Aida 64 memory testing is not a forte of the X3D It doesn't do well there.Flatlining target speed if temp headroom is available instead of floating like Zen 2x and Zen 3 Dual CCD chips. For those who used a Zen 2 x cpu and a Zen 2 xt cpu, it boosts more like the xt variant. PBO2 Tuner (link in post 13 by Lionvibes)allows CO and PBO limits to be manipulated (lower only), do so carefully if you it, it doesn't behave quite the same as other zen3s do.It's crazy hot, be ready, OCing on air or aio and keeping it cool is going to be a challenge.I got away with manually setting PCIE 16_1 to 3.0 and the m.2 drive to 3.0 YMMV, particularly with PCIE 4. PCIE will revert at some point as you climb BCLK, eg 4 to 3, or 3 to 2.No crashes, no CO used, no changes to PBO limits, LLC Auto. VID has never exceed 1.288, SVI2 has never exceed 1.269 using that small offset. My 105.4 BCLK has a +0.0125 offset applied, just enough to get it to boost properly again. VID is way under the Robert Hallock mentioned 1.3 to 1.35 vcore limit, low to mid 1.2s mutli core and high 1.1s single core, I verified with an accurate DMM and read points were ~20mv over reported SVI2, inline with previous CPUs that have been in this C6E.Avoid upgrading AGESA without research beyond 1206b for now if everything is working as intended, AMD can make permanent changes to the CPU and we all know how useful the notes are."Improved system performance".1203 - 1205 confirmed to boot and work, but don't have functional performance boost so it sits at base clock of 3.4 ghz. AGESA 1206b is the earliest found that operates correctly.Skatter Bencher #29 covers the method, all Crosshair boards with the BCLK overclocking support settings can do it.Initial thoughts on an early sample 5800X3D and some overclocking info/results. BELOW THIS ARE EARLY BETA BIOS IMPRESSIONS//
PLL of 1.85-1.95 seem to work well for higher FCLK.
