIDTH of the blocks to within a few millimeters of failure just to make them fit! It's baffling why these features aren't implemented. If they were implemented I'd buy nothing but evga Motherboards.

    Um... lets just clarify that no companies have made monoblocks or waterblocks for EVGA motherboards, and it had nothing to do with the discussed info above. I havent seen any company make block for EVGA motherboards in a very long time. A forum member here used to make them, but I am not sure if he is still actively doing that anymore.

    EVGA motherboard sales do not compare to other companies, and it would seem that is why most companies do not make dedicated blocks for EVGA.

    The HEDT costs 4x as much as the consumer products when you compare the motherboard and cpu prices together. If they are going to bring the bios overclocking to the mainstream, it will probably be in the near future. I do know that there is already multiple people asking about it on the thread that launched the oc robot feature, so give them time for that to come out.

    Z87 classifed $229 currently + i7-8700k $350 = $579

    X299 Dark $399 currently + i9-7980xe $1849 if you can find it at the right place = $2248

    X299 is still used more by K|ngp|n, who is one of the top overclockers in the world, so his hardware usually brings things to the scene first. It has more funding to back it. It usually trickles down to the consumer platform later. Also, x299 has only had one release. The next HEDT should be on x299 as well, which means a bigger, even more expensive processor that has more power.

    Thank you for pointing out the fallacies in my post. I made said post with inadequate knowledge.

    I'll put it this way. If you use 'Vdroop Disable' and try maxing out your OC you may actually have transient voltage spikes high enough to fry your cpu. Very unacceptable!

    I haven't had any issues with

    All core: 50

    Ring ratio: auto or 47

    Avx offset: 0

    BLCK: 107

    Vdroop: disabled

    Vcore - adaptive

    Target voltage: 1.200

    Offset voltage: +0

    Puts out 1.36 doesn't spike past that.


    Now I had to enable Vdroop when doing an all core 40 and a blck of 133.5. Don't know why, but for me I only has spikes with Vdroop disabled if Im trying a high blck clock.

    The polling rate of most hw software wont actually catch the spikes when a load is put on the CPU. They're transient in nature and happen at a frequency that you'd have to put an oscilloscope on it to see. Its quick and temporary, but its there and can damage your CPU.
     
    To understand why you have to know what vdroop is an why intel created the load-line. Voltage doesn't drop on the CPU because of the increased amperage from a load, the VRM is capable of managing that to keep constant voltage. It actually drops because intel specifies that motherboards must do that in order to compensate for the transient spikes when going from no/low load to high load as a matter of protecting the processor.
