    <br/>

    Stage 1 needs at least 195MB of ram, Stage 2 needs at least 4.8GB RAM... then stage 3 jumps to 46GB (so 64GB min with all channels populated the same on most platforms)? Bypassing the more common 32GB configuration? Very limiting for Stage 3 entries, no?</blockquote><br/>

    I guess that's starting to make sense now. I didn't realize that the gap between "stable" and "AVX-stable" is so large that you can be completely "stable", and yet fail immediately on <span style="font-weight:bold;"><span style="font-style:italic;">any</span></span> AVX.<br/>

    About the stage 3 size. I asked Massman about the 48 GB requirement, and he said he was okay with it since it forces people to run a large and stable memory configuration. Technically, you can still run it without enough memory if you use the swap mode. That basically turns it into hybrid CPU/disk benchmark.<br/>

    (snip)

    Yeah, it's really an 8 core thing. 8+ core E-class server processors will downclock when AVX calls are in the prefetch or stack due to the high current capability of the instruction set, so p95 stability with a 5960X for example will usually lower the OC by 1-200MHz due to neat management issues in most day-driver rigs. On Ivy 6-core or Haswell 6 core, p95 is not really a problem.

    Hopefully BW-E 10-cores can (somehow) address the heat-transfer issue at it's 10-core density. But frankly, p95 really does not put any higher logic stress on the architecture than many lower current stressors.

     

    Nice benchmark you worked out - adds the need for high load-current stability to the cpu benchmark set. The Kelvin cooler class will be burning thu lots o' LN2. :-)

    OC esports "Submit" link not working?

    Hello,

    Help!

    For the past two days when I hit the Submit button in an OC eSports comp - 5G tweaker for instance - it fails to load the HWbot page. On another rig, this is not occurring. Any ideas on how to fix the link for firefox (already reloaded 2x) or IE, or Edge? Seems like the link is broke for any browser on this machine.

    okay - found it. why this would apply to a product already available at the retail level is hard to understand: "currently available in shops". My specific 6600KES was a lab test animal subjected to brutal punishment - hence it's very poor MHz per mV performance as can be seen in the blocked sub.
