    Update:
    I got impatient after 24 hours of stable at 4.5/4.2 (see above). I've enabled speed-step AND C-states, but disabled the "enhanced idle" option which smelled suspcious given that my issues relate to what the chip does when idle not under load and more typically it crashes in the middle of the night doing exactly nothing. So far it is looking like I am on to something with that. Very different and much better behavior.

    So, I:
    1. re-ran Aida for an hour at 4.7/4.2 1.25/1.0 (adaptive/offset respectively) - no issues
    2. went back into linux and did my usual exemplar stresses and then idled:
    a. my desired CPU frequency behavior is now back (it drops down to 1200 and stays there with typical "surfing the web" loads and spins up quickly to 4700 with real load.
    b. my idle temps are back down where they should be (25-28C core temp vs 30-32C)

    So far, so good after 8 hours. This is what idle _should_ look like:
    cpu MHz : 1242.890
    cpu MHz : 1200.117
    cpu MHz : 1199.882
    cpu MHz : 1200.117
    cpu MHz : 1200.000
    cpu MHz : 1200.000
    cpu MHz : 1200.000
    cpu MHz : 1200.000
    cpu MHz : 1208.437
    cpu MHz : 1219.453
    cpu MHz : 1282.382
    cpu MHz : 1202.109
    cpu MHz : 1200.703
    cpu MHz : 1201.875
    cpu MHz : 1201.289
    cpu MHz : 1256.718

    I haven't explored higher cache frequencies voltages much other than to see that:
    a. I don't gain significant performance from 4.2->4.5 (far less than 1:1 on already small percentage increase)
    b. so far I appear to need significant cache voltage to do that (1.3 vs 1.0 for 1.2)
    c. still hunting for rock solid stable with cache above 4.2 w/low voltage
    d. yet more variables, so I will explore that once I am convinced the idle issue is gone.

    I want say something about lastest Bios,im super stable with 2001 bios but when im flash 3xxx series bios my stability was gone and tembs are was high.2001 bios for me best R5VE bios ever.

    Thanks, I haven't tried to go back as I needed the BW-E support. No issues on the X99Pro with the latest though... Certainly read a few people seeing issues though. The only thing I saw was 1T timings were a no-go on memory.

    Nice work guys
    some very interesting info. thanks for posting.

    Even on SS running RB over 1.4v will all most always crash on me. when running the encoder part of the bench it will pull down the SS to -18c = 66c core temp. it will crash every time.

    speed step and c states off also multi core enhancements off

    Did you notice higher temps with higher cache voltage?
    higher cache speed over 37 i need a voltage adjustment to say 1.357v that will pull 30+ amps on the 12v rail and the percentage gain vers performance gain just isn't there for me. still testing.

    Definitely higher temps.

    With the BW-E, I'm stuck at 3.7 for stable @ 1.29v. It can do 3.8 at 1.32, but if I run memory stress long enough, I get single bit corruption reported in stress-app. Despite no crash of BSOD, if stressapp sees something, it will _eventually_ bite you somewhere. So, not worth it.

    With HW-E, that limit, for my chips, remains 4.2.

    Between 3.0 and 4.2, I see linear improvement in my various use-cases. 10% more cache gets me 10% more performance. So, 3.7->4.2 is another ~10% that I can't get, but the chip will do what the chip will do.

    Yes HW-E I do much better Core to Cache - performance.
    BW-E not so good. I read you mention the 6950X has trouble @ 5 GHz your right. I also have a 6900X that seems to be a real dog past 4.8 GHz that is in my RVE. I am going to move it to my X99 DELUXE II and see if it will perform better.
