    Hello !
    I passed realbench with my i7 5960 x @ 4.5 Ghz and 32 GO of trident Z @ 3200 Ghz 14-14-14-32 (XMP) without error, but I get a few errors with HCIMemtest.
    WIch one must I trust ?

    HCI Memtest is good for testing memory overclocks. Yours seems to be unstable if errors come up.

    What about realbench ?

    a question about "The Uncore Story" ...

    I recently decided to start a new overclock, moving away from the 125 strap that I was using.

    As a refresher I re-read this guide. This section seems to say that cache voltage can be "in the region of 1.35~1.45V."

    Is that correct? and more importantly, is it safe? I've got my 5820k cache running at 4400 CPU with 4300 Cache (cache voltage ~1.245V). I would like to push further.


    "The Uncore Story

    Overclocking the cache frequency is not essential as processor core frequency dominates overall performance. However, if one wishes to experiment with cache overclocking - the cache frequency (AKA Uncore) can help boost some benchmark scores if run close to the processor core frequency.

    Good processor samples can achieve 4.6GHz Uncore frequency in tandem with CPU core frequency at the same value. Depending upon the processor sample, this may require cache voltage in the region of 1.35~1.45V."

    realbench is fine for benchmarks and stress testing. But only one error in HCI memtest deems your ram as unstable, might want to change the clocks a little

    I used to be able to pass realbench stable at 4.6 OC 1.26vcore, ever since i upgraded bios to latest 3001/2 just setting XMP and 4.6 with 1.35vcore causes bsod as soon as the computing starts.

    Anyone else having issues with their current OC after new bios? should i revert back? what would i lose going back to 1802?

    Great guide

    If increasing VCCIN from 1.90V does not allow a lower VCORE VCCIN may already be higher than needed. Lower VCCIN in 0.010V steps while testing for stability. Once instability is reached increase VCCIN at least 0.010V.*
    Very helpful advise. Thank you. I managed to decrease my core by another 0.04 at LLC 6. This also seemed to have general an *mpact on my system performance.*

    Guys how you set voltage for CPU Cache?
    On Manual, Adaptive or Offset.
    I kept on Adaptive but someone told me that not work and voltage will not drop in idle as CPU Core Voltage.
    I keep on 1.200V but it would be nice to drop in idle, but if not OK.
